I have just bought a new manifold and now I need an external wastegate. There are 100's to choose from and prices range from £50 - £350+. I know Joe(CC) runs one but does anyone else ? Any info ones which are good and bad ?

I would probably speak to Barbz, I think he sorted it out for KTM....

First of, how much boost are you going to run, as this will decide what size you need to get

1.7 bar will be the max boost.

38mm Tial. Assuming the manifold has a 38mm pipe.

yes Tial all the way, not cheap but very high quality

Debatable about Tial. I've 2 of them, and both times they have leaked, but both fixed by tightening bolts up.

the cheap ebay ones are absolutely fine for most applications.

Tial 35/38mm gaskets are rubbish and always cause problems and leak. Easy fix is to put it on without the gasket!

or use 44mm with vband.

There'll be no harm done :-)
