Hyper Gear CT12 Highflow Turbos

**seamonsta** · 06-10-2009, 01:27 PM

Anyone on here had their CT12's highflowed by these guys? Interested in results (actual results not guessing!) Seems Ok to keep the factory look but no dyno results etc around so if anyone has first hand info please share away.

Didn't know they were doing that. I will ask them what sort of specs they end up with.

Specs etc on their website, but I would like to hear from someone who has installed them and run the car on a dyno, a couple of people have got sets done apparently but no concrete feedback (dyno printout/s) have appeared...yet.

I can't see any detailed specs here? http://www.digi-hardware.com/highflow.htm

Asked him and asked if they have any dyno/quarter mile results also.

More info on Supra forums, use Garrett bits and pieces to make them like a Nissan GTR upgrade, for a couple of grand to get @300 RwKW ?? and look standard when you pop da hood I am interested but want to see some proper evidence first that they can deliver. And before anyone says it, you won't get any single (a decent one) on there for this money.

Yes we can do CT12as. it will end up a sleeve bearing Gt2860RS. basically we build the chra then modify the turbine housing, comp housing with a customized back plate. Only done very few sets, I don't have any dyno sheets on them yet.
Procedure is very similar to the CT20s. photos at:

Link to SF?

Chris,
some chatter here about what goes into them etc, no-one has posted any varifiable results though, not that I doubt that @300 RwKw is achievable, on a GTR this is a piece of piss with those turbos, but I am interested in when full boost is in/how much lag etc. Someone out there has some and we need to sniff them out and see what they think of them.

yuea i heard about these guys recently.

highflows are like half the price as we are used too.

some info on other forums, ns.com etc, but no one with any first hand experience.

Regardless of who does the turbo rebuild, Make sure you get the factory exhaust manifolds ported out and the stock turbo pipework portmatched to the gaskets for maximum flow ...

Saw your posts on Supra, makes sense to do that but for the cost of extrude honing etc may as well just get new exhaust manifolds made and mount the turbos like on a Gtr and get new pipe work done, wouldn't be stealth but get a lot more power out of the whole setup then. Still interested to see what the outcome would be with stock manifolding etc though.
