90 T4r 4x4 SR5. Checked with number of local shops, majority do not have the specialize equipment to rebuild, rather they purchase created re-manufactured engines and swap. Faced with dilemma, familiar with one shop who rebuild and experienced, quality results, but expensive. Paid $4700 with 2 yr. warranty for rebuild, which included component that would not be included with a swap.
Contacted several local shop who quoted $2500-$3500 with a limited 90 day warranty. Another option, purchase created and install self. If one were to go this route strongly suggest review warranty and disclaimers. I purchased an engine for family vehicle from re-man engine rebuild out of the state of Washington, $1800 delivered and offered 70K mile warranty, and or, 7years, great customer support, this was 9 years ago and engine still running strong. Anyhow, food for thought?
