That looks much better. You said you didn't have too much trouble with drive-ability before. Can you feel the difference on the road?

It's got twice the horsepower at 4500rpm! That would be a massive difference

Hi. Yes it drive better, feel faster again. But still room to improve:)  response feel like N1s on 2.6, but a lot more power.

That's right. 250hp different on 4500rpm. I feel I need better tires, 2nd gear car shift lane itself when full boost:(

Original setup made 354rwk @ 24-25psi.

  • Haltech Platinum Pro
  • N1 manifolds
  • -9s
  • HPI dumps and 3" front pipes
  • Full 3.5" exhaust after merge, catless
  • Big K&N pods in partial enclosure.
  • E85 with 1000cc Injectors and 460lph walbro.
  • Cam gears, 
  • Twin turbo pipe mod
  • Plazmaman 76mm Intercooler

Added/changed.

  • BC Springs
  • Kelford L182A Cams
  • Delete pressure valve in fuel line in tank. 
  • Aeroflow fuel filter.
  • Rewired fuel pump with higher gauge wire after realising the current wiring was 15amp max and the pump can draw into the mid 20s. 

Fuel mods done as fuel pressure couldn't keep up. 

Now peaks at 23-24psi but tapers off to 21ish. I think these turbos are out of puff now, but not a bad result for -9s. Pretty happy given the bay looks fairly low key.

390rwkw on N1s? 

Even with a 2.8 and Cams that seems very high for those turbos?

The plates on the turbos were 14411-AA403. I didn't think it would put down those numbers either, but the car put down 495hp on the first run and then we turned up the boost just a little more.

Sorry missed that.

Maybe someone else can comment, is a 2.8 and Cams enough to get that number? I'm assuming they're Type B's so around 264 duration. 

19psi is not a lot of airflow from N1s. 

Must be nice to drive :)

I don't know which cams they are, when the car was listed for sale in Japan. It stated tomei 2.8l stroker kit with tomei poncams with cams gears. Though the tomei ecu causes the afr to drop into the 10s underfull boost. Going to switch to a platinum pro. I expected quicker spool with the N1s, might get better numbers with timing adjustment.
