i just recently got my 87' running. it sat at the previous owners house for a few years before i bought it. but when i finally took it out i was disapointed to find myself losing to my brother's saturn(no its nowhere near stock) but what i found was that i have no top end power. in the higher rpm's it feels like if i'm not even pushing the gas. why could this be? by the way it's n/a. is it possible to turbo or supercharge it?

check if 5th and 6th ports are actuating.

what RPM do you feel power loss?

I'm wondering the same thing about my RX7. I don't seem to have much top end power. But is the NA engine really supposed to have good pull past 5.5k? My engine pulls strong in first gear, but its very slow to rev in any other gear and it feels out of breath when floored. Trying to speed up 5-10 mph on the highway in 5th gear feels like I'm pulling a boat behind me. I do feel a slight kick at 4k when the auxiliary injectors are supposed to kick in so I know that's working. My car has 110k and is completely stock. Is this just the nature of the beast? I was under the impression rotary engines love to rev high but this car doesn't feel as spunky as my previous 92 Miata.

How common is the failure of the 5th and 6th ports?

i'm losing power at about 5.5 also. how do i check the ports? when i was racing my bro first gear felt really nice and powerful but after that i felt the same way as the convertible guy. and his saturn just came from behind and took me out. do you gus know of any rotary places near el paso, tx. (west texas). everyone here is hung up on hondas.

You guys still have the original exhaust systems on your cars? I'd check that first- that was the first thing to go on me way back when.... second, check the fuel filters, then the injectors
