im loooking at picking up a rb20 powered vl today but just need some info if anyone can help me out i need it kinda quick though i tried searching but info was limited i know the rb20 is a hand grenade in high power applications like 350 hp range but what if its pumping a claimed 220 hp at the wheels and how strong is a rb20 5 speed my mate reckons i should not buy the car because of theses two reasons ?

Ive had a rb20 powered vl, personally i would never buy one again. Save your money and get a RB30 powered vl.

did you have issue any info cheers

Save your money and get a RB30 powered vl. spot on save your money the RB20 box is pretty weak, most people with high powered RB20's replace it with an R33 box it would be a lot easier (and probably cheaper in the end without repairs etc) to just save a bit more coin now for an RB30

Most people that have owned or driven an RB20 powered VL - do not want to again. There are some that seem to like it, but it will never feel the same as a 25/26/30 powered VL. The VL weighs 1300kgs - you need more than 2L to get it moving.

The RB20 box is about as strong as glass The RB20 engine is about as good as getting aids. If it was the cheapest VL in the world.. maybe I would think about it.. but only to rip the RB20 out of it and put in a 30T Some original photos have not been recovered yet.

na its not thye cheepest but has all the fruit tuxedo black over silver calais leater kebab spek interior 19 inch wheels

Obviously not "all" the fruit as it has an engine smaller than most 4cyl cars around.

Buy it and get rid of the RB20

didnt want to be the "do a search guy" but: http://www.calaisturbo.com.au/showthread.php?t=1525 knock yourself out

Rb20's don't hit boost till 5000 rpm ok that's exaduratung a bit but they are very laggy.

They're a torqueless boat anchor. My rb20 r32 copped an absolute flogging, more 2nd/3rd gear limiter drops then you can imagine, countless track days and powercruises and also street thrashing and never skipped a beat, although that was just cooler exhaust boost kind of deal, very limited power. I wouldn't do it again, but that's me.

an R32 is the same weight as a VL.. people just dont put the right diff gears (4:11s) in that the higher reving motor needs.. As AVG45 said they take a massive hiding but need to be to get anything from them.. i wouldnt touch one but they dont deserve the **** everyone is giving them.

is this guy serious rb20s dont hit boost till 5000rpm common mate mine comes on at 2800

You may as well drop in a 3.3ie becuase it has injekshun, hand grenade? yeah.

you are going to bomb out a vl anyways ruffas? drop a new drive line into the black vl..... if its a factory black calais..... get it forsure, if it isnt...... well what can i say, all your going to hear from those that know is, "looks good but its not a real black vl turbo is it?"

my old 31 was all in by 2500rpm with an rb20.. as has been said, the only reason RB20s go **** in VLs is because of the factory diff gears. Put some shorter gears in and go for gold.

they are ok with 4.1 gears but still not great. they are still lacking plenty of torque down low, you get boost then run out of power pretty quick. I dont know why people call them a higher reving engine cos with standard cams they run out of power before 6500rpm. but if you dont expect too much they are a bulletproof turbo engine.
