Sechs Toy 32 Posted November 25, 2009 Report Share Posted November 25, 2009 right i can't sell my mk3 vr6 for love nor money, so im gonna put the engine into my race car for a little bit,when you guys do a mk2 conversion do you retain the standard exhaust manifold, does it fit ok on a mk2?buying a 6 branch manifold, i see them available for the mk3 but not seen any for the mk2, related really above, are they kinda universal?what fuel pressure does the vr6 run at?is there a fuel pump under the car or is it all intank?, (as my race car has a fuel cell so have to make sumit up)many thanks Link to post Share on other sites
LadVR 0 Posted November 26, 2009 Report Share Posted November 26, 2009 The standard manifold fits fine, there's enough room under the bulkhead. I ditched the cat and welded a boss on the exhaust for the lambda sensor.It'll run fine on the existing pump, but it was a lot better when i swapped the vr tanks and lines onto the car. Mine was a valver, just dropped the pump off and the vr fuel filter will fit diagonally on the existing bolts under the car.Also the vr pump being inside the tank its quieter than the valvers being underneath the car.

Sechs Toy 32 Posted November 26, 2009 Author Report Share Posted November 26, 2009 well the only pump i have is a bosch 044 fuel pump, i can ajust the fuel pressure to what ever the car requires hence needing to know what it runs at, Link to post Share on other sites
12vvr 0 Posted November 27, 2009 Report Share Posted November 27, 2009 im pretty sure that a obd1 vr6 has a 4 bar fuel pressure regulator on the fuel rail, im sure someone will confirm wether this is correct!! Link to post Share on other sites
boostjunkie 0 Posted November 27, 2009 Report Share Posted November 27, 2009 yep I can remember someone saying 4 bar and thinking it was alot lol, my Skyline only runs 3.2 bar but it does have 740cc injectors Link to post Share on other sites
Sechs Toy 32 Posted November 27, 2009 Author Report Share Posted November 27, 2009 870cc's on my 20v lol, which will end up in the rolling shell now, yay 600bhp fwd on the road,the vr6 will go into the mk2 race car and remain up for sale, so i can build the dragster Link to post Share on other sites

mattingg 0 Posted April 30, 2010 Report Share Posted April 30, 2010 4bar for 2.9s, 3 or 3.5bar for 2.8s I think, doesn't have anything to do with ODB1 or ODB2. Link to post Share on other sites
