well had a result today i turned the original manifold upside down and bolted it back on and it leaves the downpipe flange up front and facing up
so ive cut the flange of the downpipe and started making a swanneck type joint like the cossies have. ive got the turbo and an rs turbo wastegate housing and downpipe set in place where i want it right up front behind the headlights. so ive read with some more fuel and 7 psi should be somewhere between 220 and 250 hp
it wont win any concourse awards thats for sure

but with a welded diff and possibly 250 hp will be a decent winter blast.
