Precision Billet Turbos

[Lithium]

Typically the 6266 has just been the same compressor as the 6262 but with a bigger turbine - I can't see why they would change that, but I don't know for sure.

love to see the dyno sheet after your done gl

[gdzlar1]

Thanks heaps man, keen to see what it makes lol

[gdzlar1]

Also Anthony at mattouk will be tuning the car

[G37Sam]

I would go with a larger turbine housing if I were you. I wouldn't restrict such an awesome setup with that 0.84

[gdzlar1]

I've already purchased it man and got it right beside me lol, I honestly got .84 because either way the 6466 makes power but I would like the response aswell at the same

Time

[gdzlar1]

Sorry forgot to mention it's got the t4 housing aswell

Exact same 6466 I put on my 25/30. Mines not really overly laggy, I couldn't imagine what the larger rear would be like though

what ecu?

So this turbo I have will be all sweet for a fully built 26?

[gdzlar1]

Will be running a haltech platinum pro..

Sure will. 101 motorsport have a 26 running twin 6263's lol 1300hp

[gdzlar1]

Lol sweet dude, let's see what she produces I hoping it gets the 500kw mark

[PJ.]

.84 housing will do 500kW on an RB all day, nothing wrong with the housing choice. I pushed > 630kW atw through mine before I started to see signs of a restriction.

[gdzlar1]

That's insane pj 630kw is serious power lol, Anthony at mattouk said I should be able to grab anywhere from 500-550kw with this setup so let's see how we go, I was told by joe at gas motorsports this turbos wil do

It with ease I was Goinf the 1.00 ar but I want some response as it's a t4 so .84 was good for me I think

[NXTIME]

I wouldn't go anywhere near Maatouk's with a Haltech...

[gdzlar1]

His a haltech specialist, his cars are all ran on haltech and microtech, he was tuning at my mates shop other day man, done a few great tunes actually I was happy with him

[NXTIME]

I wish you all the best. Just make sure he doesn't tune AFR's of 13:1 on 23psi... Oh, and then locks the Haltech.
