350hp
 

I just bought a 1990 MK3 Supra and I was wondering the best way to get to 350hp... I have the non-turbo 7M-GE engine. Hope yall can help me out thanks

turbo = only way

yeah turbo is the only way to feasibly get that much power... i realize that after researching it for hours... i have a 7mge also and was wanting more power, just gonna do a stock rebuild for now

yup, it is possible to build a "7M-GE(T)" but to be honest by the time you've faffed round with building and setup and crap you may as well just fit a full on GTE setup... although the GE bottom end is identical just needs turbo oil feed/return opening so if yours is known good with perfect hot oil pressure etc. and you can get hold of a knocking GTE engine plus ECU, loom, intercooler/piping you could do it that way...

There are two significant differences in the bottom end that you forgot.

1) the GE runs a higher compression ratio which isn't safe (at least not with cast pistons) on a turbo setup

2) the GTE uses oil squirters to help cool the pistons (this REALLY helps ensure a longer life with cast pistons).

I've turbo'd a GE and it is far from a good choice.

So if I do an engine swap I will also have to swap the transmission? In that case why not go for the 1JZ or 2JZ?

No the auto and manual both bolt to a 7m motor.

Ok
 

So my w58will bolt right on to a 7m-gte?

No. Different flywheel, clutch, transmission mount and driveshaft. The differential is also different depending on the year of the car... I've posed all of this in the past three days, look through the forum a bit, you're asking NOTHING new. EDIT: You can swap over all these parts though... naturally.


As for why no do a 1JZ or 2JZ? They're still a lot more effort and money and the 7M is still a good engine.
