Take a plastic cup. Now pretend that is you cylinder wall. If you try to move it like squeeze and stuff it moves easily. Now put the bottom half of the cup in cement. Everything flexes less. So it's just for support. I just went the extra step since I already cracked a block. Trevor is the only other person that I know of that has a 5S block half filled also.

My machinist does a ton of 4G63's. And he was telling me the rule for those blocks are, if you are running 40psi or more you need to to a 1/2 filled block or you'll crack it. And for 50+psi or the 1000+awhp they always do a fully filled block where coolant only goes through the head.

Looking forward to seeing how the cooling will be at normal cruising. 8) If i ever rebuild my engine to 1000+hp i guess i will have to do that to..

Fully filled is a drag race setup only. No more street driving with that.

For fun I ordered a oil pump from a 2001 Camry part #15100-74030

Here is a list of every vehicle that pump was in along with a price of $128.97:

I already had the ATS HV Oil Pump with a price of $169.00
http://www.atsracing.net/Parts/Details/E-OILPUMP

Please note I had already put my front seal in my ATS pump (it doesn't come with it). To me it looks like they buy the 5S pump and take the gear off it. Next grind the two spots where it says Toyota on it. Then sell it.

Sneaky buggers. You should post this over on mr2oc where they are vendors to see what they say.

Depends on where ATS buys them from. Their source might be the ones who grinds the Toyota off. It's not uncommon.

If you wanna see real difference in pump volumes, look at the gen 4 pump, that thing is super deep...

Cause I have already cracked a 5S crank. Didn't want to go nuts on it with a knife edge to have it crack again. if I crack another one I will be getting a Brian Crower Billet Crank.

Took out my rear Factory LSD today to replace it with my new Cusco. I bought the diff brand new from Toyota, but now I have been hearing that people at my power level break the stock one. So I now have a factory rear LSD for sale that has about 2,000 miles on it. lol

Anyway took it out and put the new Cusco in. Monday I'll take it by my buddy who is a tech at Toyota to check back lash, bearing preload, and how the gears mesh. Once that is all in spec I'm going to completely disassemble it again to have it sand blasted to prep it for power coating. Hopefully it will be bolted back into the car in about 2 weeks.

Diff housing pulled out of the car:

Just opened it up and pulled the bearing caps to looked for the c clip for the axles. Only to learn the LSD is like the front axles, They have a snap ring so they just "pop" in. So with a little fineness with a hammer we got the axle ends out:

Diff pulled out:

Cusco left vs stock right:

You can see the clutch discs of the Cusco:

Cusco installed:

Black. My buddy sand blasts it at his work. Then his neighbor tapes it off and coats it at his work. He does industrial stuff so I only have 2 options. Black or Wrinkle Black. If I want colors I have to go to a normal place.

Here is the case blasted:

And the Trans case with wrinkle black powder coating:
