Jamin Posted November 7, 2008 Report Share Posted November 7, 2008 hey all, i have been reading in some past forums and some one mentioned that the vl and the r31 engine are slightly different i was having a disscution with a mate who owns a vl the other day and he sed they sound different because a longer exhaust is this true? and i thought it was because more valves in the skyline or something :) ha ha (vl 12 valve head r31 16 valve head) thats what i thought Quote Link to comment Share on other sites More sharing options...

Des Posted November 8, 2008 Report Share Posted November 8, 2008 (edited) Different tappet covers and wiring, Thats all i know of. Exhaust would be a bit different as the shape of the floor is different between them but i highly doubt that will make a difference.

Bowler Posted November 8, 2008 Report Share Posted November 8, 2008 12 valves into 6 cyl = 2 valves per cylinder... 16 valves into 6 cyl (?) = ...2.667 valves per cylinder.....ummm.... Quote Link to comment Share on other sites More sharing options...
machg Posted November 9, 2008 Report Share Posted November 9, 2008 There are a couple of things different concerning installation of engines. In an R31 the cooling system was designed with the engine, in a VL its a bodged up job to suit the styling of the car. VLs make slightly more power, R31s make slightly more torque.

ke30dude Posted November 12, 2008 Report Share Posted November 12, 2008 But if the rb30 is in a vl with cut springs you can get away with thainking you are the best drifter in the world. Quote Link to comment Share on other sites More sharing options...

ke30dude Posted November 13, 2008 Report Share Posted November 13, 2008 saw a regular drifter on the street a few years ago he had a vl didnt do too bad I had a burgundy auto one, it was really good at getting sideways, that was until I lost it and it went hard into the gutter on the other side of the road. The diff was hanging out the passenger side by a good 5cm and the drivers side was driven well in. Also had a bent axle. lol. Quote Link to comment Share on other sites More sharing options...
furryfrog Posted November 13, 2008 Report Share Posted November 13, 2008 They are the same internally In the R31 it made slightly more power. Also the GTS1 and GTS2 again made more power both had different exhausts, cams and i believe the gts2 even had a piggy back computer. Also in the vl s1 and s2 blocks are different, you want the s2 for turboing as the oil feed/return and water feed/return just have bungs in them. s1 motors you need to drill and tap.
