I've been searching for the past hour at posts and find some of what I'm looking for........I've got a 1999 SI and looking for more power of course. I'd like close to 200whp but 180ish is nice too but hav'n a little trouble deciding what to reach that.

Thoughts:

LS or B20 block
Head off my B16A2
ITR Cams
4-1 header
2.25" free flowing exhaust (maybe with testpipe depending on tone, no bumble bee for me)
Pistons I'm kinda stuck on, either use the B16A2's I've got or switch to ITR
Hondata for tuning maybe but prob just a VAFCII
Clutch + Light fly if it matters

I'm prob missing a couple things I was thinking of but my time is be'n cut off (at the library).

Thanks!

you can't use b16 pistons or itr pistons in a b20 block. b20 block is 84mm bore and b16 and all other b series motors are 81 mm bore. if you want to go all motor and oem pistons you can get b20z (phk) pistons. the cr is only 9.6:1 but omniman built one and milled the head and some other stuff to increase the cr and got 10.7:1 cr. also i wouldn't get a vafc because hondata is around the same price and so much better and plus when most people try to tune on a vafc by themselves they normally mess it up and lose power.
