I modified the chassis harness and dash harness so that theres no fuse box all there is in the chassis harness is headlights, blinkers, ignition switch and tailights also radio

but I modified the ls1 harness with relays and fuses for the injectors and coilpacks which are located in the car. corvette harness with 5.7 gto pcm. corvette pcm plug has be re-pined to GTO pcm, only reason I did this so that I dont have a problem with the corvette drive-by wire TB.

nice! that is very similar to what we will be doing. i'v been scoping out these builds for a few days now and was ever so happy to see yours considering we will also be doing our swap in an early s chassis. we currently have a 600hp compound rb20 in the car now, but will be adding 2 cylinders, a big single turbo and hell of a displacement increase. i'd like to see more of your build!

Yea finally starting to cool down, I was thinking of solid rear end, but instead I put in a q45 rear end. Diff (3.52 final drive) driverside q45 axle (beefy guy) r33 skyline or 300zx tt driverside axle and the q45 hubs because there 30 spline and stock ones are 29 spline.

The benefit to this rear end is that theres ppl out making 800-900hp and with the stock rear end with beefy axles they were still breaking stuff, but with rear end not only do you get better gearing for high power but it can take alot of power most ive seen was a 1200hp 2jz 240sx with a q45 rear end and it still holds up till today (I think lol). plus it only cost me $300 bucks and it was all bolt-on. Ill take some pics.

Question: those look like low impedance injectors and you are running a GTO pcm?

sure have just not with the LS yet, I drove it with that rear end set up with the turbo VG30 still in the car, and I must say it feels 10x better than the stock z31 rear end!

yea I know once everything is mocked up and done, Im gonna take everything back out and re-paint the engine bay. I tried to connect the stock 240sx throttle cable but it wasnt opening the TB all the way, am I doing something wrong?

the car is a orignal kouki so kouki front is going back on, but Im looking for some headlights.

Are you on zilvia atleast lol. They are always headlights for sale their and u need to search up how to run the stock cable. What u need to basically do is strip the plastic covering off the throttle cable where it come out the firewall to get more slack from it. Check on silviav8forums.com there is a write up on their. It works great for me i havent had a problem .
