John assured me these components will be good for up to 7.5k RPM.ĭom suggested ceramic coating the pistons, the same as used on the Power’s pro stock bike and then the Power’s black edition 5.0 Speed Six engine. Looking at the components on the market I felt that the JE items were very good quality and represented good value for money. I also looked at re-machined Chevy H beam rods which were great value but a fair bit heavier than the JE items. I did look other combinations of rods and pistons including Diamond forged pistons, Arrow and Carillo rods which were all considerably more expensive.

Lightweight in theory will keep the engine as free revving as possible which is often lost with high capacity RV8 engines. I spoke to John Eales regarding my requirements for the engine and he recommended his own 6 inch I beam forged rods with inconel bolts with Omega 96mm forged pistons to match. My objective for the pistons and rods was to build a robust and lightweight bottom end within a sensible pricepoint. Dom was happy for me to source the components from John Eales for the build. This crankshaft was the used in the engine build.Īfter speaking with Dom at Powers Performance regarding 96mm pistons and con rods to match the crankshaft he was able to commission custom made items but this did not make much sense knowing that John Eales has variety of tried and tested upgraded Rover V8 components in stock. These crankshafts are very hard to come by now as there have not been any unmachined castings available since production of the Rover V8 ceased in 2006 and stock rapidly diminishing. These long stroke crankshafts are based on the unmachined 4.6 crankshaft castings and were machined by Doug Kiddle to suit customers requirements. Powers Performance have a machine shop onsite therefore this work was completed in house by Dom.Ī couple of years ago an opportunity arose to purchase a Doug Kiddie 91.5mm stoke cross drilled crankshaft. The block was bored out bored out to 96mm and fitted with Top Hat Liners. Throttle bodes test fitted to the car before engine removal JE low profile inlet manifolds fitted to a test engine JE low profile downdraft inlet manifolds vs JE standard downdraft inlet manifolds

I purchased the full kit including, manifold, ITBs, filters, injectors, fuel rails from John Eales. After measuring and chatting to John he came up with a solution using a low profile multi-throttle inlet manifold which would leave enough room for the filters while still providing room above for breathing. John Eales sells both downdraft and crossover Jenvey throttle body systems. The car is still primarily a road car and I would like to retain a standard look. I have seen the crossover system fitted but never a downdraft without a cutout in the bonnet to allow the ITG filters to protrude through. The first challenge… getting a Jenvey downdraft ITB kit to fit under the bonnet of a TVR Griffith. Jody at Python Racing will be completing all the work which falls outside of the engine rebuild and ECU as there is quite a bit of work required converting to throttle bodies and the various “while the engine is out’ jobs. Powers Performance (then TVR Power) was the original engine builder for factory therefore the original engine in the car would have been built in the same workshop. I have an existing relationship with Dom, I trust him to do a good job and he is the only one I spoke to who would entertain offering a 5 year warranty on the build. The rationale behind specification is explained in the previous blog post – Īfter speaking with a number of suppliers I decided to use Dom Trickett of Power’s Performance for the engine build.
