Got a a3 supercharged 440cc, kpro tuned by king and the obvious lightweight fly, exhaust system, fuel rail, and intake. Now i got 7000 and want 400 whp thinking heavy on the k20a and swapping the jrsc over.now is there a better motor out there or should i franky my a3. Plz help. Plz list possible ideas. Im sick of 230 whp.

 

It's going to be very hard to get 400whp from a roots type blower without going to an aftercooled twin screw.

Having it on an a3 isn't helping matters either.

 

My point in getting the k20a if i have to veer from the charger to turbo will also do so. Wat i can do for 7 stacks will do so. If the k20a cant put me at 400 right away thats fine as long as it has the sure potential to do so.

 

400 from a turbo is easy.

 

First buy a k24a1 or k24a2.

Second turbocharge it.

Third tune it.

Fourth bet it up.
