[Mk2] [Turbo] No power on boost

[Matt49a]

My rev 3 tubby is not boosting properly

It goes up to 3k/4k and then lags it feels like there's no turbo

I have checked all the boost pipes and they seem ok

any help would be great

[markstevieandmads]

pop the turbo hose off and see if the turbo turbine feels ok.

[Matt49a]

just been and checked and there's play

can I rebuild it myself or is it better get a company to do it

Sounds more likely to be a different problem unless the turbo is properly fubarred. No boost at all?

[Matt49a]

There is still boost there it just lags and pops and splutters from about 3/4k

How old is your ignition?

Have you checked for codes?

We have replament CT26 turbos in stock if you need one or can rebuild CT20B

[Matt49a]

Ive got no fault codes

Its a ct20b, what price would a rebuild be on it and what kind of turnaround time

Thanks

I would need to see it to see how bad it is, but if it was just bearings and seals I would say around £300 to £350.

Time would be about a week or just over depending on the parts needed.

Boost lag and popping/sputtering doesn't come from worn bearings or seals. Check your ignition components and your static timing first.

Sounds more like ignition, fuel or vacuum issue
