I'm hoping way less than 6 year! Engine is at the machine shop getting line honed. I ordered all my titanium for my exhaust 2 days ago and the eletric a/c compressor. I still have to buy probably 30-40k of stuff yet like paddle shift steering wheel and engine management system that will work with my trans for shifting. And shocks and springs then I have 90% of the rest of the stuff I think.
