GTM Build log.

Next few months was collecting parts. The largest departure from the norm was the engine. Turbo 5.3..........

I am using a 2005 aluminum 5.3 L33 that I purchased locally with everything needed for $750.00. I sold the LS1 donor engine to recoupe some of my costs. This 5.3 comes stock with the 243 heads. I have purchased a 216/220 exh .525/.532 cam w/918 springs for $257.00 nearly new. So all said and done I have a 2005 29K motor with 243 heads, small cam (about 50whp increase), 2005 (newer) electronics and around 370-380 na hp for just over $1000.00. I will also be running a MP70 turbo with a dual switch 6/12psi boosting output to 500@6psi or 650@12psi. I swapped all of the drive accs and the oil pan over before selling the LS1, the buyer was fine with it since he was putting the motor in a gen3 Camaro (the clearances are tight in the engine bay of the GTM, so the Vette stuff needs to be used) the truck acc will not work. The L33 was a baby LS2 used in short bed 4x4 trucks for only 3 years, as a test bed for some LS3 ideas they wanted to test. Here is how it looked when I got it.
