Actually, you are 100% wrong. Late model U.S. cars are legally required to have an EGR (Exhaust Gas Recirculation) valve for emissions.

Obviously from the above statements you have never worked on either car. I'll give you $5000 when you find me a factory aluminum 2jz. Out of the 25+ 2jz motors I've built, amazingly not one has been an aluminum block. Good luck searching.

Well usually imports they use aluminum block. But about your saying about " Late model U.S. cars are legally required to have an EGR (Exhaust Gas Recirculation) valve for emissions." is not 100% true. Because they use valve overlapping which is also known as the VVT-i to control the valve timing so EGR is not necessary to have. Also the old gs300/gs400 has egr true, but the 1998 and up does not have one i can gurantee you that either one gs300 or 400.

I bought a big Lucus bottle and pour 8 fl oz in a full tank for 1 time.
I have about 25% "Shakes when Idle" now! Maybe the A/C have something to do with it during summer! I will try it a few times!
