Hello, I've been thinking of replacing the throttle body on my '89. When I go on sites to purchase a new one I see there are two available. A 52mm and a 58mm.
My '89 being a base coupe I'm sure has a 52mm from factory.
I'd like to upgrade to a 58mm throttle body. However there is always a side note listed by seller which reads:
"58mm Throttle Bodies require port matching of plenum to allow maximum flow."
Can someone please tell me what this means and also is the 58mm to much for my car to handle?
Obviously I'm less than novice when it comes to working on the engine.
Expecting quite a bit of poking fun and side wit agitation..... cool... I can handle it ..... as long as answers to problem are thrown into the mix.....
