New here had a few ?s 88 7m-ge

[PayMeCracka]

I currently own a 2000 gt mustang that i ahve to sell due to work. My buddy has a 88 non-turbo automatic supra i can pick up for $500 it needs a new maf cats and a few wiring things. I was wondering is there much you can do to these cars and is there anything i should be aware of or know when purchasing this car. Do they have common problems and where is a good place to get parts thank you.

There have been a few threads of late on the subject of what to look out for. Take a quick skip through the threads for more information than you should need.

That said, the non turbo models are pretty limited. Sure you can squeeze a little more out of em, but before very long you'll miss the power the GT had and want to go turbo to get back into that playing field. If you can get it for a song and for a few bucks get a running car, it will prove a comfy and somehwat sporty ride still

if things work out ill get the car and tag it historic i have a buddy who has a stock turbo kit off of his 88 before he did his 1jz swap but i know ith higher compression there are issues and i dont know the tuning options that well for these cars. ive had hondas mitsu ford and chevy but never really looked into tuning or in depth info on th aspects of bottom end and what not of the inline in a toyo

you can do an NA-T swap, it's all gravy, just use the 7MGTE electronics, you can even use the wiring harness, it's mainly plug and play..

[PayMeCracka]

ok now is it safe to run the turbo on the na motor being that it has higher compression and by electronics do u mean just the ecu and harness or is there more i need from the turbo car

[Jeeves]

The turbo car has more knock sensors, a different ecu, oil squirters in the engine to cool and lubricate the pistons and as you mentioned the GTE engines are lower compression from the start. Combine the higher compression, higher temps and boost and you've got a recipe for more detonation that is likely leading you towards head gasket problems.

ok and i have one last question is it possible to do a 2jz swap into the mk111 and if so whats all involved

[Razo-E]

yes it's possible, if you have (but you dont) a late 89-92, it'll drop right in, minus a bit of hammering of the firewall on the passenger side for the 2nd turbo...

now getting it to run is a whole other issue. Be prepared to spend upwards of $8000 on the swap and that's if you do it yourself, which you won't...

[PayMeCracka]

I would b doing the swap myself ive done multiple swaps on cars. and y would it only b able to go into the 89 and newer and not the 88? they both from the factory have the same motor options. and if this is not possible then what motor swaps can b preformed on the 88

[Razo-E]

late 89's received new cross members and different motor mounts that are 1JZ compatible, as the 1JZ was introduced in japan at the time...

there are JZ conversion mounts for sale here www.bicperformance.com

Weird. I swear I typed in a response here yesterday.
While it's essentially the same lineage there was a pretty decent change in the car itself in 1989. The body style changed pretty decently between 1988 and 1989 and there were some pretty hefty changes regarding the crucial systems as well.

The ECU's are different as are some of the electronics and the wiring harnesses. The engine crossmember (as Razo mentioned) was the piece that really changed that makes dropping the #JZ engines into the earlier model Mk3's tricky.

-'89: transitional year from the "old" to the "new". fascia, side mirrors, spoiler, fog lights, tail lights, moulding (plastic vs. <'88 metal backed), back of vanity mirrors (cloth vs. <'88's vinyl), cloth interior pattern, rear shoulder belts added, ECU, TPS angle (90 degrees diff from the <'88 and throttle body changed to accomodate different TPS (idle bypass screw also removed), climate control, gauges (160 MPH speedo, less deliniations), steering wheel and radio all changed. dual cup holders added to inside of console lid. power recline added to driver's seat. 6 speaker stereo added, no more Super Monitor option, no more headlight washers (US only). Emergency brake and shifter boots changed to black. turbo models got a 3.73 differential ratio, addtional strengthening was added to all rear subframe. smaller TEMS actuators (faster?). TEMS no longer standard on turbo models. progressive power steering added. fully counter-balanced crank added (7M crank vs. older 6M crank), redline lowered accordingly, engine mounts changed to softer and larger rubber, fuel feed hardline changed to accomodate different engine mounts.

ok so first off my buddy screwed up the car is actually a 89 built , the dash is split the car shifts fine, the power steering rack is leaking, im pretty sure the brake booster is bad it needs and afm, some wirinf and sensors, and then the vacuum lines are over the place i took some pics on my fone but idk how well they will turn out

[Razo-E]

89? Even better, check the motor mounts, if they are square it is an early 89, if it has round mounts, it has the JZ compatible mounts and should be easier to swap in...

[PayMeCracka]

it was built in 03/89 the rubber style part of the mounts are round. Does anyone know where i can get a dash for this car or how to repair the existing dash. the interior has all the typical wears and cracks. Im pretty sure the ac doesnt work and as for the power steering i wont know that till we put the belt back on. for now i want to get the car driveable for every day untill i save the money to do the swap.

[Jeeves]

It's still not an easy swap by any means and it's very expensive. Unless you're talking about the 1JZ, those are pretty cheap and not too hard.
