Oh here's some other Tri Y arrangements just for interest:

1979 6.9 #5541 (Red Bull)
1978 6.9 #4248 (Skye)
1979 6.9 #3686 (Moby Dick)
1978 6.9 #1776 (Dora)
1977 450SEL #7010 white -P
1975 450SEL #8414 gold -P

Obviously on some cars clearance is an issue:

1979 6.9 #5541 (Red Bull)
1978 6.9 #4248 (Skye)
1979 6.9 #3686 (Moby Dick)
1978 6.9 #1776 (Dora)
1977 450SEL #7010 white -P
1975 450SEL #8414 gold -P

something like that would be really nice ,,,


But,there is no space for that..
Even with current desing it has to clear:
*brake system (lhd version)
*power steering (lhd version)
*Ht leads and leave enough space for servicing (plugs)

To fit crossover pipe:
*radiator needs to be modified
*radiator position has to changed
*oil cooler has to be relocated
*cooling fan has to changed to electical one

to fit 4 inch downpipe from turbo:
*body needs be modified (make a "tunnel" inwards  under passenger footspace)

And then i need to figure out how fit cooler  ;D

So we are not talking about exessive amounts of space here

Might be a dumb question, but how do you plan on keeping heat in the engine bay manageable?  6.9 tends to run pretty hot as it is (normal for them), I am guessing you will need huge intercooler as well as increased fan air to keep things under control?

Cooling fan is going t o be 4000 cfm 16 inch unit,intercooler size and shape will be decided after the radiator and cooling system is ready

Good one  ;D


Now i got injectors for this engine as well



floyd111

Can those fuel injectors be used on any gasoline W116? (Like my 280SE)
If so, can you share where you got them and at what price?
I am just shopping for 6 of them..

s class

Those injectors can be used on a 280, but you will need to do the following :

a) ream the injector ports in the head to accept them
b) fabricate a fuel rail with pressure regulator assembly
c) install an aftermarket injection management system to run the injectors.
