  • V70 T 5 engine replacement

    Hello V 70 fans,

    I have a 2002 V70 T5 that the engine packed it at 321,000 miles. Mechanics think it has a couple of burnt valves, still running, just on 4 cylinders.

    I found a 2001 engine that is supposed to work but... my 02 is either a 2.3 or 2.4 and the 01 engine is the reverse of what I have. I'm not sure which engine I have.

    Question: If I have the 2.3 and the replacement engine is the 2.4, can I still use it? I'm doing a full repower from the front belt to the end of the transmission including the turbo.

    I am looking for guidance from knowledgeable Volvo owners to advise me.

    If I can get this car to 500,000 miles, its worth the investment to me. Looking forward to hearing your thoughts.

    Anacortes, WA

    I don't have much experience with this, however you will have to use all your externals off your engine to get it to play with with your computer and wiring. So what long block can you use? Since everything bolts up between the 2.3 and 2.4 you have only to make sure the compression ratio is 8.5 since the 2.4 was made both high compression for natural aspirated and 8,5 for turbo.. all 2.3 are the same so its safe for any turbo application except if you have a low pressure 2.4 , installing that on a 2.3 will make it very slow. also you cannot install a low-pressure 2.4 into a high pressure 2,3 or 2,4 system. It will predetonate. so you must find out what you have. look up wiki Volvo modular engines and check that against your data plate.
