So i keep getting mixed answer with wat stage and brand cams i should get for supercharged k20a3, need help guys!!! Are other internal mods going to make a diff on the stage? Limit prolly bout 800 for the set, already got the new valves, springs,and retainers.

 

the a3 head will severely limit your cam choices. you need to either do an a2/z1/z3 head or vtec killer conversion.

 

The a2 head costly with install, if u got a semi price range that would be awsome.

 

you can always just switch rocker assembly and get cams for an a2/z1/z3

 

I'm not a huge fan of cams with a roots supercharger. Are you just looking for more power? Upgrade your crank pulley or supercharger pulley... buy an aftercooler or run meth

 

Its the jackson racing supercharger race series already the smallest pulley but its only running 8 psi wen king motorsports tuned it ive read that its possible to get 11 outta it but cant find anyone thats done it, and yes want more power.

 

Good info def going to look into that one. Thanks bro

 

I was running 12psi with 323whp on a JRSC


I KNOW it's possible.


Are you in WI because I live an hour from Kings

 

a friend of mine saw 272whp on an A3 that was stock internals with a meth kit. i can't remember what his pulley combo was but 8psi sounds like just the street kit with the 4.0" pulley

 

i would like some photos of your ride if you dont mine as i am very interested to see what you have done

 

12 psi huh thats a great deal in power have to check it out, yah im in wisconsin in fond du lac, wat other mods u got to make 300s right now im only sitting at 227whp.

 

I went from 9.5 PSI to 11.5 PSI by just switching to the larger accord crank pulley ( Honda part # is 13810-R40-A01, and the pulley is 6.37" diameter ).

my setup is k20a3 w/JRSC, 3.8" SC Pulley, accord crank pulley, modified auto tensioner, 440 RC injectors, skunk2 stage 1 N/A cams. been told I need to go with bigger injectors and/or a meth kit.

 

See you only have an A3.... That is your BIGGEST set back. No offence but it's a worthless engine. A supercharger isn't going to make any good power on that engine. Hell even a good turbo kit is limited because of the engine.


I was running a 07 K24A2 swap, JRSC with 3" BP, Accord CP, 750cc Injectors, NorBilt Aftercooler and HR 70mm TB tuned on Kpro of course.
