Hey any of u guys out there that got a tiburon, 97-99 or so that have the zex nitrous kit, how does it work, (good,Bad). Anybody damage there engine from using it? Just asking for some info cause im thinking of ordering on monday, help me out guys what do u think of it personally?
Thanks

 

I have an 01 tibby w/ 75 shot of ZEX... i suggest running ONLY the 55 shot on stock fuel system... i upgraded to a WALBRO 255lph in-tank fuel pump and upped to the 75 shot and no problems, but i use it rarely, my 2 cents: don't get greedy with it... but otherwise, its fun!! read up on nitrous lots, so you know the ins and outs.

i got a 99 tibby
i loved it
I did get some engine damage once because the fuel lines were not clamped in SUPER tight,...
i was running a 75 shot with an eclipse turbo fuel pump

If you get the kit make sure the clamps on the fuel lines are super tight,... i mean super tight

If you go with a 75 shot, get the zex plugs and upgrade your fuel pump like it was stated earlier

Nitrous is fun,... just dont get too happy with it.

 

Ah people, but what about the 65 shot? I havent heard any debate on that? Do you need the pump still for that?

 

if you are using your stock fuel system then you should only use the 55 shot. plus the 55 is straight hook up. if you go 65 or 75 your supposed to retard the timing and all kinds of stuff...i have the 55 on my 99 accent and its great.

 

Its funny how everyone has said this stuff about the fuel pump, but from the most reliable sources I have heard from in the past, the stock fuel pump is good up to 200 hp. So do the math and you actually dont have to upgrade anything. They just dynoed a tib with a 100 shot on it and it wasnt even up to 200hp, think about it!

 

You ever thought that the stock fuel pump might only be good up to 200HP at the CRANK? and not at the wheels? The dyno's on the other post are at the wheels.

This has been discussed several times. Use the search feature.

If you are going to run anything higher than a 55 shot you better buy the walbro pump. Just my 2 cents. *Sorry didn't want to be raggin'*

 

I 've got a question,I have a 2nd gen Tiburon,I have re-programme ECU plus air intakes etc etc etc and now it's about 160hp and i'm thinking of installing zex kit for the begining the 55 shot Will the engine handle the extra power meaning 160+55hp???? Should I change my fuel pump??? I've got a Haltmeter and for now in WOT it's allways rich.What do you think??
Thanks guys i'm looking forward reaching the 215HP!!!!

 

You said that you had a reprogrammed ecu.
... do not use nitrous if your timing was advanced.
