Default Injectors

I have a question for those of you that have increased your injector size.

Here is what I have currently. I have a Devils Own WI kit coming so as soon as that comes in I can add more boost with the BBK.

1996 JRSC, smaller nose pulley, Powercard, MSD, JR Header, RB Cat Back

Currently, running 8psi on WOT

I read where Soflarick has pretty much the same components as I will have(I think) once I get the BBK installed. Except he has an EManage.

That leads me to my question. Can I run Toyota Supra light green top injectors(315 cc?) on a factory ECU, or do I need a Emanage to do so? I also have a 255lph pump ready to be installed too.

Just curious, and thanks for the help ya'll!!!

on a 1.6 yeah dunno bout a 1.8 the stock 1.6 fuel system got me 200whp with WI so put a fpr on there and keep the power card and turn it up this is your cheapest option.

So you are suggesting I run the powercard and get a FPR, and adjust the pressure via the FPR. Do that than get larger injectors like the light green top injectors from a Supra?

Also, With regards to a FMIC, what is a decent size IC to look for? Boost will be around 10psi, pre IC. I will also have water injection. I was just curious as to the total length, height, and core depth that would be suffient to do the job, but still allow the car to cool and the A/C to work properly. Thanks for the help.

18x12x3, or just get away with only using WI. 1.8 ecu should be able to handle 305s up from 265s, dunno how it would effect the idle AFR.

but unless your system is running lean, you're not going to be making more power just by adding injectors or an intercooler. It's going to require a bit something else.

Yeah, as a friend of mine suggest, go turbo, and make some real power!
Thanks for the response, I really appreciate it.

I'm not sure you'll need an intercooler. Look at the fast forward supercharger kit. 10+ psi 200+ rwhp & no intercooler. They are running a 5th injector to lower temp and add additonal fuel.

I'd try some 350s and go down if they don't idle. I'm thinking your more sophisticated obdII system will do it.
