and about the durability issue?

 

depends, are you racing this motor all the time? High reving it every day? If it is a race motor titanium valve retainers usually get replaced when you rebuild... But for your use, they will be nice and light.

 

Do you think this set of HC pistons brings the rings?

is all the kit?

 

not sure, call them...

If not they should only be around $65 for a set of rings.

 

Okay, here is a complete racing build up (IF the pistons bring the rings), and this is for N/A setups...
And the cost is....TAN TAN TAAAAAN!!!









without S&H: $1,306.97

 

Here is my list of those mods:

MAIN BEARINGS:TOYOTA/SCION 2AZ-FE (SET)
ROD BEARING:TOYOTA SCION 2AZ-FE (SET)
SCION TC COMP PLUS VALVE:29mm/EX (EA)

Care to compare prices???

I did already, and a Port and Polish done locally and all those parts are way under the price of getting the things from ZPI.

 

your reasurch is aawsome. what parts are availablr for the bottom end?

 

Okay, what parts are available for the bottom end? What I researched was about the same parts that are available for the head and also our piston options for us. Looking at the Stage 2 Head from ZPI and its components but also taking into this the Main bearings and the Rod bearings, the price would be over the ZPI Stage 2 head, but with those last 2, the price (in ZPIs website) would go over mine by a lot, get my meaning?

 

rods and pistons are out and of course bearings. ARP bolts are also availab.e. Everything is out there now to make a bullet proof bottom end

 

For a N/A setup below 300whp I think the stock rods will be okay, I'm not building the super All Motor 2AZ engine. I'm keeping it below that so it can be more reliable.

 

for NA motor, I would go with some higher compression pistons. That's about it. JE Pistons has 11.0:1 available.

 

I already thougth so.
