How much trouble really depends on how much you know about cars and engines. If you know exactly what you're doing then it should go relatively well. If you are winging it, then remember, you are converting to an engine that is quite a bit bigger and things may not fit very well. If you don't know much about engines, I'd take it to a local garage or your local car guy to get it taken care of.
You'll need to either pull the engine or the transaxle. The engine would be far less trouble, but it will still be a bit of trouble.
It would be cheaper and easier to get a td engine and drop it in.
It stalls even when warm
Yes much trouble. The motor mounts are not the same as well as the axels. It would be easier for you to convert the 420a engine to a turbo modified. They make turbos kits for the 420a
Fixing the problem which causes it would be the first step.
Could be in need of a tune up.
just change the shocks buddy
No you would need to change out the whole engine. There are a lot of things a diesel engines has that gas engines don't. It is possible in theory, but in practice it would be so expensive a brand new gas engine would be cheaper.
It should theoretically be possible. However, it would be easier and probably cheaper just to replace the engine with one designed for gasoline.
A Sierra Beasley. That would be my best friend
its PROBABLY the engine or the batteries are almost drained
One cubic inch equals 0.016387064 liters, so a 305 cubic inch engine would convert to 4.998054541 liters, which would be referred to as a 5.0 liter engine.
