Will a manifold that is made for a rb26 w/o itb's bolt up to a 25. The reason I'm asking is cause im bout to upgrade from the stocker and I've narrowed it down to two choices r.i.p.s or hypertune but they don't have a hypertune listed for a 25 So I was wondering if it would bolt up

we make an adaptor that will allow you to bolt up the rb26 itb's and manifold to the RB25. Without it, it will not bolt up (with or with out ITB's).

If you are uninterested in the ITB's than you can always run spacers that ultimately replace the ITB portion of the intake system.

Hit me up.

$1400?

and this is better than a real greddy manifold how?

ITB's on a turbo car arent nearly as effective as on a NA engine.

i am not worried about it being better just different. they are only a hand full of people stateside that have one everyone has a greddy. there really is not alot of difference in the price you pay 935 for a greddy plus s/h then you still have to buy the tb or the adapter plate for the stock tb for 160 so your almost looking at $1150 whats an extra $250

And I have 26 ITB's on a 25.

why would you put a non itb 26 manifold on a 25 when u can buy a 25 manifold w a large single tb? that sounds like a question a guy would ask that states a 14.7 is the perfect afr for a boosted car

ill simplify the question for those who dont understand it. but coolwhip already answered so i know, does a intake manifold that is made for a rb26 with a large single tb instead of itb's have the same bolt pattern as a rb25 intake. the reason i was asking is because i dont want a greddy and i wanted to see what other options i had
