Anyone seen my marbles?
 

Lost my marbles, I'm thinking of stroking out the ZJ to a
4.7 with the Hesco kit $2,270 and using a local shop in
Norman Oklahoma (Kennard Automotive). They have done other
work and have a highly recommended engine mechanic.
And yes, I'll be keeping the supercharger too. :D
Gonna definitly need larger injectors but might need new
ones anyway.

At any rate I'm going to have them do a leak and
compression check on the engine. I think I might have
toasted an exhaust valve and that's the reason the engine
is running rough. Probably a cascade from a bad injector.
(All stuff I can't check myself) :(

...the hose on my compression checker cracked..

Anyhoo, it's a far sight cheaper to go this way then to
pony up the bucks for a new Jeep and then fork over mucho
higher insurance and tag. Actually the whole exercise will
pay itself back in about two years.

As a plus, with increased power I can step up in tire size
and start converting the mostly street ZJ into something
that can provide more fun factor on future off-road trips.

(or put some phat spinner rimz on it and hang with da homies)

That's a scary thought, too lean and you'll melt a piston in
seconds of the first full throttle. I'd surely find the injectors first.
Check with your pump manufacture. Or maybe really go fast with a Holley,
were you know fuel mixture remains the same, within six percent.
I do like your spinners, though:

Dangit Bill, now I have to wipe coffee off the monitor. :D

Know what you mean about going too lean with that type of
setup. With larger injectors that should be ok and I may
have to build a safety system. Tap the O2 sensor for an
internal gauge and add a knock sensor along with a electronic
sending fuel pressure gauge. I'll just sister it with the
vac/boost gauge and mount the knock sensor light in the base.

Last time I was out at a car show (just attending) there
were a whole lot of folks asking where I got that. :)
My answer is simple... ACE Hardware.

I've read on using the stock O2 sensor and an O-Scope to see
what's going on. Problem is getting it to synch up and the fact
it gets HOT under there. Figure the shop has an engine analyzer
that can do what I'm trying to do without burning myself (again).

Re: Anyone seen my marbles?
 

not sure how you control your current injectors but a cheap option thats as
close to a standalone as you can get is the megasquirt unit.

it can be made to handle extra injectors (onset at boost) or larger ones, or
secondaries, in conjunction with oem's, etc... and can also be modded to
control spark timing

handles most of the functions of LINK-II or other 1000.00 standalones, for
about 200 plus a handful of cheap GM sensors.

its very homegrown and DIY, so it should suit a jeep perfectly ;)
