^^^^ thats how i have been told it should have been welded in. My set up is as it came from ETM

Yea i know i was getting told that until the guy tuning my car showed me 3 other GTR's in the shop that had just been tuned. 2 with T04z's and a then one with a GT3582 same as mine running 6 boost ma

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

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......

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.

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:

If it has this plate, it rocks!

Beat that!

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.

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

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 !

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.

      Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy

      Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p

      @KinkstaahKrinkle paint the "silver" alloy, not the red filter frame Engine bay heat won't be a issue worth worrying about as the silver alloy blocks it off on 3 sides, as for the top, the bonnet seals most of it and the big OEM CAI intake snorkel is still fitted in its original position  I will head into Clark's Rubber when I have some time to grab some pinch weld to tidy up the alloy after I paint it As for performance, I honestly wasn't expecting any, the only reason I got it is because the intake noise sounds cool to my old ears when I'm feeding it the beans Sometimes it's the silly things you do in in life that gives the most fun, and I do love anything that makes cool car noises In other news: I survived 4 nights at sea with Jackie not throwing me over board, holidays are continuing now as we are currently chilling at the Beachcomber in Toukley, after taking the coast roads from Sydney in the MX5, top down all the way, Toukley is where I spent a good deal of my youth holidaying during the summer months, there's lots of reminiscing going on,  and lots of beaches and old houses to visit Next on the list is to head to Batemans Bay for a few days, but we will take the Commodore out to stretch its legs, then Commodore hasn't really moved for months

      There’s probably people who’d like to do it and then when it comes to putting their hands in their pockets they’ll all disappear into the shadows

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      interesting....sounds like the later trans has software differences (or AM vs JDM). If I wasn't going down the tuning route it would be worth looking into retrofitting a new computer to the old box.
