- Welcome to the next episode of the Subaru Impreza build on my wonderfully random channel :)
You can find the links below to most of the products used in this engine restoration.
In my previous video you seen seen me restore the engine bay from a rusty crusty mess into a better than new place for the engine to live. So lets crack on and get the engine rebuilt and running.
First Job on the list was to fit the new rocker cover gaskets, as stated in the video i use a little RTV silicone in the extreme angles around the cams as his is a know area for these gaskets to leak due to the angle not compressing the same as the rest of the flat surfaces of the gasket. once the gaskets are in i fit new rubber washers to the bolts then torque them all up in the correct sequence so as to get even pressure on all the gasket surfaces.
I then moved on to the timing belt cases, its pretty much the same story here new gaskets, washers bolts then torque to spec. I zinc plated and yellow passivated the brackets you see on the left of the casing to add a little bling to the otherwise dull looking plastic.
I then rotate the engine 180 degrees so that i can easily access the underside of the engine to fit the manifolds and engine mounts. The manifolds were mounted with brand new fixings and gaskets to ensure there are no exhaust leaks, The exhaust system is also heat wrapped in titanium heat wrap to try and keep the engine bay temps down and protect the oil filter and sump from excess heat.
Once finished on the underside i rotated the engine back to the top and made a start on fitting the coolant lines,vacuum lines and fitting the air conditioning compressor,alternator and power steering pump.When these items were fitted and torqued down i fitted new intake manifold gaskets with a nice bead of sealing compound to ensure an air tight seal then torqued the intake down to spec.
After that it was just a case of fitting some small gaskets, clips and fitting the fan belts as you can see in the video fitting and tensioning these belts isn't a hard job.
Then came the fun part hooking the engine upto the crane and lowering the engine into the bay for the first time in so many years. I was terrified of scratching any of my lovely new paint but im glad to say the engine went in without any fuss or drama and no damage was done. After this it was a simple case of bolting the gearbox to the engine,bolting the engine mounts,hooking up the electrics,vacuum lines,sensors, adding some fluids and we were ready to turn the key :)

A little History
The project in question is the engine bay in my 94 Subaru Impreza WRX. As i can be heard saying in the intro of this video i love impreza's and i wanted a rust free one as all the UK ones suffer from lots of rust issues so in 2004 i imported this car from Japan and it was totally rust free when it arrived all those years ago. It has a couple of blisters here and there now but thats to be expected when living in Scotland.
Anyway im getting off track, I was having lots of fun driving the car at full boost everywhere until 2014 when the thought popped into my head " lets go for more power" so i took the engine out and begun the process of having it all upgraded, better gaskets, race bearings, forged pistons, con rods etc etc then life got in the way and the engine was put to the side and the car was stored in a shed for the past 5 years.
The initial condition of the car looks horrifying but its only a thick layer of dust and crud on it and there is a good layer of carnuaba wax separating all the crud from the paint so a quick pressure wash and she'll be looking good again but for now the focus is on the engine bay and engine.

A new addition to my videos from now on will be a water mark and my channel name popping up in random places throughout the video as im getting rather tired of people re-uploading my content as their own i hope you guys understand.

Hey Guys, As you have probably noticed already i have updated the channel name and logo. The channel is no longer Really Random Channel it is now RRC Restoration. Just incase you were wondering why the water marks in the video still say Really Random Channel. Enjoy.
Hi, what model is the steering pump from? Part number?
It's amazing how much power can be pulled from a small close tolerance engine. Modern engineering at it's best. Little note ** I had the closed caption on when you started her up and the closed caption said [ MUSIC ] well hey that say's it all LOL
I allways watch on mi pc with headphones, the sound of the engine is so good.
Quality of work is always top notch! You caught up and past me with subscribers months ago!
That engine is so compact. Very impressive to see it come together.
Proper job. I found Subaru engines surprisingly easy to work on.
MegaDirtyberty it seems to be an ups called motorcycle engine, I thought that when I saw the valve covers
Subaru and Honda are gems to work on. Super easy and super reliable if maintained :)
@@jeremygibson9006 129%..top favs at work as they go together well and perform well if cared for ..Honda and Subaru 👌
Everytime an engine fires up for the first time, it seems like black magic! Thanks for the video! :-)
And that thing does have a lot of belts. :-P
This is what I love to see. The detail on everything is amazing, even the wrinkle red on the manifold! You did a superb job and can’t wait to see what’s next! 👍🏽
Make the noise..."beep"
Nice work fella 😎
Loving the project binky reference :)
@@RRCRestoration Ah, Glad to know you're a man of culture! A year late, but too good to not acknowledge :)
Right up till i watched this video i never knew that Subaru used a flat 4 design.
Thanks for yet another great upload, your attention to detail and end results are pure magic to watch.
Thank you for firing it up. So many videos show all the work and never get to hear it.. Good job.
Sorry for the grammar, my English is very bad, that's why I use google for translation.
For other videos I have already written: I am very pleased and very first with what Sorgfallt you work. The workshop is always very clean. The tool is very clean and very well maintained. In videos of others I am always disappointed. There it is messy. Basics are ignored. I learned locksmith. You notice that for example. To tighten screws crosswise. They use torque wrenches.
It is always a pleasure to watch you.
Thats what you call clean professional work 👍
Just found this channel, it's showing me what I'm in for soon on my own car. I'm currently powder coating my GDB WRX manifold and rocker covers to the red crinkle finish. Gonna be refreshing the gaskets and doing the timing belt.
Awesome, Good luck with your build! :)
@@RRCRestoration Thanks! Looking forward to your next video.
Am finally getting my engine rebuilt! Thought I’d watch so i can justify the massive cost involved 😅great vid btw!
There's only one way to do it... the right way, and that's how you do it!!!! Congrats... she's sounding nice....waiting for the next one!
I like your method of opening bags; neatly with a razor blade. I've observed that in all of your videos. I have my own thing where I always use scissors, no exceptions. I never tear things open. Your videos are like therapy, watching straight up junk get beautifully restored. Next equipment purchase should be a vapor honing cabinet.
I do this stuff everyday and it so therapeutic to watch and learn more. Awesome trick with the valve covers gasket sealant on the tight spots. I have great luck with Hondabond, Ford gasket, Ritestuff and Cnc other gasket sealers in small quantities in just the right spot. Awesome resto, mate. Cheers👌🤘
That is a beautiful engine, looks and sounds gorgeous in your restored and clean engine bay!!
Best series on RUclips currently!!
High praise indeed :)
Great video, gives me more appreciation to how the Subaru engines are made and maintained.
For the cam covers, the RTV goes in the corners on the head, between the cylinder head and gasket; not in the groove between the cam cover and cam cover gasket. Intake gaskets go on dry, no sealant/RTV needed.
Hey, thanks for the advice and with a name like MrSubaru I'm certainly not going to argue with you as you clearly know your stuff ;) But my engine is dry so im happy with my use of sealant... even if it was excessive haha.Thanks for leaving a comment.
Great job mate! Tremendously enjoyed the video. Looking good and sounding good. Can't wait for the next one!
Thank you ,Im very glad you enjoyed it :)
The firing test it's a very magic moment. Congratulations!
That's the part i dread every time i build an engine is the first firing lol. Great , clean looking engine. Great job.
Haha yeah same here its a mixture of fear and excitement all rolled into one
@@RRCRestoration hahaa yeah i close my eyes and open my ears as wide as i can go.
What a heck of an engine...I always thought my Yamaha 660 with 3 outlet and 2 inlet valves and double carb on a single cylinder was complicated...
8-0
Great job, thx for the vid!
:-D
Thanks a lot for the clear view on tensioning the belts for the crank pulley. I’m going to be installing a new lightweight crank pulley and this helps a lot on how to re-tension everything back down again. Great video!
No problem glad my video could help you out ;)
Bloody smashing. Great project to see coming together, and I love how meticulous you are. If a jobs worth doing you certainly do it well. Workmanship you sadly do not often see these days. Excellent channel Brother. God bless.
As with all your projects, you do them right the first time. Great job!
Love that Scooby rumble! I surely do miss my WRX and STis'. Maybe one day I'll get another. Impreza is looking sharp with that awesome combo of white/red/black. Proper gold wheels would finish it off nicely!
6:05 Nice Owl!
She’s coming along nicely 👍🏻👍🏻
Great little build you for this WRX. And I do admire how George was overseeing the operations. 🤣
Nice work, greetings from Holland!

Great rebuild, and detailing, looks very complicated with all the pipework etc. Looks great in the engine bay. Guessing because it is a flat four adds a lot of external pipework?. My engine rebuild is limited to an old mini, due to the crankshaft to gearbox idler gear bearings disintegrating.
Many thanks for sharing and best regards from the Black Country.
The coolant crossover pipe is quite normal as any other japan designed engine in that era...
Alot of other extra piping is the one connecting waterpump to the turbo coolant reservoir and plenty of crankcase breather point...about 6 in total if not mistaken (2 on each rocker cover, and 1 for each side of engine block)
Not to mention the massive intake manifold and fuel hardline underneath it...
Anothing daunting task is installing that super long timingbelt (double the length than a normal inline engine) and plenty of belt idler bearing and the need to line up 5 pulley marking point (4 camshaft+1crankshaft)
I wish that I wasn't lead to believe that higher education was the only way in life when I was young. I'm sure this is not always an easy job but it definitely is fascinating to watch. Wish I learned something like that.
I'm enjoying watching your good video.
I support you in Korea.
Waited so long for your videos! Amazing job as always
Amazing work as always. I love watching your videos
Well done! I love my Subaru. So easy to work on. So easy to get parts.
I really want to buy one, but in my country it is extremely expensive and difficult to find parts
Mate, you're bloody good.
Great work as usuall!! And your English made big progress,so I understand every word and can enjoy your videos even more !! Thanks !8-))
when I assemble the engine I always use copper grease, it is temperature resistant and prevent bolts seizures
someone might have said this before but to me you sound just like Colin McRae , no disrespect intended in any way.. and the videos are great, love the motorbike stuff. take care and have a great day....
Thank you very much its a great compliment being compared in any aspect of lilfe to Colin Mcrae, the mans a legend! :)
I always love the first fires....its so exciting.
Yeah me too, its a mix of excitement and terror for me haha
Absolut awesome video cant wait for the next instalment
Clean engine..that's something i can lay my eye's on everyday of the week..really love your work.. Merlin of Restoration's
Thanks for your kind comment :)
@@RRCRestoration you're welcome my man
That lawnmower engine will last many many years now 👍
Oh la la ... echt fetter sound .First Motor fireup always makes me 😁 . Awesome & interesting Video 👍🤘
Another great job and top quality video👌🏼 . . . .I wish it didnt end lol. Looking forward to the next one!👌🏼👊🏼
Me encantan tus proyectos, greetings from Costa Rica!
Nice. Started on the first try. You're either lucky or really good. Your videos point to good.
Thanks :) ive built a few engines in my time ;)
Great work as usual, loving this.
Pretty cool bro, looking good so far man
All that work I would have put some threadlock on those bolts.
Why would he?
That's one nice lump of an engine, looking sweet!
Thank you, Glad you liked it :)
Love your work mate, but this is a refresh more than rebuild if that long block is staying as is.
The engine was fully rebuilt and forged before i started my RUclips channel so unfortunately the rebuild wasn't documented but i can assure you its fully rebuilt i wouldn't go to this much effort for an engine thats not rebuilt :)
stunning work - warm congratulations
Amazing Job !!!!
Absolutely brilliant job loving it
Thank you very much :)
I have the same Snapon torque wrench. I love that thing.
thanks for sharing your skills and project ideas with us !!
Thank you for watching :)
Great video as always, keep up the good work
Stop hogging all the cleverness...leave some for the rest of us!! That's awesome, great job.
Hi, loved the engine build, very impressive. So many of these type of videos are ruined with music so you miss things like torque wrench clicks, etc. Keep it up.
Al fin estaba esperando el vídeo para dejar mi like por el perfecto contenido
Look at all them belts.
so lot of work........ ! Good job !
Another top vid, no dilly dallying, top man 👍
Thank you :)
Great job as always 👍
George is awesome.
Another excellent video, as always top work and very well filmed and explained. Looking great, can't wait to see the final assembly.
Thank you very much for your kind comment :)
Hi RRC another cracking video, thought we were going to see you turn steering from lock to lock to bleed power steering, once it's had its run in period & oil change & tune that's going to be a rocket ship!!! got to ask being a numpty all 4 cam belt wheels looked different to each other !! looking forward to the next 1, ATB Wayne.
Nice to see you again :). Glad you enjoyed this episode. Yeah i didnt bother bleeding the steering as i had a million other checks to do in the limited time i could run the engine without coolant before the internal temps got too high. Lets hope so just hearing that scooby rumble makes me so excited to drive it again! Good question they are all different so that you cant possibly mix them up when they are off, they are all marked as well to make doubly sure such as L IN ( left inlet ) L EX ( left exhaust ) etc etc.
Sweet engine build.
Great work sir
from Indonesia
Thank you :)
Love the sound of a Scooby engine. Job well done 🙂
Looks like brz intake manifold thats becomeing mor common now
Ive been waiting for this
U have a best channel 😍😍😍
Wow that sounded great. Is that the stock exhaust, I don't recall if you mentioned it. Also, did you paint the intake manifold yourself? I'm curious how that'll hold up; looks insanely nice though!
Thank you, The exhaust is a custom made stainless steel one from the cat back, it releases the iconic Subaru rumble without being too loud :) Yeah i restored the manifold a long time ago with red wrinkle to the exact same finish as an STI manifold. The wrinkle finish if done correctly is extremely tough ;)
Sound and looks great
The engine parts looks amazing,and you make a very good job in this motor. But i think the AC clutch stuck by the paint. :D
Holy crap. If a disassembled an engine like that it would take 9 generations to put it back together lol.
Haha, Thanks for leaving a comment :)
Awesome!! Really nice work!
Thank you :)
Excellent job! Question: Did you consider anti-seize(well that's what I call it) for the Exhaust Manifold bolts at all? Also aren't steel bolts into aluminum prone to galling and also seizing up?
Love watching your work! Look forward to the run down the road!
great work! sound is awesome - thanks =)
Looking good
Master of perfection 😍😎❤️🙏😮
Great video, I would have used some new Group N STI engine mounts to stop the engine wobbling around, also makes the gear shifts a whole lot smoother.
Damn why didnt i think of that! Thanks for the tip i guess the engine is coming off its mounts again sooner than expected. Thanks a lot :)
Really Random Channel then might as well do the transmission and pitch stop while your at it. The four in total really transforms the way a performance Subaru feels and drives for very little to no increase in NVH and not a huge outlay in cost with the benefit of being oem parts.
Any tips on restoring the throttle body??? I am about to do the same on my 2002 Wrx! Thanks!
Good engine
Love your work 👌👍
I don’t know much about the Subaru boxer engines, but that sounded awesome! Dare I say, it reminds me a little of my 6th gen VFR800. Only much stronger and deeper of course. Is it the firing order?
Hello, I like how your engine and car turned out. I was wondering since it has been 3 years how has the exhaust thermo wrap held up? I was told not to use this thermo warping cause it absorbs water and will assist in rust accumulation or quicker deterioration of the exhaust manifold. Have you found this as an issue?
So far its been perfect, still a nice tight wrap, clean, and as far as I can tell there has been no degradation but tbh the car isn't really out that much and it only comes out on dry days so I wouldn't say I really give the wrap a fair all weather testing.
I'm doing the exact same with a 94 gc8 jdm Impreza just now. I got as far as MOT pass then engine has died a week later. Rev counter danced all over the shop then engine cut off. It cranks but doesn't start. I live in Scotland and need advice on best people to look at engine please? Any tips or help greatly received. I replaced cam and crank sensor with no change.
Do a video just like this with the ej 257 sti motor. I love the vid
Hi this is what I love to see.Where did you find the parts manual and repair manual ?
Because I bought a1997 GC8 a few months ago,I also want to repair it (engine and body) but I cannot find the information.Can you help me?
thank you!!
Sounds and looks like my wrx I need to know is that a ej205
Good work but personally I'm done with that engine and the dreaded cyl 4
Great Content Guys! Much appreciated. Is that a crack in that hose at 17:06 ?
