Here's a link to the banjo bolt DIY thread:

EDIT: FWIW, I did upgrade my banjo bolts before installing the SC/AC, just for "peace of mind."

 

The banjo bolt supplies oil to the banjo that feeds the "squirter," and holds the banjo in place. The reason the banjo is called a "banjo" is because that's what it looks like (sort of). The banjo bolt is called a "banjo bolt" because it's the bolt that holds the banjo in place. Banjo bolts (in general) are hollow and have crosswise holes to allow fluids to pass throught them and into a banjo fitting.

Here's a picture of a generic banjo (but it's not exactly like the ones used in our engines):

 

every car is different. some may run fine with same mods as a car that doesn't. The reason they say it it was the banjo bolts that caused the failure was the reason that the number 4 cylinder was scored. If you have done any research, there has been many and i mean many people who have had the number 4 cyl failure, due to the banjo bolts. In europe the bolts were recalled, but they said the reason is they drive the car harder in europe. lol pretty funny right

 

I've had my Comptech S/C for close to two years now, and haven't run into any reliablity issues or problems with the kit. The car has been as reliable since the day I bought her new. Installed it myself at 40K miles, and today I'm at 76K miles.

Just keep up on your regular maintenance and you'll be fine. Also, there's no need for a "tougher" bottom end or a standalone (like the EMS). The Comptech kit is perfectly fine as "bolt on and go" mod.

^^ That's consistent with the experience of the VAST majority of people who have supercharged their S2000's using either a Vortech or Comptech kit.

 

so what are you numbers on the dyno then, w/o ems or vafc?

 

Early AP1's (MY00-01) like mine typically make around 287 WHP on the dyno, and my car is typical. I haven't had the car on a dyno; We measure performance using three axis accelerometers, so I prefer not to make direct comparisons. With the CTSC/AC MY00-01 cars make between 270 and 290 WHP while MY02-03 cars make a little more (280-300 seems to be typical). With the Vortech you get a little more with either car because the boost is a little higher. Stock injectors are good for about 320 WHP if you want to mess with pully upgrades and tuning. I don't know if that can be improved upon with an EMS or VAFC, because that's already pusing the stock injectors.

 

The first obstacle in the boost addiction you'll encounter is maxing out the stock injectors. As RedMX5 said, you'll max the injectors out at 320 rwhp or 7psi.

If you boost past these numbers, you got have no choice but to get bigger injectors and something to run them as the stock ECU will not.

 

Just out of curiousity, where did you come to this conclusion? Is this a personal observation or was there a thread that discussed this specific topic?

Never knew 02-03's push out a few ponies more than the previous years. Glad I have an 02
