adi2009 Posted November 15, 2011 Share Posted November 15, 2011 Does anyone know how the two turbo's would compare against each other. I am considering choosing a quick spooling turbo to use with a SP QSV. I am currently using a Precision T61 journal bearing turbo and want something which is more responsive but around the same power levels.

johnny g Posted November 15, 2011 Share Posted November 15, 2011 I believe the GTX35r would provide and awesome, rapid response car. If you got that on a T4 footprint, with a QSV, you'd effectively have a lag-free car, with 550-600bhp on tap. Quote Link to comment Share on other sites More sharing options...
Scott Posted November 15, 2011 Share Posted November 15, 2011 Is the GTX35r not more of a 700+hp turbo? I know the old GT35r was around the 600 mark maximum but from what I've been reading the GTX30r is more comparible to the GT35r. Quote Link to comment Share on other sites More sharing options...
Dan_Turism0 Posted November 15, 2011 Share Posted November 15, 2011 have you thought about the S362 Batmowheel? Quote Link to comment Share on other sites More sharing options...

I know the old GT35r was around the 600 mark maximum but from what I've been reading the GTX30r is more comparible to the GT35r. IIRC, the GTX35R is GT35R + 10% or thereabouts. I know Nic got somewhere in the region of 540bhp @ 1.4bar on his, so, 10% is nudging 580-600. And it's meant to spool better than a GT35R. Good shout on the S362 as well.

Noz Posted November 15, 2011 Share Posted November 15, 2011 s362 seems to be whats compared to the gt35r loads from what id been reading up ages ago when i was trying to decide what turbo to go for. would be good to see some dyno's on same set up with swapping them over.

I've read reports of 2.5bar and 700+RWHP on the GTX35r though. The GT35r was seriously out of puff by 2.0bar. Granted if 600hp @ 1.4bar is the goal then it's a good choice but I would be more inclined to go for a smaller turbo at slightly higher boost if I wanted 600hp. The GTX30r is meant to be right on the money for 600hp. Quote Link to comment Share on other sites More sharing options...
JamieP Posted November 15, 2011 Share Posted November 15, 2011 Im a big precision fan myself, In this supra board ive not seen any garrett or borg warner able to match precision for spool time or power on the same size turbos. Quote Link to comment Share on other sites More sharing options...
adi2009 Posted November 16, 2011 Author Share Posted November 16, 2011 I am leaning towards the 6266 billet dbb. I need to decide on the divided housing size. Should I be looking at the .82 A/R divided or a 1.0 A/R divided housing on the exhaust side??? Quote Link to comment Share on other sites More sharing options...
Luxluc Posted November 16, 2011 Share Posted November 16, 2011 Im a big precision fan myself, In this supra board ive not seen any garrett or borg warner able to match precision for spool time or power on the same size turbos. Regarding the small size tubbies, there are no big differences in Ricky's 67mm Precision turbo vs my 66mm BW unit, both in spool and power.

If you're happy with 550-600 bhp, I would go with the 0.82 A/R and a twin WG manif ... you'll have a very quick spooling turbo. Quote Link to comment Share on other sites More sharing options...
Nic Posted November 17, 2011 Share Posted November 17, 2011 (edited) Does anyone know how the two turbo's would compare against each other. I am considering choosing a quick spooling turbo to use with a SP QSV. I am currently using a Precision T61 journal bearing turbo and want something which is more responsive but around the same power levels. Have a read of this comparison between Garrett Vs. Precision Vs. Borg Warner Turbochargers I don't think you'll be disappointed with either choice. As a comparison my GT3582R made positive boost at just over 2K rpm and around 540hp at 1.4bar (dyno graph in my garage HERE) the GTX3582R is suppose to spool up quicker and flow 10% more.

Nic, in what great does your car produce positive boost at just of 2K RPM? Quote Link to comment Share on other sites More sharing options...
caseys Posted November 18, 2011 Share Posted November 18, 2011 Turbo Dynamics when I popped in to see them and talk about a new exhaust housing I asked about the GTX35R vs the BW EFR turbos they are looking to offer next year and they said the EFR is leagues ahead of the GTX range from garrett. They don't deal with Precision so couldn't compare those, but after asking if it'd be worth swapping my GT for a GTX they said hold off for the BW units.

Guigsy Posted November 18, 2011 Share Posted November 18, 2011 My gt3582r also mapped to 520bhp a little while ago at 1.4 bar if that helps anyone. Same turbo and within 20 bhp of nic. Spools great Quote Link to comment Share on other sites More sharing options...
