T'subaru Posted May 27, 2010 Share Posted May 27, 2010 Looking for parts info for my ej20g engine. Even Subaru does not recognize this jdm engine and I want to aquire seals, gaskets, timing components and water pump etc prior to installing in my L series wagon. Any help would be greatly appreciated. Mark Link to comment Share on other sites More sharing options...
NoahDL88 Posted May 27, 2010 Share Posted May 27, 2010 Don't quote me, but I believe that most of the WRX stuff will work for that engine, the older 2.0 stuff that is. Tex will know, He has an EJ20 in his RX. I'd wait for someone else to chime in before you buy the parts, but I'm pretty sure there is a US counterpart to the JDM engine Link to comment Share on other sites More sharing options...
suberdave Posted May 27, 2010 Share Posted May 27, 2010 timing set for a 98 2.5rs will work. the US WRX belt is the same. WRX or STi water and oil pump will work. us WRX spark plugs do not use STI plugs WRX oil filter. 98 2.5rs intake and exhaust gaskets. WRX front crank seal 98 2.5rs cam seals i beleave its 96 25rs valve cover gaskets. not sure on that one this is just a list off the top of my head. i am sure on all but the last one. any others that you need?

LeoneTurbo Posted May 27, 2010 Share Posted May 27, 2010 Use all seals and gaskets (except head gaskets) of a MY96 Outback 2.5 (the motor with hydraulic lash adjusters). Use turbo gaskets of a USDM WRX, also waterpump and oilpump of a USDM WRX works. Use the DOHC timing belt as used on USDM 2.5 DOHC engines (ie. Outback, Impreza RS; Legacy GT) up to 1998. So basically what dave says. If you never need specific parts numbers for JDM engines, I have the original factory parts CDs so I can look them up.

T'subaru Posted May 27, 2010 Author Share Posted May 27, 2010 Thanks for the help guys, your awesome! It was getting frustrating chasing a ghost as far as engine numbers goes. Mark Link to comment Share on other sites More sharing options...

Once I install the engine I will need to source engine externals like afm? waic etc and as shown here I do not have the knowledge of what will work from other usdm models. As always the knowledge here is greatly appreciated! Mark Link to comment Share on other sites More sharing options...
T'subaru Posted May 27, 2010 Author Share Posted May 27, 2010 Another question please, would you guys recommend I stay oem on the above mentioned parts? Thanks again, Mark Link to comment Share on other sites More sharing options...
LeoneTurbo Posted May 27, 2010 Share Posted May 27, 2010 From my point of view (and experience) original Subaru parts are the way to go. One remark regarding my and suberdave's posts: that only applies to EJ20G engines from the Impreza WRX built between end of 1992 and early 1996. If you have a EJ20G from a Legacy (to be recognised by 2 bolts per ignition coil where the EJ20G WRX has only 1) you need a different set of valve cover gaskets. If your engine is a late Ej20G (built between early 1996 and early 1998, to be recognised by the ignition coil on the centre of the intake manifold with plug leads) you need rocker gaskets from a contemporary USDM EJ25DOHC engine (the one with shim adjustable valves). So there isn't something as 'the' EJ20G, there are three versions which all have different valve train concepts! (even four if you also consider the pre-1996 EJ20G RA engine).

suberdave Posted May 28, 2010 Share Posted May 28, 2010 his engine is a Legacy EJ20G with 2 bolt coils. thus the valve cover gaskets are different. as far as Mass air flow sensor (AFM) i have one from a 96 EJ20G. let me know if you need one...

LeoneTurbo Posted May 28, 2010 Share Posted May 28, 2010 For this engine you need: 1X 13272AA050 GASKET ROCKER COVER LEFT 1X 13270AA050 GASKET ROCKER COVER RIGHT 2X 13293AA001 GASKET ROCKER COVER PLUG HOLE Mass flow sensor for all early EJ20G engines (up to 1996) can also be found on a range of USDM engines (Legacy 2.2/2.5 1992-1998).

LeoneTurbo Posted May 29, 2010 Share Posted May 29, 2010 4x 2 per side Nope, 2.... On each side, one plug hole gasket is integrated in the 'big' gasket. That's only on Legacy EJ20G engines built after 1991. By the way, if you have problems sourcing gaskets in the US, I might be able to able as they are readiliy available from dealers here.
