Well I finally got another one of my projects finished and dynoed. This is a stock 02 Civic SI K20a3 block and head with type-s camshafts, my race header, and a k-pro. This dyno was done with just the header. There is no exhaust hooked up. That is why the hp#'s are a little high to begin with. The blue line is the stock motor, stock cams, k-pro, and race header. The red line is the stock motor, type-s cams, k-pro, and race header.


I'm sure you think that type-s cams won't work in a k20a3 head but I assure you there is a way to make them work and retain a good idle.

 

nice numbers how?? k20a3 with type s cams??? mmmmmm

 

Speak up man....

BTW nice work.

 

are those 96 (or so) GSR rims I see?

Can you please explain further? I was unaware that this was possible. lol.

Either way, nice setup and nice #'s.

 

You run the type-s rockers with the type-s cams. It is an alternative to swapping the entire head over. If you purchased brand new OEM parts it would cost you about $1800.

You just run the a2 rockers? I thought the VTEC mechanism is completely different Between the two.

 

i want to know more.

 

You have to lock part of the rockers to bypass the lack of lost motion assemblies.

Please tell how you do so!!

 

wow, im relaying this post to ep hatch amazing

 

very good to hear...more info on how it was done please

 

so y not just buy the type s head? the ONLY thing you changed was the Cams and Rocker Arms?

 

what year and car are the type s ones from? rsx correct, but what years.

 

very, very interesting.

But how's the low end? I wonder how k20a cams would do?

 

Im I the only one who sees this being amazing you can convert an a3 to an a2 w/ just the swap of a few parts. WOW, that is truly awesome.

HOW THE HELL was this accomplished. Someone steal that dude top-end so we can take a few pix jk

Rich

I'm pretty blown away about this myself. :must find cheap used type-s cams and rocker assembly:

But this brings up another question, does this mean that any aftermarket cam option available for the k20a2 will work on the a3?

k20a2 was available in all year rsx.
