E30 M3 + E39 M5

[Imre]

M3 E30 engine is replaced by more powerful M5 engine.Should be very fast on straight line but i think not as good going through corners.

oh la la I like it. Interesting idea, I never would have thought of putting a newer V8 in an engine bay designed for something with half as many cylinders. Its a great idea :twisted: It helps that the E39 M5's engine was such a masterpiece

Hopefully they'll do some suspension and chassis tuning to compensate for the big weight gain...

[TT]

I fear it is just too heavy at the front, but well, it still is a cool idea and for sure there are not many V8 E30 ;)

[Sir_GT]

Why not supercharge the E39 V8 and plop it onto an exige? Imagine a super lightweight mid-engined V8 with Lotus handling.

Yeah it looks like the engine is almost completely in front of the front axle... gotta be horrible for weight distribution, not to mention the polar moment of inertia

But hey, it is unique

[astonmartinandy]

Lol yeah it definitely is unique, but i have to agree with the problems of weight distribution... looks like a recipe for chronic understeer to me :?

[bmwmpower]

hell car, imagine that power in the corners only one small step on gas and your back will be in corner first, great but better will be M 3 E46 engine in that or 3.0i V6
231 hp, hartge H50 is also brutal

...I think if they were going to do that it ought to be the in-house 3.5L turbo V8 from the now-defunct Esprit...or maybe that itsy-bitsy 2.6L Powertech V8 which is currently due to be used in the Radical SR8....at least 383bhp and around 210lb-ft. Imagine that engine....just imagine it... http://pistonheads.com/news/default.asp?storyId=9293

great but better will be M 3 E46 engine in that or 3.0i R6

Pretty cool...I bet it sounds a whole lot better with that V8 as compared to the I4 it came with. :D

[Anonymous]

Mmmmm. . . I just picked up an E30 too. Not M3 though =(.

[findleybeast]

I wonder how much development and cost it took to shoehorn that big V8 in there?

[5vz-fe]

I afraid not only does the weight distribution goes shitty, the chassis might not be ridgid enough for the twisting power of the M5 engine. I guess it's not a good mod. It would be better off turbo charging the original M3 stroker engine.

[Skyliner]

Is the E39 M5 V8 not a 90 degree? There sure must be a lot of cutting out metal to make space for the exhaust.....

A forged S14 would probably have delivered a least the same performance on the straight, but would have been much better around the bends...

Some crazy german even made one with an Alpina V12... Have a look at the pics

Found this at e30.de..... check it out, lots of nice BMW's....

[skituner]

personally i think that takin it to far
going from a 4 cylinder to a 8 it just lookin for attention but who knows maybe this will live at the drag strip

[Ford Capri 2.8i]

I like those sort of invention as Dani does, ut i think that the car will be difficult to balance overall, and therefore it will be difficult to get used to the car when sliding it or for practising the sideways, and it wont be a great fun as the stock E30 M3 as a result IMO

The car will be astonishing in straight line though

[SilviaEvo]

that would be astonishing at the performance if it could handle that much power with ease but it must be next to impossible with that gimoungous sedan engine in there

[findleybeast]

does anyone know of the actual weights of the two blocks? The E30 engine is older, so it may be heavier than a modern 4 cyl and the weight difference may not be as much as you'd expect

[noosee]

I love it :D
So much torque in this little light M3 :shock:
Maybe it will not be the best handling car, but the most FUN :D

[SilenCe]

I'm not shure, but i think i have a vid of the V8 doing donuts!
The sound is amazing! But i don't like the cars who don't have the original engine in there.

when you can hit a v8 in an exige, do it,
it is a tight fit for the I4 as is

[xxleasxx]

not the most imprssive e30 swap that ive seen but definately one of the cleanest..
TTV12 M3 E30 > E30 V8...

[ESR_balla]

I willing to guess that the engine add around 100 more lbs to the front. Remember, the S14 was cast iron, not exactly light. And for 400 lbs of torque, I think thats a great trade off I could live with. :mrgreen:
