over bore

[macdaddy]

what is the max I can bore a sr20?

[Dattebayo]

Not much with reliability. Get a stroker kit to make it 2.2 liters. You will have more results this way and less hassle.

None if you wan't to preserve the nikasil cylinder lining (GOOD idea) otherwise, have it re-coated after being bored. Having it re-coated can be difficult sometimes, you have to find a place that can do it, look for snowmobile motor shops etc. as they tend to deal with it more than automotive places.

or re-sleave it

[s13sr20chris]

mmmmm, sleeves! you can sleeve it for big block powah baby, but over 15% you will need new head castings. you have been warned. tomei stroker looks good eh?http://www.tomei-p.co.jp/tomei....html

[Nathan]

Yeah, or re-sleave it...Darton could probably make some nice ones for ya

[s13sr20chris]

you still can only go so far without a solution for the head problem.

[solaris22]

sleaves arn't expensive at all...fyi. Anywho, the 2.2 kit will more then likely be more then most people will ever need. there are the few trying to reach 700-900hp that do resleave. otherwise it's pointless.

[Dattebayo]

Yeah unless you wanna give JUN a run for it's money, just stroke it baby. You'll get plenty of power that way.

Just did the calculations and WOW. That stroker kit mentioned above is $2735. OMG there got to be a slightly cheaper one...

nah i don't think you find much cheaper, heres the 2.2 stroker kit from toda http://www.todaracing.com/products/niss ... e_kit.html it'll run you $6,400

You wont find any good stroker kit below 2200. Unless someone just hooks you up. It would be sweet to get my hands on the Tomei kit though. I'm still wondering if I want to invest in a stroker kit. Would be nice though.

[s13sr20chris]

sleaves will require expensive machine work. thats is if done right.

[macdaddy]

Im not boreing too get any more cc's I have some damage caused by a piston that had a quarter size hole in the ring groves. I bought the engine from ebay big mistake! It turns out that just because a engine has low miles that it does not meen its a good moter. the turbo shaft is bent also the guy in japan must have ran the hell out of this thing!!

[s13sr20chris]

[macdaddy]

[s13sr20chris]

just honing? .040 enough? i did not see it so i will have to take your word for it then.
