Cressida VS Supra

[PorterzSupra]

Why is the Cressida rated at 190 HP and the Supra 200 HP ?
If they are the same exact motor somethings gotta be different here, you dont loose 10 HP and 8 ft-lbs just because the motor is in a different body. What is the difference?

supra is 230 btw but im geussing cus of the different exhaust setups on each. minor changes in intake and exhaust piping can make that small difference. not sure but do they have the same ecu's?? if not then theres a big factor aswell.

^Hes probably talking about the 7mge. ^
But yea, anything from exhaust and intake to timing and emissions systems (which is why JDM 7mgte's have a little more power). I dont know what the specific difference is between the cressida and supra though

whoa whoa whoa, the cressida has a 7M?

 

[GrimJack]

Yes, the Cressida comes with a 7M-GE.

Toyota does this a lot. It's more than likely changes in the timing/fuel map of the ECU.
The Supra 7MGE ECU was for a sports car while the Cressida ECU was for a family sedan.

One example I really remember is the 94-99 Celica(I owned a 95 ST for over 5 years before I got the Supra).
The 94-95 7AFE had 115hp while the 96+ 7AFE only had 105hp. The changes were all in the ECU.
There was a minor body change, ODBII was added, and timing/fuel maps were changed to provide better fuel economy(which I don't see as I was getting 34 MPG city with exhaust/intake/plugs+wires/adjusted timing).

Lol... Search: TVIS.
You know how the Supra's 7M-GE has that funky Y-Pipe between the TB and Intake Mani?
Ya, well the Cressy's 7M doesn't have that.
kthxbye.

Isn't the Cressida 7M's intake manifold different?

 

[NDBoost]

cool i just found a 7M 88 cressida for $500 it runs rough but has new rebuilt trans but no rear window. Im thinking about buying it

 

[koulee]

Isn't the Cressida 7M's intake manifold different?

I think the cressida's manifold is the same as the 7mgte manifold.

 

[supra90turbo]

Isn't the Cressida 7M's intake manifold different?

Yep. It doesn't have that extra butterfly in it. It's more like a Turbo's intake mani.

 

[IJ.]

That could be the 10 hp difference right there!

 

[OneJoeZee]

does that mean that turbo cars would benefit from using the Na manifold?

TJ: Not sure if it would still work the same as the ASICs stuff might not work under positive pressure!

10 hp is only a small adjustment of the boost controller away anyway

 

[supra90turbo]

This has been discussed before elsewhere, but I can't remember....
I also can't remember the outcome... damnit...

The whole idea of implementing ASICs on the 7MGE was to give it a good torque curve, while also being able to retain a respectable HP output as well.

I would rather not try to put it on a 7MGTE, and worry about turning up the boost instead, as Ian said.

 

[OneJoeZee]

interesting...

ian, totally understand the boost control part. but you know its always better to make more power at less or equal boost if possible. but i guess this wouldnt be a good example of that type of mod, no?

 

[supra90turbo]

No, not exactly, Joe. But close.

 

[Dirgle]

This has been discussed before elsewhere, but I can't remember....

Correct, Jong over on SF discussed it great detail.

 

[supra90turbo]

here it is!

TJ: If there was a simple way to make it work correctly yes I'd agree.

I just see it as an added layer of complexity on a GTE as the gains just wouldn't be worth the effort.
