Not sure which project thread this belongs to but the 1.6 Mivec engine for my Lancer comes with quite nice extractors from factory. 4 into 2. I don't have the lower section, which must take it from 2 to 1. 

They don't look like press mends like the horrible Mazda one.

I have the MX5 B6 exhaust flange cut off (still with factory weld bead inside the ports), comparing this to the Mivec manifold the spacing is very close!

This is with the remains of the cut off mx5 tubes basically sitting inside mivec ports.

Could possibly cut off the mitsi flange and weld on the mazda one. Will offer it up to the engine bay when I get a chance. 

The design is MUCH better than the Mazda one, maybe it'll be worth modifying it to fit?

Really like this manifold research, are the bolt spacings similar at all?

If not I think I've seen people offering waterjet flanges for $50-$100 Could supply drawings of each and have a hybrid made up, best of both worlds, or continue boring out the mx5 one to fit.

How does the rest of the manifold fit in the engine bay, there is a lot of room there, but no risk of it hitting the frame rails there at all?

Cheers! The boring out of the flange isn't making it any bigger it is just removing the internal weld. The welds make it a smaller opening than the ports in the head.

The mitsi manifold spacing should work with the mx5 flange/port spacing. I haven't gone any further on this yet, other projects taking up any time I have.

I doubt the bolt holes will work but it's an interesting though, it might be possible to redrill it. But my plan has always been to cut of the Mitsi flange and weld on the Mazda one.

I am yet to confirm clearance, I think I will end up cutting the bottom section up to have it point more towards the rear of the car as it currently points straight down (which could still work but not ideal).

Wof'd again after almost exactly 2 years, had to put a set of new rotors on it. It was 3 degrees C and late but I wanted to drive it again :-D

Not totally done with the paint, probably going to have to redo the clear coat on the bonnet. Not sure what happened but it wasn't fully hardened so the 1500 wet sand put scratches in it. Very annoying but it looks good if you don't look too closely lol.

Drove it to work today and man it feels great, these are such fun cars to drive. Just makes you want to heel toe down shifts everywhere like an idiot.

Also feels really good with the upgraded sway bars I put on just before starting the 'just fix that dent'.

Smaller Momo steering wheel is much nicer than the stock one and a bit more leg room. A bit harder at slow speeds with the manual rack.

 

EDIT: typos.
