Hello All,

I am looking to do some upgrades, and am looking for some advice.

Here is what I have:



89 RX7 Vert

Automatic Transmission

8mm Racing Beat Plug Wires

I believe that the rest of the car is stock, other than the rims and

possibly some springs.



Here is situation, and I need your input.



I have 1000.00 dollars to spend and am looking to Maximimize HP and

speed...What are the "upgrades" that I can do and what kind of HP

increases will I receive with each upgrade.



Please Let Me Know...

Thanks!

Aaron

5 speed conversion, intake and RacingBeat exhaust..

Thanks For the Reply....What about if I want to leave it automatic https://www.nopistons.com/forums/pub...IR#>/smile.png....So that my girlfriend can drive it....Then What

Then teach her how to drive stick.



If she can't figure out how to drive stick then you shouldnt be dating her.

5 speed conversion, exhaust, some type of porting, 5 speed conversion, turbo II motor swapp (1000 bucks is a good start into one) there are plenty of different ways you can go.

think about if you want to keep the convertable setup as well as staying n/a. it might take a while but if you wanted to go all out i'd say sell the vert and find a t2 and go from there. otherwise, other than the intake and exhaust which are perfect somewhat low cost mods (depending on which way you go) i would say standalone ecu maybe...?

For what you could sell that vert for you can get a TII.

That was the best idea yet!

Yes but the whole idea is that I wanted the vert https://www.nopistons.com/forums/pub...IR#>/smile.png

Thats why I bought the car....

$1000.00 does not go far in the world of rotary modifications.



Before you make power there are some things to consider. You do not disclose the location of the car, so you might have some better things to do rather than looking for power but acctually fixing some of the inherent problems of owning a FC.



Preventive maintenance and upgrades might be the better way to spend the money at the moment, here is a list of things I would do prior to trying to get any more hp out of the car.



Tune up:

new plugs, wires, and air filter, and oil change total cost: around $60-80



Throttle body mod (posted in the FAQ section at the top of the page)

cost: materials, around $10-15



Coolant flush and radiator, Rotaries are known heat monsters, getting the coolant under control is a must! I assume you are a new owner of the car, take a look through the porting and engine rebuild photos and look at the coolant passages of some of the torn down engines, over time rust and sediment build up in the engine, and will deteriorate the coolant's effectivenss. A good chemical flush and new radiator or cleaned stock unit will give you peace of mind and hopefully keep ypur 7 on the raod a lot longer. Total cost : around $75 for flush alone, around $500 with new radiator like a Koyo.



You did not state your mileage so you may be in need of a new catalytic convertor and O2 sensor, they do go bad over time total cost: $300-500 depending on what you replace. If you live in a non emissions area, $100-150 for a "test pipe"



fluid change for all other items, to include tranny and filter, rear differential total cost: $100 (est) I have not bought an automatic filter so I am guessing high



Cat back exhaust, this gets expensive wuick, if you don't need a name brand have a custom shop install it, if you need a name brand, your looking at half your money right there. Total cost: $250-800 depending on your preference.



This is just a small list, there is a lot more, but you need to get these things done first before the power

Then start with tranny and differential. 5 spd and some 410s will get you goin. Or if you wanna keep the auto then try the just the differential gears. Just check to make sure tour top speed isnt goin to be like 60 mph. j/k

How long ago did you buy the car? How well is it running? Is it in tune, out of tune? Fluids okay?



Do a thorough tune up of the car and get it running very well stock. Then consider modifying it.



Depends on where you live but....



Look in the FAQ section. Someone did a whole list of things that can be done to free up and generate power.

that's a fine looking convertable, real clean, keep it!



now, if you put a tii engine in it, get a light Al hood, FMIC, and change out the the whole transmission and drivetrain, and then did some mods. you will have the best looking, ultimate sleeping. you will be set. think of your RX-7 as a longterm college project, b/c that's what it is. and girls can learn how to drive a stick, i knew 3 that did and let them drive my car, and they did great, minus the lack of power steering. https://www.nopistons.com/forums/pub...DIR#>/wink.png



dont try to spend your money on a bunch of cheap mods, you will just waste it. do one thing at a time, and buy with the notion that whatever you do will permenantly stay on your car. then you will get your money's worth. and dont buy something that will change if you mod another componet, like exhaust for an NA if you get a TII engine.



5-speed conversion. you need this to slip the clutch at 4 K rpm to get a good launch and actually take advantage of any mods you may do. i had an 86 na, and it was the slowest car ever, especially off the line.

i agree

he has already said multiple times he likes the vert and wants to keep it. just because you own a coupe doesn't mean everyone else needs to. answere his question, dont change his question, just answere it.

I would leave the engine itself stock, if you want

something do a exaust, pay attention to local

emissions laws.



Dont go ripping out all the emissions and make the car

worthless. No one wants to buy a bastardized vert.



concentrate on cosmetic/suspension mods, the car you have makes

a nice cruiser, but its just not meant for speed being

its a automatic and its N/A. If you were to modify the car

it would become worthless. Stock verts sell and hold

thier value.

That's good advice!

Do the preventive maintenance. Put the car in top shape. And do the exhaust if you feel the need to spend more money. But don't start chopping it up!

BAH!!!!



Rip the emissions out, do the tb mod, get a 5 speed, and the 4.10 rear end. Then get intake and exhaust.



If your girlfried isn't good enough to learn to drive a stick then how's she gonna learn to drive a dick?

Here is another pic of my new vert..She is a little dinged up....but I will be fixing that soon https://www.nopistons.com/forums/pub...IR#>/smile.png

Here is another

Keep that baby in pristine condition. Everybody already mentioned the mods I would've, so as far as preventative maintanence goes, stick with that. 1,000 bucks won't get you very much, especially if you're looking to "maximize" your N-A's potential....try racking up about 3 more G's.....



Don't abuse her too much, that's for sure. Stick with what'll work, don't push her too hard....besides, verts were made for cruisin! ^_^

RX-7 specific wet nitrous kit on SummitRacing.com is $500. Afer completing all of your maintance to the vehicle, this will be your cheapest power adder.

I agree.

Yes but NOS is on demand power and can really ruin a motor...I am looking for consistant power https://www.nopistons.com/forums/pub...IR#>/smile.png



Aaron

Anybody ever try 4.10s on an auto trans? I wonder what it would do.

You should educate yourself more on the subject before you discount it. Nitrous mearly adds addtional oxygen into the combustion chamber. With proper tuning, nitrous will not ruin your motor. Just as with a turbo, you need to ensure the motor has the proper amount of fuel for it to work properly. Wet kits inject additional fuel along with the nitrous to ensure you are not starving the motor. Nitrous is the cheapest "bang" for your $$$ as far as power adders go. With only $1000 to spend, I would add Nitrous, upgrade my brake lines, fluid, brake pads, fuel pump, and add a header. In addition I would complete the TB mod/emissions removal and make sure all of the standard maintence items are up to date. The next step beyond that is to swap in a T2 motor, harness, and ECU.

you would need to find 4.30, verts come with 3.9 already



basically it boils down to how much you want to modify the car

versus keeping it original. If you do everything very carefully

( which most people dont ) and you can return it back to stock

should you want to sell the car then go for it.



Otherwise I can tell you that verts sells best stock.

You can buy a GXL or any lighter coupe RX7 and you can

go nuts with that one, or buy a TII.



and as much as you may hate to hear this- never mind the girlfriend,

if you start that **** now it will only get worse, unless she is the

one who payed for the car, do with the car as you please.

Find the rust and kill it, then do a tune up ande if you have any $ left buy some fuzzy dice.l

Fuzzy Dice? LOL
