    I am reinstalling my turbo today. I have a softline kit arz/driftmotion. Do the fittings need any thread sealant or anything on them, or just screw them on? Not familiar with them no instructions in the kit or on the website.

(yes I did all of the priming) After idling for 5min checking for leaks I found it leaking oil out of the oil pipe where it comes off the turbo. It had a new gasket on it. It was torqued per tsrm. Should I still...

    shifter bushing r154

    Are the shifter bushings different between the r154 and w58. I replaced my crusty bushing in my 88 n/a with the green one and it made it shift really nice. On my 90 gte the r154 just had the thin black flat one in there. I stuck a green one in it and it was way too tight and didnt feel right.

    I recently bought a nice 90 turbo supra. The kid I bought it from didnt know much about it except the turbo went bad on him after a couple weeks and the turbo was bypassed. He wasnt a supra guy. I removed the turbo and the only thing I found that was done was the oil pipe was removed and a...

    MKIII towing

    Whats the smallest vehicle youve used to tow a supra. Last time I was able to borrow a truck. This time I may have to use my cherokee, which has the power but suprisingly weighs almost 500lbs less than a mkIII. might need to tow one 140mi. no problem?

    starter, alternator, or battery issue

    My 88 n/a doesnt seem to have enough juice to engage the starter. I can jump start it with my jeep. I had the guy at the auto parts store run some test on the car while sitting in the parking lot. It said everything bat, alt, start was ok. IMO the alternator may not be charging enough. Or the...
