After all the trouble I have had trying to get this damn thing working, to no avail, I have decided to put in a 5.0 from a donated lincoln into my RX7. The money it would cost to make the rotary viable again versus the money it would take to just drop in a 302 just seemed to make sense. say I spend about $1000nto rebuild the RX I would still be left with, what, a 150HP car. As opposed to spending about 6 or 7 hundred to have an over 300HP beast, with torque I might add. It saddens me in a way though because I really liked the idea of a rotary, but sometimes common sense and practicality have to take over. What I figure i'll end up with is a really fast and fun car that handles well. I just wonder what the rest of the forum thinks about this decision. Will I be an outcast, will I be herealded for my ingenuity? I will however be one fast Mo-Fo who will take pleasure in leaving heavy old mustangs behind with one of their own weapons https://www.nopistons.com/forums/pub...IR#>/devil.gif
Rather evil, dont you think |
if you want to go ahead but its ALOT OF WORK! most of the v8 rx7's i've seen look ghetto and rigged up. i would just keep the rotary. it would be less work https://www.nopistons.com/forums/pub...IR#>/smile.png

It will not handle good.

Go for it. My brother has an FD and a '88TII with a Chev 350 V8. Kool car and lots of low end torque. Check out Granny's for the adapters needed.

It will not handle good. |
From what everyone else preaches about the ratio and what not,they say it will mess it up but who know,GO FOR IT !
If things dont work out with my setup I will end up puttin a lil somthin somthin in there;) |
Go for it! :thumbsup: If your lucky we'll still talk to you. :tounge: Just kidding. Keep us posted on how it goes. I thought about doing the V8 swap, but then I decided to keep it rotary powered and make my car fast the expensive way. https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

but hey its ur car do what u want.
thats just my 2 cents p.s why fix what isnt broken? |
HA! it is broken! Thats why I got the car free, the guy who owned it got tired of constantly having to repair it so when it finally gave up the ghost- I inherited it. And I did WANT to keep it Rotor powered but I'm more worried about cost effective fun. The way I think about it, I could spend 2k trying to make it a fairly operational, comparitively slow, non-turbo car... OR ...spend about a grand to have a torquey tire roasting powerplant. The V-8 was free too by the way. The choice became obvious to me as I spent three weeks trying to make the tired 13B even start-

then go buy a mustang if u love v8s so much
|
:madgo: Lets get this straight- the V-8s have been an icon of american motorsports since before you were born I'm sure. And its not the Mustang that I care about- actually, I loathe the sight of them(and most other american cars- sports or not), but I can't deny the fact that the swap I'm looking at only makes sense- because I'm on a limited budget. Sure I could spend the time and money to get a TII setup that would be fun as well. but I'm looking at about the same cost as just rebuilding the RO thats in it now. I think the difference between myself and "bigtime" is that I'm not a car nazi, I can deal with the integration of the species. THIS IS THE ***RX7*** ---and--- ROTARY forum, correct? It's still an rx7, just with a bit of a heart transplant. Same animal just pumped up on steroids a bit. :yinyang:

I also like how one of the admins edited your less than intelligent comment you posted earlier-
Thanks for keeping things intelligent. |
it wont be an rx7 it will be a px7
thanks vosko!!!! hehe i just had to let my aggression out at least ya didnt ban me or something cuz i know it was rather harse |
PX7????
Pony X7 ? |
R = rotary engine
P = piston engine :smilewinkgrin: |
OHHHHH, now it all becomes clear...
:smilewinkgrin: OOOO OOOO that means I should get one of those windsheild stickers that says PX7 realllly big! |
Yea just trim the leg off of the "R"

Not to be a dick or nothin, but the name of this forum is NOpistons.com https://www.nopistons.com/forums/pub...IR#>/smile.png

Man I love how passonate some people can get about cars. ha hah a. Lets just say for the record, many other cars have been converted to rotaries from stock piston cars then Visverse. Now thats flattery! Hypothetically how much aggression would there be if rotaries were in Chev's as the concept Corvette in the '70's actually made production? Ah, I don't care much, Ford and Mazda are together now, so you might say Mazda Mustang and Ford RX-8? LOL! GOBALIZATION!!!!

no mazda will be one again!!!!!!!!

What year is the lincoln?
the Lincoln's where not full power Mustang HO V8's Should still be around 180+hp and about 270-290ft lbs of torque stock. If it is an HO it should be around 225hp 277ftlbs of torque. Dont see why not to do the swap. In my idea it would be the best of both worlds! the Sweet RX7 body style and the power and simplicity of a readily available V8. Plus the uniquness it gives the car. Why not put 2 cars that dont run well into 1 car that would be pretty damn quick? I say go for it. This may be nopistons.com but this is still an RX7 site. Rotary's are cool motors and I like them. But the fact is the last time I looked a 302 (5.0 actually a 4.9) is a lot cheaper to rebuild and service. Could be a fun and very fast project as it is not hard to squeeze a fair amount of power out of the EFI 86-95 HO 302 motors. Hell on my car alone right now I have about 15-20hp being held up by the cooling fan and the rather lengthy and constrictive intake for the motor which I will probably remove sooner or later and replace with a CAI. Plus remember my car is a bone stock GT convertible fully loaded and is capable of running low 14's stock... in a HEAVY car. Plus if I pulled up to a stoplight and an older RX revved at me and sounded like a V8 I think I would be prepared to either get my butt kicked or be in for a very good race! Hey guys dont dog him because of what he wants to do. you dogged me some but he is still an RX fan so show him some support. Go for it man! oh and a thought I have been thinking some about is this. an 86 or whatever body and use a 3.4 Yamaha developed Ford V8 with a 5 speed. Very unique V8 with a high rev capability. Also 235hp stock and a pretty light and compact V8. It is only a 60 degree V8 instead of the industry standard 90 degree!! |
where the heck would you get one of those?
|
And by the way it is an '88 lincoln- and by the time I'm through rebuilding it, it sure as hell won't be stock and its going to take forever as far as I could tell. I can't wait until I get my tax return- I'll actually be able to get some big stuff, probably heads, Edelbrock maybe?
|
The V8 is going to add about 250 lbs to the nose of your car, plus raise the center of gravity. IE: totally change the way your car handles. Your front brakes probably won't be up for it either.
Strap a fat chick to your hood and go for a ride. Then decide if you want to complete the swap... https://www.nopistons.com/forums/pub...IR#>/smile.png Personally I'd just find a ragged Turbo-II doner car and stuff that motor in there. BTW. The Ford/Yamaha 24v/V6 motor mentioned in someones post (if this is from the SHO Tarus is one hell of a motor (and light)... Problem is it never had a 5 speed bolted to it and uses some odd ball bellhousing. I believe the Aerostar/Ranger trans will fit to it, but can't handle it's power. |
true the motor never came with a 5 spd. But it is a good motor and can be easily modified for power seen a few of them around my area... one running mid 13's!! I know a machinist that can do bellhousings. He made one for one of his cars. He used a Liberty 5 speed (not jeep liberty) and bolted it up to a GM 502 crate motor... lol in an 1800 pound car!!!!
oh and on the heads.... Edelbrock are good but look into Cannfield or TFS heads. |
