When you say 89 prelude I can safely assume high mileage. Unless you have a very stong bottom end (crank, pistons and rod) and fairly low mileage, I would not boost the engine. Alot of thought, money and time must go into the engine before just “slapping” on a turbo or any power adder for that matter. If you are not trying to hear me on this and add a turbo anyway, make sure you have a low boost setup. Approaching it conservatively might give a little time and fun with it.
Those guys above me are all right. If you wanna blow the car up, just strap on a nitrous bottle. It’ll be quicker, easier, and just as painfull for the motor.
It’s not the turbo itself that breaks the engine – it’s detonation caused by not enough fuel or the wrong spark timing. With a conservative amount of boost, you could probably keep it alive with larger injectors and good tuning (either on a modified Honda ECU or aftermarket engine management).
With a rising rate fuel regulator, made by Greddy ,and with some timing adjustments,you can get by with about 6 psi of boost, any more than that will crack the ring landings on the pistons. Just dont be in a hurry and double check evrything before the first run. and if possible use an intercooler,and a blow off valve instead of the waste gate.

Without the proper fuel upgrades i give it 9 minutes on boost.
yes unless you get bigger fuel injectors high pressure cylinder head and bigger pistons
