Goodfellas Posted September 7, 2010 Share Posted September 7, 2010 (edited) Hey guys I am in the process of getting everything together for my 26 conversion into my s13. This will be a dedicated drift car so I am chasing response over outright power. But I am really keen to go single, as everything is a very tight fit in my bay as I have tubs etc. So if anyone could help with some advice of: Turbo and Manifold choice Loose Power Figures I currently have R33 block Block decked, honed, bored, chemically cleaned Shotpeened rods ARP rod bolts ACL forged pistons 20 thou over Mahle rings King bearings Ported and Polished head Reground cams ARP head studs Permaseal head gasket Custom 7L RWD sump Sard 700cc injectors NGK plugs Tomei oil restrictor N1 oil pump Thanks in advance Edited September 7, 2010 by Goodfellas Link to comment https://www.sau.com.au/forums/topic/336011-built-rb26-turbo-selection-for-drift/ Share on other sites More sharing options...
R31Nismoid Posted September 7, 2010 Share Posted September 7, 2010 Garrett -9s or a GT3076 Failing that go and look @ the dyno sticky threads.

STATUS Posted September 8, 2010 Share Posted September 8, 2010 What is your abilty? as size is dependant on driver quality and chasis setup... the more you progress the more and more grip you chase in the rear (many of us run semis on the rear 265-285) in size end so obviously you need more power to turn them. For entry level to mid i recommend GT3076 (with the larger rear) or a 10cm T67 is also a killer drift setup for RB26 (i had a few T3 versions around for about $1200) for mid to high level i recommend Gt3540 or equivalent (we run the blitz K5 which performs better but cost twice as much) Link to comment https://www.sau.com.au/forums/topic/336011-built-rb26-turbo-selection-for-drift/#findComment-5435945 Share on other sites More sharing options...
Goodfellas Posted September 8, 2010 Author Share Posted September 8, 2010 Well I would say I am entry to mid level, my chassis has tubs, removable rad support, full seam welded, and full bolt in cage. Suspension set up is JIC coilovers,adjustable everything blah blah blah... So t67 25g 10cm rear??? thats kinda what i had in mind, any others????

Lithium Posted September 8, 2010 Share Posted September 8, 2010 GT3582R with a 1.06 T4 Twin scroll turbine housing with a suitable manifold, similar spool to a GT3076R but more top end.

R31Nismoid Posted September 8, 2010 Share Posted September 8, 2010 Define "smilar spool" Larger rear housing, larger turbo comp side, that combination dont usually make for 'similar' by my definition Link to comment https://www.sau.com.au/forums/topic/336011-built-rb26-turbo-selection-for-drift/#findComment-5436971 Share on other sites More sharing options...
STATUS Posted September 8, 2010 Share Posted September 8, 2010 have you actually run one of these turboes?looks to cheap to be true yeah 3 or 4 now. I tried one myself for a while before letting a few of my customers buy one off ebay.

RBceffy25 Posted September 8, 2010 Share Posted September 8, 2010 Trent, Can we please have some dynographs on this turbo? That would be fantastic! Also, what is the response of this turbo comparable to? I am currenlty building up a street RB25 with all the fruit to run between 270-300rwkw and I just might be in the market for a new turbo.... Will be runnig forged bottem end, mildly ported head with upgraded springs, poncams, front facing plenum,haltech platinum ecu etc, etc. I have a VG30 turbo i was planning on getting highflowed but this looks like a gret option also.

Lithium Posted September 8, 2010 Share Posted September 8, 2010 Define "smilar spool" Larger rear housing, larger turbo comp side, that combination dont usually make for 'similar' by my definition I know this, sounds a bit strange but it is honestly the reality - I think the twin scroll setup makes up for a lot of it. The twin scroll GT3582R cars I've been in are honestly feel too good to be true, the guys I know who have gone from single entry to twin scroll GT35 setups have improved spool by around 500rpm (pretty much the difference between an equivalent GT30R and GT35R) and make more midrange torque for an equivalent boost level. I haven't been in a Skyline with a TS GT35R *yet* but given they are a 6, the gains are only going to be at least as good as the 4cyl ones I've been in. From the cars I've experienced I'd expect 1bar before 4000rpm on an RB25 with good manifolding, and heaps of midrange. Naturally the TS setup on a GT3076R would be better again, but I'd say ridiculous on an RB26. Think of it this way, twin GT2860-5s have the combined equivalent "wheel" surface area of a T04Z... which spools better?

PIG747 Posted September 9, 2010 Share Posted September 9, 2010 3076 with a .82 rear housing is good on an rb26 and as other have said you will get about 330kw which is plenty of power i have one for sale atm because i've decided to upgrade it Turbo Link to comment https://www.sau.com.au/forums/topic/336011-built-rb26-turbo-selection-for-drift/#findComment-5437716 Share on other sites More sharing options...

Simonster Posted September 17, 2010 Share Posted September 17, 2010 give strong consideration to the choice of your oil pump. I had one the same as yours, failed today on a brand new engine and 4500km and never saw the limiter once...

BoostdR Posted September 18, 2010 Share Posted September 18, 2010 6boost manifold. if you have a twin scroll turbo make sure u have a split pulse manifold to compliment as for the oil pump, this is the easiest option Oil pump gears I haven't used on but it looks ok. I would confirm the correct width Link to comment https://www.sau.com.au/forums/topic/336011-built-rb26-turbo-selection-for-drift/#findComment-5452958 Share on other sites More sharing options...
RBceffy25 Posted October 17, 2010 Share Posted October 17, 2010 will do, away till monday. Oh wow! I totally forgot about this thread. I have ditched the high flow option and I am in the market for either a HKS GT3037 pro s or MHI T67 10cm. I thought I might as well considering I'm pretty much going all out on the long motor. Any thoughts or Dyno read outs of either of these turbo's on RB25 would be awesome, thanks Trent.

GTScotT Posted October 17, 2010 Share Posted October 17, 2010 It seems more of us need to jump on this t67 bandwagon. More dyno graphs would be excellent.
