Thank you for the feedback. I spoke directly to the US distributor for the HKS engine and parts . . . and he assured me that the very large company is very reputable and has committed to provided parts for at least 10 years . . . and combined with the reputation of this engine . . . it gives me comfort to go ahead with the HKS. The companies "mainstay" are high quality engines for race cars.
I am building a CGS Hawk Arrow II - 2 place being built.
