Default Are there any issues swapping from EJ251 to EJ254?

Well, I don't have the time to do a full v3/v6 jdm swap until my supra gets put back together. So, in the mean time, I need a quick "inexpensive" solution to the seeping head gaskets on my ej251. I think, if the short blocks will interchange, that a new(ish) ej254 from a non-turbo bug eye would get me by long enough to sort out a jdm swap and get the supra back on the road.

I just wanted to know if anyone knows if I can run the 175hp 02-06 nonturbo short block with my phase2 sohc heads and be able to transfer all my sensors and accessories directly?

I searched for "ej254" but came up with nothing...

Sorry for the lack of coolness and propensity for non-glory. Lol

Everything should bolt right up and it should run fine. Pretty common to swap shortblocks around and reuse heads and sensors.

I assumed as much but didn't see anyone really mention anything about it. Maybe just cuz is that easy. I wanted to make sure before I spent the money only to find out nothing wild swap from old to new.

But thanks!

I've done it twice and it's worked great. Easy swap, no issues.

Thanks bud!

I wonder how much brand new short blocks are costing these days right from the dealer... I love the idea of a zero-mile block and some worked heads with some delta cams right about now... Lol

bringing this one back from the dead.

GF just lost her timing belt on her 01 2.5RS. I want a cheap/quick swap. There is a '04 outback (rear end total) local for cheap.

Is it possible to use the EJ254 entirely? Not just the short block? ...assuming my valves are toast and I don't have the time right now to rebuild the EJ251.

Thanks

It will work. You probably will have to swap the complete intake manifolds, a few things may be different.

Likely some of the plugs are different. I do not know specifically which ones, but subaru likes to change the plug styles with years.
