NOS on a L28

Excuse me for posting this forum, but it seemes to get the most hits.

 

I have a 1980 280ZX AT that has a good engine, 180# on all cyl & drives straight down the road.

It is a fairly solid car, no holes in the floor, but looks bad do to the rust seen on a walk around.

Nobody seemes to want it, so I am thinking of adding NOS for something different to do & a sleeper.

 

I would apperecate a place for info & a sorce for the parts needed.

 

Does anybody have a setup that I can get cheap? I have a Very Low buget for this project?

 

I read that NOS is only used at WOT. Can the the TPS be used?

A wet kit is recomended. Is wet, NOS & extra fuel?

 

Can NOS be used during launch or only when up to speed?

 

Will the AT stand a 75 to 100 shot?

 

Does anybody want a complete 80 280ZX with a good red interior?

Everthing seemes to work, even the AC. $500 OBO.

I live near Fort Dodge Iowa.

 

TIA Lee Smith

Aye, but I think it gets the least response on 6 cylinder questions. (With the exception of the GN)

 

This probably would have been a better question for the 6 cylinder tech board or the fuel delivery board.

 

If you have a "very low budget" then I dont think you are going to get very much of a NOS setup. Perhaps if you define your budget a little better we can give you an idea of what you might be able to do.

 

As far as I know, NOS can be used at any RPM or throttle position if you have the right system.

 

I dunno if NOS would be a good idea on a car that has not been taken care of very well though. How many miles are on the engine? Ever rebuilt? Any other mods?

NOS makes 6 cylinder setups and they sell easy opening (ie slow opening)

solenoids for gentle addition of N2O so you arent hammering your equipment ZEX has fuel/nitrous controllers that will work part throttle but the cheap systems are all for WOT

BTW the car doesen't backfire any does it that would be a fatal combination for the motor (N2O + pop = KABOOM)

It seems that NX( http://www.nitrousexpress.com/welcome.htm ) is making better systems than NOS. ZEX is one of the newer companies out there.

 

I remember reading that the stock L28 rods could take up to a 100 shot. You would probably need to run higher octane gas to run that big a shot.

 

Nitrous is usually only used at WOT and you can use a TPS if they have one for the Z application you will more likely wind up using a microswitch.

 

A wet system is nitrous and fuel coming from a fogger system. A dry setup would use your injectors for the fuel enrichement and a fogger for the nitrous. The added benifit of a wet system is the extra torque.

 

You could use it at launch, but only if you have a higher stall converter because hitting it to low would probably hurt your rods. The rule of thumb is no lower than 3000 rpms and no more than 15 seconds at a time.

 

Hope it helps.

Thanks all for the info.

 

I was thinking that NOS would be cheaper & easer then doing a turbo or V8 swap

 

I don't need a T/V8 for daily driving, but the extra power would be nice at times.

 

Low buget. I am wanting to find used instead of new.

Most used, but good parts, are at least 1/2 of new.

I see alot of kits for sale at the LS1 sites( http://www.ls1.com/forums/index.html and http://www.ls1tech.com/ ) under the parts for sale section. You would be able to piece most of the kit together using some of the items that are up for sale. Bottle, bottle warmer, fuel lines, purge kits, foggers etc. In fact you could try looking in all the car forums that you know of and look at the parts for sale section and pretty much find everything you need. Check the NX website and get the part numbers needed to build the import EFI kit.

All I can say is that N02 is just very cold compressed 02. Just make sure you get your 02 ratios right , whether that is by an 02 meter or an EGT.If you go to lean on nitrous bad things will happen to your motor.Make sure you have the appropriate fuel presure for your kit,I would suggest a rev limitor that is not a fuel cut (nitrous motors rev VERY FAST). Possibly a set of rpm switches and a full throttle switch and if your car is a stick a clutch switch.There is more to a nitrous system that just a bottle and a button.I ran a 120 shot to the wheels on a junkyard parts bottom end with turbo main cap bolts and arp rod bolts, I put about 80 10pound bottles of N20 through it tthen gave it to a friend who rebuilt it and runs it as a daily driver in his 240z. L-28`s are tough
