audi tt petrol turbo on a diesel

[GTIcheeseman]

Right my mate has got a pd 150 and he has put an audi tt petrol turbo on it, now when I was studying I always got told you should not do that as petrols run to much higher psi than diesels ,
Is that right

[cullygti]

i always thought a diesel runs more compression than a petrol

[GTIcheeseman]

Yeah engine wise they do but I always thought you shouldn't put a petty turbo on a diesel. I know diesel engines run a lot higher engine compression

[cullygti]

dont quote me on this but im sure the actuator on a diesel turbo is setup different to that on a petrol turbo how i dont know as cant remember exactly but remember reading summat about it on here

How does that work??  The diesel has variable vane turbos.........

[Wazzzer]

does it run?

[Nino]

Very interesting.

diesels boost way higher than petrols, particularly in standard form. I really can't see how your mate has managed to achieve this.. it just wouldn't work for so many reasons. Unless he's used a turbo from a new shape diesel TT? but even that wouldn't be straight forward!

[golf-sib]

Diesels are on boost much more under general driving conditions

Diesel one works on a vacuum...I assume the petrol one is the other way around.

does it run?
