One of these days, youre going to have to post some research notes. Cough up the knowledge!1993 Ranger: The restriction is the head, lower and upper intakes in that order.
Factory TB is fine for 200+ HP.
On my turbo engine I ported the head, mild gasket match and a MINOR engine rebuild at one point and LOST 2psi of boost, including the fact that the intake gasket was SHOT and missing some large sections at the head. So the head is the major restriction at least in the D port era like my '90 is running.One of these days, youre going to have to post some research notes. Cough up the knowledge!
LOL, not until I finish the bottom end and dyno it...One of these days, youre going to have to post some research notes. Cough up the knowledge!
All fuel injected Rangers came with Cold Air Intakes(CAI) from the factory, if this has been changed then you may have found your problemThe issue I am having is that half throttle it bucks full throttle it pulls thinking it needs more air has cold air intake on it already didn't help none

Tell tale............if you can HEAR the AIR FLOW going into the engine then its RESTRICTED
Many like that noise, that's fine, just know it means air is turbulent(the noise) so restricted
