what's better for an s2k? comptech SC, vortech SC, or turbo kit?

 

Depends. Do you do more drag racing? Autocross? Just a daily driver? weekend warrior street racer?

For drag racing, I would suggest a turbo or NO2 over other options. Greatest increase in torque curve is realized with a turbo.

Superchargers are great for daily driving or Autocross/road racing, when your up near redline most of the time.

If you're a street racer, then you should prolly save your money for all the tickets you'll end up with.

If its your daily driver, leave it stock -- you'll realize less financial loss when you try to sell it, and you will keep the rock-solid reliability most people have come to expect from Honda motors.

 

In addition, for Road Racing I would lean towards keeping the car stock for your first season or two but a Supercharger would be the way to go there as well.

Most autocross events will class an FI car Prepared or Modified so I would really think twice before stepping up to that level of competition especially if this is anything resembling a daily driver.

I wouldn't really recommend a Turbo except for drag racing and only if you've got 10g's or more buring a hole in your pocket.

 

it sure burned mine.

 

How is that coming along now? Are you still running the VAFC?

 

Running awesome. Actually, Im running a whole bundle of things, which some may or may not agree with doing.

Im running the HKS FCON in conjunction with the VAFC. So thats two piggybacks. But ..it works. I also got rid of the FMU, and got 550cc injectors. So no lean conditions. Pulled off just a tad under 300 whp @8pounds with 91 octane, and still have a catalytic converter.
pretty darn happy ....

Get the Turbo charger and you gain power.. however lose reliability.... Comptech is more honda friendly (especially since they fixed the bracket).... Vortech more power.. less honda friendly.

 

No issues at low rpm/idle so far?

 

No issues. However, Ulitmate Lurker (who tuned my car) ended up taking out 15% of the fuel @ about 1000RPM because I was running so rich at idle. The computer was trying to compensate and withdrawl 45%of the fuel at idle. So once we adjusted that, everything was okay. No more CEL's.

 

WTF I thought the HKS F-CON was a fully programmable stand alone unit...kinda like the Apexi Power FC?

 

There about 3 versions of the FCON ....the FCON , the FCON S and the FCON V Pro
I have the S. which is pretty much a piggy back ECU, that works off the base maps of your stock ECU.

It does control Fuel/ignition timing, however, the first tuner that I sent it too, was very conservative in teh fuel maps, by running tooooo rich in certain areas. I just fine tuned withthe VAFC and altered the VTEC point.

FCON doesnt have VTEC control, which I still cant understand

 

I think so too!

 

thanks for all the info guys

 

You are using the stock FPR then? Nifty. Where did you get the injectors and did you go high resistance or low resistance? I'm waiting another month or two to get buck wild and crazy with the tuning but I want to pick up the parts now. Tabs are due soon and I've got to go for the old emissions test. I hope the technitians don't recognize the whine...

What was Speedcraft's solution for the ECU freaking out on positive readings from the MAP sensor?

Need a throttle body or an A-Pillar replacement with pods?

UL rocks.

 

Actually, Im using the AEM 1:1 regulator.

what are you worried about?...isnt the comptech smog legal? haha.

I believe the injectors are........I can't remember, Im sorry...all I know is that they are 550cc's peak and hold, and that I had to use a 95 prelude resistor box to have these injectors work.

Speedcrafts solution to the positive readings was to use a missing link valve that bolts under the stock Map sensor. I would rather use the ESM, but hey...it works.

good luck on your project

 

The Comptech is CARB legal and all that, but as a habit I run pretty damn rich. Unfortunately it isn't very evironmentally friendly.

I've seen way too many guys blow engines using forced induction. In fact every single one of my friends that have run or are running FI have blown an engine. So my project is centered on bringing down IAT and smoothing out the fuel curve. The car makes more power than I can dream of using at Autox and its enough to get me into a lot of trouble at the track. (it sure is fun tailgating Corvettes though...)

Whose solution did you go with for the exhaust?

 

I ended up having a custom mandrel bent 3 inch single done.

I really like it. Sounds mean. Almost muscle sounding.
