I dont want to re-wire cuz I hate electrical setups...so which car/years should I stick to to maybe just plug my PCM straight in....

or which cars should I be choosing to make the swap the easiest.

My car is manual so does that limit me to only manual Fbody's?

Can I use V6 fbodies? auto or strictly manual?

Basically I don't want to re-wire.....I dont mind maybe converting an OBD2 computer to OBD1 if that can be done or maybe simply deleting MAF from it...I know the K-members will be different if I go to V6 but what else do I need to choose or think of b4 I find a transplant? in order to make things the easiest?

My car has a fuked up frame....tried with some shops to fix it but ppl are lazy and they dont want to re-reference the computer after they pull on it once...so rather than spend more money...with no fix...i'd rather find a donor.

93 is 93. 94 and 95 work together, 96-97 work together. So you, like me, are stuck with 93. You don't have a PCM, you have an ECM. ECMs use EPROMs, where PCMs use EEPROMs and also control the transmission for Automatics.

You don't convert the computers to OBD1, you convert the car to OBD1, basically using a OBD1 computer instead of the OBD2.

I don't know anything about the differences in K Members between 6 and 8cyl cars. So I can't help there.

Well if my 93 is obd1 then I should be able to take it into an OBd2 car no?

I'm guess this rules out using a V6 car entirely?

I have to stick to Z28's auto or stick shouldnt matter but beyond that I have to stay with a 93?

No, you can't use a 93 with the newer stuff. Totally different computer system, which I explained to ya.

Find another 93 car, or deal with having to re-wire. There's no way around it, sorry.

We can just put in into my 94 Z.

Why don't you just pull the whole engine wiring and drop it into another car if you don't want to splice stuff together so badly.

The '93 engine can be swapped into any LT1 car with some changes, which depend on the year vehicle that you are swapping into. On the engines themselves, '96 - '97 had a different knock sensor (knock sensor, not knock module, this is not a typo). Also, the opti's are different for '93, '94-'95, and '96-'97, as well as the timing covers (I.E. a '96-'97 has a provision for a crank position sensor which the previous years did not have, '94 - '95 is different from '93 (I believe) because they changed the style of opti used). The fuel rail on a '93 engine is also different than the rest. Obviously, the '93 is a speed density setup, and the other years are all MAF, so you'll have to retain the MAF from the donor car. I wouldn't recommend swapping into a V6 car if you're looking to avoid wiring issues. Everything else you should be able to carry over from the donor car. This shouldn't be that difficult of a swap into a V8 car. The point is, you CAN make an early model LT1 work in a later model vehicle using the later model's wiring, it just requires some updating of the motor.

If I am mistaken in any of this, anyone please correct me. I don't want to mislead License2Ill, and its been YEARS since I sold my LT1 car, and my knowledge in that department fades with every beer I drink.

Topdown has it all correct to my knowledge.

I'd like to add, 93 have 22# injectors and the rest have 24#. If you have aftermarket, that doesn't matter then.

Just swap your harness+computer too.
It will save this headache your dreading.

First of all I want to thank everyone for helping. There's some frame damage that I just can't drive the car with cuz it burns the right side of my brain just knowing about it.

I re-did the drivetrain on it not too long ago so I dont want to junk it.

I think what topdown is saying is as best a solution as im gonna get.

Basically(correct me if im wrong) stick with a Z28....retain the MAF and the knock module if I go with 94-97.

My 93 has been converted to the later Vented opti but I dont think I have the crank position on my timing cover.....it is a later timing cover tho for sure..just dont know what year. I guess if I really wanted to I should be able to get a crank position timing cover. But I would only need it if I bought a 96-96 donor i take it?

Will I need in all instances the later fuel rail??

What if the Z28 is auto? any worries there?

I have 24 pound injectors as is..and my "current" ecm was programmed for them. I know all that would be lost cuz I'd be on a new computer.

In essence i'd be in a full pledge later year'd car. Any other little engine parts I need to worry about?
So far we have:
MAF
possibly timing cover+crank sensor
later knock module
Fuel rail yes or no?

Again I won't need chit if I go with another 93.
But V6 is ruled out unless i want to re-wire which just uttering is making me wanna puke.

Will my headers carry over? Hooker super comp shorties.

Oh can't I just program out the MAF?

RedMike if I did PCM+harness I would have to take the chittty 93 guage console too wouldn't I?and dissamble not 1 but 2 interiors? -gagging-

If you wind up needing it, I might have a spare timing cover laying around for a '96-'97 w/ the crank sensor.....I'll just have to look through my pile-o-LT1 junk. I know at one point I sold some stuff on eBay and CamaroZ28.com, so I don't know what I still have and don't have. Also, I still have the LT4 I built for my '96 sitting in the garage collecting dust, so I might be willing to swap timing covers with you if it comes to that.

As far as the exhaust, if you're using shorties and the factory Y...it will be different if you go to a '96-'97 car....they used dual cats, and the earlier cars used single cats, and I don't think the later Y pipes will bolt up to those shorties...I could be wrong though.

The cluster I'm not so sure about, but it is a very real possibility.

I swapped a 93 transmission into my car(1995) and the VSS, Back-Up light,
and reverse lock out are different from the auto.

So depending on what you swap into you are going to have a unique set of
problems, so pick your poison.

I think in the long run swapping harnesses would be the best route.
Electrical gremlins from splicing and buying new pigtails for compatibility
may get old.

93 uses a 700R4 (4L60) where as 94+ use 4L60E, which would be basically a 700R4E (but they never call it that.)

I believe the fuel rails are different. My brothers fuel lines look a bit different than mine.

lol You didn't read the thread did you. We listed that a few times over.
