Could a '95 motor go into a '92?

[5speedz34]

I plan to do a performance rebuild soon and I wanted to know if one could get a '95 motor to work on a '92 Z34. I've seen a gp with a 95 motor hooked up to a '93 harness. The reason I ask is I have a connection to a '95 motor for cheap.

Yes, it will work. The only change you'd have to make, I think, is to use the 92 intake plenum because of the MAP (92) vs. the MAF (95).

Would, it work with my harness? I'd like to use OBD 1.

Yes, it will work with your harness. The only difference (that matters, I think) between 92 and 95 is the way the air flow is measured (MAP vs. MAF).

The plenums are the same. No worries. The 91-93 has a vacumn block with a map sensor in the hole at the end, whereas the 95 has just the plastic vacumn distribution block and no mount for the map sensor in the plastic block. So the difference is in the piece of plastic that bolts to the plenum, not the plenum itself. Same plenums. Just use the wiring from your 92 and you should be set. Although... didnt the crank sensors change somewhere along the line from 12x to 24x reference?? might be totally wrong on that one tho.

The old style crank sensor is always there, at least on all the DIS equipped V6/60s up until the 3500 (they may have changed something there?!?)... the older style crank sensor is used to drive the DIS system at least... the ECM also uses it for the FI on MFI cars, but on SFI cars it uses a second crank position sensor (usually behind the crank pulley) and a cam position sensor..

i have a 1995 motor in my 1992 , i Didnt change anything only diffrence is now i have heads with a cam sensor..but since 92 computer doesnt have a cam sensor..wouldent even think twice bout it. Crank sensor are diffrent...but the plug is the same..so no worries there...my 92 motor felt faster though =( . Also the plate that bolts onto the front the engine is diffrent reuse all ur old accessieries cuz 95 alt is diffrent.

i thought only 96-97 had 24x? my 95 engine doesnt..

Did u use ur '92 harness?

Just as Cliff said

91-93 have the 3X cranks sensor ONLY. it is located in the back of the block just above the oil pan.

94+ (includes 96-97) also have this same exact sensor (same location). But they also have an additional 24X behind the crankshaft damper.


the ONLY difference you would have with a 95 motor in a 92 car is you will not plug in the 24X sensor by the crank pulley and you will not plug in the cam sensor in the front cam carrier. If you swap vac distribution blocks on the plenum as john said, you wont have to do anything else.

Thanx for the clarification Michael, its nice to talk to you again.
