Word brother

Really just charge ya for the time it takes to finish it up brother. Hard to say how long it would take. But start to finish all in all, it doesn’t take me more then 20hrs. So it would be some sort of fraction of that

Its the piston profile that causes the higher comp ratio, you can lower he comp ratio by using a thicker headgasket if you want. There are positives to leaving high comp and lowering the comp. all depends on your goals with the motor.

Ya the plastice mani’s were so scarce. Dealer is the only reliable place to get them. They are pretty cheap

@@TheSubieSanctuary alright thanks man, very helpful video. I have an engine coming next week for my 04 Impreza TS, this video is what I’m gonna use +some other vids and some forum stuff, appreciate the response :)

I haven’t done that exact swap but it would be same process. Match the crank and cam gears with original ones, swap if needed. Swap over coolant cross over and intake manifold

@@TheSubieSanctuary Well, I understand. In principle, it is not a difficult replacement. interesting out of curiosity 😁, how much does your original timing belt kit cost for the 251 engine?

Cool channel you have)))

I would be very grateful to you, if it’s not difficult for you to say. What is the best product against rust on the body? My arches also hurt.(((((

Yes it could be done the other way around. Only things to watch out for: Did your car originally have an EGR? If so it will have to end up with an egr motor. Is your car 06+, then you can not use a 251 due to the avls in the 06+ Hope that helps!

There’s a good chance I’m wrong ik that the motor that’s in my 05 Impreza rs is the ej253 with egr and z25 heads and the motor I got to swap is out of 04 fozzi has ej25 stamp and has Q25 heads I’m pretty good with mechanics and how everything works but still trying to figure out how these Lego blocks tick, no pun intended 😂

@@Littles_garage 05 and under typically are compatible. It may the egr that is the difference in the cyl head codes. Im better with turbo knowledge but definitely dabble a lot in the N/A

To replace your blown engine so that your car works again? These are old cars, find a good domestic engine with reasonable milage is near impossible. The Japanese engine will typically have 1/3 of the milage as the average domestic.

Yes even though this jdm na was dry, they did otherwise get the same crappy HG’s as the domestic na’s. Ive seen jdm na’s come in with seeping hg’s 😭

@@TheSubieSanctuary It’s quite a lot of work changing the H/Gs for MLS ones, but so worth it. That motor would never leak again from there.

@@Mike_44 exactly, thats what i tell the dudes on seeping headgaskets. If ya do them, it will be the only time 😂

Yes for sure if they want to pay for it. Otherwise, with the timing components off it is easy to inspect each bearing. Its what it means to be good mechanic rather then throwing peoples money around.

Absolutely! Exact same process
