        ORRs 2cents on tires & revs & MPGs  -->  I'm running 205/65R15s on the front to keep the same 25.5in Dia' as orig'

& 235/75R15s / 28.9in Dia on the rear to get the RPMs down & MPGs up. I get 70mph @ 3500rpm & 20-22mpg with the

Orig' 2.1L MT4 in my 90Westy. 

                                                                                        ORR ~ DeanB

In 2010, a few mo's after it Became VDubaru, I replaced the Orig' 0.85 4th Gear with a 0.77 & now I get 70mph @ 3150rpm ~
