Default 6 port 13b rotary turbo ems?

Using factory turbo parts, a guy on rx7club was able to boost his n/a 6 port. He did a rough street tune using the afc hack and it didn't blow up. Ignition timing was not controlled, just fuel. He drove it like that for a year (car was retuned on the afc, super lean at idle and increasing til redline. His rich map started at 3k when full boost hit on the stock turbo. Would i be able to make 10-13 psi on an hx55 using an afc without running out of fuel or having to back timing off. I want to run about 6 psi daily and 10-13psi when i'm feeling like smoking the tires off at the blip of the throttle.

Engine fire and apex seal death comments will be ignored. Mostly because it's bullshit and ignorance to believe such things happen to all turbo rotaries. A good tune and low-med boost will be fine on ceramic 2mm racing seals from what i've been reasearching and turbo 660 injectors will work fine. I believe the car already has 660's installed along with the turbo II maf. Car has bumper already cut for the intercooler. This will be swapped to the non running parts car and vice versa. I'm told the stock ecu can learn and compensate for alot of different variables which is good since i'm making another na-t car.

Before you start on me wanting a d series, then switching to b series then going rotary.......the car makes more power than torque, just like a honda but 100x cooler. Right wheel drive and no pistons. I considered fuel economy is going to suck so i'll still be on the lookout for an eg/ef hatch.

PS. I found 1 dohc zc (no cams) engine, and 2 b18a1 engines at the junkyard. There is a 1g parked next to my rx7 that i could probably snag the injectors and harness off of too. Let me know. I'm going back tomorrow and i'll just toss the zc head in the car along with the dsm injectors.

you failed joey.

megasquirt is a baseline option to start thinking about. air fuel hack on a rotary...Id say that guy had an feather for a foot or was really really lucky. A turboII rx7 can be found fairly cheap, buy one and play with that. 7's are not for the weak at hart, when it comes to tuning.

and I had a FB with a big streetport in it.

dud if you cannot work on a simple mitsubishi you should not get involved with a rotory. i guess it is fair to say that you still have not figured out that turbocharging a car is not common sence. maybe you should just buy a turbo kit and have someone that knows what they are doing install it

Theres nothing wrong with 2mm std apex seals. detenation kills apex seal tho and with no timing control you would be risking it.

Getting a dsm to run right is a chore. Rotaries are retard the ---- out of the timing, feed them a ton of fuel, let her rip.

Did they also tell you at rxFail club or whatever about the dowel pin sheering problem? Make about 350hp or so at the wheels and that 6-port will literally twist itself intwo. You think any of those big HP rotaries are FC engines? ---- no. Ive seen it happen and almost wrecked my car because it dumped 5 quarts of mobil 1's finest all over the blue ridge parkway.

There are quite a few ppl who have run the n/a 6-port from an afc hack. One of them is here in town. He drives the car like a grandmother in low boost all the time, and has rebuilt the ****** more times than im sure I know. Did you also know that you can max out the TII mass air sensor with just a boost controller? Know what the ecu does after that? It guesses. afc hack isnt really a good idea on any car when there are infinitely better options for similar money.

This is quoted for truth. Stand alone or bust.
