CJ Motorsports VHR Intake Manifold

BGTV8 · 05-21-2015, 05:46 AM

Dude - this is all done .......... lookie here:

Manifold : Manifold Nissan VQ35 -SF - Jenvey Dynamics

If I was interested in looking closer, I suspect this is the pattern for 1Slow's manifold, except that he installed spacers in place of the ITB's and CNC machined a f4rking great plenum for each bank and plonked some 75mm TB's from a Maxima in front of each.

Ummm yeah... This is meant for a cable driven car and not drive by wire... which means you would have to go standalone ecu and revert back to cable driven system. We have known about the jenvy kit for some time. thanks for pointing it out though.

Speaking off topic for just a second. I heard going to a standalone for ours cars, would not allow our cars to pass emission's?

You are correct. The current standalone ECU's do not offer OBD2 Support. Hence they have no OBD2 port.

Emission Testing for OBD2 (1996 and later vehicles) requires the emissions tester to plug into your OBD2 port and run diagnostics. Without the OBD2 port you cannot physically pass emissions.

Wired and installed accordingly, you would be able to pass an OBD2 inspection.

Although, you dont have to worry about standalones, there is no true standalone that is proven and tested capable of running the VVEL system (not that I have seen yet). I am sure someone could spend a fortune and get a Motec to do it, but I am not aware of it ever being done.

Dynosty can set you up with a Haltech PnP piggybacking the stock ECU, it will run standalone fuel and ignition tables, with the stock ECU running VVEL and OBD related stuff, and shouldnt have a problem passing emissions.

Something I could look into if I ever max out the use of uprev.

The only thing the same about them is they look similar because we originally were buying jenvey throttles for our itb setup. The runners are different. Jenvey runners do not fit the vhr motor

Actually, Jenvey now supply a stepper motor retrofit kit for their ITB system, so you are not forced to go back to a cable to pull the throttle.

One of my race buddies has a Jenvey DBW kit running on a 5.6 litre TVR Tuscan racer here in Oz, all controlled by a Haltech Elite ECU - is early days yet as the Haltech is still a tad buggy, but it is the way of the future as we have total control over throttle position, ignition and fuel and with yaw sensor and steering angle, the next step is driver alterable traction control strategies.

FYI, Motec are already controlling VVEL with M1 series ECU on the VK50VE engine.

Aem infinity is more impressive than the haltech to me.

Fyi that motec unit is still $16k in parts

Nope. I need to find a sugar momma.

Honestly, I think it may be better to have a manifold that keeps the torque the same and utilizes high end HP gains. This would greatly benefit those with high HP FI builds, either stock or built. People would be able to hit higher numbers with the higher HP and same or lower torque and that would keep reliability up.

IMO, a little bit of torque wouldnt really benefit anyone for the money they will spend on the manifold, especially in the low 300whp ballpark.

Punk could you have custom throttle bodies fitted to the manifold (special request). I would like to fit 68-70 mm to the manifold and do custom 3 inch intakes with velocity stacks.

phunk · 06-01-2015, 02:00 AM

You might want to look at what the GT-R guys are using. Since the throttle flanges are the same, you could use some aftermarket GT-R throttles. I wont be playing with the throttle bodies.
