Garrett Precision Gt30 Turbo

[Tangles]

After a little advice & some knowledge from the SAU guru's.

Garrett GT30 Precision T3 turbo A/R.42 & EX.82

Compressor Housing stamped Garrett A/R.42 M24 EC-2

Compressor wheel 56trim 7-blade

4-bolt housing Exhaust wheel 11-blade,

Exhaust housing stamped Garrett 441326-016 M1 A/R 0.82

Rated to 525hp (?)

I gather I need an external wastegate, and a 4-bolt custom dump pipe 3" modifying my current JJR bellmouth dump/ront pipe

Any info about this turbo, expectations, how to mount and what sort of external wastgate to use and where to install ?

or can the rear housing be swapped out for an Internal Wastegate setup?

thoughts plx.. thanks.

this is for an auto RB25det, cams/head etc. to upgrade from Slide turbo

how much is it?

you do realise that its only oil colled not water cooled?

the 2 links you have put up are for 2 completely different creatures.

the garret web site is a 3076

while the pic link is what looks like a journal bearing high flow with a 4 bolt rear.

the cost of waste gate, manifold, and dump mods will blow the changover out considerably.

From the pics that thing is weird , I'm not so sure that Garrett actually make a plain bearing GT30 based turbo .

The turbine being 11 bladed looks different from the 10 blade petrol spec GT30UHP .

The compressor housing looks more like a T3 sized one , T04B's are mostly 0.60 A/R though they do also do 0.50 and 0.70 A/R ones as well (Garrett that is) .

It's not some kind of Chinese copy of god knows what is it ?

I'd say having a 0.4a\r front cover makes it a diesel turbo. avoid!

Get a GT3037 and you'll be fine.

Yes being big on the exhaust side compared to the compressor end makes me thing it's aimed at some sort of large capacity low reving engine - Dieseasel .

In some ways it has similar traits to a GT3071R but without ball bearings and water cooling

, diesel spec turbine .

Some sort of bitzer turbo I think . Note ID tag is not a Garrett stamped one .

Dredged up old thread .

Viewers I stumbled across what looks like a plain bearing "Garrett" GT3067S turbo thats supposed to be standard on some great stall POS bus - um 4G180-20 diseasel engine . Anyway said to be a GT30 turbocharger and the cartridge looks like a big frame non water cooled plain bearing one .

Something of interest may be the single scroll IW turbine housing with a V band outlet and what looks like a T3 flange . Nowhere I looked showed the cartridge number .

I did find pics of Garrett boxes with all the details in dead spider lingo .

The only people who may be interested I reckon are those on the hunt for a plain bearing big shaft GT30 turbine and or that T3 flanged IW GT30 turbine houing in 0.82 or possibly 0.84 AR .

out of interests sake - I ended up with a GT30 highflow from ATS Adelaide Turbo Services.
