Hmmm. Thanks for ur responses. Here's the answers to your Q's:
Yes I'm practising driving, regardless of mods.

This is the site I went by to get what power I have: http://www.redbook.com.au/vehiclesea...p?key=HOND96AI
You might have to click on the "Specifications" link on the left. Then I just multiplied the 88 kilowatts (kW) by 0.7457 to get 65.6HP. So you guys think that's rubbish to start with? Stupid metric imperial conversions... Many sites gave that ratio is the conversion rate, and I'd have no idea whether that info is accurate, but it's the one I mainly go by for any car.

The exact model of my car is: A 96 FWD Civic CXi 1.6L SOHC non-VTEC Hatchback.
EK1 D16Y4 Australian spec Sedan & Hatchback FWD 88kW/144Nm
( going by this page: http://www.carforumz.net/forum/lofiv...x.php/t44.html )
That's the ONLY Aussie spec civic in that list, and matches my car chassis etc. Only the last number after the Y I am not 100% sure about, but probably makes little difference since we know it's a D16.

Next point: I'm not going to turbo or put in NOS. I'm under 25 and want to still be able to insure my car, the Aussie insurance companies will charge me out the a$$ or not even go near me if I turbo/NOS it. And i really can't be a$$ed taking out parts when I have to go for inspections etc. I want "set and forget" mods. I'm not racing anyway, and like I said, half the aim of this would be for more efficiency.

At the people saying "You only want 10HP??" Of course I'd like more, but discounting turbo and NOS, there's only so much (that I know of) that I could do, considering the engine I think I'm starting with. I've read about boring the throttle body and replacement camshafts and the like, but they seem even more money than my planned mods, with probably even less effect.

I'm at work ATM. I will check that last engine code letter and post it later.
Again, thanks for your replies. Hopefully the extra info will help.
