LT1 and T56 Swap into 88 GTA - LTX and LSX - Third Generation F-Body Message Boards

Hi guys im new to thirdgen.org but I am going to be starting a project of putting a 93 LT1 bored to a 355 and a 97 T56 transmission into my car. I know I will need the harness for the engine i believe i can get from JEGS. Then I also know that I will have to grind metal to get the transmission to fit in right but what else will I need for the swap? Will the LT1 be compatable with the t56 tranny?

Also I am buying the transmission alone so will my previous T-5 parts fit with it or will I have to buy newer parts?

Thank You

'97 F-cars had the LT1/T56 - if yours came from a '97 Camaro/Firebird, then it should have no problems.

Why not just get the engine harness from the car the engine came out of?

bought the engine by itself it was already taken out of the firebird, the firebird it was in got wrecked, i dont know where the rest has gone i bought the engine alone

The T56 uses a different slave cylinder than the T5 does, you might want to get a slave and master cylinder for a T56

As Air_Adam said, LT1's came with T56's originally.

Read this thread and then ask questions.

I did fully understand exactly what your asking. I completed my T5 to T56 swap a couple of weeks ago, along with rebuilding the trans myself, and working out the design and machining it for a cable drive. I now offer that service to TGO members. It took a ton of research on my part to accomplish all this, but it was worth the effort and many problems I and others encountered are discussed in great length in the thread I linked to.

I'm asking you to actually put forth some effort and not just post a question without doing the research. Read the thread then ask your questions. There are lots of pics and many questions are asked and answered there, for both a T5 and auto swap to a T56.
