    Which engines are compatible for my 1991 Z34 lumina

    My suggestion to you is to do all you can to stay with a replacement LQ1, if you choose to do otherwise you'll have to deal with the electronic side of the issue. For '91 the trans behind the LQ1 is the 4t60-e, now that may not seem to be much of a concern but the ECM in the car is programmed for the LQ1 & the 4t60-e. You look to drop in another engine of choice & now you have to reprogamme the ECM to accommodate that replacement engine. The mem-cal inside the ECM housing is specific to the LQ1 for that year & that trans.

    How to lower a W-Body ( Gen 1, Gen 1.5 )

    Old post but I think that was me circa 2001. Heres my coilovers after I pulled them from the car back when I was in college. They were terrible and I pulled them off forthwith.
