Yes Pete,
my most recent 25000 miles have been propelled by same [

]
Jon is right, they are a beautiful bit of engineering. He will know my Red SPS 2.5L
for the first 10000 miles, I would say it was just slightly tight, but after that it has become really really sweet.
he will advise you the correct Oils to use, and 6000 intervals etc. I have done all that and the engine is really nice.
the Hoffman chips are good, and the SPS BB turbo is too. At one time I thought the chips were running the engine rich, but he suggested I check the mixture setting on the AFM and that sorted it. Straight thru the mot on nominal emissions.
It uses Zero Oil. I am told this is due to the BB K26/8 Garrett hybrid turbo, as opposed to the plain bearing original KKK.
Other bits of spec you may be interested in are: 55lb injectors, 3" DP & Exhaust, Stg 1 I/C mod, Std AFM, Std T/Body, 2.5L, Forged OE Rods (from old 220 car), Cometic HG, Std inlet manifold (just - a LR Inlet was making me curious) std cam. The car is a great daily driver, 0-100 in 14.2s, boost showing from about 2000rpm. up to 28mpg in general use. Maybe 30 on an economy run if you had the patience. It rums 1.2 bar.
The engine is a bit of top class engineering which comes with an inspection report showing the dimensions of bores, parallelism, alignments, stuff a new car from Stuttgart would not even understand .... Briggs - Stratton, Live off the Heritage Engineering. For example the Perfect-bore Bore machining is done at working temp with a Deck Plate to simulate the Head being torqued in place for correct Bore alignment at operating temp.......
My car is not fast fast, but maybe a good daily driver compromise between a std 250 turbo and a 500hp 3.0 16v turbo with 4" pipe and 11" rears spinning at 80mph[8|]
Perfect-bore type companies are why the F1 industry is based in the UK. Highly recommended.
