I'm getting my Zex system with a 55 hp shot put in next Saturday...and I purchased a used 2.5 GT EJ25 engine for $1600...I will take it to the same speed shop so they can bore it/port it, raise the comnpression to 11 to 1, put bigger pistons (JE pistons for NOS setups) ... all in all I'll be shelling out $5,000 to $6,000...The results will be 265 hp from a naturally apsirated EJ25 engine with Cobb tunings cool air intake, heads, and cams...MRT stainless steel headers on back exhaust system...I'll be also upgrading the ZEX nitrous to a 75 hp shot even thoung the engine should be able to handle a 150 hp shot!!! So the ace up my sleeve will give me a 350 hp "who you mad at!!" advantage over a lot of people!!! Just my $.02...All I need now is to find a better fuel system and ignition system-though I have alreay upgraded my wires to magnecor and plugs to NGK...Oh I forgot to mention, the engine I have currently will be swapped with the one above...i.e. leaving me a spare to do future insane tuning plans- I'm thinking about boring more, porting more, raising to compression more, a bigger nitrous system, and a killer turbo...we'll see!!!

...makes people wonder how I got my name,

CRAZY KEN

I can already see the chunks of aluminum flying through your hood...

One problem you are going to encounter is how to get the nitrous evenly distributed to all 4 cylinders. I had a ZEX kit for a while, ended up selling it because it was nothing but problems. All of the nitrous will flow into the rear driver's side cylinder. What you need for the kind of power you are looking to make is a system with a fogger for each runner in the intake manifold, and then you have to do some drilling and tapping to install them. It's not as easy as it seems, trust me.

Oh, and did I mention that I completely melted the spark plug in the rear driver's side cylinder? I am not joking, it was completely toasted, even the ceramic on the other side of the threads from the chamber was completely blackened. The other plugs were relatively okay. And that was only with the 65-shot!

hEY dIG dUG,

I am already aware of that...that is why I'm using a 55 shot...I'm not dragging with it...just using in as an ace up my sleeve...my replacement engine will be built for a NOS application and direct port was what the shop recommended for a safe/iron clad system...dry or wet(i.e. spray in the fuel line) is not the safest, ONLY DIRECT PORT!!! But that equals more money, which is no problem for people who are CRAZY like me!!! hehehehe

Let me get this straight your gonna raise your compression to 11:1 and then run a higher shot of nitrous. i dont want to be in your car when you run that after a couple of times. Ive been in one car on NOS that blew it was not a nice experience. Dont get me wrong the JE pistons are strong as i dont know what but your getting the wrong ones for your application. Get the low compression pistons if you want to run nitrous. It so much better. That way you could run a 200 shot if you wanted and there would be no problem. Think of the HP you would have with that shot. Also if you ever decided to go turbo you would already have the setup to run 20+ PSI. Like the other guy said if your gonna run nitrous seriouly go with the fogger it might not seem as safe as the ZEX but if you install right youll be fine.

dude....

A wet setup is not when you spray nitrous into the fuel line. It is when additional fuel is sprayed, WITH the nitrous, into your intake.
Sounds like you need to talk to your shop a little more and make sure they know what they are doing!

I don't consider a NOS'd motor to be NA. Where did you get the 265hp figure?

Good luck,

Aaron

Just a word of advice. Don't put mods after your name. The Scooby gods don't seem to like that

Question

If Nos is so dangerous on Scoobies, shouldn't my car have detonated and blew up by now? I am running a 60 shot with 5psi of non-intercooled boost. I have been doing this for the last 40k miles with a 9:7.1 compression ratio (I think this is right). Can someone explain why my engine haven't gone to the boost Gods YET?

Please, don't take this as me sounding cocky or anything. It's just that based on what most people are saying on this board about Nos, theoretically I should have a new engine on my car. And you all know I use the Nos every chance I get. (Please no references to me being crazy. I know I have noodles loose somewhere for even doing this..heheh).
