Cusco Throttle Body?
 

Hey guys i was reading vivids blog today and found out cusco is planning a 2mm larger throttle body for the toyobarus. What do you guys think? This thing might be tits if the tuner can maximize its potential with the ecu!!

sounds great!

In my experience these are only worth it when you have the whole I/H/E and tune done. Im also curious to see some results

as in $1700 bucks worth?

2mm larger? Hand me my dremel and ill start doing it for forum members for 500 bucks :P

I would rather u do it the paying $1700, then again I don't have an extra $1700 in my pocket!

I wonder if there is a mistake in vivids listing or maybe there is a core exchange. $1700 is way to much for a throttle body hopefully John from @vividracing can chime in on this :party0030:.

I have to say some manufacturers are raping us and trying to get back their R&D costs very fast. Even a s2000 hks exhaust is cheaper than what it is for the toyobarus. Im glad AGP stayed real with their exhaust price. But if you look at kw v3's prices for other cars they are cheaper even if the other cars are more expensive. Looks to me like they are trying to get us back on their R&D costs :thumbdown:.

Even the Jun EVO X throttle body is cheaper at $1,300

At that price it better be made of unicorn tears and panda!!

For the WRX/STI their are companies that offer a porting service where they port the throttle body a few mm, than replace the blade with a bigger diameter one. I believe this service is $250, I can find the link when I get into the office.

In addition Skunk just released a 72mm DBW throttle body for STI I did some testing with. It looks very similar to the BRZ unit but I am not sure if it will swap over... This is big though and if it works, would probably only show gains on turbo cars... if at all.

It is a very very good idea tho the Vivids coming out with one tho, I'm glad

I wonder how large our throttle body is? I have already been thinking of replacing it with an RX8 throttle body depending on the size. The TC guys have been doing this too. It works you just have to open the TPS on it and swap it over.

Cool. Keep us posted on that. Good idea.

Will do

I don't know if that's such a good idea. I would be more inclined to buy this or have the stock one enlarged professionally.

2mm? for $1700...? You could get similar or better effects by half shafting the OEM piece and smoothing the inlet bump. Besides, I didn't measure it, but the stock unit looks fairly big for the motor. If no one else can come up with a number I'll measure mine after work.

The stock throttle is 3 inches or 76mm. I measured it when I made my intake pipe here http://www.ft86club.com/forums/showt...ighlight=chadz . Checking online the rx-8 tb is only 70mm. Also check Perrins blog http://blog.perrinperformance.com/2013-brz-exposed/ .

someone should make a +10mm over OEM throttle body.




;)

Q45 90mm would add like a bajillion horsepowers.

Doesn't seem to be a mistake. Circuit MS has it listed at $1707.

Haha rediculous. It's not even blue!

If you are replacing the TB might as well go big or go home.

Gentlemen that looks exactly like the lowly 2ZR 1.8l 220300T040 Toyota throttle body. If they're honing those out 2mm they're making serious bank. Hoping that's a stock photo.

Some people will buy it just because its in an available performance part and its Cusco, a ported one with a core exchange program where we don't have to send ours in to be modified would be cool if there are gains to be had.

It's a 3" throttle body already pretty large for a 2.0l car???

I think I'll wait, I don't want to have to explain why I spent that much on throttle body when the one for my Jeep only cost $200.

It is a bit spendy at $1700 for sure, but the one upside I guess is that it wouldn't take 58 weeks like JUN has been known to.

Here is the list of the new items to hit the Cusco lineup as well

Ignition Capacitor Kit
Grounding Kit
Big Throttle Body
Steering Wheels
Shift Knob
Final Gear Ring & Pinion
Close Gear Ratio Set

I'll check on the details for the TB for you guys and see what the situation is.

A lot of times the modded OEM is usually the best quality. When it comes to Hondas most of the top tuners just use OEM.

Only thing that cost make sense is the price.

76mm stock? For 200 HP? Wow. I remember making close to 300 HP in my old 5.0L mustang with a 70mm throttle body. Marketing an even larger throttle body sounds like snake oil to me, unless your going big boost.

This throttlebody seems about as useful as a one-legged man in an ass-kicking contest.

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?

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.

Yes.

So good :)

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
