Felt a little bit torquier to me [I had RB header/presilencer and a good condition stock catback, switched to this]
Usually this catback goes for ~$300 used. [If you can find one]
I'm not sure about torque, but I was told by an older guy who races FBs with his son, that a light flywheel will make a big difference in how the car feels.
..Other than those - get suspension and go fast around the corners ^_-

A. Sell your car and buy a Turbo II.
B. Assuming they are still available after the disaster, a J-Spec engine conversion is the next cheapest way to make more torque.
Contrary to popular belief:
- Turbos make torque.
- Turbos are a type of supercharger ("turbo" is short for the word "turbosupercharger").
- Belt-driven superchargers tend to be rather complicated and expensive.
A light flywheel will make the car feel like it has less torque on a standing start.

T2 Duo!

There has been an FC for sale on craigslist in my area for years. It is an unfinished supercharger project. No idea what happened, but he didn't finish it and no one will buy it. And he is selling it cheap. While I don't know the details, supercharging may not be the way to go.
As stated before, best bang for buck would be a T2 swap. Or stay na and port with exhaust, flywheel and tuning.
If I had an na, I'd go carb and clean up the rats nests. Don't be hatin. I love carbs. All 4 of them seem to work excellent on my ninja!

you can do what i did. but not make the same mistakes, lol.
i took a stock n/a block and ported the lower intake of a TII to match the ports on my 6 port motor and pretty much transferred all TII parts into my car......i mean everything. i used a chipped ecu with an added 40 hp and cranked the boost up to 16 lbs with a manual boost controller. just make sure you use the correct TII wire harness for your series car (s4/s5).
aaron cake has a great tutorial about how to do this without using TII parts:

* I use the term "light" and "heavy" in quotes because it is actually the inertia that affects the feel of the flywheel. The inertia is affected by both the static weight and the weight distribution, so with the proper design it is actually possible to have a heavier flywheel with less inertia than a lighter flywheel. Therefore, the flywheel terms of "light" and "heavy" are actually misnomers.
Turbosupercharger and centrifugal supercharger power bands tend to be more exponential. A typical Roots power band is fairly linear until it runs out of steam and drops off near redline. A Lysholm (twin screw) power band is usually pretty linear across the board.

yes there are small differences between the S/Cs but their boost gains are based on rpm and rpm rises at a liner rate.
turbo's boost gains are based on CFM. for each CFM burned they move ~1.7x more CFM.

the M90 is commonly found on ford thunderbird supercoupes which is a 3.8L V6 and should be appropriately sized to make slightly over 200WHP with the proper fuel modifications. but i'm going a step further and keeping the 550WHP capable turbo on the car which is where it may start getting a little hazey as to what to expect from just tossing on the supercharger by itself.
the example should be good for people who want to attempt it though, as those superchargers aren't too difficult to find or very expensive.
it requires a standalone EMS and at least a turbo fuel system to start with, which is where the expenses really come in.
here is the build thread for those who are interested in following it, updates will be a little slow for the next month or 2 though while i work on the 6 or so rebuilds i have in the shop.

Turbos work on mass airflow (lbs/min) as opposed to volume airflow (cfm). The old compressor maps that used cfm were dumbed-down for the hotrodders of yesteryear who had a very limited engineering education and were accustomed to the carb cfm ratings.
