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?

[americanjebus]

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.

[socc924]

^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

[NDBoost]

whoa whoa whoa, the cressida has a 7M?

[GrimJack]

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

[aaronc222]

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.

[IJ.]

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?

[IJ.]

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.

Correct, Jong over on SF discussed it great detail.

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.

[Push]

Cressidas are slow don't buy one ;)

[Nick M]

If you look up the part numbers for the camshafts, that might help too. The intake does not have ACIS, that is correct. And a more restrictive exhaust.

[Toycoma]

yeah, cressidas suck. dont buy one. ps the 7mge is in the 89-92 cressida. so unless someone swapped one into the 88 cressida you found for 500 bucks, it not a 7m.

the GTE was available from 87-92, and according to the owner it does have a inline 6cyl thats "popular". Even if it wasnt the 7M it would be the 5M motor inthe cressida which still isnt a bad motor, i liked how it felt in a mk2 and its even more simple then the ever so famous 7M.

and explain to me why cressida's suck as a DD, state some facts. I need a car that will get me from A to B while my supra is down for a rebuild, after that the cressida will get parked :) honestly i dont care about features or luxury, i want something that goes from a to b without rod knock or a bhg :) I only need it for like 30 days lol

i want a dual carb M motor :(

but the 7mge was only in the 89 - 92 cressida. 89 is the year the cressida chassis changed. mx73 is up to 88 and mx83 is 89 -92.

this thread is FULL of misinformation. people, if you dont know, DONT POST!

JDM motors do NOT have more power than USDM motors. the AICS system is discussed in great detail over on www.mkiiitech.com

i believe that dr. jonez had the N/A intake manifold on one of his cars, and decided it's not worth the "gains." (maybe it was dean marcum?)

anyway...

[cruzinbill]

7mge's come in cressidas from 87 up to 92, by the way they dont suck they are just as quick as a na supra so if you turbo it wich is easy since it has a turbo intake already, it is quite easy.
Cressidas also share alot of suspension componets with the supra, cant remember all so i wont post those but search its there.
So really if you turbo a cressida wich is just as easy as turboing a NA supra it make a great sleeper and drifter.

no, the 7mge comes in the 89 - 92 cressida not 87. 87 is the mx73 chassis and has a 5mge. www.toyotacressida.met I also know a guy who has an 87 MX73 cressida and threw two rods through the block. It was a 5mge. check out www.toyotacressida.met if you don't believe me. and the mx83 cressida shares no suspension parts with the MK III supra. the rears are similar but the front is totally diffrent. the MX73 and MX83 share the same type of front suspension which is the same on the MK II from my understanding. not sure if the mx73 shares identical or similar rear suspension as the MK II supra though.

It was Dean. He said the system didnt work correctly. The vaccum resevoir probably doesnt function right under positive pressure. You would need a one way valve fabricated, then it would be worth it.

The MX83 has struts, the MA70 has SLA suspension. The cars are similar, but not shared platforms.


by the way they dont suck they are just as quick as a na supra so So two cars that weigh nearly the same but one has a tall 4 speed and 3.91 rear against a shorter 5 speed and 4.30 rear acclerate the same huh?:nuts:

[IJ.]

Nick: The Vac Tank has a 1 way built in.
(I use one on my car to help the Cruise Control out a bit when it's on boost up hills)

[lagged]

drjonez experimented with this also, i clearly remember seeing pictures of his brown car with the NA intake setup. i remember reading somewhere that it MIGHT be worth it if you got on a dyno and could control when the butterfly opened.

[Nick M]

I dont believe positive pressure was ever intended with the vaccum switching valve. I believe it could work with stand alone control, but those are all for the GTE that I have seen. Perhaps a solenoid?
