Exhaust mani and gate options

[Taz]

What options are people running for a/m manifolds? are evo options a bolt on? Im running a td05 evo turbo on it, so im running a pipe over the manifold. By going a/m i wont have room to run that pipe, which means ill have to rotate the turbo to face down, so i imagine the easiest option if theres one available is to run a mani with a gate provision and weld up the internal turbo one? Is there a "off the shelf" manifold with gate provision that will fit that would do said job for me?

Can run the stock manifold n run the gate of the 02 housing

Bump - had a look at a few manifolds but most seem to run a max of around .6 to .7 AR. Got a 1.08 in the garage im tempted to throw on if i can find the right manifold at the right price..

I welded the internal W/G on my td06/25g, then added a 40mm ext. gate with some interesting pipework. Pics aren't the best, but if you need more details PM me/FB group and I'd be more than happy to help out.

When will that thing be bolted on to the car mate? Been too long....

 

[Benzo4gT]

Yeah man, I've not posted for a while. It's going great now, comes on not much different to stock like you said, and top end hammers.
I think with the 40mm Ext. gate and the Apexi AVC-R are a good combo to get it ramped up fast and the WG makes it feel like it has a bigger arse end high RPM.

No chrome or bling, just rust and unfinished stuff.

Thats awesome news that you finally have it happening. I never got to use it to its full potential due to the shitty wastegate setup it had.
How many PSI you got it running at?

 

[Benzo4gT]

14psi, I had it at 17psi for a while on stock ecu......went like hell!
​I haven't even tapped in to ECMLink, just so little time to tune.

 

[evo-gsr]

14 psi !? Its still asleep at that level...wind the cunt up on e85 !!

That wont work? Or am I missing something? ?

Yea I've seen a few like that, drill a hole out of the rear housing in the appropriate spot and weld a bit of pipe and flange to it, just has to be in the housing somewhere before the exhaust gas hits the wheel.

 

[BYBY5L]

The 02 sensor in the dump pipe yeah? Exhaust has already pushed past the ex. wheel though... dunno, sounds shit to me, about as good as welding a pipe on the stock cast exhaust mani for the sake of an external,

 

[evo-gsr]

Jamie....MAPerformance sell heaps of dump pipes /o2 housings with a provision for external gate. I have one of their dumps on my Evo.

Ahh, I see how it works, just checked em out, so the turbo exh housing is pretty much the same as a std one but with the internal w/g flap removed, I was imagining a v band exh single exit type thing
