Noob Andrew from nor-cal.
 

What up I am Andrew I have had my 94 Miata for 8 months now still thinking of what I want to do to the motor. Was thinking turbo or sc but I have had my mind set on a 13b or if I can 20b so it is still up in the air till I get all my suspention set up. As of now I have fm swaybars kyb gr2 with sprint springs sportmaxx 002 15x8 with a 0 offset with 595rs-r rubber on them custom exhaust and a hardtop

v8>turbo>sc>...................................... .................................................. ....>shitty ass 13b
There's a reason every other rx7 out there is either v8 swapped or broken. Some things are great in theory but shitty in everything but. The rx7 engine is one of them.

Welcome.

Haha that's what everyone is telling me but I I don't want all the same turbo or sc as everyone else that's y I was thinking 13b and one of my buddies knows that motor inside and out so fixing shit won't be to hard

Its not the fixin being hard, its the fixin being a daily routine thing. My cousin had an rx7 and had to fix shit just about every day on that POS.

You want to be different? Build a BIG turbo setup. Like 40r setup with over 1000whp. Not too many of those around:giggle:

Ya but a even a 20b swap is less then that and I can get it to redline over 13000 And a Miata with 1000 hp way way over kill

:bowrofl:
How are those rocks you are smoking?

First off, a 20B will run you around 3k. Not that you could build a 1k whp miata for that much, but that's just for the engine/tranny/ecu. Its going to cost a shitload more to get it into the car and running. While I'll give you that a 1000hp miata is overkill, you could build yourself an extremely dependable, fun as shit car in the 250-300hp range for the kind of money you are talking about.

Secondly, 13000 rpm? Were you dropped on your head? 20Bs have a 2 piece eccentric shaft. Try revving that thing over 9k and you will have yourself a 3000 dollar paperweight when the e-shaft breaks in half, or when the motor spontaneously stops running from the apex seals being smashed against the rotor housings due to the vibration/flexing.

Edit: Sorry if I'm shitting on your parade. By all means, feel free to prove me wrong :). Welcome to the forums.
