History this swap really started when Z4 has changed a workshop to Cybul Radical Solutions (after almost 1,5 year modification in other workshop !).
My BMW Z4 has motor as standard type R6 3.0, and the engine compartment is not designed to accommodate such a large block
Already it has caused a series of complications.
CRS workshop made exceptionally strong, customowe foot steel motor S355JH ...
As a result, for serial production BMW engine cushion under the hood there was no place. Moreover, their strength was questionable, were not designed for such use and so extreme high torque. The workshop decided to replace them more durable solution.
Instead of serial components , were used for the hardness of polyurethane sleeves 85ShA used in sports suspension systems.
The serial space fixings pillows did not allow for the installation of manifolds - meant the need for a more labor-intensive solutions - this element also made from scratch.
The steering column on the section bulkhead-Mangler is also 100% a custom item. With this modification Mangler has been in serial site, which is key to driving the car.
This procedure was performed in such a manner that in no way impair the legendary precision driving this car.
The challenge also proved to be correct and safe routing exhaust manifolds.
Left collector require the implementation from zero so that not only able to fit in the chamber but also to maintain the throughput and capacity.
Right collector was quite heavily modified too.
The rest of the exhaust is also of the highest quality components - thin-walled stainless steel pipes x pipe system, culminating in dual mufflers Meisterschaft, made on special order for this project.
S65B40 engine is significantly higher unit of serial M54, who was installed. When the engine is already found in the body Z4 , it was necessary to modify the motorhead Z4 (to up to 6 cm in central place ! ) The aluminum engine hood was modified and equipped with customowe increase in allowing the engine to fit. At the end of the whole sanded and varnished so that the mask looked at the item factory
All this work took 1,5 year.
The next step , also 1,5 year ,was the all electric and computer modifications (f.ex- prepared the new computer EcuMaster from V8 engine to start it and to be able to connect with the other original components Z4 etc, ect. I cannot explain precisely the rest of those modifications
Finish=realization interior design in Carlex Design company.
