Do you have the years the TS cup cars were campaigned?
Looks like they used GX heads for the porting or some
rare cast with solid port roof, like feral had.

btw, Feral and I saw eye to eye on horsepower potential of the A series. eg: Quote: feral wrote: Just to throw some cold water on this hot topic, Quote: A14 Nissan engine with A15 crank bored to 78 mm (1568cc) Forged Pistons, Nitrated crank, Race prepped rods ARP Rod bolts, Full engine balance, Nismo lifters, Nismo high volume oil pump, 82 Degree cam, High ported head with Nismo valve springs and stainless steel valves, Steel light weight flywheel with Nismo clutch p/plate and solid centre button clutch, hand made interference sand bent headers, Wolf3D Engine management system with twin DCOE 45mm throttle bodies and HEI Ignition.

Steve Newings 1200 coupe race car ad As an outright contender this car was "NATIONAL" champion - (thats all under 2 litre sports sedans in OZ) against 2 litre cosworth engines and buckets of SR20 powered vehicles of all descriptions. This car with its 165HP @ 7500 rpm and 118 Ft lbs at 5800 RPM managed to wipe them on most circuits even the fast Phillip island circuit occasionally. It must be his horses were Clydesdales and a lot of the quotes being bandied around here are miniature shetland ponies This engine made 105 bhp per litre. A very good (In fact race winning) figure for a two valver.
