Default '00RS + Pro ECM + dry NOS?

....with CAI, Borla header, A'pexi muffler...Stock internals?

Upgraded fuel pump & colder plugs enough? Need RRFPR? Injectors?

I had my recal done, but they just changed the O2 sensor- the ECU is untouched except for the Pro ECM I installed. My car has always run rich with the CAI and the header.

Any info, opinions, or advice welcome! Thanks!

I used a ZEX dry kit on stock internals (well, mild cams) with all the bolt ons and no tuning of any kind. It worked perfectly except for a badly slipping stock clutch (55 shot was used). I reccomend you change your clutch if you want to actually feel the nitrous at all (depending on what shot you use and how old you clutch is). I also ordered an upgraded fuel pump as well which was in use with the dry kit. Colder plugs are a good idea as well, I did that too. Get a bottle warmer!

Thanks for the replys!

---So, you all think there is ZERO chance of engine damage with just a 35 shot on the Pro ECM's timing advance if I run 91 octane?

---Will the stock fuel regulator mind the bigger fuel pump?

---Bottle warmer, eh? Doesn't that just increase the pressure in the bottle? Wouldn't a bigger jet do the same thing? Or am I missing the point?

Warmers scare the pajezus out of me after seeing what happened to that NX Maxima. (and the garage/house)
I know, he left the warmer on overnight like an idiot.

Thanks again guys.

IIRC bottle warmer is to keep the pressure of hte NAWZ constant so you don't loose power with each shot.

Igg said it well, your shots will stay stronger for longer! Heat=expansion.

I believe the guy who blew his car up did not have a safety release valve on the nitrous bottle (this is a safety device, if the bottle were to blow, it goes out of one hole and not blow up the whole bottle). But anyway, dont worry about it, just keep it in mind when you have it on.

-I will never say a 0 chance of anything happening, I have had everything go wrong on my car.

-I think you will be ok with an upgraded fuel pump, just dont get a fuel pump designed for 400 hp cars, just a moderate upgrade.

Good Luck!

Dan

i'm considering also running the same shot, with practically the same mods including the pro ecm...

which flavor (size) fuel pump would you guys recommend?

I'd recomend taking the big subs and light tubes off your car.
That crap gives Imprezas a bad image.

Well, I just got the answer from Zex.

He said the 55 shot is fine for the car WITH NO chip or any other type of device that will advance timing past the stock base map.

To use the 65 or 75 jets will require some type of device that will retard timing, like an MSD box or such.

But again, NO spray with the ProECM, which is probably why they are coming out with a new N20 ProECM.

I think the proECM will keep timing from getting out of control... it does it with a turbo, why not NO2?

Somebody didn't get on the GB we just had because he said he was waiting for ProECM to release the "NOS version"

I'm guessing this version will slam the ECU's timing map to zero degrees or at least retard the timing when the NOS is armed.

Actually Rob, the ProECM will likely advance timing when the N2O is being injected... remember, its coolant temp dependent and N2O will cool the combustion chamber.

Andrew, a RRFPR will do you no good as there is no manifold pressure increase. Your stock FPR or an SVX FPR will be fine. A WRX pump will probably work very well for you, but w/ the ProECM you'll be risking det w/o some kind of retard. Colder plugs might do the trick though, but I warn you to stay away from the 2 degree colder (NGK 8's) they aren't rated for the stock coil/wire combo and the car will run like CRAP, if at all, when off the bottle.

Thanks for the info, Bill. A few more questions:
-What plugs would you recomend for general use, (now) and for use on the bottle? (then)

-Would the WRX fuel pump pose any problems when off of the bottle?

-Does the pressure go up with that pump, or just the flow?

Thanks again, Andy

I'd run copper NGK 7's and play around with the gap to get good on and off bottle performance. As for the pump, I don't have a fuel pressure gauge but I did run around with it in my car for a month or two before the turbo and noticed NO ill effects... in fact I think it gave me a few ponies. I'd bet the pressure is increased but by how much I cannot say.
