Seems high in price. The TBI kit is only about 350CFM. That is small. I have a similar setup with the Holley 670CFM throttle body. You need at least that much CFM.
I love FI. If I had it to do over again I would build my own TPI system from a donor car. Can be done fairly inexpensively.

Holy C*** those are expensive. I bought a complete speed density TPI setup (wiring harness, computers [ECU & one for the trans], all hard parts and sensors, dist, etc.) from a 92 firebird formula, on craigslist for $450. Theyre worth it, at half the price listed on that link. my 2 cents.

Yeah but that's usually used oily parts off a used engine with a used harness and ecm that is specifically designed for the car it came out of....including VATS

There is nothing wrong with buying a complete used intake system, I guess it depends on how much you want to put into a system like this to get it up to par as the new stuff or if you just want a driver to beat around town in.

I pieced mine together using new stuff (except the actual TPI intake) and I had well over $2000 in mine when done.....so the first link is about right.
