engine combo

looking to build a 200hp autocross engine, I have done the searches but not many direct answers.

I am staying away from turbo and efi want to keep it simple. My thoughts were BP and 48 IDA. Good idea or bad idea?

I wouldn't think that you need to go as far as a BP - a good street port maybe. I know that the club racing folks are getting up to 175 rwhp out of an S5 NA motor with stock ports and internals.

Good luck,

A good street port and 48IDA should net you 200 rwhp. This is assuming 3" exhaust and good ignition, properly jetted carb etc.

Unless it is stretched to the limit, a streetport and IDA isn't usually going to make 200 hp. Top National EP cars are making that, and even a bit more, but most big streeetports are making more like 170, maybe 180 without some serious dyno work and optimization.

I can live with 170-180 my car is going to weigh between 1600 and 1650....

I am using a SP'ed turbo II with na rotars and a Holley 650 2barrel
