Don't get me started with that guy in the 242ps one. I posted in his thread too. The highest known hp to the wheel is something like 268whp from a 2.2 90mm bore VE with custom cams and exhaust manifold. 200Whp is getting a little more common now.

Although the 2.2L SR is getting close to 2.4L KA size, the smaller -5mm stroke full counterweighted crank along with a -28.7274mm rod length of the SR still loves to rev... what valvetrain did they choose?

Factory mechanical lifters with after market valve springs and prob retainers. Reving to 9k with big cams u don't need retainers just good valve springs, hell some of the NZ ve guys did it on stock springs.

I duno why I put lifters, lol There is a shaft that runs on both sides of the head that holds the rockers arms in place. they also feed oil to switch over to the bigger lobe. check out the head parts in this link.

Yeah, sorry about that, I didn't check that out too thoroughly.

Thanks for posting that though it helps people realize that 2.2VE's really do make lots of power. Way more than you're ever getting from a naturally aspirated KA.

So I hear, but why? Temperature?

I think any map based stand alone will do (i.e aem ems).. it doesn't have to be anything intense..

lol yeah um understandable? haha anyways, after viewing the thread you linked to, I notice the assembled or re-installed valve spring, retainer and keepers on both assembly were not really installed right.

below stated by op:

(quote) It will push it down and set them perfect. If you don't succeed, you can always take out the dark piece, whack it to remove the keeper, and start over. When installed correctly it will look like this. (/quote)

--

Please do not be confused. The valve spring, retainer and keepers have only been installed properly on the 1st or left assembly. The 2nd or right assembly is either waiting for installation or the keepers are not seated in the correct groove on the valve stem.

so on a itb sr20det would a map based stand alone or a maf based stand alone work better?? im curious to know, being that i will be using itb's and turbo.

codyace · 12-02-2009, 06:04 PM

I know this may be against the norm, but search for posts by 'greaser' over on FA...hes had some detailed KA (n/a) builds, and there is certainly some information to be learned from his results.

project-D180 · 12-03-2009, 12:50 AM

greaser is tha f'in man wit the n/a ka's he the only one i seen so far that actually built a 200+ ka motor while every one else is thinkin a couple of bolt on's and they should magicly have 200 hp with no high comp build n a tune
