If I put a 65mm Throttle body on my car will I need to upgrade the MAF? I don't think I need to, but I wanted to make sure. Also I know throttle body spacers are worth buying but what if I can make one? I mean does it help at all? if It does I can make one for free....

[whitemustang02]

I’m assuming u r na so u shouldn’t need a new maf also is ur upper intake ported to mach the new tb because if it isn’t u should do that next and a tb spacer is like adding .5 hp to the crank so I wouldn’t really bother trying to make one

[scxc15]

Yea i'm n/a. Its not ported yet. I cant decide whether to port it myslef or just order one but I'm getting a BBK 65mm tb for only $100. They are usually like $240

[El_Cangri]

Get it ported by a pro or buy one already ported. Since they know what they are doing they would sqeeze every possible horse out of it

[whitemustang02]

if u r gona get it ported for the th have the hole uper and lower done all at once otherwis u wount see that big of an improvement

[El_Cangri]

yup.. a t.b isnt worth it unless u port the upper and lower intake if you dont do it there will be no increase in h.p

[scxc15]

My dad knows how to port them so no big deal. I'm going ahead and getting the tb since its such a good deal tho.

[scxc15]

How big is the stock throttle body?

[scxc15]

Also the only time you need to upgrade you fuel system is when you either s/c, t/c, or put a storker kit on your engine. Is that right?

[El_Cangri]

the stock t.b its 60mm i think

and you need to upgrade the fuel system if you exceed the 250-320 horses cuz that's where the pump cant send enough fuel I may be incorrect tho

[whitemustang02]

The stock tb is about 62mm when I measured mine I got something like 62.23mm
And as for the full system if u go FI u will need to up grade it. if u have a lot of work done to the engine on a na car u may want to upgrade it depending on what all is done and u may need to up grade it if u have an large nitrous system.
The reason u would need to upgrade the full system is because the current one isn’t supplying enough fuel and so ur car is running lean

[whitemustang02]

It may be around 250 or at least that is were I would start to get a little wiry

[El_Cangri]

k yeah i put 250-320 cuz i wasn't sure thanks for the info

and like he said dont upgrade fuel system unless you really need to and have a high fuel demand that cant b supplied

[Onemanzu]

you will know when you need to upgrade the fuel system... your car will start to cut out and the power will cut down a lot... if you just post the TB you will see a tuny bit of gain but it doesn't hurt to do the hole thing just make sure its not on the car when you do this...

[Avaric3]

if you want, i can sell you ported and polished upper and lower intake and ported heads so you can take advantage of the extra airflow. links in my sig

not a chance
more like 56mm
my 65mm throttle body will EAT my stock throttle body

lol and your wrong on the gas lol
more lean?! so 93 octance has more volume? lol
87 octance burns FASTER then 93 octane
you need it to have a SLOWER burning fuel lol omg

that you are WRONG about your octance information that you passed out
i usually dont look at these threads with this title but good thing i did
also the stock throttel body IS NOT 62mm

[whitemustang02]

i dont understand what u r trying to say
if im wrong im wrong i will exepth athat with out a question but i would just like to know why so i can learn from my mistake

Yeah and a TB isn't a great mod either unless its all you have left to mod!
