tb question ??

[red93camaro]

ok i was lookin at a new tb for my car cuz my friend said it would help out alot and i seen on ftpp.net this NOTE: These Throttle Bodies will only fit 3.4L V6 with modified upper intake manifold........so wtf does that mean i gotta bore out my mainfold to get one ????? help

[viper98885]

Some people have had their upper intakes modified (as in custom sheet metal modifications) in order to fit the LT1 throttle bodies. This is the only way that they will fit.

ive also seen the Tiago custom modification
cut off the intake manifold plenum of the 3.4 and add the lt1 intake manifold entry point....i believe he used to seel those intake manifolds too if im not mistaken.
Check his website for more info

RSM Racing 62 mm throttle body:

That RSM is a stock replacement? I am doing the LT1 pretty soon myself. i am just going to take it to a welder, mechanic person. My car cant breathe at all with a 50mm throttle body. It will do better with 48x2 though. [img]smile.gif[/img] Then I am dynoing, and going to the track. ;)

please do get dyno numbers before and after the install of the new TB

yes the RSM is a stock replacement, however the inlet of the plenum isnt 62mm so you would need to have it bored out to match the TB

note: no one used steel on their little box to mount the TB to the plenum... you cant weld steel to alumnium (the manifold is alumnium, you have to use alumnium sheet metal)

i never thought a lager TB would make that much a of difference unless you have some major work done

Flamespike is thinking right. you will need a lot more then just a bigger Tb to make more power.
The inlet is about the same size as the Tb.
You need some custom metal work to get a bigger TB on there and make use of it.
The 75mm TB is all most ready to weld so it will be done soon.

Holy crap, thats awesome man, ever think about doing that to the 3.4 intakes??
by far one of the most awesomest <please excuse the gay language> thing ive seen in a long time

[oil pan 4]

I had not thought about doing it to a 3.4 intake, but I think it could be done.
