    Here is the new evo 6 engine for the 5!
    [​IMG]

    Long story short, young guy picked up this car 4+ years ago. Within a month engine killed itself (not sure why, in the past I have seen waste-gates fail, cars overboost to 28 lbs or whatever no wastegate control gets you, and engines throw a rod out the side of the block). PO decides to buy a fully built motor from the US and install himself.. finds he has no time, brings it to a shop in Edmonton, they have it for over a year and it moves with the same mechanic to 3 different shops. Each one tries their luck at it, after a 5, 7, 8 ECU, followed by a haltech, followed by a link g4, they finally get it running and tuned. Above wastegate pressure the car gets phantom knock, no one really knows why but his exhaust is super restrictive and he is having crank case pressure issues. Car makes approx 360 whp @ 14 psi.

    He brings it home, acknowledges issues, brings it to shop in Calgary who works with well known evo tuner. The shop is tasked with giving it a bill of health, addressing issues which might come up. They determine, with a boroscope, that at some point the pistons have made contact with the valves.

    Obviously, over this time it has been 4 years, PO is tired of the car, decides to part it out, I messaged him to buy the rolling chassis, granted I bring some of my spare wheels. He sells a bunch of stuff, wheels, turbo and intercooler kit as a whole, ECU, etc. Someone wants to buy the head (as it has cams, ported, etc), when he pulls the head from the car, he finds that there is no valve damage at all, no contact.. so the other shop must have seen the valve clearances and assumed it was contact marks. I actually looked at the engine myself with the head off and also didn't see any evidence of valve-piston contact. At this point, he posts pictures on FB group and an engine builder chimes in that the pistons were orientated backwards this whole time. So the clearances for the exhaust and intake on the pistons were backwards. PO still is done with the car, no change in his mind, part out proceeds.


    In rolls me, I am just going to put it back to stock with this evo 6 engine I picked up, an evo 5 trans I had as a spare, and a spare t case which I have gone through and upgraded the LSD fasteners. I have an evo 7 ECU to go in, and I have a factory 6 wiring harness (spare) sitting here that I can use if the old one has been too molested.

    Not a very big update, but I have most of the things I will need for ebo 5, subtract the clutch.

    Painted the heck out of some rusto parts,

    Just used some spray paint on the fins, when I blasted it at the car wash a bunch of paint flaked off exposing copper, which turned green and uggo.

    Polished the heck out of this:

    The place I am renting has pretty poor garage lighting, changed out two of the bulbs for the LEDs

    Finally getting around to things on the 5, parts pile is secured, I don't think I need anything else for assembly.
    As the engine bay had an engine explode in it, then it had the dipstick of the new engine pop out a couple times, it was filthy and not a fit home for the new engine.
    I didn't get any pictures of the before as i was just embarrassed at how gross it was
    Partways through cleaning

    Hood before, see grossness

    Some nice tin snips clearance that I found, with the 4g64 this car had, it also had a rotated turbo and honda civic half rad, as well as some beefcake intercooler. I am not sure for which of those this clearance was done for. The cuts also were left unpainted lol.
    [​IMG]
    This side looks like it was done with a an actual cutting wheel but the other side was full on tin snips.
    After, clean bay, fixed hood insulation. I borrowed a pressure washer from my friend, pressure washed everything, then used superclean and this little electric dishwasher brush you can see in the tin snips thing. Honestly looks like fresh paint IRL afterwards.

    Reposted picture, but I similarly didn't have pictures of the before of the engine because I was also embarrassed how dirty it was. Reminder that this engine was pulled from a running evo 6, compression tested well across the board, healthy running engine.

    I didn't get many pictures of the process, but here is after cleaning, sanding and painting block, etc

    Cleaned and painted spark plug cover

    I had the old exhaust manifold covers from the 6 that were in a lot better shape, I cleaned them and painted them
    [​IMG]
    I also cleaned the trans and t case with a tooth brush, and just wasn't happy with the finish of the cases anymore, so I painted those as well (great masking job).I went to Canadian Auto Paint Supply and they actually had paint for exactly this purpose.

    Time for timing kit, water pump, etc.

    Hooray, timed things, new water pumping things. Those keen observers will notice that the oil pump sprocket isn't lined up in this, but this was after timing was set, engine was turned over a heap of times to verify timing.
    [​IMG]
    I also had noticed the timing cover warped, the plan was to put it back in place with some cardboard spacer behind it and between the cam gears and the cover,
    [​IMG]
    The plan failed
    [​IMG]
    New timing belt, balance shaft belt, all pulleys, hydraulic tensioner, water pump, valve cover gasket set, accessory belt (car had AC removed, would be a real pain to put it back)
