so after a year of procrastinating i just orderd a new buschur 2.4 and all new oem components had the head done and now am assembling the motor.

evo420

my next task and the one im having the hardest time with is installing the timing belt. im using a new oem evo 9 belt with stock cam gears. im told this is possible but not sure exactly how to do it. any help would be greatly appreciated

evo420

Intake cam doesn't even look close.

evo420

ok so one should disregard the outer tooth settings and simply set the inner "cam" to roughly 3.75 retarded

evo420

evo420

With a 4G64's taller deck what you need to think about is ignoring the outer ring. What matters is getting the cam positions lined up with the timing marks which comes from the indicated marks on the center ring. In your last set of pictures, Id guess your crank is off for those to now line up though.

If you think about the outer ring not mattering, it doesnt matter if you move the came gear forward or reverse cause you can just offset the opposite direction with a tooth on the belt. Just think about lining up the center. That, and 3.75deg is the standard offset with a 6mm taller block.

it is at tdc i confirmed with a rod on cyl 1.

i inserted a rod into cylinder 1 and positioned this large screwdriver to just ever so slightly make contact/ no light seen between.
when at tdc.

evo420

well i got ahold of buschur racing and was told to just line the 0 mark on the inner cam marks withmarks on cover and advance both cams 3.75 deg. so what ever thats what i did. and now she is in there.
i have to get it past smog first so all stock piping and cat will be going back on till i can get it smoged.

nice progress

evo420

ok i got it all in and running put all stock stuff on for smog got that handled. had some issues , like turbo drain pipe not lining up and leaking
i had taken the cam cover on and off somany times checking timing/valves i didnt notice one of the spark plug hole seals had fallen out. started it up idled ok. let it idle for 10 minutes topping of coolant. didn't see any leaks so i took it for trip around the block, pulled back into driveway walk into garage while its ideling suddenly it starts to stumble and shuts of, so i start looking around and find a massive amount of oil leaking! oh shiii!!. jack it up. looking every where looked like it was coming from back of motor. turns out the oil had been forced past the gap in the vc and head filled up every spark plug hole and over flowed the valve cover what a gd mess
now i need to replace the alternator belt tensioner its squeeking and making some $h!tty noise but other than that i got all my old mods back on

evo420

drove it about 20 miles with with several heat cycles changed oil. brad penn 20w50 as recomended by BR,
set wastegate duty cycle to 0 pulled out some timing and made a pull. 18.5psi-17 and 2deg peak load-12 out top

evo420

set wg duty to 50% and the same 2 deg peak timing to 13 out top which gave 27psi

second graph is a comparo of previous motor except on kill at 33psi
