what can you do to make 1982 rx7 faster
 

I was wondering what kind of modifacations you can do to a 1982 rx-7, to make it faster. I have the standard engine in it. Price wise would it be cheaper putting in a chevy 350 small block and will it hook up right.

Then why not just put that 350 in aChevette stay GM.

All advocates of the "V8 in an RX-7" concept need to be shot in the nuts. If you want to make it faster, go with a 13B single turbo setup, not a perfect weight balancing destroying V8.

there are tons of easy mods. Racing Beat exhaust system frees up huge amounts of HP, a less restrictive intake (custom CAI or K&N drop-in) will get air into the carb quicker and with less restriction, swapping out the stock carb for a high performance one, etc. etc....


These can be done in stages, not an all-or-nothing commitment to your time and wallet like an engine/tranny/rear end V-8 swap

YYYESSSSS!!!!!
13B, either 1 or 2 turbo's, I don't care... Just don't put a piss-ton engine in there...
BTW: my car is a 1982, and it ain't that slow...

SO,,,you wanna go fast in your 7 ..??? Well how much money you invest is how fast you will go.. get-it ?? If you've got tons of bucks and are smart you could go with a 13b turbo. the people here who have done that are a different breed of people. PURIST's there's a lot of shit to do and buy to make a 1st gen haul balls.
It would be safe to say about $ 3.000 grand would take care of it.I'M gonna get-it for this,,,An american V8 would fit perfect, ford/chevy and under the hood too.
A 5.0 ford,,,cool A 5.7 (350) 4 bolt with 194's or 202's.
Me,, I'd go 327 solid lift ,, very cool,, but i'm a ford head,, so either a 5.0,, or, 289/271 hi-po or a 351 C 4V . I would wet myself to see a 1st gen with a 427 side oiler, hi-riser
with of coarse everything cobra LaMans. It could be bought for $ 5.000 grand in the crate from ford power parts here in california.of coarse the 2 660 center squirters would be sticking out of the hood by about a foot. you'd need a 9 inch ford rear, hacked, tubed frame,
tubed wheel wells, a lenco 5 speed, wheelie bars, steel nuts,no children, no wife, nuts of steel,, (did i say that again) get the picture,,,I can see it.. Oh i almost forgot to mention,,you'll need an ejection seat too... Lol

Talk pistons at www.v8rx7.com, not here. Although, I would be saddened to see another beautiful FB turned into this...Oh well, to each his own :).

PS - Im still willing to help you too. As Manntis said, there are plenty of good things out there, it just depends on what your goal is. You need to let us know about that first, then we can help more :).

Probably the best "bang for the buck" mod would be the Racing Beat catalytic convertor replacement pipe. I put one on my '82 S and was shocked and how much of a difference it made. The pipe is $90 and the gaskets are $12 (replace 'em, DO IT!) but the thing weighs ten pounds and could survive a nuke attack. While most here seem to hate it, if you want balls out power with minimal tuning or reliability issues, the V8 is the way to go..

Read my sig, but that blows the theory of being cheap :(

This is the best bang for the buck:D

BANG is right, ask Setzep about it LOL

Your question can be answered with one simple word: MONEY!!! Next question, please?

I'm fighting the urge to say something like "go get lost, piston boy", but I won't.

Sure, a V-8 will give you loads of torque and be fast in a straight line, but what happens when you lift in a corner?
What happens to the weight distribution when you put in a V-8?
How about the gas mileage?
Okay, so that's not the best example.

The rotary engine has more going on than just horsepower, if people can't see that, then they SHOULD bastardize their RX7 with a V-8.



...as long as it's a Boss 302.

booooo Ford.....
Booooo Piss-tons.....

ahve PIneapple racing build you a 12a streetport, with lightened rotors, 2mm apex seals, hardened stationary gears.... less than $3000 for a motor that makes 220 Hp and has a 3yr,36,000 mile warrenty......
Damm, fuck the pistons!

come on now. v8 is a good option if youve got one laying around. i wouldnt touch the heavy chevy, but a 302 swap is great. the weight distribution is really close once you move the battery to back and get aluminum heads and what not. parts are easy and cheap to come by and tuners are wayyyy easier to come by for holleys or even stang efi setups. mike hows your tuning coming?
keep flamin the v8, but if it werent for hotrodders back in the day with their pistons, we wouldnt be here. so have a little respect for your ancestors :-P
dont talk about the weight of a v8 being way off til youve ridden in one. kerrys car feels damn nice with a 302 in it.
no need to go over the v8 discussion agaaainnnnn
but yeah, you wanna go fast, get $$$, thats what it boils down to.
gamble

If you really want the answer to speed and keep the handling ,I have been kicking around the Idea of a
chevy 3.1 v 6 out of a lumina, its light , and will give lots of power to weight ratio ... but I will not give up
on the 12a, besides whats the speed limit ? .....

Yeah you looking to go street/strip, track only, drag race, rally race, drifting, or you going to be delivering pizzas?
Tell us somethin' brotha;)

does anyone else hear a v8 debate coming on? i know i do so im goign to keep my mouth shut and ignore this thread...

the v8 debate is pointless, most poeple here like me think its dumb and ruins the weight balance of the car, and others think its cool. Nothing anyone on here can say will change anyones mind. I don't why they even bother to try.

I agree about the V8 debate. the only reason why I said anthing is because I havent said anyhting before... figured I would bitch al least once.

If you are going to go 6 cylinder go 4.3 Chevy or 3.8 Buick Turbo. Sometimes I wish I had kept my car rotary but ah well. Just a question... wouldn't an intercooler/bigger 13B/ turbo's etc. throw off the balance as well? I suggest unless you have fabrication skills and determination stick with the rotary and get a nifty RB exhaust.

there's always the Mr. Fusion hovercar conversion kit...

:hah: :hahaha: :rofl: :hah: :hahaha: :rofl: :rofl:

I have $50 for anyone that will complete this project!!!!!

Does that come with a flux capacitor?

I got an extra one I can donate to the cause:D
https://www.rx7club.com/forum/attach...&postid=808160

Yeah, give me one of those!!!! :D
Want to travel in time and give Felix Wankel all his research material... I'll go back to 1923, and show him all he still has to learn about apex seals etc. Then he can built an engine in 1924 instead of the fifty's. And you know what? We wouldn't have those damn V8 conversion-debates no more...

The reason i've said a word about V8's is this,,,Every person here, who turbo'd there 1st gen has, (1) spent over budget.(2)had to buy some really expensive parts.
(electronics)(3)It seems that they are disapointed, the car is not as fast as hoped for ( granted, the car IS faster)(4)maintance, you've got to be totally in to it, and have the bucks allready if something fails, one just can't throw a turbo on and think thats it !! Now don't get me wrong. I dig MY 12a stock 82, I know for stock my 7 goes really good, it's surprizing...and an -SE would be faster/better. To me. to pull up next to a 1st gen at a light and hear the sound of a hi-performance V8 (like a boss 302) would just make me smile and say 'fuck yeah' !! Not to many cars still have the balance of a rotory engine RX7 for the twisty's though IMO

V-8 or V-6=vibration
RE="Hmmmmmmmm"

If for some insane reason I was going to put a V-8 in an RX7, I would consider the old aluminum block Buick as a likely candidate. -WG

A good V8 hardly vibrates at all - next to an inline 6 it's among the most balanced piston engine produced in significant numbers (I don't include V12s or W16s for that reason)

However, it's still pushrod technoligy in a tiny, nimble car.

Those who knock V8s have to remember a certain American who made a name for himself by stuffing V8s into a small, nimble British sportscar called the A/C Cobra - so much so that decades later he'd convinced himself he'd created the whole car.

Thos who knock rotaries and favour V/8 swaps have to remember the whole unibody was engineered around a firewall hugging, breadbox sized engine that uses a completely different technoligy than other combustion engines in cars, thanks to a dedicated team of tireless engineers valiantly pursuing rotary perfection while V8 manufacturers like GM failed at similar attempts

I am not going to say anything......:uzi: :bgfuk: :hf: :hf:

A good V-8 hardly vibrates at all?
Compared to what? An inline 4?
Certainly a straight-six is one of the smoothest piston engines, but still not as smooth as a rotary.


Regarding GM, the Monza was originally designed to use a rotary engine, but GM decided against it because they felt that if an American company put a rotary in a car, it would lend legitimacy to the rotary design which was viewed with much skepticism at the time. Indeed, the longevity problems with the carbon-seal motors almost killed Mazda in the mid '70s. -WG

Yes, compared to other piston engines.

And note I said a GOOD V8.

Lexus makes a few examples of those.

Ummm dont you mean Toyota? Well I dont think putting a boat anchor in the front of your rx is a wise idea either. These cars are unique for only a few reasons their powerplant being one of them. Don't butcher the car if you want a v8 in a tiny car put it in a geo or something.

There needs to be a V8 corner in this very Forum so the mods can simply move these painful threads every time they pop their ugly boat anchor heads....or maybe find a way to ship the whole thread directly to the V8rx7 site....;)

I personally don't like V8s in RX-7s, but to each their own.

I was just saying that some V8s are nicely balanced, and that Lexus is a good example of such.

I'm still impressed by their now 12-year-old publicity stunt of pouring champagne into a pyramid of glasses balanced on the hood of a Lexus (with engine running!) and not spilling a drop...

Try THAT with a Chebby!

how do i install NOS?

is it hard?

and how much do they cost average.. 50 shots..

Well, the NOS most of the time,,comes as a kit. JEGS is a good place to check, price ??? i'd say a good system would go from $ 500.00 - $ 600.00. I guess your a 12a/nikki ,,right ?? there is a plate that goes between the carb. and the intake. it's got holes in it ,and the intakes studs hold both plate and carb. in that plate there are small nozzles that spray the NOS and it mixes with the air/fuel

Isn't there also some sort of fuel solenoid involved to provide the additional fuel that actually produces the horsepower increase?

Say what you want to... you can build up rotarys cheap... bottom line... the blocks are cheap... good core, gasket set, seals, are not that expensive... it all comes down to how much research you have done... the majority of the money that goes into a rotary setup is a clutch b fuel c traction d turbo comp... the same as any other turbo car... the motors are cheaper as long as YOU DO THE WORK YOUR SELF... running a rotary also saves a BUNCH of wieght... if your not running alot of nitrous or alot of boost on a 12 or a 13b your not going to get outragous hp numbers... alot of people blow up motors BECAUSE THEY LACK THE ABILITY TO TUNE THE ENGINE WITH THAT MUCH OXYGEN GOING IN IT... go buy a 302 if you want put it in it... or save your self a couple hundred lbs and put a turbo on the car... tuneing cars isnt easy... not always real cheap... the great storys you hear about people doing v8 swaps in rotarys are becuase THEY HUNT FOR DEALS AND JUNK YARD PARTS!!!

oh yah I have about $1200 into a moderatly moded na 13b 1st gen... the deals are out there MOTIVATE YOUR SELF SAVE YOUR MONEY AND DONE HESITATE... if you do THE PARTS WILL BE GONE!!! This is christmas time and tis the season to buy cheap parts ;)

of coarse there is, and bottle,and buttons,and fuel lines, oh,,and fuel pumps, i just wasn't going to get into it,,to much

Read this archived write up from the 2nd gen section to see how Nitrous Oxide works on a rotary.

https://www.rx7club.com/forum/showth...=nitrous+oxide

I sold my 84 GSL-SE to but a sweet 90 Mustang GT. I love the GT and it's easy to work on and understand, but I missed the "R". Anyway I just picked up an 85 GSL yesterday for a great deal. I love the rotary and always will. Dont ruin a nice RX-7 with a small block. If you want a Mustang or camaro, then buy one. I missed the sound and smell of a wankel, so I went back. I will keep the 5.0, and the "R", but would not transplant a smallblock motor in the rotary. There is something to be said for 100HP per litre in old technology.
