So I have a lot of ideas / mods Im going to do to the engine in my next project.
I just want to know is there anything else, any other mods that can be done.

Basically, these are my plans so far,: (Upgraded/modified)- Intake, Exhaust, Emissions Removal, ECU, Internal Engine Porting.

Some engine details: So far Its a stock S4. I'm planing on using some S5 parts like, rotors, MAF, VDI, and maybe ECU, if I can find them. Cold-air Intake, Full Exhaust, TB mod, Electric Cooling Fan, wideband O2 and ECU upgrade, to monitor/control some things a bit better, like A/F ratio.

I know I could upgrade the fuel, but I might not have to.

Is there anything I can do with the Spark, Oil, Cooling (besides Fan)?

Is there anything else I haven't listed here?
Any little engine Details to increase performance, reliability, etc?

Thanks.
