um i dont think there is but i am not 100%, i would check nico forums or sr20det.net i think. i am sure the s15 is different than the others since it has 6 speed and u cant swap the 6 speed onto the others.

where'd u read that...not tryin to be an a$$ but im pretty sure ive heard otherwise (about the 6spd)...educate me

I think they are all the same besides the heads not sure

ok thats what ive heard.that only the heads are different so i guess ill go with that

hmm i tried to find it but i couldnt but i kno that u need the speed sensor which is on the s15 diff and thus u would need a new driveshaft and the 6 spd is weaker than the 5 spd when it comes to higher hp.

all sr blocks are the same (pertaining to the tranny bolting up). internal there was some main girtle changes in the s15. but other than that they are basically the same. ans yes the heads/pistons/cams are diff btwn certain ones.

swaps. s15 sr w/ 6 sp into a s13 or s14 you will need the automatic driveshaft for that chassis.

some have "reported" that the use of the s15 driveshaft will make it work for any chassis, however, i am not 100% sure of this since i have never got the s15 driveshaft with a clip
