In early February 2025, my wife and I found IG Diego Engine & Trans. Inc when we were looking for a place to have the engine of our 2006 GMC Yukon rebuilt. Gabriel and Diego were very helpful on deciding what kind of service our truck needed. We were quoted a price before the engine removal and inspection, but when the mechanics disassembled the engine, they discovered more damage to other internal parts. IG Diego gave us a new estimate and, even though it was a lot more than what we were thinking, we decided to get the job done with them. We liked the fact that they were really clear about the price of the new parts, including the engine block and the labor charges. In just two days, they completely rebuilt the engine and had it running like new. We have had our Yukon since 2008 and we were excited to know that it will continue running, with a brand new engine, for many more years. We ended up paying $6,270, but it was worth it! Update: On June 12, 2025, almost 5,000 miles more since our GMC Yukon was fixed, we went back to IG Diego to get the suspension control arms and ball joints replaced. After 18 years on the road, these parts needed to be replaced, too. Once again, we were

HORRIBLE experience with IG Diego. Full rebuild from them lasted less than 30k miles in under 2yrs on my Toyota Pickup. Their warranty only covers 18 months with no option to extend said warranty. I was having a bad misfire after the rebuild and took it to them for diagnostic. They claimed I was using “bad gas” that caused the failure. I only get gas from Sam’s Club or Chevron, so I knew this was a lie. So after nearly $4000 spent at IG Diego, they said it would cost me another $2500 to repair the motor they rebuilt. I had another shop remove the heads to find the actual cause of failure. IG Diego apparently used the cheapest no-name pistons and rings which had failed in 2 cylinders (pictured). The shop also found that a recent coolant leak came from a hose on the block that IG Diego had claimed to have changed at an additional charge, which I paid. I thought I was hiring a competent shop that specialized in motor rebuilds, but they use the cheapest components they can find and blame the customer when they fail. There were even more issues prior to the misfire such as, leaks, false diagnosis, food/drink left in my vehicle after repair, and surprise charges and conditions that w

IG Diego Engine and transmission are my go to for engine service. I have a 2003 Celica with a built 1ZZ, Three years ago I purchased a “professionally built 1ZZ engine from a company called MonkeyWrench Racing”. They promised that the motor would run great, instead the engine leaked, issues with misfire and oil consumption. I looked around for a great engine builder and IG Diego was that. They corrected the issues I had with the previous motor while strengthening it at the same time. The pricing was better and reasonable than shipping my motor back to the MWR for them to “fix it”.
