if it makes you feel any better, I just destroyed my bearings (knock) in my built block

Sorry to hear that. Did you buy bad gas somewhere or what? I can tell you when I get mine back I will not be running mine when the heat index is 110 degrees....

What is the typical, and your, cause of spun bearings in these motors? I am going built and am using OEM bearings since they are really all we have to use. Is it pre-det that is the cause?

as long as assembly is handled properly, which it was in my case, it's knock. I would suggest getting the bearings coated by calico, really effective against wear

To be honest I starting to think I should have just stayed stock..

I was feeling the same way when my Stillen build started to run way over what I had planned as far as time and money but it was well worth it when it was done, then felt that way AGAIN when I blew my motor due to my own idiocy.

But now going back together with a new built block it's so well worth it again, you'll get that feeling back once you get over the humps.

I'm in the same situation as you are ... I'm on "Build (Again) #2" - but this time starting off with a built motor...
Got pretty bummed when the motor blew after the 1st build, trying to eek out more performance from the Stillen kit.

The Stillen kit worked pretty good until I got that itchin' for more speed at the track.

I'm working on putting up a thread/post detailing the trials and tribulations I've had to face and overcome along the way.
It is kind of funny in a way tho'

sorry to hear all the bad news
if i could do it all over again i would not have gotten in as deep as i did
i can say stillen supercharger then vsr turbo and built motor and all the little stuff in between is 25k easy

and atm 2 little sensors are still stopping me from hitting the 600+ mark
and i keep thinking price of the car + 25k in mods = used gtr lol

honestly, if you cant be happy with ~500-550whp, its a money pit and you should walk away unless youre willing to keep spending money on it. the best approach for our car is low boost (8-12psi), stock block, conservative tune from a good tuner(use e85 if you can). I say stock block because its proven to handle the hp/torque (despite what people claim are the limits) and its far less likely to have issues that built engines can have if not done properly.

Since you're already built, I would simply advise against turning up the boost too much and hope they're good at what they do despite the rear main seal. Find the best tuner you can, make sure they use knock ears when turning up the boost and keep it safe.

I still just can't believe they missed something so small and now it's causing even more time and money to be fixed.. I can promise that if there is anything else that goes wrong on their end they better be ready to settle on an amount or fork out for a good lawyer... I'm skeptical even at the thought of my car being in anyone else's hands besides my own since there have so many mistakes on their part since this all began. Trust me it makes me sick to my stomach thinking about this situation everyday...

COSMO

Good at what they do is yet to be seen!!! lol I spared no expense on the internal parts in hopes this would remedy any future issues but like you said How good are they. That seems to be the question at hand here. Only time will tell and if not w will be going to court and it wont be just for the cost of my built motor.

valpozguy

Tell me more about this KandN filter deal? What adverse effects?

I'm guessing that's w.r.t. over oiling and the oil messing up the MAF
