I have a Precision 6262 on my R32 GTR now. Making 355kw - 475hp at all four wheels on 20psi running BP Ultimate.

Comes on hard from 3500rpm so no less lag then the twin HKS GT-SS I previously had. I went for the 6262 over the 6265 as i was worried about the lag for street use.

gtr32g do you have dyno sheet showing reference to boost power and rpm? I was seriously concidering a 6765 for more power over my 35r but after reading that link I might steer clear :(

Next time im at my tuner will get a copy printed off and send you a pm.

Out of interest sake, Precision are now releasing versions previously with the "65" hotside with a "66" billet "CEA" turbine, which they claim more hp with similar or better response. This means the PT6265 and PT6765 could be superceeded with the PT6266 and PT6766...

Enough said...

6262 6265 difference is minimal in response anyway.

a few of us are using the precision turbos and couldent be happier with the way they perform, my rb26 with a 6765 T3 .82 made a lazy 600rwhp on 26psi, another mates 26/30 with the same turbo makes 600rwhp on 26psi, we also put a 6262 T4 .84 on my old man's 32GTR and with a peice of shit hks log manifold made an easy 500hp @ the wheels on only 19psi on straight 98 pump fuel with stock bottem end, good proof for the people whinging about having to run 35psi and e85 to get good power results.. its a load of bullshit, my mate with the 26/30 gained 40hp @ the wheels with a 2psi boost increase, and during tuning his car was making 430rwhp on something like 14psi. these turbos dont stop making power, you can just keep going and going and the car will just keep making power.

Just saw your graph in the RB26 upgrade thread... What diff ratio do you have?

these results impress me alot, and as u said aload of crap but running big boost to see power..

i think it just comes down to some peoples tune or set up being wrong for those who arnt making the power...

these results also back up all the power figues the guys make in there supras on supraforums.com, if u get a chance and sign up on that site and go to the dyno tuning section

theres so much interesting reading on pt 6265-6266, 6567 and 6566 and 7175 on both pump and e85, most of there supras are making 700-900 rwhp with 67mm turbos- INCREDIBLE

get on board :)

I'd like to see a dyno sheet.... 6262 is not GT-SS response... I've driven 2 GTR's with 6262 PT turbos is two difernet trims.. they were laggier. They're not a bad turbo as compared to some of the PT range.

700USAHP = 500 AUS HP

Yeah... if your lucky. seen a couple of '1000hp' honda's with stock gearboxes.. ha ha ha ha

700USAHP = 500 AUS HP

i think thats a lil exadurated... if this was true they wouldnt b running 140-150 mph, yes they r manual but they r also weighty...

we could argue bout this for days, but there strip times back up the dyno figures...

so many haters of the pt range out there :(

its all good though, the haters can hate. more performance gains for you and me my friend ...

PJ, can u shed anymore light on the "6766" im so keen to get a 6765 on my 2.8 but if this is close to coming out and out performs ill lean towards the newer

Hi Jake, I haven't been involved with Precision as I was earlier this year, but it doesn't change my opinion on them one bit which was based on real experiences with the cars I had driven and the two Precision's I've had on my own car.

Sure US figures spell out some pretty serious GST to us, but that's with all readings on particular dyno's.

That's why we bit the bullet and tried everything for ourselves on local soil.

It's hard to understand the BS that people have written about them, but I figure people can think what they like, we're the ones laughing in the end :action-smiley-069:

Edited by PJ.

I don't doubt some of them are making the numbers...just a lot of BS comes from the land of yank

eg, I saw 1 "result" of a Gt2871 on a SR20 making 500rwhp...now we all know that isn't going to happen. SO anything out of the US is disregard until there are a number of results here locally of similar nature.

P.J not taking anything away from you, but we never got to see the S14 run, all we got was a few dyno sheets, which I'm sure you know are easy to fudge (my 33 "made" 400rwkws with a stock turbo)

Which is why, we are "haters"

Its just a natural reaction for everyone who has grown up in the era of infomertials to not want this "super mega awesome best ever product" just because a couple of workshops say they are the best thing ever

If we could see some normal results, at low boost levels, I can only speak for myself here, I would start to take a more objective view

    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go. 
    • The roof is wrapped
    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
    • The downside of this is when you try to track the car, as soon as you hit ABS you get introduced to a unbled system. I want to avoid this. I do not want to bleed/flush/jack up the car twice just to bleed the f**kin car.
