Single turbo build turbo recommendations

[colbycg]

Whats up all. I'm acquiring all the parts for a single turbo build and currently stuck on what turbo to run. I'm not power crazy and had my mind set on a pt5858 for daily drivability but after reading all the horror stories about precision and their reliability/customer service, I'm wondering what the other alternatives are out there that people have been using. Thanks!

[jaychen]

use anything you want.

lots of people also dont have a lot of failures with PTE turbos.

xona/garret are going to need water lines too.. keep that in mind.

bw airwerks comp housings are huge, so you need to keep that in mind.

monty had a 5858 first (i think) and now runs a 6062. made 700ish...

just get craig to build you a kit. run your 5858 and blow your shit up.

[olethalb]

Not to hijack but how do single turbos (general statement) drive compared to stock k04's for example?

[colbycg]

I already have a complete 034 kit and a few other bits. I don't think I'll build the engine at first but we'll see how it goes when I get into it . I do realize most people that have issues with PT are running the journal bearings not bb. Just trying to get some more opinions before I drop 1.5k on a single piece so it doesn't (literally) blow up in my face.

FWIW, a few years ago some guy came out of nowhere with a custom tube manifold single 5858, ran 10s, and disappeared.

I can't wait to see more of these tube manifold singles now that Craig has picked up the market.

single vs twin won't make the difference in the way your thinking, while there may be a small benefit of going single (less rotating mass, less friction etc) the spool difference of a properly sized turbo(example to match the k04's) would be negligible. the real benefit is the ability to run much larger turbos, easy of maintenance, and less expensive(initial cost is about the same depending on your fab skills and labor cost) down the road if you ever plan on going bigger or smaller(buying a single generic fit trubo vs custom made ones for the 2.7)

[olethalb]

Thanks blitz 👍🏻

[Bordom]

a 5858 has already gone 10's. you could start there if you know how to drive

oh yeah, montycarlo or whatever his name was.

broke a lot of shit getting there iirc.

This is exactly why I'm going single. The less times I have to pull the motor if something goes wrong the better. Jaychen and DieselElectric, are you referring to craig from WDR?

damn, thats unlucky.

shitty kit.

I think you may have misread, I don't mean it has blown up haha. I'm just looking for advice so I don't buy a shit turbo that does.

Nah this was a guy who came out of the blue with his build. Did all the shit himself, and did work. Destroyed a few clutches with NLS but still, did work lol.

His car weighed a bit on my decision to stick with twins. I'm not so sure that the 2.8 manifolds do a single justice, and I wasn't looking to spend tube manifold cash...

End of the day I got a fast car for small money when compared to some builds, and I still haven't maxed it out yet. (Limited currently by stock fuel lines/rails.)

Really, it's going to come down to end goal and what you want from the car. I don't mind pulling my engine and I'm not shooting for huge numbers. So keeping it close to original setup works for me.

yeah, it was montycarlo. in canada.

and OP.. i meant the 034 kit. its a piece of shit. so unlucky for buying that.

really? I heard the early ones had issues but the revised one has flex joints and doesn't crack like it used to? should I look into a different brand or a custom setup?

[jaychen]

have you actually bought the 034 kit yet?

[colbycg]

have you actually bought the 034 kit yet?

yes

[jaychen]

yes

i'd sell it and get something good built.

[jimmer009]

I don't mean to hijack the thread. But dieselelectric, you day 2.8 exhaust manifolds are the best for a single turbo. I plan on redoing my set up and centering the turbo behind the engine. Would you recommend a different set of manifolds???? Stock is only like 3/4 inch opening and in a twin set up they make great numbers. Thanks for helping me. I just want to get the best set this time around.

[jimmer009]

Sorry I was in a hurry to write that and I didn't really have time to proofread that till now.

But you say that 2.8 manifolds are not the best???

Is there a better option????

Don't get me wrong, I am purely speculating from what I've observed.

[blitz2190]

the best sized manifold will depend on the turbo, if your running a smaller turbo with plans on quick spool smaller runners are better(just not to small as to restrict the flow) but will have a limit on top end flow, how well the runners merge and flow of gas is also important. IF your going for top end power you'll want bigger runners but not so big that it hurts the velocity of the gas and you end up with extreme turbo lag. the 2.8 manifolds are popular because it cuts the cost down and is already made.

[jimmer009]

Well I trust your opinion diesel. And you're to blitz for that fact. But I plan on running the holset for now and some day stepping up to a big boy turbo when I build the bottom end. So I think 2.8 manifolds are perfect for what i need. Thanks guys. End of thread hijack, carry on

[aysix]

Precision has small housings, that's what your kit is built for. The turbo is the least of your worries. Get the 5858, if you think it's too small then take the 20 mins to swap it out with a bigger one and sell the old one.

The problem with this platform is when people over complicate things. Just send it.

[slow ride]

Turbonetics offers the same turbine housings and a 1 year no fault warranty. I use the same dual v band .82 housings on my corvette. Just another option

[colbycg]

I think I'll probably end up going with a 5858 .64 BB and hope both PT and 034 stand by their product if anything happens.

.82

[jibberjive]

Does anyone know if anyone has actually run the 3.0 manifolds in their single kit? It has divided, rather than log, manifolds. I posted a while back about it, and one person who had a build thread bought some, but I can't remember who.

[Nollywood]

European 3.0 V6 manifolds are larger than those of the 2.8 and North American 3.0 V6.

They need to be off an A4, though. The European A8 3.0 V6 used the same engine as the A4, same code (ASN) but had smaller runners, same size as North American A4 headers.

6062, .64, 2.8 heads/cams, stock valvetrain, H beam rods, e85. Rev it out to 7500. Based on Monty’s dyno sheets he had 30 PSI at 4k RPM and carried power to 7500. Making at least 700 wheel on his first tune with the 6062 on e85. That’s the best bang for your buck IMO.

monty had cnc heads from old mate british too.

I believe his fab shop is Fabless Manufacturing.
He's on Instagram, where there are some photos way back of the setup - if that's who we're referring to.
That was a white s4.

There was also the guy with the silver s4, which coincidentally was for sale either earlier this year/late last. I think he was looking for around $20k CAD.

[Trb1]

This is true. He also has an RS4 intake and TB too I believe. Wasn't it just intake side work with those heads? He did end up swapping over to 2.8 heads recently though. I don't know if the larger exhaust porting from a 2.7 head (vs smaller 2.8 ports) would have helped or hurt spool with the e85. Obviously would have helped at top end, but I can assume not by much with the .64 AR. I figure it was a lot for a little with those heads, as it can get with that power level. This is all just pure speculation as I don't know exactly how much work was done to the heads.

The 6062 BB just has a lot to offer with little to no compromise. Good power level, and you still retain a large power band. Especially if you rev up to 7500 which is perfectly doable on a stock valve train.

montycarlo is the silver s4: http://www.audizine.com/forum/showth...ingle-turbo-s4

isnt the 6062 quite a bit bigger than the 5858? I'm going for daily drivability not max hp, though I am obviously looking for as much as I can reasonably get. I want to be able to get into boost fairly low in the rev range and I feel like a 6262 or 6062 would be a little overkill. If I can go bigger and not sacrifice too much I might go that route. Also, from what I've read, doesnt the smaller housing spool faster? I've been told I should definitely go with the .64 over the .82?

What did you end up doing?
