Engine swaps we like and hate.

ok for the guy who ripped on KA24s, chill. the 240sx has a better flowing head that can support some real numbers.
completely stock internally, ka24, 326whp @12lbs of boost, 139,000 daily driven miles, low 13 second timeslips on street tires.

oh and sr20 in a supra isnt so bad, sr is waaaay lighter than the bigass 2jz so for better weight balance, ect. it makes some sense. especially if you really dont need 1000 hp.
like chris forsberg's old drift Z with the sr swap.
or the fact that toyota supras in the GT500 class of the JGTC used to run a celica 3s-gte...


my buddy has a mid 90s neon with a 2.4L stratus block and a neon R/T head. its pretty fast.

i wanna see a early neon with a 3000gt SL engine in it.

VQ35 maxima motors are starting to appear in 2002-up sentras.

My honest opinion on that is that Nissan has always done a great job doing the little things to get HP from their engines. Things like polishing the cams and porting the heads from the factory.

Here's a cool one, how about a Subaru powered by a Coswoth YB engine?

How about a classic Willy's pick up with a Ford big block?

What are you guys kidding, the LS1 is better than the rotary engine in nearly every aspect.

-stronger
-more reliable(apex seals... cough cough)
-has TORQUE
-better fuel efficiency
-doesn't NEED turbos(and if they are ever added it will wipe a TT rx7's ass with a rock)
-not sure about easier to work on, but it sure as hell is easier to find a technician that can fix it if need be
-cheaper to make it go fast

the only negative I can think of is that the RX7s are super smooth, so I suppose if you can't stand a loping car then get over it and stop being a puss.

Yes RX7s can rev to 9000rpms.. but in reality the engine doesn't START until like what? Maybe 4500 rpms? :lol: The LS1 has a torque curve that gives it insane power from about 2000 rpms to redline.

And no, just because it has the "inferior" pushrod design does not mean it cannot go over 5000 rpms :grinno: With a decent selection of valve springs and rocker arms it can see well over 7000rpms. The fact is it just doesn't need to :lol2:

And to negate that argument about the LS1 weighing a DREADED 50-60lbs more than the RX7... Did you know that LS1s do NOT need twin turbos to create power? I'm not positive on how much weight a big ass intercooler, two turbos, and a clusterfunk of piping needed to make a rotary engine "up to par" will add, but I imagine it's enough to justify that this is a null point.

The end :smile:

I think I'd like to see an RX7 with an LS7 (you know the new 427 stroked Z06 engine).

I like the way you think :grinyes:

There's one around here with a a 351 Ford stroked to a 427, and there's not much that can touch it.

I enjoyed my 350 V8 in my X-Nissan 240 SX!




im thinking of doing this swap what all did you have to do?

I think I'd like to see an RX7 with an LS7 (you know the new 427 stroked Z06 engine).

It was talked about on the V8 RX7 board, but the cost of the engine itself kind of negates the cool factor, since you can get the LS2 to 500+ hp for a tiny fraction of the cost of a stock LS7.

And as much as I liked my almost 400 hp Ford 302 powered 2nd gen RX7, the LS series is just the best all around choice.

a Swap I HATE, i absoloutley despise anything but a rotary in an rx-7 (makes the car handle like a bag of ass), and i hate to see such an amazing peice of engineering go to waste by putting something with ONE underhead camshaft in it.

Puleeze. It's been proven many times (on here and on RX7 forums) that that is simply not true, unless the person swapping it SPECIFICALLY was building a drag race car. And in that case, any of the rotary powered drag RX7s are just as bad, right? I mean, they don't handle good anymore, even though they still have rotary engines, right?

As the scale slips and even video have shown, V8 RX7s tend to have identical or better weight distribution than stockers. PERIOD.

Oh, and the "amazing piece of engineering" is simply an 1800s era oil pump modded to run on gasoline. You knew that, didn't you?

rx7= Rotary eXperiment...

What does the name have to do with anything? You think the Ford Mustang is actually a horse? You think that the Plymouth Barracuda is actually a fish? You think the Hyudai Stellar was actually any good?

The RX name was invented for America. The first Mazda rotary car (and the continuing showcase for it for decades) was the Cosmo. No RX anything. Then the Familia got the rotary (which we in the US got as the R100), the Capella (known in the US and Aus as the RX2), and Savanna (which we originally knew as the RX3, but then became the RX7 which retained the Savanna name in Japan for years).

Please, let's not use misinformation as the basis for forming negative opinions.

i hate the ls1/lt1 in a fiero...

then they go out and get a ferrari body kit...who are they kidding....

I think I'd like to see an RX7 with an LS7 (you know the new 427 stroked Z06 engine).

My friends who's a mechanical engineering student at UT of Austin actually knows someone who is doing that. It's def. something I'm going to have to see.

K20A into Lotus Elise, some guy around here has done it, heavenly (And doubtlessly would kick the ass of one of the Toyota powered 135R's)

I like the swap (though it eats up transaxles) but hate the kit. In the new issue of Hot Rod they have a Fiero with an LS6. Pretty clean.

Like - SR20/13B in 240Zs.
Like - RB26DETT in S14 240SXs. (Vette/Supra/whatever killer)
Like - SBC in Fieros. A friend of mine's dad did one of those, was pretty badass, imo.
Not to fond of (but don't hate) - V8's in RX-7's. I guess I'm a bit of a rotor-head, but I think anything other than a Rotary engine gracing the engine bay of the RX-7 is blasphemy and is mollesting "teH chassis". To each his own, though. I always say if you got the money to do it, do it, doesn't matter what others might think as long as you're happy with it. And, what can I say, the second gen RX-7 is more eye-pleasing to me than an F-body, so I can see why muscle guys like to drop their god-awful piston engines (joke) inside the sexy little fastback. =)

Besides, those things must haul balls. There, I said it. But, I died a little on the inside. =P

I guess I'm a bit of a rotor-head, but I think anything other than a Rotary engine gracing the engine bay of the RX-7 is blasphemy and is mollesting "teH chassis".

This is the part I don't get. these are mass produced compromises. mechanical devices designed by people and built on a robotic assembly line. How can swapping out one method of exploding dead dinosaurs for propulsion for another be "blashemy" or "molestation?" They work better than they did stock. They have no souls, and they have no feelings.

And they aren't even rare or valuable (when dead ones are under $500, nice ones can be had under $2500, and rotary enthusaists tell other rotary enthusaists not to pay more than $500 for one that's perfect other than the engine, then how can ANYONE shed a tear for a car that is been lovingly rebuilt by an enthusiast owner? Especially when they've been proven to work so well?)

No one says people have to make them V8s, so why say they have to be rotary?

It was a joke. Guess my sarcasm doesn't translate well into the internet.

Like I said, I have no real problem with V8 swaps in RX-7s. If you have the money to do it, by all means, do it. I was just stating that I have a bit of love for the Rotary engine, if you or any others don't, that's perfectly okay with me. Not like it's gonna kill me or anything. Everyone has their opinions about cars, to each his own.

And, you're right, it doesn't have to be rotary powered, that's up to the owner of the car. Not trying to start a flame war or anything, I was just stating my opinion.

Ok. OTOH, there's no reason to assume that because someone like me put a V8 in their RX7 that they have no love for rotaries. I've owned an R100, RX2, 2 RX3s, a couple first gen RX7s and a 2nd gen RX7 that I autocrossed successfully for a year before doing the V8 conversion (when the stock engine died. And ironically I put the V8 in it because I didn't have the money to rebuild the stock rotary, much less make it have any sort of power...). I've put rotaires in non rotary cars and crewed for both an SCCA rally team with an RX2 and an IMSA RS team that campaigned an RX3 and a rotary powered Formula Libre.

And I'm just stating my opinion when I say that people who make inaccurate and rude comments about V8s in RX7s simply don't know what they are talking about. ;)

I seen Grand National Motors in Jeeps, I thought that was pretty cool
My buddy got a TT 4.0 GN in a 95 Mustang LX....funny huh

Actually saw that at the Buick Turbo Nationals as well as a 67' Camaro with a twin turbo Duttweiler Buick V6, an S10 with a turbo Buick V6, a 78' Firebird Trans-am with one, a Cadillac CTS with a GNX engine, a Metro converted to rear drive (basically a drag car) with a GNX, and about half a dozen RX7s converted as well.

over in Ohio Chuck Mallet will drop an LS1 into your Pontiac Solctice

i saw a 4.6 liter Northstar in an early ninties VW Golf

but i think my favorite is the SR20DET in a Datsun 510.

its just badass

hate: an ls1 engine into any rx-7.....i dont see the point, sure you're makin the numbers, but the extra weight kills it on the track.

Love: a '99 Nissan Sklyine GT-r R34 engine into my '79 Datsun 280ZX turbo....truly an ungodly amount of power.

a swap i wanna do.

I have an 86' AE86 Corolla that hasnt been treated nicely(not by me, mind you) and the engine has all sorts of problems. i want to put in a V6 engine, posibly Nissan, like the RB26dett, or the K series motors.(those are nice) anyone with advice or another suggestion email me. [email protected]

This thread is pretty old, but I have heard nothing but good things come out of the LS1 RX7s. The LS1 isn't as heavy as you would like to believe. The weight isn't effected all that much.

well, the weight may not affect it as much like you said, but in a test between 2 rx-7's (one with a rotary, one with the ls1) the rotary walked away from it in everything, and the ls1 had over 100 more horses and a fair amount of more torque than the rotary. both were tuned by shops that specialized in that particular engine. what did that lead me to believe? the ls1 does weigh more than the rotary, and the weight in the front end messed with the handling, or something of the like.

I would like to see that test, I don't believe that an LS1 rx7 with over a hundred more horses lost in a race against a rotary one with less hp and torque.

Like - LS1 into anything

Dislike - LS7 swaps period, because it's a waste of a good LS7, whereas there's enough LS1s for everybody

Dislike - Rotaries into anything other than an RX-7, why? It's stupid and I sorta agree with the guy saying that he doesn't want a piston engine in his car for the same reason, but for what he said about my engine and my car, he's a ******************-********-*****cker.

I would like to see that test, I don't believe that an LS1 rx7 with over a hundred more horses lost in a race against a rotary one with less hp and torque.

The reason people do this swap anyway is because the LS1 has more power to start with. They don't usually think once it's in they'll mod the piss out of it. To me the FD LS1 got old FAST and I'd rather see cars with their engines get modded.

Like - V6 swap into Geo Metro, because you can't get tired of a 9 second metro.

the ls1 doesnt weigh much more than a standard rotary engine, i saw a test between a rotary rx7, ls1 rx7 and a ls1 camaro, (all had equal power) and they finished in that order in a track test, only because the rotory rx7 had a better suspension setup than the ls1 rx7. i beleive the magazine was sport compact car or something like that.

yeah, the mag was superstreet and i believe the ls1 rx-7 had almost 100 more horses and they did finish in that order. i may be wrong, but thats what i think.

the RB series engines are all straight sixes. the V6s are VG or VQ series engines.

good point, i thought most of the nissan's were straight. but i wasnt sure. but the K series should work, shouldnt it? i mean, it is a toyota engine...

Toyota has a K motor too? I knew that Nissan had one and that Honda had one (though no relation between the two).

good point, i thought most of the nissan's were straight. but i wasnt sure. but the K series should work, shouldnt it? i mean, it is a toyota engine...

K series as in K24DE? as in the engine found in 240sxs?

if that's what you mean, then no. if it's a nissan engine, it's not a toyota engine, is it?

toyota did have a K-series, up to 1998. a 2-valve per cylinder unit.

but the most common swap for putting a different engine into an AE86 is to drop in a 4A-GE.

how bout this...

ive got an old chevy 350 in my garage from my project truck that got replaced with a 383 stroker, and my current daily driver while im finishing the truck is an 88 honda accord... and you guys know where im going with this

the car is only worth a couple hundred bucks due to some dude deciding to t-bone me, so i recon i could cut out the rear suspension, put a chevy solid axle in there, hook it right up to a turbo 400 with the old 350 coupled right up to that. that would be a 2500 or 3000 pound sleeper right there, unless you looked in the window and saw the smallblock where the rear seat should have been

What about my Datsun 280z? First I swapped in a mild Chevy small block 383.

When I blew it up I decided to step it up alittle....

Now my little Z car has a thumping 454 big block under the hood.

Pics and details in the link in my sig. Enjoy.

What do you guys think?

Thanks!!

K series as in K24DE? as in the engine found in 240sxs?

if that's what you mean, then no. if it's a nissan engine, it's not a toyota engine, is it?

toyota did have a K-series, up to 1998. a 2-valve per cylinder unit.

Mazda had a K-series V6. 2.5L KLs in MX-6s and Probes, 1.8L K8s in MX-3s and 2L (KF) and 2.3L supercharged miller-cycle (KJ) variants available in Japan. Alas, these motors can't oil themselves correctly when mounted for RWD applications (many an attempted Miata swap will attest to that) so they're right out for a Hachiroku swap.

Sweetest swap I've seen lately was an S2000's F20 in a Miata. Supposedly a German firm has managed to get a Renesis 13b into a Miata but I haven't seen that one in person. By all accounts the RX-8's electronics make swapping the Renesis a bear unless you can get ahold of a Formula-M ECU.

rotary 510 for real and for sale

I think 350 swaps are getting old. I plan on swapping an ecotec into my chevette

I will like it

Evo owners will hate it:grinyes:

i just traded into a 70 nova ss without a motor and trans. i have a ford 429 and c6 trans im seriously thinking about putting in it. any problems anyone can think of?

i just traded into a 70 nova ss without a motor and trans. i have a ford 429 and c6 trans im seriously thinking about putting in it. any problems anyone can think of?

Yup. Many (but not all) 429's have front-sump oil pans, so the sump will be right where the Nova chassis cross-member will be.

If so, you will need to get a rear-sump oil pan and oil pump from a Ford 460. One from a full-size '70's Lincoln will do.

The rest will be pretty straightforward fabrication. The Ford engine mounts can probably be welded to the Nova chassis, but a bit of fabrication will be required to get the placement right.

The stock exhaust manifolds should work, just get a muffler shop that can custon-bend an exhaust.

The transm cross member will require fabrication, but that should be pretty straightforward. And you will need to fab a driveshaft.

But the 429 is very similar in size, weight and dimensions as the big block chevy, (which of course made it into the Nova) so there is enough room.

FWIW I think my 429 is an excellent motor, free-revving with lots of power. If your 429 was made after 1971, it will have a retarded cam timing that kills power. If so, try using a multi-position timing chain and advance the cam timing 2 degrees. Also, be careful of stock replacement timing sets They all have retarded timing, regardless of the year. The multi-index is the way to go.

i like all those swaps i especially like swaps that are not ment to be.. i own 2 cars a 1972 nissan datsun with stock l24 engine and i own a 1981/MkI toyota supra that is gutted to the bone weighs 1952 lbs and use to have the stock 2.8 with a crappy 116hp just until 3 weeks ago when i got a crazy idea to go and put a vg30dett also known as a nissan z32 motor in it im half way there every one said it was impossible and stupid ha! had to fab new mounts and driveshaft and might have to beef up the rear end seeing that it was only meant to have 116 hp and not 280hp. Now i know what your all thinking why didn't i put it my 240z? Thats becasue its to common i mean nissan to nissan swap whats the fun in that? Now a nissan motor in a mark I supra now thats unique i will be posting my video on youtube in a week or so and will have dyno's and most likely drag it to see what it will pull on a 1/4 and will post some pictures on here if its possible to post on here if all goes well! <hey just because im doing it dosent mean u should to.> (I live by this)

I have a fiero and i dont like the engine- the inline 4. its weak and low revving. has the 5 spd getrag manual. i am unsure of what engine to put in it but my friends have experience with japenese cars and will help me install, but dont want to sway my opinion. another available option is a 4.3L Vortec engine. i was considering the sr20det or a ka24de but have no idea if they will work. can someone help? i see lots of 3.4s/3800s and want something different.

the coolest swap ive heard about so far is the sbc into a Pontiac Fiero. check out www.v8archie.com (http://www.v8archie.com) they were featured on High Performance Pontiac too so they are experts on the Fiero

as far as i know they use the original trans and suspension which is cool

the coolest swap ive heard about so far is the sbc into a Pontiac Fiero. check out www.v8archie.com (http://www.v8archie.com) they were featured on High Performance Pontiac too so they are experts on the Fiero



That is very, very cool!

Would give the poor little Fiero the performance it should have had from the start too.

Saw a 1988 Fiero GT with a supercharged 3.8 V6 out of a Pontiac Bonneville SSEI.

Looked like a tight fit. The guy did LOTS of fabrication to get the engine in there. I'm not really into Fiero's, but it looked awesome and at the track his car almost beat my V8 5 speed Mustang GT. To top it off his car had an automatic tranny!!!!
