Interesting OLD thread.
Where are they now?
Parted put. Sold the engine without the supercharger. Where is that SC now?
I doubt they even got the throttle cable hooked up. Lots of tubing, lose the A/C, hood won't close, questionable location for intercooler. Where is it now?
The way most all of the threads end. All talk and never do.
Sprintex system, 7th injector, Split Second FTC. Still running, over 35,000 miles since install. now up to 10 pounds of boost, big valve, ported head and 265+rwhp. Inspired M62 supercharger kit.
Where are they now?

I should be the first to say after spending about a week and a half more into this I did find the error of my ways and find that there is simply no way to cheaply do this, For an OBDII anyway. Electrically tuning wise, parts wise it would've cost me minus the stand alone and the wide band....$600. Had this figured out but did not have the money to reflash my computer or get the standalone to make it manage my fuel so I didnt burn a hole in my pistons from running to lean. Shortly after ordering a few things and getting them on the jeep I planned on keeping was either going to be taken from me and crushed or taken off the road so I had no choice but to sell it. It has been replaced with two since then. I put my money more towards something that was IMO now more worth my time. So to end my rant, its not coming. Threads dead until I can find a standalone for cheap.
On my 2nd gen I replaced the whole fuel pump assembly with Bosch replacement, replace the plugs cap rotor and coil (supposedly a "hotter" coil), upgraded to one temperature range "colder" spark plugs and gapped them to 35 thousandths, and 703 injectors. I have a 70mm billet throttle body, but a bored 62mm would work fine.
