Get your turbo taken off the car and send it to them. Its your best option. 1 Link to comment Share on other sites More sharing options...

The exhaust housing is put in a mill. A new flapper seat is machined into the housing because the standard seat is not bigger enough for the big flap. The hole is bored out and the new 38.5mm flapper is installed. The hole is bored to suit the bigger flap but the housing is not ported.MR Turbo quote both of these things as separate.They also sell the 38.5mm flap valves by them self for other mechanics and exhaust shops to fit them.If you wanted to get it all done and installed you would have to give them the turbo and ask for: The Big wastegate flap, Porting and new wastegate actuator / can.Three separate things.What one person calls porting is not the same as the next guy. The pictures I have seen on this site have been of the hole been bored but not ported.They only work on turbos not cars so the turbo would have to be take off and given to them.whats it worth to get all 3 items done?

I know a few guys who have used a die grinder and it workscheers, J Link to comment Share on other sites More sharing options...

Flapper I used was 38mm and I tried to machine a new seating surface with a 42mm bit but it wouldnt cut??? I ended up using a die grinder keeping the standard seating surface and then cleaned it up with a small poly-fan. You need to leave the bottom of it flat so the larger flapper doesnt catch. Probably could have got the right bit to machine it but I was in a rush to get it done so I could get my tune. It came up a treat. I have no boost spike and it holds a flat line on my dyno sheet at 15psi right up to redline. Edited 18/07/09 02:49 PM by FPV_Steve Link to comment Share on other sites More sharing options...
