Does anyone know if a sr20det motor will fit in my 2000 Infiniti G20t and if it will or won't, what tips do you give me to getting my car turbocharged?
Do some more research. With a newer car (p11) it's most likely going to be a lot easier to add a bolt on kit rather than a whole new motor. With the newer car your current engine should still be running strong and shouldn't have too many miles on it either.
Something like a modified Hotshot or F-max kit would be your easiest option. Or you could put together a custom kit, but that would require a little more knowledge, and depending on your wants it may not be any cheaper and it's definitely more work.
