What parts can i buy to get better performance/horsepower from my F22a6

[SOHC-FTW]

8whp? What are you smoking, my friend? It made 28whp on a bone stock F22A1, untuned. There's a reason why it's so pricey... it provides more power than any other single bolt-on part (not including forced induction, of course...)

Only made about 10whp tuned on 19dabeast36's bolt on set up at TDC.The way i see it is unless your doing top an bottomend work that $800 could go else where just IMO.Bisi lvl 2 cam an a used Nitrous kit an a tune would put you at about 1-1.2k which you would benefit alot more power from.But i wouldn't do either without knowing for sure everything is in tip top shape.

If a swap is in your future, buy parts for that instead of squeezing power from your stock motor. You may be able to squeeze enough power out of your factory motor to make you happy but nothing compares to twin cams. An H series swap isn't that expensive overall. I will be spending maybe a total of $1500 and that includes $1006 for my JDM H23A shipped to my door.

Twin cams are just more parts to replace when something breaks. The ONLY advantage to twin cams is the ability to adjust the valve timing without replacing the cams and 99% of the people building aren't ever going to need to do that more than once, so there's no need for DOHC except to say you have it.

You just dropped a grand for a 200 hp engine (which will probably put down less than 175 by the time it gets to the ground) that will still need to be built up to be faster. For the same $1500 you mentioned, the OP can get a bigger cam, a Bisi header (which is only a substantial hp increase over a couple of thousand RPMS in the high end. Up to around 5K, it's not that much (<10), but above 5k, WHEW BABY!!), a generic catback with a decent muffler and the a6/h23 IM/TB combination and have a SOHC F putting down more power than the h23a and probably share a pizza and a six pack with it when he's done.

I've got less than $2000 in my entire car (including the car and the stereo system) and it's putting down about 165 whp (190ish at the crank) on the A1 manifold, with a stage one cam, Spyder Auto full exhaust and an SRI.
