Quickest and cheapest way to get more hp?
First thing you should do, actually, NEED to do is address cooling. Too many things can happen, so play it safe. At Least split the cooling, and maybe get a looped rail, depending on what power your looking for.
But get a hold of Jerry at Eurocharged, he'll take care of you.
- Headers Kleemann 1000 USD
- 82mm TB 1350 USD (Eurocharged, limited offer I believe)
- Fuel Injectors (500 - 800 ) USD
- Water/Methanol kit (400 - 800 ) USD
- Updraded HE (350 - 500 ) USD
You pick what you want

What does that mean? Additional coolers, bigger radiator, pumps, what??
Can someone please explain the cooling system layout to me or is there a website to look it up?
What does split system mean?
I am realy in the dark here - and I don't mean just in Africa :-)

nibo - honestly it all depends on how much you plan on modding your car...
I upgraded my HE and had my pump replaced with the newer Bosch 010 model - and I haven't had any heat-soak issues - but then again, I'm somewhat a mild mod with just the S/C pulley and tune
if you plan on a bigger crank pulley, it's strongly recommended to go with a killer chiller or split the cooling because the larger pulley adds a lot of heat
but even if you're mildly modded - you can do the best cooling mods and it won't hurt a bit
It will take you 30 minutes tops if you don't hit any snags (stuck bolt) and you look over any DIY threads to get tips (one tip I will give you right now is you do not need to unbolt your motor mounts and raise engine to do this like some say, simply lift the radiator support up, lift up on the fan and put an extension and socket through it right on to the bolt of pulley).
If you can swing it, then get a bigger heat exchanger as well, and if you have more in the $1400 range to spend then I would skip the pulley and heat exchanger for now and get headers and a tune instead to have much more consistent power due to not heating up the air more running higher boost pressures from the pulley swap. You will also get better traction and have much less traction control intervention slowing you down from the increased torque real low in the rpms from the pulley. Then get a heat exchanger when you can.
