Hey im new here and im seriously considdering getting a 94+ 240 (instead of an integra or prelude or a number of other fwd cars). If i got one id for sure do a swap to a SR20DET, but im wondering what the difference is between red and black tops.

<edit> sry if this has nothing to do with s14 engines then disregard </edit>

Ok I have a red top and a black top. The engines are almost Identical internally except for a few things. The black top has VVT and the compression is higher than the res top 10.0 VS 9.5. Externally the Blacktop has a different turbine than the redtop stock. I will have to look into it a little more but those are the main differences that set them apart besides the color. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt=':D'> hope that helps

Sigh, aren't you guys forgetting something? &nbsp;There is an S13 Blacktop SR20DET. &nbsp;Performance-wise, it's the exact same engine, the only difference is the fact that the valve covers are two different colors, and the blacktop is slightly newer than the redtop. &nbsp;Otherwise, yes, you are right on most other aspects. &nbsp;I'm pretty sure that you have the compression completely wrong though, I'm pretty sure that for all SR's it's the same 8.5:1. &nbsp;
Now, the difference between the S13 and the S14 is mainly the fact that the S13 has a T25 turbo, and the S14 has a larger T28. &nbsp;The S14 also has VVT but in the S14, it's not very advanced.

In an Option 2 book it gives some specs on all turbo cars. &nbsp;it s15 have 480cc inj, while the s13 and s14 have 370 cc inj.
they are all 8.5:1 comp. ratio.
s13 and s14 stock boost is .6 bar, s15 is .8 bar.
s13 205ps/6000rpm and 28kg-m/4000rpm
s14 220ps/6000rpm and 28kg-m/4800rpm
s15 250ps/6400rpm and 28kg-m/4800rpm
stock head gasket can handle about 1 bar of boost.
s13 at 1 bar=220ps
s14 at 1 bar=260ps
s15 at 1 bar=300ps-330ps
so far thats all i can translate &nbsp;<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sleeping.gif" border="0" valign="absmiddle" alt=':zzzz:'>
