This may be a stupid question, but I need some advice. In reading an old issue of Mustang Monthly (the one with "building your own Elenor" on the cover) they had an article on upgrading your stock ignition. In the article, they upgraded the ignition on a fox using MSD parts... a 6AL ignition, new coil, wire harness and wires....

Now, to the point. I am thinking about doing this but a buddy of mine asked me why. Now I'm asking myself, what would be the benefits of doing this... and I am not sure why. The article doesnt really go into much detail as to why... Can anyone help?

I want more info before I jump into this process... its relatively easy to perform, that's not what I'm worried about... It's the cost of the parts.

thanks,

It's true, your '90 already has a pretty decent setup. Unless you really need it, {higher rpms, bigger injectors, etc...} you'll be spending money for not much payback.

Steve is absolutely correct. Unless you're in a high-horsepower situation already or are planning to do something major in the near future, spending all that money isn't really necessary. Your stock ignition is more than adequate if its in good condition even with moderate mods.

Thanks for the advice, I think I'll stay with the stock ignition... Here's another question... what would be the maximum HP that one could or rather should go to before upgrading the ignition... just curious.

You're good to 400-450hp, at least.

I agree that the stock ignition system is pretty good for most street applications.If you are planning to run a supercharger or a big shot of nitrous,maybe it's time for an upgrade ,but for naturally aspirated cars it will work just fine.The only thing I have changed in my ignition system is the coil,the stock one was weak ,so I put in a crane coil to replace it.

OEM ignition is great, the only reason I can see to upgrade would be for features like stutterbox and rev limiter (and the rev limiter is definitely a good thing in a stickshift car).
