This is the story of my project that has taken every ounce of energy and patience I have had. as far as I know, I have the ONLY 6-speed, LSX swapped GN out there.
bear with me, as this thread is copy/paste from another forum I am on. SO ignore some of the comments LOL. From start to finish, enjoy
PROJECT STARTED MARCH 17TH, 2010
Some know, but some dont. So here's my build thread.
I took $10K out of savings to do some mods to my Buick and after some long hard thought and may discussions with fellow car enthusiasts and engine builders I have known for a while, I decided that it was time to make the shift to an LS power train.
Lots of people have done LS swaps in G-body cars, but few have done them to ACTUAL grand nationals and I will be the first to be putting a 6 speed in one.
Plans for the car include a forged 5.3 with 317 heads, pushing 15#'s of boost with water/meth injection backed by a T56 from a firebird. I have almost everything needed to do the swap and i will update this thread along with the 5 others on various boards that I am on with this build.
The goal for this car is 550 RWHP, I am not trying to get crazy with it since I have the six speed. i want something fun to drive on the weekends and I miss having the reliability and gas mileage of the LS1. If you don't like what i am doing to MY car, please press the back button and keep your negativity out of this thread. thanks.
