Don't get a new turbo till you change that 2.5" exhaust for a 3" one, otherwise the turbo you get won't make bugger all of a difference, all you'll be doing is restricting the crap out of it with the exhaust you have.

And while you're getting that new exhaust, and while you want that much power of that RB20, you'd better get one with a split dump pipe

Do a search mate...everything you want to know will be answered...its been covered heaps of times...first things first...you have to decide how much power you're aiming for...and then go from there...have a look at the rb20 thread in the sticky section...you should be able to get a good idea from there...

the sticky thread has suggestions on all upgrades for an rb20det.

if you read through you'll see results on various turbos.

people who have actually experienced the different ones have given comment. i personally have used a rb25 turbo for a cheap/mild upgrade and also a hksGT2530.

just have a read and try to sift through the bullshit and decide what you think is the result you're after and start sourcing one.

sounds like you have a good base (apart from that exhaust) and a few more mods to come then just a turbo selection and a tune. have fun.

i actually just checked my exhaust i think it might be 3 inch it looks big and its loud i measured it and its probably just under 3 inch from the outer material im not sure how thick the metal is

how do they measure exhaust size is it from inside diameter or outside?

i might have to ask someone who knows go past an exahust place or something

do you really think it would make a big difference with a 2.5 exhaust?

Most people go with a HKS 2530 (200 - 230 RWKW)

You could get GCG to hi flow your stock turbo that will set you back about $2000 and give you a bit more power then the 2530, I have a hi flow waiting to go on I just need money haha.

but yeah rb20s dont put on much of a show off boost so be very careful not to get something too big, had a t04e on mine for a while, was good once u were boost about 4900 5000 real good, but sucked until then no fun on the street.

Yeh as some one said b4 the 2530 unless you can affrd to hi flow a rb25 turbo (non hi flowed rb25 turbo probably wont see you through to 200+) or maybe a vg30 if you dont mind some lag (some one selling hi flowed examples for fairly cheap on these forums)

Yeah im so unsure i want about 230rwkw

but i want it to be quick off the line and not too much lag

the standard turbo isnt too bad for lag but no real power

im thinking ball bearing turbo but dont know what

it has to be fun on the street too

Get a 2nd hand 2510 then...or get a 320-350hp turbo Garret turbo. Better aerodynamics, still bb and you can wind some decent boost into it unlike with an R33 turbo.

If tuned well the RB20 is pretty happy at 1.2 bar, so it seems a shame to go to the expense of getting a new turbo on the car. New gaskets, chnage coolant/oil etc, get the thng tuned accordingly only to be limited to about 1 bar.

With a small steel wheel turbo you can keep the response but boost it on up and get reasonable power.

Can anyone put up a plot of an R33 turbo on an RB20 which has been tuned for fuel and ignition?

I am in the same boat RB20det with standard turbo.

I have had an RB20 with an RB25 turbo before and it is a good thing but 180 to 195 is the best you can get out of them.

If you want 210 to 230 a 2530 is the go.

I have found it really hard to find one and am now looking at other options.

Is there a Disco Potato available for the RB20 in the same pattern?

If not I will be going a hiflow like every man and his dog. because it will bolt straight on and look stock.

Are there any other turbos that are suited to the 20 other than

2510, 2530, td06 20g?

    • They see me rollin' they hatin'....... Took me most of the day to make the necessary mods to the mounts to make them fit the car.  Fortunately I was able to just use the mounts that came with the rotisserie. The rear ones are really secure, the front I feel i might reinforce a bit more as it doesn't seem like enough attachment to the vehicle. I'm sure it's fine but better to be safe than (extremely...) sorry.  I drilled and tapped thread into additional M12 holes to each car mount where it attaches to the rotisserie as an extra fail-safe. Without them the side to side movement is just restricted by the allen head pinch bolts, nothing actually goes though the beam. Does now! I still need to adjust the rotisserie to get the car centred in terms of centre of gravity. If it's too high or too low relative to the rotational centre line of the car, it will be like a turtle and roll onto its back or as it currently sits, I dont think I'd be able to rotate it as it sits as it needs to lift the whole car up as it rotates. Ain't happening... I'm going to be nervous as hell the first time I go to spin it on its side...    
    • Oh yes done this when the window started flopping around.  Turns out the guides that run along the rail chanel had crumbed way. Took off the door card and pulled out the window mech, then the window, which you have to pull out through the top. As said unbolt the guide rail and don't spend 30 minutes getting frustrated trying to find a way to slide it out upwards cause that don't frigging work. Drop it down and out through the door hole. All I did to repair it was slice some 10mm clear plastic tube, vertically, then screw it to the guide rail both sides. This tubing rolls inward on both sides and leaves a gap wide enough to hold the window. To finish all I did was lube the plastic tube with olive oil and Bob's your uncle . . . well if he has the operation he can be your Aunt ! !  10 bucks in plastic tube and another 5 minute job done again . . . . YEH BULLSH#T ! My love for Skylines knows no bounds !
    • So was there a solution to this problem? I’m having this issue now. 
    • not expensive, just irreplaceable if you don't go sub 60 at wakie in that thing people will start talking
    • I haven't replaced that, but I have had the doors apart on the r32 a couple of times The door skin will be held on by a combination of clips and bolts, just take it slowly and make sure all the sneaky hidden bolts are out Once the skin is off you should be able to pop that piece off pretty easily, looks like there are only 2 bolts holding it on
