Got a chance to finally start tuning the other 2.2L SR I finished up a while back.. First dyno is .8 bar, 2nd dyno is .95 bar. It's a 35R .82 with only 264s2 and solids. Slightly conservative timing and 7700 rpm limit for now. Next week.. a little more timing and 1.35 bar on pump gas.

1.05 bar pull and got 411rwhp. Can't get the wg to stop creeping around

 

Well, I actually started a thread a few down about a possible stroker/bore combo but now that I see this looks like I have to start saving my pennies for you to build me a bad ass combo like this! Hope you're ready to do another one! Once I build my head this will be the next step. Can you ballpark a # for me as to how much this would cost in relation to a regular build(ie: 86.5mm CP's, rods, bearings, main bolts). I gotta know how much to steal from the bank!

 

not much more than a standard build, except the sleeving is like $1200 additional + freight. cp's are aroung$450-$500.. pauter rods are like $600-$700.. oem bearing set is around $120.. 86.5 bore out is part of the $1700 motor build fee. Big Bore owns all.

 

damn good numbers cant wait to see this car...

 

nice....good job martin

 

Sweet! A stroked SR. Nice numbers man. I am not wanting to start a SR better than KA war type of deal, but if your going to stroke the SR to 2.2 and completely redo the entire engine inside, why not start with a 2.4? Just curious as to the benefits of either.

DO NOT ANYONE START A SR>KA or KA>SR post.

 

I'll correct for Martin: Not stroked, bored. I believe this is using the stock 2.0 crank but the cylinders have been bored out to accept 89.5mm pistons resulting in 2.24L's of displacement and probably no loss of rpm. I started a thread a few days ago dealing with a custom stroker kit and was wondering why not combine both. Take the 2.35L stroker kit, sleeve the block and add 89.5mm pistons to create a 2.59L SR26DET monster. Who knows, maybe I'll get lucky and win the lotto then just do that for fun!

 

haha +1 on SR26DET. I always thought 2.2 was achieved through a longer stroke? Cool beans either way.

 

Yeah as far as I know the big company kits out there (HKS and such) are created using a longer stroke than stock but retain the factory bore, or at least close to it.

 

ya.. leave the long stroke to the ka.. it can have its torque.. rpm = hp simple as that. that is why that this 2.2 @ 8000rpm @ 11psi makes 371hp... 422 @ 15 psi... this motor WILL break 520 hp on pump gas @ 20 psi.
