Recently I got few emails a week about the Tundra rods (2uzfe). Most people email me because they had failure on them. When this happen, the block and pistons are also damage. However, the two bolt main cap usually survived. For some of you havent open up or seen the pictures yet, here is a picture of the 1, 2, 3uzfe and a H-beam rod.
You can see from the picture above the 2uzfe rod (second from the left) is very skinny and small. I was told by my engine builder said those rods are good for 400 rwhp. Anything more then that will suffer destruction and especially worst if tuning is off too.
Recently I had an opportunity to make a rod/piston combo for a customer on his Tundra. This customer is only aiming for 500-600 hp he is doing this for insurance purposes. We installed and tested before shipping everything clear and rotate very well. I also included a set of Clevite rod bearings as a gift too. This customer will be very happy. If you look closely, offset is there too. They are direct bolt on the stock 2uzfe crank.
If you have a chance to visit any local junk yard or engine core exchange center, you already see the Tundra shortblock laying around with broken rod or rods. I am a regular at the above locations and that is all I find from this motor. If you are running supercharger, turbo or NOS in your Tundra, please becareful. If anything that goes would be the rods.
