Hey guys..

Whats a decent turbo to suite rb20 that can provide around 230-240 at the wheels with minimal lag?

I currently have a GT3071r but find its a bit laggy for daily driving.. doesnt come on till 3500rpm.. im looking for something that comes on around 3000 if not earlier and still pulls through the whole gear range..

anyone got an suggestions or ideas? and if you have one has something they wana get rid of.. let me no. I'm also interested in swapping mine for something a bit smaller.. suites rb20/25 manifold direct bolt on.

also.. is there even much difference between HKS and garrett? or just a massive price difference!! lol..

cheers

Paul i have a standard R33 turbo and willing to do a swap plus $$ your way for that GT3071R mate....you could try the R33 turbo and see if that makes a difference....mine on 12 psi made 211 on a RB25 though....i have heard of my mates r32 making 190-200 with a few supporting mods and a R33 or R34 turbo....and apparently its very responsive

Im currenttly building my own turbocharger, should be the sort of thing you'd be after.

ie a garrett GT2871R instead of your gt3071r

Ive got a garrett gt2871r chra core, pulled it down and she's cactus.

purchased a new centre ball bearing cartridge, purchasing a garrett exhaust turbine shaft with 60-1 front compressor wheel and full rebuild kit

using my hiflowed and ported rb25 compressor and exhaust housings

all up $500 cost plus a rebalance fee at ATS or MTQ, less sale of current highflow chra

;) ba boom ! now theres how to save a grand on a turbo :(

mate i got a 25/30 making 17psi at 4300 and that is one of the more responsive turbos u can get for a 20 that makes awesome power

u gotta go for a 25 if ya want power

if not go high mount external and u'll get full boost at 4000 give or take

+1 2530!

There is a whole SAU forum dedicated to this sort of question with hundreds of different answer and opinions. Did you even do a search for "RB20 turbo" or something similar?

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
