My 4BT does not have motor tags (so no clue about 105 or 120hp) but it does have tags on the Holset H1C the assembly number is 3525699 which after researching shows it has a 46cm intake and 16cm exhaust. I have a couple questions about upgrades if anyone has time to weigh in.
Goals: 150ish hp
I was reading the hy35 sticky and I saw where lots of folks upgrade to a 12cm exhaust housing for the H1C which seems viable
After talking to Gillett Diesel they instead recommended changing my INtake from 46 to a 50 or even 52cm and retaining the 16cm exhaust. Their point being that I could always upgrade exhaust side later. (all of these parts would bolt right up meaning staying at 2.5" piping and possibly making intercooling harder at a later date [which would use 3"])
I'm kind of overwhelmed with which direction to go.... I'm still considering a HY35 as well but know that I will have to change more plumbing if I go that route. As I stated I'm really only wanting to chase about 150 hp in a 5,000lb pickup truck (zf-5 transmission)
Can anyone who is much smarter than poor me weigh in with advice?
Sincerely,
Brandon
