our car sucks for moddding. you can get a good 20whp off adding an exhaust and headers to an 80hp honda civic which is huge gains, but it's because the stock exhaust sucks so much. I think the major problem with our car is that it's already a 1.8 180hp naturally aspirated engine. that's pretty damned good for naturally aspirated thats 100hp per liter without a turbo. so it's already engineered really well it's hard to improve upon it, and when you try you get very small results and at a cost such as hydrolock bogging in case of Intake
or added weight in cases of some exhausts. so yeah if you put an Intake
on a different car you can probably get 18 crank hp but on ours realistically 8 crank and 5 wheel. the only way your going to see 300crank hp is going to be a turbo, if you spend a lot of money you might be able to see 200something maybe 240 if you spend a ton, get the tpr cams for 1200 when they come out, bump the compression on the pistons up to 12.5 instead of 11.5, Intake
, headers, kazuma exhaust, and Power FC, port and polish on your heads, but then your at over what you'd pay for a turbo that'd give you more the tally on these naturally aspirated items is around 5k or more. Nitrous is a good cheap option for a lot of extra HP and it'll give you about the same HP gains as a stage 1 turbo safely, so your right in the nitrous department I think, you can deffinately hit a pretty high crank hp mark with some nitrous, but it's only fun for drag racing 'cause you can't be spraying all the time unless you've got like a 100lb nos tank filling up your back seats and trunk.
