I've done Big Bore TB Mod on some 4 Bangers. Great Throttle response, not much help on 1/4 mile times And this was tested against prior consistant runs...

It was a Larger Throttle Body, with Larger Plate, nothing stock on the set. like I said, great response, but trap times were improved a tenth of a sec if any...

I've already inspected our TB, and cant seem to find any room for increase in size. Most TB's on other vehicles are in some way hour glass shaped boring them out increases volume of air flowing through, there for increasing initial throttle reaction. Not sure if our Taco's will feel this benefit??? Like I said the TB looks straight.

IMO TB upgrade is a wasted attempt for HP. Save that money and put it torward a mod that will work, ie... MAF Cali. Even a stock motor will benefit. Our trucks run Rich as hell out the factory. And Aftermarket products tend to cause the ECU to pump more fuel due to the mods...

This TB plus an MAF, then a P&P Harness, plus tuning products like an LM-2 will cost you in avg: $1100

Thats not including the Aftermarket Intake or plain ol drop in filter...

If you are gunna go that route, why not cut the hypothetical mod out and go with a currently proven product like APR X-1

After market T.B's vs. a bored out T.B's is apples and oranges. I see no point in say boring out the stock opening to 72mm and leaving the butterfly 70mm. The 70mm will be the bottle neck. An aftermarket 72 mm T.B. will be 72 mm at the butterfly aswell as the opening.
Just saying.

I also agree in that a T.B. is not the best bang for your buck. Not in a NA Tacoma atleast.

That sure was fun when XrunnIT showed up.

It is a rebuild stock TB will be over bored 2mm and will have the butterfly replaced. They are in the proccess of making one. www.proflowdesign.com

If thats the case what is the price for the core charge?

ie... Pay 250, recieve product, send in stock unit, and reimbursed say 100-125...

If that would be the case, then it would be more doable. But 250 for a 2mm bore is a little out there especially without any R&D. And just because it gained performance on other vehicles is not prrof enough to say it will produce any gains for the 1GR...

The do know that the 1GR throttle is a drive by wire right?

Do they know that the 2UZ-FE TB could be used with the stock air surge tank (with some slight modding)?

i can't seem to get my head around this one. i understand big bore throttle bodies and airflow, where i'm confused is at the throttle body itself. it does not have a direct connection to the accelerator pedal, it's controlled by the ecm(engine control module). your foot is just an input(or request for more air) it's the ecm that makes the determination of how much air, of course basing off of others factor, i.e. intake air temp, air flow, load. these just aren't the same as far as your old mustang goes. that's why urd maf calibator works so damn well.

i think its the fact that if u go WOT, you're pulling in a little bit more are than the stock TB. that is also dependent upon the intake as well i would think

if you look at the throttle body on your truck, you will notice the black plastic housing attached to the side of the TB (throttle body). That is a motor that controls the throttle based on the TPS (throttle position sensor), and some other sensors. All monitored by the ECU.

The URD Maf cal doesn't have anything to do with the DbW (drive by wire). It alters the Air/Fuel map for the ECU.

AAHHH Too many acronyms for me to follow

exactly what i thought. the problem i have is that throttle won't go WOT unless the ecm requests it, not the driver. you would have to change the map for the throttle in the ecm.

Hmm, Dosen't the APR X-1 have some sort of effect on the TPS

Believe it's called Pedal vs TPS Monitor
