I have a ls vtec turbo and i recently spun a bearing DUE TO USING RACE BEARINGS. O well its not really a big deal. Now my question is on my setup

Ls bottom end:

Scat H beam Rods w/ arp rod bolts
Mahle 9:1 compression pistons
oem main bearings
oem rod bearings
Arp headstuds
oem headgasket modified for ls vtec
b16 vtec oil pump
b16 vtec water pump
fadanza 7.5 lb flywheel
unorthadox racing crank pulley

all mated to a b16 head with

STOCK VALVETRAIN
aebs intake manifold
Hayame fuel rail
Hayame fuel pressure regualtor and modifier
but pretty much a stock head

Now this car will be turbo pushing around 400-450 at the wheels but i will be only revving to about 8500 due to my stock valve train....so if im only revving to 8500 is it worth it to take the ls crank...send it out and get balanced? All feedback is appreciated.

 

I would if it was my motor and i just invested all that money it. Especially if you are going to be revving that high with it. If its not balanced even the slightest wieght thats out of place at that speed could cause serious problems.

 

I wouldn't worry much about it as they are blue printed and balanced from the factory.

Now if you do have the funds to do it, go for it. It's just another ease at mind.
But if your strapped for cash, it's not something that I would worry about

 

yea...bump for more feedback....im still in the thinking process here of weather to do it or not.

 

I would recommand you doing it. If i remember it right it is not that expensive at the machine shop.
