Ideas And Comments Needed
I have a '89 Blazer S-10 4x4 with a 4.3 TBI. I want to make more power for use both on and off the road. And I was just wondering if anybody had some ideas.
What I was thinking of doing is starting with intake/exhaust. I was thinking of making a ram air intake, or using a cowl hood with an open air cleaner, and flowmaster or magnaflow cat-back system, probably with headers.
Then move onto the intake manifold. I was wondering if I could convert the older TBI system/intake manifold to multi-port injection. I figure if I could, then I would have to get the computer tuned, so I would do that next.
Come to think of it, I should probably do internals before the intake manifold/throttle body, I'm thinking stock compression forged pistons, (not sure what the stock compression ratio is on this truck) and a high-lift cam?
Anyway, anybody have any ideas, or comments on my ideas? I'd love to hear them all.

RE: Ideas And Comments Needed
sounds good. the 4.3 motors are pretty durable motors so you might be able to get away with the stock internals for now and do a mildly tuned cam. i dunno if the have a multiport injector kit for that year 4.3. i know with the 5.7 they have a complete kit for that application. in addition to doing the intake and exhaust you could do an underdrive pulley kit and a high flow thermostat. possibly instead of doing multiport injection you could do bigger injectors and chipping out your ecu?
