Hi guys,

I've decided to keep my 306 turbo (no body serious wanted to buy) and was thinking of uprating the turbo.

So should i,

1 upgrade the standard turbo eg 360 bearing etc

or 2

uprade the turbo to something bigger, if so what bolt straight on without to much work.

The engine is out of the 406 sri and already has JE forged pistons,massive pace intercooler and 2 stage boost (prob why its on its way out )

Guessing Niz will have lots of ideas

Of Course I would....

In all honesty.... I'd build your own Hybrid.. that's what I've just done lol

You could go bigger turbo all over but you do want to keep it low lag, especially with the stock rev limiter no real use for bigger turbo unless this is lifted.. as for what to do, at a basic level I would recommend the following:

1) 360 degree bearing kit
2) Stagger gap oil seal
3) Dynamic Seal kit or Carbon seal kit if you want to run higher than say 18p.s.i
4) Garrett rebuild kit for wet float bearings and associated rebuild hardware

Or do what I have done...

Bored out Bearing journal / compressor cover

1) 60 Trim Compressor Wheel
2) 360 thrust bearing
3) Stagger gap oil seal
4) Garrett rebuild kit for wet float bearings and associated rebuild hardware

I've documented this process and will be including it in the KB once its finished for everyone else to use should they need to rebuild their own and save lots of money as well as learning something new

Thanks Niz, i look forward to hearing what you have done.

My next question would be how much are these parts and where is the best place to source them from?...........

Unless you fancy knocking one up for me

Hi Niz,

Im also interested in your turbo expertise for my exec.

Well Guys,

I will try and get the rebuild article done for some time next week when its back from the engineering company and I can take pictures of the finished turbo.

Will keep you updated!
