Got the vvti coil pack conversion done, and it's no good. I can't boost past 21psi. Looks like I need to do the LQ9 conversion, because more spark. So yeah, I'm pissed that I wasted my time doing this, but if I do the LQ9 setup I should be done, forever. I will probably contact Mojo and see if there's a cheap option as I don't need his bracket to hold the packs, and I already wired everything for the vvti setup so I think I can just add 3 more connections for the extra 3 coil packs and get them working. Or just rip out all the stuff I just did and do his full harness, it might be better in the long run.

Installed the DLI and it helped. I am able to hit the 28psi now, but it's not enough. So it looks like LQ9 conversion is next. Going to order the harness from Mojo tomorrow and the spacer from Rosario Racing. 


So if the spacer is good enough, I will have 2 sets of VVTi coil packs and an essentially new HKS DLI for a Supra for sale.

Cleaned up the car. Going to be changing out the oil, fuel filter, fuel pressure regulator, and headlights tomorrow. I've been having a fuel pressure issue. I changed out one of the fuel pumps yesterday and swapped positions in the tank to see if the pressure was fixed. It wasn't. So I will change out the Aeromotive A1000 regulator and Aeromotive fuel filter as the filter has never been changed. The headlights are being swapped out to JDM Soarer lights that I had professionally modified with bixenon projectors. They looks so clean and were expensive. They will help on my drive to NJ next week. I also had the rear tires changed to Mickey Thompson Street Comps and sold the Nitto NT05R's that I had before. 


I am selling my stock headlights. So pick them up if you want a very clean set. 







Tire photos were before I cleaned the car 







Also had my valve covers redone, since the coating was chipped all over the place.
