300whp is prolly the tops for an average build on this motor. A log mani will support 350ish to the wheels. You wont need a large hot side since there is just no displacement or high revving. Smaller hot side with a decent sized compressor will work nice for response and top end :)

i'm sorry but how does boost doesn't hurt a motor? if the internals are too weak to support the explosion/extra volume in the cylinders they will bend/break.

also you are correct about the bigger turbine not being needed. for the full built engine i'm thinking of using a Garrett GT2560R or something similar to that turbo. i have seen in person what it can do on a 1.5l Honda engine and i believe i'll get the results i want.(sorry about the t3/t4 comment earlier...)

i belive all that he was saying was that the psi wasnt the thing that was going to hurt it...

I do mean to a point. You cant go out and run 30psi and expect it to not explode. BUT within reason, 1bar(14.7psi) or a lil over is fine with that size turbo.

You will want to check the compressor map and make sure it isnt going to choke up that high. Smaller turbo tend to like the 15-18psi range though so 15 shouldnt be an issue with a good tune. I prolly wouldnt run it hard on that setting everyday, but when tracking it, it will be no prob.
