RC, A friend of mine is going to try to help me tune.

 

Don't buy them if you are thinking about them.

 

should I stick with the stocks?

 

no, buy the newer style injectors like ev14's don't have to big size, but you want newer style for better effieceny everywhere.

 

this one? http://www.ardesign.org/category.sc;...2?categoryId=8

It ranges from 440cc - 2200cc

 

here's the IC

 

I picked up my 650cc FIC (Fuel Injector Clinic) EV14s through Renown Performance here on MT. You can also look at ID (Injector Dynamics) through Trackspeed Engineering. These guys are all forum sponsors and can get you set up with the goodness. Or even get a set of Mazda OEM RX8 injectors via 949Racing. I think the RX8s are Denso style, but its still going to be better than RCs EV1s. There are also FiveOhMotorsports EV14s via eBay, but they have recently had some bad marks for consistency, so I cannot recommend them.

ANYTHING is going to be better than the super oldschool Bosch platform that RC uses. If you go with used injectors, send them off to DW (DeatschWerks) and get them cleaned. You can get a free service upgrade if you check out the thread in in the vendor section. After having my RX7 460s cleaned and seeing the flow numbers, I can tell you that used injectors can be scary...

 

I've contacted steph from begi, still no response. :[
