Gents,

What is the going rate for a 3.8 complete engine in the UK?

Will it fit directly into the 3.6 engine bay?

What electical mods are necessary?

Should I just buy a 3.8?

Sean.
What exactly are you seeking to achieve / experience ?

You will need more than just the engine assembly if you intend to
fit into E34 //M5 3.6 vehicle.

Try a main front engine harness & DME for starters, MAF etc.

Then, exhaust manifold & wire knit metal matrix cats as std on 3.8.
(3.6 cats can be used but are more restrictive but light off quicker)

I would buy a 3.8 vehicle if thats your ultimate aim.

i would think the added complexity would come from the 3.8's ignition system and it's DME. If you run the 3.6 distributor and keep the 3.6 dme, a remap should get things sorted, imho. Perhaps i'm oversimplifying.

In the US, dinan among other tuners did "stroker" engines, resulting in 3.8 - 3.9 Litre capacity, often using the 3.8's larger throttle bodies and exhaust system.

Seriously. Have located 3.8 engine on Ebay in Redruth.
"Caveat Emptor";)

A side, there are integration issues unless you run a stand alone aftermarket
engine management system.

The B36 Bosch DME supports a default check of the intake system @ keyon.
The functionality of the intake step points for both vehicles is not the same.

The B38 cal also turns the flap at an additional point in the rpm range.

I believe a B36 eprom & DME will not run a B38 & maintain full functionality
There are additional calibration values within the B38 DME @ 2,300 rpm not
supported by the older 3.6 Bosch DME.

Good luck.

Unfortunately its another one with 100k on it that my bro is trying to ruin!
Currently working on a good friend of mine to buy the whole car and restore and cherish it like I know he would.Wish me luck!
