Sorry to hear that meu irmao... hope you get it sorted soon.

What is it with M5s in Brazil - all the times I have been over there I dont once remember ever seeing any 5 series, never mind an M5!

yes , e34s are not that common here , but we got two at home , an e34 530 and the beast...

i am undecided about this port & polish stuff... i don´t want to ruin the lower end torque... but i~ll sort it out as soon as i research and decide....

have anyone done this ? Port & polish s38b38 head ?

WE are back on the road !!

At the end we could not find out why only one valve broke. it could be that this one valve got stuck open for some reason but we could not find any timming issues. maybe some debris in the oil could have entered somewhere the valve steam and caused it to be stuck open ?

Well , we took the time to rebuild it to give more power. We reworked the cylinder head for more airflow , went with bigger valves for intake and exhaust, upgraded valve springs, larger pistons with higher CR for ethanol use, got everything new ( seals, gaskets, water pump, hoses, ARP bolts , vacuum hoses, sensors, fuel pump, fuel hoses, fuel pressure regulator, etc etc etc... )

we did the engine run in , and now we are going for a TD event this weekend.
After that we'll have a new live remap and dyno run...

here are some pics :

`yes, this weekend, 3 e34 M5 o the track in Brazil, this is priceless

Pad,

e34 M5s are uncommon anywhere in the world. I've never seen one in Europe, and I go there rather frequently. Imagine Brazil...
Excluding my own, I know of another 05 of them down (in good condition) here.

Not that many of them came to Brazil (like 50), and their owners in the beginning suffered from the e36 M3 curse (couldn't help avoiding the guard rails and such), so there shouldn't be many left.

e39 M5s, I know that a good 100 of them came over, and e60s, well over that.

What impressed me was the number of MBs SLS shipped and sold here already: 70 (!!) But then again, their price/performance ratio is probably one of the best in the supercar category.

Cheers,
Pedro
