I purchased my first Opel Gt this last weekend!!! I was able to get a rust free (minus battery tray) car that had just had the engine and all go items removed about a month ago. She (Bobbi) needs an engine, trans, exhaust and such along with interior. This car is to be built for myself to enjoy and then turned over to my son once he is 16...I have 9 years for the project. I am heavily leaning toward a 13B rotary or Renesis. I can pick up either for about 2k here in SoCal for engine and transmission and even sometimes a whole parting out car. I have looked at some of the RX7 threads and like what I see, but no-one has really tackled a Renesis and I worry that the 6 speed manual transmission is too short. I am open to other alternatives, but really want to stay around 2-3K for engine and transmission as I need to still spend money on cage/interior/rear end/paint. I want about 150-250 hp to have fun, but not die. Thanks so much for comments.
