Precision Billet Turbos

[levinboy]

While we're posting pics of manifolds

Damn you

Tempting very very tempting

Might have to sample your setup

[WHITER33GTS-T]

That's a really nice looking manifold.

Does it seem to work well running the single gate for a twin scroll?

I was told i would have boost control issues with how the wastegate was setup but I never had any problems. Im also running a 60mm gate

For $1200 its a pretty good thing

I just need to swap out my old Garrett T51r for something in the Precision range.....

[jet_r31]

I never did either..even with a 45mm gate..ran my spring pressure..16psi with no creep, however my mates

rb30 did creep, think he didn't get under 26ish psi with that small a gate..however from memory he went 60mm and then

had no probs

cheers

Pretty sure the powertune R34 did 700rwkw with a 7175, max power was at 6700rpm from what i remember?.

By the looks of those pics, the 6 bob looks like a better design than the full race, yes the full race looks fancy but so what it gets covered in heat wrap and a turbo.

Look at all the weird straight sections and small bends on the full race, in the 2nd pic look at the tight bend on cyl 6.

Did u measure the runners to c if they are tuned length Joey? It's hard to think they are with all those little bits and peaces of pipe and small bends.

[GTR_JOEY]

Na I didn't measure it mate, though I don't think there is "too much" difference between the runner length

I assume it would be harder to design and perfectly match everything on a manifold that runs two gates and is true twin scroll

I didn't heat wrap it either

Haha you know where I live

Ok just ran up Aarons R33 GTR with built motor and type B Poncams with -5 turbo's. Also has adjusted cam gears.

We ran it up on 98 as we were about to change to id2000's and eflex but unfortunately the adaptors were incorrect.

Here is the overlay with my 6262 stock motor stock cams

Didnt take long only got home and had a shower , lol

[DVS JEZ]

Haha. Of course not. Mobile photobucket then added to SAU.

Stoopid injector adaptors

[Piggaz]

Is that a full effort tune man?

[R31Nismoid]

Difference isn't as great are some are making out it would seem at least at those boost levels. Put E85 on the -5s and it would be quite close.

Interesting comparo indeed

[Nee-san]

need to see back to back E85 jez

[Deano 1]

That's awesome result for 98. Killing it

[DVS JEZ]

Is that a full effort tune man?

Unigroup tuned this 33 previously.

Will be tuned on E85 this week.

[Piggaz]

Comp ratio with the built engine?

Any head work?

[DVS JEZ]

Unsure of headwork or comp ratio. See if Aaron chimes in here if he knows.

[gtraaron]

No head work just the tybe b cams , not 100% sure on comp but would suggest close to std the engine was build when i bought it by boostworx in sa , i bought it from kris on sau who bought it from previous owner who had it build , although it only had 5k km in 4 years put on it ! ( it was just a hi octane rebuild kit done on it ) it was stock when i got it just the motor was done i did turbos , cams , etc , etc , etc , cant wait for e85 comparison oh and dont forget to get those addaptors Jez !

[Deano 1]

Which adaptor is it? The 10.5mm ones for the injectors to go into the rail?

Yeah Deano , Jez 's ones are metal ones they fit nice the plastic ones injectors came with are crap and didnt risk using them .
