Are you intending to swap 2.5 parts on to your 2.2 or are you getting a 2.5 block? Is it a pre or post 89 engine. No TBI’s never came as turbo cars. If it had a turbo it got 4 injectors on the intake runners. And finally why would you want to lose 42 horsepower? (presuming everything is stock)

Much is possible but you need to give accurate details.

2.2 Engine in place of a 2.5?? Or 2.5 in place if a 2.2??

What year Turbo Engine in place of what year TBI?

What year TBI in place of what year Turbo?

Accurate answers need accurate details.

Half ass answers, not so much.

Your choice!!

Thanks
Randy

Hi. Sorry about the left out info. Bought a 1986 New Yorker with a 2.2 Turbo 1 but the head gasket is blown and the engine was run out of oil rod knock on cylinders 1 and 2. Got an 1986 2.5 tbi with low miles and need to know what is needed to make it run correctly in place of the 2.2 turbo 1. Can the turbo 1 setup fit the 2.5. Any info helps thanks.

It's a go but with some cautions.

The 1986 2.5 TBI is a bit of an oddball Engine with it's taller deck.

This means it takes a specefic 1986 or 1987 only timing belt.

Oil pans and a few other Engine parts are not interchangeable.

The connecting rods are a light weight design so don't abuse them.

It physically bolts in place fine but the cyl head is almost 1/2" higher.

This means there will be a bit of massaging to get the exhaust on.

The intake and exhaust manifold with turbo bolt on the cyl head fine.

The intake/exhaust manifold bolts/studs need to swap over as well.

You need to use the Turbo distributor and New Yorker wiring etc.

There are no 1986 2.5 Turbo computers so you have 2 choices.

Run the original with +20 injectors to make up for the larger Engine.

Or you could try to get a custom calibration using the stock injectors.

A word of caution, Turbo Engines run lower a compression ratio!!

This is a safety measure to ward off harmful piston cracking detonation.

Many have run TBI Engines but they proceed cautiously when doing so.

Premium fuel is highly recommended with a Turbo, more so with a TBI swap.

Excessive heat in the combustion chamber is the enemy of Turbo Engines!!

Detonation kills all Turbo Engines so always keep this in mind.

There's more to add but this might give you a starting point.

Please keep any questions simple and on point.

Were happy to help whenever possible!!

Thanks
Randy
