Im looking to turbo my 1992 GSR that has 110 000 KM. It's completely stock except for an intake and suspension. What im wondering is what do i need to do to the engine to support a turbo. Im thinking of boosting around 6-10 PSI. Will a 2.25" exhaust be to small?

thanks for the help

 

IMO, yes... 2.25" is too small.

Go with at least a 2.5" exhaust, though I like to see 3" exhausts on turbo cars, and make sure you have enough fuel, and some kind of management for it.

 

another option for you is to get an e-cutout, so you can keep your existing exhaust and have free flow when you want it. Do a search for e-cutout.

 

at least 2.5 inch I would say also... if you can fit 3inch thats better yet.

e-cutout seems to be a good solution.

 

where would the best place be to start with this turbo project? I want to make sure that the engine doesn't blow since this is my daily driver. Ive also heard that 3" would not be needed, I really don't want a loud car. My buddy already sets off car alarms when he drops me off in his car and i hate it.
