Just recently purchased a 1993 Z28 engine and transmission. I will put this engine in a 1989 RS that currently has a 2.8. I know, I should have just brought an 89 with a LT1 already in it. I have enjoyed my RS so much that I want my son to have it. He is 11 now, and in a few years he will be able to get his license. This car will be a daily driver until he is of age. I am not a racer or anything like that., I just want to enjoy my car a bit more. Anyway, please give me a little help. I have the engine, transmission, MAF, all brackets and braces, PS., and etc from the 93. I don't have a fan yet and don't know what else I should be looking to buy….. If you folks could throw a dog and bone and give a hand I would be forever thankful.

mat89RS...I am watching your posts with a lot of interest!


Thanks

Ron

 

Hey Multi-taking well I've read so far a least 10 websites with explaination on engine installaion.
the best ares:

The hardest thing will be to removing the gas tank and put a high pressure fuel pump. Then there's the thing with sledge-hamming your cross member to fit the A/C compressor, It's pretty easy to do so don't worry about that. Also I hope you have the original key of the 93 car because there's a resistance in the key for a system called v.a.t.s. (vehicule anti teift system) if you don't have it you will not be able to start the engine. You'll have the find the ECM right resistor and solder it to the 2 small yellow cables comming out of the ECM and going the the key barril don't for get to remove the resistance on your key because it will change the value of the total resistance.The 2 cables ares located right under the sterring colum panel )...they can have other colours. There's a possibility of 15 different resistances mine was 519 ohms.You'll also have to make a fuel fitting for the fuel line because you can't connect the old fuel line directly on the engine fuel intake. I recommenced getting plastic fuel line it's easier to work with. Another thing !, the air intake will be lower than a regular TPI engine so think about fabricating an air intake. I'll be using an intake from a 2.8 camaro MFI 1987 it fits perfectly. You're lucky by the way because you got the 3.42 gears in your rear-end , myself i got the sh*ty 2.73 for now. sincwe you have a v6, you'll have the change the suspension on your RS because if you keep it stock you rear wheel will be spinning like hell because the weight is not well balance and you camaro nose will eat pavement everyday !!!Don't know if you know but the manifolds of the 4th gen engine will not fit , same thing with the y-pipe , I would recommence get a v8 y-pipe and manifolds but if you wanna go with header buy the hedmans headers you'll have little mods to do but it soulhd bolt right up !!! anyway hoping that this will help alot !!!

Thank you Mat89RS. I have visited this sites that you mentioned and you are right., there is a lot of information. I should receive my engine sometime next week. With luck, I hope to have it in the car in a month or so. I can see I have a lot of work to do. I am hoping to buy as opposed to modify as much stuff as possible. Again, thanks...

 

Well great, keep on swapping baby !!!
I just got my LT1 this morning !!! looks like a big fueled monster !

I trying to find some ECM wiring schematics for 93 harness ! hard to find.

I think that one problem you'll have with the 1993 wiring diagrams for the ecm is that
the 1992 and earlier 3rd gens used the prom.
In 1993 they went to the obd 1. In addition,
after 1991, they incorporated the engine harness into the main harness. You may be looking at a complete rewiring job with a new ecm as well.

 

Ouch!

 

Actually, a 93 LT1 STILL used a prom chip. 1994 was the first year of OBD-1. You're either going to have to use the stock computer to control the gauges and the LT1 computer to control the motor, OR send your exsisting harness off with the 93 harness to a company and get them rewired and made into one harness so that the harness is setup like the LT1 was supposed to be there in the first place. I used a company in San Antonio called Fuel Injection Specialities. Their website is www.fuelinjection.com They did a good job on my harness, but it took a little while because the owner had died in the time my harness was being made and they were having problems getting reorganized. They do good work, and the turnaround time is usually about 3 weeks. My harness and computer reprogramming was $725 and it came and everything plugged in and the motor fired up on the first try. Just thought I'd pass the info on since it didn't look like you hadn't gotten much help yet.

------------------
'92 RS convertible with LT1/t56, slp headers, 3" high flow cat, 3" flowmaster w/2.5" outlets/reprogrammed computer, k&n filters, "modified" eibach springs, kyb shocks&struts, polygraphite bushings, custom subframe connectors, and 4.10 gears.

 

BTW...the harnesses for those things disconnect at the firewall plug and rap around the engine bay, behind the bottom of the fender, then run under the dash where they plug into the computer. If you take it loose at the firewall and computer, you can send that harness off with the engine harness from a 93 and they can be grafted together.

 

Hi, I am doing my best to try and keep up. Hi mat89RS!

Let me ensure that I understand what has been said so far.

1. I must change the fuel pump., most likely not a bad idea to also change the fuel sending unit.
2. My AC compressor will not fit into the cross member. There is a chance that I can get a cross member from a 93 Y-body and it will work.
3. I need the original key from the 93 Z28 to ensure I can start the car. If I don't have the original key, than I need to either rewire the computer or buy a new wiring harness.
4. I will need to change the fitting(s) on the fuel line. My current fitting(s) will not work.
5. I should be able to take the Air Intake from my 2.8 and fit use it on my (new--to me) LT1.
6. I need to find manifolds and/or headers and pipes from a 1993 Y-body as my V6 stuff will not fit.
7. The 1993 LT1 is speed density as opposed to MAF. (What the hell is speed density?)
8. I also got the computer and wiring from the 93. Do I need to re-wire (baring key thing) the car or can I use this stuff.

Prior to purchasing the engine/tranny I did not do a lot of research. I have had Baby since July 1989, I got her new in Jackson, MS. She is a real head turner, but she has over 200K on her and is in dire need of a new engine and tranny. Again, anyone that can provide me additional information, I would be forever thankful. I did not a little research, but not enough. I am only a little bit confused at this point… (I Think By The End Of Summer, I Will Be Looking For A Bud To Blow My Brains Out!) Regardless of what -- I will keep my baby. I have a bad feeling I am not going to make this happen, but I will shoot my best shot.

 

Hey, don't get discouraged. There were days where I thought my car would never be back on the road ever again, but just stick with it and take your time. When you get there, you'll look back and go, "ahhh, it wasn't that bad."

 

Multi-tasking there's some things that you'll need to make some research on ...

You don't really need the actual key of the 93 but you need to know what's the value of the pellet resistence on it. then you'll have to go at radio shack and get 1 or more resistences to equal that value. Second thing, the manifolds & y-pipe will have to be from a 3rg gen V8 or you may use the 4th gen but good luck with this because the cat will sit on the frame and also the flage on the 4th gen y-pipe have 3 hole for bolting onto the manifolds, 3rd gen only 2 ... Something else I didn't talk about is the radiator, It would be better to use a rad from a 4th gen LT1, to match up with the water pump, myself I'll use the 3rd gen one but I'll have some plumming to do.Also you'll have to think About the wiring harness I'm little confused right now because I've just received my engine and harness and there's so much wiring to do. My head is rushing like crazy right now just thinking about the rewiring but I want to do it myself. Oh, about the fuel pump, I was thinking about it and you might be able to use your old one, check the psi and if you get 46-50 psi you should be fine, I think !. The 93 cross member is not the same, you'll have to hammer it down yourself.

Could someone tell me if my posts are even showing up....you guys don't seem to be responding at all to what i have said. Just curious and if you guys wanna ask me anything about the swap, i've figured out this stuff you guys are trying to figure out. I thought about trying to rewire it myself, but it just wasn't worth screwing with, and if you get the computer reprogrammed, they'll remove the vats module and do some performance tuning to the computer.

 

oh, and a 91-92 TPI 350 fuel pump will supply plenty of fuel to an LT1. I'm running one and it is doing just fine.

 

Fredo92, yes your posts are showing up. I am sorry, I was not trying to be rude. I have not checked out the wiring stuff yet. Mat89RS is starting to work on that now. I will visit the Fuel Injection site and check them out.

Thanks for the info

 

Actually fredo92, what do you mean by "computer to control the gauges"? I thought cars only had one computer!

 

Hey guy, would you know where I could find information about the wiring harness of a 93 z28 because I'm seeing information about 694-96 and 97-up but nothing about the 93 ...

multitaskin....when i said, one to control the gauges and one to control the motor, i was reffering to the LT1 computer to control the motor and the orignal computer to control the gauges. Some people have done it that way, but not I. Sounded a bit fishy to me.

 

Ok my turn for easy swap directions:

1. Painless wiring harness from jegs: $350
2. New chip without VATS $200
3. Painless wiring harness for car: $300
4. SLP 1 3/4" headers bolt right up: $350-550
5. 1LE A/C delete idler: $60
6. New fuel line from near drivers side fender to fuel rail: ??
7. New power steering lines fabbed: ???
8. Use 4th gen rad. or be cool replacement. ??
Doing it that way there are no wiring nightmares no beating up of your car and its an easy drop in swap, of course you could still do the rest and just do the beating up of your crossmember and weld the mount for the A/C and new a/c lines will also be needed, and you could easily just use the stock V8 3rd gen manifolds and y pipe.

 

Hi Z28racer. Looks like you are saying we should buy two wiring harnesses..I hope thats a typeo! You sound like you have don't this before. Hope so, mat89RS and I need help.

 

Hi mat89RS. concerning a wiring diagram, I have a Chilton's which contains wiring and vacuum diagrams. I have not found a decent wiring diagram for 3rd/4th gen on the net.

 

Basically yes that is the easiest way and the way I am doing mine, havent got either harness yet but it will eliminate the wiring nightmares as the new harnesses are both labeled and custom type as far as fit, the LT1 swap harness makes it a straight drop in for the swap and the new car harness will elim. any unneeded wiring and make it a lot more pleaseant Check out www.painlesswiring.com

 

Z28Racer., what are the part numbers for these harness? I am not beyond making my life easier.

 

From Jegs:
LT1 kit: 764-60501 price: $350.99
18 circuit car harness: 764-10201 price: $299.99

Z28racer, I am at a lost. I read the information concerning wiring harnesses on the Painless Wiring web site. Why are you replacing your computer and classic wiring harnesses? Do I need to replace both also? Is the LT1 harness somehow connected to to the classic harness?

m-t

 

Hey multi-tasking it is possible to keep the wiring harness if it's a 93 but there's lot of connections, Myself i'll keep the stock one but it's a nightmare do work with this since it not a 3rd gen wiring harness

------------------

The LT1 harness would work just fine with the stock harness but there are a lot of things on the stock one which will not be needed thats why im going with a new chassis harness.

 

Hi mat89RS and Z28racer. Sorry it taken so long to reply to your posts., I have been out of the loop. I should get my engine and tranny this week. I hope I am up to the challenge of dealing with the wiring and such. I am not sure if I will go with the wiring that will come with the engine or buy from Painless. I have been doing quite a bit of reading and I think I will go with Painless. Mat89RS, how is your wiring work going? Is it as bad as you thought it would be?

 

Well I'm waiting on e-mail from people for wiring diagram for passkey module, but so far so good I got about 3 other connections to figure out. I also solved all my tranny-rear end problems on the news-group ...

anyway time to go

So if you use the corvette LT1 or the 'vette mounts you don't have to pound down the crossmember? I read somewhere that the vette mounts make the engine sit a bit further back in the engine compartment so the ac clears the crossmember. Any thruth in this??

 

Hi FBODY-ADDICT, I am not sure....I am certain on of the other guys could better answer your question...

What type of swap are you planning?

 

Hi guys....Just wanted to let you know that my engine and tranny arrived yesterday! I will start with the wiring and document as I go.

Wish me luck!

 

Hi multi-tasking, yeah right now I'm sticking to a 3.4 swap for my 85 firebird but I wanna get things clear cause once I'm done with that my 88 formula 305 needs a power boost, and what better way than going Lt1.

I found out that if you use the vette stuff you dont need to modify the crossmember cause the engine accessories aren't as low as the ones on the Fbody and the AC compressor sits on the opposite side of the car so it has room.

 

3.4s are sweet. I enjoyed my 2.8. Great gas milage and I could act a clown on the hwy. As far as the LT1 is concerned, I have two problems. 1. Should I use the wiring harness that came with the engine? 2. The stock manifold that came with the engine looks good. I want to keep it., but a friend says it will not fit into my car's body... Is that true?

 

Impossible to keep you're manifolds because they got 3 bolt for bolting to the y-pipe. 3rd gen only have 2. let say you would install the 93 manifolds and connected the 93 y-pipe, the y-pipe would be sitting right on the frame and I guess you would like the vibrations in the car. You can get the wiring harness, I'm doing wiring job today

got to go

------------------

One of the companies that was recommended up in the first couple of replies( dont ask which cause I don't remember ) will take the harness that came with your new(to you) LT1 and adapt it to work with what you have, I think that's the way to go.

 

Hi FBODY-ADDICT. I have not decided which harness company I will go with but yes I do have the information.

My current problems are: 1. Exhaust manifold -- Do I need to use f-body? 2. Motor mounts - What motor mounts can I use? What is a good after market motor mount?

 

Multi tasking, why don't you use the 3rd gen motor mount , they will fit perfectly if you don't have A/C and if you do well I took me 40 minute to cut them the way I wanted and I had to weld a little bit .




------------------
89 Camaro RS Stock as a women with white panties

mat89RS, this car is a daily driver and I live the the very deep south. I would die without A/C.

So, once again, what motor mounts do I need to use so I can keep my A/C?

 

I think regardless of which mounts you use, if you keep the AC you need to pound on the crossmember unless you use the 'vette accesories( which would mean more $$$) I would just go ahead and pound on the crossmember a bit.

 

Well about sledge hammering the cross-member it's not really hard it took me about 5 minutes with an roung tip hammer and a blow torch and I doesn't look bad.
