Precision Billet Turbos

[donut_kng]

hey everyone just wondering if anyone has a graph with a 64-66 on a rb26. . just wanna know proven figure without e85 just bp 98 pump.

thanks

Will be putting one of these on a 25/30 shortly - might give a vague idea.

i have seen dyno sheets floating around which are probably in this post somewhere anyway - which show the difference in the response between, 6266, 6466,6766 being about 500rpm on a 3.4L ...

I have even emailed precision directly who have confirmed that it would be about 300-500rpm on a 3L

Thanks. Have seen it but not sure on that one. I think the 6262 is the one.

ok kool keep me posted, il be ordering the 64-66 soon just looking for a good r32 gtr shell to put my engine in:)

Yeah just give it a ago they are pretty interchangable apparently.

I went for the 6466 as I figure if worst case it was 600-700 difference in response from the 62-64 - something i doubt im really going to notice when its on an engine which will snap the rpm needle within a matter of seconds anyway - which is worth it considering the top end gains!

Ive been guarenteed 500kw atw out of the setup i have on e85, so i imagine 400 isnt out of the question

[rbjunkie]

Is anyone running a 6266? How much lag are we talking about between the 6262 and the 6266? Can't decide on what to go for. If the RPM difference is negligble i'd be more inclined to go with the 6266 for the potential to make more power at a later date. (Both turbos with 0.84 Twin scroll)

Looking to make 400kw on a RB26 with all the basic mods. Will a 6262 make that power on 98pump fuel (say no more than 25psi)? I've seen that SimonR32 made 420 but that was on flexfuel.

I actually made 450kw and trust me there is plenty more in it but I ran out of fuel pump.

I wouldnt be suprised to see another 30-40kw if I ran 25psi but as you said that is on e85.

6262 is a nice balance for decent power and not too much lag. I was tossing up between it and the 6266 and went the smaller. I think I made the right decision

you would think that the difference would be minimal between the 6262 and 6266 but that depends on the rest of the specs...

anyone know the difference between exducer/inducer on the 2?

[Frosty]

this may help tho

comparision between the 6266, 6466 and 6766 on a 2jz tho

[rbjunkie]

Interesting... I'm leaning towards the 6262 to be honest... If its capable of making 400-450+ with good response then I think thats what I'm after. Thanks for the graph mate.

[Frosty]

no probs....i dont think there will be too much difference to be honest but i cant find the wheel sizes for the 6266

6262 is as below tho

Compressor-

Wheel Inducer: 62mm

Wheel Exducer: 82mm

Turbine Wheel -

Wheel Inducer: 72mm

Wheel Exducer: 62mm

i think i did read that the exducer of the 66 was slightly bigger but dont quote me

[rbjunkie]

PTE 6466 - for anyone looking at this turbo.

Compressor Wheel 2.535" (64.39mm) inducer / 3.410" (86.61mm) exducer

Turbine Wheel 2.920" (74.17mm) inducer / 2.600" (66.00mm) exduce

HKS T04Z:

Compressor Wheel:

T04R/T04Z, Inducer 66.7mm, Exducer 84mm.

Turbine:

T04 P trim, Inducer 74.2mm, Exducer 64.6mm

Garrett GT3540R/GT3582R/GT35R:

Compressor Wheel:

56 trim GT40, Inducer 61.2mm, Exducer 82mm.

Turbine:

84 trim GT35, Inducer 68mm, Exducer 62mm,

for comparison..

Alot of guys are running the 6466 in favour of the 6266 in the states and report no change in spool/response but more power up top.. Would like to see some results on RB26 though.

I'm gonna go the 6262. If my motor was built i'd be more inclined to go something bigger but I think the 6262 is what would suit my setup without going stupid or shit to drive on the street

So how do people reckon a PT6466 would compare with a Garrett T04Z in overall performance? Would you be able to use the Precision in the Garrett's place and expect to make similar (or better) power on pump gas on a suitably built engine?

6466 only comes in ball bearing tho which is all good but cant justify the extra cash for it

i dont think you can go wrong the PTE to be honest

Should make plenty more power without being too much laggier from what I have seen

[Lithium]

Thats interesting, I'd have hoped for it to be at least as responsive!

Well my 6262 is better than my old T04Z but not the miracle that some would lead you to believe. The 6466 is a fair wack bigger (195hp rated), I doubt you would be getting that for nothing

[rbjunkie]

From what i've read i'd say the 6466 would be about 500-800rpm later than the 6262?
