I would say if you got the cash do it now and be done. Doing it later just mean more money and down time. Just my two cent.

The bad part comes if you pop the motor. The old one is junk. So, one low mileage junk yard long block for 2 to 3k. It is best to swap out all of your electronics to said motor after it is built. Two turbo rebuilds for good measure just in case metal shrapnel made it to them. CAC cleaning. It will be 7 to 10k more expensive if that happens. Sometimes, that is the game we play and the risks we take.

Yup, you pretty much nailed it!

While you're at it. Bigger throttle bodies.

With an FI engine I think they are a waste of money. A goal of over 1k hp, then yeah. When you get to that point, maximum boost becomes an issue so you are trying to find ways to reduce the restriction, hence reduces the max psi of boost. That is where the learning curve is at now days with several folks over 800hp. Good luck to them.

Does anyone know when you need to swap out the crank to a Bryant racing Forged crank? That level has got to be somewhere between 800 to 900hp.

Why not just buy a BC kit that is rated 1000 whp++?

That Bryant Racing crank would snap the BC kit in half without much effort. Those cranks will spin to the moon and hold all the power you could throw at it. Hence why they cost upwards of $5000

Because a BC kit is not good enough for me. Bryant cranks are expensive because they work.

I believe Doran Racing was using Bryant cranks in their race motors.

Yes, with a dry sump setup.

MaMotorsports told me anything over 800whp. I went to the shop to put a down payment on a BR billet crank.

I called Bryant Racing yesterday and the guy I talked to didn't no chit. I asked him about a crank for a vq34 and he had no idea what I was talking about he said they had ones available for vq35 and vq37. He said the cost was around $3k.

I think if you are wanting to rev 8k or above for more than a quarter mile run you need to upgrade your crank. If you are going to run on the street, I don't know if a crank upgrade is really all that necessary. From what I have seen of all the plus 900whp builds, many other things fail before you get to the crank being a limiting factor. The number issue has been extreme heat and the upper manifold failing at or over 22 to 23 psi.
