- Especially when doing merges for our customers with old GC8s we often get the question, what is the difference between the EJ205 and the EJ207 engines? In this video we talk about the biggest differences of the two and give you a simple breakdown of both engines.
If there are any differences that we missed, hit us up in the comments below!

We hope this comparison is helpful. Anything else you want to know about EJ series engines?
I live in australia and I have an My 99 gc8 it has an ej 206 in it any idea why somebody chose that engine instead over the ej205 is it stronger or any benefits at all?
@@Turbovanilli typically when we see those situations it is just price point and availability. The 206 at one point were practically being given away and the My99 engines have always been a more valuable/“expensive” engine. I don’t know of any advantages there would be running the ej206 over the GC8 block though. Are the heads from the GC8?
I am the owner of the SF9. EJ205 merged and 6 Speed swapped SF5 Forester that these fine gentlemen built. It has the mods listed in this video and the car absolutely rips. Shes a real head turner now that I am back stateside. @OkiSubies Thanks again, cant wait for our next project.
Great video! Love the channel, keep it up!
Thank you!!!
Great video
Happy New Year
Happy New year!
Love these videos man. I've had a legacy BH5 EJ 208 gtb JDM import to the UK, with twin turbos, was quirky for sure, the "Valley of death" between 3k-4k revs was really noticeable in 4th and 5th gear. Now I have a BP5 EJ20Y twinscroll, much smoother, but feels less fun somehow. I'm trying to swap in a EZ30 and turbo it, but it's not cheap! Much love from Scotland 🏴
Thank you for watching! Really appreciate the support!
Yeah the ez30 is an amazing platform but can be pretty costly. I always wanted to build a hybrid EJ20Y using a 2.5L block and EJ20Y heads. Still would have torque and parts are plentiful! Maybe you can try that?
@OkiSubies I've already got the ez30 donor car, but when I take the EJ20Y out I could save it for the next project, thanks 👍
@@DundeeBambi15 oh nice! Once you go Ez30 turbo you will never go back to the ej20 platform 😂
2002 wrx With some simple bolt on mods like downpipe and electronic boost controller and a tune would it perform well or should I go with a bigger turbo setup? Thanks
Hey mate, would be awesome if you could do a video explaining the differences of jdm grb ej207 vs worldwide gr ej257 as well as the differences of the grb 207 vs a aus spec blob eye ej207. As I’m currently importing a grb at the moment. Shout out from Australia
Oh that would be great! We will try and get together something for you!
What type of price point can you find like a bugeye 207 engine for compared to a 205? My car has 210k miles on it and I'm curious if the engine goes how much more it'd be to swap a 207 in compared to just replacing with the factory stuff
I would like to know the differences of the intake/exhaust ports between ej20x dual avcs heads and ej207 heads
The difference between the heads differ from year but the version 7-9 and the ej20x heads are very different. Cams different, sensors different, port size, and as you mentioned AVCS. The EJ20x are very similar to the ej25 heads though and also the version 10 and up ej207’s
what about the ej20g closed deck block
Great info guys. Is it possible to put ej20k heads straight onto a 207 short block or do the heads need porting to match the short block?
We have actually done it with no chamber matching! We used ej20k heads on a GRB short block with a 1.2mm head gasket and it performed great.
@@OkiSubies oh nice I've always been interested if it would work
I bought a usdm 02 wrx with a supposed jdm motor swapped into it. I was hoping to see if there is a way to tell which one I have without disassembling the motor.
It is most likely a v6 long block or Legacy engine. First I would start with the casting numbers on the bottom of the heads first. For the block I am pretty sure you would have to remove the timing cover unless you can tell from the number on the back of the left side block.
This is a great right up that might have some answers for you.
www.clubsub.org.nz/forum/index.php?/topic/41534-ej205-ej206-ej207-ej208-short-block-identification/
can you show a jdm ej205 from a 08 14 wrx single avcs
We could do something similar to it but the 08-14 WRX in Japan actually came with the ej20x with dual avcs similar to the BL/BP Legacy.
Can we drop the ej207 sti short block inside ej20x legact gt twinscroll motor? Can the ej207 work with stock heads and cams of legact gt
Yes you sure can! If you have the newer one from the facelift Legacy you could even use the full long block and just install the Legacy manifold. Main difference wiring wise is the exhaust side cam sensors. Pre facelift is two wires vs 3 wires and air pump on the facelift models.
Any thoughts on the EJ204 (Legacy is a 165 Hp, EUDM version) ? Differences compared to the JDM version ?
I owned a 5-speed manual transmission Legacy BL5 with the AVCS version of the EJ204 that made just shy of 200 hp. That car was very rewarding to rev out. It had a very audible VTEC-like engagement at 6,000 RPMs up to the 7k RPM limit. The power bump was actually noticeable. I sold it to go turbo, but boy do I miss that car!
Hello, I'm still waiting for you to post a video about the difference between EJ20G and EJ20K, or have you already posted it but I didn't see it?
No not yet😅
We haven’t had an ej20k and 20G at the same time yet. Sorry for the delay!
If I use an aftermarket ECU, is it possible to swap in the newer EJ207 from GRB/VAB into the GDB chasis? What kind of mechanical modification is required?
Probably you will need to wire the exhaust avcs
It would be a lot of work. The sensors to the GRB are Hall effect (3 wires) vs the GD’s reluctor sensors (2 wires). Then as @hazoorule mentioned you also have to wire the exhaust avcs solenoids and cam sensors. For the throttle body it would probably better to just use the GD manifold or you would have to wire in the electronic throttle body and pedal.
@@OkiSubiesWould the GR short block work with GD heads?
Is it possible to use a ej207 short block with usdm ej205 heads ?
It sure is!!
Difference between the 207 turbo vs usdm ej257 turbo? Im planning on upgrading from my td04
The biggest difference is displacement. Ej207 is also a twin scroll turbo after the blobeye and the internals of the heads are also different. The EJ207 also revs out to 8000rpms🙂
Hello, I have a 1997 Subaru Impreza 2.0 turbo, left-hand drive. I don’t know whether it is EJ20G or EJ20K. Can you make a video explaining the difference between these two engines?
Ours would be about the RHD platform but that is a great idea!
thanks a lot@@OkiSubies
Beautiful GC.
VF30 starts to struggle after 7000rpm anyway, no need to push it much pass that point.
Light blue injectors off an ej205 are 440cc
Thanks for the comment! 440! Gotta remember that one😅
That is a good point on the vf30 or any other stock ihi turbo.
I would say there’s no point revving past 6k with the VF30. I have a 2001 bugeye STi, and the turbo is gutless above that RPM. Unless you increase the timing advance significantly. I have a 100LL avgas tune that enables exactly this.
@@ericn7698 Definitely agree, but I was more interested in the ability to bring up the RPMS, not for power but just wondering if the ej205 would fail lol. Only reason is for the technical courses we run on Gymkhana it is faster to stay in gear than to shift up right before a corner.
What about the ej204 ??
The short block should be practically the same as the ej207. Heads would be different because the 204 comes twin turbo and non AVCS.
