| well, first(and i dont know if you were thinking about it) but i would sway away from a single setup. its ended up costing a bunch more money than i ever intended. i also have some theory's (i'll elaborate below) as to why my setup might not be good. i would go with a proven setup. like the 2835's or td-06's(if going for big power) if going for anywhere inbetween, i say go td-05's, or 2835's. i think those will be your best bet. no, i havent ran the car at the track yet, other stuff has been getting in the way... i will be running it this spring, i have a dyno chart, but with my old turbo, it shows a TON of lag, and power that does not suit the lag well. it had t88-style lag and topped out at 546whp. i have now put on the SP74 and it spools quicker than the old turbo, and should make much more power. seat of the pants difference between the old turbo and this sp74 is pretty damn big, and i estimate i am getting 550-600whp @ 18 PSI. the restrictions now are the heads, but i dont know if i will mess too much with them besides just going cams, because my exhaust manifold will probably be the largest restriction of the system, so doing massive port/valve work would really not be worth the effort if the exhaust manifold is just going to restrict all the flow(this is just my theory). i think i am going to dyno in the spring to see if i can max out the stock head/cams, then put in some aftermarket cams and see what kind of gains i see. then after that i will decide if i am going to take the plunge and do some serious headwork. theres a dyno chart of the OLD turbo on my site. the old turbo is a swcheitzer turbo off of some caterpillar construction equipment. not suited well for my setup. new turbo = good. good luck with your choices. its tough, my first setup was t-28's, and that was a mistake. at least no one is putting them out on the market anymore for anyone else to make that mistake. you have a lot more choices and much better prices than what i chose from. -joel
