New member- v70 t5

[Bbeyer]

Hi, thanks for adding me to the forum!

 I have a 2001 T5 V70 wagon. I bought the car with a broken timing belt and crashed valves. Put a head on it and used it for about a year, and it started knocking at startup. The other day it just started knocking bad all the time. It's got 200k on it but the body is still nice.

 I'm pondering the idea of dropping  a motor into it, at the same time swapping to a five speed. 

 I'm a bmw guy and doing work like this is nothing new to me, but finding Volvo parts is new to me. I know where to go to find 24v swap parts for my e30 but I'm not that into Volvo's so I don't even know what platforms to look at for swap parts, etc. 

 Do I look for p2 platform v70 and s60 parts cars? Or will stuff from earlier cars work too? 

 Someone school me on these cars! Thanks

V70 and S60 cars will provide the engine. Do NOT go earlier than 2000 S70 for an engine. They changed it significantly in '99. Changed from hydraulic cams, added VVT on exhaust cam, valve stem diameter changed from 7 mm to 6 mm. Crank may have been lightened a bit in '99. You want an engine from a T5 car from S70 2000 or S60/V70 '01 to '04. Be aware that in '02, Voivo changed the rods on the engines. Same 90 mm crank stroke, but went from 139.5 mm length rods, to 147 mm length rods. Better rod length/stroke ratio. The thermostat housing changed in '02 or '03, and the new one is a total replacement, but your earlier model will bolt onto a later head. You want a B5234T3 engine. A B5244Tx or B5254Tx engine will be an LPT (low pressure turbo) while you have a HPT (high pressure turbo) engine. Difference is 81mm bore for your engine, 83mm for the other engines, but you have 8.5:1 compression, the LPT has 9.0:1 compression and you will have driveability problems if you put an LPT engine into your car and don't change your tune. If you buy an engine, the car it came from has to have a "53" in the 6th and 7th position on the VIN.

If you're coming from BMWs, you understand that the engine and the ECU have to play nice with each other for the car to run right. 2000 S70/V70 will be the only one to look at other than P2 S60s and V70s, and make sure that the engine is indeed a B5234T3, nothing else. It is stamped on the back of the engine, next to the exhaust manifold/turbocharger, to the left and behind the timing belt. VIN 53. wizzard_al gave you pretty much all the information you need!
