Waja 1.6(A): Any tips on what else to mod?

[sysh]

.. was just wondering whether anybody here could give me some advice on what else to mod on this rather limited-powered engine of mine. Anything is fine just stop short of transplating another engine (don't plan to go through the hassles of JPJ and might wanna change the car in a few years time). So far what I've done with the engine:

1. K&N Drop-In Air Filter
2. Denso Iridium Spark plugs
3. 4-2-1 extractor + bullet + middle piping + backbox

It's probably not much, but was thinking what else can I do as the car is an automatic (don't plan to change, drive to KL jam everyday lah). Might be a noob at all this, but what about PnP, S-AFC , putting a 4G15 dohc head (how does that work, and what does it do?). Sorry if these questions have been asked repeatedly..

Thanks

go for PnP and balancing.
then maybe a high cam and pulleys.
then got money..get an EMS>

EMS to block the rev and speed cut?

noted.
what does the high / racing cams do to the car anyway.. car's able to rev more freely at higher rpms thus more power?
i do understand that a lightweight pulley would lower the rotating inertia of your car accessories (eg. alternator, water pump, air con and power steering etc) and releases more horsepower as a result, but how much lighter can we go without having to detriment normal driving? don't want these things failing on me.
oh yeah.. does it cost alot too?
