mine is putting out 243 at 7500 and 191 ft lb at 5500 It poos over a L20B
stock block and head, steel internals, slight mods to a billet cam, 9 you cant get the lift and duration from grinding a stock cam) the head is so close to a L series FIA head from a porting perspective it is not funny.
my thing passes Shelby Mustangs, De Tomaso Panteras, Porsche 2.7 RS & 3.0 Carreras, and 260z's all in race spec, at Phillip Island 2011, in 2010 I was in the pre 1970's class with mistangs, Corvette 7 litre, Morgan v8s, and won all four races.
At bathurst, best was a fifth o/r behind four porsches in 2010
This Datusun 2000, is acknowledged as the worlds longest racing, most succesfull, and most winning Datsun Sports 2000, currently today. it is quick, it uses all parts available in the day from the Nissan competition parts catalogues, it isnt a highly modified all out thing, just a basic close to stock Datsun Sports 2000, just well built and well looked after.
My other THING, is a FJ24 equipped Datsun 120Y factory built rally car, for a little sheep farmer in Talmalmo, back in the 1980's, IT is developing 320hp at 8500, on twin side draft carbies, all atmo, and all standard as it came from Nissan, save for fresh steel and new internals
It's off to the Alpine rally in a couple of weeks time!
Thank you for the insight into your beasts!
Im glad to hear of peeps like yourself who are in the rarity still embarrass so many in nose up in the air machinery and way bigger capacity.
In your experience has anyone ever stroked a u20 using the 93mm H25 crank?
Im sure it wouldnt make more power but I wonder about the torque.
Also your U20 engine using carbs, roller rockers, aftermarket rods and other top notch
equipment or mainly factory prepped internals? In your view is there more available
from a U20 engine using latest injection, titanium valves, rods and other bits etc?
Ive seen what some of the porsches run in terms of dollars and Im sure by the sounds
of many using the U20 its seems to way less in costs to get it competitive.
