Any reason not to go stroker?

So I’ve got my EJ22T torn down and inspected, crank needs replaced do to blow out keyway, and cylinders are at the wear limit, so a bore is in order. I was looking at the .020 over forged Wiseco pistons but the price for the stroker pistons is about the same and since I gotta buy a used crank anyway... to stroke or not to stroke, that is the question?

The rest of the details on the build include: EJ25 DOHC heads, EJ20G intake & injectors (440cc), VF-24 turbo, TMIC, 3” TBE. What I’m shooting for is a good drivable street car, not monster top end power, off boost low end is important and I think the stroker idea plays right into that. I know the DOHC heads might drop a little bottom end, but the CR will stay near the stock 8.0:1 or maybe slightly higher and the VF24 is a quick spooling turbo that’s still 300hp capable. I plan to start boost at about 12psi (below fuel cut), then add EM / injectors and ramp up from there.


Your thoughts?

If your into a full rebuild anyways and your after some low-end, the only reason not to do a stroker is the rods. You need EJ25 rods to match whatever phase crank you choose. Phase 1 has 48 mm rod bearings. Phase 2 has 52 mm rod bearings.

Phase 1 EJ25 rods are *said* to be among the weakest factory rods, so you might budget good rods into the build.

maybe go with a 257 bottom end instead? all told a 2.35 build shouldnt be too far off of a used 257.
if youre looking for a new crank, you can buy my whole 22e shortblock with 148k on it for $50. its in seattle.

Finding a good used crank and rods from an EJ25 could take a while. Seems like they used to be all over the place.

I think budget or time are the only reasons not to go stroker.

The rod I bent probably bent under a timing belt mishap.
