for me the problem is that I would like to upgrade the intercooler to a front mount,the pre cat to a downpipe and the cat with a high flow one plus I already have a intake and catback installed.Wih all these mods a good aftermarket fuel management system is a must.So converting to a stick seems like the only viable option.
Also I could be mistaken but I thought the rear gearing of 3.9 actually gave our cars less accelaration off the line compared to a 4.1 or 4.3 gear ratio.Someone correct me if I am mistaken.

 

maybe its time to change AT fluid?? and AT filters??

Mine shifts smoothly... except wen the engine is still cold. So i let it warm for a minute or 2 and then i go and dive it.

 

My auto shifts hard enough to kick your head back a little if you are not expecting it. When I am just slowly crusing around. I have a T78 and just about every other mod you can think of. Soon to be manual though, I have already ordered my new ACT prolight flywheel and Extreme Street clutch. Will be driving down to Dallas to pick up the rest the parts soon.

 

no, you're right, that's why switching to a 4.10 or 4.30 yields better acceleration.

 

check your FSM...stock stall is 3000. yeah 4.30 would be good for drag racing, not sure about daily driving.

 

Copy That, but, It doesn't change the fact that my 93 only gets a top-end stall of about 2100 before tire spin starts. And I'm averaging only 500 miles per month on the car so 4:30s wouldn't be so bad. As it is now, at a steady 80mph the car revs at 2800, so with 4:30s it shouldn't exceed 3500-3700?.

 

w/o power braking how is your car from a stop? I seems like my 88na when I had the 5/6 ports open. Like I can't whip a left u-turn in an auto FD but in an FC the car just loves to slide. On right turns though, It seems I can get enough boost to make it go sideways.

 

Hey if you put 4.30's in wouldnt it screw with the shifting when in D?? and also what do you mean by FSM?

 

areXseven... could a bad torque converter cause a lower stall speed?? or is that the opposite??

 

fsm=field service manual
not sure about your other Qs, but it does seem feasible. the ecu is computer controlled, so i think shifts are rpm controlled-so should be ok. speedo would be off a bit.

 

I'm sure that would only be one of the MANY problems associated with a bad Converter!!

 

wouldnt putting in the 4.30's kill top end power? like 120+

 

It will definitely kill top-end speed. Unless you like cruzin at 130 mph doing 6K rpm. But will produce much quicker launch/time and faster 1/4 mile E-T!!

 

Even though our cars cant use the power fc what about a piggy back to slighty increase the fuel? Like a safc or something? Also I was reading some people are running single turbo kits on an automatic how do you do it with a stock ecu? Last I have read in many diff threads you can use the powerfc you just get a blinking hold light or something to that nature. I could live with that. just my 2 cents

 

back from the dead! Well I run a single turbo auto and I use a PFC. I guess you could run a single turbo with the stock ecu IF you were VERY and I mean overly cautious that you ran no more than 10psi of boost. The SAFC does not add enough fuel to reliably run a single. PFS piggyback may work. Not sure about greddy emanage, despite initial claims the AEM ecu DOES NOT WORK with auto rx7s.

 

BTW this has been discussed ad nauseum. do a search on "PFC" and "auto", or "ecu" and "auto", or search under my user name (go back, way back).
