My original idea was to put headers on it but TTI's and full exhaust run close to 2k in Canada so I'm hoping for a better option.
Opinions?


Based on your opening question and some of your responses I think we need to know your budget, and your expectation. Certainly you can put headers on the car for far less than $2000. I also think that that a different cam will put more power in it too.

Your car/motor seems to run about right for what it is, and making any one change will not likely yield a huge gain.

Are you running your current combo on pump gas? If so, this surprises me. What is you cranking cylinder pressure?

If you go to a cam swap, I would go with a small solid


Currently yes I only use pump gas but it tends to knock on 91 octane so I pretty much only run it on 94 which I have easy access to.
If I go the headers route I will also swap the cam since I think it makes sense to maximize the benefits of it.
It's not so much a budget issue as much as cost per benefit, 2k just seems like a lot for an exhaust swap. The exhaust I have now is all original so I kind of like it as is. My hope was to gain 30hp without switching out my current exhaust but that may be unrealistic.


102 is a Nice MPH. My opinion? A good set of DA shocks will be a better ROI than the same amount on chasing the HP left on the table.
