Just by looking at the 2, how can you tell them apart? also what does the big 16g flow compared to the 18g? THANKS!
 
Go with the Big 16G it will get you into the 12's with all the supporting mods and good tuning. Dont know a whole lot about the 18G but I think that a ported big 16G is about the same internaly. The good thing is my big 16G mounted right up with no mods so thats got to save some money over tha 18G..
 
i have heard bad things about the 18g. Go 16g or 20g. And if u want a car that runs mid to lows 12's with FWD you may wanna go 20g. I'm planning on just touching 12's with a Big 16g on FWD.
 
I havent heard anything bad about the 18g. Its just alot more rare to find then a 16g or a 20g. I have seen ppl running 12.0 's on the 18 g. So it has some potential
 
Well here's the thing. Someone practically gave me the 18g, so I'm just going to have to deal with that for now. Anyone know how to tell the difference between the 2 just by looking? and how much they they flow?
 
some 18g's come with a tdo6H and some come with a tdo5H. which one do you have?
 
i recently also got a great deal on an 18g and havent put it compeltely on, i still have to put the oil return line on but it wasnt that hard to put on, and i beleive it is a 50cmf difference from the big16g. but i have heard some crazy top-end power from the 18g, takes a bit more time than a big16g to spool up but its does have power and potential.
