i have a 91 hf all stock except for intake and exhaust....but what i need to know is...i just bought a 91 si motor, trans, basically everything that involves the motor(everything has 70k on it and motor was JUST rebuilt) and im going to put all these parts into my hf to replace the slow HF shyt. i want to do a little turbo to keep up with some cars until i do b16 in a couple yrs. how safe is it to do this(turbo) what kinda do you recomend? how much power? and how long will my motor last with this turbo on it? and what i should do to motor before i get turbo to make it last longer and run stronger?

 

before you go turbo, you should add Si front brakes(i think you have to anyway for a Si swap) and build up your suspension as well...junkyard turbo is becoming popular and you can safely do 6-8 intercooled psi...save your HF exhaust manifold because that is the turbo manifold for the junkyard turbo, with 6psi i think you can hit mid 14's...

 

well i bought a si from a friend...she crashed it so i have the whole car so i can get any part from it....but will this last long and how much for a junkyard turbo and what do i need to get?

 

well if its a 90-91 Si take the front and rear brake assemblies, brake master cylinder/proportioning valve, and then the engine, tranny, ecu, and get new axles as well as other tune up parts...

as far as the junkyard turbo, it will probably be around $1000 for all the parts, well you have the turbo manifold, just need to port it a lot, then you have to buy a turbo adapter ~100, then turbo, intercooler, oil lines, pipes, boost control, fuel management, etc...
