Tbi swap build thread

Before I did my conversion I put together a spreadsheet with prices for each component. Spreadsheet is all inclusive - as I've captured used and new parts prices. IMHO $400 for a complete TBI setup including aluminum intake is a nice & convenient package, although the same can be done for little bit less provided that you are willing to search JY's. If this is not the case the following questions must be asked before committing to buy:

1) Intake manifold - What is make and model number of this aluminum intake.

2) ECM 1227747 is listed - what the BCC code.

3) Injector part numbers or color codes (did it come of 305 or 350 CID engine)

4) ESC part number.

5) Dizzy - small hat dizzy - confirm.

6) Also confirm that burban tank can fit in your blazer!! I use rockauto.com search engine that has where used feature - very handy when doing swaps.

You can get BOSCH style relay and socket from any worth while auto parts store. Alternatively, look for 80-90 GM cars at you local JY. MY favorite target (very common in So-Cal) are 4.1-4.5-4.9L front wheel drive caddies as they have a bracket with three relays mounted in a row on a driver side strut tower. When poaching harness make sure to get at least 18 to 24" of wire at the socket. These are 30AMP rated relays, just make sure that wires size is about 10-12AWG. You can wire your winch (provided that it does not exceed 30 AMP current limit)
