    Hi Mount Manifold.

    Posted · Edited by FJ RB25

    I too have the same problem with room and not being able to buy something off the shelf, I purchased a merge collector from someone who manufactures them for a living.

    Thumbs up to making your own manifold to, something that not everyone can do.

    Not sure if you have done this yet but I have been told that you need to rack the whole manifold together first so you can have all the runners in the right spot.

    Let me know if you want the place where I got my merge collector from.

    A fella here in Perth told me the standard exhaust manifold fitted in his Ranna RB25 swap.

    Looks Like Garrett Slipped Another Gtx30 Variant In .

    Oh no way man you will be finished way before me.

    I have been gathering parts etc while dragging my ass ( not literally like a dog) getting shit done around the house, start my build next month.

    Have been buy parts when cash is available and thankfully I have majority of the exy stuff now so it is all my own labour to come.

    Nothing real flash really, not looking to join the 300 killa wasp class yet just after a good responsive daily that doesn't draw too much attention from the plod.

    Normal mods like forward facing Freddy manifold, high mount exhaust manifold with IWG gtx3076, looking at the .63 housing as well for response same as you,

    Ps 2000 Haltech with long loom and perhaps flex fuel so I can run E85 when I update the Std injectors and throttle body for now until the need for more speed oh and the cash allows lol

    I hear good things about Galvsport, talked to them a few times and always been helpful, I go through a mate Peter up at Gidgie motors up in the hills now though.

    Cheers and look forward to your end results

    Good on ya fjrb25, this is what being a car enthusiast is all about, having a go at all the jobs! It's all good and well having all the big name stuff -ie 6boost, but what do you get out of just bolting it on?

    a good manifold yes, but how many can say "yeah I made that From scratch"!

    not all of us are building 8sec cars, some of us are in it for the satisfaction of build our own cars.

    Hi Nick

    Ain't that the truth

    My car when completed will weigh between 1100 to 1200 kg and it's going to be a daily driver, not a drift or time attack car.

    Not looking to squeeze every last ounce of performance out of her but I still want to enjoy myself also.

    Can't knock a fella who wants to have a go hey.

    Once completed I'm going to get a steal plate cut out that says (home built) and weld in place on the first runner

    For me it's the satisfaction of making it myself as you say and once I obtain the correct skills I will be able to use them in the rest of the car.

    For you and I it's not just a case of buying a manifold as there isn't one that suits our build, always wanted to build a steam pipe manifold for my turbo diesel also so may give that a go sometime too.

    Cheers

    All good guys and thank you for the advice.

    I am going to build the manifold myself, CnC collectors can be purchased for a reasonable price as can the flanges.

    My build is unique as in as far as I know what I am doing hasn't been done with this engine before, therefore many things will be have to be custom made.

    At the end of the day if the manifold I make doesn't perform as well as a professionally made one there are benefits and downfalls

    I learn a new skill and can do other custom parts/ jobs

    If it works I save money

    If for some reason I balls it up and it doesn't work then at least I can send what I have off to a pro so they have a template to go by, and I have still learnt a skill.

    All up for me the upside out ways the down side.
