Thanks for clearing that up. I would like to see the pics of the different gears. Also I just dismantled a 2.5 phase 2 engine and both pulleys were metal... any one seen this? Is this a 2003 + engine? All the ones i've worked on up until now are plastic and metal.

Ok im confused: Is the 99 2.2 engine a type 2? I have a 98 2.2 (type 1) and the manifolds that you say you just swapped are no where near the same. The type 2 vs type 1 manifolds are 1/2 to 3/4 wider and a slightly different bolt pattern. What up yo? I thought type 2 2.2 started in 2000 and were only in Imprezas. Any help on the years and type engine clarification would be greatly appreciated.

Thanks 360. I saw another thread where someone put a phase II 2.5 >> in a 98 legacy. It looked like from his article that the phase 1 intake bolts to the phase 2 2.5 so are these the same too? Is it just the 2.5 dohc that has the different bolt pattern?

Yeah having the timing belt off two teeth would cause all kinds of "fun" noises on startup. What did you do about the exhaust? single vs dual port issue? Y pipe from 2.5? Another question: all subaru sohc pulleys are the same tooth count and are completely interchangeable with out messing up the timing ratios? Forgive me if this has been covered 100 times I am new to the swapping of subaru engines ( 2.2 to 2.5 etc) My first couple subarus and the ones my customers owned were legacys so i never had to mess with the engines just cv joints and wheel bearings

OK so the 2.5 phase 2 on 2.2 phase 2 both have the same intakes? the earlier ones had different bolt patterns as i remember. Are the cam sprockets the same number of teeth but different timing marks for the sensors? If not what timing belt do you use? 2.5?

I have done the early 2.5 dohc replacement several times. Wondering if the later 2.2 is a drop in, plug in and go replacement for the 2.5. Oh yeah can it be done with the phase 1 engine with some tricky mixing and matching of manifolds injectors etc. This is my personal car so im willing to experiment too nervous to do it on the customers cars. Thanks

Yeah I have three good phase 1 2.5 lower ends and 2 good sets of heads off a phase 2 2.5. The pistons have the deep square recess so i think the compression ratio should work.

I recenly dismantled my friends forester engine to find a way overheated piston which was cracked and burned on the top side. Has anyone heard why this happens. On old vws it was a timing/ octane issue. Any ideas?

Has anyone tried this? putting 2000 phase 2 heads on 98 phase 1 block? Thanks

Wondering if anyone has done this? I have several good phase 1 lower ends and several phase 2 engines with good heads. case looks like it would work:pulley location and size look identical head gaskets look the same. compression ratio might be different due to piston shape. Any thoughts? thanks
