Hey I was wondering if you can run a water meth injection with a stock ecu? My car is stock except for cai and exhaust, I got a 92 FD. I'm looking to do reliable mods and keeping it twin turbo, thanks..

 

yes.

 

You could, I just don't see any real reason to as its not going to benefit you as greatly as other mods for around the same cost. It would probably be more effective to spend the money on getting an aftermarket ecu of sorts first even for reliability. You can find powerfcs in the for sale section pretty cheap

 

Sweet thanks! I'll buy one soon, I was planning on getting one but just put a new roof on the house so it might have to wait a few weeks haha

 

don't really see a reason to on a stock ECU car, it will help keep carbon away but premixing will also help a bit with that.

if it's a track dedicated car then yes, DD not really.

 

If you hit alot of traffic, water injection does add alot of safety but you really need to get a PFC or something that monitors air intake temps first. I've said this so many times but water injection has been my favorite performance and reliability mod so far. It's worth every penny. If I had to do it all over again, it would be the 3rd thing I put it besides the PFC and the base reliability mods and recalls that have to be done.

 

Which is what I was saying. Theres other mods to be done before the Water/Meth Inj. Aftermarket computer was and will always be my first mod on a FD.

 

Disagree. A simple boost activated system with a properly sized nozzle is still good for reducing temp spiking from periods of hard boost as well as carbon...even on a stock ECU at stock boost levels. If it were really expensive it would be a different story. But simple systems aren't pricey as some reliability mods go and can always be upgraded later.

 

I got blitz cai, HKS inter cooler piping, kakimoto cat back so far
