How about if you cant answer the guy dont post, he did not ask what to swap in or anything about boost or spray. Ok man first off you need to get a Y8 head and do a mini me, use the Y8 head, 99/00 Y8 automatic intake manifold, and a 96-98 ex manual ecu. Before putting the head on I suggest you have it shaved and a valve job done on it along with any porting and polishing you want done. I would use the www.akmee.com type r sohc valve terrain kit, it is not list for sale yet but you can email them and they will sale it to ya. You may want to upgrade your transmission to a 92-00 ex unit as it has shorter gears anyway. Go ahead and use a stg 1 replacement clutch or maybe a stg 2 excedy. Run a light weight flywheel but not to light, a stock flywheel shaved to around 13lbs would be ideal. Run a good header like a bisimoto or hpracing 4-1 design. If you are willing to do the work you could fab up some ITB's also out of cbr 600f3 throttle bodies. With out the throttle bodies and with a good intake and exhaust setup you could see mid 140's on the whp and run deep into the 14's in the 1/4 mile with that if you shave a little weight.

So what is the most naturally aspirated horsepower i could make within reason, and without spending more than a swap would cost?
