What aftermarket turbo are you running on your RB20DET

[RS500]

I never wrote it down, but it was a Garrett tag, not sure of the number though.........When I put my new manifold on, I will take it down and post it up

MM2Death, do you have your ID number? as my turbo looks identical to that

Chris

hey chris,

fyi, as hks basically use garrett turbo parts, the id plates also say Garrett - Allied Signal.

looks will not tell u if they are the same turbo.

specs and measurements will tell u what ur turbo is.

yeah, I understand that

When the turbo comes off to put the new exhaust manifold on, I will take a few pics and measurements and write down what is on the tag

seems like 2530 type performance though

[MM2death]

I'll have a look tomorrow and write down what i can see or make out.

[Chris32]

Well, found some pics, RS500, what would you identify this turbo as?

MM2Death, does this look like yours? I am 99% sure this is what I have

Chris

The 2530 I saw looked the same apart from the tag.

The 2530 had a HKS tag. It said it was a 2540 but after an inspection from a turbo person he said it had the 2530 exhaust housing so it was essentially a 2530.

[Chris32]

Yeah, sounds about right

Hopefully RS500 can shed some light on it......

Well lifes full of disappointments.

Because we only had 45 minutes to tune my Pfc, i still dont know what sort of mumbo it has. At 8psi it made 186rwkws, so we settled on 205rwkws (at something like 11psi?) and mega conservative tune to make sure the car made it thru the thrashing it copped 12hours later at the track...

So maybe this time next week ill have a dyno printout of the car tuned...i have to say i think im going to be happy with the final result

Chris

My tag looks like that one (Garrett)

Numbers as best as i could make out...

17200-114100

UF 7042J

46701S-0021

So yeah tell me what you think...

Cheers,

Scott

[Cubes]

Same stock setup as previously Roy?

[Roy]

yep...thats a real yep too. The engine has a prob, hoping its just a lifter, not bottom end

Joel,

fyi, both the HKS GT2530 & 2540 actually have the same exhaust wheel and inturn, they run the same A/R .64 exhaust housing.

Although, on thing to note is that the 2540 was only available with a T3 flange (to suit RB20 & RB25) where the 2530 was available with both GT25 & T3 flanges.

tell that to ur turbo person and tell him that he talks :bs!:

[Cubes]

Yer I thought the 2540 and 2530 had the same exhaust a/r but he was sure the 2540 had a larger exhaust a/r.

This was Bill Keen from ATS on Marion road.

Chris,

unfortunately, i can't recognise those numbers nor can i find any reference to those as a garrett item.

sorry i can't be of any help.

don't care who he is, he doesn't know his HKS turbos.

the 2540 actually has a 'larger' T04S compressor wheel (46T - 51.7/76.2mm) as compared to the smaller T3 comp wheel (63T - 47.7/60.1mm) on the GT2530.

refer to the US HKS website which i provided for you or go to the official HKS japan website and show that to Bill Keen.

The mystery continues..................

JMS mentioned that it may be some type of Nismo turbo, but then settled for either a 2510 or 2530. Dosen't bother me, it makes plenty of power anyway for a bolt on RB20 turbo Can't wait to see what it makes with more boost

[MM2death]

Chris, it looks like you and I have very similar turbos. Those pics you attached were your turbo on your car right?

Cheers,

Scott

The pictures I have aren't digital, but are EXACTLY the same as the pics I have posted, I grabbed them of the net.

Looks like we have the same mystery turbo................seems to do a good job too We both make near identical power too, which would make me think they are the same

[CerealKiller]

hey does anyone know if a GTR turbo is a straight bolt on? I'm going for cheap upgrades, and don't really want big hp - modding for response.

Is the GTR turbo a good option or just a waste of money? (ie. will it be too laggy?)

[Chris32]

no flange is T25 not T3

anyhow, a single GTR turbo is similar to what they run on S13's etc, so no better than a stock 32 turbo

If you are after responce, why not try a R33 GTS25T turbo, they can be had pretty cheap, and would give good response and enough top end to make around 175-185rwkw, which is good power

Yep and just use the RB20 wastegate actuator for its higher boost setting.
