Precision Billet Turbos

[Roy]

Interesting comparison. It appears the -5s may have its measure when you factor in they ramp a tad sooner and with E85 may be able to get the ignition wound in sooner ? Real curious to know if they drive as per the textbooks with the twins offering a little more transient response ...any torque graphs?

[brad 110]

Has anyone yet run a 6466 on e85 and made 500 plus rwkw here? Cheers brad

[PJ.]

Brad, they make that at all four on a GT-R without a doubt

[Roy]

lol its not definite yet, but I have the invoice for a 55

58 .64

was going to pay it this week but funding fell short will need to wait a few more weeks maybe

I cant find any results with this turbo. It looks about the right size for my YB Cosworth (cruiser/street car) but still thinking an FP71HTA.

Do the internal gate setups work well...all the results i am googling are external setups. The R34 GTT seemed to be external for its 350rwkws so perhaps a 5130 is all i need for a grunty 280-300rwkws...happy to run up to 26psi

Yes it was external 44mm plumbed in.

Will be tuning sr20 with 5558 external this week or next. Just running motor in

thats more or less what I'm chasing but isn't the 5180 an old t3t4 based dinosaur?

yavuz at unigroup seems to have talked me out of the 5558 and back onto a simple 20g. Just as well I ran out of money before I hit the invoice

Really? Why did 5 if his customers just buy 5 precision turbo's but he tell u not too? Weird

[Roy]

20Gs make power at 19psi...Precision turbos seem to like over 24psi so if you don't have s built engine?!?!

[Lithium]

It seems they don't NEED the extra boost, but if you can - they reward you

[GTScotT]

I have been building though, Roy. A very basic setup but I wont be affraid to throw 25psi at it if I have to. Forged slugs, stock rods, race bearings, studs, springs, retainers, cams. Most of the work is done just need to get my crank crack tested and the springs put in the head.

It was Mick who did the asking for me on his recent trip there. Mick let him know about the type of setup im building and projected output and drivability, the verdict was that the 5558 isnt going to delivery the type of performance I want. I am envisioning it will be more like a 3076R, which I drove an SR w3076R on the weekend and it sucked HARD.

Ive sent off to see if I can get a PT 5130 for similar money to the 5558........ If I can then I think its a winner. PT market it as a replacement for an actual 3071R, meant to out perform in every way. See what the price is before I get too amped.

[Roy]

Powertune sell the 5130 for something like $1300. Its basically what I think I have decided is the go for my 2L 4cylinder...just need to do some more homework regarding internal vs external wastegate and flange connections and stack it up against the 71HTA with Cossie rear housing

[GTScotT]

WHOA hang on, Ive just realised something rather important. PT is advertising that item is a 56.5mm turbine.. Now normally they advertise the exducer size but I am thinking this is the turbine inducer. AKA a cropped GT30 turbine ala HKS 2835 spec.

A normal GT30 turbine has an inducer of 60mm and an exducer of 54.98.

However, the HKS spec 2835R has a 56.5mm inducer turbine.. The cropped one.

To back this up the internal gate housing is just a run of the mill GT28 spec thing.

AFAIK that is BAD news for us pissy 2L boys. Thoughts there Roy?

All the ones i have done have made big power on 22psi. Havent needed to go bigger boost as of yet

I am aware of 1 result on an ethanol powered RB25, what arent you telling us Jezzabelle?

[Weapon]

I confirm that!

Pretty sure u know about my GTR's results too

Another rb25 i finished made 301kw 16psi with a 5557 last week. On 98. With a microtech thats wandering majorly at high rpm. Stoopid ecu's

[GTScotT]

lol oh i know your GTR, i more meant the 5558 sized items.

waiting for your SR result

[N1GTR]

i no man, ill work it out one day, got a new exhuast coming and a new intake setup. So ill try that out, and c how it goes. If nothing improves ill just drive it as it is, till Stevo comes up with the goods on the bits and peaces to make her a lil bigger on the bottom end if you no what i mean, than prob throw the -5s in the bin lol

im very interested to c how this turns out but

Lets put it this way; you'll be having a new bottom end quite soon. The engine for testing is waiting on one part before assembly, and that part is being picked up at the end of this week and sent...

[N1GTR]

order 2 Paul

^^^This man, he knows.

Twin high mounts. Thats how you do it

[33GTRV]

Kinoath lol. I wish! Should be an interesting comparo between mine and pauls. Pauls has a mega dollar head and nismo collector, ive gone the budget route with a quick port job at home and the standard collector. Cant wait!
