i want to uprate my turbo, does any one have any suggestions as to which one is best.

I assume you have a 20vt.
Well you can make a hybrid of it or buy a new one. Garrett GT28R/RS is very popular in UK. If you don't have a lot of money then go for a hybrid turbo. You don't have to change anything else, just plug it in . If you choose a GT28R/RS you need to change the downpipe (not the same exit on GT28R/RS as the original one) and some other stuff.

There's no such thing as a turbo that's "best" - it depends what you want from the car.

How much power are you aiming for?

What supporting mods do you currently have?

Do you want low down grunt or top end power? (very difficult to have both)

How much money do you have to spend?

Will you be fitting yourself or having it done by a Coupe specialist?

Beware though - once you start on the modding trail, its a VERY slippery (and expensive) slope

This is what has been done so far : has been chipped with a full stainless exhaust system and a blitz blow off valve.
I am aiming to get around 280 - 300 bhp, i will be doing the work myself,

hi guys i was going to ask the same question, i was thinking i would like power bewteen 280bhp and 350bhp, my car is standard at the moment except for a gtec1 chip, prv and boost gauge. i know it will get exspensive the more you tune, but i want to make a list of what things to get so i can prepare financially.

There is a hell of a lot of work involved with running a bigger turbo. You will need:

A front mount intercooler
a bigger fuel pump and straight voltage feed
a boost controller
a boost gauge
an uprated clutch if you are going near 300bhp
Custom mapping

What bore exhaust do you have?

Scrimp on any of the above and you are likely to end up with a big oily mess.

For 280-300 bhp I would run a GT28R or a GTI-r hybrid turbo.

i have a boost gauge and an air fuel gauge, my exhaust bore is a 2.5 or 3 inch, my clutch is on its way out so i may as well fit an uprated one, do you have any suggestions as which one to use.

hybrid-gtir, quick spooling and bolts onto standard downpipe

Well - which is it, 2.5 or 3?

For 280 bhp or so an Alfa GTA clutch will do the job - they are a straight fit.

For over 300 bhp then look at a GTA clutch with a walkers cover plate.

For 350 or so then you will need a helix paddle or helix organic - they are a fair bit more expensive.

im sure it is a 2.5 what is the differance between the hybrid gti-r and the gt28rs

GT28rs is a roller bearing turbo - will flow 340 bhp - will spin up at 3,500

GTIr is journal bearing, and will flow 280-300. It will spin up at 3,000

On a GT series turbo you really need at least a three inch downpipe to get it to work well...GTIr will work well with 2.5 inch exhaust.

hi if u had a choice what one would you choose

I'd go for the GTIR - but it really depends on what you want from the car...see Nigel's post earlier in this thread.

The superspool is another nice option, I'm getting 300bhp with one fitted.

no mate.
cheers i have read it and it is a lot of help i have the idea of the route im going to take

what sort of power can you achieve with a standard turbo?

About 250-260 bhp as an absolute maximum - most cars produce around 240bhp.

As little as that? Sounds like I need to go for a hybrid (GTI-R?)was hoping to go for 280-290 ish where would be the best place to go for one?
