the top mods are fine however you would probably want to get your wastegate ported. also a bigger fuel pump. with the f-con and pump you should be good to 12psi, 250-275hp.

I'd be affaird of the streetport and turbo upgrade with out getting a way to manualy tune. atleast a S-AFC, haltech would be better. and you'll need bigger injectors. 300+hp

WHen i get my compressor upgrade i will definitely get the wastegate ported (89-91 turbo)..

I will buy a WALBRO pump for sure!..

Cannot afford a HALTECH now but i will buy S-AFC as alot of people recommends it!..HOW about a GCCII that goes with the FCON???..and i heard from HKS and from RETed that you cant run a bigger injectors with the FCON. HKS says that you must run stock 550 INJECTORS.
Any comments on this one????

What GAUGES do i need to monitor the engine and stuff like that???

WHO is giving good deals on S-AFC?????..

No offense man ( and I seriously mean that ) but it sounds like you need to learn a little more about these cars before you go doing all this.

Your upgrade path looks something like mine, except im just going to wait till i have the money for a full Haltech/T04 setup instead of wasting my money on a FCON(S-AFC)/Compressor Upgrade route.

From what i've read, i just dont think i'd be happy with that setup and have just decided to do it the 'right way'

that said, you setup looks pretty good, although i would definatly use a S-AFC over the FCON. Its a much better peice of equipment. Also, have you decided WHICH compressor upgrade you want to? There are a couple trims, and i would try to fit in the 60-1 wheel if i where you. You should also consider making your own intake, as it should save you at least $50.

For guages... How many/where do you want them?
I'd put EGT/Boost on the a-pillar, Water temp and Oil Pressure would be nice if you could jam them behind the stearing wheel in the stock cluster, but its easier to put them in the center console, and maybe add a fuel pressure gauge.

If you can avoid emissions testing (i assume you can since you are getting the full RB exhuast) i would recomend you also remove and block off the ACV, EGR, and anything else from the emissions system you dont need.

Have i made any mistakes?

Dude you're talking like you were born a ROTORHEAD!.. Ohhh i've learned alot about this cars trust me!!..Im not trying to be consited but i've taken apart motors and pulled a couple by myself with the help of HAYNES!..Im only asking HELP because im getting into a much higher level of working on this cars. Now why dont you sit yourself on the corner and shut the **** up!!!..I've read some of your post and they are very offensive to others!..

A lot of RX-7 FC's have problems with there idle. Not me thanks to S-AFC
Thanx for backing me up with that ADAM piece of PISt-On head.
Anyways, The thing is that i already have an FCON. Its one of the things i purchased while the car was sitting for over a year. The parts that i listed were all bought while waiting for a new motor. So none of them i have experience with besides my FCD and RB full turbo exaust... I will stick with the FCON though... I want to know though if i can use the S-AFC to help control the FCON.

You might want to see if you can get a "GCC" for that F-CON.&nbsp It basically does the same thing an A'PEXi S-AFC does...

Besides RETED you have given me one of the best advice yet!!!.thanx man!..you definitely did not make any mistakes.

For the compressor upgrade i've spoken to a couple of TURBO place and none of them made it clear to me.. I guess they were too busy or something (over the phone)
1) One guy told me that he can machine the stock compressor and put a bigger wheel???the biggest wheel he can put is an "H" trim???.

2) Another guy will put a bigger wheel and stuff it inside the stock compressor wheel??..

As for gauges
Im thinking of putting a boost gauge in a pod perhaps make it dual with a auto meter A/F gauge??..
I will install in the center console EGT,water temp, & oil pressure.
What do you think???

As for blocking off the emession stuff i already have that. I've already blocked off the split air pipe when i got my RB exaust.

An H-trim is about the biggest you can go with boring the stock compressor housing.&nbsp You can move up to a 60-1, but this required the 60-1 compressor housing, as the stock compressor housing cannot be bored for the bigger 60-1 wheel.

I knew there was a way to get a 60-1 wheel on there.

A/F basically tells you the same thing a EGT will, but much less acuratly. The A/F ussally just ends up being a pretty light show.

Aint i doing the right way???...i need to know because all i want is more than stock HP. Something strong and not CRAZY strong. Something above 250HP actually hoping for 300HP

For me, i've decided the compressor is not the right way, but for you it might be.


I just hate spending money when i just know im going to be throwing the part away 6 months later when i upgrade it.

My cars been sitting forever too.

Your not doing anything WRONG per say---
Its one of those things, that you can pay a little now, then more later, or just spend the more amount now, and only spend the money once.

I feel bad buying a FCD cuase i wont need it when i get the haltech... what can i say, i guess im ****.

I feel yah man!.. i was about to buy a T04B full turbo with HKS manifold but i heard from TED that i will need alot more to make it work in my car. Im in the verge of going CRAZY FAST with my RX7 but can not afford it yet. This car is maxing out my credit card and almost taking away my life savers. As long as the car is strong and stronger than stock and engine will not blow im happy with that!..I think HALTECH is the king of all ECU upgrade but since i came upon a used cheap HKS FCON i think this will give me a start.

I never talked like I was born a "rotorhead". I was simply saying you should learn some more about all this before you go trying to make the car. I dont know who "HAYNES" is but if you mean Hayes...well then you should know quite a bit more than you are showing. I said in the post that I didnt mean to offend you. If your pea-sized brain cant take a little criticism then you shouldnt be here. Ill go ahead and assume that english isnt your first langauge so I wont go into detail about the myriad of mispelled words and such. Youve probably only read my posts that I make in response to people like you. It really annoys me when people get on here and right away start asking "What do I need to do to get X amount of power?" or "Whats a rotor? I want a 9 second car!".

Why dont you sit yourself in that same corner you directed me towards, shut that ******* hole of yours, and read up on some of this. Its all been posted before so try finding the ******* search button and use it! Theres also sites all over the web that talk about it. Find them and use them.

CLAP CLAP CLAP to the smart guy!!...it seems like you have been reading the wrong manual!..I feel bad about people like you man!..you come here and start talking **** and are not sure what the hell you are talking about!..1 advice to you!..Do yourself a favor and go to PEPBOYS or something!..im sure they have a HAYNES manual for MAZDA RX-7 1986 thru 1991...SO you dont scratch your ***** because you just found out that you made a fool out of yourself attacking me with your smartassness
LOOK for that book!..its by MIKE STUBBLEFIELD and JOHN H.HAYNES.....IF i was there where you are i would drag your *** to pepboys or any of those auto parts place and shove the book up your freakin' ***!..

Now to end this argument one more advice to you. Pls stop harassing me here because all i want is to learn about this cars and not to learn how to argue with person like you. Im not afraid to report your bad manners to RX7FORUM.

I guess I could share with you some of my 87 TII experience. First of all, here is my set up, well, but remember, as anyone on this forum, I'm still in my learning stage, not an rotor expert.

87 TII
HKS downpipe (extended to pass cat.)
HKS Hiper exhaust
HKS F-con
HKS GCC
HKS turbo timer
HKS intake
SRx7 9.5 lb flywheel
ACT extreme pressure plate with full face clutch disc (more streetable)
Walboro fuel pump from K2RD
Racing beat strut tower bar
and some omni gauges on their way (custom back lighting)

I know this looked like a HKS sponsor car. But since I work at a performance shop, I could get good discount off from HKS, so why not getting them.

Well, so far, I have all positive experience over these mod and running without any problem at all, even in 120 deg. in texas. I set my GCC to sense boost instead of rpm (GCC allow you to set the thing to alter fuel according to rpm or boost). My setting are, anything under boost--no change (run with whatever the F-con setting), 0-8 psi--2% over the F-con setting, 8-12psi--4% over the F-con setting, 12-up (just in case the wastegate give up)--2-3% over.

I have this setting for almost 2 months now, no problem at all. I redline it everyday, day and night with AC on, no problem at all. Hope this will help. Good luck.

COOL!..how much can you get the GCCII and FCD????..PM me pls.
I think for now i will stick with my FCON.

I have this setting for almost 2 months now, no problem at all. I redline it everyday, day and night with AC on, no problem at all. Hope this will help. Good luck.

Youre such a ******* hoser you dont even know who Hayes is?...Im sorry man. I almost felt bad for you...But now I think youre just some foreign ******* that doesnt have a clue about these cars. Any monkey can take apart an engine with a book. You need to read some more about the physics of an engine. Maybe take some physics classes. Hell I dont know. At this point I suggest you grab yourself by the neck and toss your sorry *** off a bridge. And if you were here you wouldnt drag my *** anywhere you ******* homo. All youd try to do is rape it. Stay away from me. This "harassing" wasnt brought on by me my friend. I told you to try and read up on it some more but you had to reply with a whole bunch of self righteous bull **** so Im not gonna stop for a long time. ******* ******** like you really make me sick. Maybe you should learn to read and write the english language before you try to modify a car. You probably cant even tell the difference between your pecker and a dipstick.

OK, I don't want to get involved in this squabble but just wanted to point something out to Adamlewis. Some of the worlds fasted and best modified rotary engines are owned by people in Puerto Rico. Some of these rotary engine modifiers don't speak a bit of english so you're quite out of line to say that he should learn english before attempting to modify a rotary.
