i would buy once and just get the 70mm it wont hurt nothing. it wont hurt tq and you will make more power

 

so runnin a 70 wont hurt me with a stock intake

 

Unless you're running a serious setup 70mm will be plenty. If you're doing a head/cam swap in the near future you might as well buy the 70mm now, if your stock intake opening isn't 70mm it may hurt you a lil but who cares.

 

not to jack the thread, but does anyone happen to know the size of the opening of a Tubular GT40 intake manifold?

 

if it's the same as the Cobras then I believe it's 70mm.

 

so would a 75mm MAF, 70MM TB be a good set up on a GT40 tubular? or is the 75 MAF a waste?

 

thats perfect

 

You have the right idea. MAF should always be bigger than the TB. Perfect.

 

I'd just run the stock MAF until you do a head/cam swap and get it tuned.


Edit: didn't see you had a 100 shot, I'm not good with nitrous.
