Precision Billet Turbos

[jet_r31]

not suprised, being auto...my 4294 with a .91 T6 housing wasn't any laggier than a 3540 1.06 on a RB30 single cammer really with a auto

only a split second was a 3540 better and then the 3540 got fiercely trodden on...

agreed that drag+auto = a totally different ball game when it comes to response. its got very little in common with response on a street or circuit car.

have had a 3076 on an old school 4 pot feel as responsive as a T25 SR with the right cam and stall combo. easy to do, just useless around a bend.

I had a 35r on a 6boost mani, I changed to a new 6boost mani and 7175, and it is more responsive In every way, makes more power earlier, power doesnt drop off, and builds boost on the tbrake significantly faster....

Must be moving on from older technology that did it...

Don't be stupid Paul, there are no compressor maps so they are rubbish.

Here's a clip armed with the 7175. Lost a bit of power with the changeover to C16 but there's more in reserve still...

[NYTSKY]

f**king awesome!

[SilverECR33]

Eagerly waiting results as this was the same path I wanted to go down! Built motor? Is the 6262 Gunna be pushed hard mate?

yea fully built 25/30, will be pushed hard eventually . Just dummy fitted the hot side tonight.

Looks good mate how long before it hits the dyno? Is it journal or ball bearing?

[Johnny]

great looking turbo, arent they. Would do very well on a 30, cant wait to see the results

Tossing up between a 6262, 6266 and 6466 on a stock capacity RB26... Looking for good response and 400-450rwkw on moderate boost 20-25psi

T4 0.82 divided rear... Want most of the boost all in by 4000rpm

Also is everyone just going journal bearing or running the ball bearing? I don't mind the extra cost if it's worth it

Well after Jez's result on his standard 26, it'll be hard to go past the 6262. He made 402 at just over 20 -21 psi IIRC.

[DVS JEZ]

Correct

[SimonR32]

Yeah I know... I want him to get some more videos up

[GTScotT]

I've seen some photos of the 66mm cea turbine next to their older stuff... I'd be highly tempted as the aero looks great.

Question in my mind is 62 vs 64 compressor in terms of lag. Id be tempted to just go a 6466 for the headroom, coz u know u will end up with a dirty 30 lol

Only vids i have is at the drags

When I was comparing my 6466 to a 6262 a few weeks ago, the angle on the blades looked a little different but also the gap between the blades on the intake were signicantly more of the 6466. Both were CEA's

[GTScotT]

Hmm thats indicating its more than just a change in trim, the 64mm comp must have a way bigger exducer than the 62mm so its more or less an entirely difference turbo.

Like comparing a 3076 and 3082 I guess. Same stuff, different application entirely.

A link to a page with comparison to old tech 65mm wheel (I think the 62mm turbine is same tech) and compared to new 66 CEA turbine:

FYI both 6262 and 6266 are rated as 700HP items. I'd be chasing that 66 CEA item, better tech is where its at.

Finally got the 5558 in today, can I use any 3" v-band flange off ebay (exhaust/dump side), and what oil line/fitting did you guys use - do I just go to Pirtek/Enzed or get an ebay jobbie - re: Kando lines fit? I am not sure if you just connect the oil line to part way in the existing line or get rid of existing and new one straight to block? thanks
