is there anyone out there that knows some things i can do to a 1.1 rotery to make it faster without turbo or nos just like little bolt on things

rotaryxperamental

First: Full RB (Racing Beat) exhaust; header pre-silencer muffler theres been some debate on weather to use RB or Magnaflow mufflers.

Second: Weber or Delorto(sp)

Third: Second gen ignition.

Fourth: Gears ( he said bolt-on not tear down)

Am I missing anything?

what about coils is that going to make it any faster or what is it going to do for me if anything

1stgen racer

how much money is that knind of stuf basicly i am a 16 year old kidthat payed 4000 for my car a bunch of odd parts 3 extra motors and a full parts car so what do you think i should do to my car

You can perform the 2nd gen ignition mod for the cost of a 2nd gen leading coil pack (usually $20 bucks from a yard or Ebay). If you want to improve on that, then do the transistor mod when you install it, which will cost another 20 or 30 bucks. Made a huge difference in my performance... Contact gsl-se addict for the transistor package.

Other than that, remove anything that is not needed (emissions, a/c if it doesn't work, etc.). You can easily remove 60 - 80 Lbs of junk from the engine bay, which will help alot.

Also, you can pick up a used electric fan from the yard for about 20 bucks, then add another 20 bucks for the controller and you will feel a difference in 1st and 2nd gears.

Run some seafoam through the gas tank, then drive it like you stole it for about 20 miles. This will help free up stuck seals and restore compression.

Other than that, make sure that all of the usual tune-up items have been covered, plus a new fuel filter.

how much of a difference will it make on the horsepower or overall power of the car if i put heareds in replace of the exhost manifolds

mustang85GT

glad you ask'd. throw away those motors lol and put one of these in.
and just so you know(not trying to be an ***) its 1.2L hence the name 12a.

1stgen racer

i oucld have sworn it said that it was a 1.1 under the hood because they made the 1.2 as well as the 1.1 i thought maybe i am mistaken but thankyou and what kind of motor do you have there

True displacement is 1.146 L

12A is known as a 1.1L

1stgen racer

thank you i thought that i was right so do you know or anyone else know anything about headers and weather or not they will help me to the point that i should get them

mustang85GT

ah you know what, i think the 79's or 80's might have said 1.1.

that my friend is a 5.0 its about 3.8L bigger than the 1st gen average rotory. its a mustang motor. has about 235hp and around 300tq. and those are the stock numbers. these things handle mods very well and can made to have 450-500hp very easily, especially with turbos or superchargers. but there is one minor drawback, most rotary enthusiest, dont like these motors. everyone has their own opinions.

the other drawback is, you have to get bigger tires, unless you smokey burnouts at everystop sign. well if you ease off the gas, then you wont have a problem.

does that engine go right in the 85 rx7 or is there alot of other stuff that needs to be done and if it does how much were you looking to get for it

heres a couple more pics:

Loeave your engine in. We could start a whole flame war here but lets not. Someone (not naming names) just doesn't realize the potential of our little engines. Yes the RB header and exhaust system will make a difference. That and the carb are two of the best mods you can do to your engine. Plus, I'm guessing you don't have the money to do the swap to a v8.

mustang85GT

the motor just slides in. a couple things need to do though, if you have a 12a all you have to do is take out and spin 180 degrees the cross member,(the metal bar your engine sits on) after that you need to buy new motor mounts, they only cost 175 for the whole kit. and that includes the transmission mount. then the motor just slides on in. you might need to bang in the firewall a little though. see picture included. after that, all you have to do is plug in the wiring(which isnt hard if you have it all). also you need the driveshaft shortened. my car is not yet quite completed. but it will be by the end of this month. i cant wait to go to sevenstock(not to **** of rotary enthusiest. its just fun being unique[ask an Rx-7 enthusiest]).

i'm not sure what you mean by looking to get for it? i dont plan on selling my car. atleast not for a couple years.

there are a couple parts that require drilling holes, 6 holes total. so far, including the Rx-7 and the mustang and all the parts i bought for the car, i've spent $1500 give or take $70. i'm assuming i'll have her road worthy in about 300 dollars.

mustang85GT

thats just not true. i dont know any other car that can gain 50hp by doing a full exhaust mod(i'm talking about turbo 13b's.


also not true, if 1stgenracer has 4 motors including the one in his car, he could sell them peice by peice, do the swap and have money left over for modification. like i said, including the cars i only have about $1500 in my entire project. i'm prolly the cheapest guy in the world.

man do a simple turbo setup

I can hook you up with a simple turbo....... And intercooler, and wastegate, and BOV. All you need is better fuel pump and some custom tubing made, along with boost prepping your carb and buying a carb hat.

Kentetsu

LOL, so much for simple low cost bolt on mods....

FB II

hahahaha yea that's how it gets tho. might as well dive in now

rbf41182gt

you get about 25 hp from a racing beat exhaust system.

Actually, all 12A engines are listed as 1.1, not just the SA's. But as I mentioned previously, the TRUE displacement is 1.146

ApG Spaz

to start:
new fuel pump and reg (carter pump & holley reg = $85 or so)
exhaust (headers, straight pipe, muffler)
carb (holley, weber, sterling, do ur research to see whats best for u)

for future:
ring&pinion, TII tranny, or at least LSD if you dont have alrdy
light flywheel
rebuild one of those spare engines and street port it
turbo if that wasnt enough for you

(all 12a's are 1.1L, the name doesnt exactly come from that, i.e. 13G isnt 1.3L)

1985_RX-7

Im doing a turbo set-up and it set me back around $300 give or take.

Do you really just want to make your car Faster? As in a higher top end. Or do you want to make it run the 1/4 in a shorter time? What is your true goal. How much money do you have to spend?

Any pics of your car?
