harks Posted February 24, 2015 Share Posted February 24, 2015 Has anyone ever considered getting this done? It occur's to me that a turbo option somewhere between the -9/-5 range would make ALOT of people happy. And seems like it would be a perfect match for a 2.6. I know some people will say its a waste of time and just choose from an existing turbo. But i have a set of GT-SS's where 1 needs a to be rebuilt, and currently have -5's on my car, I enjoy the -5's... but they do lack transient response and are a bit slower to get fired up. So if/when i decide to forge my engine its a perfect oppertunity to swap them out.. My thought would be turbos that could do 350kw on 98 (with all required supporting mods). On a 9:1 compression bottom end it would be a wicked street set-up. Or even with a 2.8 bottom capable of 360kw+ with full boost from say... 3200?... ballistic? thoughts?

R31Nismoid Posted March 12, 2015 Share Posted March 12, 2015 Hawkins turbos are more resembling of a -5 now than a -7. Hard to directly compare to your average joe with of-shelf items I know someone with something very similar in the pipeline currently You knew someone that had it too, long ago now though lol - Me All info here: http://www.sau.com.au/forums/topic/350440-dyno-comparo-various-twins-rb26/ Link to comment https://www.sau.com.au/forums/topic/454185-hi-flo-gt-ss-turbos/#findComment-7495664 Share on other sites More sharing options...
32GTRB Posted March 12, 2015 Share Posted March 12, 2015 (edited) I spoke to GCG yesterday asking about highflowing my -7's, he said that just results in a -5. Is that right? My understanding of watching the motivedvd vids is that the inlet size is smaller than a -5 but the comp cover is machines enough to fit the larger wheel?

harks Posted March 14, 2015 Author Share Posted March 14, 2015 That raises an interesting question... if the machining was done just to fit the -5 compressor wheel, with stock inlet diameter, would that give higher too end without -5 lag (obviously not -5 power, let's say a midpoint) OR would it be -5 lag with no real benefit because of the heavier larger moving parts with a restriction. I would think it would be the latter? Link to comment https://www.sau.com.au/forums/topic/454185-hi-flo-gt-ss-turbos/#findComment-7496460 Share on other sites More sharing options...
R31Nismoid Posted March 16, 2015 Share Posted March 16, 2015 Depends what you mean by hi-flowing... Or "making a hybrid" of the two. Similar process, different end results. Read thread I linked above and you'll see there is differences Link to comment https://www.sau.com.au/forums/topic/454185-hi-flo-gt-ss-turbos/#findComment-7497892 Share on other sites More sharing options...
