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!

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.
