Mag Intake on an ATX

Just before I buy all the parts I want to double check that I will be able to basically just bolt up the mag intake on an ATX (and do the wiring yes) without getting a new TB or anything like that.

I can see why not. I would try to get a magnum head while your at it to and that should give you a nice little gain in power. Hint hint atx->mtx swap.

Haha never to fear, later in the year im actually going to do the swap, just gotta save two paychecks for the tranny and all the other stuff
what tranny would you reccomend the 3.55 or 3.94? :O

get the 3.94 transaxle. I still get 31.5 MPG with mine @ 3,500 rpm in 5th (about 75mph).
the magnum intake manifold bolts right up to any sohc head. you will need a replacment bellows tube because the intake to the intake (

) is at a different angle then non-mag mani's

How do you manage to get 31mpg? I drive like 80% highway with the cruise set at 75 and i can only manage 28mpg or so...guess your just lucky as hell!
As for which tranny, 3.94 FTW!

well, stock i got 28 mpg... mods increased it to 31.5 highway and 25 city.
intake got +1 mpg, cam got +1 mpg, LTH got +1.5 mpg. i was very surprised to see this happen
right after the cam install i got like 10 mpg

but after the computer "learned" the new flow it adjusted and went back up.

For the bellows tube, can I just get some piping and do it myself, or do I absolutely have to purchase the stock mag bellows tube?

the bellows tube is different. you could bend your own, buy one, or try and bend/manipulate a non mag bellows tube to fit.

highway ive pulled 36mpg with 3 people in the car, but i also have alot of 'breathing' mods and 15" wheels (stock snowflakes were used, not my track 15's

)
if you can, locate a PT tranny... it has the 3.94 with the .72 5th gear (the rt/acr tranny has .82 5th).... the .72 allows the car to still have great torque throughout gears 1-4 but 5th gear has the theoretical gearing of the 3.55 with .82 5th so you still get good highway mileage

if think that if i whent about 55 (2,500rpm) i could pull some good mpg numbers

My car averages 33.3- MPG, I have 15" K1s, iceman, stock magnum exhaust and intake manifold, and an UDP. And of course, a 5spd. My best mileage was about 42mpg, Which I am not sure how I got, other than buring Nevada gas.

Wait... wha? What kind of cam? I've always wanted to just throw the Magnum cam in mine to see what it would do, but I didn't know the consequences.

)

. I do enjoy the better mpg when im not hard on the throttle tho.
