I know this is primitive TBI, but I really want to install generic GM TBI unit in my 3.5 liter TR8 with 600 cfm Holley, Edelbrock performer manifold, mildly uprated cam and headers. I have researched this and feel comfortable with all aspects except:
1. Controlling vacuum advance. I have a Mallory Hall effect distributor and have read that some installs maintain old advance mechanism. ( I still have the OE dist) Computer controlled advance seems to be necessary..... What are my options?
2. What kind of vss do I install on the stock 5 spd tranny?
3. Maintaining AC is important. I think the ECM needs to only know when I turn it on(?)
4. Which parts should I get from the bone yard? I think I know which throttle body, fuel pump, ecu, o2 sensor to get. Would a wide band o2 sensor be a good addition?
5. Some sites say ECM reprogramming is not necessary. Since I am not using EGR or concerned about emissions in any way, I want to maximize reliability yet get performance, I think a concientious reprogrammer is a good idea but I've read that some vendors really do very little to maximize operation.
6. Am I nuts?????
THIS SEEMS LIKE A GREAT PROJECT.
what do you hope to get out of it?
