nathaniel 5 Report post Posted January 5, 2017 Hi All I am fairly new to these forums but I have been an 86 owner for almost a year now. Recently I've been inspired to do something crazy. Someone put a Ferrari V8 into one of our cars. My question to you guys is do you think it is possible for a V12 engine swap. Specifically a BMW 5.0l M70 V12. Any help, comments, tips or feedback would be greatly appreciated. Don't follow the crowd, be unique. Share this post Link to post Share on other sites
Varelco 211 Report post Posted January 5, 2017 Most things are possible. Do you intend to do it or are you going to pay someone to do it? Why the M70? thats a big engine, its also old and not very powerful, I don't see any reason why you would want to fit it to a GT86. Share this post Link to post Share on other sites
S18 RSG 429 Report post Posted January 5, 2017 The M70 has something like 300hp and probably weighs somewhere in the region of double the FA20. I admire your ambition, but consider your options before spending any money. You'd be making the cae significantly worse to drive (given that weight distribution and CoG would be shifted forward) just for 100hp and something unique. That's a lot of work and money for little reward. If you didn't care about power and just wanted a V12, a 1GZ-FE might be a better shout as it's a Toyota engine already. Makes around 300hp/350lbft and probably fairly cheap, but same downsides as mentioned already. Share this post Link to post Share on other sites

Sideways? 33 Report post Posted January 5, 2017 I admire the desire to be different, and fitting a V12 would definitely be different... I think the main problem you'll face with any engine swap is the length of the engine to include the extra cylinders, as a flat four the engine is only 2 cylinders "long" whereas a V12 would be 6 cylinders "long"... Plus as mentioned previously, that is a big heavy engine that isn't even very powerful... If you want to swap a V12 you want the newest one you can get your hands on, simply because it will be more compact, lightweight and more powerful...

nerdstrike 186 Report post Posted January 5, 2017 BMW's S85 V10? That M70 engine is 75 cm long, and the S85 is slightly longer still! Then add a big radiator, and you have the 7-series bonnet that hid it! Share this post Link to post Share on other sites

Yes, I know that's US eBay and no I've not read the articles to check they're even legit, I just saw them when I searched for the engine to find the weight this morning.
