I run a 6266 .84 T4 split pulse and made 352rwkw on 21psi that was with E70. Full boost about 4800. Though my Turbo is the Journal bearing one. If you buy BB alot more responsive around 4300rpm. 6266 is good size for 500kw with e85

Big difference between 600 or 700hp? I understand this came for a good price but obviously you aren't happy with it and the car has been built around this turbo now (exhaust cooler pipes etc) if 600 and a bit is your goal and you like response go a 6266 with a 1.0 rear. Your motor will love the larger turbine it will feel nicer down low off boost and it will make 600-650hp quite easily!

Are you on stock capacity? If so a .84 wont be too bad. But obviously you are gunna be leaning pretty hard on a stock motor chasing those numbers.

If your motor goes bang would you stay 2.6 or would you go stroker? If yes to stroker go the 1.0 if happy with 2.6 go .84

i already had a 3.5" tomei exhaust on the car, 3" dump no cat, cooler, pipe work all came with the turbo. sweet im just chasing info at the mo as ive read this thread a few times over since i put this turbo on. yeah shes still a 2.6 if she goes ill be looking at going 2.7 or 2.8. i know she'll get leaned on abit on a stock motor to make those numbers but she is my daily driven car and the occasional track/drag day. for the time been 600 would be the most but once built 700 will be my goal

Hey mate, i saw you were selling your turbo on facebook and was going to comme t but didnt want to f**k up your sale.. 20psi @ 5000rpm does not sound right

I use a 6466 Gen2 with .82 Vband single entry housing on my built RB26, which has a Nissan 2.6 crank and HKS 272 10.2mm cams

On E85, it makes 30psi by about 4500rpm, and makes 710rwhp

I would highly recommend this to anyone.. it has less lag than my previous 2860-5 setup, which i personally did not think was laggy.. but theres no contest when compared to a big single, it comes on like an absolute motherf**ker

I reckon 1.00 will be too large on a 2.6

Read my mini review of my setup a couple posts up

Cheers mate. 

I was reading the thread for about half an hour. Must of missed the last page..

I have a 1.0 on a 6766 that's bolted to a 2.6 and its fine. E85, 272/264 9.1mm cams and a decent amount of head work and I don't think its laggy at all. I would see full boost (currently 23psi) no later than 4500rpm

Ive decided to go with the gen 2 6266 with a t3 .82 rear on my basic built 25 (cams,springs,studs and forged).. I already had a manifold otherwise i would have liked to go the .82 T4 twinscroll.. but none the less ill be pushing it and hoping to post some decent results in the coming months.. the decision between the 62mm and the 64mm was tough but i decided to go with a slightly more street friendly turbo as after RW17 it will be mainly used around town...

So many posts to go through and not enough time :(

So what are people making nowadays with a 6766, 1.0 split rear on E85 on a stock stroke RB26?

My girlfriend seems to think her car is a bit of a nugget and I want to prove her wrong. It runs 138mph in full street trim and makes 485rwkw at 23psi on the Unigoup dyno which is a pretty tough dyno from my experience

Not sure about 6766 but my brother Inlaw, who bought my previous Gtr went 6466 1.00 and maxed the turbo out on his setup at 553kw at 40psi

built 2.6, mild head/cams, 3.5" exhaust etc on United e85 tuned @ Jez .

Hi, I am currently still two Td05 g18 billet turbos. I would also like to switch to a singel Precision Turbo.  

My Setup:

 Build Rb26,

ported Head,

Oversize Valve, 

270cams 10.8 mm,

Revlimit: 8500,

1000cc Fic Injectors,

Walbro 450l Fuelpump.

Fuel: 102 oktan, 

Boost max 30psi

I want to more than 800hp on the Flywheel. 

I do not know which turbo I should buy. The 6466 bb or the 6766 bb? And if what ar? I apologize for my bad english :)

Well. On a near stock head with a quick home port job, stock valves with 80lb springs and a set of drop ins i made near enough to 550awkw on a 2.8 with a 6466 with 84 rear. 4 inch dump was at 49psi. The turbos like to be run hard.

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
