LT5 swap

[Clean87TA]

How it going ladies and gents.. first of all I’m new to this forum I’m always on Ls1tech. I’m here because I need your help. I just recently traded an Ls1 setup for a complete good condition LT5 outta of a 94 ZR1. It’s complete minus the ECU and flywheel clutch set up and transmission. So first question I have an Ls1 T56 outta of a 4th fbody from the researched I’ve seem that I would have to swap out my input shaft, and also one hole on the bell housing doesn’t lined up. Is there a solution beside swapping over to a ZF tranny? Unless some want to trade.. and also were can I get an ECU? Any sponsors venders here? This engine will be going on a 3rd gen trans am thanks in advance!

Umm.....


I may be wrong....but an ecu might be a problem. I think your best bet there is calling Marc Haibec.

Is that because they are hard to come by or?... I’m just doing my research before I go knee deep into this project

Frank’s right
Because you don’t have all the vehicle interfaces to worry about you can go with a more modern aftermarket ECU like from DIY

Do you have someone building a harness for you? LS engine swaps have spoiled people when it comes to late model engine swaps. The LT5 is going to be a lot more work. Also, keep in mind, you're going to pay 2800 for a megasquirt ECU from DIYAutotune. And I would look for a ZF as I think you'll have as much into adapting a T56. A used ZF is going to cost you around 2400-2800.

Do yourself a favor and speak directly with the guys at DIY Autotune. They are quite familiar with the LT5 and can probably fix you up with a lower cost engine control unit that does not include all the extra features and input/outputs necessary to make it compatible with the ZR-1 Corvette.

They are good to work with. They can build him a ZR-1 ECU. It exists and numerous people have bought them. It's just not a stocked item. I got mine for around 2400 as I recall, but there were three being built at the time. They quoted either 2700 or 2800 if mine was the only build.

I don't think there would be any cost savings in adding work to remove features that are really just part of the programming, which already exists. They still have to use the same hardware.

For this project he wouldn’t necessarily need the the special case and harness plugs like DIY provides for C4 ZR-1 backfits 8142

The plug may save a couple bucks, but it needs a case regardless. No matter how you look at it, it's over 2000. I was just giving the OP an idea of cost.
