It's still an SR20det though, the main reason it makes more power it the ball-bearing T-28 turbo. If anything, from what I understand, the S13 sr's head flows the most air , and you can always change the turbo on the S13. Plus, I've read in a lot of place the S15 transmission is pretty weak. I mean, unless your just gonna leave the engine stock, then go for the S13, its just a better investment. you can find them for like $1,200.00 on ebay (if your feeling lucky), and they can be tuned to make the same horsepower levels as the S15 sr. If you took all the engine modifications Signal did to their S15, and got their equivalents for an S13 Sr, you'd have an almost identical setup. You should have no problem pulling off 600hp out of a built S13 SR with a T-78 (or T-88, they switch it around from what I understand).
BTW, I saw the signal S15 at a the import expo here in texas a few months back, almost spooged my pants.
