yo zilvia just wondering how good or bad are rx7 injectores?

i want to upgrade my s14 sr20 maf to a z32 maf and run q45 throttle with a stock t28 and replace my stock 370's with 540's , what do you guys think(to much fuel)?

bl3ujay07 · 10-01-2009, 06:54 PM

you cant just swap injectors like that. you need some tune or management to run the maf and injectors. Plus, arent rx-7 top feed or is it just some?

S14_Kouki · 10-01-2009, 06:55 PM

You should not run a q45 unless your going for over 500hp. Z32 is a good idea you just need a fuel control and just upgrade to s15 injectors there good for around 400 plus idk if rx7 injectors will work.

S15 injectors are good to about 300whp, not 400

how much power are you wanting to make? you don't wanna start spending money on parts you may not need.

upsdude · 10-01-2009, 11:31 PM

You need spacers to fit RX7 primary's into the fuel rail. Plug/harness adapters too.

Its really not worth the time, you would be better off buying new injectors that are designed to fit into your fuel rail... If you do go the RX7 route you should definitely flow test them, replace the o-rings etc. And I have not seen anybody who makes a plug and play harness for that setup.
