Oh its just hard as the RB20 conversion gets a fair bit of slander as its performance can be somewhat lacking in a VL body.

Oh its the old adage of getting the VL turbo'ed cheap, but personally to make them work you need 4.11's in the diff, a higher than normal stall if its auto and a little extra boost to make them ok'ish. By the time you do that you may aswell of just converted a n/a motor properly and it would probably go round the RB20 easily. Still they like a rev and can be good fun so not all is lost. Meh just an opinion, but then again I like my cubes above 400 so I may be biased.

You need to use all the VL manual stuff, tailshaft included. They go ok for what they are but the lack of torque is noticable. The one I put in my old car to sell ran a 13.7 with only an intercooler and 3" exhaust. No boost controller fitted. 4.11 diff gears are a must
