turbo tbi question

flyinhillbilly · 01-07-2007, 08:58 PM

hi everyone, i'm a newbie here, i was referred by a turbomustangs.com member that told me if anyone would know these things you guys would.

the question is i have a 94 k2500/5.7/4l60/14 bolt 6 lug. i'm wanting to turbo it, i have done turbo projects in the past and am familiar with megasquirt. i want to keep the stock ecm controlling things,will the stock ecm recognize boost if i install a 2 bar map? if not is there one that will that is compatable? i have contacted one person who says they can burn a chip that will be fine to 7psi, does that sound right? i figure i'll seal the throttle body and drill a hole in the side of the regulator spring can thereby boost referencing it, and install a walbro 255 in tank pump, and use the carb hat off of my turbo'd 75 farm truck. i don't want to run over 7psi, i just need more towing power for dragging my race car up these arkansas mountians, does all this sound reasonable? thanks in advance for any help suggestions

ok, i appreciate it anyway. i've been reading around on here and you all seem like pretty good people to me, i'm a mechanic, and make my living working on chevy trucks because there's so many around here. i may try that chip and a tubo, it would be cool to kind of pioneer something for once.

i've got the turbo part of it nailed, i'm more needing help with the tune on the ecm.

you might take it to a speed shop and have the tune the ecm.

As far as the stock ECM goes, I don't think you can use it with the boost. You'll need a tweak up one to accomadate for more air and fuel when the system calls for it. As for the rest of the stuffs, I can't help you there.....sorry. But when you get this figured out keep us posted on your project. Would like to know how its turning out.
