Question before installing 86-91 rx-7 injectors

[xKnownShadowX]

I was wondering do I need a tune if I toss on some 86-91 RX7 (195500-1350) injectors on a sohc NA?

Thanks in advance.

Thanks in advance.

there is a formula for choosing injectors....ie..flow rate per cylinder to make X horsepower...its somewhere in this forum...this will guide you in choosing injectors for the tune or build you may be planning..good luck

the search function is in the upper rite corner under the google banner.

well..word of advice...if you dont have a plan for a build or a ecu tune..or an upgrade...dont waste your money...

I have a turbo kit that is sitting but my engine I think is not worth building into a turbo.I got two pairs of injectors, RC racing ones for the turbo setup and rx7 spares.I'm not wasting money I just got them sitting and I think my injectors need replacing, if not I just think I might as well replace anyways.

Let me know thanks.

My main plan was turbo cause I got most things I need but since I just went NA now might as well do something with the injectors.

nothing probably blow op your engine. rich on idle and lean on boost if you decided to turbo it without tune. figure out the cc on the rx7 (thinking 440) and see if its low or high impedence. then get someone to chip the ecu for your turbo set up
