Falcongary Posted November 9, 2019 Share Posted November 9, 2019 Hi everyone can anyone help? I’ve destroyed my bottom end and need a new engine. I’ve got Subaru Impreza WRX 1994 engine code EJ20GDW4HE. Want to know if I can put any EJ20 engine into my car? Or does it have to be an exact match. Cheers!!

savage bulldogs Posted November 9, 2019 Share Posted November 9, 2019 There's quite a few differences and options to fit a engine in a early classic. Did you want to fit a complete engine and inlet , just a long block , or a bottom end with your heads (so everything matches up with the v1 loom ) Quote Link to comment Share on other sites More sharing options...
Falcongary Posted November 9, 2019 Author Share Posted November 9, 2019 The bottom end with my head sounds like the best option mate. But what one of fit? Cheers Gary Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted November 10, 2019 Share Posted November 10, 2019 Any v1 /V2 full engine (block ,heads, inlet manifold and auxiliaries) will be a direct fit Any v3/v4 long block (block and heads) will be a straight swap, if you fit your watercrossover pipe ,inlet manifold,engine loom and auxiliaries. Any ej20 bottom end will fit if you use your heads inlet ,engine loom and auxiliaries. The only thing with this option is that youd have to find out the piston crown cc (for the bottom end you use) and head chamber size (46cc for v1 casings) . In order to know what thickness headgaskets you need to make the 8.5 1 compression ratio As piston crown design and cc vary over the years /models 😉 Quote Link to comment Share on other sites More sharing options...
Falcongary Posted November 10, 2019 Author Share Posted November 10, 2019 Cheers mate my mind is boggled lol. It’s my first scooby and I want to keep the classic on the road! Could you by any chance point me in the right direction without getting shafted. There’s 100’s on eBay I just don’t know what to do really lol .

savage bulldogs Posted November 10, 2019 Share Posted November 10, 2019 The best option depends on your level of mechanical skills and budget tbh , bud . If you've got the knowledge and equipment ,then rebuilding is probably the cheapest and best option imo . As you end up with a good as new engine. Not trying to put you off buying 2nd hand but Most compatible (reasonable straight swap) engines are anywhere between 26 and 19 yrs old . Few tips on engine identification , to help make sense of my previous post . V1/V2 (92 to early 96) , they have single coilpacks on top of each spark plug , a slanted intercooler and a swan neck turbo inlet (air intake pipework doesn't pass under the inlet ). Straight swap V3/v4 (late 96 to 98) these engines have 1 coilpack in the centre of the inlet manifold (ht leads to the plugs) straight intercooler and a front entry turbo (intake pipework passes under the inlet).your have to fit the inlet/auxiliaries off your existing v1/V2 engine, to the heads of the v3/v4 engine. To make everything else match the car . V5/V6 99 onwards classic have 1 offset coilpack on the inlet but the head ports are not compatible with your inlet . Can be fitted but requires a lot of electrical modification or fabrication. Quote Link to comment Share on other sites More sharing options...
Falcongary Posted November 10, 2019 Author Share Posted November 10, 2019 Cheers mate that info was really helpful and has help me make my mind up on a rebuild! I haven’t got the equipment or knowledge to rebuild myself I can remove it and send it away to be done. Don’t suppose you could suggest anyone or place I could send it could you? Cheers again mate!

savage bulldogs Posted November 10, 2019 Share Posted November 10, 2019 I've never had a quote for rebuilding a engine but I've done a few ,so know how labour intensive and costly the full gasket kits can be . I mention that as I doubt you'll get much change from a minimum of £2k for a full rebuild. I just work on my own scoobies for a hobby , so can't offer to do it for you ,unfortunately . If the prospect of a fairly big bill has put you off a bit, getting someone to fit a good second hand later bottom end to your heads might be worth looking into . If I did ,want someone to build/ work on a engine for me, I'd probably choose Mick at Rm performance in banbury or Alyn at Asperformance (north Yorkshire I think). But if you let us know what county your in and someone else migh be able to recommend someone closer . Quote Link to comment Share on other sites More sharing options...

Falcongary Posted November 11, 2019 Author Share Posted November 11, 2019 Hi mate the engine was sweet had full service on it no knocking or banging It sounded sweet I think it was my LED foot. The lights were red went green put my foot to the floor it went off the clock and when I slowed down and stopped it was a little knocking noise so I headed back home and now when you start it up the knocking is getting louder😤😤 Quote Link to comment Share on other sites More sharing options...
