Well I have found some great information for your 3sfe and 2vzfe people. I was looking into all that I can to do the head and I have found a different lifter bucket to use instead of the stock ones. The 1SZFE motor which is found in cars like the Yaris is a 1.0L 4 cylinder. It uses shims underneath the bucket instead of up top. Also this bucket is about 20 grams lighter per bucket then the stock ones. What this will do for you is allow you to rev a little bit higher with the weight being less there. these buckets will work on a 3sfe and a 2vzfe since they both use the same stock buckets and valve springs. I am working on getting part numbers for all the bucket shim sizes so that you can have the proper bucket in each cylinder.
Good news, but wouldn't anyone wanting raise the rpm -> head limit just swap to 3s-gte, or 2jz-gte avalible hardware?
(I'm just assuming a 2vz-fe head has the exact same springs/retainers as a 3vz / 5vz / 1mz, because they all share the same head designs)

i may have read that wrong, but how are you going to swap a 2jz-gte in a camry? i mean i know anything's possible, but no one is gonna take teh time to do that.
The meaning was to pull the springs/retainers/shim/buckets out of a 3s-gte or 2jz-ge/gte, OR buy their titanium aftermarket hardware.
(See the valve parts shoved in the carboard box? (the retaining hardware is under the blue tape so it doesn't get lost) We're talking about those.
Normally the RPM limit in a strong engine is determined by the valve-train speed. There is a good reason valve hardware always spins at half the speed the rest of the engine does.
The camshafts get to spinning so fast the valves stop following the lobes (i.e. the springs don't push against them hard enough), you snap a spring, or you simply throw the retainers that hold the spring down out.
Noone (i know of) makes new hardware for anything that is not normally a toyota racing engine. So you wind up swapping to other parts.

Yeah, besides the problem of trying to mount it transversally, there is much more information about the 1MZ-FE swap.
Good news, but wouldn't anyone wanting raise the rpm -> head limit just swap to 3s-gte, or 2jz-gte avalible hardware?

Actually no the springs and lifter buckets for a 5sfe, 3sgte, 2JZgte and pretty much any other head(except 4age) uses a wider spring and lifter bucket. For those engines you use the 1zzfe lifter buckets from an MR2 spyder. The 3sfe, 2vzfe and 4age all use thinner springs and lifter buckets and that is why it is jsut being found out that 1szfe lifter buckets will work in a 2vzfe and 3sfe.
Wow ok, good info then.
Jetspeed and army of one (if he keeps the other Lexus) need to pay attention to this LoL!

Wow thanks so much dude, this is fantastic info!!
So by having these lighter buckets..it alows the engine to..rev higher??? Is that the only improvement?
Keep more of this sorta info coming..its VERY useful..even if there istn too much following for the 2VZ around!!!!
Toysrme...your back??
