Just another E39 M5 LS swap, but with 2 snails...

I figured I might as well get this thread rolling.

Disclaimer: This is a PROJECT CAR. I am in no rush, so please don't post complaints about how long it is taking me to do this. LOL. I am a busy guy, and have a family, so this project is not the center of my world.

When I sold my other M5, my plans were to buy an M4 or a 911TT, but Clemster called me and told me about this car and made me an offer I couldn't refuse. I've always loved the M5, but I wanted 700+hp. Instead of spending $30k on an S62 engine, I spent $175 on an LS.

Thanks to Clemster, rao, Herrubermensch, and all of my other friends who have helped me out with this.....

Stats:
2003 BMW M5
5.3L iron block LS - brand new stock internal rebuild from the ground up
799 heads - fresh valve job and all BTR goodies here too.
BTR twin turbo cam
T56 transmission
Twin 68mm turbos (CX Racing, aka, cheap turbos)
Tial MVR 44mm wastegates
Tial Q BOV's
I will run a meth system of some kind

Shooting for 700-800hp at the wheels.

The M5 - Sterling Gray, Executive Caramel Leather interior. (Thanks to Clemster for the hook up)






The egine: 5.3L LS from a 2005 Tahoe.


The foam LS block for fitting..... It is an exact replica of an LS engine, with heads, bolt holes, the whole thing. Pretty sweet.


I used an i6 subframe, so I had to source some additional parts.....




I moved the cross support forwards about an inch to clear the oil pan.


Other parts

68mm liquid and oil cooled turbo


Tial Wastegate


The awesome Ford Taurus fan:



I will be updating this thread as the project goes along. I have a lot of pictures. So this will take some time.....

After all is done.
RK and Tim should do a 1/4m.
Can't wait to see the outcome on this build.

The engine rebuild.....

rao came to TF 2016 a few days early and guided me in the rebuild of the engine. Lunker325 was there with some help as well.











Rough looking lifter




Crank and block looked really good....
















New pistons, rods, and rings gapped to boost settings as per LS1tech




Chinese head studs

Since I'm trying to put a twin turbo LS in to an M5, finding an exhaust manifold is almost impossible. rao and I attempted several sets without any luck. Making my own set won't be the most efficient, but I don't really have a choice.

Very cool Tim! I'm glad to see that you've been able to make forward progress with the build - work and family can make it difficult to find time for projects. What boost are you expecting to be running to hit 700whp? What size are the turbos?

68mm

I'm guessing 14 - 18psi, from reading LS1Tech.com

I'll only run as much as it takes, I'm going to run conservatively. If I don't hit 700hp, then I don't. With stock internals, I don't want to go crazy. But from what I've read and what I've been told, I am following the formula to make my power goals. This engine is only meant to last me until I build up a forged 6.0L iron block to put the boost to. I just wanted to iron it out with this relatively cheap engine.
