Turbo manifold - Anyone know what make?!

22nd July 2013, 23:47

any info is appreciated

23rd July 2013, 00:27

Looks like a dp eng one, but I've never seen one in (stainless?) Before so can't say 100%

23rd July 2013, 00:45

Nothing like a DP one.

And DP ones do come in stainless. DP external wastegate port is to the side from the collector.

23rd July 2013, 10:25

Yea its not DP.

It looks custom & I'm not sure if I should run it or not.

Its cheap at around £200 anyone think its worth a shot, saves forking out £550

only concern would be wastegate position.
it will by the look of design be very close to radiator

23rd July 2013, 21:41

ps may be camera angle but main flange looks warped

23rd July 2013, 23:21

Looking at it now i remember the manifold it took it around 6 months to sell on the owners club, ill stick with the stainless tubular ones that rickyp does just gotta save £550 now

Is this manifold on ebay atm ? Seen one which looks familiar and its up for £260 haha

Yeah its on ebay at 260 but I could get it for less

If I was you I'd leave it where it is, doesn't say what metal it is or the grade.

Welds don't look all that great and the wastegate is in a stupid position.

24th July 2013, 13:31

Looks like mild steel sprayed in silver. Unlikely to be stainless or else it wouldn't be sprayed imo. Might just be the camera flash / poor photos - hard to see.

The wastegate is actually not in a bad place - right off the collector. It's at 90 degrees to the collector flow too, which is technically better than the DP one which reverses the flow for the wastegate but it's really of no consequence in real life.

With a clean up, that's probably a usable manifold. Certainly better than the cast / chopped examples you normally see on budget turbo builds

The welds are hard to see but don't look "great" but don't look too shoddy either. The bottom line is will it work? Sure. Does it look ok? Probably (that's down to your opinion). Cost Vs looks, it's not a bad choice imo, but it's your money at the end of the day.

How close would this sit to the slam panel/rad surely it would be tight for a wastegate ?

And where the runners connect to the connector the welds look minimal unlike the dp manis where they build them up a far bit.

At the end of the day its not the worst but not the best

Yeah those welds need a good looking at. I don't think with a wastegate in place it would sit much/any further forward than when the turbo is in place. And a lot of people move the rad/intercooler forward when running anything bigger than a t25 anyway to make room for the compressor housing. I think it would be ok

24th July 2013, 15:18

Not sure if I should have it.

Yes I could get it ceramic coated.

I would not want to run a wastegate because my Gt28rs has it internally and I don't want to buy a new exhaust housing... Or a wastegate for that matter

Ross if u were me would u buy it? The engine should be running 250-300whp

So you will be running high boost ? Would recommend getting rid of the internal wastegate, just take the turbo somewhere who can weld. And block it off. As the external wastegates are far better at holding boost.

Sure ross will say the same

24th July 2013, 16:03

300atw on an internally gated gt2860rs? Not going to happen tbh. 300atw on a 2860rs is a big ask full stop, and you'll be running it WAY outside of it's efficiency island.

The internal wastegates really struggle to hold boost at higher boost levels so although you don't want to go external, you may find you need to to achieve those power levels.

If I were you, i'd be looking at a different turbo for 300atw. The 2860 will do your 250atw no problem, but at 300, it's really going to struggle.

24th July 2013, 16:34

There is no power target ill just get what I end up with

If running it external will make it hold boost better then I'll sort an external wastegate

So, all I'll need is to have the welds strengthened up and make sure its all fine, external gate. I'll either heatwrap it or have it ceramic coated.

I like the idea of the zirotec coating you have ross but it would cost as much a the manifold itself!

Jack is it you with my old 2860? I forget who had it. Was a strong turbo that to be fair. If it is that one it wont need welding as I had it done. Maybe it wasn't you if you're talking about internally gated... My bad.

Welds might be ok - worth getting a fab shop to inspect them properly like tho. No harm in them taking a look for a packet of biscuits and a cuppa etc.

Zircotec is awesome stuff but I regret getting white the first time round was a mare to keep clean. The black I have now is much more functional if slightly less efficient. Heatwrap is fine if not as pretty of course...

When you buy a wastegate, don't skimp on price - the turbosmart or tial ones are good - you dont want the same problems as internal because you saved a few quid on the wastegate. That'd suck

24th July 2013, 18:45

Fair enough. Gotta see if I can afford the manifold first off haha

But okay yes if you think it should be ok I'll take ur word for it

You sold the 2860 to jamie ollis, I was after it but he had it before me, think I text u when I was in france last may.

Right a small issue.

Offered up the manifold to the head. all looked well.

untill i offered up the turbo to the manifold..

The turbo fouls the block by a good few mm, which is annoying as i was told it would fit directly.

the wastegate flange is also very close to the housing.

Here is my theory, have a new flange built at this angle which would bolt straight through as a spacer?

At the same time have the wastegate flange cut off and the hole obviously filled in, and have the wastegate moved over to where they are on the DP manifolds

Thoughts guys?

30th July 2013, 22:03

If you are blocking off the waste gate then just alter the position of the flange on the manifold with a pie cut and re weld it on. No need for a spacer.

30th July 2013, 22:09

Me I'd be tempted to spacer it out with a few manifold gaskets; or as Bedford says, just the flage off and adjust the angle. Depending how handy you are with a welder.

What is a pie cut? or was that a typo?

I wont be doing the welding because.. i cant weld haha.

but i know a few good fab places around here that could cater for my needs.

it cant be spaced out from the head because if i did that i would be fouling the radiator with the manifold i think

30th July 2013, 22:30

A pie cut is the cut in the shape of a piece of pie. like this.

30th July 2013, 22:32

Gotcha, so cut the flange for the turbo off straight and then pie cut another smaller piece to level off the angle, i dont think it needs to be a 90 degree angle to the head but i suppose it cant really hurt.

i cant imagine how it would fit if the standard actuator was staying there as that is on the side that touches the block!

30th July 2013, 22:37

like this mate just remove and re weld.

30th July 2013, 22:41

Genius! im technically an engineer.. how did i not see that.

Will keep that picture to show the welder what needs doing. thanks bud!

plus it means the hole that needs patching for the wastegate isnt going to be so big

I would personally patch it before the cut then you don't have a start and finish of the weld on the flange so you don't have a weak spot. I'm not sure on flow also I cant see it being a problem because the opening will be slightly larger. But best waiting for some one like Ross or Blackie to comment if it would be ok flow wise.

that was what i was a little concerned about was the flow with changing the angle the way i wanted to do it was totally reversing the angle of which the air hits the turbos turbine so-to-speak

but the way you have described it seems to keep the same angle for the air and there is no drastic change in direction, so should create maximum flow

30th July 2013, 22:52

Flow won't be a problem - if anything you're coming further up the collector. My only "reservation" might be you'd be impeding the collectors function somewhat and may have slightly uneven flow into the turbo but in all honesty I don't think it would matter two hoots - you'd be staggered how forgiving turbo manifolds are.

Have you thought about mounting the turbo the other way round? Turbine side towards the gearbox. Does that give you more room?

i was thinking after i got in the house and washed off that i can swivel the turbine around anyway to have the inlet side of the turbo facing which ever way i like by loosening off the bolts.

ill have another play tomorrow and get back to you all but i doubt it will help much if at all.

another question while you are all here, how do i know what size wastegate i need. and other than turbosmart and TiAL are there any other recommended ones?

30th July 2013, 23:17

It looks like a 38mm one which is a standard size. Next up is 44mm and I'm pretty sure it's not that. Just measure the internal size.

Right gotcha, does the wastegate size matter, you was talking about holding pressure with the standard one.

like, what exactly is the difference between running a 38mm and a 44mm on exactly the same setup.

is it just noise or is there a specific reason for running said size.

finally. i have two options. 1 screamer pipe or 2. run the wastegate back into the downpipe.

i know the screamer pipes can be loud but are they unbearably loud or are they worth the street cred

31st July 2013, 00:03

The larger wastegate can flow more exhaust and prevent boost spikes. Bigger isn't always better and it doesn't follow that more power requires a larger wastegate.

Screamers are fun on the road but you'll never realistically meet noise regs on track days etc. they can also get irritating. I ran one for 3 years but now plumb back into my downpipe for several reasons - noise reduction mostly.

31st July 2013, 00:56

Chances are ill run a screamer pipe mostly because it means my downpipe dosnt need adjusting, but if it gets annoying ill have it plumbed back into the exhaust system, im all about keeping it quiet and looking OEM anyway so if its obviously noisy it will annoy me
