History and Future Plans

To be honest, I never really saw myself owning an Impreza. I've always been a Legacy man. I've had 5 or so Legacy's, two of which ended up with phase 1 EZ30s under the hood. ;)

However, when I saw this little AWD, 5 speed, OBD1 Coupe on Craigslist for 1600, I just couldn't resist.

Little bit of backstory here:
Project Berserker - The Subaru SVX World Network
And feel free to read up on an amazing car while you're there.

Yea, it's kinda beat. Lots of rust underneath, the interior is absolutely roached, and there was a tube sock ziptied over the MAF as a filter... But with under 100k on the clock and a strong running 1.8 I said screw it.

I've been driving it as is with the gutless 1.8L and horrendous 3.90 trans, and I love it. Can't wait to see what a little more power and proper gear ratios will do for it! My initial plans were to drop an EZ30 in it, but I've decided to hold off on that for a while and try turboing the 1.8. I've seen several people achieve great results with the 1.8 block/2.2 heads combo, so that's my plan for now. Eventually I'll get the H6 in there and hopefully boost that as well!
Other than that I've got a 4.111 trans and rear diff from a 97 Outback which I expect to yield a massive improvement in drive-ability. I really hate the 3.90 gears...

Thanks for reading!

Quick question for those in the know:
I have an OBX 8:1 FMU (RRFPR) which I think is a little overkill for my meager intentions for boost. Can I just use a Manual Boost Controller in the vacuum/boost reference line to lower the ratio?
My thoughts are; If the rrfpr sees 50% of the actual boost, it should increase fuel pressure by 50% of its ratio. I.E. making my 8:1 rrfpr a 4:1 rrfpr.
Is this logic sound? Thanks in advance.

Edit: I'm now thinking this WOULD NOT work, since an MBC is more of a boost 'delay' than a 'reducer'.
Also 8:1 wasn't enough, although I'm unsure if that was because my particular FMU was defective or not.

you may not need a RRFPR. for some reason, my AFR's were almost exactly the same with and without it. i would try the car with just boost and no RRFPR, then try out the 8:1 and see what it does to your afr's.

also, since you're taking the engine apart already for head change, might as well just run the 22 block for more torques.

Thanks for the input, GOTJ! Did you also have a 1.8 or was yours a 2.2? I'll try it without the rrfpr regardless, I do have a walbro 255 so...

I have yet to locate a set of dual port 2.2 heads close/cheap enough, so I'm planning on turboing the 1.8 as is for now, then being able to turn up the boost once i get the heads.
And for some reason I feel I've seen far more stories of the 2.2 going pop, probly because far more 2.2s have been boosted.

At any rate, if I really need more torque I've got two EZ30s waiting for homes. :D

Finally back from Mass, I installed my intercooler splitter after work yesterday:




It's hard to tell but the shroud JUST squeakes by the TPS


Unfortunately only one hole lined up in my hood, I had to use seven self tappers. Oh well, looks cool through the scoop.
Up next: Rear Sway Bar!

Strange noises

Hey all, any idea what this sound is???

EJ18 knocking, quiet after warm up? - YouTube

Only apparent when the engine is cold. It literally, LITERALLY sounds perfect when it reaches near operating temp.
Also the video makes it sound... trebly, i guess. It's much deeper and more solid sounding person.

I just replaced my T-belt tensioner and idlers about a week ago, anyone think one of those already failed? I know aftermarket parts are a gamble...

Meh, I'm gonna check the tensioner today anyway, will post results. In the meantime, feel free to offer suggestions...
Thanks!

Edit: engine runs and performs normally, fluids are good, definitely thinking it's the tensioner, won't get to see until later.

Further Edit: it WAS the Timing Belt Tensioner, I threw the old one back in for now and she's nice and quiet. Guess I should order one from Subaru, since the eBay one lasted almost a week...

More Parts

Just picked up this beauty for 80 bux! Never been used, doesn't even appear to have been dry fit. It's a much better inlet port than the stock UP and it's Catless so I'm pretty happy. And it came with gaskets and studs.

New Bumper/AFR Gauge/Clear Tails

Finally got my turbo oil feed fitting..... NOT! It's too small for my feed line, that's what I get for guessing :bonk: I swear I'll have boost some day...

I did manage to modify my new bumper and get it installed, install and connect my Wideband O2 sensor, and swap in my clear tail lights.

Start with this


Cut out a bunch of garbage


Get some mesh, cut it to fit, paint it, and ziptie it in


Yank off the old bumper

I had to cut off the bottom half of my bumper support beam to get the new bumper to fit (and look good)

In with the new, and voila!
Before and after



Finally have a working AFR readout

Had to remove the stock O2 as I didn't want to weld another bung into a manifold I'm not keeping. It threw a code briefly but it's been fine so far. I'll reinstall it when I put the turbo exhaust pieces in.
It runs a little lean at light throttle/cruising. I'm guessing it's a combination of my modified intake and my lack of O2 sensor. It's not too bad, about 15.0 at the leanest and around 13.2 at WOT.
Anybody know if I can safely run a Walbro 255 with the stock everything else (Injectors/FPR/Intake)? I'm ok with running a tad rich, but I don't wanna be at like 10:1 ALL the time. Any guidance is appreciated, thanks!

Nice work on the intercooler splitter, it's coming together for ya.

The loud idle sounds like ej1.8 lifters, this would stand to reason since you said it goes away after it warms up-Whereas the tensioner or pulleys would be always be loud if something wonky was going on. When my car is low on oil I experience the ticking as well, try not to rev a cold engine.

That bumper came out awesome!

Thanks guys, I think the look of the car is massively improved, just need side skirts and rear spats... oh and those sweet 6 spoke RS rims.

Flat4, I definitely have loud lifters as well, but changing out the tensioner got rid of the knocking sound that I was concerned about. It was similar to my 97 ej22 when it skipped a couple teeth, quite loud. It is weird that it would quiet down after it reached operating temp tho...

Oh ya, I'm in Colorado for the week, helping my buddy get his 86 Suburban back on the road. Expect a couple pics of the fun.
Anywho, he's borrowing this POS so that's what I'm driving around in now...

It's automatic :facepalm:

But the scenery makes up for it. These were taken right from his porch!
