R33 Gtst Afm ?

[rich flavour]

hello peoples, i have a r32 turbo im my rb25 r33 gtst. i have had problems with my air flow meter so i used one off my mates he has a r32 gtst and my car flew. so i went to get a new air flow meter today and every r33 one a tryed was no good so i got a r32 gtst air flow meter now the car runs fine is my problem that i have a r32 turbo on a rb25 motor and thats why it dont like the r33 air flow meter????

thanks

Maybe you have have s2 33 afm but a s1 engine..

Man a 32 turbo on a 25 must be like the 25 turbo on my 30.. minus a bunch of torque

this will depend on what motor you have

if your car came with stock pink label AFM its series 2 and you can only use series 2 (pink afm's)

if its blue or green then its a series 1 engine and you can use r32 AFM fine (as its the same unit)

[rich flavour]

no im not using series 2 as ino there pink i have just been trying green label ones and the only one that works is the r32 gtst afm that has 4 gold pins not 5

and no the power is the same if not better coz this turbo spools up quicker lol so ur comment sucks

do you no if the blue label air flow meters have 5 gold pins for the plug or 4 like a r32 one's do.

My comment doesn't suck, I would imagine it has very SIMILAR spooling characteristics as my engine. Yes it may spool quicker but it will choke top end.

Also how do you figure that a turbo that flows LESS air will make MORE power??

Big talk for someone asking for help...

And bubba is right...power will be lower as the r32 turbo is smaller and flows less...and it will choke alot quicker than a r33 turbo...i think what you are trying to say is boost response is better...

[rich flavour]

the car dont choke in the top end it screams all the way to the rev limit but maybe i will try a r33 turbo down the track with a r33 air flow meter see what happens but thanks for guessing

hmm... i have a S1 r33 and i have a pink afm???

works great. its a 95 model (so 1.5 or whatever..) but i know the 95(1.5) model doesnt have a s2 engine.

someone has changed your afm plug to a series 2 one...for some reason

weird

weird

ino.... easy to check does your afm plug have 3 or 4 wires

can I ask how you came to the conclusion that the RB20 turbo on the RB25 motor makes the same power if not better than an RB25 motor?

and how does it not choke up top?

dyno sheets?

[bubba]

I guess ~160rwkw @ ~4600 rpm..

[rich flavour]

i never said it was better, it makes the same power and everyone has told me r32 turbo is the same as r33 i dunno if thats right or not, but this car dont choke i dont have dino sheet but what ever a stock r33 would run with a front mount on 10psi im telling you it flys past a stock r33 as i beat one the other day he did the whole turning right thing after it lol

[jake33]

yeah a 32 turbo and 33 are very different.

its hard to measure and come to a conclusion that it would be quicker than a stock 33 simply because you 'raced' one on the street.

- he might not have been giving it as much

- missed a gear

- didnt know he was racing you

- or been a real shit driver

many factors..

just out of curiosity, how come you have a 32 turbo on a 33 anyway?

[jake33]

and no the power is the same if not better

-same engine

-one has a larger turbo than the other

and you think it would be the same if not better, with the smaller turbo?

unless you have other hidden modifications that you are unaware of or its high flowed or something. i dont see how you could conclude this.

chuck it on a dyno and see what it makes i reckon

[bubba]

The turbo is going to make roughly the same power regardless of what engine it is on, larger capacity will just make the power earlier.

So, like I said, 160rwkw @ 4600rpm. Put a 33 turbo back on there and I bet you'll make ~180rwkw @ ~6000rpm.
