Port and Polished Throttle Body

iSlacker816 · Sep 12, 2011

I have 2 choices for my truck a 50 mm and 52 mm, now being a 2 mm difference will the 2 give it a little extra umph? 50 dollar difference is the only reason I'm asking, but for 50 bucks I might as well go big. Just curious if it'll be that big of a difference?!?!?!

i agree for $50 you might as well go big, but somebody will chime in soon who knows for sure.

go big or go home rite lol hell for an extra 50 bucks why not

iSlacker816 · Sep 12, 2011

Yea I think I'm goin with the 52mm

Going that big I would also modify the stock kegger, or get a M1 intake also a SCT tuned by Hemifever.

Whats the port size on the actual intake

wermbang · Sep 13, 2011

Stock throttle bodies I believe are 48mm

KGBIGCOUNTRY · Sep 13, 2011

Ment where the TB mounts to the actual intake?

I'm pretty sure they're matched to the tb at 48mm

I was always kinda curious about that too. If it really made a difference to go to a bigger one.

50mm if you tow things. 52mm if you just want to go fast. 52mm will move the power range up the rpms a little. dont expect to feel a whole lot of a change with either one. tb's go along with other mods.

i would save the money and get a tuner.

Now I was looking at intake manifolds such as the M1 but they say theyre for carburetors, will it accept a throttle body?

talon6 · Sep 14, 2011

here's the intake i have. and a little m1 info too.

Hughes Engines

iSlacker816 · Sep 14, 2011

hell I'd love to have a F1 but I'm not ready to dish out 600 bucks for an intake, Id really like to get theyre top end kit with intake and everything!

talon6 · Sep 15, 2011

i hear ya. 600$ is a little steep.

iSlacker816 · Sep 15, 2011

Would I need to get an new intake if I get a 52mm throttle body? Since all I have is an intake and exhaust, should I just got 50mm?

wermbang · Sep 15, 2011

I would say with out getting into the internals of the engine or changing the intake I would get the 50mm, but others I sure will have their opinion too.

talon6 · Sep 17, 2011

you wont "need" a new intake. i ran my 52mm for awhile with my stock kegger. your stock one will work. and i would also suggest the 50mm tb.
