Modding day--injectors, throttle body coolant bypass, upper radiator hose

Sup guys,

Slowly and steadily the pieces are all falling into place! At this point, I've decided to hold off on installing the supercharger until I get smogged early next year. At this point it's easy enough for me to pop my catalytic converter back on and reflash the ECU with my stock tune. In the meantime, I'll be gathering the rest of my parts and getting ready for my first track day! I figure I should probably learn the limits of the car naturally aspirated before I go bananas with boost and kill myself.

Another thing I'd like to get dialed in before boost is my wheel fitment. Right now I'm running the stock wheels (17x7 front, 17x8.5 rear) with 225/45R17 front and 255/40R17 rear Dunlop ZII tires. The grip is phenomenal, but I'd like to experiment with a "square" tire setup--having the same size tire on all four wheels. This will require two new rear wheels and I'll need them bored out to to fit the larger front hub. I'd run 20mm wheel spacers in the rear to match the front's flushness--all this requires fender work. In the end, it's totally worth it for both cornering grip and braking grip. Without further ado, let's go over the modding day!

Modding day--first valve adjustment and more!

Sup guys,

I've been lagging on posting these photos of a recent modding session with a friend of mine. We put in about 6 hours of work total, and suffice it to say my back was completely obliterated by the end of it. Here's what we accomplished:

My car:

  • Valve adjustment
  • MAP sensor upgrade to 4 bar
  • Slim radiator fan swap
My friend's car:
  • Fan shroud mod to accommodate a 4'' intake tube!
  • Showroom-quality cleaning job
My buddy's car is the silver one while mine is black like my soul. He's working on getting my airbox out here:


You can see just how massive that 4'' intake tube really is in these pics. It goes down behind the radiator fans and ends up under the passenger headlight inside the bumper. After swapping his slim fan over to my car, we had to actually chop a couple spokes off the fan shroud to get my stock fan to fit in my friend's car!

Selfie! Yes, I did work as well.

The results of my valve adjustment at 65,000 were typical of most S2000s--all my valves were tight! I couldn't get a single feeler into place. The first thing I noticed after firing my car up afterwards was how loud the valvetrain had become! I'll be doing this every 40,000 miles from now on.

Right now I'm taking care of some maintenance items:

  • Engine oil change
  • Clutch fluid change
  • Transmission fluid change
  • Differential fluid change

Should be pretty easy. After my injectors and clutch, I'll be ready for boost!

Cheers,
