Throttle body plenum upgrade
So I already have my nitrous kit next is throttle body and plenum. I have a freeflowing exhaust and I have been looking at air now. I saw the bbk plenum throttle body 78 mm andthe accufab 75 throttle body. Both are the combos.anyway I was wondering if they are too big for my motor and will they bog me out. The bbk combo is 200 less than the accufab and was leaning towards it but I still have stock internals... I am on a pretty tight budget so I don't wanna go to big. This motor will stay Na .... Thanks for your input

If you want results,the accufab combo is the one.The 75mm throttle body might be a little over kill to what you need,the 70 would be perfect.
The whole idea to an aftermarket plenum is due to it's design of raised roof,and shortened hosuing length.
What i did myself before going to the Bullitt intake was match ported my upper plenum,changed the radius a bit at the floor so it gave a more smooth flow into the lower intake,and added a spacer to raise it for added plenum volume.I did notice a crisper throttle responce,and seemed to run free'r at higher rpm's at wot.
But i did not up grade the throttle body,i kept the stocker,and ported/smoothened it out.

Nice.... Ok so I am pretty mechanically inclined and am taking pride in that I am gonna do all the work on this car myself and you seem to know what your talking about so if it isn't too much trouble can you email me step by step instructions on how to do this and what tools I will need for the upgrade. I value your experience and would like to take advantage of your experience.... everettmorash@yahoo.ca.... I know I am asking for alot but pics would be a big help too.... Thank you
It was easy to do.As long as you got a die grinder,nd use common sence,your good.
