Be sure to not over torque it on, 15lbs at most. bob |

Re: Knock Sensor code 22
I might add mine was corroded on my 2000 2.5.
So I bought new and then cleaned up the mating surface on the block. I still get a code, but my engine seems to run well. 听 Sean G ________________________________ From: larryalofs <alofs@...> To: subaruvanagon@...

Re: Regearing 3rd & 4th gear after conversion
Good point Eric, there is allot of truth to what your saying. I'm just a happy traveller. I've had mine for 4 years and put over 100,000km on it but am adement about going ahead with the conversion. My stumbling block at the moment is how new to go with the engine. I almost bought a 2006 2.5i SOHC yesterday but was told not to. Something to do with the ECU and the fuel delivery of the 06/07 2.5L engines. I don't want my conversion to get too complicated for my first time. I've been researching this Subaru conversion process for two years now and just when I think I know everything I need to know to go ahead, I get broadsided with a caveat I wasn't prepared for. Sometimes I think it's better to dive in somewhat ignorant and then deal with the issues as they hit you.

Re: Regearing 3rd & 4th gear after conversion
Sounds very interesting. I've always wanted to migrate to a 5-speed tranny mainly because I've too often tried to shift into a gear that wasn't there. My concern would be cost and at what stage of development and reliability is this venture at. I have no doubt that it is possible, since you have already done it, but at what expense.

Knock Sensor code 22
My receintly installed ej22 in my 88 Wolfsburg has developed a code 22, knock sensor. The sensor was loose on the block and the sensor could easily swivel. Is this normal or should there be firm contact between the sensor and the block? is there a torque value? I have a new sensor and it is as loose as the original. The attaching bolt may not be original but does bottom out allowing the sensor to move.
Thanks in advance. Doug Fresno 88 Wolfsburg |

Re: Regearing 3rd & 4th gear after conversion
I had planned on taller gearing with my 6.17 ratio tranny running an ej22 and even went the extra step and bought a 0.73 4th and 1.18 3rd gear sets. The best decision I made was to do the engine conversion first to see how it drives with stock gearing. I'm doing 3750rpm at 60mph in 4th and the power is just adequate! My gearing is the same as with the stock 2.1wbx (in australia stock syncros have a 5.43 ratio) Any taller and I'd struggle up hills and overtaking. Now I have some expensive gearsets sitting around for nothing. It's not too hard to drop out the engine and regear the trans if you're unhappy with your stock gearing but it's pretty expensive to build a gearbox upfront and find you're unhappy with it. Like others have mentioned good old rubber gears work at treat!> To: subaruvanagon@...

Re: Regearing 3rd & 4th gear after conversion
Go to: syncro.org. And you can used the gearing calculator to figure what you want with the tire size you will use and different gears n engine power band. Have fun!

Re: Regearing 3rd & 4th gear after conversion
Thanks everyone for your responses. I'm quite satisfied with what I've heard so far and all your rationales make sense. Better arguments toward leaving the tranny gear ratios alone and make up the difference with larger rims and tires. The experience in this group is very much appreciated and all your inputs are welcome. Since money is always a bit tight, looks like i will keep my hands off the tranny and put my money in a rim/tire upgrade.

higher 3rd and 4th gears are not neccessarily better. two cases.. one guy raised his gearing in hopes of better fuel milage as he was spinning something like 3,800 rpm at a good cruise speed. His fuel mileage got worse, not better, going for lower rpm's at cruise speed. ( and 3,800 is not that bad on a 6K rpm engine anyway )_ another case ...I insalled a modified gearbox into an SVX Syncro I had built for a guy. He raised 3rd and 4th .. and in my opinion kinda ruined it. Sure ..with a very tall 4th you can cruise at 75 + more replaxed than with stock gearing. .. but how often does one get to cruise that fast anyway. the real bad part though was.. I'd be drivin' nicely in 3rd ....50ish and rev's were too high for relaxed goin' down the road.. shift into 4th ..lugging . Shift back to 3rd ...more rev's than ideal. There are no 'holes' in the stock gear like this.. the gap between ratios is very important. if one wanted to raise the over all gearing in all gears ( and thus not affect the gap between gears ) that would be fine.. say 10 % worth ...like with taller tires. The gaps between the ratios are quite good the way VW set their manual trans us .. and ...they also match a fat wide torque curve .. which both a waterboxer and a subaru engine have. ( in a wbxr...there's not all that much power ..but you are strong in the power band from about 2,800 to 4,400 rpm , roughly .. subaur is the same way .. good power at say 2,500 on up ..to over 5K rpm .. that matches stock gear ratio gaps very nicely.

As an aside, having ripped the coupling teeth off of the first gear sets of probably a dozen 915 transmissions when fed by much more than 200 - 230HP and 200+ ft lbs of torque I'd suggest caution employing them for a 210HP/200+ ft lb application. While it's possible to massage in some 928.xxx.xxx parts to make the thing less prone to explosion it's still possible to do significant damage if you're not careful. I haven't used a 915 in anything for literally years; I prefer a 930 or G50 filled with Swepco 212 if it's hot or going to be run on the track, Swepco 201 otherwise. -- Dr. Christian Kennedy chris@...

Re: Regearing 3rd & 4th gear after conversion
Yup, I think you guys are on to something as I'm leaning toward the 16" rims with the "Subaru/Vanagon" conversion I'm about to do. Truthfully spoken, my concern was really the higher output Subaru engine linked with the lower HP rated VW transmission.
