Marty Posted July 15, 2007 Share Posted July 15, 2007 Im running a SPSSGT850W Which is basically T67, built by sound performance, with a low friction cartridge, i dont think they are too expensive to buy from the states either. Mine made nearly 570bhp at only 1.1bar. 490 rwhp. Quote Link to comment Share on other sites More sharing options...
Mike B Posted July 15, 2007 Share Posted July 15, 2007 Not so much a downer, but I don't think it's as good as it could be. Just the fact some have DAF written on them....and they are the size of a house. Seriously, compared to the T67 they are physically massive. They seem to work well enough and being from a Diesel truck they *should* be fairly robust! I mentioned the GT4088R as some probably read 4088 and think it's all singing all dancing. The GT4088R is more like the T67. glad I bought the GT4088R then... jamie did speak highly of his non dbb, it was one of the last .85 non divided housings I think, and he used a few different turbos. My 35R .68ar did run out of puff over 5.5k, even with cams, so I'm hoping the new 4088r ar.95 will have longer legs with not so much lag. we will see next week! does seem bigger than a 35 in situ but it's not mahoosive....

Mike B Posted July 15, 2007 Share Posted July 15, 2007 Note about Spool!!! - IT'S DEPENDANT ON LOAD. So it's dependant on the gear you are in. LOL i used to get positive boost on my 35r at 800 rpm in 6th but it didn't bite properly until 2.7 / 3k Quote Link to comment Share on other sites More sharing options...
Branners Posted July 15, 2007 Share Posted July 15, 2007 seems theres a LOT of single turbo supras out there now. Perhaps its time to start a thread to see who has what, sort of a single turbo registry. JB Quote Link to comment Share on other sites More sharing options...

Mike B Posted July 15, 2007 Share Posted July 15, 2007 I really liked the list Jamie P started with some "rough" performance figures in.. to help people looking at single weigh their options on spool and power, but it degenerated into a handbag fight within 10 posts... shame!

I wouldnt even try to guess my power as it would never be right. Its when a wild claim on power is made about a turbo that it could get messy, so Im tempted to keep away from the power figures.

matt k Posted July 15, 2007 Share Posted July 15, 2007 I've just put a HKS T04R kit on my UK spec auto, i've not had the car properly mapped yet so can't really comment on its performance, my mate has a UK spec auto with a GT35R on it and is very impressive, as others have said it makes boost really low down.

Nic Posted July 16, 2007 Share Posted July 16, 2007 Nic what's that in real money? (BHP) and is that rw(ps) or at the fly? Just checked conversions here: http://www.onlineconversion.com/power.htm 542PS = 542HP (Metric Horse Power) 542PS = 535hp (International Horse Power) Quote Link to comment Share on other sites More sharing options...
ndwgolf Posted July 16, 2007 Share Posted July 16, 2007 What's your timing and fueling controlled by looks like it's suffering from the stock ECU's sequential transition. Not sure what you are talking about but it goes like sh*t off a shovel, the ECU is a HKS thingie (check out the garage thing) it has all the details in there "enjoy" Quote Link to comment Share on other sites More sharing options...

ndwgolf Posted July 16, 2007 Share Posted July 16, 2007 No Plobelem, I wasn't at the Dyno shop when they tested the car but like I said before it goes faster than most people would care to drive at, and gets there pretty dam fast as well.

bolarbag Posted July 16, 2007 Share Posted July 16, 2007 Is there any way to get that GT35R to keep singing after 6K rpm? Maybe with the addition of cams? Whats the closest thing to it....going up the garret GT range the GT4088R? Quote Link to comment Share on other sites More sharing options...
Ian C Posted July 16, 2007 Share Posted July 16, 2007 Lots of info on the performance of a T67 and a T67DBB: http://www.mkivsupra.net/vbb/showthread.php?t=68090 Bear in mind these were datalogged and recorded figures in as repeatable circumstances as possible for me, and not someone glancing at their rev counter and guessing -Ian PS dare I even ask why your T61 is broken, or can we guess?

Bigger cams, I have in256/ex264, dyno here: http://www.mkivsupra.net/vbb/showpost.php?p=1506564&postcount=24 Yes the GT4088R is the next size up.

bolarbag Posted July 16, 2007 Share Posted July 16, 2007 Bigger cams, I have in256/ex264, dyno here: GT35R... So 264/264, would 272/272 be too wild? I know it would eliminate some response but who cars when its on song by 3K? Just looks like the perfect response turbo, but the power band tails off too early, how about a bigger intake plenum? Virtual Works/ Greddy e.t.c would that increase the powerband? I know HKS do a Garret GT35 version is it any different to the standard Garret?

And just cause it drops a bit, it doesn't mean you're suddenly not accelerating quickly....it's all relative. Quote Link to comment Share on other sites More sharing options...
Guest Terry S Posted July 16, 2007 Share Posted July 16, 2007 Jon turbo selection all depends what you want from the car. It is generally a compromise. PM me if you want. Quote Link to comment Share on other sites More sharing options...

And just cause it drops a bit, it doesn't mean you're suddenly not accelerating quickly....it's all relative. It still pulls very strong >6K rpm, yes it may drop off slightly, but if you look at my dyno you've still got a fair bit of HP. Quote Link to comment Share on other sites More sharing options...

We have long roads up here in Scotland, and I'm gonna need all the help I can get when it comes to the long up hill straight at Knockhill, my challenger is driving a slightly modified supercharged exige S2, I figure thats where I can catch him up!

blitzer Posted July 18, 2007 Share Posted July 18, 2007 Lots of good infos here , as a rough guide about "size/spoolup/max hp" is this correct for non-ball bearing version of these turbos? Gt35r -> Gt4082 -> T61 -> Gt4088 -> T67 Thanks in advance for any input Adriano Quote Link to comment Share on other sites More sharing options...
