Turbo

were did you get that flange from atchi cheapest i was quoted for a laser cut ss flange was £70 for 1 or £25 if i ordered 10

cheers steve

Hi Steve,

It is my local laser cut place.
They will cut from 8mm Stainless steel for that price.
If you want some, let me know. I made one for Dominator before.

Cheers
Atchi

yea will do mate i might have one next week i just bought a load of stuff off of ebay some will be for sale soon turbo stuff so pm if your intrested

steve

p.s why not buy a collector and make a equal lengh mani or is there no space in the mini

Hi Steve,

Yeah, no space what so ever!

You can see from this photo here.


I got TD04 and hoping to make one log style manifold to fit may be above gearbox.
I got an engine block ready for forced setup with Vitara pistons, o-ringed at Jerry's house.

What port size do you want with it 35mm or bigger?
If you want in mild steel, let me know. I got 1 spare.. oh I got 1 stainless spare also.

Cheers

port size im just after stock im gonna guess thats 35mm i already got a td04 flange off of ebay in ss were did you get your pipeing/what size you going for do you have any td04 downpipe flanges aswell javascript:emoticonp('')

cheers steve

Hi Steve,

I do all of my CAD work myself and get it laser cut.
I have down pipe flange already but I made it too big so I might have to re-draw it again.
I'm not sure where to fit my turbo yet so I will make sealed log complete then I cut where I want to fit by cutting and welding a flange to it to the manifold.

I will check what bore I got as I made bore bigger to fit tube into it before.

hi all
what thicknes of steal would u use for manifold pipeing and what size would u make the log part of the manifold as well

cheers dan

Hi,

It is about 6mm thickness tube for a turbo manifold.
You have to remember any thinner than that, you will be getting cracks.
This is pm from DMWDave when I contacted him before!

Hi,
I have seen a log style manifold mounting turbo over gearbox,
I normally follow rule of thumb using whatever size exhaust port is for the tubeing size.But with a log style as each cylinder runner joins the main pipe it should step up in diameter,so you may start with a 11/4" at the water pump end but end up with a 13/4" at the turbo flange end,if if you dont step up then all your exhaust gas has to escape through a 11/4" pipe !!which may be restrictive.Step up from cylinder 3 to 11/2" then cyl 4 13/4",1&2 being 11/4".

If you make the manifold out of that thin wall exhaust tubeing it will crack,go to a a thickwall(4mm)either in mild steel or better still stainless,most places call them weldels,a good metal fabrication supplier will have them,they are 90 degree preformed bends available in 1/4" step up sizes.

This is the site you can buy it from .

Std wt will be fine for mild steel.
I haven't tried to make one with Stainless steel type.

Cheers

wow a great site atchi just for anyone who is going to ask look below this is why i dident go ahaed witht the manifolds i couldent find the bends cheap enought it was like £12 and £14 a bend which when you think about 5 or 6 depending on design plus laser cutting plus time soon amounts up

11/4" diameter of pipe
sch 10 gauge of pipe
90 degrees the bend

cheers steve

hi

i like that site very helpfull info thanks all yet again i am going to start makin 1 will post pictures so u can see how i am getin on . there is 1 more thing what size is the log part of the manifold



funny enf this is swifty norfolk manifod i wanna make some thing like this

[url][/url]http://i129.photobucket.com/albums/p207/swiftygti/31102008097.jpg

dident that one keep cracking i thought he bought a turbinetech one

steve

looks like it was made with threaded gas pipe

atchi
couldnt you just use a tapered plenum type mani rather then steping up the tube size before every ex port
it would be so simple to make, of course it wouldnt have the best airflow in the world, but it would be alot better than the one in the pic above and you could mount the turbo whichever way round you want

gary

i am not sure if it did steve or not that is why i am skin you guys if u no any info .....

how about some thing like this was thinkin about tackin it up and geting some 1 to weld it all up for me
