mabey a old subject...but..,.... yes..yess.yesss..i know people have alot of diffrences on nos, from what i have heard it can be very dang. on these engines. i know what nos does, but i havent ever seen or/ driven a car with it. has anyone done this? or is it wast of money,and/or reliable? its been picking at me for a while.

uhhh typo..maybe a old subject

a 25 or 50 shot using the cold start injector for extra fuel would not be too bad as long as you did not use it all of the time

would you have a meltdown if you used it alot?

On a 30 year old engine....just a matter of time.

yes, but if you where lucky you might only have a leaking head

the guy befoe me went with new jugs and pist. to a 1.9 L i and checking everything and a cleanup on the engine

The hard part is getting an equal shot to all four cylinders thru one throttle body.

getting an equal charge with the new fogger systems for 50 shot or lower is not hard. the funny part is that the fogger systems cool the intake charge to like 50 degrees f below 0. i read some where that the cooling efects of a 50 shot is worth like 15 to 20 hp on its own.

very interesting....

one of our local AX guys here was running NOS is his /4 banger.
got banned by PCA after he started winning ...

they changed the rules on him!

I ran 100 shot through fogger jets with a nitrous controller on a 1776cc VW engine. A real kick, but a lot of stress on the engine. Never broke anything, but the temptation to race on the street is a bit overwhelming.

Here was my theory:

* Use a 6 cylinder distribution block.
* Plumb 4 injectors to the base of each intake.
* Plumb 2 injectors to each side of the fan shroud as it goes to cool the heads.

It's a loose theory based upon a few things:

1. I heard that head temperatures would be the main issue.
2. I saw a car that used nitrous just to cool the intercooler.

I tought that by plumbing nitrous into the cool air stream you would effectively help cool the engine at the same time the nitrous on the inside was heating it up.

so where does the dry ice go again?

Sure... 47 simple steps to nitrous on your 914.

Actually I thought it was quite elementary

Step 1 - Buy the six cylinder system.
Step 2 - Drop a spare pair of intake manifolds off at the machine shop.
Step 3 - Tap the shroud.
Step 4 - Bolt it together.
Step 5 - Enjoy.

buy a mustang or a Z28 for the nos. cheaper than a type 4 engine.

Never had a problem with over-heating...the things to watch out for are a lean condition, and too much nitrous for your crank and other internals. If the engine is built stout, you can get a way with it. You only use it for a few seconds at a time. A nitrous controller makes it adjustable for retarded timing during use, and other variables. I would not run a large amount of nitrous without one.

no2 has come along ways. there are some really high tech equipement now to run this stuff, timed and progressive controlers, staged set ups an such. and all the ingnition control you could imagine. be careful though you can break things with this stuff [pinston rings and lands, cranks crackheads and blow haed gaskets]! and melt down an engine really fast, spark plugs go real regular and pistons.

thanks for all the comments, heres a pic of my motor, took it out and dressing it

Back in the late 70's an Import Shop in Louisville Ky (Stein Automotive) ran a home brewed NO system on a 1.7. I remember something about using a 2nd set of injectors for fueling while on the bottle. Big fun wathcing it on the AX course, LOTS of tire smoke and spins. They claimed to have outrun a 260Z on top end (140MPH+) with this setup.
