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.

There will always be plenty of differing opinions on the board. I've read here for over 5 years and learned a lot before I decided on an upgrade both in engine size and make trans changes. The gearing in the VW trans is optimized for a VW waterboxer engine. If that's not what you intend to run, and presumably it's not if you're posting here, you'll have to work through a lot of posts and a little math to help you make a good guess as to the right direction for your van. Take the time to outline how you intend to use your newly robust vehicle. If you're solid there, you'll be able to sort through everyone's opinions and find the few that address your requirements. That's what I did. Everyone here is passionate but they can't know what you want from your Westy.

Thanks for your advice, it's much appreciated. There seems to be a mixed consensus on this issue.

My '91 Westy/Syncro is running a 3.0 conversion w/16" rims and a higher 3rd/4th gear courtesy of Lucas Hofgard in Boulder. The higher 3rd works as intended and the gear spacing between 2nd/3rd is not an issue when driving in town. Even here in the Southern Rockies at 7000 feet with the higher 4th gear I can climb almost any hill at highway speeds and maintain 60/65 in 3rd on those occasions where I need to downshift. From my experience, I'd recommend both changes with a 6 cylinder engine but your 2.5 may have different requirements and your location may present a different set of issues. If your trans is in good shape you can leave it intact and add 16" rims to see if that gives you the upper range you're looking for on the highway. Then tackle the gearing at another time if the rim/tire choice doesn't give you everything you're looking for.

Hello everyone, I'm a newbie here with my first question. I'm about to sink a 2.5L SOHC Subaru into my '91 Westfalia. I've been reading about some people recommending that it's best to regear 3rd and 4th in my Westy tranny to accommodate the new engine. What are people's thoughts on the pros and cons or even the necessity of doing this?
