My set-up currently is

jdm b18c
CTR intake cam
BLox intake manifold
Ebay cold air intake
Ebay special header
Full 2.5inch. cat-back exhaust

It's a pretty simple set-up and i'm looking to make 170-180whp, but since i'm planning on going for a full dyno tune I wanted to know if having my stock throttle body bored out to 64mm by maxbore.com for a $100 would benefit my set-up in anyway. This is my daily driver and weekend autocross warrior.

So my question is would it be worth my money for my set-up to get it bored out to 64mm ?

 

A better header would probably be more worth it.

Definately, but unfortunately I have a DA and because of the Gigantic crossmember I can not fit any nice kind of 4-1 header or anything.

 

why not get a 4-2-1 then?<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by redDAinteg &raquo;</TD></TR><TR><TD CLASS="quote">

i do have a 4-2-1 megan racing header.

 

that header sucks, but i don't think you have much of a choice with the da.

A 2.25" exhaust would benefit you more for the money than your 2.5"

So long as your intake mani has the 64mm bore it should help to do the tb.
