I purchased my evo iv about 6 months ago and decided lately am going to stick with it now that have spent too much to justify buying a later model one now.
I purchased it not knowing its history and boy did I find out the hard way, I got it home and problems started straight away, longstory short Crank Walk Victim!!! nasty thing to come across couldn't believe it.
So I purchased a second hand motor courtesy of evo spares in Hamilton, New Zealand.
Got a evo 4 block (probably a bad idea but was short on funds) with evo 8 head on it however it had all the evo 4 internals in the evo 8 head anyway so nothing special there.
Engine had done 112,000ks
New Genuine MMC engine full Gasket Set
Genuine new Cambelt, Balance shaft belt, tensioners, Idler Bearings, Oil Seals, Water Pump.All up $2600 NZD not bad.
Soooo got down to the nitty gritty had a mate help me do it over Christmas holidays pulled old engine through the bottom am trying to find the photos.
Took the engine gearbox and transfer case out together and to be honest the hardest part of the whole thing was getting releasing the clutch and separating gearbox from the engine it took a whole day of scratching our heads until we thought lets get on the net and wallah theres a thread in the next 10 mins it was off lol.
Right found those photos we did it pretty old school in the garage with block and tackle, a jack and axle stands and of course blocks of wood lol.
So I thought while doing this we might aswell do anything else needs doing at the same time.
So here is a list of parts I brought during this mission.....

There was definitely a few teething issues took longer then expected roughly 6 days of solid work all up however a day for bloody getting gearbox away from old engine lol.
Anyway we got it all put back in through the bottom had minor issues with the shed nearly collapsing in the process on us lol creaked and cracked away but held up in the end.
Put all back together then nervously turned the key and bang she started straight away so smooth no lifter ticking or anything of the like, was awesome.
So was then time for dyno tuning this is my first turbo car and the first time ever working on a car that is Japanese manufactured so still am now fairly new to it all.
I was in contact with Phil at dynotech industries in Taranaki, Phil I have to recommend to anybody no matter where you are in New Zealand he is a top guy helped me with any annoying questions I had even before I went to him for service, he has excellent communication skills to like I said was very new to the world of turbo cars and still am, he in a very short time showed me a lot I learnt a lot just listening to Phil and was explained in a way I can understand, really knows his stuff does reflashes and has a dynapack chassis dyno very accurate can not say enough how much stress Phil saved me with advice and carrying work out for me.
So Anyway I got the evo iv down to Phil and was fairly nervous also my first time watching my car in that situation especially when signing the paperwork stating my car will be tested to its mechanical limits today!!!! lol.
Phil tuned it all in (sorry for laymans terms nut I don't no squat about tuning lol_ listened to knock detector and didn't make a single knock during the process only problem being Phil pointed out to me it seems to have turbo shaft imbalance it whines very loud not normal sounds like a jet, however moving he showed me my hubs are all going at the right rate and it made 168kw at the wheels internally stock only mild bolt on mods, was wrapped as standard they come around 145kw at the wheels I believe and so it made 168kw on 14psi boost.
Obviously that's as much as will push it for now under phils advice don't want to push turbo too hard then theres extra problem of crank walk maybe eventuating being an evo 4 and its also my daily driver.
So needs to be reliable.
Some photos of the day....
