My Turbo Rebuild Update
My T34 has been sent off for a rebuild and just had a call notifying me of the list of problems with it 
Excessing scoring on the blades
Penny valve fooked and bent
360 bearing fooked.
slight crack in 0.63 housing
and a few other bits which i forgot to write down
the guy rebuilding it even says to my mate the car must be running some high power for it to damage it like that
erm yep @ 400 bhp and getting thrashed around Silverstone twice does tend to take alot out of a turbo
I was expecting a repair bill of 250 but have bene told its gonna cost 450 for the all singing all dancing turbo properly built.
Now I wish o bought that GT35 on ebay the other week for 500 quid
Still at least the car will be on the road by the start of June
even if t is only for a few weeks until my insurance runs out - then its decide to keep, sell or break

Ran, please remember a change in turbo will require additional mapping to compensate for the big blower.
So too all that cost add in a additional £250 - 400 for mapping

Jay that is true if you are changing spec of the turbo or any other component within the engine.
Im not tho as my turbo is being rebuilt but will have a few nikasil coated items (i think to stop them bending) so in theory its pretty much the same turbo but newer.
I will obviously get it checked for Det. Am also on the rollers with the Berks crew so will be able to tell when its on the rollers.

apparently, the cause of the penny in my exh housing being bent and skewed up was down to the actuator being wound too tight. Neither Geoff (My mechanic) nor me have touched this since the car was setup by Mark @ Grove and Ahmed last year.
I find this quite hard to believe that they would miss this or even do it but im not gonna point the blame as it was a year ago.
