flywheels

well, here is the deal, the 4G63 6 bolt flywheel will fit the 4G64 6 bolt as well as the 7 bolts will all interchange, hell the EVO 4/9 7 bolt will fit the 4G63 narrow block, so you can swap and choose all over the place

BUT I am a big advocate of proper balance on the crankshaft

now the wide block R 154 I built re uesd the G54 b flywheel, there were two built for the G54b, I used the one that used a larger clutch

BUT I dont know if the flyweel for G54b is balanced to be used on the 4G64 crankshaft

IF I could build the wide block 4G64 and used the small FWD or AWD 4G63 flywheel I would because it would make it easier for me but because it fits does not mean it will balance properly
do you have part numbers to sort through that can help us choose?

there is a lot to think about, first off what if a guy is destorking the 4G64 with a 2,0 crank?, then you may want the AWD ( 270mm diameter ) flywheel
BUT if you are running the stock 4G64 crank with the stock G54b wide block flywheel, then you need a completely different housing

I like the idea of the AWD flywheel with the destroked motor and using longer rods

On a side note:
Got any 2JZ adapters made up since your mill is back up and running.

I just got all my numbers back for all my other transmissions, now I am working with the T 56 data.

I'm going to throw this out there but don't shoot me if I sound like an idiot. As I understand it you have already built a t56 housing for the narrow block 4g63 buys and they tended to use the AWD flywheel since it was smaller. Since the 4g63 and the 4g64 use the same parts, why not keep things simple and just build the wideblock housing the same?

Wouldn't this be the easiest for you and us since people have already been running this and 4g63 AWD OEM and aftermarket options are plentiful?

where is the 'death factor' in that?
