I do engine design for FSAE so I'll throw in a bit more info that may be relevant. Okay, first step I can advise a pair of books that will be very helpful. A Graham Bell's Four Stroke Performance Tuning does a good job of introducing science to engines and engine theory. The book that puts Science with a capital S into engines is Design and Simulation of Four Stroke Engines by Gordon P Blair.
But I'll give you a little primer on this to save you from reading. You can do a lot of nice calculations with intake tuning because speed of sound through air is relatively constant. Selecting exhaust resonances is a bit trickier because of the whole really really hot exhaust gases thing. Blair writes about 15 pages on this, in which he says, "yeah just simulate it". I wound up doing just that with Ricardo Wave and attempting to validate the results back to EGTs but you also have a temperature gradient that changes drastically through the engine cycle.
As far as resonancies, I tuned the intake hoping to see a secondary resonance. I tuned primarily for the third resonance but you can see a secondary resonance in the fourth. So I was looking at a primary resonance around 10500 RPM with a potential secondary resonance in the 8500 range, if memory serves. Deciding which resonances to go after was largely about packaging for us, 1st and 2nd resonances require such short headers we couldn't fit them in a reasonable way.
If you PM me your email address I'll send you a few good papers on organ pipe length resonance.
For aerodynamics competition car aerodynamics by Simon McBeath is good starting point for aero.

For engine design, I've found the tuning books to be good for a base point. The Books by A Graham Bell are good starting points

I'd also recommend some of the books from the speed pro series. Should be noted there are books by bell for 2 stroke engines should that take your fancy
Transmission wise I'm not to sure. I got all my knowledge of those through practical experience and engineering maths.
Hope this helps
Unfair Advantage by Mark Donohue. A fascinating look into what it takes to really and truly excel in the world of racing. Awesome stories.

Forced induction performance tuning. A fairly math heavy book as to how to make boosted engines really work. Unfortunately, it's been discontinued, so it's quite expensive to find a copy. It's really worth paying the money for a used copy if you are going to be doing a big forced induction build.

Four Stroke Performance Tuning. Same author as above. Still in print. Good info about NA engine building.

Street Rotary. A really good intro to rotaries with very solid technical info.

I'd say to keep remembering that what you're trying to set up is a student run business. Pretend you're Elon Musk trying to tell people how electric is the next best thing in the automotive market, which may be true, but the public (and more importantly, endorsers such as the school) are not going to be swayed easily without proof of concept.
Before I go on, I was the president of the VCU FSAE team in Richmond, VA up until last month (June 2017). The team was in the same predicament as yours 10 years ago, and was getting threatened with the discarding of the half-finished vehicle up every other year until our first competition at Lincoln 2017 (for internal combustion). Richmond is the capital of Virginia, so I'm very familiar with the difficulties of building a vehicle in the city as you've described above. That being said, the information I'm providing is from a team that didn't pass the Noise/Kill-Switch tests at tech inspection, and I'm probably going to be one of the least experienced people to respond to this thread.
Start with looking at the paperwork required for competition, particularly the Business Logic Case. Here, you outline your goals for the vehicle and why you want to build it in the first place and who you will sell it to. Do you want to make the car cheap and market it to a broader, lower income market? Or do you want to make a high cost vehicle which comes with options such as paddle shifting, adjustable front and rear wings, and a carbon fiber monocoque. Every design decision that is made on the car after deciding on your market and budget needs to coincide with the Business Logic Case, which you are allowed to modify if the team decides that they want to market differently for whatever reason. The car should be designed around the Business Logic Case, and we messed up by designing our Business Logic Case around the car, and that's why I want to mention this so strongly.
From there, you'll probably want to assign a few people who have taken their economics/business courses to start on the presentation. There are a lot of things in the presentation that the judges love to see, such as factory layouts, tooling requirements, and labor costs that take a lot of time to prepare and assess accurately.
Design work can start alongside the Presentation, beginning with the chassis. There are a few key points I'd like to throw in first:
So as a summary, compile all the paperwork that you'll require for competition, and begin working on it as soon as you can. It should go something in the starting order of:
With all of this completed, you should be able to make a very solid case to anybody at the school for building space. I encourage you to keep trying to get work space as you put together the virtual stuff in the vehicle however.
I will leave these resources as well for you to look through:
Good luck, and let me know if you have any other questions!
Check out these books for in-depth stuff
I personally like Carroll Smith's books and Four Stroke Performance Tuning. While FSPT is very good, it is very difficult to read. Carroll Smith's "_____ to win" books are very good places to start, and are easier to read.
Tuning knowledge is definitely something that is improved on over time. After building fundamentals in tuning particular systems, you'll see opportunities for the car to be better, and then you do research on which setting would be better than another. Racing sims are very good for seeing the effects of suspension tuning, which is where I started. For console, obviously Forza and GT6 are worth looking at. With no console, check out iRacing, Live for Speed (demo has free multiplayer), and Assetto Corsa.
Just a lot of books... Here a re some of the ones I've bought over the past year:
Welding:Principles and Applications (this is a bit overkill but I found it at a used book store)
Advanced Custom Painting Techniques
Four Stroke Performance Tuning
Engine Builders Handbook This is more focused on V8s but has a lot of great advice/best practices.
Sheet Metal Fabrication I have only used the skills in this book to make my electronics box so far, I was originally going to make a cafe style seat but decided on room for a passenger. Someday I would like to make my own gas tank.
Other than that it's a lot of online research!
Four stroke performance tuning
Reasons why:
1)Starts from the basics and continues to the complex
2)Easy to understand
3)Hundreds of illustrations
4)Entertaining
This is definitely in my top 3, the others being Reher-Morrison racing engines championship engine building and Forced induction performance tuning
VWs are a great place to start. Four-stroke performance tuning by A. Graham Bell is an interesting read.

Edit: added link
+1 Kevin Cameron's Sportsbike Performance Handbook is a really good read. A. Graham Bell has written two books on engine tuning (Two-Stroke /Four-Stroke Performance Tuning) which are good companions.
