Like the tittle says, im a noob to this forum. A couple months ago i got rid of my 2g awd dsm and decided to go for something a little more fun and diff. So i picked up a 93 rx7 from michagan a few weeks later and here i am.

Im hoping to transfer some of my knowledge of dsm's and performance to working on my fd. Now i know its a totally diff motor and diff system thats why im learing and researching. And to end this post, i have a few questions that i would like for all you rotary kings to answer.

1. With the greddy pulley kit, do i need to get rid of the air pump?. Or can i just run the stock air pump pulley with al the other aftermarket pullies.

2. When purchasing the apexi power fc, do i need to purchase the commander with it in order to fine tune my self.

And thats it for now, hope to learn some more stuff and have fun with my car.

Welcome to the forum!

As an experienced FD owner, here's a suggestion, and I hope you follow it:

Leave the car alone for a while. I would spend about 3 months reading the archives here and current posts and researching before doing ANYTHING to the car. Seriously, there's always time for modding. Learn to drive the car as is and learn about the pros and cons of various modifications.

This ain't no DSM. This is a real racecar in street's clothing, and it will bite you hard if you don't respect it. It is also extremely finicky with modding and you really need to know what you are doing first.

Good luck.

My biggest recomendation is to listen to people like rynberg. The know what are they talking about. Like he said Leave the car alone and learn it fist before you put any money into it. You never know what you will find while you are learning it that may need replace. I'm talking from experience here. We don't call this car "Money Pit" for nothing.

Just take your time with the modding. Research everything your going to put on it before you actually do. It will save you time and money in the long run. You might want to think about the reliability mods before anything else.

I agree with rynberg, and the honda guy....Keep it stock for a little while. These 7's are like women; treat them good and they'll be good to you. They do not react well to half *** parts or modifications, and the repurcussions can be ugly and expensive. This is a relationship of mutual respect for sure!

I myself am probably considered a noob, based on the amount of posts that I have. HOWEVER......I have learned to use the "SEARCH" button very well, and 90% of my questions have been answered from utilizing this tool.

But, let me help you get started:

Thanks for the links, and i have already read alot of stuff from those links. And im still learning. As far as leaving it alone, it already has some bolt on's such as an hks intake and exhaust and bov. Im not really driving it much till i can get a fuel controller in there to richen things up. As far as doing reliability mods go, all vac lins have been replaced, i have an aluminuim ast, belts have been replaced and im currently replaced all filters and oil to be safe. I have checked over everything else and made sure all other fluids have been topped off. So right now its sitting in the garage looking pretty and shinny. And im doing the same thing as the dsm, letting it sit for a while, while i save money to mod it or fix things as things break, and when im not working, im reading tech articles and such to learn about this car.

So i hope to learn more shiat and have fun while doing it

why do you need more fuel? The stock ecu has been documented to run "rich"

there is a 3 mod rule that has been pretty much "debunked"...it's been changed to a 10psi rule...basically, you need a boost controller to maintain 10 psi

https://www.rx7club.com/forum/showth...ght=10psi+rule

rynberg

You don't need a fuel controller or aftermarket ecu with those mods -- see, you have more reading to do. The one thing severely wrong on Robinette's site is the 3-mod rule. You can learn much more about that topic by searching for posts regarding that, you can search using my username as I have commented on it several times..

Get a boost gauge and water temp gauge. Make sure you aren't boosting over 10-11 psi and aren't running too hot. It sounds like you're taking care of the routine maintenance. Other than that, go out and drive her and enjoy her!

black beauty

Boost gauge is already installed and im actually running 12. Which i read is about fuel cut time, and i dont hit it ( thank god , since its no fun ). Working on getting a water temp gauge ( installed as soon as its on my door step ). And the reason i was talking about adding more fuel is b/c i have a 3" turbo back exhaust with no cats.

And as you pointed out, i do have more reading to do

alberto_mg

Damn. how the hell are you only running 12psi wit a full exhaust? do you have a boost controller? that is usually the quickest way to a blown engine.

in order to run/add more fuel you need a PFC or some other ECU, but it you're not careful and run too much boost you'll need an engine.

get a compression test done soon before spending money so you know the state of the motor.

and listen to whatever rynberg says. i learned a lot reading his posts when i first got on here.

bee

Why spend money on a compression test? If it runs fine that leave it at that, you already own the car, compression test it when you think there is something wrong, otherwise your needlessly spending money.

Get a boost controller of some sort, search for "MBC" or "manual boost controller" you can make your own boost controller for really cheap and they work very well. Other than that, just keep the thing cool and at 10 psi of boost.

One warning, as many of us have found out, you don't need to hit the fuel cut to blow your motor. If your boosting above 10psi, you need a boost controller, stay out of boost until you buy or make a controll device.

One more thing, if you are unable to get your boost down to 10 psi, as occasionaly happens with full exhaust, come back here and search for "porting wastegate".

Have fun and be safe.

Oh ya, and most importantly, as you know this car is rear wheel drive.

DO NOT PUNCH IT IN THE MIDDLE OF A TURN, OF ANY SORT, THIS CAR IS EXTREMELY TAIL HAPPY. TRY IT IN A PARKING LOT OF YOU DON'T BELIEVE ME.

I assure you, you will end up facing the wrong way or worse.

not if you know how to counter steer ^^

Welcome and Congratulations! I have a few questions... How many miles did the car have when you bought it... How old was the person you bought it from? Any known history? Pics would be nice....

bee

Must be that drift king guy.

lol

I wasn't aware that we had a "fuel cut". I thought all we had was "Kaboom!" after 12psi without any fuel modifications. Am I trippin'? or has my mind failed me on the subtleties of a stock ecu.

I know that the 2nd gens have it and you need a fuel cut defenser to control for it.

kuning

I agree with you all, leave the car for a while.
I just got my FD for almost two months now. As the day goes by, I found more and more things to fix. And as I fix it, another problem arises.

As for now, I got this oil leak problem. I'm not sure about the main cause as it once had the same problem but now the leak seems to come from the oil pan.

One quick question, do you guys think scrapping the oil pan to the road might have caused it? Coz thanks to the poor FD's lightning, i went pass a speedhump w/o slowing down and a couple days afterwards I found some oil pond just under the oilpan.

Another noob.

rynberg

The stock ecu does enact fuel cut at 10.7 psi (above the transition, the fuel-cut psi level changes at lower rpm, do a search or look at the Ciriani site). The problem is you have to sustain that overboost for over a second (I don't know exact time duration) for it to kick-in. At which point you could have boosted to 17 psi and blown the motor....

In any case, 12 psi is not good, get a boost controller. You didn't mention you were running a midpipe initially. While the stock ecu is still rich enough at 10 psi with a midpipe, I still wouldn't risk it, personally. Too much danger of spiking/creep. I'm with Alberto though, I don't know how you are only hitting 12 psi with open exhaust and intake. Perhaps the previous owner messed with the pills, ported the wastegate, or installed a restrictor plate in the exhaust.
