Just got them last week, they are made by Jenvey, 45mm bore, 30mm tall. They're very compact and feature an ingenious lever and spring system which is very compact too. The levers currently face up but the bodies will be turned around so they face the engine, clearing the plenum floor for a low profile. The 2 banks will have to be preciously matched and I have yet to find a way of doing so. Some modifications to the lower manifold are required.

 

Typical add on is the increased runner lenght, up by 50mm since the original plenum floor also serves as the runner end and the extra 30mm and 19mm from the velocity stacks + the new plenum floor (5mm) lengthen the system. This is in fact an improvement over stock since the stock system is extremely short. Nissan tried to compensate with a variable plenum design for the vg30det.

 

 

 

 

 

 

The engine will see 2 Porsche 996 turbo's along with custom manifolds. It already has ARP head studs and Tomei steel 1.2mm head gaskets. I will probably also have the low end done with forged JE pistons and Eagle rods. Cams may be used if required.
