Hello everybody,
It's time to put fuel injection on my Land Cruiser.
I've been a dedicated lurker on the list for a couple years now and I think I've
learned enough to slap a throttle body system on the cruiser, or at least make a
valient attempt at it. I'm in my sophmore year of Mechanical Engineering at Cal
Poly from which I've learned some useful things that will apply to this
project. I'm not babbling this info to try to qualify myself, but to shed some
light on my background so you might be able to answer some questions I have (if
you might be so kind :). The project is as follows:
1969 FJ40 Toyota Land Cruiser
Vehicle Weight: about 3800
lbw
Gearing: 4.11:1 diffs, 4 speed
manual trans, 35" tires
Motor: F engine: straight 6
metric clone of stovebolt six of Chevy fame, .030
overbore, .030 shaved block/head
around 3900 cc displacement, doesn't rev
over 4000 RPM
cast aluminum intake for 2bbl carb, steel tri-y header
My current short-term goal is to simply install a
throttle body/'747 system from a 4.3l GM truck or van. In the beginning I just
want it to work well enough to drive around daily. Question: Do you suppose
re-programming of the ecm will be neccesary? I assume the system would run
without any mods due to the similarities of the engine displacement, but I don't
have any idea of how well it might run.
My long term goal is to turbocharge the motor with
moderate boost (maybe up to 10 psi), fabricating an exhaust manifold using the
weld-el/sch40 method. I assume I will probably need to replace the MAP sensor
with a 2 bar unit, but I've not heard of anyone re-programming the '747 for
turbo use. Is this feasible for a non EE like myself (I have programmed in C and
other lanugages though and have a grasp of basic electrical concepts)? I would
rather not fabricate a new intake manifold for port injection, that's why I
picked the '747.
Please respond if you have any information you feel
might help in any way :) Thanx for your time and bandwidth everyone.
