Looks like Greddy is deleloping a kit for the Z and G35
When people talk about about the top tuners in the industry there are many that come to mind, but only a few that stand at the top. GReddy is not only one of those top tuners, but quite arguably the best. GReddy has provided the industry with high quality products that have proven their selfs time and time again, not only making power but meeting the needs of racers and enthusiast a like. So naturally, when we heard about GReddys prototype 350Z we just had to check it out!

.....GReddy has spent countless hours of R&D time working with their new 350Z and has developed a car worth drooling over, by combining some potent products that are making some impressive numbers. Here is their current set up:

2003 Nissan 350Z (Track model)
Color: Daytona Blue
Stock Dyno HP of 260 (peak)
With GReddy Modifications: Currently 345HP (peak) though the factory Catalytic Converters at 0.4kg/cm2 of boost
(They are still tuning in low speed derivability now) (Future Plans are to boost up further hopefully hitting over the 400hp mark)
If all goes well in the tuning, they would like to produce a production twin turbo kit for the 350Z and maybe the G35s.

GReddy:
Prototype Twin Turbo Kit with:
-Twin GReddy/Mitsubishi TD05H-18G Turbochargers
-Twin External Type S Wastegates
-One off Stainless Steel Turbo manifolds
-Twin Airinx AY-SB open element air-filters
-Prototype Front-mounted Intercooler
-3 Row Type 23 (H292 x W600 x D115mm)
-Dual inlets end-tanks to a large 80mm single outlet entank.
Engine Control:
-e-manage (piggy-back ECU)
-PRofec e-01 electronic boost controller and e-manage programmer
-Full Auto Turbo Timer
Exhaust :
-Prototype Full Dual Evolution Cat-back exhaust system (dual 60mm)
Brakes:
-GREX/ Alcon 6pot Calipers with slotted 360mm rotors (light-weight)

Others:
Injectors:
-RC Engineering 440cc Injectors
Suspension:
-Tein HA Coil-over suspension kit
-Tein EDFC damper controller
Wheels:
-Volk Racing GT-C Gun-metal F 19 x 8.5, R 19x9.5
Tires:
-Nitto 555R F 235/35/ZR19, R275/30/ZR19

With their busy schedules we got a chance to squeeze in a quick interview:

Club350: Mike thanks for taking the time to answer a few questions that I’m sure our readers would like to know.

GReddy: No problem.

Club350: What would you say is Estimated HP of the car (Current) ?

GReddy: Right now power is at 345hp @ .4kg/cm2 (though the factory Catalytic Converters) Stock was about 260hp

Club350: 85 hp gain, that’s pretty good. What would you say is the estimated hp after tuning?

GReddy: TBA maybe 400hp on our test vehicle (but 340-350 for a base kit).


Club350: 400hp in the Z would be sweet. What do you believe is the max potential for the stock block (HP)?

GReddy: Hard to say at this time. We're still testing to see.


Club350: Describe the difference in driving over stock?

GReddy: You can definitely can feel the added boost in seat while driving. Very noticeable difference in power.


Club350: I heard the install is difficult due to lack of space. Is it?

GReddy: Currently we are work with a prototype, which was pretty tight, but it is still too early to say how a production kit may be, we may end up using actuator style turbos.


Club350: What is involved in the kit?

GReddy: TBA, currently in addition to the basics like the manifolds, turbos, air intake, intercooler and piping, there are larger injectors, and our e-manage piggy back ECU.


Club350: What do you believe the estimated 1/4 mile times will be?

GReddy: That is very dependent on suspension, wheels and tire set-up. But you figure there is an additional 85hp.

Club350: That’s true it is very dependent on a lot of other factors besides power. Will there need to be a tranny upgrade (ex clutch, or shift kit for auto)?

GReddy: Currently it is for manual transmission only. So far our clutch and transmission is holding up fine.


Club350: I know all the CA drivers want to know this, but will your kit be carb legal in all 50 states?

GReddy: Again it too early to say, but we would like the kit CARB exempt. We are trying to work with all factory emission hardware. It really depends on further testing and tuning.

Club350: What do you believe the Estimated Price range?

GReddy: Its way to early to say. That would really depend on final parts, and total R&D time.


Club350: On a scale of 1-10 with 10 being the highest what is the chances of the kit being offered to the Z community?


GReddy: Right now I would say 7

Also Power enterprises

 

I have no idea? Just something I found on the Web. It's interesting though how much aftermarket support is developing for the Z and there are many, many companies coming out with FI that will hopfully fit our cars.
Kits will be very expensive as just slaping a couple of turbos won't do it. Injectors, ECUs, exhaust all need to be changed as well. Its a mod I'll consider in 3.5 years when my warranty is up.
