    1989 S10 Short Bed 3 step project

    Hello everyone. Complying with 1st post requirement.

    Starting 1988 S10 2wd shortbed project, 4.3 V6 and auto trans original.

    Step 1 - Install donor 1988 305 / 700R4 from wife's t-boned truck, 140,000 miles and keep TBI by changing ECM from donor (1227747). Exhaust to sky for now. Get running smooth.

    Step 2 - Obtain (10/10/20) 1991 Formula 305 TPI and install on 305. Use 1227730 ECM and EPROM, re-pin harness and and get running again smooth.

    Step 3 - Obtain (2) ebay turbos, fit to engine and TBI, order and install Dynamic efi EBL P4 Flash, tune and drive.

    Not too much to do, right.

    Will update as progress made.

    Well you had a nice, mild engine swap going 'til the turbos got mixed up in this. Are you planning to run intercooled as well? Or are you challenging the limits by skipping the cooling?

    BTW, welcome to the forum.
