I'm after the answer to wether it's possible to run an external wastegate on a VF35? also if so is there any bonus to do this? I would imagine better boost control would be the first thing.
Thanks for any input.

alot of expense and hassle for a vf35 mate, are you getting boost creep/surge.

porting the wastegate is a good mod see someone like harvey( he`s not well atm)

 

Best thing to do is get the internal wastegate ported , this solved my boost creep / Boost control problems.

External wastegate is not needed imo

 

The car isn't running yet but I just like to make thing as good as they can be. If there is no difference between a well ported internal wastegate and an external then I'd stick with the internal however if an external will maintain better boost control then I'd rather cough up now than be disappointed down the line.
Cheers Ian.

 

If done right it will work fine, sometimes you need to get a stronger actuator aswell.

I did my old Vf35 and my current turbo the VF48 , using a air grinder. Once you have removed enough material its just a case of getting a smooth finish on the metal

 

Did you split the turbo to do that work? if so do they come apart easy enough? would i need to replace parts if i took it apart?
Cheers Ian.

 

Yes you need to remove the turbo from the car, then the clamp securing the exhaust housing to the core , depending on the age of the turbo you may need to pry it off, be careful not to damage the turbine blades.

To refit there in a locating pin in the core so you know the orientation/alignment of the housing is in the right place on the core.no parts are needed.

I did this myself because no body does it here in Ireland that I'm aware of and I wasnt in a position to pay to get it sent over to the Uk for the job
