what kind of octane is good on my 87 RX-7 N/A? and does it make a difference if i use the 91 octane? : :banghead:

regular, anything higher is just wasting your money on a stock non-turbo rotary

What type of fuel should I use in a turbo 2?

I figured Id ask in this thread rather then waste a new thread and get flamed for this question.

Turbo engines uses premium only .

mazda won the lemans with 87 octane fuel, if im not mistaken, this was with an N/A car.
read the user manual and use the suggested octane, otherwise the timing could be fucked up

whats the fuel use on a n/a 7

mcs, read the thread.

N/A RX7s use 87 octane.

turbo RX7s use 91+ octane.

i meant how much fuel the car uses in miles.

17/25 non-turbo
16/24 turbo

Really depends... I've had anywhere from 12-22

thanks for that

yea I just posted what mazda said it got new

EPA ratings are BS anyway.

hahahahaha....ive been putting 91 in... :loser:

ad a 3 gallons of toluene to your tank of gas if you have a t2 it will raise your oct rating to 104. thoes octane boosters you buy in th e store will only raise your rating a few points like from 91 to 91.4
in the 80 the formula cars were running 80 % toluene. they had 1.5L turbocharged engines that produced 1500 hp. running 70 lbs of boost. think im full of shit do some research on exotic fules

what is toluene and where can i get some?

You can get it at any hardware store. Dollar for dollar, its cheaper just to go get race gas.
