hey guys im about to put on a gt40 intake on my car. the heads are stock, i wanted to know what size maf and tb should i get, that wouldnt hurt performance. i heard having a tb and maf too big, will hurt torque. will a 76mm maf and 65 mm tb help me, or can i get a 70mm tb without losing performance? any suggestions would help. i was think of gettin a 65mm tb, if i do do i need a bigger maf with stock heads?
thanks a lot for any suggestions or tips

What are your plans for the car? If you are going to do minor bolt ons you can stick with a 65mm but if you plan on swapping heads, etc. I would go with the 70mm

or the future i plan on swapping heads or atleast porting the stock heads...but thats not the first priority on my list. so for right now i just wanna get the gt40 intake on and get a big enough maf and tb to gain more power and not hurt power? any suggestions on sizes

Some people say that it will hurt your low end but I never felt a difference when I ran a 70mm on my 88 GT.
