Does anyone have a direct port system or even a wet system on their Z? Are they are any systems that are more Z friendly than others? Looking for some feedback from nitrous users with a Z.

 

I, like many others on this site, have used a Zex Wet kit for the last 9 months. I've recently switched to a custom kit made by TNT specifically for the 350z ( sent them my throttle body for a couple weeks) and will have install finished this weekend. I'll report back after dyno next week!

 

What hp kit are you running on you're motor?....I read that you were building up you're motor for this purpose. I have purchased an engine from the classifieds on my350z and I am planning to build a dedicated nitrous motor with a direct port wet kit. It seems to be a toss up between NX and Zex for which kits are the most popular.

 

I have NOS wet kit... for know is all good, A++ product!

 

TNT's shot size comes close to the actual RWHP added ie; 150 shot=150 RWHP!! I have jets from 100 to 250! I'll start with 100 and if things look good (A/F) I'll go immediately to 150! I believe the engine is strong enough to hold a 200 RWHP shot, I just don't know if my "b lls" are that big right after my engine rebuild to do it the first day! Should know this Monday or Tuesday!!My Zex kit was putting down 144 to the rear wheels!

 

Does TNT have a web site? I am curious about their system for the direct port wet application.

 

mjedens:

Your kit is a direct port? if not what #'s of jets TNT use for 150 and 100 shot? You have the 144 rwhp for the time you have the other system?

Thanks

www.nitrous-power.com (TNT's Web Site) Please read the description of why their system is different than others! I'm not saying this is better than a "direct port system" but I believe it's the next best thing with their technology of "atomization" of fuel & n20!

Neither the Zex or my new TNT kit are "direct port"! If I was going entirely N20 all the time (track only car), I wouldn't hesitate to go direct. The size of TNT's solenoids along with their technology of mixing fuel & n20 have won me over. I will "spray" for the first time with TNT this coming Tuesday, so stay in touch! The 144 RWHP was on the zex kit with jet sizes 73/40. I'm in St. Louis for Thanksgiving (Mother-In-Law) and do not have TNT's jets with me. I'll try to remember to get back with you.

 

I ask about your jets sizes because I have a friend w a G35 that have the Zex kit and w the 100 shot put only 52 rwhp in the rich condition... I have NOS system and use the same 100 shot (52/28) but mine put 90 rwhp... other thing is that 73/40 is a 240hp shot and you only put 144 rwhp... I just wondering if I put that combo and follow the same pattern my Z is gonna put around 200 rwhp and that is to on the line!
so yes put your car on the dyno and let me know how come that rwhp... oh and let me know the jets #'s for that shots (100 & 150)

Thanks a lot for your help!!!

 

Any Dyno's yet???

 

Dyno showed A/F still too high , between 2900 & 4200 ( high 14's)! Removed ECU & sent it back to Tadashi (TS) yesterday with new A/F charts! I'll get it back tomorrow (Wednesday) and dyno again that evening! TS has the low & high ranges just about correct (low 13's) but above range(2900-4200) is way off! I'll not do a n20 pull until I get the motor pull correct. Dyno on motor still shows RWHP around 292.

 

Very good #'s on N/A... Thanks for the info... please keep up posted with the Dyno w the TNT Kit!

 

......

 

mjedends,

What mods do you have on your car? 292 whp is great for NA; when I get a Z my goal is going to be 300 whp NA and a decent-sized shot of nitrous.

 

Mods= Everything except a S/C !!

 

Any Dynos with the System? What # of jets sizes do TNT have for 150 shot?

 

I am having an issue getting a zex shot using 54fuel/30 n20 tgo get the wheels to stick to the ground. What suspension mods do you have to get the 144rwhp to stick. How do you get that it is a 240-shot? What about your clutch?

I got the ECU back Wednesday morning & dyno'ed that afternoon. The first pull the A/F looked okay between my problem area of 2900 rpm & 4200 rpm- mid 13's! The next three pulls that same area went back to low to high 14's. I'm thinking now that the ECU might be adding some timing after learning I'm giving it "hell"! I'm at a loss on what to do next, can't understand why Tadashi can't flash that particular range with a lot more fuel! Glanced @ TNT's jets, they do not correspond in # size to anything else ( Zex or NOS) so giving you their number size would only be misleading!

Hopefully your #'s are mistyped! N20 should have the larger number - fuel the smaller! I've never stated that a 73/43 is a 240 shot!! All I know is that it puts down 144 rwhp. I have a Spec Stage 3 clutch, Eibach springs, removed front struts, and use MT 26 by 11.5 16" ETs with 9 psi!! All you have to do is leave the line @ 6000 rpm & "hold on" to get a good 60 ft!

 

does removing the front strut bar help out that much??


we should look into that nismo rear diff. thats out. should help on the track.

 

Hold on, there is some conflicting info here - typos perhaps?

For ~144 whp, the jetting used was 73/40. The 73/43 has yet to be dyno proven that I am aware of; only MJ and I have used this combo but we have not proved numbers with it, only with the 73/40.

I don't know where 240 hp came from for a 73/40 jet combo...per ZEX, that was their 200 shot at the crank.

MJ, check your PMs for ECU info.

belerin, check your PMs on G35driver.com. Also, if you are after drag tires for the track only, definately go with the MTs; however, the BFGs make the better dual purpose tire.

I, too, have removed the front sway bar. There is a difference, though slight. I can come out ~500 rpm higher and the front end pop-up effect is pretty cool.
