So i thought i'd write up a little review now that i've gotten the 4.785 final drive and ACT prolite flywheel. A little history first; the car just came up on 98,000 kilometres so i also changed ALL my fluids, and replaced the timing belt, water and oil pump, oil pickup gasket, oil pan gasket, front and rear main seals and got the valves adjusted.The clutch was not replaced because the original owner had it replaced on warranty about 30,000 km ago, not too long before i bought the car. Anyways, the first thing i noticed when i got the car back on the road was the flywheel. It felt quite a bit quicker dropping revs. Had to drive nice for the first little while, so i didn't notice the fd as much as i was hoping. Once i started driving and shifting more normally i noticed the fd alot more and the fw as well. I have to say the car just feels right now, as if the car should have come that way from the factory. Rpm's drop just right between shifts now, and downshifting is even better than it was before, just a quick blip and in. I have heard some compaints about having to rev more from a standing start with a lightened flywheel, but i actually found starting to be easier than before. Where i really noticed the difference in the combo was at the autocross. I've done 2 since the install and the car feels so much better out there it's not even funny. Where i needed to shift down into first in some areas previously i can pretty much stay in second and still accelerate pretty quickly. The car is just so much more willing to accelerate now. I would highly recommend this mod to anyone, as long as you don't mind the extra revs on the highway, which don't bother me.(you can actually pass fairly easily in 5th gear on the highway now too)

 

Good review...

 

Good review which clutch are you using, i'm going with the act streetlight /excedy and 5.0 FD

 

Good Review JDM FD ACT FW

 

try not to rely on downshifting to slow down..
that's a stress load on your valvetrain..especially now that the flywheel is lighter.

 

I thought there won't be a big stress load on the valvetrain as long as you rev match when downshifting?
Please correct me if I am wrong, thanks!

ya, I'd like to know too

btw, good review CanadianR

 

Thanks, sorry i haven't been on here for a while, just looked for the thread. I also believed that matching revs when downshifting would minimize drivetrain stress and wear. Someone tell me if we're wrong.

I'm using a stock Type R pressure plate and clutch disk, as they only have about 30 k kilometres on them. I'll probably upgrade to an ACT clutch in a couple years when this one is toast, probably just an organic-type disk as i don't really plan on ever exceeding 200 whp and want to keep a stock-like clutch engagement feel.

 

good review. sounds like great mods. downshifting without revmatching will wear out your DRIVETRAIN more, not really your valvetrain. only way you'll mess up your valvetrain while downshifting if you downshift to like 1st going 40 and go over redline. revmatching will greatly decrease the wear on your drivetrain as well but use your brakes more often too, especially in high speeds like 50+, unless youre autocrossing or road racing.
