Im new here, so i dont know if has been posted anywhere, but what is the best header, i.e. most horsepower making headers for the k20eg swap? and where can I find um?
nikos said:Ok, I am sorry to say this but 248 would be hard IMO....BoostingB20/vtec said:what about the prototype header? any pics and how much hps it makes? my friend got 248 with that and the k-pro anyone else had similar results?
Please tell your friend to come here and post about it...
On a dynapack dyno and with excellent tuning + custom k pro maps , who knows.... but in my opinion 250whp just with header + k pro is not possible on a dynojet and a stock motor...
Hondata race car k20a eg, made 250whp and they also used a prototype header but that was on a dynapck dyno and hondata tuned their own program...
This is Hondata's race car. It belongs to Derek Stevens, one of the owners of Hondata.
Hondata claims it made 254.2 hp / 169.5 ft-lbs from a stock K20A (dynapack). Total modifications were:
* Prototype Racing header.
* Prototype Racing intake.
* Prototype Racing oil pan baffle.
* Hondata Heatshield.
* Hondata programmable ECU.
This was with a full exhaust on a EG Civic race car. Being significantly lighter than the RSX the car goes like crazy.
