Had this vx commodore in for some serious uprgade's just recently.
It was a stock ls1 that had seen better days prob the dirtiest ive seen in a while too.
The good news is it already had a built turbo 400 and converter ready to go. The ls1 was removed, bay cleaned , wiring loom tidied up and in went a rebuilt 5.3 built here in the shop.
This is a budget build but has some good parts in it.

Gt 42 turbo , 4" dump , straight thru 4" dumped at diff atm will be getting a muffler or 2 to make it quieter and rear bar exit.
Aeroflow intercooler 600x300x 75
E boost 2 boost controller.
Also did battery relocation
Moved the astra pump to the boot and used a quick start module and put it on a led switch.
Relocated factory pcm inside the car.
Vz rad conversion
New water pump and lots of other parts.
The only thing that was never going to get us far was the 340 fuel pump but that will be upgraded soon.
The 1st thing was to crank and get oil pressure and then once running a base tune was loaded and proceeded to run the engine in.
With everything going well the oil was changed and filter cut open to inspect and it was all good.
Tuning time knowing the 340 wasnt going to go far on e85 i just tuned on gate presssure and ended up with 418 rwkw on 8 psi @6000 rpm.
I did a run and went 435rwkw at higher rpm but was out of pump.
The idea was to just do a 400kw tune now it can get finished up get some street klms and then come back for fuel system upgrade so we can really see some good gains.
For now its getting a couple things to finish off and the owner can go cruising.
