Engine Swap With Flywheel Issues PLEASE HELP

[bighauns]

Hey guys...

I dont usually post on this site, I use some others and it is hard to keep up, but I really need some help...

I am just pasting the following thread from my friend who is helping me with my swap. Please help me out on this one

I am doing a 4G63 engine swap for a friend now in his 94 Talon Tsi FWD and I found him a 4G63 AWD from japan and I ran into a problem. The problem is that the flyweeels are diffrent in size. I was going to swap them over and just use the USDM one but the crank bolt pattern is different. The JDM one has 6 bolts and the USDM one has 7. I didnt realize this till I finished the swap and realized that the starter wont mesh with the flywheel. The USDM tranie is a FWD and wont work with the JDM engine. I was wondering if you can get a 6 bolt flywheel that is the same size as the USDM which is 7 bolts and larger in diameter which is 11 1/8 on the teeth. Any help will be awsome. Or if I cant get that flywheel can I just use the AWD tranie and just not use the transfer case so I will just use it as FWD?

It has been nearly 5 months since I have drove my car and now this was the first time it was gonna be started up, but an issue arrises again...Please let me know what I can do.

Thanks in advance, I appreciate it!

It has nothing to do with JDM and USDM, they both have the same flywheels, the difference here is that there are two different motors, the 6-bolt motor is from a 90-early 92 car, a 7-bolt motor is for a late92-94 car, so first of all, you have the wrong motor for this car. HOWEVER, the 6-bolt engine is MUCH better and you can swap it into a car with a 7bolt motor relatively easily. You only need to make a few small changes.

Search on the forums about it.

Sounds to me like you got a 6 bolt awd motor from japan to put into a 7 bolt fwd. You'll need to get a 6 bolt fwd flywheel for your buddy and then everything will work out just fine. The problem isn't in the fact that they're different motors, but that one's a fwd and the other an awd.

Exactly. Good time to upgrade to one of those light-weight flywheels too! I made the same mistake when my friend and I bolted up my 6bolt.

thanks

Well you can pick up an aftermarket one from many of the vendors on this site. ACT and Fidanza are the most common upgraded flywheels. I have an ACT Streelite and I love it. The other option would be to just pick up a used one from the classifieds here or www.dsmtrader.com. Either way will work depending on your budget.

what is your suggestion? i really dont have any money for this seeing as it was kind of unexpected.

Well the cheaper route would be to get a used stock 6bolt FWD flywheel. Then you'll have to have it machined. So figure 50-100 bucks all said and done. An aftermarket would cost a bit more...

Thats where I got mine. Seems to be $228.74, so a bit more.
