You know I'm gonna hold you to that and make a point to drop in now ! 😄 it's only 2300km or so away which is peanuts for us in the NT.

How is the place ? Gotta be better than here with the extremely high crime and f**kwit rate. I grew up on the Boulevard, raced motocross at Waaia and went to Gowrie Street primary as a little tacker in the 80s - loved it down there back then. My neice still lives there so I'll be down at some stage, so your 33 better be running by then 👍

Being Victoria, how do you think you'll go with registration for it ? I think about this for our single turbo GTRs when we move away...NT is a bit like who you know for rego sometimes as we have yearly pit inspections for cars over 10 years old which complicates matters.

That said you still see shit like this running around every day - at least the have some windows

What a surprise. Cops are f**ken useless here...

Sounds like a plan!

Yeah Shepp is OK. It's got it's problems but where doesn't!  My first house was in Will's Street which was just off the Boulevard. It's a nice area. 

One smart yet dumb things I decided way back was to not deregister it knowing re-registration would be difficult going RB30. It means I've paid $7500 or so of rego without ever touching the road!  Thank God they went up in value!

I would imagine there would be some pretty interesting cars up in the NT! 🤣🤣

Finally getting some traction on the white 32.

Mountain of parts, and Amayama finally delivered after about 18 weeks.

Chopped the varex control crap out of the muffler

Replaced Trust 13 row oil cooler and flushed lines after engine failure

Modified front pipe to suit new Precision turbo

New Precision turbo gen1 ball bearing 6266 with divided T4 0.84 a/r. Old T78 is in there somewhere

Long engine starting to go back together with the CP pistons and Spool I beam rods. Head is stock apart from ARP2000 head studs, Tomei 1.2mm head gasket and Supertech single valve springs. Bottom end got the ARP main studs on a factory 26 crank. Still waiting for the Hi Octane sump to come back and then engine can go in.

To top it off also getting rid of the NPC single and have a new ATS twin plate carbon to go in.

Hopefully running by July.

I can detect sleepless nights ahead 😂

Very exciting, will be great to see the updates!

Yeah man full steam ahead now. Give me 2 months and should be re-regoed and back on the road 👍

I for one can't wait to see the 6266 real world. People talk a lot of shit on here but I truly am impressed by the Precisions overall.

I know your style, it's full send till it's done.

I'm a lazy prick, I'll take 3 years to do what you would do in 2 months LOL.

I'm a Precision fan too, just run an OPR and an oil filter and it will live much longer than other fancy turbos.

You go to WTAC and you mainly see two brands of turbos, it's either Precision or Garrett for a reason.

Some of the tribal "rah this turbo brand" or "rah that turbo brand" does my head in, especially where people give "advice" which is pretty clearly actually based on their biases.   Ironically a build I'm involved with is also centered around a divided hotside Precision PT6266 Gen2 on a "true" split pulse cast manifold and we're going to be using it on a 2JZGTE.   The owner had been convinced to upgrade to an EFR8374 when his car had pretty bad lag issues which were actually nothing to do with the turbo itself, and it didn't have a lot of miles on - like yours I expect it will be a super effective street setup which will probably surprise some people in terms of the power and response it's capable of.

Half the time the issues the bigger name turbos have are to do installation or how they're matched to the engine they're on.   I've seen some turbo speed data on how some Precisions are used on bigger builds and it's amazing how far into "overspeed" territory their compressors stay efficient - imho a certain amount of their reliability reputation is effectively them being a victim of their own success in that fact.

Aside from you know, the likes of Tilton and RP968 but they are pretty much having their own private WTAC battle half the time so I guess don't count.

After ripping off the HKS turbo on my 2.8 blue 32 and going with the 6466 I was astounded by the overall improvement everywhere in the power curve and peak power.

Considering that 6466 on my 2.8 is over 450kw at 22psi on 98ron and over 600kw at 32psi on E85, I would expect the 6266 on the 2.6 to be maybe 400kw on 98ron and 500kw on E85 at similar boost levels. Sound around the ballpark ?

With >600kw from the 6466 I'm guessing that's a hub dyno, in which case I'd say your goals seem super realistic.  I'm kinda hoping to see mid 500kw area without being silly on the Gen2 a bit with E85 on the hub dyno I use and 400kw easily on 98ron.   I'm not 100% sure about the Gen1s as the 6466s really overshadowed the hell out of them when they came out (and lets be real, the 6466s were basically a game changer when they came out and are still not easy to beat in terms of how flexible they are in terms of power, response and what they work on) but I doubt there is THAT much difference so again, feels like the numbers should be realistic.

Yeah 611kw gen2 6466 1.0 a/r results from Morpowa's Mainline Prohub dyno, printout posted in the other build thead and 26 results thread. I know Precision power ratings are to be taken with a grain of salt, with the gen2 6466 is indicated at being 900hp rated.

The 6266 gen1 vs gen2 power ratings are 735 vs 800hp so really sort of approximating estimates.

Ah nice, yeah solid result.  Hp ratings are so frustrating, who knows what conditions they're defining for making that hp etc - even if they can't do compressor maps it'd be lovely if they could say "Flows up to x lb/min at x boost" kind of thing a bit like that excel datasheet I compiled for a while for different turbos where the info was available.

The .84/6266 combo seems like it'll be a nice one on a 2.6 anyway, look forward to seeing how it goes

Well, after a 20 week wait.....

Hi Octane finally finished the sump so engine can go back in.

[Duncan]

Nothing is quick these days, is it. Are you setting the diff backlash or do you need to send it out again?

[BK]

We're setting the backlash. "Shouldn't" need to change it as the same front centre, crown wheel and pinion are going back in that came out of it but we will see.

[BK]

Pick up and baffles in, pinion setup and fitted (took 6 thou out of clearance) and sump on with Threebond 1207C 👍

[BK]

So after going away for work for a week I thought we better hook into the white 32 and look at getting the engine in. I came back to this:

The old man Lyle got itchy feet while I was away and not only got the engine in by himself, but installed the full oil cooler system, power steering pump, catch can, aircon compressor, twin blitz blow off valves, alternator, all belts and pulleys, intercooler and all pipes, the 6266 turbo, ATS twin plate clutch, front diff and setup, rebuilt clutch master cylinder. Also replaced the Speedflow 602 series 40 micron fuel filter, tig modified the new sump with extra AN10 and AN4 fittings for sump breather and OPRT40 turbo oil reg.

I must say it's pretty impressive for a 77 year old...

[BK]

I have 4 weeks to have to this piece of shit ready and registered for drags and motorkhana on 2nd - 4th September for RCN08. Gearbox, drive shafts and exhaust up. Had a hold up sourcing the correct 20mm bearing carrier for the new ATS twin plate carbon clutch. Also fitted a Nismo chromoly release fork pivot to the box before it went in too.

Ordered some fittings and hose to get this fitted to make Johnny @Dose Pipe Sutututu happy....

Need to plumb into sump at the AN4 fitting here below the turbo oil drain in the next week or so 

[Shoota_77]

I dunno how you find the time….  I can’t find enough time to work on one car let alone 3 of them!  Oh how I wish others successes were contagious!  

[BK]

Dude, I am f**ked up at the moment. Working on 3 GTRs, a WRX, a Ford Territory, working 60  - 80 hours a week on electrical with every second one away from the cars, looking after 2 little girls at 4 and 5 years old and the house shit and a missus that fckn hates me doing anything car related (even though the WRX is basically fckn hers ! - hardly drive it). Oh and had Covid this month for the first time too......

I guess I'm just in superfreak mode at the moment which has been sustained for a while - like 4 years worth. This white car blow up has cost us the best part of a year, so I'm lucky Dad (Lyle) is an awesome performance mechanic and actually fills in the gaps for me a little (lot) bit.

I actually hate working on GTRs as they're such a prick of a platform to do anything on. I guess I wouldn't do if they weren't so bloody awesome to drive. That's the key part - I want to get to a point of driving them more than working on them which seems to be the GTR way of life.

Anyway, back to it....😖

Whatever shit you're on, I need a bit of it!  Send a bottle back to Shepp will ya!?

Maybe I'm just in a rut! 🤣

Keep it up, you're smashing it!

[Dose Pipe Sutututu]

Hope you're feeling better!

Naice work on the OPR 😊
