Default 1999 OBS, minor mods

Hi there, I have a 1999 OBS. So far I have change the air filter and intake, headers, no cat and free flow exhaust. What numbers should I expect in a 0-60 run, or are there only minor changes? what else can I do? thanx

cams and ECU work.

You should have decent gains from that setup. How does it feel to you?

I feels a lot better. Easier to accelerate and better on gas. Now, I live in central america, so the ecu option is out of the question, unless, you direct me to a web page where they sell power chips or such. I was thinking on going with the lightweight pulley and magnecore wires. are they worth the try? thanx

I'd settle for putting an EJ25 block under those heads adding Delta cams and calling it a day. You can expect a 0-60 time in the mid to upper 6 sec range.

Like I told you before, I live in central america. That means, no swap!! Do you think the pulleys will help me? how about the wires?

alejo... niec. pulley will help enough to where it is worth it to get one. it reduces rotating mass and helps the car rev faster.
