witch rx7 has the better fuel in jectors is it the 85 gxl se?
I'm trying to find better fuel in jectors for my rx7 could some please tell me witch one is with the better fuel injectors

 

There're not better, just bigger. They're 680cc/min I believe, but someone will confirm. The biggest Mazda injectors are actually 82-86 12A Turbo injectors, which are 800cc/min, but good luck finding those in the US!

 

i never new they had 82-86 turbo's

 

Only in Japan,the land of Skylines and REAL WRXs!!!

A "Turbo I" if you will

 

yes, '82-86 had 12AT in HB Cosmo, also '83-85 RX-7. That was the first turbo RX-7 which is why the FC turbo is called the Turbo II.

12AT had 800cc/min injectors.
GSL-SE (note spelling) had 680cc/min in '84, 720cc/min in '85 *this is not official but is based on net experience*.

They are only compatible up to a certain VIN on the T2's, after that they changed the injector impedance and you can't use them without too much effort (better off just getting the proper injectors).

 

there are aftermarket turbo kits that accomplish the same thing for the 12A engine. The intake is flat and square to accomodate the turbo.

the 12A guys are lucky - it's all mechanical so it's cheaper to turbocharge.

That's why 13B guys go carborated as well - or if your building a 650+HP dragster where you need ALLOT of air with little lag

 

my gsl-se injectors are 550cc... that's an 1984 model

Hope that helps.... maybe 85 is better, Gotta ask the first gen area.
