Hey everyone I'm Kevin and don't exactly have a Maxima but have the motor

. It's a 2002 SE-R Spec V with the 5.5gen VQ35DE swap. It's been in the car for about 2 years and now I'm getting ready to work on a build. Wanted to set up a thread to get some feedback and what not or to show other what they may be interested in doing to their motors.

Everything is on order and on the way for my build. I'll be upgrading some parts while I'm in there as well.

Last dynoed at 250hp/268tq.

Short Block :
Wiseco 96MM (.020 over) 11:1 High Comp Pistons
Eagle H Beam Rods and ARP Rod Bolts
ACL Thrust Washers/ACL Rod Race Bearings/ACL Main Race Bearing Set
350z HR Head Gaskets (need the machine work done for compatibility, shouldn't be very difficult a shop did it for a Z owner for around $80) (better coolant flow)
ARP L19 Head Studs and ARP Main Studs
350z Revvup Oil Pump (stronger)
OEM Gasket Set
Machine work to bore/hone and balance everything. With zero balancing the underdrive pulley etc.

Heads :
JWT C-2 Cams and JWT Valve Springs/Retainers
Headwork = Full port job maximizing flow
M2 Serdi Valve Job - 3 angle cut

(These flow numbers are before the serdi valve job, so expect an even larger increase in CFM 10-18CFM more should I have flowed the heads after, we just ran out of time the car is already almost done being reassembled!)

Stock - 188.8 @ .200"
281.2 @ .500"

Ported - 228.9 @ .200"
318.7 @ .500"

About a 37.5 CFM gain, which should be around 50hp on the top end and you can see there 40.1 CFM gain on the low. So if each CFM = around 1.4 HP you can see that the headwork alone will post around a 50hp increase

Intake setup: Intake manifold full ported, & SSIM done.

Tuning : Standalone

Misc :
JWT Flywheel
Unorthodox Racing Crank Pulley Underdrive
NGK Iridium Spark Plugs
6th Gen Maxima (2004-2008) Replacement Valve Covers (these help prevent a vacuum/oil leak over the 02-03 valve covers)
Walbro 190 Fuel Pump (already installed)
JWT Clutch (already installed)
NWP Thermal Intake Manifold Spacers (already installed)
Exhaust, Headers, Cold Air Intake (already there)

Nigel at Premiere Performance in Pembroke Pines will be doing the assembly
Larry at South Florida Crank will do all the machine work.

Here is what it looks like as is.

Goals : To achieve as much HP as possible on the VQ35DE motor! Way above the 300HP range with the tuning =).
