I am just completeting an engine swap on my 1993 4runner. I got it cheap with body damage and a bad hg. I bought a running 3vz out of a guys 88 runner that ran good 140k 5k on hg.( I saw/drove it in his truck).I ran into several problems installing first of which was I need different motor mounts the older block had no upper mounting towers only flat flush mounting holes.so I got the mounts from.the guy I got motor from and gave him mine. He is doing. 3.4 swap so I think he needed them as bad as I needed his. Next I noticed thermistat had a hose comming out of it and the older didn't. And injecter plugs were a little different they were broken on harness already so I rammed them in so they were connected.distributed was different connecter so I swapped that.knock censor was difernt so i modded that.Truck turns over wont start or sputter but smells like fuel and I checked spark its there I tried tdc with it at 0 . Any ideas?

Some others will chime in here soon. But I'm pretty sure the 88-and 89's had different fuel injectors. Like you said the plugs were different.
Not sure if that would matter, especially since their probably wired the same.

Could have somthin to do with the distributer. Sounds like its not sparking.

What exactly did you do with the dist. plug again?

And what do you mean by "I tried tdc with it at 0"?

Jbowls

I meen I rotated the motor til the mark was at 0 an set new rotor pointing toward the number one spot.

I pulled the number one plug and had my girl friend turn it over to check spark it was there. Thanks for replys by the way

Make this easy on yourself and run the 88 engine with your 93 upper intake and wiring harness...Use the 93 distributor. the pipe on the water pump goes to an oil cooler that was on your 93.. You can swap that over.
The 93 injectors are different than the 88 injectors... You will need the 93 injectors to work with your old wiring harness and the ECU.

X2 this is good advise.

MudHippy

I say all you need is the 93 fuel injectors. The 88 are lower resistance, so probably aren't going to work. But the 88 distributor will work with your 93 ECU, if you've modded the plug/wiring correctly. Other than that you really don't need an oil cooler. And since you didn't mention anything else being different, why you'd want the 93 upper intake too is beyond me.

BTW, have you checked for codes? Sometimes they'll tell you where to look, even if the engine won't start.

You could use the 93 distributor with the 88 head(s). But it might require modification.

Hi! I'm doing the same thing but in mirror....a 93 into an 88... the crank mark on 0 ..pull the distributor.....note on the block where it goes is a raised mark....this lines up with the mark on the distributor....now looked at the drive gear...there's a mark on the top of the gear..a dimple....this lines up with a mark on the shaft ....line up the dot to the shaft mark....then drop in the distributor into the hole and the marks on the base and the mark
on the distributor hole ...viola...dead on the monkey.....

Only reason I say upper intake is because everything is on it and it is easier to swap the whole thing over than to have to swap all the parts. The sensors on the sensor bank on the rear of the intake are different and would have to be swapped. And there could be a difference in the T/B.

1. It doesn't need an 89 distributor.
2. Depending on the head(s), 89 vs. 94, it might not even fit without modification.
3. No, it wouldn't run better.
4. Yes, it's compatible AFAIK. But the 94 has a slightly different cap and rotor, a larger diameter shaft, a different plug/connector for the wiring harness, and the positions of the Ne and G signal rotors are inverted. I've never compared my 88 side-by-side with the later version. I've just seen lots of pics of it. And there's already been a thread about the wiring connector difference(https://www.yotatech.com/forums/f116...p-asap-225109/). The rest I've inferred from the information found here: http://autoshop101.com/forms/h23.pdf

Is there a chance it is severely out of time I was trying to start it and it fired nut out my manifold. I know there way different but when my sbc Chevy but when it is out of time 180° it will fire out the carb maybe something similar happening here?

ThatGuy1295

No.. Wouldn't think so. Backfiring or anything like that can't really hurt these things.

I've got the 93 igniter and the GM module to work on my 88..... made a jumper harness to go from round 88 to flat 93.....used an accell coil....manifolds differ from the way the throttle cable/ kick down cable mounts....other then that....all was the same......throttle position was same style...... its how the bracket bolts to the manifold that make a difference ....
