ok here goes ... i am building a sy ty engine for my 86s10 blazer... now i have a block vortec heads upper and lower intake fuel rail manifolds and crossover.... now i still need to rebuild the block to what ever specs i want .. should i find a stock wiring harness and ecu and start from there and then tune using that ... i dont really know my options i mean i knwo of FAST and going that way but does anyone have any sugestions like should i go stock ecu and go with a chip ... i mean i havent decided cam turbo size pistons injectors anything yet so i dont knwo if i should see what chips are for what mods and then build around the chip or what any help would be awsome i want to get going on this but i am at a hold up doing all the research i figure i better do it before i start spending more money....
With the amount of money you'll likely spend to get this finished, I'd recommend an Aftermarket ECU.
A pull-out SyTy harness will likely have some problems. Heck, they have problems when they're in the truck.
Your injectors/cam/turbo should be a function of your goals for the motor. Expect to spend a *lot* of time tuning once you get it done. Most importantly, *know* what you want before you start, and stick to it. If you keep changing your mind, the project will turn into a nightmare.
Don't get sucked into the "I'll start small, and grow into a 10-second build" myth. You'll spend faaaar more money that way than if you just built what you wanted in the first place.
You will need 1 of two things:
1) A lot of money
2) A lot of time/fabrication skills
If you have neither, I'd really suggest another project. Not trying to rain on your parade, but there have been literally *dozens* of people who tried/wanted to try what you're doing, and I can count the ones who finished on my fingers. Food for thought.
