Anyone use Summits 103mm TB on their FI setup? A little cheaper than NW...

Got to wonder how much power you are trying to make if you need a 103 on an FI setup. Nobody in the FI forum really needs a TB that big, although somebody may have one. Just a thought.

DBW TB’s aren’t something I’d skimp on. They’re a big enough pain in the *** as is. I’d gladly pay an extra $70 for a proven one. That’s not to say I have any direct experience with the summit one….

As an FYI. Our 92mm and 102mm drive-by-cable throttle bodies are currently made in China. However, our 103mm drive-by-wire throttle bodies are currently made in the USA.

I disagree. A centri or turbo no its not really worth it.

On a PDS, hell yes.

Magnuson Sc'd fully forged LSX bored 4.125 hoping to hit 800+

I'm actually gonna try for 1k on the dyno even if we have to spray a little but then it will be dialed down...

I stand corrected. I was thinking turbocharged for some reason.

No worries and I wish turbo lol, just working with what I have and making it better than how it was. Long story short, previous owner, that passed, got ripped off by some shop in FL with actual build and tune...

We don't see a Holley or Holley Sniper 108mm throttle body. Were you referring to the Holley 105mm throttle bodies? If so, those are currently manufactured in the United States.

Same here. My mind just instantly went to a blow through TB. Obviously a PD blower will be an entirely different story. My apologies to the OP for the misunderstanding.
