Hey guys,

I've done a lot of research on this site about throttle body's, but I still have a few questions remaining. It seems that the most common aftermarket TB sizes are the 65mm and 70mm. Right now, I have a BBK CAI with plans to get an upper and lower intake in the future. I also have full exhaust - headers to the tailpipes. Which size would you guys recommend? Also, is there a particular vendor you would suggest? I've seen all kinds of sites online advertising TBs such as Accufab, BBK, Edlebrock, etc.

Thanks in advance for the help.

Anyone?

for a mostly stock car you want a 65mm

My current mods are:

BBK CAI
Centerforce DF clutch
Pro 5.0 shifter
BBK equal shorty headers
O/R Prochamber
Magnaflows
Aluminum driveshaft
3.73s
Moser 31-spline axles
Auburn 31-spline posi

Is 65mm still the way to go?

primetime5.0

yeah even with heads and a cam 65mm will still work well

Hmm... gotcha.

Anyone else? What brand should I go with... or are they all pretty much the same?

primetime5.0

there all pretty much the same, but I have heard worse things about professional products TB's as opposed to others

I figured as much. Would I run into a problem if I bought a 70mm? I do plan to keep upgrading the intake and engine in the future... so would it be worth it to go ahead and buy the bigger one up front?

primetime5.0

nope I run a 70mm on a bolt on car and it runs good

Thanks for the quick responses & information, primetime

Anything else I should know before purchasing a TB? Any additional parts or upgrades necessary?
