What V8 would you stick in your rx7?
 

I am not here to be flaunted by the piston haters, I dont know if i could drop a V8 in my own vehicle, but lets say rotaries were illegal for some dumb reason, what V8 would you stick in your car?

I would love to see someone stick a 4.0 or 3.5 land/range rover v8 and build it up with some non sequential twins.

Or does anyone know of any other smaller displacement v8's that could be available? maybe say a 3.0 v8?

Pomegranate-Blueberry for sure.

I don't see why you'd use a Rover V8 when we've got LS1's sitting around and all of the GM crate engines. More performance, easier to find parts, sounds awesome.

I'd actually like a turbo 2.0L I-4. That way you can get decent gas milage, and some power when you want it.

2 parts milk, 1 part strawberry banana, and 1 part orange juice w/pulp


It's like a magical smoothy.

Even if an LSx swap would be easier, if i had to swap in another engine, it would be a 2JZ or RB.

if rotaries were illegal there wouldnt of be RX7s.

if you want a v8 get a vette, they are nice cars. ill never get you swappers.

Tell that to people who already converted 75% of all the FD's left to LSx. :rlaugh:

Why did you even come to this forum, then?

I'll never put a v8 or piston motor into my car but I was replying to the "if i had to statement". And this thread was in general automotive first but got moved.....

LEXUS V8 NO DOUBT. DOHC 32 valve, smooth as silk, and an unrealistic redline.

Toyota reliability, V8 power, high rpm breathing, pretty much no chance of valve float...

If we wanted a Vette, we'd have bought one. Many of us have dead RX7s that need a heart transplant, and it's cheaper/simpler/more reasonable to build up what we have than scrap the dead car and get something else.

Secondly, the RX7 as a CAR is more than just it's engine. It's a lighter, better built, and for many of us, better looking car than the Corvette and especially the F body cars. I've never understood how people like YOU can't see THAT set of facts.

In my price range, I would have had to have bought a much worse condition early C4 Vette, and they simply aren't very well built cars in comparison to even the 2nd gen RX7. My completed, converted RX7 wth full interior only weighed 2720lbs. That's 300 lbs lighter than a C4 Vette, but with better torsional rigidity, less rattles, better ergonomics and build quality, suspension that was at least as good if not much better, and I thought it looked vastly better than the Corvette. I also already had the car and had invested into the suspension to make it an autocrosser. AND it was worth almost nothing as a non-runner when it died, even with the money invested into the suspension and paint. So it made a lot of sense to build IT up the way I wanted.

Good choice, and what I'm putting in my 1963 Mercury Comet to replace the stock 260cid V8:

hahahahahahaha!!!

No pistons in my cars, that's blasphemy right there.

LS9 with unlimited funds :D

Exactly what I'm putting into it... an LS2 with a T56 combo (should be in the 450 whp range).

^What kind of mods are you doing to get there?

If money were no object?

LS7 to start, but since I hate american waste of displacement, I'd rather use the 6.2L V8 found in a Mercedes CL65

Then again, I'd wait for the LS9 and throw a couple of turbos on it and call it a day.

Define awesome sounding. I admit to being parital/biased a bit but imho my tvr rover v8 sounds far better than a typical mustang/charger <insert yank muscle here>

German V8's FTW! "Only" 6.2 L for > 500 hp. We might get closer to the magical Honda 100 HP/L on big engines!

(F1 Engines don't count)

Screw the v8, just get a 20b and keep the faith. :D
I have to admit though, a v8 is tempting for the fc.

I'd never owned a v8 car until last April so a year ago I would have called you
v8 guys heretics, apostate and blasphemers. I am still much a rotorhead. On the
other hand, having spent a summer with "v8 face stretched backwards" syndrome
I understand why you do it.

I keep hearing this evil voice in my head telling me to take my 13b from the fc and dump it into my fb, take the rover v8 from the 390se and dump it into the fc, get a griff 500 lump for the wedge. I wish I was rich, a nice three way motor swap would be so cool.

ls1 cheap to mod and its a fact they make great power...

Does the original question assume a realistic budget? I ask only because I'd love to have an older 3.5L F1 engine detuned to about 600hp.

100 HP/L only works on small, high strung motors. Honda and other "zing" motors don't scale well into larger HP/size area without sacrificing reliability. I'll never understand the HP/L argument. HP/Lbs is an excellent benchmark, as is HP/mpg, though neither is particularly useful without a reliability litmus as well.

I like Honda engines (though they're not for me particularly) and my Impreza's boxer 4 is a great engine (nice torque and >35 mpg highway is excellent). Mercedes, BMW, etc. all have some great powerplants, though they are often complicated for the sheer sake of being complicated.

Perhaps I'm a rough, redneck individual, but I will happily take a simple, efficient and effective OHV V8 with a nice cam that can still irk out ~30 mpg highway.

As I said, I've nothing against BMW, and would drive a 540 any day of the week, it's simply not my preferred method of performance motivation. There are plenty of points of merit for Honda or any other engine in that "breed" without having to fall to the weak "HP/L" discussions.

Oh, and to answer the post, I'd prefer an LSx blocked LS9 engine. 6.2L, 620 HP. Wait, that's 100 HP/L. ;)

any v8, then race my rotary for some money. :)

except the 9 is boosted......no cheating!

Nono, I was making fun of how a lot of Honda ricers say, my engine makes "100 hp/L, it's a superior engine than yours!"

still, 6.2L for 518 hp and 465 ft-lbs aint nothing to mess with.......esepcially since it's NA.

What's it your rotary and what type of race? I bet I could make it interesting.

i'd race on at autocross for money :) and we're both in NJ :)

the starter of this thread man you need to come over to the beach and see my cars I have a Rover V8 MGB GT, and I'm thinking about twin GT28's for it with a real steel bottom end.

Nah, that wouldn't be fair, 3-rotor engines screw up the handling dynamics of rx7s so he'd be at a disadvantage. :rlaugh:

Didn't you post a while back about moving to FL? Whenever you get here, please bring your rotary and your money... I'll hook you right up. :icon_tup:

Such foolishness, you'd get drug.


mike

OMG, no he wouldn't. Rotaries > ANY PISTON MOTOR, EVAR!

You are such a retard!

How about a little V6 ??? Something like a Buick GN one.. I think they make 250-300 hp !!! RX7 should go pretty good with it :naughty:

stop picking on the 3 rotor ..
speed fab ill be in orlando this year ..hopefully with the car ...do you go to the races ?

i belive turbo tommy also has a nice 93-94 supra .but i dont think we do much autocrossing around here ..

Hell yeah. Let me know when.

ill be ther for the world street nationals ..

I ripped out a mint s5 t2 engine with fresh rebuild (brand new housings too) tuned apexi powerFC, Rb turbo back, greddy fmic, koyo rad etc... for an Ls1.

Why?

Bored.

If you're ever in NC, say SCCA auto x $500-$1000 to the winner?

You guys must not know much about turbotommy rx7.

well me and kukri said in "autocross".

How many motors have you blown?

But, back to the topic. If money was not a concern, I would definitely drop in a semi-built LS7.

hmm.....if money was no concern, I'd drop in the 5.0L V8 BMW engine found in the Ascari A10......625 bhp NA.

BMW N62, w 6 sp manual from a 545i

just love the way that motor sounds..

Why don't you fill us in? :Wconfused

If money were not an issue I'd go with a hayabusa v8. I forget the name of the company that makes it but they basically take two hayabusa motors (its from a motorcycle for those who dont know) and they build a crankcase to join them together.

Umm...I am currently contemplating both a rotary FB and a Olds turbocharged and intecooled rocket v-8 into an FB. I wish i knew which rotary engine i wanted.....BTW, The oldsmobile aurora v-8 is an awesome 4.0 l v-8.... INDY POWER BITCHES!
