Re: Convert my TBI to TPI
You could also think about switching things up a bit and doing some mods to the TBI system to make more power. I'm working on a 91 Chevy truck and my current plan is to go with a 4bbl intake with EGR port, along with a TBI to 4bbl adaptor and a new TBI unit from Xtreme EFI. According to the ad it flows enough cfm to feed around 340 hp. Also might want to add a better fuel pump and an adjustable fuel reg to help increase line pressure and have a chip burned to make it all work together. TPI's look sweet, no doubt about it, but if you're on a budget or like to keep things simple, might want to look at souping up the TBI. The TBI's are simple and I've never had an issue with mine. But again, like Kevin91Z said...do your research...theres tons of info about this swap out there. But if you just want to make a little more power and don't care about looks, the TBI can be made to work for you. Good luck.
