Fired it up for the first time last night. Everything looks good so far. Hope to be on the track yet this fall to start the sort process.

Hi, Mark! Thanks for the great info about this tranny/engine. I have Isuzu T5 in my garage and I'm on the market for GM 1.4. Do you actually get your wiring from http://www.enginewiring.com? I gave them a call yesterday and they can't help with this engine. How you manage to fired it up? Any tricks and tips? Thanks. Victor.

Enginewiring.com did mine but it took them a long time to get it done. Not sure it is a high production project for them as they seem more interested in LS engines, etc. Stripping down the harness is not impossible to do, it just takes patience. If I had it to do all over again I would have just done it my self and save a few hundred bucks. The trick is to get the Factory Service Manuals for this motor/Cruze 1.4 for the year motor you have. I'm not big on electronics at all but I ended up revising the wiring a bit by adding a VSS to the harness/PCM. The trick is getting the right tools and the right connectors. YouTube is a wonderful source on how to modify a harnesses for Chevy engine swaps. It can seem overwhelming but once you figure out how the read the factory manuals it makes sense. Everything you learn along the way will be helpful when you have to troubleshoot if something goes wrong.

As I said before, one thing I did leave to a pro was the programming. Overriding the factory programming codes and get the motor to run takes a lot of experience. Without programming knowledge the motor is a large paperweight. Jerry Kinney at Bad News Racing is THE Guru. He has done several using the HP Tuners system. Not cheap but worth it for a custom stand alone engine tune. He had mine running within minutes over the internet on my computer. He was in Florida and I was in my garage in Indiana. Technology can be amazing.

I just wanted to say thank you!

I'm in the process of getting and starting an LTG ecotec repower and some of your links are really helpful! Some of the mods and tuning are a black art which is very frustrating..unless you want to spend $2200 on the gm ecu :/.

So I run mustang T5's in one of my road race cars and have a few parts in inventory. I bought the unicorn Isuzu trans and bellhousing (2 actually, one locked up and one in awesome shape).
Unfortunately there are a few differences on the input side. I have not checked the output side other than shifter location.

Shifter placement: Fox is 19.75 and Isuzu is 18 (from front of trans)
Pilot Bearing Diameter: Fox is 0.677 and Isuzu is 0.599
Bellhousing Register: Fox is 4.914 and Isuzu is 4.685
Input shaft length: Both are very close to 7.125 (using tape measure, no calipers or depth gauge big enough)
Spline count is obviously different also

The front bearing retainers are the main differences. While it is possible to machine the Isuzu bellhousing to fit the fox bearing retainer I do not have the release bearing components to check and see if they work.

The cases do have the same bolt pattern so that is a plus.

I am hoping that I will be able to just put the Isuzu bearing retainer on the ford trans but it probably wont fit. I will keep you guys updated when I have time and space to tear these apart and check everything out.
