why are the worlds fastest RX7's powered by Rotaries? How come all these guys with the so called V8 rx7's never seem to get the car off the ground?



I dont like to see any rx7 brought to the level of trailor trash like this. Rx7's were meant to have rotaries not big block V8's. The one thing that makes All Rx7's special is the rotary engine.



An Rx7 with a Chevy V8 is a Camaro with a Body transplant rather than an RX7 with an Engine transplant.

if it works why mess with it, its like brittney spears gettign a sex change. leave it alone.

I like V8's, they have their place, but just NOT in an RX. https://www.nopistons.com/forums/pub...1047683329.gif

Yea, I'll go with that one.

This **** is so ******* stupid. If you didnt like the rotary engine why did you buy a rotary car? Its not like its hard to find something with a piston engine in it or are you as dumb when it comes to that as you are with your rotary engines? I mean its not like ALL cars are rotarys and you can barely find piston engines. Its the other way around save something for the people that truely love and have never had the joy of owning a rotary. Its people like you monstermazda that make me sick becuase your to stupid to realize anything or try to learn something new. Remind me to never read this section of the forum again.

i totally agree. a rotary is what distinguishes rx7 from the vast pool of inefficent pistons engines . Hence the name of the website "No*******Pistons.cum" https://www.nopistons.com/forums/pub...1047683358.gif

My thoughts exactly.

calm yourself people... it is HIS car and noone should knock him for it, may cause a complex or something. unless something is being cut heavily from the rx, the value will not go down, the engine can be transplanted back ya know? if his car was only 900 then what is this about value? the wheels on my bike cost more and you get more fun out of the car!

88RX7annived 04-08-2003 08:18 PM

Its not a bad idea to do this swap. Its cheap, performance parts are easy as hell to get and cheaper than the ones for RX7's, its different-which is what almost every car guy wants there car to be from everyone else's. As for value, he's not selling it, he's going to use it and race it! Its not a discrace, its actually a wise decision-He has a bad engine that would be expensive to rebuild and for the same amount (or less) he can get a LOT of POWER out of it, while if he just rebuilt the rotory he would still have to do more to it to get the same level. I give you props man, keep us informed on how it goes and what setup you use. Good luck! I'd love a ride!!! https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...IR#>/bigok.gif

almost every major manufacturer has had a rotary development team over the years, and if they did not, they are now owned by a company that did at one point. some people think that a v8 does not belong in an rx7, well, does that mean a 13b does not belong in a datsun 510? no one gets mad about that **** who the **** cares? too often, too many people get too up tight about that ****...it is childish to get "flaming" mad at someone on the internet over something soo trivial.



like the above states......if the owner likes it..............and so on....





as for the 4 rotor corvette, if anyone has seen it in person, like in the museum in bowling green, KY......the thing is HUGE......

A Datsun with a 13B is more of an RX7 than an RX7 with a V8.

RX7 13B 4 UR AZZ 04-13-2003 08:21 PM

ughhh!!! ive been reading this and i was thinking of doing the V8 conversion till now. My 88 SE has an auto tranny now today it started slipping and staying stuck in 2nd and I said well for the money im going to spend putting a manual tranny in my car(Hydraulics, Flywheel, tranny, pedal, clucth) I could probably do the V8 conversion and still have money left over. The thing about the rx-7's is that everything costs an arm and a leg like the Idel control valve $599 that is not fun. for $599 i can get a whole 350 engine. Belive me guys i love the rotaries and there potential in infinite but evrey thing is so expensive. I bet i will at least spend $1500 on the tranny swap at least to put my car manual and that will only make me a little bit quicker now put a fresh 350 or 5.0 V8 in there than BAMN ! ! ! ! Im one of the cars on the street not to mess with. If worst comes to worst and i see that the tranny swap will be to much money V8 she goes.



BTW any one got any estimates of how much a tranny swap costs???

RXciting 04-14-2003 12:05 AM

OK... one i got 2 silables for all the people knockin on this kid.. "De-Caf"



Relax.. he's sticking a V-8 in his RX-7 even though after the V-8 swap it will ciese to be a TRUE RX-7 until a 13b is re-installed... Quoting someone else ,who i can't remember to to lack of sleep and excesive alcohol consumption, it's like giving a corvette a body transplant since i guess the engine, powerplant, would be the soul of the car. Another comparison would be to take Arnold Schuatesticlies! ******* howerver you spell his last name's mind and sticking it in Bruce Lee



It's similar, although not the same, and this is just to give some people an idea of what i'm talking about since tomorrow i'm sure i won't have a clue, this is similar to someone having a 2nd gen and sticking a 3rd gen engine in it. In this case it's still an RX-7 it's just not a TRUE 2nd gen it's like taking Bruce Lee's mind and sticking it in Brandon Lee (that's his sons name right?)

similar but not the same.



So by saying this should a stuck up pure blood doesn't like 3rd gen 2nd gen owner start talking **** to the guy that did the 3rd gen engine swap

Look... I've been thinking about doing a swap. The costs do add up if u want to complete a v8.



engine:



block, heads, pistons, lifters.... if you get an old engine ur gonna have to check all that stuff out, and it may need machining.



mounting kit:



the kit is gonna cost u like 500 at a minium... personally i'd like to have air conditioning and that is expensive.



but the transmission:



a Borg Warner WC T5 tranny will run you alot. Its not a typical chevy tranny. They are definately not as common as the automatic powerglides or T350's. The trick w/them is they aren't rated for very much power so its possible to destroy it w/torque easily. The other concerns... bellhousing, shifter, etc... It all adds up. If you want to go six speed (which would be amazing) it gets really expensive.



Cars cost money, I don't have any. If you can afford it, and you really take your time balancing the car... GO FOR IT!!! It'll be fast as hell and sound amazing. Nothing like a v8 in the morning, but balancing it is gonna be a pain. check weights on each wheel, cuz its more than front and back distribution. side to side is where it messes up the weight mostly. Thats why people find the major loss of handeling.



Goodluck, i'm still not sure which way i'm going to go.



if you do decide to convert it... I want pics.



peace,

Personally I like the idea of the swap. I'm starting a business up and I will need a car to showcase the product. I'll be attending import and domestic car shows. With that in mind my RX-7 won't be taken seriously at some of the hot rod domestic shows unless I do something that will attract the attention of that crowd. Dropping an LS-1 w/6-speed would definetly attract attention to the car then I can show them the product I'm selling(custom leather seat covers if your interested). Now at events like NOPI I wouldn't dare take a domestic car or my wifes SUV to it. My RX-7 is still the best choice even though it has a 325HP V8 in it I can keep the hood shut unless someone ask and then I'll suprise them.



Now you can call me a traitor all you want but I know I'm not. My autocross car is still rotary powered and I'm considering buying another one(convertible).

my 85 conversion is on grannys website under len hendersons beautiful 85 with ford 5.0 and aod guys i loved my rotory engine i owned car since it was new got over 300k miles from it. one of the reasons i made conversion is that parts are getting harder to find another reason is 362 hp with 301 ft lbs of torque with my overdrive tranny that i built i am getting 28 miler per gallon on hiway and i can blister both rear tires. presently building a 393 stroker 550 hp and 200 more on the button zoom zoom https://www.nopistons.com/forums/pub...DIR#>/ohmy.png
