alright so i have a d16z6 with about 150k on it, runs nice no knocks anything like that, but just to be safe i was going to do vitara piston and eagle rods, now i believe the normal bore is 75mm if im correct, so i was wondering if it would be reccomended to punch it out to 75.5mm or if i should keep at at stock bore, if the 75.5mm is reccomended how much could i expect for machining? and i have in mind a t25 to try and reach my goal of 225-250 WHP, is this the correct turbo for me? i have heard some good and bad on this turbo, some people say it spools fast and holds strong up top, other have said the opposite, any opinions on this? it will be a DD so i dont want too much force on the motor, now about the tune, i have been looking into wicked inovvations to send it to them to get my OBD1 p28 ecu chipped, now.. depending on what program my tuner wants to use, do i just send it in and get it chipped for that program, will i need anything else after that for tuning if i plan on having a professional dyno tune it? sorry im very confused on tuning mainly, any info will be appreciated. thanks ask questions if needed.
