Honestly I don't think there is a better 1K I've ever spent on this car. It's incredible. Of course I've built everything but the ignition, and the cutout just didn't suit my taste, so I went with the Pettit Dual.
I can't believe the difference. Before the 335's would spin alittle at the top of second, and I just installed everything last night, and just about wrecked the car because 2nd gear was just totally worthless. ET streets here I come.
Just thought I would let people know that if you are planning on the 20+ psi setup, the HKS is really nice.

Jeezus Ralph..that's some rubber on the back. with 371 rwhp, I'd think your trap speed would be a little higher though. I got the HKS twin ignition and love it as well, smoother and seems to have a better toe-in response.
WOT can't tell a difference though.

I had trouble with ignition once I turned up boost with the twins to 14psi and a bad o-ring. Bad idle also b/c of the water leaking into the engine.

Twin power cured that problem. Started every time, even when the front rotor filled up with 3 or 4 ounces of coolant.

 

The HKS TP is a great mod. I got it because I was getting high rpm break-up/hesitation. The HKS TP cleared it right up. The car feels more responsive too. It's super easy install(10Min.)

 

ralph i thought you were parting your car out?

 

yeah well we will see.
I thought I was, but everyone was low balling me on the crucial parts that needed to be sold, so I gave up for now. LMAO The trap speed 109 is with the stock twins just for reference. Still haven't made it to the track with the new setup. Love the HKS though. Also pettit makes a nice exhaust. Sounds good, and doesn't give a ricey look. Still debating on the V8 though. standard ls1 and spray it, and easily in the 10's. Just depends how far this engine gets me. 400rwhp on the street is alot of fun though. it's got that 3rd gear roll of "Hummm get ready it might step out on you" LOL....
later guys
