I'm putting in a TII motor into my vert , the engine has 84k on it and it ran fine before being taken out about a week ago. I have yet to inspect the injectors but I was thinking of just replacing them , a friend mentioned www.racetronix.com , considering they have pretty cheap new injectors and they are name brand (siemens and delphi). Should I replace them or not bother and just inspect the o-rings and keep the stock ones ?

 

wow 60 bucks a piece will those work for our 7's. If so whats the differance between impedance or flow-matched? which ones should I get if they will work(mods in my sig.) what does (ECM driver modifications required) mean?

 

Rather than buy new ones, have them professionally cleaned by witchhunter.com

It's only $15 per injector and they flow test upon arrival, clean exterior (bead blast), remove/replace internal filter, clean, clean, clean, flow test again, replace o-rings and pintle caps, and give you a chart showing the spray patterns/flow before and after.

The turn around is usually 1-2 days once they get 'em.

not bad turn around, looks like it will take longer to take them out.

 

You can also have them cleaned locally. Almost any community over 50,000 or so has at least one injection shop. Check the Yellow Pages.

 

I'm also looking for injectors. Need a pair of 550's and a pair of 680's or 720's all low impedance. Haven't got an answer back from racetronix yet. But maybe someone here can answer this question. What's the difference between the peak and hold type and the saturated type injectors?

 

You can run either injector in your car with either the addition or subtraction of a series resistor. 680CC injectors were found in the GSL-SE RX-7 and commonly come up for sale on this forum.
