The B18C5? You'd be better off with a B18C1 (GSR motor) because of the lower compression, and the head is more boost friendly. But if the type-r engine is the one you have then I'd recommend upgrading to at least a Hondata S100 ECU, and upgrading your fuel system (440cc injectors maybe for 10 psi?), and if you change internals then change the pistons for lower compression pistons. Everything else in that motor should be reliable for boost. Definetely stick with the B18c5 transmission! You'll have much more fun with the gearing in that than any other trans. (It'll handle the boost fine too, just upgrade your clutch if needed)btw, lucky guy if you have that engine (B18C5) I'm pretty jealous.

Do you already have the engine? If not, I'd go with something else. But if you do have it, you should be fine for up to 10psi. The ITR cams make great power with little overlap on boosted B series VTEC engines. The only obvious things I would recomend would be bumping up the injectors to 440cc, possibly the fuel pump, a good exhaust at least 2.5", and tunning. Leave the tranny as is. The hondata S300 with boost option would be great.
