Since you don't want to hear the 'basterdize' crap anymore...

The rotary power band I think is smoother than any big v8 grumble. This is why I feel its a better motor for the car...

Just think you used to be able to freely rev to 7500 or 8000 or watever now your gunna be shiftin at 5k or 6k maybe stretching it... And Don't try to wind it out, cause you won't make any mo' power and you could damage your 'Rods' or 'Valves' or 'Pistons', or 'Crank shaft', or 'push rods', or 'valve guides' or 'retainers' or 'valve springs' or 'rockers' or 'timing chain' ect.

To me its kinda like your putting bowling shoes on a basketball player...

Good luck w/ your v8... grumble, gruble, grumble....

I'll enjoy my 13bt... Braaaaaaaaaap, Braaaaaaaaaaaap!!

 

I agree with you Nick, the rev's on a rotary are simple insane.
I'm not sure if there's a way to stretch the powerband on a piston
to even top it at 7 and a quarter which is what I really want
without putting a rod through my hood. I honestly am scared
too at simply 'how many' parts can go wrong in my engine, it's
had me seriously paranoid about it since I started thinking about
it. Thanks for your 0.02c man, great post.

And **** yeah I would! I have wet dreams about a 20b TT Firebird eating a Corvy.
I would totally rock a mullet and a three rotor Musclecar. Hell it's been done
to death but I had a 510 with a 13BT.

 

u better grow up pal. driving a quarter mile at a time is for ppl who say "my car can run a blank blank quarter mile how bout urs?" watch out for that guy. mr. 4L60E over here, whats the point of having a sports car if it has an automatic? rx-7 = sports car btw. get over urself mr. v8, just cuz u saved ur 7 from a scrap yard doesnt register with me at all; thanks for saving a dying bread but leave it to the fair weather enthusiast to swap a v8. shouldve turned it for a profit and gave it to a true enthusiast. and it sounds like were all close minded here so b4 u point ur finger at me point it at ur self

 

now dont get me wrong im not entirely against v8 rx-7's. i just am against ppl thinking its the better swaps to do. i actually have a friend who is in the process of building cash to do an ls motor swap. i just dont think its the best thing to do; whatever you wanna do with ur car is fine by me. just makes my car more unique.
i think its cool if you've tried out the rotary scene b4 but just wanna change it up a lil bit but to come a long as a newcomer n throw an old pushrod in one, tisk tisk

idk about lotus making a rotary but i do believe a few german companies made a series and russia had some too i think.

 

**** why has no one mentioned the concept 4 rotor Corvette from the late 60s early 70s? when the rotary was building its popularity

 

my point was... i dont care enough to care...

LOL... i dont care enough to care... still... I dont even know the difference, thats why im on a rotary forum.

I disagree.. they might show excellent craftsmanship, ingenuity and hard work... but at that point it ceases to BE an rx7... ( rotary experiment 7) Maybe we can reach a compromise and re-badge swapped 7s .... PE-7 ( piston experiment 7)


Rhetorical question right?
Ive heard that philosophy before also..... And yes a "true purist" wouldnt touch anything, sure, but im just a rotary engine purist.. As long as its got rotors... Thats all I care about. YES, built what you want... just dont expect everyone to see eye to eye with your acomplishments, or respect your quaility of work. Personally seeing a V8 in a rx engine bay makes me wretch. Not cause i hate pistons ( my volvo eats a ton of rotaries for breakfast) ... but because I love the rotary concept so much! It was my open mind that got me into them in the first place.

Hey wasnt that a mid engine as well... Fumihiko has a great article about the 2 concept models that were engineered... pretty cool stuff. Yeah i said it... EVERY car should have a rotary engine! ( humor) Like you said tim... opinion ticks folks off... especially mine.. sorry guys!

 

Geez you guys. Leave the him alone. It's not like he'll actually get it running.

 

a crap load of different manufactioner have had some sort of a rotary concept
citroen, chevy, benz,and a couple others.
not to mention suzuki and norton putting them in bikes....

 

way to go its going to be the same swap i got and i love it ha what tranny you going with? only difference is mine was from a 96 z28

 

Supposedly a gentleman at the BL Autzone has one... Id pay to see it.. then id pay more to ride it.

 

9k+ is absolutely possibly with a V8, the question is..... for how long? how much do you want to spend? and finally is it really necessary?

I could go into details, but I know they fall on deaf ears.

 

pics or ban!

 

yeah Tim that's a good point I remember reading a lot about that when I
was first getting into rotaries. At one point in time there was a lot of diff
car companies looking into making a rotary vehicle, but it gradually died off
and only Mazda carried on the torch.

Your right, it's not the best swap to do, there's a lot of problems with it from
the get go. Doing this WILL let me spring board into different piston engines
in the future though. I honestly wouldn't mind trying several engine configs
to see what really rocks me, V8, S6, & 20B are all things I haven't tried and
would like to in the future. Oh and a 4 rotor setup, but I haven't won the
lotto yet unfortunetly.......

+1

I'm listening, don't worry. And deaf ears are the people who wouldn't try
something new in the first place, so nop loss there.

Well last night I found a DIRT cheap warrantied (90 days so it won't matter)
high comp LS1..... 800 buxx! I figure I'll try out a T56 first, since there a dime
a dozen, and maybe cut that back later to a close ration 5spd. You're more
into the V8 scene than I am though, what's your recommendations?

Keep in mind that I want to keep this as an AutoX car!

 

Take pictures of the build in progress!

I had considered the LS swap for myself, but I wanted to tinker with a turbo Rx7 first. Now I don't have an Rx7 and probably won't until Steph and I get a house. I miss my sports car...
I will get another FC though!

 

EHIME ,

Mad Props on doing what you want to do with your! If people dont like it **** them. Simple, 1.3 rotary in rx7 good, not reliable but good. Piston motor in RX7. Relaible, More power to weight, Anyone that want to run there street race ready RX7 against my Soarer 7 ... Three words " Bring that **** ". Well see who's car blows up first .... .. If owned about 25 RX7 with rotaries and have spent over 20,000 dollars in rebuilds and new oem motors from the dealership.. ive had nothing but problems with rotary's.. Soesnt mean i dont love them but its more a love hate relationship!!! Anyways, that LT1 swap will be bad ***.. Mad props on doing something different no matter what any of the haters thought.. Good Luck and if you need help and i can help you, please let me know....

Yeah Its got a 1JZ GTE
What!!!!!!!!!!!!!!!!!!!

 

my opinion, id feel dirty too, but logically it makes more sense. cheap, fast, american, haha.... sometimes what makes you happy in life is doing the wrong thing, or taking the harder road. if you have no rotary pride, then **** it!!! go LS1!

 

Ouch, whoever said that?

 

I like this quote, "The rotary is not a "better" way to make power, merely a "different" way to make power."

Some of us aren't trying to stick the bigger torque monster motor into our little cars to be fast... Some of us like to be special in our own ways...

Good luck w/ ur V8...

 

ignore the haters, they know not what they do... (that goes both ways! i dont like to see people hating on rotaries either)
i didn't abandon an epic rotary build, wasn't afraid to tune an RE, etc. I just wanted to build a car for fun with the parts i wanted, for my own amusement. so far i'm more than happy with the outcome. i must say tho i'm getting very tempted to spend money... 420whp for another 1500 bucks. just a little concerned with smog at that point.
anyone in portland area feel free to catch a ride and see 1st hand how much a lumpy stone age (2002) american engine ruins your car.
autocross at PIR on the 10th @ 9am!! you better believe im racing.

 

going SBC-350
bottom end: 4-bolt mains block, forged short throw crank( for a 267 chevy?) forged rods(Ti?) & pistons, ARP fasteners. in essence, make a smaller displacement engine by means of a shorter stroke, this reduces piston speeds and stress on the rods.
Top end: strong valve springs built to take 10K, Ti Valves, ported heads, small combustion chamber if it's staying NA. heads ported to flow for a larger engine @6-8k will flow as well for a smaller engine at higher revs.
exhaust about 1.5" LONG tube headers... keep exhaust velocity up.
intake- short runners, port matched... possibly a sheet metal manifold.

thing to remember- as RPM increases stress on the components increases exponentially. will it rev to 9k+? probably without a problem.... you probably only take it there for a second at most. will it make power there?... depends on the build, cam, etc.
the best people to talk to about a high revving engine is circle track engine builders.... NASCAR engines routinely go to 9k( normally for short times), but they don't last long there and they aren't cheap to build.



800 for an LS1 is dirt cheap. how complete is that?

the reason the T-56 is popular is the .5:1 6th gear, it allows you to cruise on the freeway at a reasonably low rpm, and great efficiency. due to the final drive ratio of RX7's, it helps, but 1st, 2nd and 3rd gears go very quickly. additionally they can handle a 450 Hp/tq LS1, but they too wear & break, but can be built to handle more.
I wouldn't say they are dime a dozen though... they are available, but usually cost $1500+

 

Josh truthfully you're one of the main reasons I'm swapping over,
but shh! Don't tell anyone, lol. I followed your car on V8 Forum, u
seem to have it built up for AutoX too. Just what I was aiming for.

Complete longblock with high comp numbers, its from a wrecker, and he was impressed
enough with the numbers that he'll stand behind it and warranty it which is unheard of.
Includes all accessories and ECU, harness is cut and mangled though so I think I'll find a
new one. Looked at the engine last night and you can eat off that fvcking thing....

I looked close at it and it's the engine they produced (last models I heard) with a LS6
TB and intake. Lucky lucky!

The wrecker next to them have a T-56 out of a Corvy, miles unknown, condition unknown.
This also has a LS-1 hooked up but the guy wanted 55 hundred for the package, included
everything. Had a full front clip from a Corvy (C5?) 03. The price was up there and w/ cond
unkown I think I might just try to buy him out of a harness and trans if I can get a reasonable
price for it.

With everything falling into place like it was ment to be....
I'm getting the jitters.

 

im just glad that all these muscle car enthusiasts are finally realizing that its a lot more fun to put 400 horsies in a 1 ton car over a 2 and a half ton car.

 

the best engine for the swap is a camaro/firebird engine. oil pan fits like a glove, accessories are in the right place an throttle cble hoofs up to teh RX pedal w/o mods usually. easy way to tell a LS6 is there's no EGR going into the top of the manifold directly behind the throttle body.

03 vette? they had a transaxle in the rear with a torque tube running back to it.... won't work. best T-56 to get is out of a 98+ camaro/firebird, possibly a newer GTO('04+)...... be sure you KNOW what you're looking at.
