How it will sort of look when done.

If it doesn't work Out I will just get a new turbine housing and then mount the waste gate on the manifold like normal. People do

Mounting the wastage on the turbine housing is the most efficient place to mount it from the information I have found.
OEM manufacturers do it on their turbos, most likely due to packaging constraints but also for efficiency as you can run a smaller WG

The Borgwarner EFR turbos have internal WG too and work well on rotaries I think.

I could have maybe used the smaller 48 WG but iv had this 60mm Tial for years, and bigger is better right

Having the WG on the turbo makes it more serviceable too instead of hidden down low

Hopefully not.

Need to do some searching, see what kind of boost a stock block C as n take... Hopefully 20-25psi at least

Very trick, I will be interested to see how this works, hopefully it wont cause any issues.

100% Not a criticism just an observation, flow wise if this causes issues, if it were me, I would have put it as close to under the flange as possible.
You probably know this but if you have a problem you can have the piece welded back in by using cast iron ark welding rods, so you wont junk the housing that way.

Like I said  hopefully it wont cause any issues and its really great to see you getting on with the car :great:
All the best Clive

I would just buy a new housing rather than welding it.

Possiblity that the rear housing is too small BUT as the engine isn't fully balanced clearence etc then I don't want to be revving it really high so spool up the turbo sooner

And.... I will be getting a bigger turbo simply because a bigger turbo shifts more air for the same psi so more hp for the same amount of boost in theory. Looking at s480 for the future but no point paying for a turbo when I have a turbo sat here ready

Any chance you could take a photo of the mx5 undershields please.
My dad put this car back together and I have massive gaps either side of the radiator, I'm certain he put the undershields on wrong
EDIT no wonder they don't fit. The one fitted to the car is a mx5 nb/na

Managed to get AGTHAB into my garage, push it to the bottom of the drive and then used my dad's car to push it up the drive into the garage.

Waiting on a flange coming from the states which is stuck at the post office waiting for me to pay customs charges but I haven't recieved a charge in the post for me to pay it literally been sat at the post office since the 10th but iv had no customs charge letter

Interesting view of inside the turbine housing to see how the gases flow onto the turbine wheelhttp://cloud.tapatalk.com/s/5eedf248b73d2/VID_20200620_113628.mp4

I know that feeling
Mine bits are stuck in Coventry and I’m waiting for payment details

It's really frustrating because I can't do anything to get it and if they send it back it will go back to America

On the plus side iv just ordered some stainless bends and a straight 3 inch piece for the exhaust, so I can do that once iv got this flange too.

Intake and exhaust will be completed then time to move onto radiator, oil cooler and fuel cell mounting

Currently sat in my car waiting for the turbo manifold flange to turn up as I managed to locate and pay for the import duty
