My question is which one should I get?

I have a B16a with Intake, header, and exhaust, and I just bought a skunk2 manifold, so I want to replace my throttle body while I was at it. I was woundering if they are like cams where tooo big is not good. Or should I just get the biggest I can find?

I eventually plan on doing B20/vtec, so would that matter which one I get? Does anyone have any experiences with good companies/products?

Oh yea, I also am running a mugen program.

 

As far as the throttle body, the inlet on the skunk2 intake manifold is 64mm and the stock b16a throttle body can be bored to 64mm. Here's a link to the guy that does it on here. https://honda-tech.com/zerothread?id=771875

And as far as cams, bigger is not better, especially when you don't have the compression to support those larger cams. Do a search for dynamic compression and that will answer your cam question. You'll make MORE cranking pressure on stock cams than you would if you had larger cams. You have to pick the cams based on your setup. And the larger cam you go, the more tuning you need to have done to get the best power out of them.

 

Yea, i understand the cam thing.

So... you would recomend 64mm for my throttle body? Nothing bigger right?

 

Ok, I get it... so a B16a JDM throttle body can only be bored to 62mm. Well, that what I got, so If I would buy a throttle body for a B16a2 del sol motor or something will the connectors be the same? Would it bolt right up... what application would?

 

skunk2 on d16 is only 62mm
