Hello all, Realize this is my first post and don't want to come off like a "dreamer" as this question could easily be mistaken for. I'm trying to gather info to decide a route I will take in the near future. I'm a hobbiest fabricator and have boosted quite a few vehicles over the years and own alot of my own equipment.
I'm not after big power like most that i've read on here but more after efficency. I've always wanted to do a smaller turbo engine in a larger vehicle strictly for fuel economy and after driving my fathers ecoboost f150 sealed the deal for me. vehicle is a 1/2 ton 98 suburban 4x4 with a tired 5.7. debating between the 3800 and 4.3 vortec. vehicle's use is more along the lines of minivan status with the occasional hunting/camping trips. won't be towing a toy hauler or anything like that. (drive it 800-1,000 miles a month)
Here's what i've gathered the series II L36 and L67 is a good platform. L67 having stronger internals but needing the L36 top end swap or gut the blower with endplate for a turbo setup. the 3800's will need a 60' V6 trans or at least bell housing, convertor, flex plate, starter, front pump and input shaft. ecu/harness needs to be 97-98 for programability/ not fly by wire.
300whp/350wtq would be more than adequate which is why i'm leaning towards the L36 for simplicity/cost factors. the 4.3 vortec would require a new intake setup but would also be bolt and go for the trans/engine mounting portion. not to mention i've found little info on boosted 4.3's.
sorry for the lengthy first post. hope some of you guys can shed some light and give input. also is there a dyno thread anywhere so I could get an idea of some setups
Thanks, George
