SO vs SU depends on the engine.
9.3.2. Engine Swapping
9.3.2.1. Cars that do not have an original type engine, (e.g. the engine was not available in the model, chassis and year of the car), shall be classed based upon the vehicle for which the engine was original.
9.3.2.2. The car shall meet the weight minimum of the chassis, model and year for which the engine was originally available in the chassis of a US model, (e.g. it will assume the characteristics of the donor car).
9.3.2.2.1. Location and maximum ballast weight allowed is specified in 9.3.13.
9.3.2.3. Swapping or mixing of engine components between different engine types is not permitted, (i.e. mating the head from a M40 engine with the block from a M10).
Things like bumpers, though, must stay original to the year of car.
cheers,

I looked into converting the car over for SO, but because the car is an ES it will always be SU - even if I put IS components in it…unless I’m reading the rules wrong. Aside from that it will probably be a while before I run competitively - this is a learning car
In the meantime I’m having fun building it![/quote]
