Fuel?

[chris97pittman]

Okay I know that usually everyone always says "Search". I think this question involves a new post because it's somewhat specific to mods you've got done to your car specifically. My question is if I've got this on my car:
Intake/Header/Exhaust/Highflo cat/55mm TB And I plan to get my intake manifold and head port matched, and get some streetable cams, do you think it's about time to start upgrading my fuel supply and/or ingition..I've got NGK plugs and MSD wires. Anything other than that though???

All those mods will make it easier for air to get pulled in and pushed out of the engine. You aren't really adding any extra air to the cylinders, therefore you shouldn't really need any extra fuel.

Although with extra lumpy bumpsticks, you may need fueling to help smooth out the idle a little bit, the ECU should be able to figure the rest out, for the most part.

If you are unsure, get a wideband. If you plan on turbo'ing in the future, go ahead and upgrade your fuel system.

As far as ignition goes, it seems as though the stock ignition system can handle about anything we throw at it.

N/A yes, but under higher boost, the ignition system won't hold up.

If you searched, then you would've read something about Mark's (bulletdsm) or Brian's (DR1665) setups. Both are all motor beasts that still run on the stock fuel systems. The only time adding fuel is necessary is when you add more oxygen to the AFR mix... either by nitrous or forced induction (turbo/super-charger).
