All I can see is that they have INP-009 on one side with a "905" stamped in above it. Theres a B450L on the other and a "T" stamped above that.

They also have a somewhat light blue top.





Anyone help me out here?





Also, how much do you think I could sell the stock 550's for?

to my knowledge rx7's have the biggest stock injectors of N-D



get some ford power stroke 160# for like $80 each

yah i dunno what light blue is, nothing rx7 related



mike

You could have them flow tested to find out

that costs half as much as new bosch 1600's LOL

Just have one flow tested, thats $25 at RCeng.com... https://www.nopistons.com/forums/pub...DIR#>/wink.png

i guess but i don't think they will be bigger than 550cc if they are a stock injector

I think he meant he found some injectors, doesn't know the flow rating on them, and on a side note wants to know how much 550's go for. Used 550s go for anywhere from 30-60 a pop.

The injectors are from a friend. He got them to run on his t3/t4 miata but doesnt need ones quite that big yet. He bought them used froma guy and he said they were 720...I just wanted to make sure before I got them from him.





I need 720's and have 550's

He needs 550's and has 720's

It doesnt work out much better than that https://www.nopistons.com/forums/pub...DIR#>/wink.png

Sound like ND 720's to me. I don't know about the #'s, but I can check when I get home(I have one left).

i was assuming he pulled these off a wrecked car ah well

My #'s don't match, but that doesn't mean they are not 720's. Any light blue topped ND inj I have ever seen was a 720. They are very popular in Japan. My #'s are 195500-0830 cast into the plastic, on the opposite side to DENSO cast into the plastic. At the base of the plug is 727 cast into the plastic. Hope this helps.

Well thanks for checking https://www.nopistons.com/forums/pub...IR#>/smile.png Im pretty sure theyre 720's. I just wanted to be 100% sure.





Ill go ahead and trade my buddy for them https://www.nopistons.com/forums/pub...IR#>/smile.png
