Reacently did an engine conversion on my mitsubishi l200 pickup ,fitting a j spec tt engine and auto box ,problem is the extra weight is wrecking auto boxes ,last week I took the box out and tried to fit a mk3 manual turbo box but the flywheel dosnt bolt up to the crank and the mk4 clutch dosnt fit on the splines of the mk3 box so just wondering if anyone knows how I can get round this problem

 

check out the vid on youtube l2oo twinturbo

:D I put a link up for that vid a while back. Nice one! The MKiii Supra R154 5 speed box does mate up to the 2JZ, but I believe you have to use some of the parts from a Mkiv, bell housing, flywheel ect. There's plenty more info if you do a search. ;)

The box mates up to the block no problem ,its a 1jz flywheel I have, it haz 6 bolt holes rather than 8 like the tt ,and if I manage to get the tt flywheel will the 1jz clutch bolt onto the new flywheel ?,the other thing I was thinking of doing was using the tt presure plate and the 1jz friction plate but aparantly the presures are diffrent ,theres a lot of posts about this topic but I cnt find exactly what im looking for

 

ps anyone have a tt flywheel ????

you need:

 

jzz30 manual bellhousing(this mates r154 to jz series engines).

The 1jz flywheel has 8 bolts, not 6. The 7M series engines have 6 bolts. I just bought a complete ORC kit including flywheel to save the bother(and take the power). Plus, there was a horror story on the oz site about a pressure plate or flywheel ripping through the bellhousing and almost taking a guys legs off. This was from mixing and matching.

 

good luck bud:)

Defo a 1jzgte engine with a 6 bolt flywheel mate, and the gearbox from that engine bolts directly on to the 2jzgte engine, spoke to jezz today and think we have it sorted, we will see when the parts arrive
