Update:


I've been having issues with ignition lately. I've changed the spark plugs and wires, no fix. Seems like the HKS DLI has gone bad, so I've been researching my coil pack options. I was set on the LQ9 conversion, but can't run them since they hit the intake manifold. VVTI packs seem like a viable option as well. 


But then I asked First State Motorsports and they said to get the Okada Plasma Booster. So I think I will. It's just 2 wires and should be comparable to the HKS DLI I have now. I will order it tomorrow and install it this week and see if it works. I've been stuck around 23psi since anything above that causes issues. Trying to go up to 35psi and hit 850whp hopefully. We will see.


On a side note:


I've been running around for weeks and doing logs in the car with the AEM, and would make fuel adjustments but it would never adjust to the range I want for WOT. My friend was messing with the map and hit optimize fuel map, and boom I can make .01ms adjustments now instead of the huge .07. So now I can get my AFR's right because I have a finer control of the fuel adjustments. I have to fix this ignition issue and retune and dyno. Maybe even a little drag strip, but this clutch is horrible at everything and I want to get a twin plate now.

Changed the oil today. Mobil 1 15w50. Motor seems happier now. Gonna stick with it.


Still waiting on the plasma booster to show up. Waiting sucks.

Started pulling the car apart to start the VVTI coil pack conversion.


I've order a lot of things and received most of it. I replaced the boots on the coil packs. The wires I ordered were in the right box, but wrong wires, so I will have to send them back to Rock Auto and get the right ones. 


I also got the shortened distributor cover and installed that too. Now I have to wait for the ignitor connector and coil pack connectors to come in and then I will start wiring it up.


Anyone know of someone that makes VVTi coil pack mounts or brackets? The coil packs sit on the spark plugs but are wobbly. It would be cool if there were a metal bracket for them.
