How far can you push a 7MGE on turbo?

Turbotuner2.3 · 10-26-2007, 08:11 PM

what size injectors are in the 7MGE & 7MGTE, i couldnt find that in the shop manual's I have... obviously thats pretty important

as for the compression, is the only difference the pistons that they used for the different compression ratios? I was wondering if they had difference in the combustion chamber of the head as well, but maybe not...

I'm going to try talking the kid into getting a 7MGTE to swap in...

Or I guess i'm going to do some searching on the best ways to lower the compression in these engines...

The 7M-GE has 330 injectors I think, but the stock 7M-GTE injectors are 440s.

I'm pretty sure both the GE and GTE are the same excluding turbo oil retern and feed and compression ratio.

To lower compression a small amount you can get a thick metal head gasket.

one big thing i really need to know is what flange does the stock 7MGTE turbo have? is it a T3, T4 , or some other size flange?

I'm not sure, but If you know the dimensions I could tell you, I have a CT-26 sitting near me.

The flange on the CT-26 is ~4 1/8 X ~3 3/4, hope that helps, I think its a t4.
