Extreme Turbo Manifolds Or 6boost

[mico]

6boost, kyles manifolds are a work of art and he is a champ.

[dangerman4]

i chose a ETM when i highmounted my 35. it was perfect in every way.

[GTR1993]

I bought from kyle before he was even doing it as a full time job, i go there because he is a nice guy. I mean what else could you want.

[MBS206]

I use ETM.

One he's local to me.

Two, he's always looked after me, and never bullshits.

Thirdly, I currently do have a 6BOOST manifold on the car, and the welds from ETM are so much nicer. As Kyle tends to finish you get "holes" in the welding... Not an actual hole, but a weak point... ETM manifolds, you don't.

where is a pic of this new ETM 100 series design which stops boost creep? would be interested to see, however the website seems a little light on detail

[2rismo]

My ETM manifold is the shit and i could not be happier with it.

[GTR--J]

Can you ETM guys post some pics of your manifolds and inside the collectors, I would really appreciate it. Both the manifolds look good but it's nice to hear feedback from buyers.

[Gts-t]

Yeah the new 100 series sound good, id like some more details too though he probably doesnt want to give them away Might be just the thing for the 26/30

I don't think the new design would be rocket science. A flick through Maxiumum Boost will show you having a wastegate come off the collector at 90 degrees to high speed gas flow is one of the poorer ways of effective wastegating. Simply any shallower angle would be an improvement. Hence why when I ordered my 6Boost manifold (before I bought the Full-Race item) - I requested it be made without any wastegate provision - so that I could customise the wastegate position and angle.

I dream about your Full Race manifold......

Haha.....6Boost and no doubt ETM are good local products too....

Here's a post I made in my build thread ages ago.

Picked up the new manifold and modified exhaust housing today. Both the manifold and exhaust housing have been coated with the latter being modified to accept the 50mm Turbosmart Pro Gate. They look sensational. The collector design, the quality of the welding and the coating are all great. Leigh from Extreme Turbo Manifolds does exceptional work! Couldn't be happier!!!

Completed assembly:

Collector:

Exhaust housing modification:

If it has this plate, it rocks!

Beat that!

Freshly coated:

yeh...best way to control boost...straight off the exhaust housing like 2rismos pic displays...i did the same mod to my road car with the standard cast manifold and again on our race car with kyles manifold. Fixes boost creep everytime! Some people question if it has an impact on response because your disrupting the flow in the housing, but having had both setups (off manifold collector and exhaust housing) several times, there is no noticeable difference on track.

Both make very good parts.

Neither of them invented the merged collector.

I was making merged collector manifolds and merged collector split pulse manifolds 10 years ago and I didn't invent the merged collector either.

I have seen pics of turbo setups from back in the 70's with merged collector manifolds.

I am yet to see either of them do a true split pulse manifold. That’s not to say they are not making them I just haven’t seen one from them yet.

By true split pulse manifold I mean all exhaust gasses from opposing cylinders kept separate all the way to the turbine and wastegate, or two wastegates used.

If they don't make them yet ask them too. They both have the ability.

[DRIFTER]

my 6boost manifold is a "true split pulse manifold", same as the pic in post number 8 but with two wastegate outlets.

Both ETM and 6Boost do true split pulse manifolds.

Has anyone used one of their single low mount manifolds? interested to see how they look...

this is my 6 boost lowmount manifold, i just managed to mount the gt35 with minor mods to the engine mount on my 33

the only problem that i noticed was that the manifold lost the blackness it has when first bought and it is now a greyish colour

[bbe]

how much do both of these manifolds retail for ?

the best manifold i have ever seen in my life is of a r31gtsr only 400 made lobster style my mate has 1 it is a piece of ART Marky at E.T wanted to make them but after playing with it recons the collector is just not possible.

Sounds far superior to any 6boost and other no name manifolds i have ever heard !

[bozodos]

R31House do a very nice looking manifold in the style of the GTS-R one

[Beer Baron]

honestly 6boost and ETM are probably the 2 best known dedicated manifold builders in aus and both make great product. I have more first hand experience with 6 boost manifolds but I don't have anything bad to say about ETMs ones either. call them both and see which one you like the sound of most. or maybe just flip a coin. you will get a good result out of either one.
