jaytoland80 Posted January 26, 2010 Posted January 26, 2010 I currently have a 2.2 subi non turbo, I do have a turbo for it but do not really want to put the money into the computer and so on. So I am thinking of running a 4.3 throttle body. What would be the pro's and con's of it? If I were to run a vortec efi how hard would it be to hack up the stock wiring harness. I hacked up the stock subi wiring harness for stock computer. Quote
ltr450rider Posted January 26, 2010 Posted January 26, 2010 4.3 TBI basically means, expensive carberator. Go EFI, much easier to tune and been around the longest. I dont know about hacking the harness though. I've heard some tuners can get 250hp out of EFI with the right programming. Quote
Don29palms Posted January 26, 2010 Posted January 26, 2010 Throttle Body Injection is Electronic Fuel Injection. Quote
barefoot bob Posted January 26, 2010 Posted January 26, 2010 4.3s are sleds, go honda, cheaper and way better upgrades Quote
dunefreak Posted January 26, 2010 Posted January 26, 2010 ^ yep, what he said. 4.3L's are pretty heavy and underpowered, especially a TBI motor. I would also lean towards a Honda. Quote
ltr450rider Posted January 27, 2010 Posted January 27, 2010 Throttle Body Injection is Electronic Fuel Injection. Yes Don, TBI is controlled electronically. Thanks for pointing that out. Quote

I believe you were thinkimg about tuned port injection versus throttle body. I would stay away from a heavy cast iron block motor anyway. If I had to choose between the 2.2 Subi or 4.3 Chevy I would keep the Subi. TURBO=MORE POWER! If you really want a V6 Honda is the way to go. Quote

I was trying to answer his question about the 4.3. Quote
jaytoland80 Posted January 29, 2010 Author Posted January 29, 2010 I have a Honda motor for sale. Well I have decided to go with the Honda 3.5 motor. I am up in Washington or Don I would probably hit you up. Does anyone know where to get the wiring diagrams for the Honda's? Its a 2002. Quote
