Garrett GT30R turbo upgrade?

[oor33sky_]

What other mods have you got? What engine management are you using?

injectors, fuel pump, external wastegate, fmic, 3" zorst, elec boost @ 15psi

running GReddy e-manage

proper tune with g/box sorted should net 350-400rwhp

How's it goin Disco Potatoe lol. Is this the turbo you are talking about???? This is the one I might be buying, on the left.

Yes  to the port shrouded .60 AR covered six blade unit . This turbo's (GT30R) part no is  700382-12 and is sold without turbine housing . 704902-1 and -2 are the part no's for 1.06 and .82 AR exhaust housings . DO NOT FIT BORED OUT T3 or T04 exhaust housings as the nozzle section is different and does not work properly with the GT type turbine .

just as an idea for u JB i have a t04e with .60 comp housing and 1.06 rear starts boosting at 1600 on std rb25det. gets a bar around 3500rpm

Hey Kamikaze,

thats nice early boost. What is the power output? any other mods done? How does the t04e hit? nice and hard? :aroused:

i just ordered a gt30r from cheapturbo.com it is the 'right' gt30r with the 6 blade wheel and shrouded inlet.

its gonna be going onto a rb20 so i got the .63 ar turbine to help it get going.

i think with cams and the hks exhaust manifold i have it should do pretty well for what im looking at.

1 bar at 3500 is not bad at all, if i can get that on my rb20 i will be more than happy, seeing as i plan on running low boost around town (10psi) while high boost will be in the 17psi range.

RB180SX that looks like the one . If you do a search on HKS USA it gives the trims and inducer/exducer diameters .

[discopotato03]

RB180SX , just been back to the HKS USA site the compressor inducer should be 57mm for a 56 trim comp wheel . The turbine exducer diameter should be 55mm . If you look at the HKS GT3037 Pro S version they mention two T3 flanged integrally gated exhaust housings in .68 and .87AR . The exhaust outlet is called GT Pro and if anyone has pics of it I'd like to see them . Its pretty obvious the .68 is aimed at RB20DET's and the .87 at RB25DET's .

Brett Lloyd of GCG Turbos (Condell Park Syd) sells some HKS Turbine housings seperatly and may have these as well . If they can be obtained either of them on the back of a GT30R should make an easy convienent conversion on a single turbo RB six , always assuming the compressor cover cleared everything and same with the waste gate actuator . Not having seen the GT Pro outlet I'm not sure what elbow pattern it uses . HKS sometimes makes these things vehicle specific so it may be like the RB20/25 outlet .

So many choises , cheers A .

Bush bearing old school turbo with 1.06 rear making boost from 1600rpm on a stock rb25??? I wouldnt put money on that

Can you get the gt30r with a flange to fit the stock exhaust manifold? The reason i ask is i have a high mount manifold with the stock turbo flange, i wanted to use this to mount the gt30r there and tap in a wastegate pipe.

Also, when i get this turbo what size wastegate should i use? Max boost would probly be about 16 psi.. I want to use the .68 exhaust housing to try bring boost on a little quicker if that makes any difference.

Cheers

Which exhaust AR would be better... 0.82 or 1.06? 1.06 might be a bit laggy right? although I will be looking to change the cams at the same time so with tuning that might help a bit.

dont get the 0.68 rear housing as it will bring on power 2 early in the rpm and just causing wheel spin.

Go for a 0.82 or 0.86 rear housing.
