Jacko's New Wheels

Article and words courtesy of Jacko Whacko!

Hi, finally installed the RPF1 after about 12months of considering it.... since boss gave us half day today, I headed down to the tyre shop for the installation. Paid the following

RM1850 for 4xrims + rim centering spacer + Alu Valves (New, after trade in old rims)
RM430 for Rays lugnuts
RM50 for new tyre removal tool

Need a new tyre removal socket as the Rays are 19mm and our original ones are 21mm.

Rims are light wei, handling went up one notch!! These are 16" and Enkei says it weights 13.7lbs = 6.2kg. The 15" are even more anorexic weigheing only 9.8lbs = 4.9kg. My tire guy initially bought in one 15" (silver) and two 16" (white). All of them are gone and I guess he wants to clear this. From what I read they are also very strong. I'm hoping that they will be excellent for track day. The car drives differently, small bumps and mid undulations are not so obvious now... reducing the unsprung weight also cause the steering to be a tad lighter and sharper.

I cant seem to find the center cap for the rims in Msai. To buy on-line is just to x, one will set you back US35.. OUCH!! Crazy man .. if any of you got jalan pls let me know, pics attached. They are special sized made for the Enkeis' only .. DUH!!

Got a set of Rays lugnuts too. These are the longer version ones, according to tire guy this is suppose to be better as they prevent scratches on the rims. Who says you cant have your rice and drive it too!! Hahahahaha ..... The rims even got a few eyefull from a bunch of ah bengs that were hanging around waiting for their carpet-zebra stripe dash-super spoiler vortex generator-brembo cover-hello kitty-interfooler super monster beast doing their alignment. I'm also a bit worried on caps of the aluminium valves beind nicked. Just yesterday I lost 3 on my old rims.. the new ones being a shade of ah beng blue .... sigh : (

There is also this ultralegga staring at me .. its nice and even lighter but out of my budget. Rims being white will have a headace cleaning it.. hopefully the guy that washes my car 3x a week wont complain too much... else have to top up his fee and buy him a can of rim cleaner every month.

I'm getting this for the price and performace and am hoping that the looks will grow on me ......

(Andrew) 16" Virgin white RPF1s

(Andrew) RPF1s installed with blue anodized Rays Engineering extended length lugnuts. Got Bling?

(Andrew) Lightweight aluminium air valve. These come with the RPF1s. Jacko, next time pls clean the wheel first before taking pixslar..

(Andrew) Now is this the fiercest looking SGTI in all Malaysia or what?

Happy Chinese New Year!!!

I would like to wish Everyone A Very Happy and Prosperous Chinese New Year!!! May The Coming Year Bring You Lots of Joy, Wealth and of course More Mods!

On Cloud 9!

The SP was recently dynoed by it's new owner at GT Auto. Engine spec and tune is exactly the same as when I sold it cept for a Koyo aluminium radiator fitted a couple days before the dyno. I'll let the dyno chart below tell you how pleased I am with the results. Absolutely fab and worth all the BST thru the years!

If you're having difficulty with the maths this translates to more than 180ps at the crank once you factor in transmission loss. At least 5 more ps can be liberated by fine tuning the A/F ratio. As you can see the mapping's too rich from 4000+ rpm onwards. I would also tweak the cam lobe separation settings for more torque. Pls note that this engine is still running on hydraulic lifters. Cylinder head is standard fully ported 4G93T RS. Engine is Naturally Aspirated. No MIVEC or Snail cheating here. For comparison sake, a stock B16A big VTEC will dyno around 140-145ps. A B18C Spec R will dyno around 160ps. A stock 4G93P will dyno around 110ps or less.

The new owner has lotsa mods planned to take the SP to the next level. Most importantly he also has the budget I don't have.

The End of an Era The Beginning of Another

All,

My apologies for the long delay in posts but I've been swamped with work and my new house. With great sadness and also happiness I'd like to announce that the SP has been sold and the new owner has already taken delivery of it. The monster is already roaming the streets of the Klang Valley as we speak. I'll let the new owner introduce himself in due time but suffice to say he is a car mod enthusiast and bought the SP nearly lock, stock and barrel. Mr MB already owns a trick car and has exciting plans to continue the development of the SP. I'll be sticking around this blog and should also be starting another soon on my Sentra. The N16 Files will however be more on general maintenance, ICE and oldie comfort (shudder) mods rather than all out performance. Getting a bit grey unfortunately. Stay tuned...

Price negotiable. Serious enquiries pls contact me @ llsaw1@yahoo.com. And I really mean serious enquiries. Selling things on the net is becoming a big hassle nowadays. Lotsa emails for pixs requests, etc, etc and that's it. Also I know the market price and what I'm offering. No offence but contact me only and only if you can really afford. Also if you have a counter offer pls make it reasonable. Do not waste my time and yours. As an example one person tried bring the price of my Sentra's less than 2 month old CD MP3 head unit to RM150 when a brand new set will set u back bout RM600+.

So the answer to WHY?
1. I barely have time nowadays to mod or run the SP. Only ever run the SP during weekends. Mileage is down to about 30-40km per week.
2. I don't really have the excess cash to justify playing around with 2 cars. Make that 3 if I include the other half's Optra.
3. Getting really disillusioned and sick with having to do nearly every other mod myself and with the local mod industry. There's still no dyno today in Penang so this means any engine mods means a trip down to KL. I've also been waiting for some development parts for close to a year.
4. To really further take the SP to the next level would require big big bucks. Something which I can ill afford as I have a semi-d house which I need to furnish and renovate. That should nicely take up all my time and finances for the next 6 months or so.

To sum it all up time is catching up fast. I'll continue this blog to the best of my ability as I still have lotsa remaining articles to write. Plus the development continues as my bro Jack is getting some of the SP's works parts and is continuing to push the barrier! Finally to all you fellow Proton Wira, Satria, Putra & GTI/SR3 enthusiasts out there I would like to thank you for all the compliments. You guys and gals (I hope) have been wonderful. It's been great running this blog. Keep the mods coming.

Race Tech Magazine Braking Upgrade Calculator

The link below brings you to a very nifty Microsoft Excel spreadsheet which automatically calculates your braking requirements and upgrade to generate the ultimate stopping power you aspire to. The tool even calculates for you the weight transfer under braking for your car, how much stopping power you are generating at each end of your car and even possible caliper piston sizes vs master cylinder ratio. So if you even wondered whether this 10 piston caliper with 40mm diameter pistons and 350mm diameter rotor will suit you car with a 1" master cylinder use this tool. Fab stuff! I spent countless time playing with the thing.

Race Tech's Braking Model

For starters try this. Stock GTi/Putra uses a single piston sliding caliper with a 54mm diameter piston, 256mm front rotor/260mm rear rotor and 15/16" or 23.8125mm master cylinder. The EVO1-3's twin piston caliper uses twin 42.9mm pistons, 276mm front rotor/260mm rear rotor and 1" or 25.4mm master cylinder. First person to calculate the difference in piston area for the Putra vs the EVO1-3 and the disc/rotor torque on one wheel assuming both use the same coefficient friction pads wins a free teh tarik from me :)

And pls.. Getting your stock rotors drilled will not give you more stopping power. Period! It will only make the shop drilling your rotors richer at the expense of your money.

Ralliart Engine Mounts

Most petrolheads get excited when “glamorous” mods such as turbokits, bodykits, gt wings, cams, intakes and exhaust are being discussed. Tell them you just spend a couple hundred bucks on engine mounts and the exclamation would be “WTF!”

Like suspension bushes, the engine mount is an indispensable part of a vehicle. It’s simple function is to attach the engine to the vehicle at it's designated position while eliminating vibration and unnecessary engine/gearbox movement. If you’ve got 25% or more additional power from the engine it’s time to look for stiffer mounts as the stock softy mounts are probably way past their limit. And no you won’t get 25% more power with just an intake, header and exhaust. If you persist problems such as broken engine mounts and exhaust will occur in due time. This is due to too much engine movement as the stock mounts are unable to control the engine movement. Having previously broken my exhaust twice due to too much engine movement I can tell you this fact is true.

I was originally using the WRC Motorsports upgraded solid engine mounts but these do not last. The bottom mount cracked in less than 3000km! The term “solid” means there are no gaps or holes in the engine mount’s rubber leading to a stiffer mount. Have since upgraded to Ralliart engine mounts for the 2 bottom engine mounts while retaining the WRC Motorsport mounts for the other 2 top left and right engine mounts. The 4G93 uses 4 engine mounts to hold the engine to the chassis. The are 2 at the bottom controlling longitudinal movement (front and back) and 2 on top at each side of the engine controlling transverse movement (right and left). This mounting config is the same for all variants of the 4G92 and also the 4G63 EVO1-3. The Ralliart Group N engine mounts are made from HS80 rubber for the bottom 2 mounts and HS90 rubber for the top 2 mounts. They are very hard. My advice for most people is to only upgrade the bottom 2 while retaining the stock for the top 2. If you’re a sucker for punishment or have a vibration fetish you can go for all 4!

Picture below of the Ralliart front lower engine mount (Part Number RA581297K1).

Picture below of the Ralliart rear lower engine mount (Part Number RA309269K2).

As you can see from the pixs above these mounts are really beefy and hard!

The part number for the top 2 mounts is RA871602K1. The part number is the same for both (left and right) mounts. Do bear in mind the Ralliart engine mounts do not come with the mounting brackets so the stock mounts will have to be pressed-out of the stock brackets and the Ralliart mounts pressed-in in place. I elected to buy new stock engine mounts complete with brackets as these are fairly cheap. Dutifully sandpapered the stock brackets and had them resprayed in matt black. With the new mounts installed engine movement is totally minimized under hard acceleration and shifting. The other positive side effect is quicker shifts as a result of the minimized engine and gearbox movement. The downside to all this would be even more vibration at idle but hey if you’re on big cams big deal! If you want less vibration try something softer like R3 engine mounts. I would stay away from the WRC Motorsports engine mounts (at least for the bottom mounts) as they don’t last. A flashy engine damper might make the engine bay look racier but they cost more (the branded ones at least) and the effect is not as good. Nothing beats upgraded engine mounts IMHO. Also if you’re curious, race-only cars run aluminium/metal engine mounts.

Got Roll? Upgrading the Anti-Roll Bar

The Putra runs a pretty archaic and basic anti-roll bar setup. As you know an anti-roll bar is a very useful component to dial in a car’s handling by controlling the understeer/oversteer characteristics apart from reducing body roll. Mike Kojima’s excellent article on dialing in the ride and handling for a Sentra which has a similar setup) is a useful reference. Uncle Sam people like to call the anti-roll bar an "anti-sway bar" while most manufacturers typically call anti-roll bars "stabilizer" bars in their brochures. They are all the same.

For some apparent reason the 99 year and post-spec Putra runs an 18mm diameter front arb setup with a 13mm rear. Not sure why Proton reverted to this setup as ealier pre-99 spec Putras were running a 23mm front arb. Maybe to ensure the Putra handles inferior compared to the GTi? ;) The Wira/Satria 1.6 and 1.8 runs a similar (23mm front) setup. Compare this to a DC2 Integra Type R for example with 24mm front and 22mm rear 96 year spec setup and 25mm front/23mm rear for 98 year and onward models. BTW the Wira/Satria 1.3 & 1.5 runs a front 18mm arb with no rear arb. You get the picture? Arrrggh! The anti-roll bars use a horizontal blade attachment point and the arb links are merely vertical rods with 2 pieces of rubber to act as the arb bush with the arb sandwich in between. This is the same for the front and rear. Pix of the front arb attachment point below.

The front arb is attached to the front lower arm and the rears also to the rear lower arm. GTI in comparison use a "direct acting" front setup with the arb itself directly connected to the front strut via a ball joint type arb link. The arbs have vertical end blades. The rears also use a similar setup but with the same mounting points as the Putra. The ball joint link is far superior to rubber bushes as unwarranted flex is eliminated. It is however far more expensive than rubber. A set of GTi arb links will cost you RM300+. Per end of car! The end links cost more than the arb itself! If you must know the GTI runs an 18mm front setup and 13mm rear too but the front direct acting setup and the use of much better quality arb end links means the arbs give a much better effect equivalent to going to a bigger diameter bar.

When I upgraded the SP’s arbs I was looking to reduce some roll inherent with the DMS 50mm setup as the double progressive springs are wound pretty soft at the beginning compared to a linear spring setup. I decided to "upgrade" the front arbs back to 23mm stock Proton/Mitsu arb instead of going the GTi route. The Proton/Mitsu part number for this arb is MB844453 and the arb is pretty cheap @ around 200 smackers. Reason is if you go to a larger diameter (>18mm) GTI front arb setup there is a tendency for the arb mount flange on the strut to fail. I am not sure if this problem is only inherent with the DMS shock’s flange but the fact that Mitsu reverted back to the front arbs being linked to the lower arm for the EVO4-9 tells the story. One of my Brudder’s actually cracked that flange twice on the track and had to send the shocks back to DMS for additional welding and reinforcement. Not a nice experience. I also upgraded the "D" bushes (Part No: SPF1572-23K) and the arb end link bushes (Part No: SPF2092BKP) to Superpro polyurethane (PU) items. PU is stiffer than rubber and has way less flex. For those of you in the know, Whiteline already supply Superpro oem PU "D" bushes which come free along with the arb itselft so why am I buying them separately? Pix below shows why.

No offence but no way I'm going to put yellow arb "D" bushes along with my silver arb. They look more like sorbet or egg tart. Got rice? At least the Superpro ones are dark purple blue. If anyone's interested these VERY YELLOW 18mm rear arb PU "D" bushes are yours for RM25. Buzz me. If you must Whiteline sells a stiffer front arb too but at only 24mm diameter I personally feel this is not a big enough upgrade in stiffness ratio for the price you are paying. The part number for this arb is BPF14. Pls ensure you change the "D" bushes to one that allows a 24mm arb.

For the rears I decided on the trick GTI ball joint setup. This means that I will have change and upgrade not only the arb but the end link itself. Now this is going to sound most interesting to those who think the GTI is Lotus Tuned Handling. The part numbers for both Mitsubishi Mirage/Lancer EVO1-3 rear arb end links are the same. Still unconvinced I purchased the links from Proton and a similar link from Mitsubishi Japan to compare. Picture below of the EVO3 rear arb end link and packaging with part number. Make your judgement.

Worse of all PESC is charging bout RM320+ or so retail for a set of these end links whereas I can get a similar set of brand new end links air freighted from Mitsu Japan for less than RM290. And guess what! The same also applies to the fronts! Also purchased new nuts and washers from Mitsu Japan for this project. I decided to go to an adjustable rear arb from Whiteline. Part Number: BPR16Z. An adjustable arb means there are more than one mount holes on the arb end blades for you to adjust the stiffness ratio of the bar by connecting the end links via these holes. The "closer" hole mount point will give a stiffer ratio vs a "further" mount point. The Whiteline adjustable arb has 2 holes. I have seen some setups with 3 holes. And yes, Whiteline sells both adjustable and non-adjutable front and rear arbs for our cars with different diameters. You can look at them all here in Whiteline’s comprehensive on-line catalog
The newer Whiteline arbs have a silver powder coating and look way better aesthetically compared to the Smurf Blue older versions. Quality is pretty decent but I was pretty unhappy bout the end blades. They look uneven compared to say something from Cusco. Pix of my arb below.

Also upgraded the rear "D" bushes (Part No: SPF1826-18K). Pix of the installed setup below. You can clearly see the new GTi/EVO2-3 spec end links and how the arb is connected to the end links. Also in the pix is the purple bling coloured Superpro arb "D" bush. At least it's not yellow. Can hear Coldplay singing that darn song in the background. Urrrgh!

Another pix of the new setup. The project was done way back when I was still using Yokohama AVS ES-100 tyres. Pardon the confusion.

With these upgrades installed, understeer is greatly minimized and you can rotate the Putra during corners far easier than the stock setup. Overall a very worthwhile but expensive upgrade. The whole project cost me in excess of RM1.5K with the Whiteline arb being the biggest hit at 750+ smackers or so a piece. If you think this is not hardcore enough Jacko Whacko is currently on a project using spherical bearing end links. These bearings were actually being passed around for licking during his wedding dinner! Lotsa customized machining being done to fabricate the bearing mount shafts. Sneak pixs of the project below. Just look at these end links compared to the stock GTI links. Farkin Huge! No limits to the Madness!

The longer link is the front btw. Pix below of the rear arb setup on a Realtime Acura RSX aka Honda Integra DC5 touring car participating in the US World Challenge Series. The arb blade and end link is shown in the red bordered box.

The arb is in the boot itself and is an adjustable hollow tubed assembly. Still the arb rate is unbelievably stiff. If engineered correctly a hollow tubed arb can be made lighter while maintaning the same stiffness as thinner solid tubed arb. Also noticed that there are no bends on the arb as there is no need to clear chassis and suspension arms in this setup. Not sure of the material used for the arb but on World Rally Car's it's titanium.
Another pix of the rear arb link and the funky looking rear suspension arms. The next time a manufacturer proudly boasts their Civic, Integra, Impreza, Evo or even the Hyundai Accent RXS is nearly the same as the works car being raced/rallied in top level competition you will know better!

Will talk about my rear suspension arms and links next. And also a feature on Superpro suspension arm bushes. Stay tuned.

Behaviour

Apparently some members of a certain car group which I shall not say here think some of my responses in their forum in comparison or reference with what I've done to the SP to be boastful and offensive. My response to this is "Too Bad and I'm Outta Here!". I speak from experience so if you think this is offensive then my apologies but I'm not going to change my very direct style and way for your sake. This has been a good key learning so in future I'll be very very careful with the advice or response that I dish out especially in car group forums. Better to blabber around in my own blog..
