Hey guys I'm undergoing well almost finished building my full house rb26, I'm thinking of a single turbo kit and really interested in the precision range turbos, I was looking into the 6766 ball bearing turbo, anyone using these on their rb26 and what feedback I can get regarding it, also where is best site I can purchase this from

Thanks alot guys cheers

FP HTA SUPER 94. My opinion.

Maybe ask this in the precision turbo thread? That is what it's there for. Then when others want to search for a similar topic to yours there is bnot 71 different off shoots about Precision turbos. Pm "Lithium" and ask him what he recommends in the Forced Perfornance HTA RANGE. in particular the super 94. Would be similar to a 6766 but better I think.

This question is difficult to answer without being told what expectations are. 33GTRV is fairly on the money from what I've seen, if you want silly power and retain response a bit closer to typical midrange turbos (GT3582R->T04Z of the old generation) then the 6466 is probably good for that kind of thing.

If you are aiming at getting SERIOUS and thinking more about T51R type power but with lag closer to a run of the mill T04Z then I'd skip the 6766 and go straight to an 94HTA based turbo. While neither the Precision or FP crowds release maps if I were a betting man I'd say that if mapped - the 94HTA would provide a much wider map, as opposed to a taller (read: needs more boost for big power) map like the 6766.

This wouldn't be conventional thinking, but if it's a stock stroke RB26 then the .85 T3 Super94 HTA may sound like a weird suggestion (ie, mid-a/r T3 for a big power RB26?) might be the gun thing, they have proven to make BIG power and are a very solid turbo - also not hugely expensive for what they are and this turbo has been proven to work VERY well on a serious spec 4G63, which seem (exhaust side) to have a similar sweet spot to a stock stroke RB26 imho.... they just prefer more compressor vs pressure ratio. I would call this turbo capable of well over 600awkw on a suitably build RB26 on E85/race fuel and respectable response for the madness it is capable of: http://store.forcedperformance.net/merchant2/merchant.mvc?Screen=PROD&Store_Code=FP&Product_Code=NTFPSUPER94&Category_Code=SP. I'd confirm with FP, and also check with them if there actually are other exhaust housing options for it if you would prefer something else.

The GT3794R-HTA is more expensive, though a very reasonable alternative - makes a bit less power than a Super94 HTA though also spools slightly better, and has more turbine housing options and again I believe better suited to a very high flowing 6cyl than the Precision alternative:

I have the impression GTPumps.com.au are suppliers for ForcedPerformance turbos, otherwise they can be ordered at the links I provided above - which is how 34GeeTeeTee got his GT3076R-HTA (check the thread out here: http://www.skylinesaustralia.com/forums/topic/426059-forced-performance-hta-turbos/)

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By dbm7 · Posted

      He's right ~ there is no 'magic' with stuff like this ... it is more likely that in the process of looking for the short, the loom/wire 'incidentally' got moved in the process, thus removing the short ~ now, that maybe a wire (in a loom) rubbing against the edge of some grounded metal, that's worn through the insulation, causing the (now intermittent) short to ground. If one wire in a loom has been damaged in this fashion, it's reasonable to presume that other wires beside it may have also be damaged, and now exposed...you can bet the green crusty copper corrosion will start... ...that'd be a pisser, Murphy's Law steps right in as GTS observes...but worse, something like that is easier to find when shorted...ie; unplug bulb and fuse, and put multimeter in continuity mode so you get constant beep, and carefully poke about hoping to find if some movemet of the harness stop the beeping.... ...it's still all a bit Arnie tho' ..It'll be back... 😃

      Yeah, but knowledge of one wire's insulation worn through to short on earth implies the possibility of other wires doing the same. I had my power steering die, because the wire that runs to the solenoid valve on the rack runs in the same loom as the power wire for the O2 sensor. And when the O2 sensor/wire did something stupid and burnt part of that loom to death, the only indication was the shit(ter) fuel economy and the heavy steering. It took deep excavation of the looms in the bay to find the problem. Not wear through in that case, but similar shit.

      Mistakes were made, my R34 Story

      Ah, I thought he'd wired it to one of the spare ECU inputs! Too long ago since I read that post, ha ha. I've been arguing with radiators, harmonic balancers, alternators and rust since reading it.

      Correct. The ECU cannot read oil temp. (Well, I think it probably can in some situations. I did have the thought of potentially repinning the ECU when I was doing oil pressure). I am using this into the MPVI dongle, so that the MPVI dongle can read oil temperature. It is attached to a VDO gauge which is obviously calibrated to whatever curve the sender actually is using. This would be easy if I could setup a table of voltage to temperature like many sensors, but it appears I cannot do this and can only setup the transform rule which appears to be Input (voltage) x Multiplier, and add an offset. This to me means it MUST be linear. So it may be a complete waste of time wiring this into the ECU. The idea was that the MPVI3 has standalone logging. I wanted to use this instead of a laptop with serial cable (for wideband) for long datalogs. Given the wideband also has electric interference, I may never trust this either in a world where the serial wideband and the analog output wideband do not agree. Last time I did a trace I could see the two wideband traces follow each other, but one was a little leaner than the other. I plan on playing with voltage offsets and actually driving the thing to see how close they correlate. If they never correlate... then, well, maybe I'll never use either. Ideally I'd like to have the Analog wideband read ever so slightly leaner than the serial one, because the serial one is 'correct'. Tuning the car to be ever so slightly too-rich would be the aim. Not needing to have a laptop flying around in the footwell connected with cables is... an advantage. About the only one from the forced upgrade to MPVI3.
