I agree, I'd buy chris's manifold, su's don't cost to much I bought mine new old stock $75 plus post, t25 of a rb26dett is a good size and you can find some with carbon seals fitted standed or get one rebuilt with steel wheels which means u can run more boost, water/meth is also a good cooling agent if you look at cooling mist's web site they have many available, there are a few other things like oil/water lines, throttle cable pending on how u mount carbi and where, the small things add up, mine cost around $1500~1700 to get all the bits and get it going but still needed a tune but parts are easy to get for su's there's heaps of info if you google draw through setup's and learn along the way
