Where or where to begin. OK i have a 84 gsl. I want to do some upgrades but dont know what to do first. Most people i talk to say the exhaust system and headers. I found a pacestter exhaust system and headers for resonable prices. Are these good performance parts or are there some better? If so any web sites you know of? I have a stock carb. Should i first upgrade the carb? If so what are some good carb upgrades, website? If i put a straight pipe on the exhaust instead of a cat. converter is that still streetable or will it be too loud? One more question. Are these high performance air filters whith the money? 65 dollars for what...10hp or more?
Thanks for the help
(anyone who replied to my last thread thanks for the help guys...)

Well exhaust is reccomended first as any other mods will be complimented by that. How bout setting a goal for the car. Any racing in its future? Just a hot rod for the street? And what kind of budget are you working with?

Youngblood84

Well the goal is to get a street legal hot rod. I want to get low 14s or high 13s on the 1/4 mile. My budget is about 2000 what now but with every pay check it gets higher and higher. What exhaust would you reccomend and what about the cat. converter or straight pipe. Also I just found out today that my carb is in my shape. Any suggestions on a good carb for about 650 or so or should i spend more?

If you dont need emissions, go with the RB system. The streeport system gives more top end power with a little sacrifice down low. The SP systems is definately the way to go if you plan on going to a ported engine later on. Then after you got that done, do the emissions removal, go to an electric fan. Next would be the induction system. Lotsa choices there. Holley, Weber, Sterlingcarb.

Did you see my recent post regarding the yoohoo belt? If you decided to keep the clutch fan, the yoohoo belt is a cheap way to prevent belt slippage after removing the air pump. If you go with an electric fan, then all you need is one belt.

I think I'd go with the RB dual pipe (called their street port) system. I think I'd also go with a Sterling carb for the excellent tunability and drieveability it offers. I'd definitely set up DLIDFIS too.

Youngblood84

Ok when you guys talk about emissions i assume that means the e check correct? If so yes i have to have it past echeck unfortunatly. I didnt see the yoohoo belt post but ill check here in a few min. Can i still port my engine and pass the e check? I dont know if its a stupid question but what is a RB system and a SP system. I mean i dont have any clue what those are. What is DLDFIS Jeff? Sterling carbs what web site would be the best for that? Thanks guys for the help i greatly appreicate this.

I found some info on electric fans and this post made me concerned.
"i will keep mine with a stock fan, if you are driving your car more than once a week i wouldn't run an e-fan but that is just my preference unless you find a bulletproof setup, which i haven't seen one yet... on a rotary even one moderate overheat can blow your coolant seals, not worth the extra 2% HP gain to me."
I plan on driving mine more than twice a weak so would a electric fan be a mistake for me?

go to website mazdatrix, all your answers will be taken care of. Also welcome to the club. Rb, stands for racing beat exhaust, made by the company called racing beat which mazdatrix sells. It is one of the best systmes for exhaust that you will find. sp, stands for street port system, which gives a higher rpm band for power. If you have to go thru emmisions, street porting greatly affects this. Street porting is like changing a camshaft on a piston motor. Mazdatrix has all the info on this.
The exhaust system once you have done it is very simple to change back and forth and nets you aprrox 20-25hp. Filters like KN are good investments because they allow more air in, but they do not gain more than 2-3 hp at upper ends, still good mod. Fabricating a cold air intake system is also beneficial. If you wnat to free up horsepower, then you need to go to a lightened steel flywheel, no hp gain, but very noticeable throttle reponse under acceleration because you are reducing inertia which allows the hp to be used much more effectively. You will want to change your clutch anyways because of adding hp, the stock system will not last if
you are hard on it. to get a feel for a lightened steel flywheel will feel like, take your fan clutch off, get some shorther bolts to keep the pulley and belt on and take
it down the street for a test drive, for 5-6 blocks, dont worry, it will not overheat unless you sit at idle for a long period of time. You will notice it right away,
Anything that you do to reduce inertia frees up the available hp that is ther, does not increase it but feels like it does. For ignition lastability, get a set of either ngk wires, racing beats performance or accels 300+ thunderbolts which have been dyno on hondas and gained 1.8hp over the stock wires, dyno tested by accel wires
accel power cables which have not been released to the us yet netted
2.7hp over stock also dyno tested by ngk.Stick with ngk plugs and high quaility ignition parts like factory mazda or bosch. feel free to pm me with any questions , i ususally get back to you the same day. rx7doctor

DLIDFIS is a different type of ignition system that has been proven to greatly affect the performance of the rx-7. Jeff is a person on this site who can help you out with this. Sterling is a person on this website who rebuilds stock nikki carbs to add flow to them. He and rx-7 carl are in it together, so you can talk to either one. I hope that clears up a few things. And there are loads of people here that drive there cars everyday, and use an electric fan, so I don't think that that person knew what they were talking about. Good luck.

This was written by an idiot. Every single front wheel drive car available today has an electric fan. Most rear wheel drives have them. They have had them for years. Electric fans are light, reliable, nice to look at, whatever. They are just straight up better than clutch fans.

I agree with alot of you guys but for starters Mazdatrix have great parts for some people but they have a 3 rotor turbo and can bearly do 10's without some damage I think racing beat would be the best for your buck until you have personaly figured out witch part from mazdatrix will be best for you. Oh and the electric fans work great but is not worth the money unless you have the money,or just realy need an electric fan ask more questions if your not sure ask people who have done these things already.

DAVID GRIMES

Yeah. Exactly what he just said.

By the way, here was my thinking when I started my upgrades. I figured that the stock carb was actually in essence over carbureted for the engine since the stock exhaust was so plugged up, so it would be pointless to add a carb setup with stock exhaust because there would be no where for anything to go. Thus, I added a full exhaust system which will net you some noticable results even with everything else stock. Then, I played around modding the stock carb with mechanical secondaries and stuff (search for it), and it ws fairly fun. When I could afford it, I went with a Weber intake system to compliment the exhaust, so now the engine was breathing efficiently. After that, I decided with the new flow of air/fuel, I might as well work on the ignition to improve the combustion, so I installed the DLIDFIS system (once again, search). Granted, you can do anything anyway you want really, since all the mods kind of tie into eachother and youll get max performance once youve done them all (duh), I just liked my logic to it, lol.

~T.J.

PS - For the record, my first mod was an electric fan, and Ive ran my car with all kinds of mods and never had a problem with overheating. Even when the relay for the control box died (twice, be careful when you wash the engine bay, lol), it never even cam close to over heating. Just keep the car moving and you should be fine, assuming your radiator is in good shape and allows the water to circulate like it should.

EDIT: Just remembered you were talking about needing to pass emissions. What I would suggest doing then, it going with RB exhaust, but have a custom pipe made to bolt in with a cat converter when you need to pass emissions so you can just swap a section of pipe. Or even just keep it installed indefinatly, its up to you. Then get yourself a fairly "stock" carb that performs in non stock ways like a Sterling carb or something. Im not too familiar with what needs to be done with one of those, like emissions equipment and what not, but personally, thats how I would approach the situation. If you check out my website in my sig, you can see how I did things in my old 83.

Youngblood84

Dang...I just could a crap load of great advise. Thanks so much guys. Just found out today my mechanic said that my throwout bearing had been shot throw my pressure plate when he was in 3rd gear. Just wondering anyone have that happen with a crappy stock clutch. The guy i got it from bought it from autozone so i know it was crap but it worked for a bit. Let me know if this ever happened to you im just curious...iam i being fooled or is he serious?

DAVID GRIMES

The stock clutch ain't too bad at all. It's when you start trying to make it handle more than it was ever designed for that it seems insufficient. Same goes for most of the whole drive train. It's all got to balance out or the weakest link will be the break or the failure. FWIW

Youngblood84

Yea but David everything else in the car is stock so i wouldnt consider the weak link. But have you heard of a throw bearing shooting through the pressure plate or clutch plate whatever...i was just curious bc all of these probables i dont know if im going to cont. with this rx7. I mean its just bunch of new parts and only 120,000 orginal miles 84 gsl. Its got a tranny with 80,000, new clutch master cyclinder, clutch slave master cyclinder, new fuel pump, sway bars, brake master cyclinder, tires, cv boots, water pump, oil pan and gasket, brand new spark plugs, batt., brakes, distrubitor cap and wires, Starter, alt., belts...so question is should i replace the clutch then sell...or replace it and fix it up, or sell as is....carb is in rough shape but i have a stock carb that was rebuilt....inputs P-L-E-A-S-E...i love this car but is it all worth it?

DAVID GRIMES

If you truly love it, it will come back to you... just kidding.

Hell, look at the two bright sides:

1) There's only so many parts you can buy and you are pretty far down the list.
2) Even though it's a money pit and you have to pretend like it's not really costing all that much... It's still cheaper and more fun than playing golf or some other mindless twit thing.

Youngblood84

how much you think i could get for it with all these new parts?

Rx-7Doctor

iTrader: (13)

Well, why would you want to sell? As far as the throwout bearing, if the input shaft did not have alittle grease applied to the splines or the person did not replace the throw out bearing, which alot of people do not or the pilot bearing for that matter which is some what difficult to get out without the proper pulley than this can happen. As far as autozones parts, i would not use a clutch systme from them. the stock factory clutch disc is far superior, the only other aftermarket
company that supplies oem quality clutch kits that i know of is beck arnley, you can
get this thru napa or other certain parts stores. Remember guys, a electric fan install is not a horse power gainer but creates less inertia for the motor as frees up the available hp there. Stock fan clutches are very efficent for cooling, if you want to see the benefit, than do the removal of the clutch fan as stated in my previous thread response to you and determine for your self if it is worth it. It should take you approx 30 minutes or less to do this, probably about 10-15 in
reality. When deciding whether to sell or keep, you have to look at what you have
and what has been replaced, so you have a history of the maintenance. This gives
you an idea of other parts that can fail, remember you are dealing with a 20 year
old vehicle. you can always something new and have higher insurance and payments with interest and depreciation value after you drive it off the show room.
Or you can have a whole lot of fun learing to modify the rx7 and have a unique
vehicle that is a cut above the rest. rx7doctor

Youngblood84

well the thing is im not that good with the mechanics behind the rotary engine. I mean i can learn and all but these cars are old and often become a pest to maintain. My mechanic offered me a really good trade with him. He has a 95 supra with 75000 org. miles and turbo with a nos setup and other mods egually 400 hp. I mean he wants my84 gsl and 4000...i just cant get 400 hp out of my mind. What are the possiblilty of me getting my 84 rx7 as quick as this supra for 4000????

DAVID GRIMES

I'd say you can do it ( spank the Supra's *** ) with a whole lot less than 400 hp. If you supply your labor and get parts from forum members whenever you can ( for your turbo or carb and intake or whatever. )

But if your RX is a pig inside and needs paint and you have a bone stock engine... then if you want pristine **** perfect like I do, then prepare to let loose the wallet eating dogs of restoration and mods.

This can be a major investment over a long period of time unless you're Bruce Wayne or some ****. If you don't want to or can't make that commitment, then I would go for the Supra and hand off the RX to somebody that is.

Pelezo

Now,

You might wonder why he wants the RX7 so bad....

Youngblood84

never that about that...i guess he wants to upgrade it himself. i dunno money problems right now...if i dont make the trade how much you guys think i could get for this stock rx7 with all these new parts...interior and exterior excellent condintion....no rust what so ever....every time i check the blue book value it say 1200....give or take 200 dollars when i lower the milage to 5000 or jump it to 300000. that thing sucks on older cars with new parts and condition of body...but give me some numbers....84 gsl with 120,000 orginal miles 84 gsl. Its got a tranny with 80,000, new clutch master cyclinder, clutch slave master cyclinder, new fuel pump, sway bars, brake master cyclinder, tires, cv boots, water pump, oil pan and gasket, brand new spark plugs, batt., brakes, distrubitor cap and wires, Starter, alt., belts...so question is should i replace the clutch then sell...or replace it and fix it up, or sell as is....carb is in rough shape but i have a stock carb that was rebuilt....give me some numbers please...

Well first of all forgot about what kelly blue says. It is whatever the market will pay in your area. You have to look at other vehicles in your area and what they are
asking, the condition versus yours. No one wants to pay top dollar for a vehicle that needs a clutch because of the work. If they pay someone to do it, the cost is usually around $400-$500 parts and labor. If you get a beckarnely clutch kit which is new parts for around $150-$170 and install it your self, which is not that difficult to do, i wrote a thread on this. I had one down to like 40 minutes to completley disassemble everything including removing the flywheel and installing a new pilot bearing. What is your definition of excellent paint, no scratches, not faded, no dings or dents? Do you pics you can post of the car. I have bought and sold at least 25 of these vehciles over the years and always got top dollar because they were in really great shape. let me know alittle more about the this and i will give you some numbers to start at. rx7doctor

Youngblood84

Ok ill be changing the clutch again by myself its just i hated doing it all over again....i mean i just want to drive my baby and get her up and going. the more i keep thinking about it i do want to get this 7 to kick a supra with 400hp ***. but just cuirous lets hear some numbers....the paint is not faded, no dents or dings, no rust, no scratches...no pics...sorry wish i could show her to you all but now scanner or digital camera. Could you do one of this here was the thread on when you changed a clutch in 40min. I mean it took me two days....did you remove the tranny or enginge????
