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)

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.

time I was out at a car show (just attending) therewere 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).

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 ;)

:) Sounds like fun. I'll stick with trying to diagnose the problem with a stock computer, but that would be handy for someone working on upgrading an older motor.
