Guys
More of a technical question, can anyone tell me which BMW v12 would be best suited to a little tuning.
5.0 or 5.4 V12 from e38 this is for a project im mid way through, however i do require a little more than 300hp, or 326 of the 5.4.
Im aiming for a better figure of 450 - 500hp. Also any specialists that could be recommended would be great - London Area.
Thanks

what type of tuning? for that kind of power the only way is boosting unless you go for a 850CSi engine that is probably really expensive and not that easy to get 20% more power out of it, but if you have enough money...and if you are going to boost engine you can go with E32 5.0 it doesn't matter much
What costs are we talking?
N/a is the preferred method due to the application, however im being nudged toward supercharging, which may not be a massive issue in the end, again i guess the same applies, what costs and hp are realistic from forced induction. on say either the 5.0 or 5.4 engines.

Forced induction it is then The 5.0 will comfortably go to 500bhp and the 5.6 will go to 700 bhp turbocharged but noone has sucessfully blown the M73 5.4 yet.
NA tuning is hopeless and there are very few options for either the M70 or S70 and nothing for the M73.
Both the M70 and S70 will bore to 6.0 at a price but dont expect a lot more power, just an increase in torque.
The head design on all the V12's are very poor and thats the limiting factor when going NA.

fascinating to see what they add/upgrade though to achieve that sort of power.Interesting thread this.
I had a simple Ls3 in my last project gave great power at 530hp for £6,000 ish. to think they want those prices for tuning is scary. Good old blower will do just fine!!!!
Im sure there is lots to be impressed about but at those costs its not for me, or my bank balance.

It's unusual, It wouldn't surprise me if there was only one engine, and that was the different stages it went though, and it is still sitting in their workshop.
The BMW v12 was never planned for big bhps, it's a fun and interesting engineering project to fit one, but certainly not worth it for making power.
Alpina had the B12 5.7, based on the CSi engine, with 416bhp, but you could get an M5 V8 to do that far easier.
If you absolutely, positively, need a V12 with plenty of power, the smartest move would be find an AMG V12 BiTurbo

670bhp for their highest rated production engine, and the usual 604bhp version look to be remapable to 690bhp.

just pm'd him, hes not got his project started yet. Leaving the engine issue for a later date.
Ill keep you all abreast of my progress, no re post im afraid, must be two mugs ready to part with a lot of cash. Got transmissions to consider next, i have a nice hewland 6 speed transmission here brought cheap from a friend so i have lots to consider, im just toying with different ideas, to keep things interested. i like the cheapness of the initial purchase of the bmw v12. but it seems that the overall cost may exceed the v8 options. onwards and upwards. Thanks for the input guys.
