First off, i say hello. I'm really a nissan Z guy. But i have a buddy with a 94 acura integra non-vtech. I love turbos, and he is inspired by my 300zx. We are planning on turboing his acura but can't find the stock fuel limits. I know the stock map sensor doesn't sense over 11lbs. But that is about it. I have an aftermarket fuel pump already so that isn't a problem. So i am now concerned about the fuel injectors. At what power level do they usually max out at?

 

Hello and welcome.

I wouldn't even consider adding a turbo setup without adding larger injectors. The stock 240cc injectors will probably max out at 180-200 whp depending on fuel pressure.

What are you doing about engine management?

 

Well like i said i'm new to hondas. The standard in a z31 is romulator with nistune, but i am about 100% sure that isn't an option. I am trying to put off new injectors because of having to setup management and tuning it. What if I set up an rising rate FMU, how far would that stretch out the stock injectors. Or do they have a tendency to leak at high fuel pressure? Remember it is a stock non-vtech, also we only want about 6-7psi to start with on a garret T3.

Also if that is still pushing it on the border on the injectors, what are some simple systems that won't break the bank too bad?

 

Nissan engine management is not an option for a Honda.

If you want to make unreliable, subpar power with a high probability of blowing up the engine, the FMU with stock injectors is perfect.

Look into Crome and Uberdata. They are both "free" to download the ROM editor but you will need to purchase either a chip burner or romulator, a chipping kit for your ECU, and datalogging hardware. In the end, it will be a lot cheaper than a new engine.

I'm going to move this to Engine Tech and Tuning.
