Hello. I just tried to put a T2 (EVERYTHING, engine, tranny, rear end)) into my na 88 gtu. I come to find out that 1 rotor has 75 compression and 1 has 80. I pulled both the bottom spart plugs and turned her over to hear an uneven beat. This I Would think means that it is bad correct? I cant get it to idle correctly after trying everything.

Anyways, I just want to throw my NA motor in there for now cause I need a working car. Anything special I will need to do? I have the NA flywheel and clutch. Is that where the switch between the two will happen is at the flywheel? Will I need to use the NA flywheel and clutch or what?

Thanks.

 

your goin to need the clutch and flywheel for the n/a but other then that theres no problem.

 

You will need the Turbo clutch and flywheel, not the NA ones. You always match the clutch/flywheel to the tranny. Other than that, you just drop it in.
Also, uneven pulses definately mean its a bad engine.

 

Match the flywheel and clutch first to the series(S4, S5), then to the trans(turbo, N/A).

 

yea meant turbo clutch and flywheel. long day today.

 

well ... weirdly the car came back 2 life. (the turbo motor) I turned the bac screw all the way out and then turned the idle screw in the back of the motor up hella. The car idled and I almost died. It was a 2500 rpm idle but it was an idle. I slowly dropped the idle screw down little by little, till now I have a 1000 rpm idle.

Its weird though, I hit the gas, and it revs up after a little bit of hesitation, but when the rpms drop back down, it goes to 500, then bounces up to 1000 and back down to 500 a couple times, backfires, and then goes back to holding idle at 1000. Any ideas?

(PS. im going to post this somewhere else, but im saying this because I think I can keep the t2 motor for a little while!!) THANKS guys for the help, if I Cant get the t2 to be stable, I will know what to do to put in the NA back in. (THANKS!)

 

Do a compression check to be sure. You can get them to run even one one rotor.

 

If he can get it running well and it pulls hard it's safe to say it isn't blown...
