what do i need to upgrade a throttle body from a stock to a aftermarket? also what parts might i need to complete this task?

 

You gotta give a litte bit more info if you want you more responses...

Car/year/engine/what type of aftermarket throttle body are you looking to get?

Have you considered using a bigger OEM throttle body...if you do some searches you'll see alot of other Honda TB's will fit on most Honda engines and dramatically inscrease the inner diameter without having to do anything crazy at all, and alot of them can be found on craigslist/local junkyard*sometimes*

 

i have a honda civic 93 dx sedan. Stock motor. d7 motor or something. what bigger OEM honda throttle body would fit?

 

any other mods on this engine?

 

a bigger tb is not gonna do anything to that motor for power, you have to upgrade the inlet mani and the tb to make any kinda power

 

you have to port match the intake manifold if u want to see any gains.

 

considering what i just said, i alright knew that

 

the quote wasnt to offend, he was elaborating on what you just said

 

sorry didn't sleep good and i was a little cranky

 

i have a d16Z6 motor now a D15B7, and its a stock tb and i want to put an 80mm on there.

 

i meant had a D16Z6

 

80 mm?! On a D?

 

Hell yeah!! Go big or go home!!!! hahahaha

 

On a D though? lol Even with tuning is there any advantage for anything over like 72? Can any of the D intake manis match up to that?

 

it will still work fine, besides a difference of 8mm is hardly anything
performance on the other hand won't make much difference except perhaps the highest rpms, which you probably don't drive at all the time, and only at WOT of course.
its your money, but in my opinion not worth it. if you really are set on a larger TB just get one off an integra or something.

 

A larger throttle body will hurt more than it will help in your case.

You might gain a minuscule amount of top-end power, but you'll probably lose low-end power. You'll also lose a ton of throttle modulation. You'll also lose money.

 

dude 80mm is huge I have d16y8 with a 56mm TB like everyone says theres no point if ur IM is 56mm and u want a 80mm

(i think urs is the same size btw)
Im upgrading to a 60mm below are acouple engines with the 60mm Is not that big but u can get a used one for around 20bucks as opposed to a aftermarket one for 300
b18c1 - 60
b18b - 60
b16a Sir2 - 60
b16a2 - 60
b16a3 - 60
b20b - 60
b20z - 60

 

ok thanks for all the positive input guys then ill stick with a 72 to then, cause i pretty sure that its not very big.

 

hahahahahahahahahahHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA HA!


a stock b series TB will be more than enough since they are all 60mm or bigger. then once/if you upgrade your IM you will be set. 72mm is ridiculous, unless your d15 has a custom made IM and is twin charged with nawzzz

 

72mm is enormous. You have a stock d16z6, so use a stock d16z6 throttle body. A 72mm throttle body is 65% larger, and you'll kill modulation.

 

This thread is messed up! There is not a lot to be gained by a throttle body upgrade, usually 3-4hp at best, and that's with the right size for you engine. Your single D doesn't flow that much air, i can't see going any larger that 60mm as an upgrade for that application. If you go too big, you will have major idle issues.

Even on a high flow engine like a B18C-R i am building, i went oversize, and stayed with a 65mm to keep good street ability.

 

you can gain hp but loose TQ at the same time so to each thier own.

 

ok cool

 

does anyone know if the lug nuts matter cause i just bought some sparco rims for my car and the lugs are different then the old ones and so i am trying to buy new ones. the ones i am looking at are blue and 12x1.5. ohh and the rim size is 14"

 

Make a new thread for completely different questions like this.
