Caught up in garrets marketing hey? The larger gtw are just a old t04z style Center sections by the looks. T04z p trim turbine..which dates back to the 70's Just a fancy t04z..950hp is absolute fairy tales for this turbo. as for latest tech..pure marketing there. Theyd use a new turbine And design a different style comp wheel if it was" latest tech" Proboost is a old p trim..with a gtx copy 67mm front wheel Those comp wheels are proven for 850hp ish.And are a new design with extended tips.. Be closer then you think id use neither. Cheers darren

Something with a turbine not trapped in the 70's GTx4088/ Pt6466-6870 /Borg warner sxe 69 be a few hybrids around the joint id try aswell Honestly Garrett can go **** themselves over selling **** covered with chocalate witht the large gtw 38 range ..what a mob of ****s.. Noticed how you dont see any reviews on them..been out a while..americans see the p trim rear and run..lots of lag there, big heavy outdated turbine, the p trim was the bread and butter turbine for them on a 6cyl ...20 yrs ago..lol cheers darren

Hi, nice car - thanks for sharing. Was this the car that sat on car sales for a while (maybe 3-4 years ago)? Cheers
