Hey guys/ladies, I've been in the muscle car/truck world a while now, but recently purchased a 95 rx7. I've been doing one or two upgrades at a time, and am wondering what should be next. Here's a little rundown:
Rebuilt engine w/apex seals 10,000 miles
Pettit stainless down/mid pipe
stainless cat-back 3"
8.5lb unorthodox flywheel
act extreme clutch
pettit cold air intake
hks intercooler
mazdaspeed short shifter
That's where i'm at now... I'm thinking of a bunch of things, but wanted to know where you guys would go next.

 

ECU, pretty much anything you do next you are going to need somekind of management system like PFC or Haltech.

 

a programable ecu, or one like pettit's?

 

programable if you plan to keep upgrading, otherwise you can probably call up pettit or XS and tell them your mods, and have them custom reprogram your stock ecu to accomadate your mods... but an ECU is DEFINITELY wihtout a doubt your next mod. i'm sure you know, but unlike piston engines where you can mod and mod without changing the ECU, you shouldn't do more than 3 mods at a time to the engine without modding the ECU in some way or the other on an FD

 

surprised your car is even running right without an aftermarket ecu with the downpipe and midpipe...

 

no kidding.

growing95: You are in serious risk of blowing up your motor with those mods. I don't know how you are keeping boost anywhere near 10 psi. You had to have hit fuel-cut a couple of times by now....Seriously, do not boost above 10 psi with the stock ecu still in there.

 

I couldnt agree more, your gonna lean out with that midpipe. Engine will go bye bye

 

I threw a pop off valve in there until the new ecu goes in, so my boost stay's no higher than 10. Had to do that when the the mid-pipe went in because it was wanting to jump too high. So what ecu's should I be looking into?

 

If you are happy with the state of the car I'd recommend the reprogrammed ECU like Pettits. If you have any EMS experience and are gona go ape **** on the car then the PFC [fully programmable ECU] won't be a stretch for you...but do ask here before you dnyo tune, these are a little different when tuning.

 

are you going to be doing the tuning? if not, ask shops near you what EMS THEY are comfortable with tuning.
