the basic concept of the stroker kit is to lengthen the stroke of the piston causing more area inside the cylinder for the molecules of air and fuel to mix in return a bigger explosion in the combustion chamber that forces more power onto the piston making it move faster! i have heard from a lot of people that have put a stroker kit on there car whether it was turboed or not that the inprovement was so nice that they would never go back! it revs faster yet not as high, and for a turbo car there is basically no lag, if barely any at all! i was planning on doing the kit for my car over the winter but i got the GST and things just didnt workout for the whole stroker plan, oh well! just make sure you get lowered compression pistons like 8.5:1-9:1 if you are goin to run turbo... as for fuel and timing get a datalogger and AFC and that will help you out a lot! they have yet to come out with a DSMlink for the n/t motors and i doubt they will for awhile if they ever do... so go with pocketlogger or another source of datalogging cause you will need it! good luck man, take some pics and let us know how it turns out!
