My engine build project

I posted this on my350z but thought I would share with my G35 friends as well.

Thanks to Sharif, Devon and Chris at Forged Performance for an outstanding job on my car and of course thanks to Sandy and Sharif's dad for helping with my travel arrangements. They are all very friendly, professional and do quality work. Also, thanks to GT Motorsports for a fine job on the short-block.

Okay, the project. I spoke with Sharif about building the short block for a very reliable, "bulletproof" 500whp (DynoJet). I had been running the Greddy TT @ 8psi on the stock block for a year with no problems. The previous "uncorrected" number was about 355whp. The main reason for the 500 goal was due to the limits of the 5AT transmission. We had already upgraded the valve body but also knew that, until upgraded clutch plates and a rebuilt trans is available, this would be testing the limits.

My goal all along for this car has been a balance of show and go. Here is a breakdown of the car and parts.

Greddy TT 5AT
20" Maya GR5 wheels
255/30 front and 305/25 rear Conti SP2
Do-Luck bodykit

Engine:
Arias Extreme Duty 9:1 Pistons
Pauter Billet Forged Rods
ARP Rod Bolts
ARP Extreme Duty L19 Head Studs
HKS Metal Head Gasket
NGK One Step Colder Plugs
RC 1000cc Low Imp Injectors
Nissan Rev-Up Oil Pump
Aeromotive FPR
AAM Oil Pan Spacer
Tial 1.0 Bar Spring
AAM Downpipes w/open dumps

Cooling:
Koyo Radiator
Stillen Oil Cooler
B&M Trans Cooler
Nissan Rear Coolant Bypass
Jet Hot Coating

Electronics:
HKS F-CON V Pro
HKS Knock Amp
HKS Twin Power DLI II
A bunch of HKS sensors

Suspension:
TEIN Flex Coilovers
(switched from TEIN CS for more stiffness)
Wheel Alignment

We also has the turbo piping chromed and the timing cover black powdercoated.

Numbers: (for now)
459whp / 450trq @ 12.5psi on Dyno Dynamics - no DJ correction.

Sharif was only able to get one good dyno run due to issues we are having with the auto transmission. We believe the issue is that the torque converter is locking up under heavy load. Not really sure until we drop the trans for a rebuilt one. There seems to be some developments forthcoming and hopefully we'll do a rebuild for more boost and power.

The car fires right up and runs very smooth. When you punch the gas @ WOT all hell breaks loose. Even with the 305s in the rear the tires are roasting in 1 and 2nd. When cruising around 40-50mph and then punch it the 5AT downshifts very quickly to 3rd and you get sideways. The power is very smooth but man those open dumps are crazy. With the exception of the trans, the car just feels perfect.

Here is a link to the thread. I'll copy over the dyno sheet when Sharif posts it up.
