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??

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

Hi ...
Following this build out of necessity... :-(

Just want to clarify things in my mind ...
I need to rebuild my motor.

I have stock block with an upgraded Stillen SC'r making 11.9 lbs boost along with 1000 lph injectors and other supporting goodies.
It dyno'd at 483whp and 378 tq.
First time down the track it cracked a piston or ??? Nothing came thru the side of the block.

Would like to keep as much of the mods already done but keep or up the power to the 550-600 range while keeping the reliability of the motor.

Definitely a Long Block (can send my motor) - but need advice / recommendation for the Compression Ratio ~ Pistons and Rods

9.0:1 or 10.0:1 ??? for the Supercharged motor.

All help greatly appreciated !

Many Thanks,

I never understood why the price can't be out in the open. Why send a private pm?

blackonorange · 03-04-2014, 11:57 PM

^ yea I'm not sure why. I guess to some ppl it's too personal

Some people get better prices by being smooth talkers.

Or by giving back alley handies....I like to try and smooth talk.....first....

No smooth talk....just the handy...just don't look into my eye's.

To make a estimate I need more info from you guys.

1) Rebuild your current engine?
2) New bare block from Nissan?
3) Does everyone want the same CP Pistons
4) K1 Rods?
5) Cryo treatment?
6) L19's
7) Balance?
8) Build a short Block? Or long Block
9) Are you shipping the car down for the install

Building estimates are very time consuming and each and every one of you could want something different. I post up some prices for a brand new short block.

plus if we do a group buy, you guys will receive a better price on the pistons and rods.

I look forward to building all you guys a engine
Thanks
Bobby

Like I said before, no interest on a group buy. I would hope you would be open to selling me a built short block without the group buy. I was hoping to get a quote to recreate Cosmo's build with a fresh block, and also if I shipped you my block.

Ok, will do. can you PM me your email address? I will shoot you over a estimate.

Mr&Mrs · 03-05-2014, 08:52 AM

Since I am local I would just let you use my current block. I like cosmos build as well. Almost forgot any alleys near the new shop? I haven't made it out to it yet.

hahahahahahahahah

SRperformance · 03-05-2014, 09:39 AM

By the way how soon are you guys looking to do a build?

Chuck33079 · 03-05-2014, 09:41 AM

No time soon for me. I just want a number in mind if I ever need to do it.

Chuck33079 · 03-05-2014, 10:05 AM

Doesn't the Z run hot anyway? How much more heat are we going to be dealing with on a closed deck block?
