I had told a friend that I had considered using a ZEX and he said to stay away from it. He is part of a Chevy car club and told me that several people have blown thier engines using the kit. Then again these are Cavalier, Sunfires and other J-body cars. Don't know what the circumstances were behind those stories though.
Prior to that I have never heard anything but praise about the kits.
Maurice,before I rant this is not directed at you buddy and is just stuff I hear and see daily ok? so please dont take it personal ,your post was just a good lead in to what is bugging me and this does not reflect on anyone on this board this is stuff I see local to me and please dont be taken back by the tone of this post but it must be said. I hear these second hand stories all the time and in every instance that I have seen it happen first hand it usually starts with a phone call that goes like this:
blown motor guy: dave I think I f%cked up something while spraying.
me: sorry to hear it, how much were you spraying?
blown motor guy: 100 shot
me: dont you have a unbuilt stock motor?
blown motor guy: yeah but I was spraying 50-75 no problem and didnt think 25 more was a big deal
me: wet or dry?
blown motor guy: dry
me : you dumb a$$, whats your major malfunction spraying 100 on a 2.0 dry without putting safety features inplace and stablizing your fuel delivery to handle it never mind beefed up internals
blown motor guy: uh well I dunno guess I wasnt thinking.
me: no sh%t! sucks to be you, I will come over and take a look.
I take a look and it has crappy wiring(not big enough gauge for amp draw), no safety devices(wot switch only no fpss or prep work that is bare minimal) and the shot is to big and they have done no maintainence since install(I dont even have to open a selonoid to see it has never been apart since install). so I say who the H33L did this install the three stooges? lets see how bad it is and access the damage.
Now the moral here is very simple: Everyone that goes F/I seems to worry about fuel and timing and compression or leakdown test before install, that all seems to be an afterthought with NOS. if people would pay half the attention to detail setting up the spray and do it up right these moronic now becoming urban legend storys would dissipate and then go away aside from a few where their was truly a bad componant on the motor or kit that gave up the ghost or a defective safety part that was not bench tested before install. BENCH TEST YOUR KIT RIGHT OUT OF THE WRAP BEFORE YOU INSTALL IT, dont assume your FPSS is set at the correct value TEST IT. but as long as the NOS guys market the product as the cheapest power adder to be had it will continue to be cheap going in and expensive coming out never to return to using it again but happy to tell everyone how nitrous cost them a motor because it saves alot of face to blame it on NOS and not poor setup,lack of maintenence and being to cheap to buy some add on devices or worse yet have them and feel it is to much trouble to put them inplace
rant mode off
Have a very nice F/I or NOS day folks....I know I will
Best Regards David
PS My phone demeanor expressed here is reserved for people I consider friends(that have done something very stupid) and not indicitive of my general demeanor, many on this board know I will happily bend over backwards to help them out with a friendly glad to help additude. PIC included showing what I consider a bare bones system I just built including purge, Rpm window and FPSS and WOT micro switch. it should have a second nitrous selonoid for a total of four. 2 nos 1 to bump fuel one for purge but the guy did not want to spend the extra cash and opted for purge instead of reduntant nos... sigh
