ok well I've got magnecore wires and denso plugs, and I know those can add a few HP...but what about a MSD coil and ignition? Can that add an HP? What would be the advantage of having these and how much would it cost?

Thanks,
Chance

Also how much HP would an ECU add, and what are the disadvantages of having a Jim wolf ECU?  Better gas milage? Worse? The same?  Can it lessen engine life?

Thanks,
Chance

You're not a dork. Good plugs and wires will make an unnoticable difference. A good ignition system will give you MUCH better spark and your engine will run REALLY smooth. You'll notice a difference in idle right away. JWT ECU gives a few horses by remapping the air/fuel ratio and other stuff. It should give you worse gas mileage, if I'm correct. You can get an MSD ignitions for $319.95 (2 coil packs) or Jacob's Ice Pack for $324.95. The spark output is like a 15% increase.

Enuff info?

I'm not sure about the gas mileage thing on the JWT computer.....when I switched ecu's, I didn't notice any difference. &nbsp;maybe I'm an exception...anyone else have the JWT ecu?

As for the wires and plugs, I found my Nology Hotwires did make a noticable difference above 5K RPM's (without platinium plugs).

From what I have heard about the performance difference of ecu's, for the money you should invest in more REAL sources of power, like a set of cams. IMO

It depends when you get the ECU. After you make a lot of changes, an ECU will give you a lot more.

That's very true. &nbsp;I was refering, and I should have said this, to people starting off with upgrades. &nbsp;For the price of an ecu you could gain more power for less money with other mods, &nbsp;CAI is another good one.

if you guys are running those turbo sil engines then you should really look into upgrade the ingnition system. dont want to lose power cuz of bad or weak spark.. i used plat +4 on my SC corolla .. i dont know what im running right now im my 240sx..

does it need plat? or copper?

I've always heard that, with the exception of running the right plugs with the proper gap, wires and an aftermarket ignition would only start to help you when you were adding significantly more fuel and air. &nbsp;I've never seen a dyno plot that showed an hp increase from this mod on a basic-bolt-ons car. &nbsp;It's always someone's ass dyno that claims good results.

An ECU, on the other hand, is probably the best mod for the money. &nbsp;The factory tunes cars to run safe and efficient. &nbsp;An aftermarket ECU can be tuned to run at performance levels, rather than economy levels. &nbsp;Plus, you can have it mapped to maximize for the mods you have. &nbsp;That said, I would hold off on an ECU until I had the bolt-ons that I wanted so I could get them to tune it to provide me w/ maximum gains.
