I tried. I couldn't get it to fit.

That setup is kicking ass on the Hayabusa though. ;)

Kennedy Engineered Products makes adapters to plug damn near any engine ever made into a VW or Porsche tranny. 905 gearboxes are pretty popular as they're cheap and reasonably durable.

Then again, so are Sooby gearboxes, and they have synchros that aren't made of polished marble.

yer goin about this all wrong boy. ya gotta rotate that thing. 90 degrees or so. then you can get half the plugs while under the car, and half when you open the hood. :laugh:

18psi is the official pinata ninja master. you put up your swap pinata and he knocks it down with one swipe. unless its a v8

what do u say about this?

does the reverse exist? I would like to put a vw tdi motor in my miata. i would need a 300ft/lb capable gearbox that could fit a vw.

Proof that the boxer engine will fit in a Miata:

After proving the boxer engine will fit, I went a head and tested a couple other theories I had in mind:

Cost and complexity. Ever looked into the electronic controls on the M5 V10 and the M3 V8. Be a bitch to get it all to work. plus its still a pretty big engine for a V8 due to all its gadetry and DOHC.

Could get it done better and cheaper with an LS (and I hate LS engines).

I remeber back when the M5 V10 first came out all the ricers where loving it because of the 100hp/liter ( ricer math :facepalm:) but the LS7 was both lighter, smaller, simpler, cheaper, and provided a better torque curve. It was more power dense.

If you wanted a similar power band to the M3 V8 do a small cube LS and optimize it for 6K-8K rpm. And dont say an LS based enigne cant take the RPM, there has been a 408 at over 10K rpm. (fastest N/A T56 car)

Hey guys I wanna put an iron duke in my miata because I heard non-counter balanced cranks are super light, so it should be able to rev high? do you think it wil fit.

a serious discussion? kickass. omg yes. the m5 uses ionic sensing (since the saab patent expired) and i'm not even sure what other crazy stuff is going on in the stock ecu of either motor. buuuuut, i was talking with the guy who does a kit for putting the e46 m3 motor into a e36 chassis, and he is using a DTC-S100. http://www.dtafast.co.uk/S_100_PRO.htm when i talked to him a year ago, it had a generation newer hardware over aem, haltech, etc and had the cpu cycles to control the variable cam timing hardware.

i'm wondering if it could get it done on the s65? (or the f20c for that matter)

yup thats me too, even now. and your right, the LSx is all of those things. it blows my mind that a 1950's american design is that good. but it is (even if i would never put one in my car).

i would also highly recommend to anybody to go to see the 24hrs of le mans. standing on the side of the mulsanne straight as the v8 powered cars went by at about 215 was really effing amazing. u can even get crepes and watch the race :giggle:

In for Jesel engineer comments.

I would still prefer the M3 I-6 over any other V-8.

BenR 11-09-2010 12:03 PM

If the question is about doing a motorswap and doesn't end with Merlin, you got bad advice.

if i'm going crazy like that, why not get a 2.4 F1 spec motor that revs at 18k limited and still puts down 700hp?

Reverant 11-09-2010 12:16 PM

$27,700? I better get two or three to make sure I won't be getting a bad one out of the box.

Q: Why has no one done a boxer swap?

A: Because it destroys lives and tears apart relationships.

yeah, i've always been a fan of panty swaps. boxer swaps notsomuch.

CPSmith 11-09-2010 10:28 PM

While we're at it, BMW S54 swap. DOOOOOO ITTTTTTT

Faeflora 11-09-2010 10:41 PM

What I want to see is a car with horizontally mounted motors, one for each wheel. Plus one for suction ala chapparal (sp). Plus one for lift so that way you can have zero weight which = infinite accelleration zero to sixty in zero seconds.
