Garrett GTW Application Notes:
NOT a direct drop-in replacement to the small frame Garrett GT or GTX Series turbochargers
External dimensions of the GTW Series bearing housing (CHRA) is physically larger (bulkier) than the Garrett GT and GTX series
DOES NOT use same oil feed and oil return fittings as the small frame Garrett GT or GTX Series turbochargers
Why are Garrett’s GTW turbochargers a much better comparison to Precision’s units than they were before the GTW? Well they are much more budget friendly, because the CHRA is completely different. It’s larger and has eliminated its water-cooling ability. This line of turbocharger is an oil only CHRA, something the GT series ball bearing line up never offered before. What this suggests is that people were trying to do a direct comparison between Garrett’s GT line up and Precision Turbo’s line up, which Garrett probably thought was un-fair being that their turbochargers offered so much more technology. One could agree a better comparison would be between Borg Warners EFR series vs Garrett GT/GTX series. We can probably say that the new GTW series of turbocharges are going to be much better suited to do what Precision turbo’s do, which is make great street and drag turbochargers. Many have reported terrible longevity with turbochargers that are not water cooled when it comes to road racing, but it seems that the limited full throttle pulls an owner can achieve on the street or at the drag strip don’t cause any problems for non-water cooled turbochargers.
If you have a street-car or drag-car that won’t see much road racing, than this line of turbocharger might be the performance your looking for without cleaning out the wallet.
