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.

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

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 :(

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.

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

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 :(

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:

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

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.

      Duncan's V37.......race car?

      By Duncan · Posted

      Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
