Best shop for Built Motor?

ACTUALLY, you will be in much greater danger of oil starvation and spinning a bearing if you are revving higher/more heat/more power with tighter clearances...
notice in my explanation, my LAST point was "they will make a bit more power"... this is NOT the reason to run larger clearances, but engine longevity is...
we have seen several stock engines have spun bearings on several journals when they are finally opened up due to say, a piston failure...
to keep a forced inducted daily driven street car, that is going to be producing 2-3 times more power than intended from the factory, it is foolish to run stock clearances, spinning a bearing is more common than a engine "wearing out" prematurely from larger oil clearances

especially since many are revving these engines higher than intended as well! lack of oil to critical areas due to tihght clearances is MUCH riskier..a worser evil...than larger clearances and risk of premature bearing wear (lesser evil)
If you want the "BEST" Motor build then go with a GTM Motor. I'm sure they have distributors that are local or close to you, like MRC or so? Sam at GTM has been racing and building engines way before most of us on this forum were even born. He has true racing experience and has millions of dollars of machinery that is precise to the tee. His quality control is hands down the most detailed I have ever seen. I could start a whole thread about this but you said you wanted the best right, nobody comes close.

I think most distributers have been using resources that have been in this industry for many many years, no question about it....anyone in or around the California area, without a doubt, go to GTM for the entire package, engine build, install , and tune, would be silly not to!!!
PS: Sam has not been racing before we were born, he was in 2nd grade when I was born
, he's still a young vibrant entrepeneur! -TODD

not running forced induction, lower CR pistons, 87 is fine.. the motor was built to remedy a freak stock rev up motor catastrophe, he wanted to be prepared for FI this coming year

You Obviously haven't seen Sam's ultrasound images when he was in his mom's stomach?

no its not fine.. sure it maybe ok for the motor that it won't detonate.. but you are messing with sensors and electronics that shouldn't be compensating for such low octane
it'll be fine...really...he's not running leaded fuel, you are funny...oooooh the sky is falling!!!! oooooh...
...not ideal, but i bet your bullocks to a barndance he'll be fine

If i was in mexico running some 81 octane leaded fuel i would worry. But im not getting in a pissing match about octane vs compression. And doug if you understood and did some research on how the stock ecu works you can run 87 in a stock Z. I used 87 in a 3.5vq altima for 3 years, it never blew up. Your probably one of those people who would run 93 octane in a stock low compression car if you could because its "better for your engine" when all your doing is wasting money.

Even I know that you should never put 87 octane in a 350z (read the label on the fuel door) this is very bad coming from an engine builder (or should iI say Chiropractor)

What happens when you lower the compression? That's right, the risk of detonation decreases.

the 2007 Maxima has high compression.. and the manual/door says 87 octane..
You do know the stock ECU has fuel and ignition maps for lower octane? Besides the label on my fuel door no longer applys, its not a factory engine, and i have a utec, datalog shows no knock.

Exactly... to me its about being a "professional" engine builder. To say "Oh its low compression so there is room for error" Its like a dentist saying only brush your teeth once a day, sure you can get away with brushing once a day but the risks of cavity and other mouth diseases may arise. But again, this is what separates true professionals from amateurs.
