I think he means like this collector on the manifold I have just made

Nice workmanship for an equal length Datsgold.
Due to the firing order 1-3-4-2 using a divider
its best to pair up 1-4 and 2-3 as Simon says.

Looks just like the one on page 7, great work. Looks like you've spread the two middle runners a bit to avoid fouling the mounts.

DJF280 is on the money, The reason to use plate and not build a tubular merger is cost. And either way a tubular merger would push the turbo out at least another 80mm.......into the strut.

I have thought about scalloping the tower to allow more room but I'm not that keen on that idea at the moment.

Picture of the underside, curved pan and some very small pieces of flat steel to lead to flange.

its more work but moving the flange spot forward you can fit what ever turbo you want.

Hey oda, not sure what you mean?

Okay you mean get forward away from the tower? I'd be inclined to tilt the flange upward.

This one was made to suit factory inlet manifold, the previous high mount manifold will work with bigger turbos..

don,t forget the turbo flange your using only fits certain size turbos not any turbo to what people are saying

Manifold finished and fitted with fine thread bolts.

What size turbo are these to fit? T25 i am guessing?, actually what would be a good size turbo on a a12, with stock cam etc, just one that would boost to about 15 psi on the 1200?.
