I recently picked up a 97 Legacy GT sedan to use as my work car. I purchased the car knowing the transmission was in bad shape and would need a rebuild or replacement. I removed the transmission this week and had plans to swap in a 98 Outback transmission. I inspected the ring and pinion on both and determined the transmission in the GT which the PO advised was a low mileage JDM swap had a 4.111 ratio. The Outback transmission had the correct 4.444 ratio that should be in all of the 4eat 97-98 2.5 powered cars. I have searched the forums and not been able to find decoding information for rear axle ratios. I was only able to find a small sticker on the back of the rear differential housing with "T2" on it. does this indicate the gear ratio? If so, what is the ratio? My theory is the PO swapped out the original transmission with a transmission with the wrong ratio and damaged the transmission due to the incorrect ratio. The engine and transmission that were in the GT when I bought it were JDM swap according to the PO. He did not have the paperwork on the JDM engine or transmission. Both looked really clean, however the transmission is noisy and the PO said it slips at highway speed. The fluid smells burnt. To reiterate, I need to know how to tell the rear differential ratio so I match up the front differential correctly when I put a transmission back in. I know it should be 4.444, but since other things have been swapped and there is no paperwork for those items, I don't feel comfortable assuming it is still the original rear. I am starting to have suspicions this car may have been a 5MT car to start with. I'm guessing that information would be in the VIN somewhere. Can someone tell me where that is in the VIN?

I picked up a really nice 98-99 lob limited last week for the cost of moving it outa the guys yard. I was told it had rod knock and sure enough it went bang bang. Pulled the engine, short version is the block is junk, heads are marginal. Looks like done material for future projects. Bought a JDM 2.5 for my year and model from JDM-Alliance for 950. Less than cost of rebuilding a core. Compression is good at 142 across the board, plugs are clean. Pulled front covers and timing belt looks new, idlers are all bright and sparkly. the engine is SUPPOSED to have less than 40k on it and by looking at it I would agree its possible. Upgraded head gaskets and upgraded rear oil cover installed. Im going to run it. The swap engine is not egr equiped so I "should" swap out the intake, drill and tap right head yada yada yada. Questions: Do I have to swap out the intake at all? Will it work without an erg system? The exhaust was left on. The down pipes wrap around the front of the block tucking under the front with an exit pipe to the rear on left. Way different than my lob which drop and go directly to the "Y" pipe. Clearly I won't use that exhaust but does it indicate anything I should be aware of? Any gotchas I should look out for? Cover me Hoss, Im goin in.
