S13- S14 parts interchangability

[SX APPEAL]

searched, still need answers. Recently my beloved S13's engine self destructed, luckily I was int he process of getting an S14 at the same time. The S13 was a 91 LE, S14 is a 95 base model. So now Im wondering what parts I can swap over. I have a lightweight flywheel on the S13 that Im all but confident will fit. Wondering about exhaust system parts, the header in particular, flanges arent a problem it can be welded, but do all the egr and sensor bungs line up? I'm also assuming the intakes will interchange, besides the different MAF they look the same. Anyone that knows for sure please lmk, thanks

Oh one other thing, the vehicle speed sensor on the transmission, the one that feeds to the speedo

Something is telling me that one intake has butterfly valves and the other doesn't... unless you just mean the CAI I think that works with both although when I bought mine it was 95-98 specific. Not sure on the header because S14's have 2 O2 sensors and there's a size difference between the 2

flywheel - yesexhaust - no unless you change the exhaust hangers header - if they're both dohcs, yes. line up everything else, not sure on that one, I'm guessing probably though. intake - slightly different.

Thanks for the replys. The car already has a 3" exhaust, what I was thinking of doing is just throwing my header and a high flow cat at it to make it complete. I can just have that stuff welded in with a flex joint if necessary, just as long as the egr and first O2 sensor fittings match up. Still wondering about the VSS too, cause the speedo in the new car doesnt work and i would just love it if I could just swap my VSS in and make it work, cause I'd venture a guess its a pretty expensive part from nissan.

My buddy has s13 dc sports headers on his 1998, I remember him saying that they did have to modify them to fit. *I distinctly remember him saying he had to have the muffler shop heat the piece so they could bend it (not enough clearance) and he did the weld-on bung deal for the 2nd O2 sensor*

If he had to bend the piping i always thought that maybe S13 ka's sit lower in the bay and require more angle for maximum clearance but who knows - torch it, bend it out, and then flex pipe it - donecut the exhaust hangers and weld some new ones on - doneget rid of your EGR crap - done

good luck
