Can anybody help me?

And finally



Now, I have a lot of work with hoses and wiring

Clean car and a euro motor, looks like a properly done swap. :)

Plain US M50 is about the same in wiring wise to a Euro S50B30 :)

As you shouldn´t have any EWS stuff to worry about.

Thanks, but the problem was these pins of S50 engine:

4, 5, 6, 7, 8, 14, 20, 24.

I have no idea of electricity :(

that is an amazing way to do the swap...i didnt see a lift how did you do that?

for the pins, find the ETM, if its a searchable pdf (as in not a scanned copy) i could give you a hand.

Nice work. Now, the toughest part is to install the intake box. What booster/MC do you intend to install?

[Mike B.]

The intake is easy... It's the booster issue that's a bitch!

[Massive Lee]

Exactly. The interference between the intake and the booster. Go with e23 hydraulic system, or boosterless with Motomotion's twin masters kit... If anybody has a third solution, let's hear from it.

This pdf isn't a good manual?

You'll need the ETM for the real S50 motor, not the US M50B30. Most North american conversions are done with the M50B30 motor.

BTW I know how you installed the engine. You raised the front end of the car (black straps tied to the bumper shocks), and slid the engine underneath (wood crate/pallet). Right? Nice work.

:nice:
