I'm just trying to figure out my options. This is another engine I have laying here, 98 Camaro SS LS1. The computer is here but the harness is not complete. It would have a long way to go to het running. Here is a thought. Since I have this 93 4L60E setting here with low miles and shift kit, the complete TBI harness, 350 TBI, and 94 TBI computer, why not try and use it? I am wondering about using the Edelbrock Performer RPM LS1 carb conversion with ignition module, using a carb to TBI adapter, and using the TBI on it instead of a carb. I wonder how to adapt the ignition to the TBI though, or if could even be done? It's all just a thought. The trans will bolt up except for loosing one top bolt, and using the GM flywheel adapter for the early trans. It's all just a thought. It would be different right???

 

deffinately different. But I think if your goign to be buying a LS1 manifold for carb then running a tbi adapter. Why not just repair or replace the LS1 harness and do the LS1 setup. You'd be happier in the long run. I think. Because if you do the TBI you gotta do well can the injectors feed the engine..etc etc...

 

Not real sure about the injectors. I don't know!!! I'm pulling my hair out trying to figure out a decent engine combo. This is just stuff I have laying around! Hard to sell for any amount of money these days, nobody is buying up anything.

 

You have to have fuel injection? why not run the Ls1 with a carburetor?

 

Ok, let's say I go with my LS1, carbed, and the 93 4L60e. Will the TBI ECM still control the trans?

 

NO. You can't control the trans.

Interesting thought though. I'm going to throw this around in my head a bit and see if I come up with anything useful.

It can be done, depending on what you're willing to buy.

 

I know I can buy a stand alone trans control, but that's an added expense

 

Talking about using a 94 ECM on a 93 4L60e with a carbed engine, not the 98 ECM

 

Yup that's what I would do. But added expenses suck.

 

Yep. And they aren't cheap. Buying the harness may be cheaper....

 

Where to start. To be blunt, yet with all do respect, this is a horrible idea. Even if you could get it to work you will make less power than if you used a stock LS1 induction and ECM. The TBI ECM on an LS1 is like a Playstation 3 on a black and white 70's TV. Used LS1/Gen III parts are so cheap that you can get a used LS1 intake with fuel rails and injectors for less money than the TBI injectors that would be needed to feed this. If you are going to use the LS1, do it right the first time. Trying your idea is only good if you want to make less power, spend twice as much money and take ten times as long to make it it work. But hey, at least you will be "unique" and be able to say you have a 150hp LS1 that chugs at idle and gets 6 mpg. Creativity is what hot rodding is all about, however, sometimes certain ideas are just better off left untouched.

EDIT: Forgot to mention that your 93 transmission will not work with the LS1. You would be better off to sell the parts you have and put it towards a more practical combo. (IE. A LT1 swap would be a good choice for the parts you have).
