If you send me a block this is something I can do in about two weeks.

Actually no. I did a HR closed deck about 3 years ago and zero issues with heat. keep in mind the cylinder has water passages that only allow certain amount flow. The guards will have zero restrictions to the heads.

Chuck33079 03-05-2014 10:13 AM
So you don't block off any coolant passages with the guards? Sweet.

Wow. That's a fantastic price. A few follow on questions:
Are there coated bearings available?
Can you have the crank nitrided, or is it that way from the factory?
Would it help to send you the flywheel we're going to use so you can balance it together?

There are no bearings available other than OEM. They are the same ones that come in the GTR.

Crank is OEM however we drop it below -300 and up to +250 for 24hrs.

I have a OEM flywheel and balancer here at the shop.

Chuck33079 03-05-2014 10:58 AM
Nobody makes coated OEM bearings?

So we'd only need to send you a flywheel if we were planning on using an aftermarket one and we wanted everything balanced together?

Why is that?

Ron 03-05-2014 11:11 AM
I got an email from ACL saying that they have main bearings and thrust washer for the Z and GTR. No conrod bearings though.

Chuck33079 03-05-2014 11:12 AM
How the hell do they not have a full set if they're the same as the GTR?

Chuck33079 03-05-2014 11:13 AM
And can we just send a set of OEM bearings to Calico and get them coated?

Ron 03-05-2014 11:28 AM
Yes we can.

Ron 03-05-2014 11:30 AM
Part number is 4M2505H for the set of same sized bearings and 1M2505H for individual graded bearings. Thrust washer part number is 1T2505

Mr&Mrs 03-05-2014 11:34 AM
Man that's a great price!

Ron 03-05-2014 11:39 AM
I was told by several people to just run coated OEM instead... not sure why

Edit: Actually not several.. more like a couple of people.

Boss_302 03-05-2014 11:52 AM
Suggestions regarding the oil pump. That seems to be a weak issue with this engine.
Other than the NISMO race pump for $$$$, Any ideas on blue printing or upgrading internal rotor

I had a couple of my rifles "cryo'd" a few years back, makes the metal stronger and more heat resistant.

DIGItonium 03-05-2014 03:28 PM
I can think of a couple choices for our OEM crank bearings: coatings and shot peening. I might consider shot peening various engine parts. If possible, perhaps coat it as well.

There is a company here in Tampa that coats them. now for the draw back...You have to take in count the thickness of the coating. Nissan makes a dozen types of engine bearings. We have to order one of every size and test fit them in our blocks. Long process!!

Not a big FAN of ACL, considering they went out of business couple years back.

That's a lot of money in RND and pray to god we get it right!

We put the engine, Crank , bearings , rods and hardware into the cryo machine.

Ron 03-05-2014 06:49 PM
That's exactly what I heard about ACL.

MyKindaGuise 03-05-2014 07:35 PM
What a fantastic price. This looks really nice.

COSMO 03-05-2014 07:54 PM
Now that is customer service guys..

Bobby I will have those exhaust manifolds off this week and shipped down to you..

COSMO 03-05-2014 08:06 PM
Wow that is a Great price!!! I'm sure most are wondering why my cost was a lot more but it was due to going with a long block instead of a short block. To anyone interested I will be selling the heads, crank, timing cover/chain etc from my old motor.

09nismo498 03-05-2014 10:08 PM
Awesome price. I want.

TerribleONE 03-05-2014 10:30 PM
Killer price. I was thinking more in the 8k range. Subd

Yes you can I did this on my built engine it doesn't cost much at all.

At high power levels the 9:1 motor will see less stress than the 10:1 motor, but the 10:1 more will make more power for the amount of charge it gets.
Doesnt make much sense to me to run higher compression! I guess the next question here is what turbos are going to run on this build??

blackonorange 03-06-2014 02:01 AM
That's a disgusting price

Mr&Mrs 03-06-2014 06:49 AM
At this price I may say F the C7 for a couple more years now I'm doing a 180 again. Not to mention being local. Sigh decisions!

AdobePhil 03-06-2014 07:29 AM
Son of a bitch. I wish I knew about this before I paid Nissan 11 grand for an entirely new stock motor. Oh well. I'm sure I'll be happy with the turbo when I stop by later today and see her on the Dyno.

Wow I would never put a stock block back in a car. You can almost always go built for the same price or less.

ZKraken22 03-06-2014 07:43 AM
Any type of warranty on the shortblock?

AdobePhil 03-06-2014 07:44 AM
I learned my lesson. I was in panic mode. I blew it 4 days before I moved from Utah back down here. I tried to get it covered under warranty by reverting everything to stock but Nissan apparently has a little black box and denied me due to my AFR. By the time the Decision was made it was already 2 weeks without my car and Uhaul damaged it in addition during the move. So I just wanted to get it fixed because I was tired of driving a rental.

We cover our work, we balance and blueprint the engine. Chances of failure is very slim.

well it is still lower since the factory is 11:1 but as I said that ratio is best suited for use in the 550-750 range. anything more than that and you are going to want to go down to 9:1 for increased durability the dynamic CR at 10:1 and 17-18psi(700hp) is 12.5:1 that is the same as 20.5psi on a 9:1 motor
