Re: [Mk2] [Turbo] Turbo Options
I've got a downpipe for a ct26 where it isnt welded in, any use?

Re: [Mk2] [Turbo] Turbo Options
bit of a thread revival as I have a query along similar lines.
Got my turbo apart
(exhaust/compressor housing removed) to rotate the compressor housing slightly and apart from needing a good clean there is some slight radial movement in the shaft but from what i've read that is to be expected with no oil pressure in the bearings?
![](./images/smilies/spacer.gif)
In terms of rebuilding i've read upgrading to a billet compressor wheel and replacing the ceramic turbine wheel is recommended as they self destruct? Came across these on ebay![](./images/smilies/spacer.gif)

never heard of Kinugawa myself but again reading on forums some people say they are half decent
(not Chinese made).![](./images/smilies/spacer.gif)

Re: [Mk2] [Turbo] Turbo Options
Correct
- quality is top notch.
I'm rebuilding my CT20B right now and using the following components:
![](./images/smilies/spacer.gif)
Kinugawa inconel turbine
(Same as you've listed)
Mamba Billet CT20b With Extended tip
(The wheel you've listed is not extended tip)
Melette CT20b
(CT26 small) rebuild kit.![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
Note
- I'm getting it professionally VSR balanced locally.
The turbine and compressor wheel are supposed to be balanced individually.
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
I'm also going to port the wastegate holes and turbine post turbine wheel to help increase flow somewhat.
Hoping for a 30rwhp bump similar to what the US guys are achieving.![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
Can anyone recommend which is the better route to go when porting the housing post turbine.
stepped lip, or a tapered tip?

I sold it to sheppy, he then sold it to another member, maybe worth tracking the buyer down because they may not have used it, would be a cracking purchase for you.
clutch was slipping unfortunately, but you get the idea![]()

Re: [Mk2] [Turbo] Turbo Options
2mad, I see you ported the compressor outlet as well much noticeable difference? although I guess it was probably hard to judge since you ported it all at once?

Anyhow, followup from my earlier post I bought that steel turbine wheel/shaft, billet compressor wheel and rebuild kit.![](./images/smilies/spacer.gif)

Re: [Mk2] [Turbo] Turbo Options
Yes
- thats the wheel I got.
Please check it fits on the new shaft.
I found mine was out by the smallest margin which meant getting it bored out and re-balanced as an unforseen cost.
Error was on the wheel, as I measured the shaft
(Old and new) and they were in perfect measurement.![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
I got my bearings from turborebuild.co.uk which supplied me with Melett parts.
I could have easily re-used the old stuff as it was like new still.![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
Only just got it on the car but haven't had the opportunity to really test it out.
Still having to mess with the EBC to get boost where I want
(17psi).![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
Spool feels pretty identical to the ceramic turbine, even though I'm now on the steel one which is good news.
I would say the top end does feel faster than the old wheel so far when running 15-16psi in 2nd gear.

There is the version that comes from the gen 4 3sgte that already has the manifold as part of the turbine housing.
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
Only thing is the exhaust side has a different stud patern so needs a gen 4 downpipe or custom.
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
Apprently they spool earlier but they can't do as much at the top.
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
If it's only spool times and not top end you are after, it might be an option.
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
![](./images/smilies/spacer.gif)
Also you'd need a manifold to use another turbo afterwards, so more cost.

Got one going in with my gen 4 setup but will only be running about 300 crank hp.
