hi everyone!

my name is mike from new zealand.
i have recently been speaking to a friend of mine reguarding water injection,i currently know very little about it but i am wanting to learn more about it!

i own a turbocharged 1988 honda prelude non vtec and i am still working on the project as i write this and need some info from you guys!

i am on a limited budget here so if you can awncer my questions with that in mind, i will appreciate it greatly!

i will be running:

2 litre twin cam engine
subaru ihi vf10 turbo
megasquirt ecu
2.5 inch exhaust
95-98 octane fuel
12 psi
7100 rpm rev limit

my questions are:

because of my low budget, is it a good idea to inject water into the turbo-as high pressure pumps look rather expensive- or as an alternative, would a 120 psi fuel injection pump work?

i have two pressure swiches that were given to me by a friend, i am unsure of what psi they are rated at but i guess i should have the one i use kick in at around 5psi? also, is there any way to get he swiches tested?

will i need any form of electronic management in my water system or can it just be rigged up so the pump starts when i get above 5 odd psi?

ive been reading about how you guys use a mix of water/methanol or water/alc- is it ok ro run straight water? the reson i ask this is because i want to make a system that i can just top up every time i fill up!

i have downloaded the nozzel calculator, it says i will need a 2.6gph nozzel.
- which is he best place to buy one from online?

any help would be great as i am very new to this phenomenon!

thanks alot!

mike

Hello mike

I know the pumps are expensive but they are designed for this. Fuel pumps are not going to last very long as they can't handle water or methanol and will fail.

As for the pressure switch you can check it with a volt meter. They start at 40ish us and go up. Fluke is a very good brand and is what i have.
I would sujest getting one thats adjustable. Ours is on sale atm.

No, should not need any managment.

Yea, running straight water is fine, you can also run windshield washer fluid, this is a good source of methanol.

I would like to think our store is the best place to buy nozzles. I know we have the best pricing on them.

i agree with Rocket.. the prices are very affordable. I would also recomed going with one of the Devils Own kits so you can have a progressive system.. this is far supersior to the on and off switches

PS.. i run straight denatured alcohol.. works great and easy to find at local hardware stores like Home Depot
