Precision Billet Turbos

[Piggaz]

That price, it'll be the journal bearing option.

I was thinking about getting a Precision PT6262 for my RB26/30, have had a look on eBay $1137.28 delivered and Powertune Australia looks to have dropped their prices to$1150, only $13 difference so i ordered through Powertune Australia as they have warranty for the turbos as well as the support! I am excited and can't wait to test this baby out!!

sounds about right, powertune quoted me for 6266 jb $1080

And that would be without surge slots which is about 200 more

ported cover and divided rear is more expensive

Finally got my 6466 .82 twin scroll running on a RB25/30 - beautiful response down low and its well on boost by 4000 rpm if not earlier,

Currently making 308rwkw at 13psi - low boost as the engine is still being run in.

That's good to hear! What's the maximum psi you plan on running on pump gas with that 6466?

Also, can you please do me a personal favor and measure the exterior diameter/width of your housings? I'm just worried I may not be able to fit it in my engine bay as my current setup is already a tight fit. Here's what my engine bay looks like:

I'm still debating whether to go with 6262, 6266 or 6466 as I'm planning to run this on 98 octane pump gas no more. I was told by a vendor the spool difference between a 6266 and a 6466 is almost negligible.

wow 86 pages now? this thread is popular!.

got some results from my build for yaz.

431 hp atw @ 16psi on the little 6262 t4 t/s .84 on pump with plenty more left in it. will update the dyno charts section with my dyno sheet when I can be f*kt, or after I go back for the second tune.

Well, curiosity got the better of me after I encountered an issue with my 6466. I removed the unit, removed the drain and inlet oil restrict or and had a peek inside. Seems the entire rotating assembly is shifting forwards and backwards inside of the cartridge housing, almost as is there is a retaining clip missing. So on the blower I get, and it seems they don't really seem too keen on warranting it as I removed the restrictor. The fcuk? I wasn't born yesterday! I'll. upload a vid of it soon. I hope precision comes to the party on this one, same goes for PT.

[SilverECR33]

I know stupid question but did you secure the retaining nut before you removed the restrictor? if you havnt, there goes your warranty, and that's probably what they think you may have done on the phone.

[33GTRV]

Yeah. I'm pretty savvy on mechanical stuff. I may have nailed it. Ill post a reply after I bench test it in the morning.

You fixed it?

[33GTRV]

Not just a pretty face baby.

[33GTRV]

Mate in town builds turbochargers for a living. Had a helping hand. See how we go mang.

[Piggaz]

Oh. That's awesome. Let me know tomorrow if its all good!

Then dyno, farken!

[33GTRV]

This man. He spent more time oogling and masturbating over the machine work on the thing than what it took to nut it out. He was like a downie with a rainbow crayon lol

Yeah I can measure it up for you PM me to remind me if I forget!

I had the same dilemma I spoke to precision directly and workshops in the US that dealt with them and they all pretty much said about 300-500rpm difference in each so I bit the bullet and went the bigger as I knew id always be curious if I didnt. I haven't looked back put it that way, although I have it in twin scroll on a 6 boost manifold to help it all along and its on a 3L

Should be mid 20s on pump and 30+psi on E85 for the get farrked boost setting

[donut_kng]

the 6466 is much bigger than a 3540 .7 front if that helps

pretty sure they are pretty much identical front cover size..

[G37Sam]

Thanks for your feedback Donut_king! It looks like I'll be going with a 6266. The 6466 seems like it would require a lot of boost to come alive and that is no fun mated when it comes to pump gas.

ill make 500+ on pump gas and 24 psi with unreal response.. something to think about. nothing wrong with the 6262 BB .84 option in my book.
