Thats what i was when i went up to pick up my engine last friday. I knew Ian (who builds all the R-developments engines) could build a nice engine but he outdid himself this time! My engine was designed to make the best out of my gearbox, so we needed to lower the inertia weight of the engine. Thats why we set out to choose all components carefully.

The Cylinder head has been build completely keeping in mind we want a safe 9500 RPM rev limit. We reacon it could take some more but we are limited with the Sadev ST 75-14 figures. The specifications of the head are:

• “Trojan spec” biryllium copper valve guides
• Lightweight valves
• R-developments Springs and retainers
• R-developments prototype camshafts

The engine is also completely build, we went all out and made sure that the weight was as low as possible. Thats why we installed a custom made R-developments spec crank (note the fewer counterweights) thats much lighter then the standard one making the engine more rev happy. Furthermore lightweight Cosworth Rods are installed and the R-developments Cosworth 90mm 12.5:1 pistons including darton liners. The specifications of the bottom end are:

• Darton liners in the engine
• R-developments lightweight 86mm stroke crank
• Cosworth 90mm 12,5:1 ratio pistons (custom R-developments spec)
• Cosworth lightweight rods (custom R-developments spec)
• Cosworth bearings

Everything has been put together after being fully balanced, As you can see in the pictures below a prototype lightweight flywheel and Helix motorsport clutch have been fitted. I seriously can’t wait to put this baby in my car and rev the boll#cks out of it! There are a few minor things left though, source an appropriate dry sump system for FWD use and sort the intake (we are working on K-developments ITB’s at the moment). One thing is for sure, the engine is going to be amazing i can’t wait to crank it over the first time!!!!
