Rb20det Slugish After Water Pump Change

[GTS4-32]

Hey guys, after my water pump started leaking i went and bought a new pump and thought id put it in myself, as it didn't look that hard to do. I stripped everything to the crankshaft pulley, took all the belts off without touching the cams so the timing wasn't going to be touched. Everything was fine, replaced the water pump without problems and put everything back the way i took it off.

So when i started the car, it seemed to be fine, idled well and everything was normal, until i took it out for a drive...it felt so sluggish in every gear, its as if the power was stripped off me! It sounded fine though, no knocking or pinging, just had no power.

I run a safcII and my usual readings with knk sensor is 30 or so with full boost, when i ran it yesterday, it read over 220. Whats going on, could it be the timing? Im clueless to this situation, any ideas on what i would have done wrong. What could i do to fix it? Any suggestions would be much appreciated..

Cheers,

Steve.

are you sure you put the cas back on correctly? in the same spot and the same tooth. it sounds like you timing is retarded.

[GTS4-32]

Im sure i did, because i found that it only goes in 1 way. If it doesnt go in that way it doesnt go in at all. Am i right?

Not necessarily. Get a timing light and check the timing.

[GTS4-32]

Yeah i dont have a timing light, so i guess ill go down to my mechanics and have them check it out, So its definatly my timing thats out through the cas, is that what you's are saying?

I would say your cam timing is retarded by one tooth, and thats also retarding your ignition timing by 7 deg

(i think)

[QWK32]

your right in saying that it will only go on one way. but if the half moon shape bit/pin on the end of the camshaft is shapped off it will go on anyway. but if the pin was stiill there you should be right. what about the position of the cas bolts in the slots. are they about half way, even a bit to the right in the slot. thats about the spot your after. i think its best you get a timing light on it anyway just to make sure.

i agree with adriano i recon your cam timing is out

yea apperently i missed a tooth when i was putting the timing belt back on. I just got the cas timed with the belts current position, its got my power back but its not quite 100%. Need to get it tuned again.
