How To Identify Jdm Evo Engines With Ease!
HOW TO IDENTIFY A JDM EVO 1-2-3 4G63 ENGINES WITH EASE!
A lot of people are surprised when they find out that ALL EVO engines didn’t come with CYCLONE intakes, but the JDM supplier swears it’s an EVO motor! Well most likely you bought a jdm gallant vr4 or a JDM Mitsu van engine!
Even if your motor has yellow top (540cc injectors) and the correct turbo ,evo III 16 g (or variations for evo 1/2) that still doesn’t mean it’s an EVO motor!
I will assume you are buying a long block or combo tranny/transfer case/ecu/harness. If you are buying just the block/pistons/head I will update this ‘how to’ with even more specific info!
What to check for before you buy the motor:
1. Visual inspection quick reference:
-all EVO 1-2-3 have a black CAS sensor part no: MD184529;
-all EVO 2-3 have black color revised ISC sensor;
-if the engine has a cyclone intake it is not a evo motor;
-evo 3 had stock white color dip sticks only; (but it can be any color of course)
-evo 3 had silver top valve cover; (but it can be any color of course, red top I saw them before);
-evo 2-3 have a specific TB that is part number MD322173;
-intake manifold should be silver with short runners;
-there should not be a radiator fill cap on the water neck;(it’s located on the radiator);
-the IGN coil pack should be placed upwards on the intake man;
-the turbo for an evo 3 should be stamped: 49178-01470, for EVO 2: 49178-01460, and for evo 1: 49178-01450; (OEM turbo part numbers, of course they can vary)
-yellow top injectors should have a 540 mark on them or 585 mark on some RARE models(585 some U.K models);
2. More detailed information:
-The timing belt cover should have the part number stickers on them: on all evo 1-2-3 motors you should confirm MD191805 for the top cover, and MD191807 for the bottom one;
-THE MOST IMPORTANT detail it’s the IGNITION COIL and POWER TR: All evo 1-2-3 motors ignition coils should have a silver sticker between the no 1 and 4 coil reading MD192126, SHOULD also have RED and BLUE only wires to each coil; and the connector should be a Triangle shape 3 PIN!!! IF it is different then IT IS NOT an EVO MOTOR!
-the Power Tran on evo 2-3 models should only have 3 pins followed by 4 more and you should be able to read MD192127 on it!( not sure yet what PR on evo 1, I will check and update)!
-another important clue it’s the injector resistor box that should be engraved: MD099628;
-If you happen to buy the ecu/tranny combo then the ecus in evo 2-3 are ALL EPROM and should all read MD322364!
-the transmissions VARY but here is the trick to find out if it’s an evo tranny or not:
All transmissions should be stamped- ex : W5M33-2-ABCX!!!
The 4th letter of the second part (marked X in my example) represents the mounting location(vehicle type) the tranny is designated for, and should always be the letter
“ E” (evo lancer) any other letter M, K, or D represent different vehicles:M=Galant etc etc;
This is it for now, this paper should give you more then enough info to identify different evo 4g63 engines. I will try to keep this updated, because I have tons of more info about these early evos! I’m trying to locate some pics also!
