I just got my comptech S/C today and its getting installed tomorrow, i should have the car early next week (clutch is being installed at the same time) the quality of everything in the package is very high, packaged well and looks amazing. so exited.

 

I finally made my decision. I bought a comptech kit w/ AC.

hoepfully I made the right choice. I dont' plan on going for huge power. And I want to stay away from standalones. So I think I made the rigth choice.

 

you'll like the comptech unit.

 

I honestly don't think you could have gone wrong with either choice. I have Comptech, damned glad I went FI. I'd be equally happy with Vortech based on what I know from a few folks. Good luck!

 

The 06 cannot be retro-fitted with an 00-05 ECU. The connectors are different for one and not to mention you wont have any throttle control.

 

We were talking about an 04-05 UK car, so I think the 02-03 ECU will fit.
I don't really know though; The UK cars might have different connectors than the US cars. Do you know if they're the same?

 

GPW JDM one is out its not in good enough condition.

I've decide to go with a UK02-04 AP1 - so in theory I can just bolt on a Vortech pack. This allows me maximum flexiblity to upgrade.

Would the difference on RON rating of UK petrol (98) to US Petrol (96?) cause a problem with the fueling or timing correction on the Vortech system do you think? I presumed the Honda ECU & knock sensor would just adjust it?

 

It is odd, but I've never seen an S2000 that didn't at least *appear* to be in excellent condition.

I'm not sure about the ECU pulling timing if the RON is a little low. It seems to me that the ECU has to pull timing in response to knock, and then return to the baseline timing slowly and after a delay, but it has been suggested that the ECU may actually "ride" the knock sensor, and that's something I'd want to avoid. There may also be issues with the knock sensor and the noise the supercharger makes. It seems to me that if the ECU worked the way I though it did and the supercharger didn't interfer with the knock sensor Vortech wouldn't have to use their black box to pull timing. LOL, a week ago I was convinced that the ECU worked in a way that prevents lower octane fuel from doing any damage, but because of this thread I now have serious doubts.
The guys who have a better grasp of the details of the ECU programming need to fill us both in on the details.

One thing you might want to consider, given the fuel you'll be using, is that effective compression ratio goes up as boost is increased. Since the Comptech SC has a little less boost, the effective compression ratio is lower so it might be more tolerant of lower octane fuels.

Have you asked on the UK forum to see if anyone in the UK is running a Vortech or Comptech setup?

 

I have the same concerns on the knock sensor/ECU/timing.

Comptech is the "safer" route I agree.

No experience in the UK on this only a 3 SC cars I know of in the UK

Some feedback highlighting the concerns I've posted here

 

Here's another point to rattle your brain:

The Vortech incorporates a "timing box".
