[quote=”Kreggor” post=39152]Hey Eric, I would love, first and foremost, to see you solve the problem with the hesitation on acceleration — mainly because I have a 98 Outback that suffers from the same thing and I have tried most (but not all) of what you did in your performance videos to solve it, with no luck.
About the performance track, another option to consider would be swapping in the block from a 2.5L 95-2004 Legacy and keeping the 2.2L heads, intake, computer, etc. A lot less work and money and supposedly it’s a high-compression torque machine, akin to what the Honda folks do with the D-series minime swaps. But getting the tranny/AWD system sorted out first would still be best in my opinion. And fuel efficiency is always a good thing to pursue too.
Thanks for all the valuable help you’re giving folks over the internet! And happy Thanksgiving weekend.[/quote]
Even though I have yet to ‘solve’ it I feel that I’ve nailed it down to a transmission issue. I think at some point I’m going to tear the engine and transmission out and ‘refresh’ them. I think it would make for some good video. I just need to get my van going again so that I can have the Subaru down for a bit while I do that. That might be a while though because that project keeps getting pushed back.

One reason why i hate auto transmissions, Can’t say anything other than, my two manual boxes, one on the sr20det and one on the GA16de nissan engines take a beating and still smiles at me for some reason.
We’ve never had alot of auto boxes in europe though, seems to be a US thing.I’d say your dislike might come from a lack of experience with them. It’s also fair to say they eat up horsepower. I would argue that if you had more experience with them perhaps they would be easier to work with. Personally I like driving manual transmissions but at the moment I don’t own one.
I recommend the stock rebuild. Just bought a 2000 Legacy as learning car for my kids. Though not yet driving never too early to learn. Your quality of video would go a long way to helping with my goals.
Thanks and I expect to get dirty:)
JeffDoes the Subaru have some variation of a lock up type differential rear and an open differential at the front? If this is the case would it make it a 3 wheel drive? While modifying to get better fuel economy could it be possible to have it where the front wheels would pull together on demand thus increasing traction?
Hey Eric I’m new to your forum and like the approach you want to take as these are not real economical!
Part of the hesitation is from the archaic computer which does so after stepping off of the accelerator it purposely does so in a manual when racing one you stab the brakes to wash off bits of speed instead of coasting then reaplying throttle to elimate this.
To get around the computer you can get chips to lean the mixture and another old trick is to modify the wires sending the signal from the throttle body back the the ecu to give a false (slightly altered) reading.
When rebuilding the engine as its not an interference engine could you do a bit of shaving to raise the compression a bit then run premium fuel to keep it from pinging and even though you are’nt chasing performance some old school things could help towards a little power benefitting it with more economy as struggling to get 10 litres to a hundred kilometres is pretty frustrating!
I,ve done a lot of researching on forums for the ej22 and ej25 engines for power gains and it gets expensive on these engines but I’ve seen them up near 300 HP n/a many $$$$ spent but all the little cheaper tips they use are what you would find use full.
The cam, poorly flowing heads on the ej22, restrictive headers etc do lots for nice smooth Torquey bottom end but choke them up when trying to overtake or get away fast.
Hope you go ahead with the improved economy project as I,d love to see the improvement as my gen 2 could really benefit!

Thanks for your input. The hesitation with the Subaru was caused by the timing belt on the left cam being a tooth off. I covered this in “The Worst Subaru Timing Belt Video Ever”.
As for a rebuild, this car is long gone I’m afraid. I sold it for 3K and bought my 1979 Fairmont and also a 1993 Acura Vigor. I’ll be doing videos with these vehicles going forward. Aside from that, I had made an amendment to this video stating that investing that kind of time an effort into this car just wasn’t worth it. I’ve always advocated that if you want a fast car, start with a fast car and make it faster. It’s not always feasible to make a slow car fast and it’s often more trouble than it’s worth. My thinking at the time just came from the place we all go to from time to time when we wonder what it would be like to drive something ‘cool’ when we’re really driving a POS. Personally, I’ve been there many times in my life.
Thanks again for your input.
