My completed TBI mod'ing expirience fananza!

So I tore into my TB yesterday and today (leaked a nice amount of gas in the drive way because the guide says nothing about the TB removal :-X ) but I got it off and took a look at the setup. I absolutly love the thing, its like a move uptodate carb. I did the ultimate TBI mods, added injector pod spacer and TB spacer. It was a great sucess despight my dad looking over my shoulder saying "Your a moron your doing machine work with a dremel...your gonna have to pay the mechanic $400 for a new TB and I'm not helping you with the cost". Got everything back on my engine with my dad standing next to me and it started the first time That felt good to be right for once. Took him for a ride and all he says is "Wow this feels nice the auto is even shifting better". So all and all a good experience Ultimate TBI mods + spacers = way worth it!

next time you go to disconnect your fuel lines, take off your gas cap and relieve the pressure in your system, then you will have verry little gas dripping out good things bro, any questions feel free to PM me and ask on here or NJFBOA

in my experience that doesnt work. the better way is to start the car than go under the rear and find the 3 prong connector just over the rear axel and in front of the gfas tank, and unplug that whill the engine is running. after the engine dies the system is depressurized and virtually no fuel will leak out.

i always just pull the fp fuse, crank the engine a few times, and viola no fuel leak. then again even w/o doing this, ive nvr had a lot of fuel leak out.

anyway good job on ur work... my dad said the same thing when i was "carving into " my tb.
