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

its not exactly a nissan so didnt think it was appropriate
 , although it is a nissan and engine and box.tyres are Kumho Ecsta V70A in soft compound. They are currently the softest road legal (List 1B) tyres on the market, so make them ideal for the sprints and hillclimb events i use the car for. Ive used Yoko 32Rs and Avon ACB10s but none are as soft and sticky as these, in fact 3 laps of castel combe and they are overheated  . They are actually their Formula 3 'wet' compound rubber but on a (ultra stiff) road carcass. Although i havent used them, the medum compound are supposed to be an awesome trackday/race tyre, in fact they are used as the control tyres in TVR, Porsche 924 and BMW circuit championships too. my car runs 7" fronts with 205/50-15 and 9" rears with 225/50-15.

ok manifold is 90% finished now, have just cleaned up ports with die grinder and tungsten carbide burrs (crap photo
 ) just needs the flanges surface grinding flat as they have warped during welding even though it was bolted to an old head. Was expecting it tho, thats why the flanges were cut 15mm thick to allow for skimming.
