Natural Progression of an LS swap

I figured I'd just leave this here.

I did the LS swap 2 years ago, made my own mounts, pan, and wiring harness. Matt did us all a favor by making quality swap headers.

Engine:
LS2 Bottom End
Eagle Rods
Wiseco pistons
LS3 Heads
BTR Valve Springs
Trunion Upgrade
TickPerformance Custom spec'd cam from Martin

The car makes 425hp+150shot of nitrous as it currently sits, but naturally more is on the way.

I'll let the pictures do the talking.

This is currently in the works. Hood shuts no issue. This is going to be fun.

Looks really clean sir! I like the way it sounds too, could you share a pic of your exhaust too? Mine seems to be a little louder than that hahaha.

That's a CTSV supercharger correct? Are you going to be able to use your LS1 accessories or will you have to change it out for a different set?

My IS300 - 5.3 LSx swap and Turbo, KWv3's, bushings, sways, wheels, flares, scoops, lots of tire smoke and 620 whp and 650 torque - tons of parts and so much time.

Good stuff, clean looking work. I spy a Supra in the background. How do you like the LS versus the 2j?

I am considering a V8 swap... I have a few questions...

1- Did you remove the entire stock ECU and harness? I am considering deleting ABS, traction and all that stuff.

2 - How does your fuel gauge work now being that the ECU makes calculations to adjust the needle.

3- Were you automatic or 5spd before the swap?

Modified the upper rad hose this weekend so I don't have any interference with the throttle body. Hood still closes with the nitrous plate. I might have to trim alittle bit of the hood bracing once i build the intake.

I'll be building the Heat exchanger coolant tank this week.

Two completely different motors, the 2j feels more refined.

There is no stock lexus ecu in the car. I pinned the GM ecu to the corresponding Lexus circuit. ABS is controlled by the factory is300 abs ecu.

2 - How does your fuel gauge work now being that the ECU makes calculations to adjust the needle.

Fuel gauge still works its just not as accurate as it was before.

Factory 5 speed car prior to the swap. The t56 fits almost as if it belongs in the car. I had to trim maybe a 1/2" in the front of the shifter opening.
