I took it upon myself to make my own manifold from a cheap ebay job
(300 quid) and a flange. I didnt fancy paying a grand for one from the states, and waiting 3 months to get it.I started with this

welded on a flange
Another view of adapter plate on to suit my GT35, and smooth out the inside of the pipes leading up to the turbo
Next, I got myself this 60mm wastegate from GS Racing
(A few people I know have been using them for a while)
And needed to make it fit
- so I had to cut the old wastegate tubes off and weld in wider diameter piping and this is the result - not too bad if I do say so myself. Spent an age getting nice smooth lines inside the pipework. You can also see the spacer plate I had to have milled (Only bit I didnt do myself!)The red arrows in the diagram below show the bit I had to physically make in order to make the 60mm wastegate fit
- it was originally designed for a 40 something mm wastegate which I decided would be too small (You can see it the way it used to be in the pictures above). You would not believe how long it took to get the angles right on that damn thing. More than one time I was for throwing the lot in the skip and forgetting about it..
Now all I have to do is weld the wastegate flange on so it sits at this angle to clear the firewall, and I have me a top mount manifold!
Am going to be bracing it all up well so it hopefully lasts some time between cracking.
Finished it completely over the past few days:
Finally got round to welding up that last bit of manifold.
Took next week off work to hopefully finish the lot.few pictures of the finished article

some slight porting was required to match the gasket
