Hi all
iv'e voted with my feet and chequebook and had my turbo upgraded to the gcg b/b gt30/71 hi flow option.
Marty wasley from "mw performance" on the sunshine coast did the removal /refit. He confirms that it is a"cop of a job"However, the refit was made easier with the 3" dumppipe (supplied by Angus(Andrew) thanks mate great bit of work),this dump left more room around it for for fitting.This pipe was connected by front pipe with mandrel bends (then small flexi pipe ,with 200cfm? hi flow metal cat.This was joined to the fujitsubo legalis cat back exhaust to make a very sweet sounding exhaust.
As far as performance is concerned . It now gives a genuine push in the back when fired up in anger.The lag factor in my opinion is actually less than it was originally.It comes on boost about 2300 rpm and then just climbs rapidly.
Perhaps most of this comes with the hi flow exhaust which works and sounds a treat. hope this encourages any one doubting the hi flow gcg option.(I say this knowing others will be after more power but for the moment this will be enough for me)..
