As the title suggests, I am wanting to know about these mustang 75-80mm throttle bodies that i have heard some people are running. What I want to know is

Where to get one from?

What are they off?

What modifications do i need to make to the hardware? (i.e. inlet manifold and water lines)

What computer/ecu upgrades are needed?

And how do they compare to EZboy's throttle bodies?

I have searched but have only come up with people saying that they have them and other people asking question about them with no responses.

The Ego has one. Its an 80mm throttle body. I believe the 75mm also fit onto the cars. i asked him about this last month and he doesnt remeber what model they come of. but you can pick them up quite cheap as i hunted into this, and i will be going forward with it in the future. Exboy TB is just high flowed, this throttle body is bigger, allows more air in, thus more response, and probably a bit more power down low.

Waste of time on a stock or near-stock motor, the 65mm factory unit flows just fine, and probably is fine for a fair whack above factory output.

yeah thats pretty much what i said that i found in the first post, also wanted to know how they compare against EZboy's not how they are made, thats all written in the thread on them but thanx anyway.

Nah mate, larger TB can only give the illusion of more power down low, as you are effectively getting a larger throttle opening for the same pedal travel.

It doesn't actually give more power (well it can at the top-end IF the previous TB was a restriction).

65mm will flow fine up to 300kw atw, Sr20's are 65mm and arent needed to be changed until you are pushing serious power, as for coolant lines i daresay you would just block them with water caps or a new pipe and just double it back off the core. No idea how you would fit it to a stock manifold, but being that your looking at EZboys unit if you supply him the TB he will make the inlet to fit that TB, with the bolt holes etc. Also no clue how would you go with the Cruise (if you have it) and the ISC and TPS adaptation. PM Ego about it, or Jasonsvrx i think he has one as well.

i would've PM'd him about it but i thought of making a thread so others could get any info required to do the same if they were looking at doing this in the future.

as for the TPS i can only assume that you would have to use an aftermarket ecu or piggyback to tune to the mustang one, i wouldn't think that the magna one would be used hence the reason i asked. I also have cruise but not really fussed on it so if it gets lost no big deal for me.

forgive my ignorance but what is ISC??

Forced induction can't be compared to NA cars when deciding on peak flow through the throttle body.

Yes and no, i was talking about restriction overall, being that there is only a couple of guys on here that have upgraded TB's they didnt have any before and after dyno runs, or bench flow numbers, also they were done with a lot of other mods at the same time so definitive results are not there. But that being said prove me wrong, you have me interested now on whether its a decent upgrade in terms of power curves and peak power.

regardless of end figure cars fitted with a "flowed" throttle body definitly are more responsive and give the illusion of more power.. and really do u want to do a mod that looks good on paper or feels good when ur driving??

anyways back on topic..

I know ego has the tang's TB and has no cruise... and it doesn't look like much modification was required to fit it..

therfore benny boy why don't u make one which can incorporate the cruise :D and bolt on directly...

Then all it is then is the almighty Butt Dyno, nothing proves a mod like numbers on paper! but yeah as i said before PM ego to post on here or post up what he says in the PM.

no quarter mile times prove mods u can't compare dyno figures..... this has been covered numerous times...

But even then they cant always be accurate, Temp, Humidity, Track temp, The driver, The car, Fuel, Tyre Pressure. All variables when the 1/4 Mile, given the dyno has about that many variables as well, at least back to back's give a resonable indication on what the car is making. That and you have the graph to physically show you how much Nm torque or Hp its making across the Rev range.

That's right guys, everything that doesn't dramatically alter the car's combustion dynamics is almost guaranteed to be subjective depending on every variable you can throw at it :D Yayyy~

Upgraded throttle body would be a waste of time unless you've done some serious breathing mods, larger valves and lift, larger plenum chamber too etc etc... I don't even agree with flowing a TB really, the gain involved wouldn't be great at all.

Yep that is correct, as for EZboy's TB's they dont give any extra power, all they do is remove the lip thats inside the bore and gives the pedal a lot more response ie only a 1/8 depression instead of 1/4. Ezboy will be able to explain it better, but they give better pedal response not power.

Yeah, it would improve flow rate (hence the name I suppose) and driveability and so on... Ezyboy does know what he's doing though :cool:

so does anyone have any answers to the original questions asked??

your going to have to ask The Ego for them i think

Im maybe a bit slow..:) I didnt get any PMs but just found this thread..:)

I have a 80mm Mustang TB.. I dont have any cruise and it has a XF Idle Motor and a XB 5L Trottle Position Sensor.. I dont know what the differance was in power as i fitted on on the NA rebuild with a million other mods..:)


Ask away with the questions..:)

all thw question i asked arfe on the first page but i think that half of them can't be answered due to you having it installed with a bounch of other mods.

I didn't send you a PM cause i thought it was justy be pointless. If you could answer any of the Q's from page 1 it woulld be greatful.

Where to get one from? Dont Know

What are they off? Dont Know

What modifications do i need to inlet manifold? Cut & Weld Plate For New TB

What computer/ecu upgrades are needed? Depends on other mods. Id Say Piggy Back as a Minimum

And how do they compare to EZboy's throttle bodies? Dont Know


Hope that helps

not much really:rant:

ego was never known for knowing much :P
