mazda rx2 rotary

Well guys after 4 engines in six months I have officially given up!!I hope the car will be running again in 6 months with a twin turbo small block chevy!!I hd thought about a 3 rotor but that would cost 10k by the time it was all said and done!the SBC will cost about 3k!my Haltech E8 will run the SBC but would not run a 3 rotor!the SBC will add 200 pounds but should make real good power and torque.just not enough rotor heads here on the west coast for technical support!I can't say I did not try!!

Welcome to my world..
Don't worry about the haters here and if you need any help with the SBC let me know..

WTTTTTTTTTT? I never thought you would take the easy way out Chris. Anyone can build a SBC, they are a dime a dozen. Don't be a sheep and follow everyone else. If you run a 8 or nine second pass with a SBC then it will be no big deal. Millions have done it already. You do the same with a rotary and it's an accomplishment. You already were running mid 9's all day long with your old setup. Why not put it back with that setup and just have fun with the car and get more knowledge on tunning and then when money is right, start to try new things. I would save up money and get a tunner that knows what he is doing and have them tune your motor and then get the knowledge from their tune and go from there.

For the love of Sam don't put a piston engine in that old school car or I will beat you down with an ugly stick! If you're going to go piston, then just go get an American chassis and sell the duece to someone who can keep it for it was meant for ---A ROTARY!

Why would anyone need any help building a SBC? Any moron can build one of those and go fast. Just go to your local race track and see all the sheep running them.

I always think about this when I hear whining about swaps.
It's funny, cause it's true.
Never gets old.

If I had a stock Fd block I would probably put a rock stock FD in it again!but to pick up a JDM engine I need about 1500! With that 1500 I am half way to the SBC!any body have a stock FD or cozmo engine they don't want?if it cheap enough I will put a rotary back in it one more time!kinda funny my one buddies that is a total American musle guy has told me to keep going with the rotary!

Hi Chris,
I think your too focus on the motor to much. I know you are running e85 with your haltech. You have run numerous mid 9 seconds passes, Wanting to raised the bar/ boost higher with your e85, I think you have to check if you are getting enough fuel in the motor. I think that is the problem rather than the tune that you have been mentioning.

If you don't mind me asking what kind of fuel pump are you running? And what is the pump rated if you run e85 fuel?

But tossing the rotary out of your rx2 would be such a shame, specially running in the mid 9 sec already. Think it over buddy.. Best of luck in 2011...

No hater here you need to go with what you can afford for the long haul!

Now me on the other hand i guess i just like getting kicked in the nut sack and coming back for repeat service!
Actually i built a 800 h/p motor and sized and tuned it for 500 h/p i call it insurance, so far its working but i still get the itch to push up the bar!

I sure hope whatever carnage you do is reversible. Hate to see you ruin a badass car but its your car and you have to enjoy it.... Thats what counts!


I always thought a v8 in a rx was equal to a chick with a dick...

I I'll tell anybody any thing they want to know about the car!! I am running 4 160 pound injectors,the aeromotive eliminator fuel pump that flows 900 pounds of fuel at 70 psi at 13,5 volts.I understand that the fuel flow at any psi if is above the fuel injector flow is enough for the fuel required.my injectors only demand 640 pounds at 100 duty cycle.so I believe I have enough fuel flow.now the injectors are enough for the boost I was running but it was nearing 90 present duty cycle.don't think my motors should have broke at this

enzo250

Okay Jay.. Everything is so easy... Everyone is running twin turbo V8's too..
You need to calm yourself a bit before you get beat with an ugly stick..

enzo250

Those aeromotive pumps really start to suffer at high fuel pressures..
The eliminator at 70psi is already down to 700-750 lbs at 13.5v.
I would imagine it could also be even less in your application hence the reason your at 90% duty.

At the end of the day you should do whatever you want to and can afford since it's your money and your car..

I know if that was a piston motor and you leaned on it a bit too much worst case you'd have a melted piston which could easy be swapped out.. No need for new motors..

rotorious13b

you need more injectors and a mechanical fuel pump..... and loose about 15 deg of timing . I recall you said you run 29deg?..... I sold my weldon 2035 fuel pump for $250( reg price $1000)
best thing I ever did. Yes we also had 2 weldon 2025 at one point same problem to get what the flow chart says, We need the right volts which means 16volts battery......Can you tell ,I hate electric fuel pumps what a waste of money . Chris back in the day everyone said to run alky you need 8 injectors ,but now everyone runs 10 to 12 .......all the new ecu's have more injector drivers up to 12 with 4bar , 5bar maps for all your rotaries needs . Chris I don't want to sound smart cuz I'm not
but if you get through this face of tuning you be ok

rotorious13b

What size turbo and how much boost Chris?

beefcake

its does sound close on the fuel setup, do you have data logging on the voltage as well, because my car was a solid 14.5 volts at idle but i found buy chance that it was down too 12.5 volts during the run ,belts were tight, so i had a week as **** alt and that's going to **** with the pump big time, at least i have injector voltage compensation tables set up
Plenty of people try to tell me i could go meth on electric , i look and , e85 is as good as classing it a alchy fuel

beefcake

Ps going piston is your choice , i was more of a stirrer in enzos thread havin fun , but deep down ill be happy if you get to the track in any drag car, any engine, just show us some skids haha

What did you brake in the motor this time ?

I had the eliminator too and it cost me two motors until we figured out the problem..

Chris, Pm brian(japan2la) , he sells used japanese motors with low mileage for
really cheap and they are in great conditions. He also sells blown motors for half
the price. He also sells irons, housings, you name it.

You drove the **** out of your car for how many years without problems with the old setup? How is a SBC going to get cheaper than that? Where you're at now it will cheaper to stick with the rotary and just go back to the old setup and then go from there. I have a complete 12a engine if you need any parts. I don't think that will help you but let me know. I also have two brand new 13b rotor bearings that I will give you if you need them. Let me know if you need any help bro, I'm here.

i'll admit i didn't read through all the replies but the last sentence got me.

the majority of rotary shops on the planet reside in california and in florida. of course the DIYers in puerto rico trump them all.
