EJ22 Swap into SF Foz Part 1

Love the green ... :biggrin:

I won't voice the obvious ... :lol: :rotfl:.

It all looks terrific, NL :cool:.
 
Love the colour! I'll be picking up my car with a ej22 next week hopefully, should meet up for a beer to pick your brain on the swap!
 
Looking good Luva of the Nacha ..... Is the green so you blend in in the bush and you don't frighten frogs off?

Best regards,
 
I should paint the whole car that colour :rotfl:

Sure idw, that would be good. I'm putting it in this weekend so I'll be happy to discuss how it goes...

I was going to ask how long until the rest of your foz looks like the Incredible Hulk but then I got a phone call... You beat me to it in a way.

A lot of modern engines look like this even with irregular oil changes. I put it down to better tolerances, better ring designs and probably better materials used in production that all lead to less blow by. Also the crankcase ventilation system plays a key role in removing that fine misty oil that's no good for lubrication.

My EJ was the same when I pulled the sump and rocker covers. The vehicle it came from didn't looks like the most pristine example of a Subaru either!

Cheers

This engine was filthy on the outside, even after being steam cleaned. Leaks from both valve covers, crank seal, LHS cam seal (always seems to be the LHS that leaks first), slight leak from the rear main seal, even the plug on the rear of the RHS head was leaking. Not sure why but the 2 bolts that hold it on were missing :shrug:
 
All finished, engine running smoothly. Although it was a bit disappointing at first as the larger EJ22 had noticeably less torque at low RPM which was the whole reason for doing it in the first place!

But the ECU has been learning & the new engine has more zip than the old although torque seems to be about the same or very slightly more.

Many thanks to Pezimm & Venom for their valuable help & knowledge doing the swap. And also to El Freddo, Dedman & RSR555 for fault finding the tricky crank sprocket issue...
 
Welcome in the EJ22 world !

You won't need to change gears as much as before, specially up hills and it will keep going even in deep sand…cool !

Did you change the rockers too ?
 
:woohoo: :woohoo:

May it serve you very well, mate. I look forward to having a look at all your work.

No I wanted to keep the engine stock. Plus if I understand, by swapping the cams it becomes interference & I like the idea of an indestructible non-interference engine :lildevil:

No, it stays non-interferential, I tried :iconwink:
 
do you know what the compression of the new combo is?

May explain the lack of torque increase relative to the EJ20
 
compression ratio EJ20 = 9,7:1

compression ratio EJ22 = 9,5:1

my bad.

I thought you'd changed to the EJ20 heads - I just looked back through the thread and you kept the EJ22 from manifold down.
 
UPDATE: It's taken a while but the ECU is learning & I'm now pretty happy with the EJ22. It has noticeably more poke in the midrange & a little more torque at low RPMs.

There's a steep hill near home in a 60kmh zone that the old EJ20J would just barely hold speed in 4th @2000RPM @60kmh. Initially, the EJ22 would lose speed but I've been doing lots of "teaching"...deliberately using a low gear/low RPM/high load to force the ECU to learn. On this hill & any other time I could, esp at 1500RPM, I'd hold it WOT & wind it out to 5000RPM so it learns all the parameters.

It's worked because the other day I had an extra 200kg plus passenger up this hill, I was sure I'd have to change gear but the revs dropped a little then held, even with the extra weight.
 
Good to hear, NL.

Was that in 4th or 5th with the passenger and extra weight?

The SF was always seriously under-grunted with the EJ-20. The EJ-22 would have been a better choice for a 'standard' engine, right up to the present (or an FB version of it) IMNSHO.

If FHI marketing had half a brain, they would offer the 2.2L as standard, with the 2.5L as an extra cost option for those who want or need more power and torque.
 
One year later, I still love this motor.

My Foz now climbs everything without stalling and I can stay much longer in high range, especially in first gear on looong climbs so that the low range doesn't suffer from not being lubricated enough, so no whines yet !
 
That was 4th gear @60kmh.

jf1sf5, that's what I'm hoping lol. & I always protect my LR too, use HR as much as possible
 
That's doing very much better indeed, mate :) :biggrin: :cool:

It's what I really appreciate about Roo2 after my EJ-18 '93 Impreza. That ability to 'dawdle' in either high or low range, while still having plenty in reserve if something goes a bit pear shaped. There just isn't the need to rev its rings off just to get it moving as was mostly the case with Roo1.
