A T3 48/60 or 63/60 would be decent for that motor. Even a holset Hx/Hy 35 if you want to go ***** to the wall. Check the classifieds here and other Honda sites to find a decent manifold. If you can weld visit the sponsors and buy some dirt cheap mandrels for the charge/down piping. Engine management will be your biggest obstacle in this case. A chipped p30/p28 ecu would be your best bet if someone local to you can do the tuning. Definitely do some searching before asking questions though. the link below will give you an idea of how alot of people do it.

^^ Thanks That's a good link.

 

ROFL!!!

 

You can hit up ebay for some good deals on quality turbos such as garrett, holset, IHI, precision, etc. For the manifold I would suggest something cast, as it'll hold the abuse much better than the shitty SSAC tube ones, and you can still get away with using the cheaper cast chinese knock-off's. I never had too many issues with the chinese wastegates, but it's still a 50/50 chance that it'll work fine. The ching chong blow off valves will leak at higher psi's, but for low boost they'll be ok for a while. As for FMIC's, the chinese cores are nothing more than glorified bar and plate cheap radiator cores with end tanks welded on. They do a shitty job of cooling, but it's still better than nothing.

 

also. what size injectors shold he be running. iv heard dsm 450's are good but someone just told me they are to big.
he has b16. it will have walbro 255, FPR, chipped ECU, any suggestions?

also will he need the resistor box to use the dsm 450's. i know he will need the plug clips.

 

450s are good for up to 300 hp. You will also needed a wb, like this one https://www.homemadeturbo.com/forum/...?topic=89857.0
