Yep. Impossible, I'm afraid. Though I won't be unhappy if my 2.0 litre conversion drops 10-20bhp.It's hard to go back though.
The Toybaru IS underpowered though. There's no denying it and no amount of skinny low rolling resistance tyres will disguise that for more than an hour.It's a similar situation with the car market as a whole, they were more fun with less power and actual connections to the engine and chassis, but if anyone made something like that now everyone would complain that it's underpowered and unrefined.
