I honestly think you should go larger with your rear wheels, or get some spacers for them. They just look to small.

 

i agree 100% they are 20's but there not staggered in the back and that drives me crazy, i have been wanting to get spacers for the back wheels but i a worried about them breaking loose, being that they are on the drive wheels. what do you guys think? is it safe for street use? I dont plan on running these wheels at the strip, i will use my stock ones for that. also i have heard that it will throw off suspension dynamics by using spacers, is this true as well?

 

clean ZR. any plans on takin it to the strip?

 

where is your blow down pipe from the bottle??? not safe... tsk tsk

 

i do plan on taking it to the strip, i just installed the utec and all the other mods, i have to wait a couple weeks to save the money to get it tuned for nitrous, and an n/a map done as well. and to johnwigs, yes before i run it on the stip i will have a blow down tube installed as it is regulation. lol. kinda wish they would have included that in the kit.

 

welp my motordyne sticker is in the same exact spot thats weirddddddddddddddddddddd

 

yeah well the strut bar looked naked and seemed like a perfect place for the sticker, i dont want to sticker out the windows or body but since its not an easy mod to show off, i felt the sticker did deserve to be used

 

well here is an update, i got my nitrous bottles filled yesterday and spent the entire day out sweating my a$$ off wiring up the nitrous and window switch nitrous gauge and installing and wiring the purge kit. got it all installed and while i was a pro performance i was persuaded by the guys there to spray it. i had 75 shot jets in. so i got it threw 1st gear and then armed it and hoping the window switch would work floored it, didnt feel anything so while i was there he said take the window switch out of the equation. so i did and then i tried it again, still nothing special i did feel it hit a little but it didnt feel like much at all then i heard a back fire! rolled back to pro performance and he said not to spray again until i get 1 step colder plugs. so i didnt, the back fire was in the exhaust nothing loud or damaging. i think its cause of the tune on my utec was retarding timing way to much to compensate. so i get back to my dads house where i was working on it. i notice that my gauge i installed which i bought from a guy on craigslist but it was obviously new is reading max pressure all the time!!!!!! the mechanical bottle pressure gauge is reading right at 950psi. so that piece of crap isnt working. i turned the bottle off and purged some of the pressure down and guess what now, the dynotune purge i bought from the same craigslist guy is leaking from the purge side of the solenoid. well all the work i did seems like it was for nothing, the window switch i bought new from summit crapped out on me, the gauge and the purge are not working either. before anyone says anything i am really good at wiring and i followed a diagram online showing how to wire the window switch into a 4 point automotive universal relay. to work with a zex wet kit. and there is no way to mis wire the gauge its a positve, negative illumination and the sensor is direct from the mounting location to the gauge. so im at a loss for words at this point. anyway on an upside i did make my own gauge pod out of an unlikely source for my nitrous stuff. i used a dvd case as the panel, it may look a little ghetto to some of you but it gets the job done for alot less than the 35 bucks they want at crawfordz for a peice of abs plastic. lol. you guys wish me luck on getting everything squared away by next thursday, thats when im supposed to get tuned. so i can go to the track next friday!!!!

here are some pics of the dvd gauge/switch panel:

 

sprayed her for the first safe time today with the one step colder plugs and 3 degrees of timing removed across the map, it felt great i will probably spray a few more times at 75 before getting it dyno tuned on the utec in the next week or so

 

well i got the z tuned today on the utec and dyno. we tuned for n/a and for nitrous. im happy with the results. i am picking up my jets for 125 shot tomorrow and will be tuning for that on the 27th. here is my dyno i have 4 runs on there, stock tune is the first one, second is n/a utec tune, 3rd is 75shot, and finally 4th is 100shot. the psi on n2o for the 75 shot was only at about 800, i swapped a fresh bottle in for the 100shot tuning

 

As per NHRA and IHRA rules, you do not need a blow down tube if the bottle is mounted outside the passenger's compartment ie. The trunk in a Roadster. The blow down tube is only mandatory in a hatchback type car where the bottle (if the burst disk gives) will fill up the passenger's compartment with nitrous oxide.

 

Dunno, but I reckon your antenna looks like a sex toy.. nice ride otherwise

 

Nice mods....looks like a fun Z!
Overall how satisfied are you with the Zex kit...?

 

Good point! ZR!
