what is the top of the line motor for rx7, let me know

 

20b
13b-re
13b
12a
10a

 

so how much better is the 13b rotary to the b16 vtech in a honda how does it match up to it

 

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.

 

I think it also depends how deep you pockets are...lol And who will be doing the work.

 

Aaron Cake eats it again!

he couldn't have stated it any better ;p

Thanks Aaron, you are the greatest ..

 

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

realize that no matter how fast you are there is someone always faster than you.
h23 civic hatchbacks have been known to outrun vipers just on motor alone.

 

ight thanks for that insight

 

what i'll be running with i dont think any of them have h23

 

i think the really only comp i would have would be a prelude with h22 or a crx with a b16 v-tech

 

but if someone thinks other wise let me know somthing lol

 

Is your car a n/a or turbo?

 

no but im swoping it out with a jdm turbo rotary

 

Well that's all you'll need, I worked on a guys Honda Civic today that he did the motor swap on and I was no were near impressed with it at all.

 

lmao thats funny

 

what about the rb26

 

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.
