TPI From LB9 on a L03
I know a TPI off of a 305 LB9 will fit on a 305 LO3. What I need to know is how it will profrom? The LO3 with the TBI has 170hp. And the LB9 305tpi in my 89 iroc-z is 195hp. The C.R. on both are 9.3:1 Would the HP be 195 are closer to 170? If you know anyone that has done this or if you have any info please help. Thanks

I installed the TPI intake and computer on my 92 RS 5-speed, with no other changes. It made 17 HP and 70 TQ more at the wheels. It went from 158 HP to 175 HP, and 220 TQ to 290 TQ. I later installed a TPI cam and it went up to 187 HP at the same 290 TQ.
Remember you have to change the computer and wiring harness, too.
