here are the 3 things i would do not in any order K
you can do the TODA stroker kit go to
ModAcar
or Jun makes a good Stroker kit
both companys also make just flat out good parts to so you could just upgrade every thing far as intrnals with out stroking it out
now my fave choice.... and being that you have a B16a allready
i would get a B20 (crv) block and have it iorn sleved and all that good stuf and slap on the B16a head.
you could run from Type Rs all day wiht that setup hehehe
every one i know with one is pushing like 225 250 hp at the ground easy no tuning realy eather ... Now you tune it and add some other little things and easy you can have a 300hp all motor killing machine
wana get even crazyer turbo a CrVtec and you got 400+hp from what i have seen and heard
them would be my choices ............
