hey all,
just bought a jdm engine and fidanza flywheel soon to be installed in my se-r. the one question i have is that the flywheel doesnt seem to be big enough to fit on the crank, its a tight squeeze...is this normal? and if it is, how do i go about installing it? heat it up before i put it on? thanks for your help in advance.

I had to bake mine in my oven (my wife wasn't too happy about that lol) to expand it to fit over the crank per Fidanza's instructions.

I dont know if its different with B13's, but on my B14 the guy just threw it on when we did a clutch swap.

when i got mine from tony larocca there werent any instructions like that....but you did have to heat it up? ok cool, thank you!!

on my b13 i did it myself and it just went right one as good as the stock one (but aloooooooooot lighter)

You didn't have to hollow oout the holes to 11mm? I always thought the FWD SR20de flywheels were 10mm bolts while the det used 11mm. Therefore you need to get it drilled and balanced. Correct me if I'm wrong as I haven't gotten there yet.

Only on the GTiR.

paNX2K&SE-R, how hot did you heat the flywheel to? what temp in the oven?

I had to do it like 3 times because it cooled down too fast and wouldn't want to go on. I started at 350* and I ended up using like 500* in the end I think. I had my buddy hand it out the kitchen window and I ran it straight into the garage and popped it on and screwed 2 of the bolts in as fast as I could. Its been on for 33k miles with no problem. I have no idea how I will remove it if I ever need to though lol :)

I filed the edge of mine to a slight taper, then carefully drew it on with the bolts. It went on nicely.

another option i have besides heating it up and putting it on is to have a machine shop take a little off the inner diameter of the flywheel, a guy my dad works with offered to take 2/1000ths off. this seems safer and more reliable to me than heating it up, plus ill be able to take it off if i ever have to. what do you guys think?

any suggestions?

You'll need a bigger oven! LOL

ok, so i measured it again and the interference is about 1/1000, so im just gonna try the oven method. wish me luck!!

Use nice *THICK* hotpads. Trust me... :)

flywheel is on the engine...heated it at 350* for about 15 minutes and it fit on fine. The only problem i ran into was trying to line the holes in the flywheel to the holes in the crankshaft before it cooled down again. Thanks for the ideas and info.

Not to jack you guys post, but I just had the Fidanza flywheel and a Clutch Masters Stage 1 put on my JDM motor and I had no problems.....As soon as I break them I know I'm gonna enjoy myself!!!
