Just found out my primary injectors are leaking, so i have to get new ones. Now the 550cc cost the same as the 850cc and i already have the power fc to control it. Should i stick with the stock or upgrade? Im already upgrading my secondaries to 1300cc since i plan to upgrade to single turbo (i dont wont more that 400 rwhp). Any place that has a good price on those.........tony from rotary secret is kind of lagging and i need them asap.

 

ahh your fine with the stock 550....

 

Mazda Dealer price for stock 550cc injectors is $355.00 each.

RX7.com has a replacement 550cc injector for $195.00 each. Ask for Rocky.

I know because one of my primaries was leaking and I had to replace.
I asked the same questions concerning reliability and aftermarket upgrades. Since I', not going single and don't plan on racing with hybrid fuel mixtures, I was told that 550cc/850cc would be plenty.
