As i am crazy still toying with idea of buying the 72 tc project
car, (its fully disassembled in boxes) to build as a race car. Depending on class you could reasonably argue for use of either a Toyota or ford engine and sequential tranny are allo
wed. Engine rule is swaps are allowed as long as it is the same brand that the manufacturer has used...so thus the engine choices. It would take a little time to get the first log book but i think doable. After racing with a sequential i would dread going back to h pattern.
Theres a company in portugal that has hundreds of used sequential for sale all in the 3k range.
Interesting for the street the have a booster sequential with syncros not designed to withstand clutchless downshfting unless you add a autoblip, which requires a standalone ecu.
Weird side note- i recently saw a maual tranny set up for people with use of only 1 leg, much like an old vw sportomatic, it has a sensor on the shifterknob, when you press lightly on knob a motor operates the clutch.
At red lights you can put in nuetral or just depress shifter knob. It somehow sensed the timing of the clutch release and was quite smooth. Kit was made in india, was under a grand. The driver with the disability had it all done for free via a charity.
