The very first and simple mod would be the intake part. Remove the drop-in box and lets have fun with open pod intake style. But, make sure to have a Cold-Air-Intake system fitted as well. If you have an extra budget, make a heat shield surrounding the open pod filter to avoid the heat from the engine to disturb the temperature of the air going through the open pod filter. Heat shield is quite expensive to be done though. The next stage is the exit part. The exhaust system. To have a high rev power, go for 4-1 header while for low revs power, go for 4-2-1 header. Choosing exhaust header is not as easy as choosing which Ice-cream to eat. You can go for a custom header but, it will be expensive and you can be sure if the header is effective. Best thing to do is to source a renown brand like Apexi, RS*R, etc. Look for them in "kedai potong" or straight order new unit. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/biggrin.gif"  class="smilie" loading="lazy" alt=":biggrin:" title="Biggrin    :biggrin:" data-shortname=":biggrin:" /> Yeah, they do cost an arm or even leg, but the satisfaction of having something that really improves your engine's power and also owning a branded stuff is priceless. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/biggrin.gif"  class="smilie" loading="lazy" alt=":biggrin:" title="Biggrin    :biggrin:" data-shortname=":biggrin:" />If the car is having Auto tranny, it would be bes to have the rear muffler unit to be an S-flow unit. If the car is bearing manual tranny, go for a straight flow muffler unit like those HKS Hyper Dragger or Apexi N1. The s-flow muffler is to make sure there'll be a little back pressure to the engine so that the engine wont loose its power. This is because the auto tranny were fitted with a torque converter which shifts whenever they wants (no la.. factory spec ratio la.. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/biggrin.gif"  class="smilie" loading="lazy" alt=":biggrin:" title="Biggrin    :biggrin:" data-shortname=":biggrin:" /> ) hence you'll feel the power loss during the shifting. Also the exhaust pipe diameter. For a B20 which having 2.0L displacement, a 2"~2.5" pipe is just a sweet diameter to flow the toxic gases, out through the muffler. Less than 2" will be a choke to the engine to let out the gas. (Even stock pipe is already 2" kan? :hmmmm:)The pipe route is best to follow the stock route. Or, if dont want to follow the stock route, at least dont go under the fuel tank. Dangerous woo.. Lain la kalau full track car, just do side exit without muffler la.. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/laugh.gif"  class="smilie" loading="lazy" alt=":laugh:" title="Laugh    :laugh:" data-shortname=":laugh:" />That's about the bolt on stuff. The internal stuff I dont know much likes, cams, pistons, con rods, injectors, spark plugs etc. Internal stuff are expensive stuffs. Mau ikat perut la macam ni.. hari² makan meggi me la.. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/rofl.gif"  class="smilie" loading="lazy" alt=":rofl:" title="rofl    :rofl:" data-shortname=":rofl:" />Once you step into the internal stuff as I mentioned above, you will need an engine management to manage your engine activity. EMS likes Greddy E-Manage, MOTEC, MicroTech, Haltech, HKS F Con, etc are the types of EMS you should get. Apexi SAFC and other variants of Apexi's EMS, I dont know for sure if they can manage as what E-manage does. This EMS also aint cheap, for E-Manage, the price starts somewhere in the 1K~2K region and upwards. Those Tec-tech ems, lagi la mahal <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/laugh.gif"  class="smilie" loading="lazy" alt=":laugh:" title="Laugh    :laugh:" data-shortname=":laugh:" /> Not to mention on tuning the EMS lagi.. banyak kerja oo.. also banyak duit mau terbang tu.. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/rofl.gif"  class="smilie" loading="lazy" alt=":rofl:" title="rofl    :rofl:" data-shortname=":rofl:" />2) Force FedThis religion (somehow it is.. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/laugh.gif"  class="smilie" loading="lazy" alt=":laugh:" title="Laugh    :laugh:" data-shortname=":laugh:" /> ) is a little bit easy to gather more horses around. FE differentiated by 2 which is Supercharged and Turbocharged. I bet you know these 2 differences aight? <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/biggrin.gif"  class="smilie" loading="lazy" alt=":biggrin:" title="Biggrin    :biggrin:" data-shortname=":biggrin:" /> I'll take you to the world of turbocharged. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/laugh.gif"  class="smilie" loading="lazy" alt=":laugh:" title="Laugh    :laugh:" data-shortname=":laugh:" /> Things that will be "kacau-ed" with your car are the exhaust system and the fueling system, and also internal engine parts. The basic thing that are bolt-ons are the turbo unit, the exhaust manifold which will be fitted to the turbo unit, and the exhaust pipe system. Once that stuff are fitted, your car are turbo-ed edi. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/biggrin.gif"  class="smilie" loading="lazy" alt=":biggrin:" title="Biggrin    :biggrin:" data-shortname=":biggrin:" /> But, cant take it for a ride la.. since you need to adjust the engine compression ratio. As you might have know, to reduce the compression ratio (NA cars comes with high compression ratio, like 10:1, 11:1, 13:1 etc. but force fed cars comes with low compression ratio like 9:1, 8.5:1 etc. ), you'll have to thicken the head gasket (cheap and easy to be done) and also if you have extra budget, look for a turbo pistons. NA pistons are very much different with force fed pistons. This is to reduce to the compression ratio. After done with the compression ratio, you need to adjust the fueling. More air needs more fuel to be spark properly aight? You dont want your engine to starve for fuel. Might end up with blown engine later on. To adjust fueling, change all the stock injectors for more bigger injectors or add extra injectors. Most Ive heard, they'll add extra injectors but with bigger cc. Now, to adjust the fueling, you also need fuel regulator to regulate the amount of fuel to be delivered to the injectors. Also, you'll need a bigger high flow of fuel pump. Hahaha, I really have forgotten to mention these (fuel pump, fuel regulator) things before. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/laugh.gif"  class="smilie" loading="lazy" alt=":laugh:" title="Laugh    :laugh:" data-shortname=":laugh:" /> Fuel pump to pump the fuel la.. By now you should know the logic behind of having high flow fuel pump, fuel regulator, and bigger injectors. Feel scared yet? <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/laugh.gif"  class="smilie" loading="lazy" alt=":laugh:" title="Laugh    :laugh:" data-shortname=":laugh:" /> Those last 3 stuff I mentioned above if you plan to go for big boost like 1.0 bar or more. To be on the safe side, better invest some money for all that 3 stuff. Having low boost, no need to have high flow fuel pump or big ass injectors, just that fuel regulator is a must. Now, since the A/F ratio are corrupted, you need to adjust the ignition la pulak.. this is why EMS are damn important. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/laugh.gif"  class="smilie" loading="lazy" alt=":laugh:" title="Laugh    :laugh:" data-shortname=":laugh:" /> EMS that could adjust the ignition, A/F, etc are best to invest on. Also, you need the boost manager. I forgot the exact name. This thing to prevent boost spike. Invest on these stuff if you would like to go for extreme. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/biggrin.gif"  class="smilie" loading="lazy" alt=":biggrin:" title="Biggrin    :biggrin:" data-shortname=":biggrin:" /> Hopefully all your doubts are answered. <img src="https://zerotohundred.com/forums/styles/default/xenforo/smilies/biggrin.gif"  class="smilie" loading="lazy" alt=":biggrin:" title="Biggrin    :biggrin:" data-shortname=":biggrin:" /> Prices?
