Holley TBI injection to TPI
Currently I have the Holley commander 950 TBI injection system. I want to go MPFI and I've been going back and forth between a single plane MPFI and TPI. I like the look of TPI and I'm worried about the hood clearance with a single plane intake. I'm close to the max duty cycle of the TBI injectors (~500hp), so now seems like a good time for a change.
I want to get a used TPI intake, runners, plenum, and fuel rails since they seem to be found fairly cheap. I'm not sure whether to go with the stock TB or if I'll need a higher flowing one? Then, I'll need new injectors and 48-50lb ones should be good, but I'm having trouble finding where to buy them.
I'll still run everything with the commander 950, but I'll need to change over the TPS and IAC sensors. MAP, O2, wiring harness, and fuel pump will stay the same. I'm looking at a holley afpr.
Let me know what you guys think about going TPI and also what throttle body and where to find high flowing injectors. Thanks
