LS1 into LT1 Fbody Help Hey guys,
I've search and can't find a difinitive answer, nor thread. I have an LT1 car, that I'm swapping a LS1 in, I have the Motor, Trans, harness, accy's and PCM, K Member. What else do I need to make this conversion work? Will I need a whole different cluster? I have the 97 Digi Cluster. Any help will be appreciated thanks!!

The cluster is different. I know that for a fact, because I performed a dash swap from the 93-96 style camaro to the 97+ style. Only the 97 cluster will work for the LT1s. The tach, speedo, fuel level, and a couple other sensor will not work at all.

Yes, that's correct. You send us a factory LS1 harness and we'll modify it for a full plug and play back into the LT1 car. It's $500 for the mods and includes the correct diagnostic port when needed, etc.
Plug everything in and go!

John is the man at Speartech. I converted a few years back from LT1 to LS1. Sent him my harness, got it back and it was plug and play. Very excellent work. And no guessing. Also I had to change my steering rack to a LS1 style due to placement of the steering shaft. Just my 2 cents
Having been involved with two LT1 to LS1 conversions, I would HIGHLY recommend spending the $500 and having John at Speartech make the harness modifications. I spent a year getting everything working properly on my car....not fun.

No I definately plan on having John do it. Already spoke with him about it, waiting his replies on a few questions then it's off to him. Jason, as far as the fuel setup what did you do? The LS1 going into the car is a 98, the car is a 93 LT1 setup. I'm having probs figuring it out, the car is gonna be stock for now mild bolt on. So I don't need to dump a grand in a fuel system for the car to only be stock....
I know this question is for Jason. But on my conversion I just upgraded to a LS1 in tank fuel pump. Since the LS1 requires more fuel press. Then I blocked off the return line since LS1 style cars are returnless.

So you just used your stock LT1 fuel line, that's it to hook it up? Go a lil more in depth because everyone I talk to says I need to spend $500-$1000 on getting the fuel system exchanged to work....
The way I did my fuel delivery. 1. changed my old fuel pump with a LS1 Style fuel pump. What I did was I went down to the local auto parts store and got for a chevy 1500 vortec truck same pump and way cheaper. I think I paid like $80 for the pump. 2. I blocked off my return line right there in the engine bay. 3. I got the fuel line the one with fitting for the intake inside the engine bay off a LS1 car, cut into my line on my car put a connector on it. clamped it down. So now I have the fuel fitting for the LS style intake. That's all I did to get my fuel system working. I stuck a aeromotive fuel pressure regulator on it. But it's not a neccesity.

What style Aeromotive Reg, LS1, or LT1? So you cut the plastic line, got a fitting clamped it onto the plastic line. Then plumbed it to the fuel rails. Do you have some pics? Where in Indiana are you? I'm on the IL/IN border....This sounds like the most promising way...
I wish I could have a 98 LS1 Wrecked somewhere around me, I'd just steal the fuel setup lol....
