GT2510 or GT2530?!?!?

[Clint32]

gcg said they could do a t3/4 that was not ball bearing for 1800 i think, but if you just go a stock turbo you know what youve got and even if its not right you havent spent 2g

Meggala I just got a hks t04e to put on my 32, only cost 400 and I am modding the stock manifold to take the extermal gate, do you have any info on the turbo, hp rating boost efficiency range etc, thanks.

[meggala]

Dr-Drift on these forums has a vg30 turbo that was hiflowed by bill @ ats I'll get a report from him but its a big turbo.its on an rb20 now

but was on an rb25 b4

meggala

[meggala]

hey clint its a treeible turbo you don't want it .

you will have to send it straght to me

:lol:

as for info it depends on the the a/r ratios etc.

btw I wouuld love to see pic of the manifold when done

400 hp would be a good guide talk to adam32 as he has one on his r32

meggala

[Clint32]

its got a .6 ar exhaust and comp housing, not too big, about 59mm exhaust wheel i think.

the manifold is not as easy as i thought as there is not much room, i was going to do it like the jms onveia but there is less room in a 32 so the plate has to be angled to clear the strut tower. will take pics once its done wont be for a couple of months, as im dooing the inlet manifold as well and need to buy rx7 injectors and the wastegate.

[Cubes]

I wonder how the GT2530 internals would go in a vg30 housing.

Would any one know the size of the housing and any applicable other measurements/specs??!?!

Wouldn't mind comparing to the HKS GT2530/10 etc.

[meggala]

clint that turbo will be laggy it sound similar to the one gracer has on sdu and his spools from 5 k rpm just letting you know 56 mm exhaust wheel is about as big as you want to go.

ring gcg joel and talk to them seriously.

meggala

[Clint32]

not sure exact sizes but i will measure them again, just means I have to get the motor built to rev to 9grand I suppose.

[Cubes]

Stop reving when the Turbo Runs out of puff... :uh-huh:

Some serious Top End.

Good on fuel But . Coz' your hardly on boost..

[Freebaggin]

Joel,

You know Tim at RPM pretty well so why not consider the GT28 400HP unit for RRP $2300. It has a small exhaust A/R of 0.63 so spool up should be good. 4" inlet and 0.7 A/R compressor should also give you 200rwkW easy.

All you need is the spacer for both rocker cover clearence and also adaption to the T3 flange.

[Cubes]

Tim has told me about the T28 kit.

He said that it would be a little laggy, I don't know what RPM but.

I'm investigating all options, i'm also going to see what he can with a 2530.

[Clint32]

the GT28 would be very difficult to fit to the stock manifold as I dont think there is enough room because of the big compressor cover.

[Cubes]

Basically Tim can only do the T28 or the GT2510 which will only make around 180rwkw.

SO... I poped around a few places today found a HKS EVC which is a dual solanoid and has the rpm thingo and also a map sensor.

Then I came across a jap importers that is getting in a GT2540 next week that is from a GTR, he is splitting them as a friend of his wants one for his SR20.

I might put up with a bit of lag, it really depends if my injectors do end up being bigger than std. If so here I come 2540.

[Clint32]

you will still need an adapter on the manifold as it would have a t28 flange, shouldnt be to hard though, how much do they want for the turbo.

[Cubes]

Not much

ok Around the 1500k mark.

[RS500]

clint32,

fyi, the HKS T04E is actually rated at 500hp and would be perfect for an Rb20DET engine. a little laggier than the standard turbo but power/boost would come on quite hard.

check out the following link, it should give u all an indication of the hp ratings fro all the turbo's mentioned.

btw, a friend has a 400hp GT25 on his R32 RB20DET, along witha FMIC, unichip, and bigger pump and it's producing 222kw at the wheels on 18psi, with heaps more potential.

i guess it all depends on what u want from your car joel.

//RS500.

[Cubes]

So that is just a normal garret turbo no hks.

hrmm..

Basically the only thing a HKS does is be a little more efficient on higher boost levels and due to their housing design help boost spool quicker.

[Clint32]

thanks RS500, I think mine is a little smaller as it has a/r .60 compressor and a .6 exhaust housing.

[Cubes]

I can't wait to see the top end she has.

[Chris32]

Joel, what turbo did you end up getting, or are you still deciding?

Have you spoke to Ben at Tilbrooks (Brains) He has a R31 wagon with a HKS 2530 on a Rb20, been in Zoom etc. That car goes pretty hard. It makes around 220 at the wheels, but being auto with 2500rpm stall, I don't think lag is to much of a problem in that car.

I think that fact remains that any bigger than stock turbo will be a bit laggier, but the trade of is consitant boost right up to the redline

I am in the process of getting **** toghether with my car for a bit of a power-up, including turbo, bigger intercooler and maybe new injectors or pressure regulator on the existing ones.

Let me know how you go

So, just how laggy are these turbos (hks 25 series) ? as i just recieved my gt2535 today and would have thought being a BB turbo and still being reasonably sized it should be quick to spool up. I thought i should have full boost by about 3500 rpm.

My turbo has a .60 a/r compressor and a .64 exhaust housing.
