Default getting 550 rdy

Hey,

Ordered my 550 eprom (upgrading from 440), carl davey adaptors ordered, found some yellow sti for cheap, new injectors o-rings ordered, and the cx-racing fmic en route, can't wait to install everything and have it running!

questions to those who installed the cx-racing fmic, is there a bov flange somewere or i need to customfit one? and you guys ran into problems of any kind?, (herd about leaking couplings) anything else?

Nice, I've been wondering weather or not to go 440 or 550 with my sti. I'd love to hear your impressions on the comparison when you get this all done.

I dont suppose you've dyno'd this setup have you. seeing some numbers would be great

There is a flange but it's in an odd location and points right at the starter. It work if you use a 90 degree fitting.

The clamps it comes with aren't great. Some of mine leaked and I just used regular hose clamps.

If fits better if you cut the pipe in the area behind oil cap and add another coupler.

thx for the feedback!

i removed old timing belt, it was due, but I have a problem with my crank pulley, hope I can repair this without replacing the crank shaft... maybe a new key and pulley will suffice...

If the slot in the crankshaft is worn there's no long term repair unfortunately. Crank needs te be replaced.

JB weld actually holds up really well for this. Set the new key in place. Spread the JB around in the worn out slot in the crank and put a new crank gear on and tighten the bolt before it dries.

I've also tack welded the key in then filed the welds down to get the gear over.

Really the key just aligns it. The 100 ft lbs you torque it too holds it in place.

Ones I've fixed for people years ago are still running.

It tastes like burning

I think the key does more than just align. I believe it also keeps the pulley from drifting out of alignment over time. It would be a fun experiment to line it up without the key and check in a few thousand miles if the pulley moves out of place

It is also possible to cut a new channel exactly 180deg from the damage section of the crank. Although, the crank has to be out to do this anyway, so might as well replace the crank.

The key was broken as the edge of the keyway, I will repair it with a new key, and liquid steel, the pulley bore is good 24mm and key way too... unexpected... I will not open the block, I had oil leaks one behind and one in front. so I took some parts off to find out the hoses under the throttle body were bad and I will replace every rubber hoses in front and reseal the oil pump.



can that hose drops oil here and there over time and buildup a mix of oil and sand and dust over time, the block is so dirty it's unbeleavable! (I did clean the front part a lot)


I recieved the cx-racing intercooler, but it seems I will have more than a blast trying to install this... It's HUGE, I doubt it fits under the bumper...
