Sounds like you have the right skill set!
Welcome.
I get the Sevenesque cars but jeez they are ugly things.
Now you are talking though, moving up through a 240Z to a,Stratos. A thing of beauty!
There are quite a few Toyota powered cars appearing now from LB, but I don't have any experience of them. Someone will be along with more knowledge.
The impression I get is that they are more expensive to build although probably no more so if you measure it on "bang per buck", than an Alfa engined car.
