03 bp5 legacy engine replacement??

[Guest]

Hi, I just bought an 03 bp5 turbo legacy with a siezed bottom end. Had planned on replacing it with a motor from an engine importers but turns out they didnt have the one they thought they did. Havent had much to do with subys till now, anyone know what the differences are between the variable timing bp5 engines and the earlier/different model engines are? In other words is there any other engines that will slap straight in, or just use the bottom end out of? The less work i have to do to get it running the better haha. Cheers

seized bottom end? what part of the bottom end?

maybe crack open what you have and go from there. a new donk could be up to 4k for a replacement, and 4k for a rebuild... what would you rather have..

Try Waiuku Car Spares. They have a few BP's around.

Not sure whats siezed havnt pulled it apart yet. Wont be spending 4k on it though. Dont want to pull the motor apart if i dont have to, would rather just replace it but the engines arent as common as the older ones so if nothing else is a direct bolt in, was thinking maybe could use wrx/forestor/legacy sti/non sti short block with the bp5 heads, anyone see any problems with this? Any difference in the blocks etc?

Hmmm, it will have to be a V7 or later block, but I don't know about compressions with the V7 pistons. Best just to find the right engine.

[Guest]

Ok thanks for that, why v7 or later?

I think because they are using avcs?? I'm just guessing since that was the issue with my v8 longblock, and yeah waiuku do have lots on bp5 stuff just got my exhaust manifold from them for my ez30 project seems they have a few of them lying around

[Guest]

Oh yeah i realise that if i find a replacement to drop in id want one with the avcs, but if i use the avcs heads off the one in the car at the moment is there anything stopping me using an earlier block? Any bellhousing bolt pattern differences etc?

For the extra breather on the block.

[Guest]

Oh sweet so long as its v7 or up it should be the same, will just have to work out compression ratio and check valve clearance. Thanks for that

I would just find the correct engine, and save a lot of headaches.
