Hey,

got a highflow vl turb with t3 or t4 cartridge and some kind of modified rear housing.

i ran into dramas dummy fitting. ill let pictures explain.

as you can see straight up we have an issue with the dump pipe off on an angle due to the vl turbo mounted horizontal instead of vertical.

now im wondering without making a new dump or modifying the dump can i get it to fit properly.

as you can see if i hold it like so all the oil / water lines will line up, but if i modify the dump and bolt it straight up the oil return is horizontal not vertical.

any ideas... its asif i need to make some kind of t3-t3 90deg piece or if a rb30 turbo manifold would fit im not sure on stud pattern.

any suggestions would be kool, otherwise ill whack the stocker back on.

thanks,

dave

sorry i read it wrong...

have u tried rotating the exhaust housing?

No matter how u rotate the exhaust housing the dump will still stay on the same angle. might need to fabricate a new dump to suit mate.

for the oil feed it should be vertical so just rotate the 2 housings so that you get it in that position then get some braided oil and water lines, you then may have to rotate the turbine housing so you can get your pipe on your snail.

The most costly will be getting a dump pipe made to suit your turbo. probably around $400-$600 from your common exhaust shop.

im gona mod the dump myself. but ill try rotating it all. i knew you could rotate it but i was looking at the dump all the time going wtf !!!. but ill see how i go and then hopefully be able to mod the dump.

as i said this came off a R33 so i have no idea how the dump pipe worked out?

it would have had a custom manifold, possibly a high mount :) thats why the dumps like that

custom maybe, highmount no the dump would then be pointing at the bonnet. if a rb30 turbo manifold fits a rb25 thats what it would of been mounted on.

thanks for help, its on now, and im gona mod the dump on the weekend. factory lines fit, just needed the braided oil line. :down: the first time the rear housing didnt spin, but a whack with a rubber mallet fixed that. :)

if u put a peace inbetween the ex housing and the mani, the turbo would most likly hit the engine mounts when u put it in a car. Mod the dump, should b pritty easy, just cut the pipe off the flange, panel beat it to fit the right way and weld her up : D

if a rb30 turbo manifold fits a rb25 thats what it would of been mounted on.

nope. probs something like a hks cast low mount mani that has the flange facing down.

most important thing is to make sure the oil feed is at the top and drain is at the bottom, as close to vertical as possible

    • No chop chop of anything mate, it is what it is, plus, I don't want any air that isn't either going through the cooling stack or intake getting into the engine compartment increasing under bonnet pressure  Yeah, the Mazda Speed aftermarket intake above is less than ideal for multiple reasons, the requirement to remove the bumper every time you need to service the filter, and also smaller in diameter than the NC1 OEM one Weirdly, Mazda Speed is part of the Mazda motorsport division, "form over function" and $$$$$ for Mazda from unsuspecting punters I suspect  After some googling about them it seems they added no power, but do increase some induction noise Meh In other news, the electricians have been busy today at the house, and are back tomorrow finishing up all the security stuff and exterior lighting, they also added some lighting on the garage ceiling, which will come in handy when working in the garage when it's not freezing out there My Birdies raised garden bed also arrived today as well, which I'll put together and place tomorrow, it's a big tall Bessie, 74cm high, 92cm wide and 214cm long, this will come in handy as I am starting to get "stockpiles" of good soils from doing landscaping, some of the clean rock, namely the river stone, will go into the bottom of the bed for drainage, as well as the old Apricot tree that was out the back,  and when it's full, I'll grab another one, I will be growing enough veggies to keep me both busy as well as supplementing the shopping list I'm also awaiting another quote for a new Colourbond front fence, as the "1980 style cemented in rock edging" that was there and "fashionable at the time" looked arse, and my god, the amount of cement used to fix the rock was insane, it took 1.5 days for me to break out 12 meters of the stuff by hand, trim the bushes back to the fence line and dump it out the back of the joint to deal with at a later date,I will soon need a skip bin to tip it all Unfortunately they did alot of the cemented in rock around the joint, which I hate, so a few pallets of retaining wall blocks for around the front and back where the cemented in rock is will be required to bring it up to a standard, and look, that I will be happy with 12 meters worth of rock and cement Finished smashing the fence line and ready for a fence to be installed, yes, the lawns need some TLC and thickness, the previous owner trimmed the grass to the roots 😢, the TLC I can provide, and nature over time will do the rest And there's probably about another 40 meters worth of this landscaping abomination left to do around the front and back gardens, I'm guessing maybe 3 or 4 tons worth, tip fees for this will be a killer Meh, all in all I'm having fun and keeping busy, plus, it's good PT
    • If I drove to a typical petrol station, what would my choices of fuel be? 
    • Just cut the bottom of the guard out. It's no longer got a big duct, to a sealed box, or a restriction. It has all the cold air from outside. Also, that cai you showed looks terrible. Bends are NOT good for go gos!
    • Like I said, "black magic" LOL In the end,  it is what it is, and hopefully, what this here knuckle head has done is an improvement and not a hindrance Not that I actually notice any negatives now, or that I will get any seat of the pants benefits when all is said and done, but best practice says I shouldn't be pulling intake air from the hot engine bay  Famous last words: I cannot see it being any worse than what it is at the moment 🤔
    • If the gases flowing in those two tracts had the same properties, you could maybe use such broscience. But the exhaust has a different composition, different normal density, different actual density (because of different normal density, and mostly because of the massively higher temperature), and different viscosity (again because of much higher temperature). Consequently, all of the fluid dynamics parameters that matter, that you calculate from these inputs, such as the Reynolds number, friction factors (for wall friction) and so on, are all incomparable.
