RX-7 injectors

[Metapharstic]

OK for some this may be an old subject but i figured i would try to help those that have ben needing bigger injectors and thought about using the RX-7's TII injectors but didnt want to get the wrong type. I read about all the post on this subject and did alot of searching until i came across people that post and were using the right injectors off the RX-7's . Which are the 86-early 87 Turbo cars. They use the low impediance 550cc injectors. That Denso part number is 195510-1370 . I then went to my local Advance Auto parts and checked on a set for the 86-87 turbo RX-7's . Advance had a set of Beck/Rnley remanufactured injectors for 57.00 a piece. So i ordered four for a 240.00 plus tax. The part number for thoser are 155-0234 which cross references with the 195510-1370. The injectors fit perfect and the tab for the wiring harness connectors is correct . All i had to do was was adjust my SAFC. I have my lower honey comb removed and adjusting screw flushed so i richen up the idle with the AFC. I am still tuning and doing pocketlogger runs but mostly i have thigs set up around +30 1K to +15 at 4K on the Lo TH. The car so far is running great and guess what?? No more Fuel cut!! And only 2-3 counts of knock at 16 PSI with 19-20 timing..Hope this helps

Can anyone confirm this?

not the best deal IMO.

Racetronix.com. Look up Siemens Deka, they have the correct spray pattern for our intake. Any size you want 50-60.00 each. 550cc are also available in high impedance too.

Keep in mind, Siemens makes the injectors for accell as well. The post your quoted is for a set to fit a 4g63 fuel rail which the injectors are different that ours and they are low impedance so no they wont work easily.
