Just a quick point, if you are goin to undertake this conversion, do yourself a favour and put in a selt of 4.11 diff gears it makes it 100% better to drive than the 3.45, also I have just previously ran a 9.808 over the 1/8th mile in mine, with a stock engine with a fmic, 3" exhaust and 14psi boost

RIX-PSI - To get 200RWKW, best idea is to get a HKS GT2530, highmount and a Apexi PowerFC, this is what I will be getting later this year and from what i have read is good for 230- 240 RWKW

got no problems wit the rb20's but, i wouldnt consider it a VL without the RB30, and if your looking for 1/4 mile times to be honest ive hardly seen any vl's with rb20's running challanging times for the rb30's then again i might be looking in all the wrong places!

the Nisssan Rb20 (except the single cammers we sent to NZ) is the most tuneable motor out.Yes 2.0l, but that means revvy which means boost. The vl is a lighter body than the R32, and acctually has a bigger "parts bin" ranging from the VB Commy to VR and also R31/2/3/4 and some other GM and BMW cars.
It is similar in design to the RB26DETT and RB30 series 2 blocks. but like the holden 253 compared to 308/304 blocks, has thicker bore walls. The head is some what the same but dont remove too much metal, the ports on the rb20det are straight just open em a bit.

Rb25 is the way to go, Rip out the old Rb30 single cam 16 valve crap,
give it a bit of JAP power not some rebuilt holden 95kw at the wheels crap
wtf are you talking about? Are you saying to go the RB25 cos its got a twin cam?
Btw rb30 engines have 12 valves
Also they are a nissan engine, not a 95 kw holden motor

this what i beleive that the rb20 can have very quick exceleration when set up right as the mods listed above. but like every engine theres only so much you can get out of it which i don`t think anyone on here has that much money to get it to the point where we can`t get anything more from there engine. best way to get power is the good old power to weight ratio but then there is the cheapest way to get power.

so assuming evey one wants most power for least money rb30 would be cheapest but if our looking for huge power 25 have more pottential.

Juice comes in 3l now too. Actually I've seen juice and water in varying sizes from 300ml up to 5 litres or so. Pretty sure you can get a 3l milk too.

No way, RB26's are crap. Only designed for econo shi tboxes. Better off putting in something like a starfire four.

OK i have read all the posts and i agree the views of some people are some what DISTORTED. everyone has there own ideas and view on the subject but it all come down to personal experience or mechanical experience.

Japan has been doing it better for ages
In japan in 1989 there was a race series like our clipsal 500 or grand prix where a bunch of turbos were raced and then they released the r32 gtr (godzilla) and it (that type of car) won 17 out of 18 races the it was raced in and because of this the japs abolished the series. The japs also provided all you's with what you call a turbo through there designing and engineering.
you look at them and say that they ar still making inline sixes and the fact of the matter is that an inline six is still making the passes down the qtr mile (in the turbo class) that are top of their class. even in the new r34 they put an inline six in it.

Now we will start with the rb26DETT.
A.K.A. GODZILLA MOTOR
The rb26 is a 2.6 litre motor that has a twin cam head ( now those few words - twin cam is like getting 50% extra free on you 1 litre milk). twin cam heads flow more than singles so much more that when it comes down to it your going to have more middle range power rather than 2500-3000rpm to 5000-5500rpm on manual vlt.when i say more middle range power i mean between 4000 and 8000 rpm. The rb26 can also be bored out to 2.8 litre (almost a 3.0 litre). it offers 2 turbos of one rather large one (T88D).
Japan's transport authority\or standards commisson(what ever our aust standards is to them) is also like ours where they put down a limit to how much power cars can come out with from factory. This is the case so much that with just a few minior mods to the rb26 engine you can come up with comsiderable gains of upto 50rwkw (using an exaust and removing boost valve stopper and tuning ecu). and the engine does not have very many limits i have heard of high power gtr's all the time

Quote:
if the cars power plant is it's engine, then put a rb26 in a vl and crank that power
now for the rb25det
2.5litre twin cam ( <- there it is again) single turbo
the rb25 offers an extra half a litre over it younger brother (rb20).
it was made for the r33 skyline and has a small amount extra of power but not that much. A rb25 stock motor will not handle as much power as a rb20. These engines have also been detuned to meet regulations.
but at the end of the day if you put a rb25 and a rb20 side by side and spent $3000 - $4000 on them the rb25 would onlu give you a max of 50 extra rwkw.

the rb20det
2.0litre twin cam (<- there it is again, the japs must be on to something) single turbo
the rb20 is a almost bullet proof engine allowing the internals to cope with upto 400kw of raw power through bolt on parts before the internals have to be changed or modified. They are also detuned and waiting for an exhaust to be bolted on.and from experience of being beaten in my vlct rb20 conversions are good if there done right and the engine has the right bolt ons

In posting this i hope it helps in resolving some issues
