Since I blew the engine up early last year (2008) and have not had a nibble on the turbo kit that I have sitting in my house I have been trying to think what to do with it my choices are 1 of 2 options - buy a turbo car and when something blows it is easily replaced/upgraded - cost $15k or buy a new engine for the Lancer (4G69) and rebuild that engine.. $4k - $5k
So what I have found is that I can use the rods from a Evo 8 or 9 to go into the engine $400 buys you piston and rods so rods should be half that price
A return fuel line from the same and pretty much the whole fuel system from a evo 8/9 unkown$$
Injectors from a WRX 440cc apparently these are pretty cheap as well $100 for the full set
The crank shaft... I am not sure on it maybe able to be just treated to take/deliver more power which from what I understand is not an expensive job as it is a heat treatment with a protective coating
Oil cooler from a Evo ( this was possibly an oversight for the original setup)
Head swap... it is possible to use the head from a 4G64 as it has the same number of bolts (7) the journals match up etc
also a 4G63T will bolt up as it too has a 7 bolt pattern but some of the water journals need to be plugged - I don't think that will be a big deal so it seems that we can convert this engine to a DOHC only problem would be ECU but if you were going that far with a head swap you would look at changing over the intake manifold fuel line and install a Evo ECU (I think) but just think of all the possibilities of aftermarket parts :shock:
anyway this is just a start point and I will add to it as more info comes available I am using some info from a friend in the states that is doing the same he is aiming for 500hp atw I am not sure I want that much in such a light car
I can post up some pics if people would like a closer inspection of the head
Thought I would post a link instead

also....
4G69 uses 4G63 rod and crank bearings (old news)
4G69 uses 4G64, 4G94 valve guides and seals
4G69 uses the EVO timing belt tensioner which is aluminum, not cast iron
4G69 intake valve = 34mm (4G63 EVO = 34mm) May fit?
4G69 exhaust valve = 30.55mm (4G63 EVO = 30.5mm) May fit?
4G69 uses 4G64, 4G94 valve spring retainers
4G69 uses 4G63, 4G64 head bolts (can use 4G63 ARP head studs )
4G69 uses 4G63, 4G64 main bolts (can use 4G63 ARP main studs )
4G69 uses 4G63 EVO balance shafts (can use 4G63 EVO BS eliminator kit )
4G69 uses 4G63 fuel Rail (can use AEM's)
4G69 uses 4G63 Rods (just check height and length)
+ unique
