BTR stage 4 turbo cam help Hello guys,
I need your opinion and tech advise.
Im building my first turbo car, I've decided to go single turbo. car is not my daily, but i enjoy driving usually on weekend and for spirited driving/track/car shows.
(Cam and stall have not been installed yet)
Cam specs are 234/239 .612"/.610" 115+5 (BTR turbo stage 4)
Stall 3400-3600 circle D
stock gears 2.92
stock bottom end
motor 6.0 L76 / Ls2
i would like to stay around 8-10PSI
my question is how will this Cam behave with a medium size turbo 77-85mm? fast spool? should i change cam or what type of turbo?
i've seen other threads with same cam but people have big turbos and they don't start making boost untill 4K-5K rpm. i would like to make boost a bit earlier. should i rethink my cam or send it?

Had a stage 2 LJMS cam in my 6.0 with twin 66's. Ran great and even had a nice mild lope at idle that I didn't expect. Boost came in strong around 3500 rpm and pulled easily to 7k. Originally had a Yank PY3400 with 3.50 gears and a 31" tire with a glide in a 3400 pound car. I would definitely say go with a smaller cam with that combo.
