According to what bluefish posted about 2 weeks ago, they can. So unless they swapped in a motor with aftermarket sleeves...

If im not high, Andrew Rubio is the driver for Smithtown Nissan and a 161 mph trapspeed on a ruffly 3200lb car is just over 1000 to the wheels.

I think Modified Magazine has an article on Smithtown Nissan. Im gonna go pick one up. Man do i hope thsoe are the stock sleeves.

 

if they can, it isn't for long...

 

I couldnt wait. I started reading through the article at the supermarket. As far as internal work, they are using JE forged 10.3 pistons (that 10.3 might be a typo), Carillo rods, ARP head and main studs, and valve job/exhaust porting. As far as drivetrain, they only mentioned a NISMO LSD and finned pumpkin. They are also using a TEIN Flex w/ EDFC, 15x9 rear aluminum wheels w/ BFG 275/50/15 DRs in the rear, and 15x3.5 skinnies w/26x5-15 Mickey Thompson front runners.

 

Kyle at SGP posted that there are 700-800 rwhp 350Zs tracking in Japan. He hasnt found one yet that has failed due to the sleeves walking or cracking.

Ive looked at my block and noticed something alot of pics dont easily reveal. The water jackets are not very deep at all, they are maybe 3 or 3.5 inches from the top of the sleeve, or the heads when sealed. While making alot of power, it would still be hard for me to imagine a stock sleeve cracking from normal combustion, because the piston would be under the same stresses as the cylinder walls and they are about 1 inch thick forged aluminum. IMO, the most likely method to crack/walk these sleeves would be to over heat the engine to the point where the aluminum holding the cast iron sleeves begine to expand faster then the iron sleeves. And since the hottest part of the cylinder is at the top, the head gaskets might blow before the sleeves give. This is all just my 2 cents.

 

what kind of turbo's do they run ? The 10.3 pistons must be a typo....8.3 to1 would be my guess

 

or 9.3:1.... That's what I am geting incidentally.

 

It was a Power Enterprise Twin Turbo. Ya I think it might be a typo. I bought the magazine off the counter just to read about it. In the earlier edition, they had an article about the Greddy TT for the Z.

 

No...it is probably 10.3:1. Most of the high Hp honda's and other turbo race cars run >10:1 compression. Remember this is a drag car that will only see race gas

Oh....and yeah I don't doubt that the stock sleeves could handle 1000 Rwhp. They are not as open deck as people assume.

 

I was thinking that too. I doubt the PE kit could raise their effective compression ratio high enough on 3.5 liters and 8000 rpms w/ low comp pistons to make 1000 rwhp.

Hey Kyle, have you ever considered machineing a hair line off the top of the AL block so that the sleeves would fit up tighter to the heads? Im talking like 0.001 inches.

 

The car is not making 1000 hp to the wheels on a PE kit. The car in its current form uses Turbonetics turbos to generate the current high hp. I forget what the peak hp they made with the PE..I want to say high 500's but I don't recall specifically

 

Thanx for the clarification.

Look at rnd 3!!!

"3 Andrew Rubio Nissan 350Z 8.640 169.38"
Thats ~1200 rwhp on a 3200lb car!!! Smithstown Nissan is within 3 mph of 1st place if they can put the power to the ground.

 

Look a little closer. He actually managed to achieve 8.640 and 169.38mph in a later bracket... Damned those Supras..

 

Whoops, you'd already noticed.. my bad (hides)

 

LOL...

 

I wonder what those 2 new holes are for?

 

Yes, without a shred of doubt. They CAN, and WILL. As will your crank. All you need to have a bulletproof VQ35DE bottom end is good rods and pistons.

 

Darton Sleeves, they now have MID sleeves for 350Z. Bore, 95mm(VQ35DE) - 100mm(max).

 

Those arent a very good design.

 

you think that car really weighs 3200lb? it might... but i would not understand the point of building a drag purpose car and not doing any weight reduction....

what do they run for intake manifold on that thing?

 

honestly... i regret having the sleeves done to my new block.

stock sleeves seem to be just fine for power and with my sleeve job done I am nothing but paranoid about them sinking or something. too many horror stories in the honda world i come from... and to have a problem like that in a 350z is not a small problem... this is not the car i want to have to pull the motor out of multiple times over some ********.

i should have kept stock sleeves.
