i have an 88 rx7 and i want to drop a 20b cosmo twin turbo in it. how much work am i looking at to succeed at this? any help would be greatly appreciated

Are you asking how much work.... or how much $$$$$$$$$$$$$$$$$$$$.

Do you want a stock setup with stock turbos... or are you going to go single?

Do a search.... there are tons of threads on this... and bottom line.. it won't be cheap.

"More than you can afford pal, Ferrari."

Just get a piston engine, it'll be easier in the long run and less expensive.
