People talk about engine conversions like they're a single decision. Pull the old one out. Drop the new one in. Better power, better torque, done.
That's not how it works. That's never how it works.
In this episode AJ breaks down why an engine swap is the most cascading modification you can make to a vehicle. Change the engine and you've potentially changed the emissions profile, the cooling requirements, the driveline loads, the braking requirements, and the ADR compliance status — all at once. Every one of those is a compliance question in its own right.
Plus — What Would AJ Do with a bloke who's halfway through a diesel conversion and has just realised nobody sorted the compliance pathway before the engine came out. And an Ask Willy Mailbag conversation about a V8 petrol swap that everyone thought was straightforward until the braking question came up.
The engine swap itself is the easy part. The system around it is what determines whether you can drive it legally when you're done.

What is Built Right with AJ?
A show about doing it right the first time. AJ Elgayar — engineer, mechanic, sixteen years Army veteran — covers vehicle builds, modifications, and the engineering thinking that gets a project across the line properly. Cars, four wheel drives, touring rigs, tradie utes — the principles don't change.
