Jellybean Posted June 6, 2012 Share Posted June 6, 2012 I want a fast road , drivable setup; I dont care about quoting horsepower just want a quick setup but drivable and instant responce Has anybody had any experience with the GTX series yet (35 or 42R) or how would they compare to the precision Turbo T67 (just curious as I was advised to get the T67) I would also like the car to spool quicker than BPU if possible, pin you to the back window, not looking for top speed just instant power My friend had the HKS 2835 kit on his Chaser and said it was superior on the road compared to the T78 on his Rx7; it was actually a practical road setup Is it possible to put on a larger turbo later, without the need to change the Manifold, not too sure about T4 divied, V band T3 etc fitments Quote Link to comment Share on other sites More sharing options...
Kaan W Posted June 6, 2012 Share Posted June 6, 2012 What about the GTK series? Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted June 6, 2012 Share Posted June 6, 2012 I cant fault the Borg Warner bullseye power turbo i have, it spools super fast. I would go batmowheel range now though. Quote Link to comment Share on other sites More sharing options...
Jellybean Posted June 6, 2012 Author Share Posted June 6, 2012 I cant fault the Borg Warner bullseye power turbo i have, it spools super fast. I would go batmowheel range now though. I want to stick with Garrett or precision Turbo; they are around years but definetly will go with the Full race manifold unless somebody has a good reason to go Cast Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted June 6, 2012 Share Posted June 6, 2012 they are around years If you're looking for a decent turbo manufacturer, Borg Warner is one of the best firms out there. They make all kinds of OEM turbos, including the clever variable ones for the 911 Turbos. Been around rather a long time Quote Link to comment Share on other sites More sharing options...
Dan_Turism0 Posted June 6, 2012 Share Posted June 6, 2012 agreed i'd go BW something like a S362 Batmowheel would provide very good spool Quote Link to comment Share on other sites More sharing options...
Kaan W Posted June 6, 2012 Share Posted June 6, 2012 The turbonetics GTK series are suppost to spool crazy quick but dont know much history with them reliability wise. Quote Link to comment Share on other sites More sharing options...
Kirk Posted June 6, 2012 Share Posted June 6, 2012 If it was my money I'd go for a GTX35. Great spool and response with good power potential although not the cheapest option but then again quality never is. Quote Link to comment Share on other sites More sharing options...
Ricky49 Posted June 6, 2012 Share Posted June 6, 2012 The BW are disappointing for all the hype that was talked about them. Id go with PT 67 CEA. Quote Link to comment Share on other sites More sharing options...

sideexitsupra Posted June 6, 2012 Share Posted June 6, 2012 Check put the Whifbitz manifolds as they have been shown to improve spool. Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted June 6, 2012 Share Posted June 6, 2012 Don’t forget to look at a descent exhaust manifold as the design assists with spooling too. No point getting an expensive turbo with a crap turbulent manifold. May be worth looking at getting the manifold and the exhaust side of the turbo ceramic coated (Zircotec coating) as well.

Kirk Posted June 6, 2012 Share Posted June 6, 2012 Agree'd. Id also be looking at a twin scroll manifold as well. Quote Link to comment Share on other sites More sharing options...
sdistc Posted June 6, 2012 Share Posted June 6, 2012 Agree'd. Id also be looking at a twin scroll manifold as well. I'm watching with interest the Sound Performance manifold testing - to see if twin scroll really *does* make that much difference. Twin wastegate I can understand, but the whole twin scroll manifold / divided / undivided turbo scenario seems quite a murky topic. On topic, there is only a little bit of testing data available for the GTX series, and it suggests mostly that the gains are made at higher boost pressures. I run a Garrett 4294R which does pretty well, but not the fastest spooling turbo out there. Of course, any turbo over 65 mm will probably not spool or respond instantly, so I'm not sure if the 42 series is the size you are looking for.

Alex Posted June 6, 2012 Share Posted June 6, 2012 Anything around 61mm (+/- 2mm) is really responsive on the road, if you want the punch to the red line I'd suggest trying a .8x A/R on the exhaust with a T61. Full boost by 3400rpm on a stock block is achievable, which means even with a slightly short shift you'll drop into the power band. Quote Link to comment Share on other sites More sharing options...
JamieP Posted June 6, 2012 Share Posted June 6, 2012 The BW are disappointing for all the hype that was talked about them. Id go with PT 67 CEA. Agreed, CEA billet Precision ftw, fastest street car in the world runs Precision turbos. Don’t forget to look at a descent exhaust manifold as the design assists with spooling too.

j_jza80 Posted June 6, 2012 Share Posted June 6, 2012 I'd maybe look at the GTX30R, still over 500hp potential but will spool noticeably faster than BPU. You could go cast manifold but it ruins the sound - which matters IMO. Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted June 6, 2012 Share Posted June 6, 2012 Cant beat the HKS manifold IMO HKS manifolds are nice but my manifold out performed the HKS in back to back testing. 800 rpm earlier spool up and nothing else was changed. And my HKS manifold along with other HKS manifolds we've used on track cars crack. Never had one of mine crack as yet. Quote Link to comment Share on other sites More sharing options...
dandan Posted June 7, 2012 Share Posted June 7, 2012 .....unless somebody has a good reason to go Cast Assuming you are looking for 650hp+ I wouldn't (and didn't) consider anything other than a cast manifold. The downside is the "kit" side of things is just not common so you're into fabrication and that needs to be top notch to get max performcae from a cast manifold setup. The gains you make in spool and response are not to be sniffed at for a road car. If you want more than 650hp and/or can't get the fabrication work done then look for the best tubular around IMHO.
