Hi guys, kinda new here but definitely not new in the car world. Bought my car in 2011 used and started modifying sound system then slowly went on to mild performance, then all out turbo, standalones and learning to tune on my own. Been one hell of a roller coaster ride definitely. Originally was a 4g18 engine and bolted on turbo with the required supporting mods, but ended up blowing the engine with the rolling launch control(pit lane limiter) feature on my ecu which was setup too aggressively, so decided to go all out while still remaining road legal and decided to do a 4g93t MIVEC build. Originally posted this on Mivec.co.nz forums, but thought I'd share it here as there may be people out there wanting to use my build as reference. It's gonna be a long post with many pictures, hope you enjoy! An overall view of my car can be viewed on izso's writeup at http://www.racenotrice.com/diywaja.html though, that article was written when it was still running the old engine. This thread will be more about the rebuild of my new 4g93 Mivec engine as I proceed and will be quite detailed as I am doing it mostly by myself. I have a very close relation to my workshop and mechanic and will be building my engine under his guidance so this thread will be pretty detailed. I had worked for him before so I actually have some experience building engines, plus my old engine was also built by myself as well. First, photos of my pride and joy! Entered Sepang International Circuit once, a couple of months before my engine spit out it's rod Speaking of spitting out rod, the damage of my old engine. Goodbye 4g18T, you had served me well :( New engine arrived from the chop shop! Came with NGK plug cables, too bad I won't be using them as it'll be converted to K20 COP soon Turns out it's the RS model I've gotten! Notice the rear water-oil cooler. Jackpot! Internals looked pretty clean, heck even the engine oil drained out of this engine was still yellow. Looks like a really low mileage engine Can see there's not much difference in terms of lift between the 2 cams Gearbox code. Couldn't find any information about these online, but apparently they're from the latest model and have a shorter ratio 2nd gear. Too bad I won't be using these as well, sold off the gearbox and bought a long ratio gearbox which is more suitable for turbo and everyday driving. First time holding Titanium valves. They're mind-bogglingly light! Tore down the gearbox and... wait.... ARE THOSE CLUTCH PACKS?! Ultimate jackpot! The gearbox came with Cusco Type-RS 1-way clutch type LSD! Tore that apart as well, barely any wear on the clutch packs, looks nearly brand new!
