THINKING OF SWAPPING/BUILDING YOUR SUBARU? EJ207 VS EJ257

Hey everyone!
here's a video on some Subaru engines, hopefully it'll help you decide which platform is best.
the video was getting very long so here's a few crucial points I forgot.
The ej207 version 1- version9 platform is best fit for a 93-05 Impreza.
this requires WRX wiring.
The ej257 is best in a 2008+ Impreza.
there is a sepcial version 10+ ej207 that fits into the 200 and upwards bodies and it is three quarter closed!
the average price of this engine is 7000$ usd.

I straight dropped a Ej207 v8 into my 2003 Wrx automatic kept the usdm ecu "could have kept the jdm ecu and utilized the dual avcs." No mods or wiring changes needed, just unplugged the avcs plugs and got tuned. Runs amazing.

[@XD3blaze]

What wiring needs changed to swap the ECU? I was planning on a v7 swap with a jdm ecu and my understanding is you need a different gauge cluster

[@DiLLY_V92]

I highly suggest before stating an engine design has “oil leaks” “burns oil” in general, that you provide a more detailed explanation of where is prone to the oil leak developing, and the cause. Otherwise it is a very vague misleading projection. I think if you dove into detail on WHY they burn oil, or WHERE they a prone to leaking, it would have made the video even better 👌🏼

[@Camotorsports]

Thank you! I'll keep that in mind for next time.

[@teameliteuk2023]

Them issues on a subaru about oil leaks and oil consumption is utter horse shit, if an engine is built properly it shouldn’t leak oil. I have a gc8 running a ej207 2.1 stroker at 554bhp and doesn’t leak or use any oil 😊

[@Camotorsports]

That's great to hear, You did just say it's been rebuilt. In Stock form these engines have a few minor problems. They leak from oil pan and rear main seal The ej207 is the best platform. I have a 257 block with 207 heads myself.

[@aaroncook5713]

that don't leak oil only when they have a head gasket leak . mostly it due to the o rings , it has better gas millage but consumes oil like a Deisel

[@evilclownatwork]

@@aaroncook5713 what o-rings? there.s no o-rings between the head and the deck mate...

[@KevBacon6]

We need some videos of that GC8! I just bought a V8 EJ207 and DCCD 6 speed for my 95.

[@ronnieboucherthecrystalcraftsm]

ANYWAY = GREAT car and video = SUBARU more smiles per miles ! thanks to everyone ! = 68yo subbie hot rodder . RA block has like 5/8th inch thick walled cylinders !

[@bonniehammond9566]

I have 2 hatch backs. 2006 wrx ej255 and 2008 wrx ej255. What motor would you suggest for both cars. Stick with the same ej255 or maybe go ej207.

[@winstonbrowne3167]

The only oil leak that is normal across all the ej models in the ej207 is the valve cover, so all that other stuff u talking about i dont know where you get that info from!

[@rushane1707]

The ej257 is succeeded by the fa series not the fb

[@Camotorsports]

I mentioned it that way because Subaru in 2010-2011 started using the FB n/a version first then switched to the fa20 BRZ/WRX type.

[@ronnieboucherthecrystalcraftsm]

i would love an IAG 2.7 long top series engine ! but = so i brought a brand new EJ207 RA STI JDM - short block virgin in a cardboard box from japan - then spent big dollars on HEADS = ej205 non avcs - brian crower s/s valves - springs - bronze guides special seats and top guide seals ! $12,000 + and counting = just done 6,550 klm running in .

[@IcySTi]

how is the car running without avcs? does it feel laggy?

[@xrsrule]

Just wanted to correct your description a little there. Version 1-4 wrx and STi did NOT use the ej207. V5 and 6 STi used the first iteration of EJ207 with non avcs heads and OPEN DECK block design. The bug eye GDB gained AVCS and SEMI CLOSED block design. This engine is dubbed the S20C EJ207. It also features the strongest rods and factory forged pistons. From then the blob eye GDB STi had the T20C EJ207 which again was SEMI CLOSED deck had some head revisions a one piece long runner intake manifold, tapered small ends on the rods and hypereutectic pistons, gained twin scroll exhaust manifolds and a double cross drilled nitrated crank shaft. The Hawk eye GDB also got the T20C EJ207 engine with further head revisions as the spec c variant was now the group n homologation spec engine. The GRB EJ207 was the first non S20x car to go above the 206kw gentle mans power agreement, upping the output to 226kw. The GRB was the first EJ207 to switch to a W20C engine block which utilised the thickest cylinder walls of any EJ variant, gained exhaust cam AVCS along with totally re designed heads. The pistons were still hypereutectic and still had tapered rods with a double cross drilled crank shaft. From this engine iteration until the final EJ207 powered car only things externally changed.

People having a crack at this bloke video and most of them have no idea what there talking about.

[@MRK-wz8tf]

where do i get that gc8 six gauge. at 3:38

[@Camotorsports]

Hey! I did some research to see if its available, I can't seem to find a option to buy one. It appears to be a DIY made one. I'd assume they put 2 triple pods together.

[@Tomtommi]

The biggest problem by far is the 2.5L head gaskets, they fail even in standard engines

[@TDT0188]

old 2.5l N/A subarus have headgasket issues. any other subaru with an MLS headgasket has no issues and the oem headgasket is good up to 400hp

[@aaroncook5713]

i have had that problem, got a ej20 after blowing two in 4 years

[@jojoaka420b]

Lol mine just went

[@michaelmorley7678]

The 257 will make too much torque for the standard WRX drivetrain, even with PPG gears it will still bust the differentials

[@Camotorsports]

100% Wrx drivetrains are noodles. I didn't think of mentioning that. Once you've upgraded your turbo - 350+ it's best to go with the 6 speed from a Sti.

[@evilclownatwork]

how did you manage to break you're "differentials" with a ppg box?
