Ive been there and done this. Heres my advice.

If you are d15b2, do the MPFI conversion. If your a Si this doesnt matter.

Piece together a good kit, not using EBAY MANIFOLDS, TURBOS or WASTEGATES!!

Convert to obd1 and run crome.

Even on a d15b2 with 7-9 psi you WILL walk all over b16s and GSR swapped hatches for MUCH less money. When i was running 9psi on my d15b2 it would wax b16s.

the key is getting a good tune and the motors can actually last for a while as long as you are conservative. If you get boost happy it will blow. Be reasonable and tune it well and it can still be reliable!

I ran turbo d16z6 for years, sold the stuff off it, put a b16a in my car and was uber pissed. they are ****ing slow. I sold the b16 off, rebuilt the d16z6 and now im about to re turbo it again. That should tell you something.

Go for it! Worst case scenario, as long as you plan parts out good, if you ever go b-series you will only be a few parts away from still having your turbo stuff work on it.
