nitrous on a stock motor

[audiomaster1990]

ok, so iv been doin my research, and it looks to me like my car would be able to handle a 50-shot of nitrous, but im worried about my fuel/air mixture ratios, and if i use a wet shot would the ratios stay good? im definately goin to hook up a fuel mixture gauge, but im wonderin whether i should add larger injectors??? im also lookin at investing in a high flow fuel rail from venom.

ne more upgrade suggestions would be great.

Why don't you get more reliable HP like intake, exhaust,K and N air filter and the list goes on instead of NOS. Nos you will have to fill the bottle and only use it once in a while unless you have the money too fill it all the time???

Excellent idea man. My car LOVES nitrous. If I were you I'd get a wideband O2 first before you start adding other stuff. That way you know exactly what your working with. First sign of trouble you can back off and there's no guessing weather or not you have a safe mixture. And yes a wet kit is the only way to go in my opinion. Unless you go direct port which of course is also injecting both fuel and nitrous at the same time.

I'm glad you did your homework on nitrous and decided to go with it. So many people on this forum know nothing about nitrous, so when the topic comes up they spew out whatever false nonsense they heard last. So as you know, the 2 most common failures from nitrous are the head gasket and the piston rings. Depending on your goals you may wanna invest in your motor first.

What are your future plans for the car? How much power do you wanna make? How much money do you wanna invest? And what's the car being used for?

You should call Holeshot Performance in Arizona. Their success with nitrous on DSM platforms is legendary. They have a 2G turbo FWD car that runs mid 10's with nothing more than nitrous, intercooler pipes, and exhaust. Of course they built the bottom end to handle it along with the fuel system but aside from that, everything else is stock. Stock turbo, stock boost, stock ECU, stock MAS, stock everything. No huge laggy turbo, no duel wastegates, and no nonsense.

Good luck man. Keep us posted. I'll be happy to help out with anything I can.

as far as pistons go, iv seen some bada$$ domed wiseco pistons for cheap, but im not sure if my motor could take the increased compression as well as the nitrous shot

Follow the upgrade path for the way to go. Also, most "high flow" rails are the same if not smaller ID of the stock rail. Just FYI.

Another thing, all that you listed is for a 4G63T engine, not the 420A which is a completly different engine.

a 93 n/t has a 4g63 engine...

Thank you. Ya beat me to it. And the differences between the N/A 4G63 and 4G63T are very minimal. No oil squirters in the N/A motor and higher compression pistons of course.

Audiomaster. As long as you put those Wiseco's in with a MLS head gasket and ARP head studs you'll be good to go. Make sure you mention to the engine builder that you plan to run nitrous so he can gap your new rings appropriately for you.

As long as you make the appropriate adjustments you can run a WAY bigger shot. I'm running a 150 shot right now. I've seen Holeshot Performance run well over 200 shot. But like I mentioned earlier. The bottom end is built to handle it, and so is the fuel system. The last thing you want when your trying to go big is to run outta fuel. Weather it's nitrous or boost it's a bad thing. So set yourself a goal and build accordingly.

Follow the upgrade path for the way to go.

When you say follow "The upgrade path" what do you mean? What is "The" upgrade path? I followed the upgrade path that my fellow DSMers told me to follow, and now that I know about cars, I wish I wouldn't have done that. For me the correct upgrade path is probably a lot different from some other people. So maybe you could emphasize on that.

My advise on upgrade path is buy the cheapest bolt ons you can find if your first starting out. Because when you want bigger power your gunna have to replace it all any way. If you've been around for a while and understand cars and understand your performance goals, I advise buying quality instead. Simply because you more than likely won't be upgrading it again a second time. That way your pile of unused parts that're collecting dust in the garage doesn't represent a huge wasted investment.

If I'm upgrading to a 37R i'd rather see a $100 ebay manifold collecting dust than a $600 DNP manifold collecting dust. But that's 1 man's opinion.

i wouldnt waste your cash on NOS, the engine wouldnt last long and the price you pay for the system you could put towards a 4g63t engine and make more power than NOS and it would be way more reliable and coverting the car to turbo isnt hard to do thats if your chasis is worth it.

THERE IS PLENTY OF GUYS ON HERE THAT YOU COULD BUY THE PARTS TO DO THE SWAP!!!

 

[Scuba_Steve]

You know, that is the exact mindset mentioned earlier. Using NOS is no different than running boost, its a method to add oxygen to the engine. That is if it's done properly. In fact the nitrogen acts as a cooling agent making it safer.

i think you mean the evaporation of n2o liquid to a gas absorbs heat, cooling the intake charge. nitrogen by itself doesn't cool anything, its the phase change that causes cooling....ok thats enough chemistry for today.

When made into liquid Nitrogen it can definitely cool stuff. That is what they use in Cryogenic labs to freeze people for hundreds of years hahaha.

But what you said is true also. The change from a HIGH pressure to a low pressure will cause a cooling affect.

If I dipped your hand in liquid nitrogen for 30 seconds then pulled it out I could tap it with a hammer and you hand would shatter like glass.

or you could run higher boost with water jets, and save $$$ from expensive nitrous bottles....
