Will this fit on a 90 gt 5.0? And would i need any additional parts to make it fit?

What size is the throttle body hole (70mm) (75mm)? Because I’m running the stock intake on my 1990 LX and it’s only (65mm) and my (70mm) throttle body and spacer are creating some back pressure.

The Edelbrock Performer EFI Intake Manifold utilizes a 70mm Throttle body opening.

The Edelbrock Performer EFI Intake Manifold will clear the stock hood on 86-95 Mustangs as long as an additional intake spacer is not used.

This could be a handle full of issues that could be causing this. We would highly recommend taking your vehicle back to the installer as it was not smoking prior its installation.

what would be a good Throttle Body for Edelbrock Performer EFI Intake Manifold for a 89 3 answers

It depends on the other mods you have done to your car. If you have just basic bolt-ons (exhaust, CAI, etc.) a 65 MM would be fine. If you have heads and cams I would go with a 70 MM and if you have a blower I would go with a 75 MM.
i had this intake a while back on my 93, and I ran it with a BBK 70mm throttle body. a 75mm will be too big for the intake port of the intake manifold itself and a 65mm will be too restrictive.
65 mm tb if use is for street, maybe a bit more responsive. But can't go wrong with either a 65mm or 70mm. 75 if u go to the track

Great intake

This is a great intake. It's nice that you can remove the back to port it.

Worth The Time and Money

I've had this manifold for a few months now on my 95 GT. I could definitely notice a power gain when installed with the SR Performance CAI. It took some time to get everything in place working by myself, but it fit perfectly. Just remember not to over tighten the studs and bolts because it's very easy to strip the threads in the aluminum. It makes a nice addition under the hood. Definitely recommend this to anyone looking for style and performance under the hood.
