help with borg warner turbos
going to order a new borg turbo, just a little confused about the designations on FI's site. i see alot of references to "s476r" whats the r stand for? on FI's site there are also turbos with "etr-ho" after them, not sure what that stands for. also hear people refering to the "gangsta" s476, whats the difference? im leaning towards an s476 with the 83mm turbing in a 1.25 t4 housing. debating getting the race cover. it will be going on a stock 5.3 with a lil jon specd cam, stock heads, proflo intake, th400 with a brake, probably 3.49 gears, truck will weigh about 3000 lbs. hoping to make 7-850hp at the wheels. the 83 turbine was recommended to me because i want fast spool for the street, do you guys think its going to choke on my motor? leaning torwads this turbo after seeing how well stock48's nova ran with it. i would be perfectly happy with 8's at 150 plus. thanks for any info guys!
