Suzuki Samurai Engines

What are the drivers available that fit into a 88 Suzuki Samurai? My friends we are about to die and he loves the car ... So please do not say a new car. Is there anything other than a motor Tracker? Maybe something with a bit of speed and power. Any help would be great.
Thank you TJ

Here are two options. One is for an exchange of diesel and the other 4.3 Vortech GM. He probably won
t be cheap, but will give you a bad @ $ $ Sammy.

Wil a Nissan 1200 motor form and run like it was made for him, you can also try the 1998-2000 estimated or engine speed.
engine note - full use and Trani

If yours is two wheel dr's easy if it's four wheels not so easy to check one of the only jap engines pick ups and trans you should check in the salvage yard with tape, etc. blank meter to check something About 2 / 0 or if your axles will not deal more tourque or HP or part
