Turbos For Rb20

[jonohr32]

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

you want that much power with no lag

good luck coz you may as well get a bigger motor then youll have less lag and more power

[jonohr32]

id be happy with 225-230..

well if i could find someone selling rb25+ motor and gearbox id do that instead but to hard to find.

[jonohr32]

anyone got any suggestions..?

even if it can make a nice 225rwkw and just not be laggy ill be happy..

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

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

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?

i did a search but it didnt answer my question.

Surely there is some sort of smaller Garret that can be at full boost by 3500 and still provide 230kw's?

[rad100]

buy my apexi! made 220 @ 4000rpm @18psi!

[jonohr32]

my gt30 makes 15psi by 3800 and that makes 230.. im really looking for something i can have full boost by 3300.. 3500 at the LATEST .. 225kw i would even be happy with.

[nos man]

get adjustable cam gears?

[Damo_R34]

if you want good response, twin charge it or highflow your rb20 turbo

[rad100]

are you joking? u wanna make MORE power and REDUCE lag...

hahahahhahahahahahahhahahaha......

your rb20 is RESPONSIVE compared to alot of others..

save your $$$ and buy a 25 and strap the 3071r on it!

[jonohr32]

like i said i want to sacrafice the power i can make with the gt30 and start making less power but more lower down.. is there any mods u can do that will minimize the lag with the gt30?

[jonohr32]

[Dori-Dori]

cams and cam gears?

+1

to that

but seriously

more power less lag AINT GONNA HAPPEN

wen will you listen

For 200rwkw+ RB20's dont get up and go until 4000rpm minimum.

They can start making a 'little' boost before but 4000rpm+ is it for the rb20.
