UHH it's a rotary! Not so many moving parts and those things...that bend really easy when you run out of RPM's or that damn belt breaks! Go with the 13B-RE...BIG power, that's what I have in my car.

You can put any motor into an RX-7.

You can get hugely different levels of power out of a particular motor.

You'll need to ask the question differently to get a useful answer.

i really dont like to cross breed my cars, and i really dont like honda's thats why i asked cause their is a few honda's that roll around here and need to know what motor will dominate. Cause im getting a 87 rx with a 13b rotary in itand i was just needing to know would it dominate a b16 v-tech

I don't know where to begin.

"Top of the line" depends on what year of RX-7 you are referring to. For you '87, the top of the line option was the 13B-T. It is a 4 port 13B with a Hitachi HT-18 turbo that puts out 180 HP at around 5.5 PSI. With a few basic mods and some more boost you can get 250HP out of it fairly easily.

b16a= 160
na 13b= 146
turbo 13b= 180

realize that no matter how fast you are there is someone always faster than you.

Yea then he came back today and goes...it has a lil bit of a flat spot. I kinda laughed in my head to myself, and thought, well my rotary doesn't! lol So I told him he needed to adjust the timing.

A guy I know has a 240 w/ that rb26 motor in it, and my car w/ the 13B-RE would hang with it, and he has a bunch of mods and mine had none at the time. So those don't impress me either...there is only one engine that impresses me. The rotary.
