VolvoNor Posted January 13, 2015 Report Share Posted January 13, 2015 (edited) Hi everyone. Almost ready to get started on my rebuild and I've read through a lot of the RN threads on the forum. The transmission is a M66EA31 pulled from an '05 V70 AWD with a D5244T (around 150k miles) and the engine, a B5254T2, was pulled from an '05 S60 (70k miles). The plan is to (hopefully) land at around 400AWHP and I want to keep the 9.0:1 compression ratio as I really like the torque in the lower register on my current engine. I've started disassembly of the engine and I'm waiting for the cam lock tool to be able to continue. This will be a complete build with H-beams/pistons, new bearings/seals etc., NA intake and TB Haven't decided on turbo yet, but probably a garret of some kind(need advice). I'm looking for some info on the gear ratios of the EA31 as I don't have vida yet. Google left me with nothing. Advice on SM flywheel, clutch and PP would also be greatly appreciated. Edit: Found the info I needed in this thread: Ratios: M58L M66EA31 First: 3.38:1 3.750:1 Second: 1.90:1 1.905:1 Third: 1.19:1 1.194:1 Fourth: 0.87:1 0.838:1 Fifth: 0.70:1 0.652:1 Sixth: -------- 0.540:1 Reverse: 3.30:1 3.397:1 Rev. final -------- 4.941:1 Final: 4.00:1 4.00:1 I hope my english isn't too bad as it isn't my native tongue... Some pics: B5254T2 Compression test done by the JY, not sure if I'm to trust it...

VolvoNor Posted February 6, 2015 Author Report Share Posted February 6, 2015 (edited) Small update: Still waiting for most of the parts for the engine rebuild, but I got a new coilover kit today. KW V2's Currently running FWD due to a broken prop shaft. The VC and rear diff is is also going to be replaced. I've also ordered front and rear swaybars with adjustable endlinks.

Commander Riker Posted February 6, 2015 Report Share Posted February 6, 2015 Cool. I'm running a similar setup and like it quite a bit. Post lots of pictures. We like pictures. Quote Link to comment Share on other sites More sharing options...
NEU Posted February 6, 2015 Report Share Posted February 6, 2015 More info on the AWD KW coilovers... Any shots of the rears? Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted February 6, 2015 Report Share Posted February 6, 2015 Since that trans has the S60/V70 style shift mechanism, you will need use either the 98-00 shifter & cables & mod the shifter cable attachment at the trans, or use a S/V70 shifter and make an adaptor plate to fit it to your tunnel base, at the correct height to clear your console (low). You went with the diesel trans for more bottom end pull I presume? Quote Link to comment Share on other sites More sharing options...
VolvoNor Posted February 6, 2015 Author Report Share Posted February 6, 2015 (edited) Pics for NEU: The kit is a INOX Variant 2 Coilover kit (KW part number 15267004), it is height and rebound adjustable Hussein: That's the exact reason I got it, that and better mileage. I drive about 1000 miles per month. My car is a manual already, so I thought the easiest way would be to modify the cable attachment/fork.

Big Will Posted February 10, 2015 Report Share Posted February 10, 2015 Nice project you've got going. I love to see more people building the 9.0:1 compression motors 1 Quote Link to comment Share on other sites More sharing options...
