2000cc B5204T5 engine

[edifice]

Hi guys. Merry Christmas

Car is year 2007, S60-2.0T , code engine B5204T5. Power is 180bhp and 240nm. Original turbo is 12T.

Auto transmission is 5 speed, AW 55-51, without semi auto gear shift.

Quite difficult to get S60-T5 2.4 with K24 turbo. The only option is to get rid out of the 2.0T and do conversion, buy S60-T5 donor car (either from UK or Japan ) . But not that easy process, and this conversion job is costly

Now, what if i maintain the B5204T5.. 2000cc engine, upgrade the turbocharger, injectors, fuel pump and finally an ecu remap.?

Before we go further discussion, i need to know what are limitations of B5204T5 engine, how much bhp and torque this engine can handle within safe limit? (bhp and nm at engine/flywheel ) .

In my mind for 260 bhp and 320nm-340nm :

Blue injectors. 396cc . from S60-T5 2.4W

Walbro/DW/ Bosch fuel pump 200-225lph

TD04HL-16T with billet fins

3” downpipe

Remap


Thanks for any reply

Another option. B5254T3 which is the RNC version of the S60R/S70R B5254T4.
Green injectors. Borg-Warner K16 or K24 turbo. ECM software from a B5254T4.
Should putout 300+ Hp.

Applications: B5254T3

Volvo
2005–2008 Volvo S40 II badged as S40 T5
2005–2008 Volvo V50 badged as V50 T5
2007 Volvo C30 as C30 T5
2006–2007 Volvo C70 badged as C70 T5

Ford
2005–2011 Ford Focus badged as Focus ST
2007-2010 Ford Mondeo Mk4 badged as XR5 Turbo for the Australian market.
2007-2010 Ford S-Max
2011 Ford Focus badged as Focus RS 500
2009–2010 Ford Focus badged as Focus RS (345 bhp (257 kW; 350 PS) )

The engines as configured for the Ford Focus RS Mk. 2 and RS500 where not used in any Volvo model. They can be described as a RNC version of the S60R/V70R B5254T4 engine. Lower compression (different pistons), stronger connecting rods, same geometry Camshafts as B5254T4 but different (dual) VVT units. These engines use a bigger Borg-Warner K16 turbo instead of the K04, the K16 turbo is an integrated manifold turbocharger, it slightly outperforms the K24 used on the B5254T4 S60R/V70R engine.

You would need to remove the RNC front motor mount and bolt on a front motor mount from a RN engine. The RN mount bolt holes are still there on the RNC engine. You will need to use a intake manifold from a RNC engine. The intake bolt pattern is different. Exhaust bolt pattern is the same. There will be some hose and wiring re-routeing.

By going to a RNC engine you gain graphite coated pistons. Improved coolant circulation in the head. Internal cyclonic PCV.
