okay i just put a rebuild engine in my 86 na with auto tranny and i have been driving it for over a week and i don;t seem to get any ***** in first gear. but in second gear it does what a rotoary engine does. so when stopping at a red light the car sits at 750 rpm and i press the gass all the way down and its like im driving a dam civic
any help would be great thanks

 

well your not going to get anything out of it with that auto transmission, they are terrible for n/a rx7's, your choice is some outragious racing auto transmission or do a manual swap (worth it)

 

remember to keep it below 5k and ***** foot it if its a fresh rebuild..

 

First gear on an AT is just that way. I'd spun out making u-turns on wet streets in my AT, just because it decided to switch to second at the worst time.

 

yeah i know that i have to keep it under 5000 rpm and its hard, you kno u have a civic with some loser in it and all you see is smoke from there pipe. but any ways i should ask how can i get more power out of my car and keeping it n/a. the engine is 10=15% ported, i like my engines nice and smooth.

 

You know JB, I almost did the same one night taking a turn just like you did. The only thing I can think of since another member on here has done this with his car, get your tranny overhauled and ask/request whoever is doing the overhauling, to add a shift kit to your car.

 

The AT died. It started clunking one day, then wouldn't shift out of first. Instead of getting the tranny fixed, I bought an '87 Sport that needed some work for $900. The AT is now my parts car, and I've got a peppy 5sp.
