Sounds and looks pretty good to me. You need one adz. lol and an external wastegate

ok bit more progress......
ive finished the majority of the welding and fabrication now, just needs all internal welds tidying up with die grinder but my compressor is crap so gonna have to borrow another to finish the job. Once thats done, i will set about making a 'cradle' brace from the rocker cover and spare head casting bolt holes to suspend the assembly with a couple of rosejoints. Its essentially to allow movement with the heat expansion, but help to stop it cracking. Google for Bailey cosworth turbo mount and it'll make more sense. Should stop the stainless cracking as easily. I intend to wrap the manifold in exh wrap, from the manifold to the tailpipe pretty well. i know many people arent fans of the stuff, but i like it and it keeps the heat energy in the manifold and outta the engine bay (and cockpit as exhaust runs inside the car with false floor and out the passenger door!) which on a little fibreglass car isnt funny  heres some more pics

You may get problems in welds cracking if you didnt use stainless steel migwire as the two different materials could expand at different rates when hot. (I speak from experience on mine) I did a rush job welding up a split on my stianless top mount manifold with normal migwire and its split again
 . I will be stainless tig welding beofre i fit the t34. But your welds look pretty heavy duty so fingers crossed. The rose joint idea sounds good, Maybe i will try that myself as we have a lot of them lying around at my work. the fannymolds coming along well, has the external wastegate flange arrived yet? What Turbo are you going to be using?

it is stainless MIG wire, but to be honest i do expect it to crack eventually, its par for the course as they say. Luckily the car is only used on track so doesnt do high mileage.
Heavy duty welds? more like amatuer LOL. Im not an expert, but hopefully will be ok. Im gonna use my current turbo which is a T28 hybrid (cut back and 360deg etc) that Turbo Technics built for me 2 years ago. Low lag spec and with a T25 exh bolt pattern. running 16psi at 250brake at the mo, itll be intersting to see if the manifold gives any more power or torque (like the CA20 inlet manifold did). Flange hasnt arrived yet, did you send it to my work? if so we arent officially back yet, so postie doesnt deliver. Not sure if im gonna use it yet, may run it with std actuator first, then change to an external wastegate later, so i can actually see what differnce it makes.

Yes it was the address that was given with paypal, (work addy)
You will be alright then,i couldnt be bothered to change the real in the welder and just wanted to get my car home. . Also the gauge of the tube on my manifold is really thin and weakened either side of the welds. At least you stand half a chance of yours not cracking, Hopefully i can make mine stronger when i take it off next. Look forward to seeing a few pics of your engine bay
