I got my SAFC-2 installed, and the car runs much better. With my RB20DET T3/T4 Turbo upgrade I had to almost max out the injectors. It's raining today so fine tuning will have to wait, but the car is holy $hit fast!

 

Dyno tuning anytime soon? Finally she is up running well, congrats

 

Congrats man, let's see some dynos.

 

Ryan, I got a set of 370CC RB25 injectors...I am not 100% sure if you can use them but I can get them to you for WAY cheap if you are interested....I know they are the same style as the SR20, but cant remember about the RB20. I might have an Rb25 fuel rail laying around also....

 

the injectors are top mount style like the DSM's, but aren't the same impedence as the DSM's. I have to get Turbo-2 RX-7 injectors or new aftermarket units.

 

The stock T2's are 550cc but is that both primary and secondary or just one of the two

 

maybe it's the N/A 13B injectors I don't remember which ones-saw it on some austrailian post.

 

the stock n/a 13b injectors are 460cc while the TII's are 550cc

 

thanks

 

I'm an rx-7 guy but would like to buy a 240. Rkcarguy do you have any ca18det motors right now? I just looked at your question again, and the 550cc are both the primary, and secondary injectors on the TII. A popular swap for modded N/A's is the TII injectors in the secondary's. Just a little more info, the s4 TII injectors are low impedence, and the s5 injectors are high impedence.

 

I have a clip coming but not much in stock left, only one SR and a Mitsubishi 4G63T. I think I need low impedence, not like the DSM's everyone puts in hondas.

 

hey, you guys seem to be pretty smart with the injector stuff. let me ask you this. i bought and s13 sr20 redtop the fuel rail thats on there has injectors with red plastic that say: 2c553303 on them i got a second fuel rail with grey plastic on the injectors and those ones say: 2e501152 and also have a46-00 on them. does anyone know the differenece if there is any and if wither ones are bigger?
Thanks,
Jay

 

RB20 an 25 use high impedance injectors.

 

I've read that the RB20 uses lo-impedence not like the RB25 which are a side feed high impedence, but I have conflicting info on this one HKS site says they are the high impedence another guy in NZ has been playing with a R32 and installed some RX7 injectors that were low imp. I have the low imp ones on the way already, if I have to I can add resistors to make them work.

 

I'm pretty sure the RB20's are high just like the RB25's. It's the GTR's that are low. If you look on skylinesaustraila you will see that when they use the GTR injectors they always use the converter box from the GTR too.
