Would my car make it across the country twice?

I have a 2016 Honda Civic with 10k Miles on it. The month of April (1-2) I'm going from ny-nj. Then April 3-6 from ny to dc. Then from April 15-17 ny to Chicago. Will my car make it or should I not drive that much in one month?

How to increase your vehicle horsepower?

I have several questions regarding this topic. Here goes

1. What do you need to increase your vehicle horsepower? (I know there's the exhaust system, cold-air intake, manifold, turbo/supercharge) That all I know.

2. How much horsepower will it increase when you install all the stuff to increase your HP? Beside Nitro and Computer chip.

3. This question is regarding question number 2. How much HP will it increase the Honda Civic SI, Subaru BRZ, Toyota 86 (AKA Scion FRZ), all are around 205 HP stock and the last one I'm looking at is the Honda Civic Type R which is stock at 305 HP

Assuming you install twin turbo, after market or performance cold-air intake, manifold, and other stuff excluding the Nitro, and computer chip.

Added (1). Also, I like to know what is a good website to go to look up for all this stuff. I'm not a professional at auto stuff but I always like to drive one that tune-up. Another thing is where do I go to look up for car audio system?

What is a decent down payment for a $25,000 car?

Okay so My dream car is a 2017 Honda Civic si. I've always wanted a si since high school. I'm 20 years old with no credit but my grandpa as always told me if I wanted that car then I need to come up with $2500 and he will let me cosine with him (he has perfect credit). I don't know about you guys but don't you think I need a little more than $2500 since the car is $25,000? And plus I don't want my payments to be like $600 a month, the maximum payment a month I would prefer is $300 but nothing above that. I don't want the car until next summer anyways so I have plenty of time to save up so what do you guys think is a good down payment for that car?

Where do people find their mods for Honda Civics?

I'm helping my friend out because they're new to cars and i personally have a Mustang so i get all my parts from AM or LMR and i went to go help my friend look through website but i can't find any. It appears that anytime i try to look for parts just by the google search bar the most common thing that pops up is either ebay or amazon. I'm trying to get legit parts from professionals who know what they're doing i.e American Muscle for Mustangs. If anyone knows any website for civics please let me know. Thanks in advance!
