You will hate anything bigger than a 61mm if going from the small perky FG. Link to comment Share on other sites More sharing options...

xr6t_ute Donating Members 2,281 Member For: 17y 8m 13d Gender: Male Location: south east suburbs Posted 26/02/12 11:03 AM Share Posted 26/02/12 11:03 AM (edited) You will definately need a retune, 98% of cases that you change on your car(performance wise) will need a retune. If you dont there will be consequences and can be expensive ones of that.There is more flow on the billet wheel, its a simple retune and shouldnt cost much if you went back to your tuner for a touch up.

nelsonian101 Donating Members 961 Member For: 16y 8m 13d Gender: Male Location: Sydney Posted 02/03/12 09:34 PM Author Share Posted 02/03/12 09:34 PM Well had the turbo serviced at GCG in Sydney and can highly recommend their prompt service.The usual turn around is 4 days but they had it done in 24hrs (as I had the car waiting at a suspension place getting a front camber kit made), looking all shiney and brand new sealed in plastic in a padded box. Unwrapping it was like Xmas all over again!After a full disassembly it was found the bearing pack cages were broken (possibly due to the high oil temps at the circuit before I put my engine oil cooler on).The back plate had a step worn in the seal ring area causing excessive play. All the piston rings and seals were worn.The turbo was fully carbonized cleaned and all new factory service kit components replaced. It looked brand new.The bearing pack was fitted with an upgraded steel bearing pack cage. The turbo was then fully balanced on machine.Expensive. Approx $1,100 but this what what I was expecting. A brand new F6 turbo would cost $2k minimum plus the $500 re- tune, so I save $1,500 approx.Excellent spool up of the stock FGXR6T turbo is retained with strengthened reliability too. 1 Link to comment Share on other sites More sharing options...
