What Turbo To Get For My Rb20det

[Italiazr1]

Ok guys here's a project for you's

I have an r32 gts-t 1990

already running

2.5 turbo back exhaust high flow cat

nice size fmic

greddy profec ebc

cheap pod filter

about to install:

low mount manifold 43mm hole 3mm thick stainless steel

660cc gtr injectors

wolf 3d version 4 ecu

fuel pump

only thing left to buy is my turbo

now i dont know a dam thing about turbo chargers

exept that bigger give more lag but more power

smaller hit boost quicker but not as much power

i want my car to be fairly quick im hopeing to get about 230rwkw but maybe one day get a bit more lets say 260rwkw to be conservative

i need to know what turbo's are good whats bad about each one ect

can anyone help?

i would like to run maybe a high 13 sec quater do you think i will get this with my set up?

any help appreciated

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

[Italiazr1]

ok well once ive done that what turbo should i get?

[WazR32GTSt]

rb25 turbo. do a search

[limpus]

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...

[Italiazr1]

ok thanks do i just search for (turbo's)?

[rb20inside]

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?

[barnoon]

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.

[Italiazr1]

what are you running in yours other than turbo

[WazR32GTSt]

most people don't go with a 2530..

most stick with the stock turbo or go with an rb25 turbo

reason?

trying to minimise the lack of low down torque

[The Dan]

Post the following:

Maximum boost you wish to run

Total power you wish to achieve

RPM when you want maximum boost

Maximum RPM you will be using.

[AlexCim]

id go rb25 turbo

[ODessA]

have a good close look at a gcg highflow (rb25), they are really awesome turbos ive got one on my rb20 its fantastic .

[ODessA]

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.

[GTAAAH]

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)

2510 - similar lag to R33 turbo, with the ability to run big boost = more torque

[Italiazr1]

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?

[CEF11E]

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?
