Here's what I plan to run and can you tell me if its safe? I am not looking to hit MACH 1 speed, just looking to increase power. I keep getting mixed opionions - DOES ANYONE KNOW IF THESE mods are SAFE?
-------------------------------------
720 CC secondaries
Hi-Flow Fuel Pump 255
K&N CONE air intake
No cats, straight pipe (OMP disabled, premixing)
Performance Mufflers (dual)
Stock Turbo
HKS Ground Wires
FCD
Either a S-AFC or FCON.
Boost Gauge
AFC GAUGE
Blitz Turbo Boost Controller
-----------------------------------------
I've been told, "No, you need a GCC to operate the F-CON with 720CC secondaries" - Other say just get the F-CON or the S-AFC. Then I am told, No! you need to dyno-tune the S-AFC! UGh. What do I need here folks?

I read, read,read,read, post, read,post,read and I am getting more confused. Can someone just be honest here and tell me if this is safe or not?... please?

I dont know anything about the FCON but I do remember hearing that you cannot run bigger injectors without doing something else. The SAFC will need to be dyno tuned professionally unless you want to risk blowing your motor. It sounds like you have all the necessary mods for enough fuel (upgraded fuel pump, FCD and injectors).

But what good are these mods if I run the risk of blowing my motor? I WASTED money. I am not blaming the Rx7Club - but I just wish some people would not post when they dont know what they are talking about!!!!! F-N-A-HOLES!!!!

I did as I was told, read - search - read - search and now I am being told, "Oh those 720CC injectors now have to go on a dyno-tuner, sorry about that"

Should I just sell these mods and perhaps just restore the car? Get NEW 550CC's, new BAC, NEW TPS, new intake, less miles turbo etc????

yes, you should sell the safc and blitz boost controller. to me. j/k, but you should have researched this before going out and buying this stuff, then getting shitty with the forum members because of your ignorance. your going to have to dyno tune any programmable fuel computer or aftermarket programmable ecu. another option to dyno tuning is buying or renting a wideband o2 sensor and using that to tune the safc, but you sound like you dont have a clue, so i would still have a proffesional tune it.

I am not blaming anyone within the forum as I previously stated. I do blame myself, should have done more research and as a "newbie" to the rotary I think I put to much trust into the club. Only because they have been right so many times in the past *KUDOS BOYZ!*

I dont want to blow my motor and I know the car is plenty fast. I was just looking to push or weed out sum mo-horsepower.

Should I just get NEW 550CC injector, F-CON, hi-flow fuel pump installed, keep the straighpipe running no cats?

Mr. Gadget

With all due respect, the issues you raised have been addressed many times. When someone recommends search, it should be for more than one opinion. I myself have read many threads that contradict each other. I myself have been playing with rotaries since the mid 70's. I feel I am wicked with a carb but not so hot with the aftermarket electronics. I have been doing the same research that you have as I am building a turbo vert. Based on my searched, I think I am going with a street port, better exhaust, clean up the intake, cone filter and that’s it. (Injectors cleaned or replace as a maintenance item not an upgrade.)

I want this car to be a bit faster, BUT I want to drive it every day the sun shines!

Well, I went off-line and did some research and this is the reply I received:
------------------------
And stock injectors, with more pressure dialed in using the adj. fuel regulator, will handle that pressure just fine.

Adding a K&N filter, will let in a little bit more air,
but not so much that you would need bigger injectors, let alone giant 720s
If you put 720s on that engine, it won't run, it will drown !!

I guess you spend a lot of time on forums, listening to chat-room charlies, and forum fredies.
95% of the info from these sites is pure crap !!
Half those idiots have to ask how to put in new plugs..................
----------------------------------------
It does make sense to me. I am not upgrading the turbo, not increasing boost so why dump in 720cc injectors? I can create more boost with a FUEL PRESSURE REGULATOR, new 550CC injectors, AIR INTAKE, Boost Controller etc.

anyone beg to differ? Not being a jerk, I just dont know what is right here

Who gave you that reply? I dont see how upgrading injectors could "drown" the engine. If anything they are insurance to keep your motor running. With the free flowing exhaust, FCD, and boost controller upgraded injectors are recommended if not required. A high flow fuel pump is no good if your are pushing your stock injectors to max duty cycle.
