Supra to Cressida Swap

[Spektyr]

I am the proud owner of a 1989 Toyota Cressida (stock for now), and I was about to purchase a 1989 Toyota Supra for $300 as strickly a parts car.

Now, I was wondering if the:

• Cams (More aggressive profile)
• Heads (better valve management and stronger valves)
• Exhaust Manifold (better flow)
• Brake Rotors (bigger brakes, 5 lug instead of 4, and 4 Wheel disc)
• Brake Calipers (to go with the bigger brakes)
• Rear Axle (to handle the possible GZE or GTE upgrade)
• Sterring Wheel (cause it looks better *laughs.*)
• Seats (I have always loved the Supra Seats.)
• Computer (Sportier Engine Management)
• And possibly Pistons (better compression)

would transfer from the Supra to the Cressida. Both have the 7M-GE powerplant, so I figured the Supra would have the more sportier designs for the parts than the ones on the Cressida.

If anyone can help me in selecting the proper parts to swap over, please, let me know.

And the reason I don't just drive the Supra is because it is tore up. There is massive body damage, and the rest of the interior is shot. I would have to buy a whole new '89 Supra with no motor to make the Supra I am looking to buy look nice.

Thanks for your time, and hope to hear from someone soon.

Also, as a side note, does anyone know of a good Powdercoater out in OC/LA region? The Supra is sitting on demolished 18's and I was looking to get them refinished.

It's the exact same powerplant.

A 7M-GE is a 7M-GE is a 7M-GE.

If you're going to swap in a GTE, it's another story.

Brake Rotors (bigger brakes, 5 lug instead of 4, and 4 Wheel disc)
Brake Calipers (to go with the bigger brakes)
Rear Axle (to handle the possible GZE or GTE upgrade)
Sterring Wheel (cause it looks better *laughs.*)
Seats (I have always loved the Supra Seats.)

Those I don't know about.

Thank you Jeeves for your propmt response. Guess I will have to experiment and see what needs to be fabricated.

[Jeeves]

Good luck. In all honesty, I'd suggest a 7M-GTE conversion. With the power of the turbocharged variant of the 7M, the Cressida becomes an awesome sleeper. Got one in town > 400rwhp.

[Spektyr]

Oh, I have been thinkin' about the conversion. At first, I was goin' to go to the old scrap heap, and get all the piping, turbo, intercooler, etc. for about $150 and do the work myself. $450 later, I would have disc all around, stiffer suspension, and a turbo charged Sedan. Then my friend told me of this contact he has in Austrlia that can get Japanese Clips for cheap.So he is goin' to talk to him about getting me a Chaser front clip with the 7M-GZE motor, although I am wondering if I would still be able to turbocharge the supercharged motor? Power boost through the entire rev limit. He he he. If not, I'll just go get the GTE front clip, and swap the steering wheel over to the other side as well.

Also, the lamps of a Chaser would be the same as a Cressida, right? Got an all white Cressida, with horrid yellow and red turn and tail lamps, and I am lookin' at Chaser clears.

[Jeeves]

There was never a production model 7M-GZE. The chaser had a 7M-GTE just like the rest of us.

Headlights:
To me, it's doubtful they'll fit here's why:
Car ----- Body Style
Chaser - JZX??? Style
Cressida - MX?? Style
The cars are of different body styles. They could work, I wouldn't know, I've never checked or tried. However, the body codes don't match so it's doubtful in my mind.

[Spektyr]

You are a fount of knowledge! Which is a good thing for all us here. *laughs.* Scary to the rest of the world, but good for us.

I have seen some cars on the 'net with claimed 7M-GZE's which would be a super charger (can't place the guys image, but there is one at Car Domain.com), so I was stoked. But, I would take your word over theirs anyday (has read up on a lot of the posts here, and you know your shiznit.) So, looks like I am off to the junk yard to go get my turbo kit.

Thanks Jeeves.

[Jeeves]

Np. Yeah, if you search for 7M-GZE on google, the first link that shows up is the one for this forum on the discussion we had on it last time. All I can tell you offhand, is that that one on Cardomain.com, is NOT factory. It's also never been heard of/seen again.

Good luck, keep us updated.

7M-GZE? No such animal. Not worth it if you're fabbing it up yourself.

As stated, all 7M-GE's in the Supra/Cress would be about the same.

Headlights (and taillights, for that matter) will NOT interchange. The Chaser did NOT come with a 7M-GTE. 1G-GTE or (later on) 1JZ-GTE were the turbo powerplants of the GX80/JZX81 cars. The only body part that you can share is a Mark II's (non "bus-stop bench") rear bumper, I don't know much about this one, but you may need additional hardware.

If you're putting in the 7M-GTE (and not turboing your 7M-GE), you will need to swap over your oilpan/sump/pump, etc. Cressida is front sump, Supra is mid-sump.

JDM 7M-GTE motors will come from Soarers (also mid-sump, I believe) or Supras.

Jeeves had it pretty much covered.



I urge you to head on over to http://www.toyotacressida.com and don't forget the forums. I stress that you should search the forums, as well. Lots to know.

Hmm.. maybe I should put the spare 2JZ-GE in a Cressida....

[Jeeves]

7M-GTE (by the numbers) puts out more power from the factory than the N/A 2JZ block...

2JZ-GE:
220hp @ 5,800 rpm
210ft-lbs @ 4,800 rpm

7M-GTE:
232hp @ 5,600 rpm
254ft-lbs @ 3,200 rpm

[repinS]

I'd only put a 2JZ-GE into an MX73 ('85-'88) Cressida, considering that it's a healthy ~50 crank hp increase over the stock 156 from the 5M-GE. Accompanied by a 5-speed swap, of course. Make it a wagon, too, if at all possible.

[mkivsoopra]

Yeah, I'm aware that the 7M-GTE makes more power than the 2JZ-GE. It's just that I'm going to have a spare complete 2JZ-GE laying around when I finish the other swap.

[Jeeves]

Valid point.

You can get a 7m-gte engine for right around 1000 dollars guaranteed to have less than 40,000 miles on it. I was going to do the exact same thing when I came back from Iraq the first time. But gophers totalled my car be eating all the wiring. Now you guys gotta remember, the difference between the 7m-ge and 7m-gte isnt that the gte has turbos. It actually does have strengthed internals. So whereas the gte block could safely handle 300 hp, the 7m-ge block could not. So even if you wanted to throw a turbo kit on it, you would only be able to go so far before you had to change out the crank, pistons and rods.

So just get the 7m-gte and throw it in. Your axles and driveshaft should be fine, youll have to replace the clutch, your transmission might be fine. Youll definately have to get a performance radiator. Plus just because a car uses the same engine doesnt mean it uses the same ecu. I tried to buy a turbo kit for my 03 matrix when a turbo kit came out for 03 celica gt-s' but I didnt take it because they said that while it works for the celica, it doesnt work with the matrix electronics.
