Does anyone know the exact weight differences? If not, I may end up going with a 1uz and 3uz heads. Even though its .3 liter smaller, the 1uz seems to have stronger block, stronger rods and better pistons. The only reason why I wanted a 3uz is because of it's slightly better specs, and it hasn't...
The only problem I have with the 1uz comes from the reliability side of things. I am hoping to keep this car for a fair while, and considering the engine is already around 10 years old, I figured the 3uz would be beter in the long run.
Thanks, thats good to hear. I've heard a lot of different things about the 3uz, some saying that is just as heavy as the 2uz iron cast, and that its bigger in size than the other models. Not much seems to be known about them. It's probably safer to stick with the 1uz.
I am considering a v8 swap for RA28 celica liftback. I know some people are already swapping for a 1uz-fe, but I want to be different - I need to know the dimensions and weight for 3uz-fe. I dont want to be sacrificing handling by puting a heavy engine in a light car (i will be lightweighting)...
