ça pourrait être un montage intéressant.
Mais pas de collecteur pour un 4 corps, dommage...

This is an Experimental Engineering intake manifold for the Nissan VG30I, VG30E, or VG33E SOHC V6 engine. It accepts a 350 or 500cfm Holley two barrel down draft carburetor. I originally developed this intake manifold for the VG510 conversion. Many vintage car owners prefer to modify the body shells of their cars as little as possible. By running one of these intakes with a carb no additional wiring or plumbing is required when doing a VG conversion on a 510 or 240Z. An electric fuel pump must be added but the stock fuel supply line works fine and no return line to the tank is needed. The last picture shows one of these intakes installed in a 510 with a Holley carb and Saudi VG30S distributor: Nice and simple, the way 510s are supposed to be!
This manifold was built from a stock Nissan TBI intake manifold. The top section of the original casting was milled off, the center bore was enlarged, and holes were drilled and tapped for the carburetor adapter. It was then bead blasted and thoroughly cleaned. The fully machined billet aluminum adapter was permanently attached with four grade 8 socket head cap screws and fuel proof metalized epoxy adhesive. There are also two existing ports in the manifold that are plugged with NPT plugs and sealed over solidly with the same metalized epoxy. The ports for a power brake booster, PCV valve, and vacuum advance have not been altered. The carburetor mounting holes are 8mm x 1.25 so you won't need an SAE wrench to work on your metric Nissan.
For street use or nearly stock engines I highly recommend using a 350cfm Holley or Demon carburetor. The 500cfm carburetors do not meter fuel well at low rpm with an engine of this size and have transitional mixture issues that are very difficult to resolve. Driveability is much better with a 350cfm carb and it will make more power than a 500 on an engine with stock heads. Even with serious port work and radical cams the 350 may very well make more power.
I have never dynoed an engine with one of these intakes installed so I cannot say how much power they make. I have raced several other VG510s that had stock EFI and beat them all. Two cars had Z31 injection and one had S12 injection. This is not scientific and I do not claim it to be. All of the cars involved were very similar in weight, gearing and tire size and the engine in my VG510 is an internally stock VG30E.
VG30s use rubber inserts retained by steel plates for intake manifold gaskets while VG33s use thin, single-layer stainless steel gaskets. Since this manifold originally came on a VG30 you need to use VG30 intake gaskets to insure that the intake and water ports line up regardless of which engine you intstall it on.
Core policy: Because this intake manifold was built from a stock TBI core I require the purchaser to ship me a good condition VG30 TBI intake manifold prior to my shipping this part. I do not charge a 'core charge', I simply hold the intake until the core arrives and is checked for damage. If you do not have a TBI intake core to ship you may have a wrecking yard ship one directly to me. VG30 TBI intake manifolds can be found on '86.5-'89 Nissan pickups and Pathfinders. These are easy to spot in wrecking yards as they are the only Nissan V6s with a large round air cleaner centered over the engine. I only need the bare manifold casting but am happy to remove the studs and any other components that are still attached. Do not attempt to remove either of the pressed-in steel tubes!
This is not a legal Pro-Six Racing Series manifold. The ones I produce for this series are slightly different to insure they all flow exactly the same. Pro-Six manifolds are serial numbered to insure everyone in the series is running a legal part. If you are a Pro-Six racer and need an intake manifold please contact me.
This intake manifold is not legal for use on emission controlled vehicles anywhere for any purpose. It is intended for use off-road or use on an emissions exempt vintage car that came with a carburetor from the factory.
