Rafael's car is still a mystery.. We don't even know what size injectors were in it when it was running pig rich. All I know is they are not the 7MGE injectors as they should be (since he's running the 7MGE ECU).
You could do it that way... but you'll have a restriction in front of the turbo, and it'll take a whole lot more tuning than just upgrading to the lexus. The FPR is not necessary, but really helps when tuning to avoid fuel cut, and getting a nice crisp idle.
Another concern is when you don't...
I use an action 6 puck sprung clutch kit from driftmotion. I've put maybe 1000 miles on it and I'm very happy with it. It takes a little time to get used to, at the same time I was getting used to no P/S but now that I'm totally used to it, I can't complain.
It really helps to have crisp...
Crisp,
If you have a brand new pump, you should be fine considering HKS tuned w/ it. If you do decide you want more power/larger injectors I'd suggest a walbro. Also, one thing to remember.. when you install the walbro it's a good idea to drill out the J-tube on the block for the fuel pressure...
Update:
I got the new fuel rail in today! I tapped it and got it on the car with no leaks! :)
I also got my car running as it was before the 870cc injectors/044 fuel pump. All I have to say right now is... WOW. My car sounds like a giant vibrator with an intank walbro in the back, and an...
That would be even better than the 2JZS2K I think... The tranny lines up like it should... and you don't hear people bitch about throwing off the balance of the S2K. Win-win.
You cannot just upgrade to 550cc injectors and magically not hit fuel cut. The ECU will still be reading the same ammount of air and you have not "told" the ECU that you're running 550cc injectors.. IF it ran, it would run terribly rich and still hit fuel cut at the same ammount of boost...
Crisp is right, it has everything to do with balance and misuse.
A brief explanation of what the HKS FCD is doing:
Let's say you're boosting 1300hz (according to the airflow of the AFM) and hitting FC.
The FCD is going to cap the AFM signal just before boost cut (1250hz or so?) and going...
