ca18et wiring loom, trying to figure out if it will work on D.

[hopeful]

If anybody knows if this wiring loom will work on a CA just tell me, if not then tell me this. Does the wiring to the ECU have one big plastic thing or is it seperated into three pieces?

[hopeful]

Could somebody please post a pic of their stock det ecu.

And is the CA18DE's wiring loom the same as the CA18DET?

Are there any good info sites on CA18DET's other than this board?

[themadscientist]

no, the E has a distributor with eight plugs, the DE has a crank angle sensor and four coil over plugs just for starters.

[hopeful]

E having 8 plugs shouldnt matter seeing how you can just disconnect it. fyi, they also came in 4 plug models.

I aint no pro so could u explain what the problem is with the DE having a crankangle sensor and coilover plugs? (whats that too)

And could you give me a site with specs and information on the CA. Id like to learn more about it, it looks like it has valve timing advance as well?

The CA18 SOHC has a distributor and a coil for each bank of plugs. It plugs into a completely different kind of computer than the DE, an antique one at that. So it has no plugs to connect to the crank angle sensor, firing box, coils, three wire O2 sensor, the plugs for the intake will be the wrong length and likely the wrong type. What you are suggesting would be the eqivalent of trying to wire up a brand new C6 vette engine with an old 82' cross-fire injection harness, it won't work.Save yourself an explosive anurism and get the proper harness. I'm sure there are several members here who could go on for days of the horror of making the CA18DE harness just hook up to the 240SX body.

The CA does not have VVT.

[hopeful]

actually the ca18et does have a crank angle distributor. it has coils, it has an O2 sensor. it only has one distributor.

Im trying to make the CA18DE or CA18ET harness work on the CA18DET. If that wasn't clear.

Why is the ca18et's ecu an antique one?

and again can I please get some information on the DET engine, I cant find properly organized information anywhere on this board.

[themadscientist]

You can use the DE on a DET, I had a DET harness on my DE so it should work in reverse. Make sure you use High impedance injectors or splice in a dropping resistor if you will use the stock low impedance 370cc ones.Every ET I have seen has a dual race distributor and two plugs a cylinder, do you have a picture of the motor you are talking about? What CA info do you need other than this wiring harness question?

[hopeful]

thank you, the ca18et's of the UK and most other non northamerican countries came with 4 plugs. the 8plug was only used as emissions stuff. I dont have a pic of it off hand, but its the same as a normal ca18et, just minus 4 plugs and a different distributor + ignition electronics. I just want to know general information on the DET just to compare it to my ca18et. Something like best upgrades path, how much psi can stock internals handle, all that type of stuff. I would hope that there is a website about em, its not that unpopular.

you could take a good condition used CA18DET and with bolt ons and very judicious tuning get a very reliable 250hp. Open up the motor, start throwing in forged pistons, cams and other quality internals and 400hp is attainable.

ic... that thing i thought was VVT, whats its real purpose?

Didn't some years of the CA18DET come with an intake manifold of 8 runners, 1 running low rpms, and both at high?

There must be a more informing site about this engine somewhere, thats the kinda things I want to know about it. Having 2 intake runners per cyl.

If you mean the circular silver sensor at the front of the head, that,s the Crank angle sensor I mentioned.

They both have that design but the S13 DE ,model is much better as is the head casting.

The CA is not "the" motor of the moment like the SR, the RB20 suffers from the same overcast shadow from the RB26. I have the FSM for the CA18, I can quote you any measurement or clearance you want.
