is it possible to get 250whp out of a stock block jdm k20a...engine is on ep3 already has buddy club header going to switch to 3 inch exhaust....looking for induction mods to gain power...itbs (kinslers maybe) and cams buddy clubs,skunk2 or ips k2...head will not be removed...want the most useable power on stock 11.5 compression block(will limit cam choices)...any inputs??? new to kseries

 

Better header (you should contact Stefan for a custom header), 3" exhaust which you are already doing, 3" intake, and drag cartel stg 2.

 

probably gonna go with itbs...but whos stefan?from where? for the header

Definately can, theres someone here local doing it with a completely stock longblock k20z1 with ips cams. In an RSX aswell. During the tuning session.

ok will do...

 

i just hope kinsler will fit under the ep3 hood...the stock rbc touches and rad support had to be trim..

 

I think 250whp will be difficult to reach on stock block(realistic dyno anyway) unless you have the aid of some spray;-)

 

car is an ep3 with a 5.0 final drive and it moves...it beats stock evos...just looking for a lil more...250whp is just a goal...but not set on it...

 

Very doable. You'll need a set of good cams, upgraded valvetrain and other supporting bolt-ons to help the engine breathe. Good Luck

 

You think wrong.

 

Show me dyno sheets to prove otherwise on a realistic dyno. I have tuned lots of these on a Dyno Dynamics and reaching 250whp on stock engine is not a easy task even with cams.

 

Does anyone have a dyno sheet w/ 250whp/1xxWtq. From a stock block K20?
We have a customer now that's trying to hit that goal.
It's a '06 RSX Type-S w/ k&n CAI, stock IM/TB, stock cams, Skunk2 header, & Borla Exhaust. Still has. A/C ,& P/S. So far it's dynoed 208whp/160wtq. Next up is a Skunk2 IM/TB, then some Kelford 179-b Cams.
Hopefully That will do it.

The vid i posted is of a stock head cast and stock bottom end k20z1... Basicly IPS k2's with ported RBC, kidd racing header 3 inch exhaust and idk about the intake setup. This is all through word of mouth though.

 

What about rcrew headers?
