In have a 38mm external and its a touch to small and it will end up a lot more expensive.Simon did some 42mm internal ports a while back. Not sure if that's the path he still goes down. He will obviously retune it so $1000 is reasonable. Best just to book it in and get it done :-) Link to comment Share on other sites More sharing options...

My turbo is 90 thousand old now and still holding boost OK even with new crow springs retune and a few more wasps. Gearbox is really next on the cards for me anyway so I hope the actuator holds out a while longer. When it does go south I will probably go another stock spec one as I'm happy with power levels to be honest.Once you get it sorted Matt, have a gander in WA section and come for a cruise! Watch out for the cruise controllers though they are d!ck heads and some even get punched in the face hahaha.

-LYNCHO- Member 16 Member For: 11y 8m 4d Gender: Male Location: Perth Posted 02/03/13 01:42 PM Author Share Posted 02/03/13 01:42 PM Mine has done 108,000 so would it be better to just buy a new turbo? Perhaps one with a flapper that's large enough already? Not wanting to go for a high mount just yet either. The car however rarely gets driven as I work away and have a second car, and does not get driven very hard so maybe I can expect a little more life out of the turbo? Or have it rebuilt???

Make sure you bring all 51kw of the Brumby! hahaha. I post a new thread in WA section when the cruise is being organised, probably 2 to 3 weeks from now.

I've got two other mates with turbo falcons who are keen to jump onboard also.Think I'll be leaving the brumby in the shed for that one mate, don't want to be showing up the boys in their Ls1's aha Link to comment Share on other sites More sharing options...

Since my turbo is old, whats the max rwkw I can push on the fg xr6t without getting the flapper mod done? 280rwkwish would be nice Edited 04/03/13 03:53 AM by sct911 Link to comment Share on other sites More sharing options...
