socalsleeper Posted August 11, 2020 Share Posted August 11, 2020 Thanks man. I do have one question and you can save me a bunch of reading. Aside from being oversized (99.75mm versus the OE 99.5 bore) are these stock compression ratio for an LGT? I looked up the part number and the spec sheet says these are +22cc. Thanks.

NAL_LGT Posted August 12, 2020 Author Share Posted August 12, 2020 No worries. I believe it depends on which cylinder heads you intend to use, B25 that came on the 05 LGT or D25 in later models. For B25, the combustion chamber is 56CC and the compression ratio is 8.5:1 For D25, the combustion chamber is 50CC and the compression ratio is 9.1:1 Just in case I would recommend calling Mahle performance customer service, They are usually pretty good at responding to these kinds of questions. They answered mine when I called. Thanks man. I do have one question and you can save me a bunch of reading.

NAL_LGT Posted August 12, 2020 Author Share Posted August 12, 2020 Here is a link to the spec sheet http://www.us.mahle.com/media/usa/motorsports/wrx-2-5l-2020-web.pdf They are the second from the top. Link to comment Share on other sites More sharing options...
NAL_LGT Posted August 12, 2020 Author Share Posted August 12, 2020 Sorry for all the messages, I looked into it a bit more. Based on an assumed deck clearance of 0.3mm and gasket thickness of .6mm, and including the dish volume of 19.3cc, the compression ratios come out to the 8.5 and 9.1 with their respective combustion chamber volumes.

socalsleeper Posted August 17, 2020 Share Posted August 17, 2020 Thanks for the update. I am planning on contracting a machine shop today or tomorrow to get some measurements on my block. My only reservation is I’m considering an H6 swap. Link to comment Share on other sites More sharing options...

Tehnation Posted September 17, 2020 Share Posted September 17, 2020 any pics of the journals? why did you pull the motor apart, what was the failure? Link to comment Share on other sites More sharing options...
NAL_LGT Posted September 18, 2020 Author Share Posted September 18, 2020 I dont think I have any picture of the journals. But the block just came back from the machine shop. They cleaned and inspected the block, polished the crank shaft. They also checked the journal dimensions and they were all within spec for stock bearings. This engine I purchased from someone else a while back because it has less miles on it. I removed my original engine because of a head gasket failure. And since the engine was out, I figured I would upgrade. I believe this engine was removed because of a turbo failure. The previous owner was extra cautious and decided to replace the engine as well.
