Standard Series 1 Turbo Specifications

Hi guys,

It has been a while :P Life is busy...

Anyway, I need to replace the turbo on my Stag - the original is whining like a jet about to take off. Unfortunately, the cash is just not there for a serious upgrade, so I am looking to replace the turbo with something pretty stock, that will involve nothing more than bolting in and fitting up. I don't want to have to worry about wrong intake/outlet diameters etc, so can anyone tell me what the specs are that MUST be right to make this as simple as possible? And any idea what I should get? I just enjoy driving my Stag, I ain't a mechanic or a fanatic, so I really have very little idea.

TIA, and, it's good to be back, even if it is for the wrong reason...

Hey Sk0pe,

if you can't get a healthy standard used turbo (the s1 Stagea uses the s2 R33-spec turbo), then I believe the best replacement is a Garrett GT28RS, which AFAIK is a direct replacement.

Your best bet is to give a workshop a call and check with them, or speak to GCG who sell and rebuild turbos for Garrett.

Here's a few places in Sydney:

GCG Turbochargers: 1300-TURBOS (or 1300-887-267)

Unique Autosports: 9620-9000

Hills Motorsports: 9899-9962

Good luck!

T3 flange, with rb20/25 exhaust housing

Either R33 or R34 "Neo" turbo are bolt on standard turbo's

an R32 turbo would be a backwards step - small exhaust housing

scour the for sale ads for a high flow turbo

or take your shagged turbo in for a rebuild, where they bore out the intake and exhaust and use new core and new bigger steel wheels

(and compare the highflow quoted prices against the GT28RS)

search ebay, sometimes a R33/34 turbo comes up for sale
