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?
