My new neighbor moved in and we got to talkin and he has a t66 that he was going to put on his older toyota supra and he is looking to sell it. I am going into uncharted territory in my skills here and i would really love it to do a single turbo smallblock i was thinking thow it on a 318 till it blows as im building a 360. I dunno what to look at or look for but he says it made like 600hp on the dyno but can anyone help me..Oh yea he wants 200 bucks really neeeds to seller....Its a precision..also says .68 i think ill look again..

As long as it is a Ptrim exhaust it will work fine for a mild 318.

How do i id a p trim??

For $200 for a PT66 if it looks ok and you can spin the shaft without it rubbing buy it and worry about whether it works for you later. You should be able to flip it no problem.

i talked to another kid i go to tech school with and he said play in the shaft is ok if its a ball bearing turbo as long as it dont rub, i checked it and it has some play and it doesnt rub so am i good??
