hey there everybody!, i am waiting for my 1.8 rtek ecu upgrade and i need 720cc*(min) injectors on both primaries and secondaries.. my rides a 88 t2 with straight pipe, rb dp, fmic and more stuff.. and currently pushing 12psi so my computer was going crazy and needed an upgrade.. anywho my question is what injector size should i use to maximize the 7's potential??? 750cc? stick to 720cc?? 800cc?? i found these injectors called "fuel injector clinic" brand that are pretty cheap and was wondering if anyone in here has any experience with them so they can give me a heads up on things.. here's the link: http://www.maperformance.com/fuel-in...-125-0750.html


thanks to all in advanced for helping me out!!

 

Anyone????????? Help please!!

 

The link I PMed you was the cheapest place I could find denso 720cc injectors in a set of four for less than 500 bucks. I do not know if the plugs are the same as the RX7, so I would write them an email asking them for a closeup shot of the plug if they have it.

 

thanks man

 

Densos, along with almost every other aftermarket injector, will be low impedance. An '88 uses high impedance injectors, so you will need to buy four 6-10 ohm, 10+ watt resistors to wire inline. Radioshack has some 10 ohm ones, but you can find a whole lot more through Mouser Electronics. I use these ones: http://www.mouser.com/Search/Product...GXqLtco3bU8%3d. Simply cut the four injector wires at the ECU, and wire a resistor into each.

The wires you want are as follows:

Pin 3C - LG/B
Pin 3E - LG
Pin 3F - LG/R
Pin 3H - LG/W
