I'm looking to "UZ" my 1993 Toyota pickup. I prefer the 1uz for it's lighter weight, but I'm in California and doing a 1uz is going to be a challenge due to the multiple cats.

Just wondering if this would work, so that I can utilize the lighter block and fool the folks at C.A.R.B.

ANY ADVICE FROM FOLKS IN CALIFORNIA THAT HAVE ACCOMPLISHED A UZ SWAP IN A 3RD GEN PICKUP WOULD BE MUCH APPRECIATED.

Thank you kindly!

I have a vague recollection of someone here experimenting with 2UZ heads on a 1UZ block.

Maybe JustenGT8 fooled with this and made it work, along with VVTi heads on a normal block (which didn't work).

Try a search using "2UZ heads on 1UZ block" or some such.....
