- 91 Mazda Navajo 2dr 4x4
I just finished upgrading my 91 Navajo with the upgrade kit from Delta Cams. What a difference!!! Now my engine is so quiet it almost scares me. The performance is up some too. That along with 2.50" exhaust with a 40 series Flowmaster makes for an awesome sound and smooth running engine. I highly reccomend anyone with the annoying 4.0 engine tap do the upgrade. It only took me 3.5 hours with basic hand tools and that includes cleaning up my valve covers really well. If anybody has questions on what was involved just ask and I'll answer quickly. The rocker shaft upgrade is $150.00 well spent!!!
