is therer a turbo system or setup out there that you can run on a 91 dx hb and still run ac and the d15 motor? If so, please post for me even if it is your guarded secret, please!!!! want to turbo d15 in my hatch for originality and power, but still want comfort of ac all the way down here in hot tropical HAWAII... Please, pretty please, PEACE.

 

It is possible but all depends on the size of downpipe and turbo manifold you want to run. What are your power goals? If you just want a basic bolt on kit most I know of will fit. If you want a 3" downpipe that usually involves removing the A/C, as does running some of the nicer manifolds.

 

Oops, didn't notice you wanted to run the D15 motor with it... not familiar enough with that motor to be sure. If you just wanted mild boost I'd recommend a ZC swap, simple and will probably save time and your engine
