Anyone using a JG Throttle body 65MM?
Are they any good. Some people say no good, some say it's great.
Some say it's not a good upgrade for mid range.

What's the truth? Is 65MM a bad size for my GS-R with stock insides.
Port match IM or not?
I'm keeping my GS-R IM. I'm looking for midrange and low end power. Don't care for high end.

What are your opinions on this?
What are you using.

 

Bleh! I say get Erick's racing 72-70mm (tappered 2mm) TB. lol

Proper TB Size is determined by how your IM is set up.

The plenum volume is critical on N/A engines, and a basic rule of thumb is: The smaller the plenum, the lower the rpm range, and bigger means higher rpm. The throttle body size and flow rate also affect the plenum size: Bigger TB, smaller plenum, small TB, larger plenum.

bigger is not always better, an ITR taper bore TB (70mm at the intake side, and 65mm at the plate side) is more than enough for heavy b18 NA buildups.

I did not understand what he was talking about can someone please explain this.
Thanks

basicly leave it stock unless you have a different intake manifold

 

I see. So if I port match then there is still no advantage to it. So unless I get a Skunk or some other IM there is no point.

Along with better internals.

I (stupidly) ran a 70MM on my stock B18C1 with AEM CAI and exhuast. I finally took it off after I realized it was hurting performance, and pointless.

 

I had my stock TB bored to 64mm by Leitner Performance. It mates with my skunk2 intake manifold quite nicely. They did an excellent job, and had a great turn around time. It ended up costing me around $140. Not too shabby if you ask me.

 

unless you have cams and good intake manifold and free flowing exhaust sytsem. you can spend you money in other places with better results

 

The Spoon TB is 1 of the best in my opinion!! It starts @ 70mm than tappers down to 65 which gives you good throttle response and there is no need for the port matching BS!!

 

anyway to get a spoon TB to fit a GS-R?? I had a problem with the throttle cable bracket and placement of it. It spoon 70 to 62MM?

 

you don't want another TB at this point.

Your TB has to be mated with the charectorisitics of your IM, (long vs short runners, plenum, etc).

Just buying random parts and putting them on is going to waste your money and hurt performance.

Thats all good in a fantasy world but when you dont have all the cash to get all the mods you want working step by step is just as good but as long as you have a plan on the all the mods you want!!

This answer for the Spoon TB what you have to do is switch out the throttle bracket for your GSR to you Spoon TB and it should be good to go!!

It has nothing to do with a fantasy world, step by step is fine but also consider which is a more reasonable place to go first.

Just buying a random TB because someone said "Spoon YO!" is going to be a waste of money when you find out that doesn't fit your engine package.

If you already have i/h/e, get a highflow cat with matching diameter. If you want to move on from there, look into internals (cams, high comp pistons) or tuning tools. Cam gears, AFC, FPR, all will get more HP out of a mild bolton B18, I have seen dyno sheets to prove it.

Dude if you would of spent the time to seriously read my post i said that when go step by step you need a beginning and a end plan!! If you did you Homework on all the products you wanted before you bought them 1 by 1 there is no excuse to find out later that this part is not good for setup!! Just do alot of research of all the products you are intrested and just stick with the plan!!

Personally though the SPOON TB is 1 of the the best TB out there and if this thread gives you more info on this product then my posts have helped you out with your decision!!

 

I have read your thread, I still disagree.

Even if you have planned out your entire engine package, why would you buy and install a part that is going to decrease your performance till you get the rest when you can buy and install parts that increase your performance in the mean time.

If you were going supercharger, would the first thing you bought be a large primary 4-1 kamikazee header and 2.5" downpipe, instead of an intake which would benifit you in the mean time?

Do you have any facts to back up why you think your spoon 70mm throttle body is "the best throttle body out there"?

I would have to disagree, especially since there is no one part that is "the best" in every engine package.

First off when did i say that you have to install the parts you get 1 by 1?? As you can tell by this pic this how i went about things!!! so why would i suggest to install all the mods you collect??



You mentioned SUPERCHERGER for some stupid reason which is totally opposite of NA!! See with all motor you start with a motor already and its not a big deal to add some bolt on stuff as it would to add a downpipe without a blower!! Let me also explain something to you on how everybody modifies there exhaust!! do you think people dont buy cat-back systems because they do not have headers?? NO!! Either they buy the header or the exhaust and slowly work there way up very rarely do i see anybody in this forum buy the whole package @ once!! i know about 7-8 different members on this board who have cams and NO header but they are running cat-back exhausts and there gains are still pretty impressive there was no pwer loss!!

You also had questions about my good review about the SPOON TB why dont you do a search of the TYP R forum and then you maybe will understand where im coming from!!

For you, either stick with stock or go with 62mm ITR.

You are getting way off topic to try and strengthen your argument. If he doesn't know how the optimal TB diameter is effected by your intake manifold, do you REALLY think he knows enough to pick out a throttle body?

It was an example. Because a 4-1 kamikazee header would gut your powerband with out a supercharger, so why would it be the first mod you install?

Just like a large throttle body with out the engine package to properly match it, will gut your low and midrange.

I think you don't understand how a supercharger works. It replaces what would be the intake manifold. It does not run off exhaust gases like a turbo, which would require an turbo manifold. It is belt driven. Which is why you can use a kamikazee 4-1" header w/ 2.5" collector on an NA engine (which some people do, because they don't know about engine packages and how it effects the powerband)

Exhaust is completely different than altering the intake side of the engine. Stock, the exhaust system is very inadequate, where as the stock TB and IM are more than enough for bolt ons.

I want to know your reasons, because no TB is good for all aplications. Do you think the spoon TB is going to be the most effiecent for a 300whp NA engine and on a 150whp NA engine? If so you really need to learn more. Did you just buy it because the ITR guys said they liked it?

 

No more arguing with you!! obviously you have your own way of doing things maybe because you have a advantage finacially!! Just for everybody that is in 90% financial position with me slowly upgrading is just as good !!

I am thinking in the most financial manner. Why buy a part that is going to decrease performance now, when you can buy parts that will increase performance, and save the other part till when you need it?

The spoon throttle body is $522 from inline four

for that much money you could get
cam gears
v-afc
fpr
cams
highflow cat / testpipe

(depending on brand for some of those)

All of which would be benifical now, instead of reduce performance until you get around to doing modifications that will take advantage of the TB.

 

this is totally out of hand

even though one person thinks that a spoon (just a tapered itr t-body) is the bomb. does not make it the first mod everyone should do on their car.

do the standard intake, intake manifold, good header with 2.5" collector and free flowing exhaust. then get cams/cam gears + hondata. after you are done with that, get a throttle body.

if you are heart set on getting a throttle body, just send yours out to a machine shop or speed shop like king motorsports or ericks racinga and have it opened up to breath better.

stay on topic people

 

Obviously you guys do not read the CLASSIFIED section or check out PARTSTRADER.com SPOONTB sell for about $300 there!! Thats where i got mine!!

 

So it seems I should not worry about my Throttle Body for now and get some cams or something more useful.

I would like to keep my GS-R IM because I like the idea of the secondaries and how low end torque is imporved with it. I have had friends who have removed the secondaries and have hurt the low end. So if I keep the GS-R IM then my stock GS-R TB should be okay for anything right?

Would there be any advantage in getting a TB in the future even if I keep thr GS-R IM?

Thanks. Please don't flame each other.

If you care nothing of top end, and only mid-low, than you really didn't buy the right car.

Basicly the only ways to really increase low end is by increasing displacement or FI.
