Streetzlegend goes to the darkside (3.5!)
Another project for next winter...
I saw one '06 350Z engine for sale on ebay - it had a bent rod when taken apart, and the motor later turned out to be a factory core return that had been in a flood - one cylinder might have been full of water when the engine was turned over. I know this because I bought the heads from the seller after no one wanted to buy the entire motor with a bent rod. One of the heads had a "Flood Damage" label on it. Got 'em cheap, too....

Man that stinks, I hope you get it all figured out man. It just seems like bad luck these last few months for you motor wise. You need a bulletproof motor so good luck with whatever build you decide to do, we all will be in for results.
Carrillos for me - same reason - puny stock rods - I can't believe my stock rods are still holding up under a 175-shot...
sorry to hear that streets. I think im going to go with eagle rods too, ARP,head studs & rod bolts and cosworth Head gaskets. Think thatll be ok for 400-500hp or i might need some lower compression pistons? if so what would be ok? 11:1 Wiseco pistons or i need to go lower to a 8:8 Wiseco or 8:5 JE pistons?
Dont mean to thread jack in anyway streetz

ea, im new to it too. havent gone further then cams when it comes to internals. But thats my same understanding, lower compression= less chance of detonation. I was just didnt know if 8:? was too low/unnecessary. I want to get this other 3.5 in and with stronger internals and boost by mid april.
From BoomBop - $1,200....
but that's all six pistons and the coatings,pins/rings/options together.... the bearings were - extra - from Cosworth... You don't want to know about the Carr fastener Carrillo H-beam rods. But this should make a nice short block for summer.

Crap, your going for 1,000hp then lol.
Na, I'd blow the engine for sure... Rods, pistons, bearings are rated for 1,500HP actually, which just means the short block will be tough enough for a huge spray job.
Add the Cosworth CNC ported heads with big valves and their ZK2 cams, and this puppy is gonna breathe !!! N/A HP should go up 20% or so, then three nitrous stages under computer control - that also shifts the VLSD - with VP Racing 109 race fuel, and, well, if it blows up, you could see the fireball in Florida.
I've just been out this week with the present 2002 3.5 with the updated fuel system set for 405 WHP and it's a beast again - if the rains let up, I'm going to KCIR this Saturday and let 'er eat!
I think the new engine will dyno at 500 WHP after break-in - then we shall see. Oops - I got excited again - you're the one that needs to get a RMT turboed 3.5 back on the roads.

AND IM COMING FOR ALL OF Jo0o!!!!!!!!!!!!!!!!!!
just ordered the Eagle connecting rods with ARP 2000 rod bolts, ARP L19 Head bolts, ARP main bolts, Cosworth headgaskets and gasket matching my exhaust and intake ports. Decided to stay with the stock compression pistons because they should hold up to my goals 400-550hp via my gathered info from my350z.com.
FYI, ALOT of good info on there about what 3.5s can hold and peoples expriences such as cosmic gaskets being ka-ka, and RC injectors staying open and Wiseco pistons being iffy.

well, i was referring to the gaskets once mixed with 300+ hp.. not doubting your belief in them, just from what ive been reading.. they dont like boost or heat too much more then stock gaskets
My gaskets are mixed with 300+hp(stock ecu) so I def belive in them. I frequent my 350z and I take most of the info with a grain of salt. Dont get me wrong there is a lot of usefull info on there but most of the time products/setups/engines fail due to poor/inproper installation/tuning.

Some have made crazy power on a "stock block" with "oem" parts. In my opinoin I would at least install standard arp studs while your in there (personal preference) L19's are considered "overkill" for your goals(550hp) but My best advice is to build your car to your likings.
Since everybody else his high jacking streetz' thread, I might as well. 
First off, way to make quick progress Streetz! You've never been a person to just sit around thinking about stuff. I bet you are going to have TWO engine swaps and builds done in your car before it takes me to finish my ONE engine swap project. lol
But, what does everyone think about thicker head gaskets? The stock VQ35DE and VQ35HR head gasket measure .024" compressed. Is there a reliable head gasket out there that is as good as or better than OEM HR with a compressed thickness of around .030"?
I would really like to go with a VQ35HR head gasket simply b/c of the better cooling passages. But, I may have to use a thicker HG since my machinist removed a tad too much material from my heads.
Thanks.

Im not trying to thread jack I just figured this is on topic somewhat...lol From what I saw in your thread you are .001" over the limit. In my opinion any one of the gaskets should set you back within spec.

I wonder how hard it would be to remove material from a aftermarket hg to fit as a hr gasket?(for your cooling preference)

Part Number Make Application Gasket Type Bore (mm) Compression Ration Thickness (mm)
23001-AN002 Nissan/Infiniti G35/350z VQ35DE motor * include right and left gasket* Stopper 97 10.3 0.7
I THINK this is .0285 " ?? and they're not cheap.... $318.00

Guys I dont mind the thread hijacking as long as its on topic, this is very useful information for my build and for others in the future, so keep it going. I need to pick a head gasket now, so I also gotta do some researching, I might lead more towards HR perhaps, just gotta make sure what exacly needs to be modified or ported (gotta check out the JWT site, they have info on making it work), Yea aaron, i dont like waiting around, i just get things done lol.
I just placed an order for Wiseco 8.8:1 96mm pistons!! looks like probably end of this week or starting next im goin to have block bored out, balanced, and ready to go! i say within less than a month im back on the road. Now my next purchase is bearings, and head gasket.
