Hi all, second time poster and long time lurker here.
With 207,000+ miles on my drivetrain it's about time for me to refresh. I've decided to go for an engine/trans swap (I have the EJ205 with the 4eat trans atm). I found a JDM EJ207 v5 with JDM 5MT transmission on eBay for $2500 but was hoping to build a stroker engine.. that being said whenever I search "EJ207 stroker" all I find is comparisons between the two different engines.
My question being: Is it possible to use an EJ207 v5 (or any of the EJ207 versions really) for a stroker build? And if so, which 2.5L STi crank should/can I use? Also, I assume the rods and pistons I'd use for an EJ207 stroker build would be the same kind as I would use in an EJ205 stroker build, but clarification on that would be much appreciated.
Another question: I read online (can't remember which forum) that the EJ207 ECU's can't be tuned until v6 or v7, so was wondering how I would go about getting a custom tune? Would it be easier for me to source a standalone ECU for tuning purposes? If not what are my options?
Final question: OBDII as I understand it wasn't standard in JDM Subarus until the 2000's, and most even then will not work in the US for emissions purposes (unfortunately I live in a county that does OBDII test for emissions, so if I source a standalone ECU for tuning would that also allow me to have a functional OBDII port for emissions purposes?
Thanks so much everyone,
-Robbie
