$40,000
I hope that includes the original cost of the car itself!! (approx. $15K in mods + $25K for the car)...
The thing about heavily modding out a car is that you'll never ever, ever get your money back on it.
It comes down to this: To make an all wheel drive turbo Lude you better (1) have cash coming out of your azz and (2) REALLY LOVE your Prelude
If, on the other hand, all you want is
any awd turbo car, take your loss, sell the Lude, the parts and get a WRX or something comparable.
It sounds to me like you want a WRX etc. deep down. Don't waste HUGE money trying to make the Lude something it's not.
It's your call, but if you do it, I give you props!
