I was just wondering how they are different and if you had the LS1 kit could it work for the LT1?

 

I believe they are the same kit. If you are talking about the wet kit, they just have one part number for all GM EFI cars. I just put this kit on my car. Excellent quality.

 

On a few different sites they have them as two different part numbers though. LS1#20227 and LT1#20217!

 

They are the exact same kit, except for different jets. I bought a used kit that was on an LS1 for my 94.

 

Well right now I don't know what I have. The reason is that I just bought a brand new Nitrous Express kit on E-Bay for a great price. In the title and description it said it was for all LT1's but the part number that was there was NX-20227. On the NX site it says that is a Race-C5 kit! I'm getting a little nervous as to what I just purchased. I e-mailed him before the auction was over but he said he is positive that it is the right kit. I keep finding different kit numbers for my car but I don't know which is the right one. The latest number is 20920! Can people post the part numbers to thier NX kits for me please or assure me that I am getting the right part.

 

I'm no pro but I can't see you having a problem. There's not all that much to a nitrous kit if your worried you could just buy a set of jets for your LT1.

 

So basically all of you guys agree that the only diffference between kits is the jets?

 

When it comes down to it, just be worried about the jet sizes and WHEN it kicks in.
