I'm adding a NOS dry-shot kit, JWT upgraded ECU, and NOS controller. Before I install the NOS kit, I'm planning to install some excellent-quality gauges, like GReddy's top-of-the-line 60mm's (Pearl-white w/ green backlight). Should I get a fuel pressure gauge? NO2 pressure gauge? EGT gauge? A/F meter? All of the above? What other hardware do I need to complete the installation of these gauges? Please advise.

 

Fuel Pressure
EGT
Nitrous Pressure

 

With the JWT NOS kit fuel pressure should not be needed.

 

 

I use Autometer gauges and love them...just letting you know.

Which gauges do you have, and why do you love them?

Exhuast gas temperature...

 

Nitrous and Fuel pressure. I love them because they are carbon Fiber and light up. Ohh, they also work.

I'm sorry, but I've been doing some research on these gauges, and most of the sources I've seen suggest I stay away from Autometer, because one simply has to invest in a good gauge to get accurate readings. Someone on this board actually wrote that the Autometer gauges are good for a light show, but that's about it... Most of the suggestions I've seen so far are for GReddy (Tomei) gauges, which are more pricey, but supposed to be top-notch as far as quality/accuracy is concerned.

Anybody else have an opinion here? Thank you.

 

One of the gauges was cheap...I think $20-40, the other one (I think Nitrous) was around $180...if I remember correctly...I should find my receipt. Everyone I know uses Autometer. I have nothing against Greddy except their lack of production speed...I waited forever for my catback...As far as I can tell my gauges are very accurate...

I thought if you were keeping it to a 50 shot or les you dont need gauges?

they were just talking about the Autometer Air/Fuel ratio gauge.....NOT the Fuel Pressure, NOS pressure, EGT....etc...they are all very good gauges.....and in my experience (I have an Autometer A/F) I think it works fine...

 

ALL A/F gauges will be inaccurate for that matter if you don't use another O2 sensor..

 

I thought you could tap into the signal wire from a stock O2 sensor to feed an A/F meter... No? Please advise soonest.

 

I spoke with "Ben" at JWT this evening. I asked which gauges he'd advise with my nitrous oxide installation, which will include a JWT upgraded ECU and nitrous controller daughterboard. Ben suggested only a fuel pressure gauge & a NO2 pressure gauge. He also told me neither an EGT gauge nor an A/F meter would be needed w/ the installation. What do you think about THAT?

 

The JWT set up is only a 65 hp shot I think, and my bet is they set it up rich. What kills me about the JWT nitrous system is that to upgrade the shot level you have to send it back to them to be reprogramed, and at some point you need to upgrade to larger injectors. Their kit uses stock fuel pressure but opens the fuel injectors for a longer time.

IMHO a well equiped NOS dry kit is a better option. You can do 100hp for allot less than a JWT set up at 100hp. $ per HP at the 100hp level, a well equiped NOS dry kit will out perform the JWT kit. The JWT system is ~$900 for the ECU upgrades plus another ~$350 for the nitrous hardware. For 100hp 300zxTT injectors, even used they are ~$50 each. Both systems will need an upgraded fuel pump so thats a wash. Ballpark for a 100hp JWT nitrous system is $1550. You can do a full blown NOS system with, EGT & Fuel Press gauge, gauge pod and bottle heater for under ~$1000.

I think I'm right on this info, if Im wrong on the JWT stuff someone corect me...

 

I placed my order with Cattman today for the JWT upgraded ECU and nitrous-controller. (I also ordered a Cattman/Place CAI.) I already own a brand-new NOS Hardware Kit #05124. While I am tempted to go for a 100-shot system, I have decided to be content with the 65-shot kit. For now, anyway...

With this install, I plan to include a fuel pressure gauge and a nitrous pressure gauge. I may also get a GReddy A/F Meter, if it comes with its own O2 sensor. If it does, I'll install the O2 sensor in the Y-pipe, as you guys suggested. (Good idea.)

Now all I gotta do is figure out where I'm gonna put all those gauges and switches...

You're taking real good care of me, Sprintmax. I appreciate your effort. Thank you.
