I asked my mechanic about porting my wastegate after I get a new exhaust and fuel pump and he said it would probably be about $500... Is this a correct ammount or does he just not know how easy it is?

 

no

 

He was probably giving you the total for Pulling the turbo, porting it and then re-installing the turbo.

even which $500 is wayyyyyy too much jake.

 

Dude you could nearly do an external gate setup for that much....

 

**** for 125 more u can get a bnr upgrade and a ported wastegate

 

It cost me about 20 dollars in porting bits and that was it.

 

Yeah he did kinda mention that he would have to take out the turbo and do all that... Still, what other way is there to do it and how much should that way cost?

 

whats book time for r&r the turbo? 3-4 hours? anther hour to pull it apart and port it, thats 4-5 hours, i dunno what his labor rate is but still for a shop to do its a $200-300 job

 

I got quoted NZ$100-120 (US$70-80) to have the flap replaced with a bigger one and the port enlarged to suit the new flap.

I don't think your mechanic understands exactly what you've asked him to do.

 

but that was you handing him the turbo? i agree $500 is high, it should be more like $250...

 

You can pull the turbo yourself, port it and slap it back on. Die Grinder and bits will probably run you $50 or so maybe a bit more. But it is much advised to weld on a new flapper for porting to be efficient on an s4 WG.

S4 WG



S5 WG


As you can see the s4 WG is really small and so is the flapper. Even if you port your WG to the max of the flapper, IMO it still isnt as good as the s5 WG, so welding on a bigger flapper will achieve better boost creep elimination.

 

I did mine for about 100.00 just because I baught a die grinder and a good carbide bit.. was easy as can be!
