Default LSX (5.3) swap

I had a thread I started back in 09 but thought I'd start a new one.

I'll update this over the next few days but I'll start it with the good part.


1st start was yesterday and I got to drive it down the road (about a 1/2 mile or so)!

Now to start working out the bugs.

And yes my car needs a paint job, its had a hard life and paint, new bumper will come!

Nice SRT, that 350 is going to be loud as crap, unless you change that exhaust.

I'll start by saying this was a long project. I wanted to do this without useing a swap kit and made everything my self. Needless to say I installed, made mounts and so on more than a handful of times and wasted more money on parts then I want to count !


My gauge set up, some cheap sunpro gauges in the stock three gauge holder, a speedhut tach and a APSX D2 wide band in teh door vent

In the drivers seat it sounds awesome. Last night rolled into it a little over half throttle and it builds boost so fast, was at 7lbs before I knew it and going 80 in a 45 could have been bad if I would have passed a cop.


CUL8ER I was just looking at yours and damn, now thats a nice clean build!
