for injectors....depends on how much hp you wanna make in the end....right now im using 450cc dsm injectors but they max out at around 300hp.....so im upgrading to 750cc which are good up to 450whp or so.....but i plan to max the engine out on pump gas....so it will only be around 350-400hp....so if you plan to make more than 300 then go with atleast 750cc injectors....but if you plan to make less than 300hp and stay there then go ahead and find a set of blue top dsm 450cc injectors....
for the turbo....look into Holset turbos.....go to ebay and search "Holset HX35" the hx35 has FAST spool (can get full boost, 30+psi by 4K ) and makes AWESOME power (maxes at around 550hp) .....and there cheap to ....should be some for around 300 bucks on ebay.....and there just as good as the $1000 ball bearing garrett turbos....
for the wastegate....go with Tial....ive heard awesome things about Tial products....
for the blow off valve (dump valve) ....search Greddy Type S .....HKS SSQV.....and XS RFL .....those are the best sounding bovs .....
just get a chipable ecu....that way you can take it to a dyno to get it tuned....
