A friend give me (free) four 370cc injectors from his 300ZX, I'm gonna buy a bored Maf, and reprogram my ECU with the s3/s4 program, intake and bored MAF. Do you think could be a good idea to put and program the 370 cc injectors in my car? I'm all motor, but I want to spray 125 shot with a direct port system that I order now.

My car It's not my daily driver.

THANKS

If you're using a direct port system the fuel will never see the injectors. Even with a dry kit, you arent changing the duty cycle, you are upping the fuel pressure so larger fuel injectors would have no benefit. The only way larger than stock injectors would be of any benefit is if you are flowing enough air to max out the stock injectors. That's pretty much impossible unless you strap a turbo on there. If you run a JWT 100hp nitrous setup they will be beneficial.

Sell them a and buy a better fuel pump.
