my motor is currently getting rebuilt,

2.6 forged motor standard stroke 86mm pistons

Head has work done to it

Vct and custom billet cams also done to head

Precision 6766 cea billet wheel rated at 935 hp surge ported cover .84 twin scroll

6 boost twin scroll manifold

fuel system on pump fuel

Any one else run one of these 6766 billet turbos yet?

So this turbo is similar size to a gt3076r going off of the numbers its putting out?

It has a higher power rating than the 3076 I think... Yet still spools as early (well actually earlier than mine but thats different)...

Kurtis I don't like you any more, you have more powers than me :(

Nah just kidding :thumbsup:

Bump your boost up to 22psi like kurtis is running and it'll probably make close to it, its only like 6-7kw...

Does it make decent power still on slightly lower boost (19ish) or do you need to run the higher boost to make it meet its potential?

Haha. They seem like the exact same setups aye.

Im curious to see what it can make with a decat ad screamer pipe

Yeah I'd love a better exhaust to get that extra power but I'm pretty happy as is, BUT mine made it with the screamer, so Kurtis probably has more left....

Awesome result!!

Both setups made very similar power at lower boost levels, 19 is still around 340 I think

Makes it sound like like it'd be an interesting comparison with a Forced Performance GT3076R-HTA - the slightly improved spool over the GT3076R isn't surprising given its for intents and purposes a 52trim 76mm compressor (like the GT3076R-HTA) with the advantages that can come with billet goodness. Wonder what the PT5558 could do on full kill, though to start with its well proven its worth by matching the GT3076R in power while spooling better.

yeh, for me its definently proved itself as a good option for people wanting something a little different than a 3076r. Do they make twin scroll turbine housings for the 5558 or is that only for the larger frame turbos like yours Jez?

Nice, twin scroll then? With that setup the 1.15 probably wouldn't have been a bad idea, but that is still going to kick all kinds of ass.... I'd put pressure on and say I'd like to see it hit 600kw ;)

When is it going on the dyno?

Yeah Twin scroll. It feels fairly towy atm with it just running off the gate at 14psi. Will be very interesting to see how it compares with the old HKS T04Z. As for the tune just have to wait & see when mark has the time to come down. Hopefully within the next few weeks.

Pulled 604Hp at all 4 with T04Z on 24 psi So yeah Cant wait to see, Noticed the precision turbo is very Quiet which is a good thing I reckons.

    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
