Any hints on where to buy high impedence 720's at a good price? Is this possible?

 

No such thing that come from the factory...

RC Engineering offers custom bored out units that are not originally 720's, but these are not "cheap".

The ND's that GReddy offers are $136.36 full retail, but these are all low impedence fuel injectors.&nbsp Nothing a set of high watt resistors can't fix.

I see. Well with that in mind, I think I may go with 680s. Im currently just getting the T2 engine ready to install. Mods will include complete exhaust from turbo back, ported wastegate, ported manifold, removed twin scroll, removed 2nd TB plates, and possibly TID mod. Fuel mods so far are Walbro 255 and FCD. Which injectors will keep me safe? Thanks again.

 

If you're talking about 680's out of a 1984-1985 GSL-SE, you do realize that these are low impedence units, right?

Yea but it seems short of going to RC Engineering, most of the injectors I'll find are low impedence. So I may as well retrofit them.

 

Greddy 720cc injectors, $110 each @ rx7store.net

Are these high impedence? I hope so, they are what I plan on getting.

 

No, they are not.

Low impedance injectors are seriously no big deal - hell, if you can pull the upper intake off and put the new injectors in, you're more than qualified to install a 99 cent resistor from Radio Shack!

Guess how Mazda set up the '86-87 cars with low impedance resistors? That's right, they put a resistor block in-line with the injectors.

Easy to do, works great.

Why have a difference in resistance anyways? this doens't make sense to me at the current time.

 

So 680's or 720s for that setup??

I really don't know if they sell the ones you need......
