This turbo bolts directly to the facory downpipe so there are no modifications. Actually you only need an actuator and a Cobra intake and air filter. Get them from RPM.
The turbo blew due to oil starvation, which was due to the fact I had a clogged oil supply line, so please change your old oil line with a new one. I ended up buying a remote oil supply filter kit from RPM for 90 bucks after I bought another turbo. If you really want it I will give you the turbo for 250 plus 20 Shipping, thats a really good deal. Then you can rebuild it when you have time. Text me at the number in the original post. By the way its a damn good looking turbo.
Typically the tach would bounce when you crank or the. It over. Not sure any other reason why it would stop..? Check the wires to the coil. Some times with intercooler hoses mess up the top connector and wires . I had a black and silver 1992 typhoon like your little profile photo. Also a 1991 syclone.
