Thread: Tubular Manifold Build

Started building the turbo manifold for the VET.

Stainless Steel sch10 weld El's, T3, and BOV flange. Mild Steel head flange, SS ones where way too expensive.


Started looking for the best location for this. Moving it as far right as possible so that the down pipe clears the A/C.





I'm using a RWD DET manifold flange. First the studs didn't let the flange through.


Used a 1/2" drill bit


Fits perfectly


With my luck the flange didn't come threaded, had to get bolts and weld them on. SS bolts are not cheap .



Don't mind my crappy looking welds. I'm still learning and since there is not much room to play with, the welds got a little flooded. I plan on grinding them down a bit.



Next fun part is getting the exhaust flange to align with the runners. VE runners sit a lot higher. FWD flanges started accounting for this, but it doesn't look like RWD ones did.
This is a huge restriction.



Traced them... that's a ton of metal to remove


I had to taper them, otherwise the SCH10 pipes would be too small to fit right.


Manifold side:


Head side:


Much better


Tomorrow will start cutting the sch10 weld el's and mocking everything up.

GO Vadim GO!!!!

woot! looking good! keep going! I've started my port matching yesterday too for my VET manifold.

Hey we have maybe 20 mild and at least 2 SS flanges on the shelf @ work , I dont remember if they are all DET or VE ...I will look if you like , never mind my cost( I have dist. pricing at JGS ) is about the same as Mazworks wants for theirs , anywhays this lookslike a fun project , I am jigging up a GTI-R manifold as we speak to see if I can build a stock location manifold with a eternal WG .

And as for parts , you can get Merge collectors and all kinds of bends from a few good places ...

Lookin Good!

Vadim email protech I think they have a few VE flanges in stock. They are thicker than the one your using right now and look 100% better.

Good work soo far. All I can say is good luck man especially with a mig welder. I gave it a shot with doing mine and said screw it, I couldnt even get it to tack right with that material so I could have it tig welded by someone else. It was frustrating and a waste of time and money for me.

Granted the mig i was using wasnt very good but still. I thought i would be able to at least tack it up. Nope.

you will feel the power now!!

The Mazworx head flange is the best for the price you pay, saves alot of time and can be used on VE and Non VE head without modification.

Can't wait to see the end result!!!

lol I have that same micrometer to check rotors =p gl with the mani!
