Cusco Throttle Body? - Page 3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

The factory throttle body @ 3" is huge for the displacement of this engine. It's more than sufficient. The issue that needs to get around is how these things are choked up by 3 catalytic converters.

Hey Guys, figured I would help answer some questions.

There is no core exchange required - it's a complete brand new unit. It works with the factory ECU and it requires no additional tuning or modifications.

I have 3 coming in next week. PM me if you want to get one ordered.

I'm not an expert at the engineering dynamics of throttle bodies but I am a consumer who does a lot of research for the products I buy. I did a fair amount of research when looking to upgrade the throttle body on my 97 m3 (3.2l inline 6) and the percentage of the increase in area was one important aspect. I realize that comparing engines is rather pointless but i wanted to point out the following:

FRS

stock - 76mm
cusco - 78mm

Increase of 2.6%

M3

stock - 63.83mm
Dinan - 66mm +6.46%
Riot Racing - 68mm +11.9%

There are other aspects to BBTB such as smoothness of the chamber and the single vs. dual arm. However an increase of 2.6% makes the part seem more of a bragging right rather than a performance part.

Maybe some of the tuners who having been working with the FRS can tell us if there is any need for a larger throttle body or at what power/modifications point more flow is needed.

If the stock throttle body's O.D. Is 76mm I don't think cusco will make it bigger from the outside. I bet will be the inside instead. Anyone know what's the stock I.D. Of the TB ?

If no one knows, I will pull my TB this weekend and check !

Best answer.

76mm is the stock Internal Diameter.

Just curious what kind of gains can be expected from this?

wparsons · 10-23-2012, 08:35 AM

Is it actually 76mm at the throttle plate, or is that the I.D. at the tip of the inlet?? Most 2L engines run WAY smaller TB's than this. Typically 70mm is a huge TB on a 2L.

But Cusco.. it has to be better?

What about if i put a HKS sticker on it? would you pay $2250?

I think my post is about as pointless as this product..

Sorry.

I sprung for a Dinan OTB for my m3, but it was part of a tuned kit, cai package and software to match it all. The OTB from cusco by itself for that money...pass

FRS-HHH · 10-23-2012, 09:55 PM

i heard it was made using Chuck Norris's tears

must be good then

Measured the TB here. Mostly approximately, but not bad at all.
