LSX +T-56 into......A Grand national. That's right, I am about to attempt and complete one of the most bastard swaps known to man-kind.
I plan on shoving a 5.3 with 6.0 heads into my GN backed with a T-56 and then adding a 70mm turbo to the mix....to keep the boost factor of course
I have a couple of write-ups on this swap, it has only been done a few times so most of the info I am going to be posting here is a "How-to" for future G-body owners that want to complete a similar swap.
Alot of you may wonder why I am doing this to start with, And I'll tell you why. Reliability, cost of parts, wow factor, and of course, drive ability. I want to be able to take this car on a cross country trip and achieve mid 20's Mpg while not sweating that my motor is going to unload at any given time. I also want a manual transmission car, but installing one behind the 3.8 isn't effective at all.
Just wanted to make this thread to let everyone know what my plans were, I should be starting this project in the next 2 weeks. I am using a $9000 budget for this build and plan on buying alot of stuff used.....So i need to get my post count up too lol.
Any questions just ask away. thanks!

Damn man, goin to **** off a lot of people...
**** um
.
I love G bodies, and I love a turbo LS, guess It's a match made in heaven.
However, I think you will grow bored of a 70MM fast.
Why not step it up to something a little bigger?
That 5.3 should have no issue getting that thing spinning.
Can't wait to see some pictures.

Running into some issues already.
I cant seem to get a clear answer as to where i can get a full motor/trans mount kit for the G-body.
Also, am i going to have to shorten/lengthen my driveshaft?
