OK, this is an 81 Model Handivan with the suspension, 3800l buick v6 engine, borg warner t5 gearbox and diff from a 89 model V6 VN Commodore

The engine stock trim, it should get around 0 - 60 mph in around 2.8 secs

With the engine up to formula holden specs, at 450kw it would do around 2.2 secs

With twin turbos and over 800kw, it should be able to hit around 1.7 secs

This will all come down to getting all the power down. And if I get it down, stop it flipping over.

It's a fun little experiment.
