Power Enterprise Super Strong II Timing Belt

For those who are running 'big' cams with aggresive lift ramp profiles should consider getting an upgraded timing belt. The stock timing belt has been known to fail in less than 30,000km if thrashed regularly on big race profile cams. With this in mind I did some research and discovered that Power Enterprise in Japan do make such a belt for the 4G93. Actually the timing belt is meant for the CA4A Mirage Mivec with the 4G92G MIVEC engine but lucky me that both the 4G93 DOHC and the 4G92 MIVEC engine both share the same timing belt. The Mitsu/Proton oem part number for this belt is MD176389 while the Power Enterprise part number is BM121. If you have the 4G93 SOHC engine or 4G93 with MIVEC head transplant this timing belt will not fit.

The Power Enterprise Super Strong II timing belt was developed in 1997 and has been used by many race winning teams. This timing belt features Kevlar and Nylon fibre for the tooth fabric over high efficiency rubber cord and has a durability 2.6 times over the conventional timing belt. I got my timing belt from M Power speedshop in Penang. The same belt can also be found in many other speed shops including N1 Racing, KSP Power, etc. Picture below of the package.

Installation should be done by a trained professional and was done by my regular mech. The whole job took about 3 hours total. Also took the opportunity to replace all related seals and bearings. Picture of finished installation. My adjustable cam pulleys are Z. Speed aka Skunk2 if you wanna know. The pulleys are machined from 6061 aluminium alloy and hard anodized. Smurf Blue over Red really stands out don't you think? Shame everything's under my carbon timing belt cover..
