You could write a book about building subies. No joke. I think it would sell. Even the guys who might never actually build a subie but own one would probably enjoy it

[TMTFish]

Gonna send this video to the newbies who ask instead of me having to explain it

[miloduebendorfer]

One thing to note that’s important is 07+ LGT/OBXT, 06+ FXT and 06+ WRX have D25 heads so if you put a RA shortblock in you are gonna bump up compression to around 8.7:1 and require a tune!

04-05 XT, 05-06 LGT/OBXT have B25 heads (same as STI) so no change in compression with RA block.

[brianmerrill]

That silver hatch you did is a sweet little beast.

[zindrickburns]

You posted this helpful video at a horribly unfortunate time in my Subaru career lmao💀 gonna be taking notes

[yarukineez]

Dude that's so cool that you worked with RSD on this!! Looking forward to that feature on their site!

[MrMcbear]

This came at such a great time. My 2018 sti only has 30k miles but, im starting an IAG 750 engine build now so by the time the stocker is ready to retire, I'll have something to drop right in. Thanks for the amazing wealth of subie knowledge.

[ElectricHellion]

Can't tell me how much this video just saved my ass, took apart the motor I'm building to red loctite the oil pump and figured out I had swapped parts from another motor that's using JDM parts and was running a JDM intake cam gear. Thank you so much

[mattv.]

Great list! One note, because I didn't hear it mentioned. 08 Forester XT does not have the factory oil cooler, similar to the WRX of the same year. I learned this recently when ordering parts for an external cooler.

[qvenom]

before this video, i was afraid to blow up my engine....but now i am more reassured...SOMEONE out there will watch this and know how to fix it!

[HEROHIRO]

Tanner out here doing wonders for the subie community, appreciate you homie!

[edgardomontanez]

I have a 2017 subaru sti and the engine started knocking but it only knocks in between 1k-2k rpm at idle. no knock at idle and no knock at after 2k rpm what do you recommend to do I've been recommended a full engine rebuild, buy a short block and swap the heads, get it professionally done at a mechanic shop but I wanted some more insight on what to do. I changed the oil and I didn't see any metal in the oil.

[johnlexus]

I am so grateful you walked me thru my rebuild last year, my sti runs like a new

[viko]

I don't and never had a Subaru, but I suddenly got the urge to rebuild one. The docs you provided are so good.

[macoakes]

Smeedia just out here doing gods work all nonchalant. We commend you brother!

[green_bugeye]

Do ej205/7 & ej22
In europe we love our 2 and 2.2l 😊
as usual amazing video! You stepped up audio and image quality so, so much!
Looking forward to all the next videos

[jeremyhipp]

Dawg you're saving me this week. Spun my first rod bearing this last month and am devastated. Your tear down video and now this are perfectly timed man. Thank you!

[jacobstephens]

Saved the video to a special playlist for hopefully the distant future lol. Good stuff as always brotha

[jordanhenderson]

I love your collaborations with Rallysport, they're the my favorite place to buy parts from especially since they're based in SLC!

[TheCheezSlice]

this video literally could not have came at a better time for me, currently just finished tearing down my STI and this is exactly what i needed to feel confident in getting it back together properly. youre the goat
