Hi, I've been poking around here for a few days, great site. I have a '98 V70 2.4L turbo with a bad engine, I have a line on a good 2.4L non-turbo from another '98 V70. I'm wondering if the good engine will accept all of the turbo parts and bolt into my car without issue? Probably a good idea to change the timing belt and oil pan gasket while it's out of the car too, right? Anything else to look out for in the swap? Haveing not seen a non-turbo, what really are the differences in engines?

Thanks for you help!

 

I'm not sure if anyone has written to you yet but I wanted to tell you to STOP before you go any further. Non Turbo engines and Turbo engines are not the same. First big thing is the compression ratio. Turbo engines have about an 8-1 compression ratio while normally aspirated engines have about 10 or 11 to 1 ratio. In other words, Turbos add alot of extra forces to the combustion chamber and if the compression is too high, you are going to blow head gasket after head gasket. Beyond that there are other related issues with wiring, enrichment systems, waste gate controls, transmission-manifold sensors .... the list goes on.

Anyway, buy a turbo engine.

 

1. Welcome to the forum. Thank you for joining.

2. To answer your question simply yes you can turbo that N/A engine. However...

3. The engines might look the same and for the most part are the same. They aren't the same and it will take a lot to turbo it. Yes I know confusing.

Now you have a head start by already having a turbo engine with the parts, so the cost issue is greatly decreased already. But... It isn't just as simple as bolting the turbo parts to the N/A engine.

If you do all the work yourself your going to safe a lot of money. If you have someone do it expect to pay a good amount of cash.

1. The cams are different.
2. The compression is different.
3. Etc...

Your still looking at a custom ECU tune to get it all right and work properly. And this is very important and will cost you good money to get it done right.

Personally just buy another turbo engine or get the one you have overhauled and fixed. Even though you have all the turbo parts already I still feel your going to be spening a lot of money on this project when you could just save yourself and your money by buying another turbo engine.
