I don't think that's right. It should be the same EJ20 that all jdm stis have been using

"The new-generation WRX STI’s current 2.5-liter powerplant needs to be upgraded. Subaru launched the WRX S4 with a new “smarter” engine in Japan first, and then introduced it later to other world markets in the WRX and WRX STI in Japan. The Japan-market STI is powered by a 2.0-liter turbo boxer engine that produces 304hp and 311 lb ft of torque. The new Japan-only WRX STI S207 uses the same engine that’s tuned to get a maximum power output to 328 PS (323hp)."

Could be wrong but there it is.

I'm perfectly fine with my STI. I'm perfectly fine with my Z too.

As long as it don't get eaten by a mouse.

I think that Torque News article got it wrong (other articles on there have commentary that says the STi still uses a variant of the EJ series)

EDIT:
Lol. I shoulda done this to begin with

I stand corrected.. the Torque news article was not the only place I had heard that information, I can point you to at least 1 youtube review of an STI where the reviewer says the J spec STi has the new 2.0. Please forgive a mere mortal for actually believing something he read and heard from supposed "experts" lol apparently there is still a lot of mis-information out there regarding the STi vs the Regular WRX

The Z34 is using the same VQ found in everything, with a dated chassis that is compromised by its dual-use in the G. Without the need for back seats I bet they coulda shrunk it down and shaved a couple hundred pounds, and then we're really cooking. But cost savings/parts sharing is where its at.

OTOH The STi is using the flawed 2.5L turbo thats around 10 years old and still has the same rod knock issue that it had when it came back. You basically need to budget in a rebuild if you're gonna mod it. The platform is also compromised by weight due to being a sedan and growing substantially from the GC8 over the generations.

Neither is really "bang for the buck" and you should be easily able to find good used versions of the same car for substantially less. I think you'd be an idiot to pay sticker on a new Z34 or Sti when you get save upwards of 10 grand for basically the same damn thing.

Factory turbo means you can add power cheaper on the Sti - to a point. With a full liter of displacement advantage the Z will always have more upside if you have the cash. And the chassis is better.

The driving experience - i got the Z because it isn't dependent on electronic AWD assistance and it would be a more raw experience. But if i wanted a second car lightly modded to bomb around in and handle wet conditions, i'd consider an STi.

random:

the STi trim adds way more to the base wrx than the nismo to the sport i think. Upgraded brakes, suspension, transmission, engine, wing. But the wrx might be a better value for certain intended uses. The Z always gonna be more limited b/c its coupe (although apparently some people want to turn it into a comfy DD SUV)

That dated chassis pulls in the 1g family on the skidpad. It can stand to be lightened by a couple hundred lbs, but how is the chassis dated?

When I say dated, i''m not saying it's bad. Dude, I own a ******* Z after all.

But you can't deny the Z34 chassis has been around since '09 - getting into the 9th year of production. That's a pretty long time.

There's some obvious improvements I would like to see. They could shorten it a bit and get the weight down with even more aluminum - hopefully there's a way it can pull double duty with the G . . . i mean Q and still accomplish that.

The interior (at least on my Nismo) has some good surfaces, but still alot of cheap economy like plastic on the top of the inner door panels and dash.

The 2015+ Nismo has Recaros, but the Recaros are only the top half of the Sportser CS - wish they'd give us even more aggressive seats, at least as an option. They already have a relationship with Recaro using super hardcore seats in various GTR trims, and even the Juke has full seats IIRC

The CSC issue - still haven't fixed that damn issue and its nearly a decade

Lighter flywheel for better revability. I know they do it for driveability, but i can feel the VQ wanting to be unleashed in aggressive driving.

I suppose its more accurate the overall package should use more improvement.

People that are deeper into engine mods can probably speak more authoritatively on w what the VQ needs in its next evolution - or if Nissan has access to a better engine. The new Q uses a Mercedes Engine.

In an alternate timeline I wish there were more trim of the Z34. There's a billion variants of the GTR (black, track, premium, nismo, v-spec, blah blah)
Base version for entry
Sport with brakes and some cosmetic improvements/tech package for interior stuff
Nismo should have wider fenders, better brakes than the sport, or at least an option for a bigger package or brake ducting, exhaust/intake/tune upgrade, aluminum or carbon roof, aluminum or carbon hatch, option to delete interior stuff for weight savings, seam welded chassis. They'll never go so far as to stick a 500hp engine in there, but give us some more toys to play with in the options category.

At minimum they should make GTR seats and some fancy pants Brembos an option! Don't get me started on the ******** four colors available for the 2015+ Nismo. I would murder for the GTR Nismo's matte gunmetal color from the factory on the nismo z
