Since Brent has already posted on it....here is the cliff notes version of it, and Brent can chime in if he wishes.
Engine was built and tuned at AAM and arrived at our shop overheating and shooting coolant everywhere.
We tore it down and discovered the blown head gasket, and discovered crooked stud with 1/16th inch runout. Brent had a ralley to attend, and he made the decision to do an in-house fix of the gasket. Normally, in this situation, we'd recommend sending the block out, and having the whole thing replaced, and new studs installed. At the time, that was not an option since Brent had to get back on the road quickly. We did everything possible to get his car running within 2 days, but all along, we both knew there were risks involved with this approach.
Tuning went really well, and the car made strong power, but still less than I expected. I kept Brent informed all the way through this process.
Sooooooo we thought we were out of the woods. 666whp on my dyno 742whp on the dynojet, and no overheating or anything else.
We let the car sit for a week or so, then fired it up. Immediately, I could tell it was missing a cylinder, and then it overheated while idling.
Compression check uncovered very low compression in cylinder #1. This was the cylinder with the crooked STUD!! Our fix held for dyno tuning, but the cool down properly shifted something slightly around the stud, and that was that.Julian, Darton sleeves cannot physically sink. If you look at how they are designed, machined, and installed they are completly different from AEBS sleeves. Sinking is not possible, unless your entire block cracks. I am too tired to explain why.
Goodnight.

I do know this, Brent posted in the Mid-A forums he was thinking about selling, that would be a huge shame considering the time, $$$$, effort he's put into that car. Im sure he'll chime in soon enough.....
wtf no turbo-this has nothing to do with the power level (over 500whp) it has to do with quality control of a machine shop and the shop in question. Brent's motor was more than capable of handling these power levels if everything had been done correctly from the start, he doesnt skimp on things.

.Got it recharged and its been fine since. i dont drive my Z every day but I have fun with it any time I can. Ive gotten over 2000 miles on it since the build and it runs just as smooth as day one. So for almost two months the Z has been good to me. And sorry to hear about your car Bam Bam. I remember when I picked mine up they were talking about how hard they were working with it.

I spoke with Brent on Monday and he is really bummed out about this but realizes it was a gamble. It just seems like the whole engine build was a cluster f##k and was poorly supervised/managed by AAM.

I wouldnt put blame on Brent or Forged for this they simply made the best of what they were given. Im sure if the stud/head had been reworked the car would run strong for a long time with Sharif's nasty tune
-well the motor at least, then you gotta worry about other things. My motor like the guy above also did 541whp on Sharif's dyno (580whp on Dynojet), and Ive had zero issues with it, my tranny on the other hand that was my bad
-----> you pay to play....

Audible, we checked the head and block in about 50 different spots, and it was perfectly flat....less than .001 with spec being .004. The block and head were straight after we took it apart. I am not sure where the sleeves where installed, but there was no sinking or issue with the sleeve.
The issue was the crooked stud. And let me tell you....it was a biatch to get the head off his block when we tore it down, due to the run out on the stud.
In regards to reliabilty, we have done a half dozen builds at about the 600whp DJ range....and many more more mainstream power levels. All running very strong after thousands of miles. The only reason this engine failed, was the stud, IMPO.
Alberto summed it up nicely. Hindsight is 20/20. The most disspointing thing about this whole episode, is that we thought we were 100% out of the woods.

I am humbled every single day....I am here at least 14hr/day. I work with some of the best technicians in the business, terrific suppliers, and GREAT customers. Working on the 350Z is a total passion of mine, and it kicks us in the butt from time to time. You cant get complacent in this business. Nobody is perfect.
And what is the Blue Oyster?

Also I was unaware of the type of sleeves he used, but anytime you sleeve a block you do loose integrity of the block itself..And it does prone the block to flex and possibly warp...Performance Motorsports was actually experiencing this on their street tire car, in the motormount area, until they resolved the cause, which will rear its ugly head at the 800whp mark
I too share a passion for the 350Z and I hate to see anyone have this happen to them, especially twice..But like you said, sometimes these things happen... Perhaps in the future you could be a bit less hostile towards me, since I do detect a slight bit of hostility towards me in the past few weeks, and I myself am growing agitated at it.. We all have our off days, but please do not disrespect me again on the boards, when I am just giving some insight..
I honestly hope Everthing works out for BAM BAM, as he has been through a tough time with this car...And I would like to see him stick with it and not give up on the build, Im sure the stud can be fixed..

would everyone quit being ****...making a 245rwhp car into a 800rwhp beast isnt easy and will have its trouble, i have learned this from building my old intgera 6 times, it sucks that this happend to bam bam, but the 350z was never meant to put out this kind of power, and unlike a honda, these parts cost a grip load of money. I have a bunch of friends in the 600+ club and they all went through a few engines (built), this car is still uncharted territory, 500 IMO is safe and can be driven all day, wanna go past that...well get ready for issues. MRC and Sharif do great work, but were trying to make 3-4 times the normal stock HP, shlt happends...and im not trying to be rude, but your going full race, and full hardcore...problems arrive.
