What TB would be the best option for a 350 hp engine ?

Like to have a nice upgrade to keep as much low end power
without sacrificing the top end power as well.

The factory tb is your best option. Anything larger will only reduce throttle response. No point in upgrading it for such a low power range.

When do you need a upgraded TB....400 mark?

You'll know when you need to replace it with something bigger.

Well...Its funny you say that because after my winter build, I think that I will need a bigger TB. =]

I should be putting down 550rwhp and I'm running a factory 1J TB which is the same diameter inlet as the 7M's. I'm more concerned about throttle response then losing a little up top. Unless you're upping your IC pipes to 3" and going stand-alone, I woudn't mess with the TB.
