1988 supra. 350 v-8 engine swap? - Page 2

What about your guages how would you make the guages display what the new 350 and trany are doing, the guages run off the ECU dont they.

Using stock gauges probably won't work, due to differences in resistance values/wiring between gauges and sensors on the new motor. Would probably have to go with after market gauges that are wired independently. The ECU is only really needed with fuel injection/emissions controls, so if you're swapping in a carburetted 350, you're not gonna be able to pass emissions, and therefore don't need to worry about controlling them.

Unless you want to do your part in protecting the planet.
Then you should get a POS Prius.

i'd recommend a 1jzgte with r154 transmission and either a 3.73 lsd, 3.91 lsd, or 4.10 torsen. it will cost you no more than 6 grand

And I would suggest going auto. No clutch to mate up, the shifter wont end up in the wrong place, etc. Then all you have to do, is measure your driveshaft and take it to a good shop to get it chopped down and get a chevy U joint put on the end. And then with a carb you dont have to worry about computers, wires, fuel return lines, sensors, etc. Just a fuel line, a few vaccum hoses, and a battery wire. lol. I would love to put some sidedraft carbs on a 7mge. Yay for power.

Dude have you cracked open a Jegs or Summit catalog lately? There are tons of LS1 parts. Including a cab mani out there. Check out some of thr RX7 websites. Those guys do LS1 swaps all the time. Might help. Good luck.

Here are a few videos of my 1987 Toyota Supra MKIII 350 Chevy V8 700R4 Swap. It's easy to do and probably cheaper than a rebuild or modified Toy motor.
