which size should i use on my t3/t04 turbo setup with b18b. 3AN or 4AN. someone told me 4AN is too big? someone else told me 3AN is too small? what size are most people using? thanks in advance

 

Either should work fine. I'm personally using 4an without any trouble, but I know lots of people running both perfectly fine. I got mine here, good prices http://www.secureperformanceorder.co...6&CategoryID=3

 

Most tell you to go with 3AN because 4AN may allow to much oil, and can ruin your oil seals. 3AN will provide enough oil. There is a mixture of both 3AN and 4AN on this board. i personal use 3AN.

 

either will be ok...4AN will flow alot more...its all about personal preference though

i have a 3AN...

 

thanks that helps alot

 

i got 4an .

 

I use 3AN on my race car, but the import thing is to make sure your return line is large and not kinked in anyway, try to have a smooth return line, as straight down as possible so that the oil won't back up. number one coz of smokin and hurting turbo bearing

 

i also have a 3AN, cause that's the size rev-hard kits come with. i've seen no problems with it, but when u look at the hole, its real small. next set-up i will be upgrading to a 4AN.
