What turbo for RB20?

[Psymon]

Time for a new turbo for my RB20. It's more than likely been covered many a time before but i'm new to site and in my random browsing haven't come across it yet!

I'm after something as easy as possible to fit to the car, leaving the car as drivable as possible (don't want the turbo spooling 2000rpm before redline like some other setups i have seen), and something that will leave me a fair bit of headroom for the future!

Thanks!

HKS GT2530

agreed. 2530 for abouts 280-300rwhp. excellent street turbo. no need to modify engine internals to get all the potential output from the turbo.

good luck dude

there is one thread so far... would like to have more

3/4 the way down, 200kw RB20 how to

I'll agree with the above regarding the HKS GT2530 but don't dismiss the GT2535 either !

The thing I found with the 2530 was that you smoke the tyres too much just trying to get the power down ( not really a problem for most I guess ) But when I fitted the 2535 that problem went away as the bulk of the power moved up in the rev range. I tiny bit more laggy than a 2530 and doesn't kick you in the butt like the 2530 but it does provide very smooth power all the way to the top ( even after you've done a whole bunch of mods ). Still, if you're only planning on normal bolt on mods the HKS GT2530 is prol one of the best hair dryers around for an RB20DET. By the way, it MUST BE A HKS !! Not a garrett GT2530 !! They are not the same animal.

My 2 cents

I had the 2530 and never looked back. Perfect turbo for daily driving, mountain runs, drift and even a bit of drag.

If you have a bit of bank roll get a full HKS 2835 or Trust TD06-20G setup. If funds dont stretch taht far get a HKS 2530. Thing is to buy new they are HKS2530Kai

how about a highflow rb25 turbo?

more of a budget upgrade, but should net you 200?

standard rb25 turbo will net you close to 200 highflow would give you more but I have heard that highflow can be a little laggy on a rb20. hks 2530 or 2535 would be the go.

im with roy get a trust TD06

hi-flow the RB20 turbo, not a huge difference between the RB25 turbo and the RB20 turbo, just a slight size difference in the impeller wheel (can't remember if im thinkin of the right thing or not). Anyway, there's another option, not sure if u'd get as much bang out of it though, can anyone clarify this matter?

How would a turbo from a VL perform on an RB20?

I ask as I have a GTSR with the standard fitment T03/TO4e which I think would be similar in specs to a standard VL turbo.

Yes, the technology is from the dark ages but I gather they are also cheap to pick up for the budget concious (sp).

I currently have 235+ rwkw with all support systems at 16psi which is reached at about 3900rpm.

[Psymon]

So the 2530 seems to be the way to go? i was talking to one well known workshop and they suggested a TD05 18G.

[mr_rbman]

why is the hks 2530 so much better than the garrett item and is it just the exhaust housing that is bigger on the 2535hks?

[Roy]

It probably isnt...but you have to be the one to do the homework , bolt the thing on, tune it and then see if it gets equal performance:)

Who knows it could even be a better proposition, but its just that 2530s are a known formula

[MattSR]

How well would a GT30 be suited to an RB20 with cams?

I reckon it'd be a good match if the RB20 could handle ~8500-9000 rpm or so

Cheers,

Matt

From memory, R31nismoids GT30 equipped RB25 sees about 16psi at about 4,000rpm with a tuned length exhaust manifold and all support systems.

The RB25 is 25% larger in capacity than the RB20 so in theory it would see 16psi 25% later in the rev range at approximately 5,000rpm.

So I guess, if funds allowed and you wanted to take that route a GT30 might be a decent match for a no holds barred 9,000rpm RB20.

Wheel AND Housing profiles are different between HKS and Garrett ( even though Garrett makes the parts for HKS ). HUGE difference in power delivery ( IMHO ).

As for the physical differences between the HKS 2530 & 2535, I honestly never stopped to look nor did I even ask. :bonk: It was a spur of the moment swap as both myself and the other guy wanted what the other had performance wise so we just swapped turbo's and got what we wanted :thankyou: .

[Roy]

Do you have a dyno print out of the 2535? What boost and power is it making.

[klys]

I'm supposed to have an HKS gt2535 but, on the tag it does say garett 2535 ...

and the exhaust housing doesn't look as shinny has the snail...

any info on how to identify it??

I'll take pics if I can next time
