HeyITZthatFC

this is the list of parts i just bought for my 91 N/A
1x Mazda Genuine Thermostat 89-95
1x Thermostat gasket (o-ring) 89-95 Rx7
2x NGK BUR7EQ Plugs
2x NGK BUR9EQ Plugs
1x Nippon Oil Filter - 4 pack
1x RP Aftermarket Fuel Filter - 86-91
1x NGK Plug Wire Set - 86-91

the car has had a tuneup with all fluids replaced, new crush washers, new radiator cap, new oil filter (FRAM FOR THE LOSS, thank god it's been changed..) and everything else a pretty good tune up consists of.. my question is, do i need anything else for the items that I bought? this is my first car and i'm planning on replacing as much as i can (hopefully everything) so it's pretty much back to it's original condition. sorry, I thought if I used the search function, the results would be a little too broad for my situation, thanks for the help.

i also want to know, other then what i have just ordered, what should i try to replace next? i was thinking the belts, o2 sensor, battery, and the grounds.

Check the faq, but it looks like you're doing alright for yourself. You may want to inspect the bushings and see if they're still intact. If you get too much play or if they're deteriorating, you may want to think about either getting new OEM ones or if you don't mind a stiff ride upgrade to urethane bushings. it all depends on what you want.

HeyITZthatFC

thanks, i'll definitely look into that, also, does anyone know where i can buy a FSM and any other books on 2nd gens or rotaries in general?

The whole brake system should be checked. Change rear end and tranny fluid if they weren't changed during the tuneup. Otherwise sounds like you're doing everything else.

The FSM is online and can be downloaded. Hit the stickies and you'll find just about all you need.

I have a couple 91NAs as well. In the process of a rebuild.

Gratz on the purchase.. and good job on the OEM T-stat. Lots of people skimp on these. There's no replacement for the OEM.

Sounds like you've done your research. Coolant hoses might be a good addition to your list. Most notably the ones from the firewall heater core to the block/radiator. Those always seem to bust and cause frustration. Might also want to get a professional radiator flush while you are at it...

Maybe a professional brake fluid flush/bleed... maybe the clutch too. (Note, if you do this, take a before picture of your brake/clutch areas.... The shops have a tendency to spill fluid everywhere.. Kills your engine bay paint).

soulja77

the rad hoses. get the car rust proofed. All the fluids.

HeyITZthatFC

thanks TurboII, the rear and tranny fluid has been changed, and I'll get to work on that brake system.... I believe I have a Coupe Package A with a sunroof (broken btw) so my rear rotors arent vented.. I think I'll try and replace those along with the brake pads.



Micaheli, thanks for the info do you know any reliable sites that sell them ? Should I look for any specific material, or do they only come in one type, also is OEM or aftermarket generally better?

micah

Actually, Package A had the vented rears and 4-piston fronts. So if yours aren't, you probably have a base 91.

Mine *WAS* a base 91... I've since put the brakes, tilt column, leather seats, etc from my 91 Package B parts car.


As for places to buy stuff:

http://www.mazdatrix.com
http://www.rx7.com
http://www.racingbeat.com
http://www.pineappleracing.com
http://www.atkinsrotary.com

Try and stay out of autozone for replacement parts.. it'll usually only give you a headache.



EDIT: For factory options reference, check http://www.rotorwiki.com/index.php/F...al_Information

Thanks

HeyITZthatFC

ahh, thanks. I remember reading in the faq that Package A didnt have vented rotors in the rear, oh well. Thanks for that and the sites.

-nobody mentioned the pulsation dampener. it could cause an engine fire if faulty
-cone filter with custom heat box
-o2 sensor
-battery cables/terminals
-the battery itself
-radiator cap (if needed)
-suspension bushings
-tie rods
-shifter bushings
-replace all misc. bolts (10mm mostly)

common problems...

-clutch cylinder failure (leaks)
-clean your grounds (especialy the UIM ECU ground)
-take the alternator and starter to autozone or something and have it checked (free)
-oil the sunroof tracks (cables prone to braking)

I worked at autozone and i can tell you that most of the **** there is not good for the Rex. the T-stats dont have the jiggle pin which is why the OEM ones rock cuz they come with it lol.

SOunds likeyour doing a great job. I should be following some of the stuff ure doing such as fluid replacement.

Have fun and welcome to rotaryizm

Fuel injectors should be cleaned if they are stock/original.

Then all vac lines should be replaced to be perfect but that can usually lead to issues when something is put back on wrong. So it's not a biggy.

Pulsation Dampner isn't a huge issues since he stated 91 which is not as bad as the S4.

HeyITZthatFC

can I buy new fuel injectors? what happens if you buy bigger fuel injectors then the stock cc? say like 720 or something lol .. and where can i buy vac lines? are there diffrent types other then for years? (as in 86-88/89-91)

no point in buying bigger injectors for NA's. the stock 460's are enough already.

stock injectors for NA's are cheap so you could buy 4 and then have them cleaned so there's no down time while replacing them.
you have an S5 car which has oval plug style injectors(high impedance). So you can't use S4 injectors(square plug and are both high and low impedance).

as for vac line. small amounts can be bought at checker/autoparts stores.

If you want a whole kit then hose techniques sells some awesome silicone hose.
rx7store.net sells rx7 kits and your buying from a community vendor.

HeyITZthatFC

rx7store sells fuel injector kits ? sweeeeet. as for the vac lines, you tihnk you could help me with that? no idea whats up with that stuff lol.. lemme try and do a search .. until them can someone please explain what i need!

As a general rule of thumb, whenever I purchase a used car (I got my NA in December) I just assume that the basic maintenance was either ignored or badly done.
For instance- I'm replacing the entire brake system (except the hard lines and I've already flushed them with new fluid) from the firewall to the wheels with either new or reman parts (I'm upgrading to 4-piston calipers up front), repacking the wheel bearings as long as everything is apart. Last weekend I dismounted the wheels and prepared for the brake upgrade by scrubbing the wheelwells clean (surprisingly easy to do and NO RUST anywhere-w00t!) and hitting all the relevant nuts/bolts with penetrating lube so I don't have any nasty surprises when I finally go to swap everything out.
It might seem a bit overkill but at least I won't have to worry about that system for a while.

Same with the charging system...new alternator and battery and will fab new battery cables (following Aaron Cake's writeup) at the same time.

My car is my daily driver and it's just easier to take on one major subsystem at a time and completely overhaul it. I've also been fortunate in that the engine appears to be in excellent condition and even through this last nasty winter, has started and run beautifully.

Now, if only the weather would quit being such a bitch and give me two good days in a row when I could work I'd be really happy.

-All other fluids are a good way to spend between 100-200$
-Spark plug wires (magnecor 8.5 are a great buy too)
-Brake kits (like everyone else said)

and beside that... with everything you already have.

I reccomend getting some speed bleeders and flushing the system with alcohol and then using some valvoline brake fluid, many of my friends have used it on their cars(we all autocross) and like it and doesnt have to be changed as often as the ate blue fluid. Although the ford fluid is a good choice as well.

If i had an RX-7 as a second car i'd definately go to the suspension and braking parts of the car first.

I was referring to Rx7store selling vac hose kits.

Injectors should be bought through the classified section. You can buy them already cleaned or old one and then send them out to get cleaned.
www.cruzinperformance.com cleaned injectors for pretty cheap.

The FSM and the forum have vacuum diagrams if you get lost. Or, don't touch them if you aren't sure of what your doing.

jonesfromindia

wheel barings anyone?

check those, easy test. jack up each tire, grab the rim and pull it towards you and push it kinda fast. if it moves time to replace... tires? lol j/k but ya i got duped on tires on my t2.

HeyITZthatFC

fuel filter
fuel strainer on the fuel pump or new fuel pump
air filter
new radiator hose
new radiator (strongly recommended -IHMO) as long is the plastic top oem radiator
check FAQ too tired to list all of them

Also check the FSM to switch the fuel filter removal. it is not that hard even tho is located under the car near the driver side, near the engine bay.
