SCvortech

I have a Stock Vortech setup in my S2000 Im looking to get a little more power from it! I want to add some larger injectors im sure the stock ones are close to being maxed ou and I dont want a lean condtion! Will a stock ECU run 440cc injectors? If not waht route would I want to go? Im also thinking of a smaller pulley! What the PSI of the stock Vorteck kits? 5PSI is what I have been told! Whats a safe PSI for these motors? thanks for all you help!! I did a search but im looking to see if there is any new information!

Injectors won't give you more power. The smaller pulley will. To support more fuel you'll need the bigger injectors and some engine management to drive them.

I'm sure you read all that in your search results and I guess you're hoping someone will say something different. Sorry to disappoint.

Moving this to F.I.

The PCM WILL NOT Correct for the 440's on it's own. Some type of fuel management will be needed. An E-manage is the cheapest way to get away with it.

will a VAFC tunned control the injectors?

Arrrgggghhhhh!

Short answer = No, A VAFC is not gonna cut it. You won't be able to directly increase fuel at the injectors, unlike the E-manage.

This has been covered on so many threads I can't even remember. Usually ending up with Honda9krpm being unreasonable and the thread gets locked.

The E-manage is pretty much MINIMUM for controlling big injectors and ditching the FMU.

Trust me, that ain't likely to happen again for a while.

This is bad news for me, I bought the vafc for the sole reason of tweaking my fuel curve. I used a Safc II on my S14 w/ sr20det and it was able to handel 550cc injectors on my 300+hp 240sx no problem and I dont see why the vafcII would not be able to also. The Safc was the ONLY tuning device I used and I just purchased a VAFC for the very same reason, what am I getting confused here?
