Engine out: timing belt, what else to do?

[swamp]

Hey all

I'm planning to pull my engine soon to do the timing belt. Just need some advice re what else to do, shopping list etc. Car in question is a 95 gf8 wrx, with 240kms. Stock, td04, going for reliability>power 

 

So far I've decided on a Mitsuboshi timing belt as they're affordable at repco and supposedly (mrsubaru1387 on YouTube) that's what Subaru use factory. Plus an Aisin Waterpump, also oem going by mrsubaru1387. Is it worth changing Idlers pulleys etc or will I only know that when testing them for play? 

 

I'm going to replace the Headgaskets with mls ones, I see there's 0.6mm ones 11044AA4839/11044AA482 are the part numbers for those. And get the heads/block skimmed as the car has overheated before and I don't want to take any chances. Plus I've read on here it isn't too expensive to get done. 

 

I've read on Scoobynet replacing big end and main bearings is important too as well as a bottom end rebuild, but I'm not too sure about this...

 

I would like to do the clutch, it doesn't slip or anything but can't hurt to right. I'm thinking about exedy oe replacement as I've read it's slightly more aggressive than stock which is nice. 

 

Gonna get the seal and gasket kit too.

Also look at maybe doing the cam seals, and don't forget the rocker cover seals
Look at replacing the rear main seal and resealing the rear kidney plate. 

I'd do the clutch, since you're there, and they're not too expensive.

Probably reseal the sump while you've got it out too. 

 

I just installed those subaru 1.6mm Head gaskets on my engine, they were $270 from the dealer. 

If you've not doing this in the next couple of weeks, I'd definitely buy it all from Partsouq/Amayama.

I'll definitely do all those seals, cheers. I'm gonna look into doing it all slow and carefully with the big seal puller tool, don't want to damage anything, clean up any surfaces with a wire wheel drill attachment. 

 

1.6mm, are they the best? I will not be doing anything really quick, no rush, never done this before so will be doing it slow n steady haha.

I did everything on mine as the full seal kit with head gaskets were cheap off partsouq.

 

I have the MSL head gaskets off a v11 if they would work for you that I didn’t need.

@Gripless I'm not sure if v11 would work, that's like ej205? Mines an old v1 haha.

[Gripless]

Yeah by still same bore and EJ engine. 
likely just a few more holes for oils and avcs etc in the newer ones. 
 

won’t be direct parts match unless you had MLS originally. 
 

nz gaskets likely has the outlines of you want to look them up. 
 

also go with the cast impeller water pump. 
i got the cast one for mine. Most aftermarket were pressed steel and they don’t pump as well.

I have a feeling the newer ones have thinner head gaskets? Not 100% certain on that though.

Genuine timing kits and engine seals are usually only marginally more expensive than aftermarket. I'd recommend pricing up both. 

There's a TradeMe user called ejparts that has sourced me genuine parts for less than the dealer prices.
