Questions of S13 Engine variants?

Hi everyone,

I have been seeing SR20DET black/red top engines for sale. I know they are turbo charged. I am interested in doing a swap in my 89 240 (290+km).

>> What is the difference between the black and the red top?
>> What is the bhp/torque rating on these?
>> Is it worth the investment?
>> How about maintanace on these engines? Availability of parts?

I would appreicate it if someone can post some info on the above.

thanx

Found info on swap in existing threads…I should have looked better.

For any one looking for similar info…

Look for the thread "SR20DET Engine Swap " & this site mentioned on this thread also gives info on engine specs : www.srswap.com/

Thanks
Bill
