1999 V70 Engine Swap - Comptability Question

[jdpowerski]

Hi folks,

I am in the midst of having my 1999 V70 engine replaced due to a timing belt tensioner problem that caused valve damage. My original engine was a B5254T (w/ low pressure turbo). The replacement engine which I have purchased and had shipped from a salvage yard (after providing them my VIN #) turns out to be a B5244T3. Please can you tell if this engine is a drop in replacement? I understand that Volvo changed the engine codes in late 1999 to meet an EC requirement that the displacement identified should properly match actual (e.g. B525 = 2.5L, whereas B524=2.4 liter, closer to the actual of 2435 cc). I'm concerned that this alternate engine may have other design changes which will make it not work properly/optimally in my car with all other original peripherals / computer, etc.

Does anyone have any experience with this? Please help.

Thanks,

JD
