Buick GN Turbo Exhaust Elbow Porting

Intercooled or Hotair - $75 + $10 Shpg

Includes bead blasting and porting work on your elbow

   Let Us Do Your 

Dirty Work!

Even stock turbo GNs are losing HP and Turbo Spool Up Speed if using the stock exh. elbow. Some tweaks here will pay dividends at the track or on the street and you can save that $450 3" downpipe expense until your car is in the 11s. It won't gain you anything more than a ported elbow will if you can't run 115 mph in the 1/4 mile. 

So, send us your elbow and we'll clean & beadblast it then do our tricks to help you pick up that extra tenth & 1 mph. It's a good bang for the buck! 

Turbo Porting does not include any disassembly. Please ask about rates.
