Water Injection on a N/A motor - Honda Prelude Forum

borisbecker · 02-02-2008, 10:08 AM

Hi guys,

Is it possible to fit water injection on my normally aspirated H22 motor ?

I have cold air induction ( k&n typhoon ) and was wondering if fitting WI very close to the inlet manifold is possible, and working only when on VTEC ?

What are my options please guys ?
Will I gain performance ?
Will I cause engine damage ?

thanks

It's not Peter. Go look up WI if you don't know what it is.

You can add WI to an N/A motor, but really the benefits will be small. In order to take advantage of it, you really need to tune for it as well, since it will allow you to advance ignition timing.

thanks for the replies, what sort of gains could i expect without the aid of a remap ?

Well sorry ken. I have never even seen this (exception to intercooler systems).

My bad to everyone.

I really don't know, because I've never seen anyone do this without EM. It's really considered an advanced sort of mod; plus it's expensive to do correctly. On the basis of cost, there are far better payoffs for performance.

really, like what out of interest ?

^ Headwork, EMS + tuning, etc

Also water injection is meant for very high compression ratios.

Like everything in here :

N/A Performance Library (README!)

W/I and Nitrous actually have very similar costs and setup requirements. Nitrous gives you way more bang for the buck (obviously). That's the most obvious comparison.

Hondas are much better off starting with I/H/E mods and going from there.

That thread made me laugh...

dvsracergirl · 02-14-2008, 05:23 PM

another BIW thread??

haha

WI is not a feasible mod for a stock motor and no EM!

its a nice thought but cost vs gains is in the red....i would suggest building your engine first
