Actually works out cheaper. Above price works out to $340. So at 190 & 110 I wouldn't be complaining.

Read the post mate. $165 for porting AND flapper. $165 for the actuator so $330 all up.

My quote was with no actuator so add $165 to my quote and you get $465. $165 for porting and flapper compared to $300 for porting and flapper. Would you be concerned?

that's still cheaper then I paid at autotech down here in sydney. I paid $500 and that was just to giving them the turbo. I would not be complaining!!!

My quote is for giving them the rear housing only. I've also removed the flapper and arm from housing!!! Look at the difference in quotes mate, only 4 months apart and from the same company! Seems as though I should just shut up and pay the extra $135 for the same job?? :beerchug:

Don't know about other places but when MR Turbo ports the wastegate it’s not just to make the hole bigger.

If you get only your wastegate ported what happens is your standard flapper is retained and the hole is bored out to its maximum so it still seals, then the inside of the housing is ported and the angle the exhaust gasses come to the flap are changed / improved and polished.

If you only go to the bigger 38'5mm flapper what happens is the standard flapper is removed. 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.

I got a quote from the same place today for porting $190 and larger flapper is $110. WTF!!

maybe he quoted u for porting of the actual ex housing, not just enlarging the wastegate ?
