i know its alot of work...but what would the advantages be to more lift on the STi cams being put into a wrx head and block?

i'm fairly stock but i want to do some mods that not everyone does. this seems like a cool upgrade and I know upgrading cams helps some even with out the AVCS.

For how much work is involved with installing cams I wouldn't just do STi. The STI cams do however flow a lot more uptop but if I were going to do strictly cams I'd save and get something better.

It not only is a lot of work but pretty expensive. The cams are only part of the expense. You will need either buckets or have to pay someone to fit the buckets you have or the valve stems to set the clearance. If it's a high mileage motor you might need valves or at the least a valve job. If it needs a valve job it probably needs valve springs or guides. If your paying to get it done you won't like the cost. It's better to wait for a rebuild or if it's daddy's money just blow it up.

yeah, i working on putting together a hybrid set up and I asked my builder if it would be worth the money on buying the sti cams. He told me that you might as well spend the extra money and buy complete avcs heads to go with the block and not have to mess with the problems that you could run into with sti cams in 2.0l heads. As said above^^^^.

Both valid points.... the guy who built my motor for me (as I didn't feel comfortable tqing the heads and setting timing) has a million buckets sitting around from previous jobs. As long as he had the correct buckets around he swapped them, if he needed a different one he had to order them. I think I needed three buckets he didn't has and they are like 25/each or something.

BIG PROBLEM for me guys... Got my hybrid up and running more than a week ago and has 350 miles on it now. Well when i got home from a drive around the city today I noticed a small oil spot under the car. My worst fear has come true. It is leaking oil from the passenger side camshafts somewhere. For now all I know is that there was an accumulation of oil under the timing belt cover on that side and when I popped the cover off I could see oil residue all around the camshaft sprockets. I dont know exactly where it is coming from yet.. I did use STI cam/oil seals.. Is that my problem? Was i supposed to use WRX seals? Any info is appreciated.

The cam seals can be a bit tricky, you can re-use them but you need to be careful about putting them in. Its like the main seals, you don't want to push them in too far, they need to be placed just right.

dont ask me how I know. If its just your cam seals you may not be in that much trouble. I use wrx seals personally on my usdm sti cams in wrx heads.

OK, when I bought my new short block it also came with the STI engine gasket set. The only WRX gasket type part I ordered was the rocker covers... Anyways I am assuming that the heads shop that put them together for me and bolted them to my block used the new STI ones that came with the short block. I am taking it there on Monday, I am leaning/hoping that this is the problem (Cam seals). Any ideas on anything else it might be? Im sure I tapped and plugged the cam holes correctly so I am kinnda stumped.

It will start right away if you installed them correctly. Let me correct that, it SHOULD start right away. But no tune is needed right away. My poor cam seals are leaking though!

i put a little RTV around my seals before I put them in. You may want to do the same, just a very thin coating.

Update: Well I got the car back on Friday from the mechanic and he said that one of the cam seals was not in all the way correct. None the less he replaced both seals on the passenger side and said it looked good. I drove it around with him and it was fine. Less then 1 hour later... OIL leaking from the same spot. (Dripping off bottom passenger side timing cover). I brought it back to them and he said he took his time and really does not think its the cam seal. So here is my question. If the cam seals are in correct and I am leaking oil from the plugs in my cam shafts, how can I fix it while there are still installed? Any ideas? Like some kind of weld over the plugs or maybe JB weld ? Lastly is there some kind of oil seal/gasket material I can place over the plugs, then let the cam gears seal on it? Please throw out some suggestions. I still find it very hard to believe that it is leaking from the plugs, they were installed really well I thought

You need to check. I think the sti and wrx cam seal are different. Maybe the shop didn't have the old ones to realize the difference. I think they seal on two different places between the avcs pulleys on the sti and the regular pulleys on the wrx.
Your belt won't last long once oil gets on it.

Need to check what? The STI and WRX cam seals are different. They put brand new WRX cam seals from the dealer on this second time and still leaking. Are you suggesting that they put them in the wrong place this time?

Bump because I think I'm having the same problem.

Are the insides of the cams pressurized with oil? Can leaking plugs really be the source?

I'm losing oil out of my driver's side timing cover

Lance on your setup I put the plugs in with red locktight. I would be very surprised if its coming from there but I guess anything is possible.

Working on eliminating variables at this point. I've already torn it down (including removal of gears and belt) once, I'm hoping to definitively find the problem on next tear down, or a kitten dies.

It's a lot of work but clean it up real good and run it for a short time and look at it. Keep doing that until the oil shows up. Don't wait till the oil is everywhere.

The buckets are basically going to give you your different valve clearances. Once you put the heads back on you have to measure the valve clearances and uses different buckets accordingly.

Now how you do that is beyond me cause I did not put my heads on. The shop did that.
