Right now I just have a Skunk2 cat back, DC 4-2-1 header, and an AEM V2. I'm looking to stay NA with the car and was wondering how difficult it would be to break 200 whp.

My next performance mods will probably be new cams, maybe valves/springs/retainers, cam gears, VAFC, and intake manifold, and have that all dyno tuned at a shop.

Keeping in mind my current mods would this bump me over 200 whp or somewhere close?

P.S. I understand at that point some of the fuel system may also need upgrading to compensate for all the extra air flow.

 

up the compression, aggressive cams along with the valve train, bigger exhaust and header

 

port and polish
valve job
wild cams
high compression pistons
tuned VAFC and tuned came gears
ignition system
advance timing
intake, exhaust and maniflds
port match TB

 

Just to give you an idea... My brothers car which had an i/h/e skunk2 intake manifold, skunk2 stage1 cams, skunk2 cam gears, apexi vafc, aem fuel rail, and some other little things with dyno tuning got 185hp at the wheels....

Timing advanced slightly and it was dyno tuned. That is everything that was done to my car and I made 185.3 whp and 129lbs of torque. Oh and I had no power steering because, that added 3 hp and 4lbs of torque. The guy who tuned my car said to get the Fidanza 7lb flywheel so I did and he said I should be sitting right about 190 whp. So it will take a lot to get you to 200+whp. I know it was my goal. Untill I totaled the thing a week ago....

If you wanna make 200+ whp easy just go with a nice shot of nitrous. So much cheaper and gets it there so much quicker.

 

i will second the nitrous. Its awsome!

 

I live in cali so this thing has to be CARB legal or so that I can easily swap some stuff back in to get it smogged.

200 was just a nice round number. I don't want to do anything that will make it difficult to drive daily, and I'm not looking to put too much money into it.

Once I pay this car off and get a real job I want to sell this and use that for a downpayment on an S2000 Then I would be willing to spend a good chunk of change and possibly go forced induction with that baby

^^ look at some of the dyno charts there and see what some people are running to get around 200 whp.

 

could this really be all this guy has? are the type 3 (I'm assuming that's like stage III) cams really giving him that much of a boost?

Another question: How much would a head port/polish cost? Would it be necessary to port/polish the aftermarket intake/exhaust manifolds as well, or are they already cast with optimum air flow characteristics? (I'm assuming that's the point of buying aftermarket manifolds anyway)

 

jun type 3 cams are really aggressive. with proper tuning, it wouldnt surprise me to see numbers like that. a good p&p job by one of the top companies can run 900+. aftermarket im/em might be able to benefit from a little smoothing/enlarging of the ports. one of the drawbacks of mass production.
