    Here is the new evo 6 engine for the 5!

    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.
