My BMW V8 engine build thread

[zogs]

Lol, how could I be 100% sure how long my engine will last? Not to mention the variables involved with that (use/abuse, oil type, climate, the fact that my block already had 200k miles on it before the build, etc...). That's just a ridiculous thing to ask.

It's not a fully built race engine with wild cams and ITB's that needs tuned from scratch. It may need some tweaking to the maps to get ideal AFR's and ensure there's no knocking, but that is all well within the capabilities of the stock DME and fuel injection system.

no you misunderstand me, I am thinking if there wount be some detonation or something like that, what will burn pistons, or simply blow engine, becouse of m60 ecu and heads.

I am asking such a question, becouse one person, who has same hybrid, with vems, m5 intaka and so an, (he is drifter and mechanic) he says that without VEMS there can something go wrong.

Of course maybe he is wrong, therefore I want to ask some other people review who has this hybrid engine.

In internet there are planty of these projects and instructions how to build it, but NONE project is fully completed, with dyno tests and drived for example more than 2000km, so yes... therefore I am thinking to put stock m60b40 engine,and drive with no worries, or make hybrid, becouse I also have b44 engine.

Then you are for 100% sure that the engine resource will be long and nothing will happen? Maybe you know some person who has already derived some time with hybrid engine?

Other question, other block I have b44 banks, aren't there different pistons? Can I put on it b40 heads?

[zogs]

Well, I have no idea why you'd do that, but you can do whatever you want...

ou, that's not so good :D. yes there would not be a problem to run it, but I am worried about what will hapen for example after 2000km, becouse of the bigger copresion, smaller combustion chamber. I am thinking that maybe should put fuel pressure regulator and more productive pump, to give in more fuel.

No, I only got it running last week. I have about 200 miles on it.

My m60b44 runs perfectly fine on both a stock m60b40 chip and an aftermarket chip, both in the stock 404 DME. It idles great, gets the same gas mileage as my m60 did, and pulls hard to redline. I don't see any reason to go with a standalone system. If you want to get the most from the engine, you can get a custom tune made for the 404 DME.

and how much KM have you drived woth the hybrid engine?

ok thanks, you helped me alot, have you put your car on dyno with m60b44?

Yes.




It works well, when mapped pushes out around 320..330hp / 420..440Nm.

ou 320hp sounds good, what do you mean by mapped, you think chip tuning m60ecu?

[Jonsku]

so you say that it's for 100% safe to drive with m60b44, the engine will work perfectly and nothing will go wrong?

Yes.

Is some dyno tests with this engine, and some reviews from these engine owners

ok but how is with m60 managment on b44 block? Doesn,t b44 need more fuel than b40?

The MAF measures the increase in airflow, the DME adds fuel accordingly.

Major props on your build looks great!!!

On a side note it makes me happy that I went with an ls based swap in my car. The complexity of the m60/62 is crazy compared to my ls based v8. I literally rebuilt and assembled the entire motor in 2 days including having the crank ground and glazing the cylinders.
