HO upper intake and throttle body

[89GrandMarquis]

Will it make a noticeable difference if I just put the upper intake, throttle body, and egr?

Yes. The change was quite noticeable. You'll like it.

Ah, it will be fine, you'll need to get your stock EGR spacer bored out to 60mm. It will help out even a stock lopo motor, and should run without any issues. I ran the HO upper and TB on mine...

My mistake, its a standard HO intake from a 90 Mustang GT with the stock 60mm throttle body/egr. I was looking up something about the cobras using a 65mm throttle body at the same time.

Really? They never made a cobra in 90. 93 was the first year for the return of the cobra....they had stopped in the early 80's.

If it's a Motorsport Cobra intake, it will require some mods...

I have both an upper and lower intake from a 90 Cobra including the throttle body, egr, etc. Will it make a noticeable difference if I just put the upper intake, throttle body, and egr? I'm not going to upgrade the cam or the heads since this car runs too well, so I don't know if it will run poorly if I don't do a complete HO conversion.
