Wow. You've been getting stuff cheap!
WERD. I guess I'm a pretty thrifty guy! ( or cheap, however you wanna look at it
)
As for turbo kits, you can scoop the GReddy kit for the AP1 for roughly $3,500-$4,500 , depending on shipping costs of course.
Reikoshea's comment about the "tunning" aspect is spot on, but let me clarify a little. Tuning is a loosely used ( and loosely defined ) term now-a-days. Retards consider 'tuning' to be an intake and tail lights, but I suppose you mean actually touching the ECU and doing something mild like higher REV/Speed limiters, better fuel mapping to take advantage of parts like I/H/E...etc. , right? You're not gonna see big gains from mods like these on the S2000 like you would on the D or B series Civic you had, ( pound-for-pound comparison ), unless you back them with big dollars. The F20 in the s2000 is like a mildly built N/A K20, accept it comes from the factory this way. A little higher rpm limit, about 25-45 more crank HP. You can only go so much farther with it....naturally asp. that is. Boost is another story.
Out of everythnig you could do to your car, the first thing you should probally do is mod your driving skills. I'm not saying you can't drive or the car is to much for you, but the s2000 is a whole different animal compared to a civic, and most other cars for that matter. If your gonna play with the car, find a parking lot or a track to do it in/on before you decide to get stupid on the street with it . The s2k can be pretty unpredictable if you are not use to it. Here's a few begginer s2000 tips just for the hell of it;
-Just 'cause it's RWD doesn't make you a drift star, it has a lot of "snap steer", and you will find yourself pointing the opposite direction that you intended if you're not carefull.
-The S2000's diff doesn't like to be abused, which is what Reikoshea was getting at when he said to buy a new differential. The clutch doesn't like 9,000rpm launches either.
-If you can afford it, replace the valve spring retainers/keepers with better ones. They like to fail at high rpm. A loose valve bouncing around a combustion chamber never ends well.
-If you have a plastic rear window, replace the top with the newer glass-windowed unit for gods' sake,YOU can't see through it. Not to mention people don't like to look at that dingy shit. ( this goes for all the Miata owners out there as well )
-Take care of the damn thing. PRODUCTION of the S2000 has stopped and it will probally be worth money one day.
- BUT MOST IMPORTANTLY , 1. top ALWAYS down (More pedal = less wet) 2. Keep the "flash" alive
Good luck with the new car
