Rebuilding a turbo is actually relatively easy if its side to side shaft play. Especially cause its a mitsubishi turbo. The main thing is marking them, they are balanced from the factory and if you do not align everything back up perfectly, youll grenade your turbo quite quickly. I know a few people who rebuild turbos if your interested, $100 to $200, that includes sodablasting everything, new oil plate, new gaskets, and new oil rings. I personally dont even have time for my own cars anymore so unfortunately I cant help you with it.
I do say leave it alone and drive...shut up RJ lol.
As for horsepower, I would suspect you make 180-200whp realistically. maybe 220whp if its perfectly tuned etc etc. The 15b is a SMALL turbo, so spool will be relatively quick on even a 1.6 liter honda motor.
An internal wastegate will be fine if you port it out a bit. Stock it will probably like to creep just a bit maybe up to 14-15lbs.
Y not just use a stock D16? A lot of people go crazy with builds which is the wrong way to do things. Throw it all on the stokc motor, and see how it goes. If you blow it up, you blow it up. Ive heard tons of stock d16s with headgaskets do 200whp. Rather blow up a stock d16, pick up a new one for 200 bucks and throw it back in there than ever deal with engine builds.
You could do a real budget build with that 15g, a 14b, or t25. With small modifications a dsm manifold bolts up to hondas, bolt on the turbo, tap the oil pan, tap the head, ive got tons of intercooler piping, use a stock DSM sidemount that you can pick up off a dsm board for like 10 bucks. Then throw hondata on it with stock turbo dsm 450cc injectors. And enjoy. I do not suggest a front mount for this setup, youll more likely get more pressure loss from the fmic than any benefits youll see at 12psi. I think 12-14psi would be great for that honda motor after looking at the compressor efficiency map. You wont make any more power over 14psi with that td04 hot side though.
