Attention Auto Geniuses, Nairb Is About To Lose It!!! Help!!!

Guys,

I replaced the engine on a 1995 Mazda Melinia S. The engine is a 2.3 Millercycle with a lysholm screw type supercharger.

The engine will run and idle fine, but will not rev above 1500 RPM even if you hold it wide open.

This particular engine has a dual intake manifold system similar to a Ford 3.8/4.2, in that it switches a valve when you gun it to allow the supercharger to do it's thing.

I have checked exhaust backpressure, and fuel pressure. All within specs. The engine runs just the same with the exhaust removed so no plugged exhaust.

I need information if anyone knows where to get it. Desperate for help!

did you check to see if the TPS was out of adjustment? im pretty sure those cars have one, and if its off then it'll throw the whole computer off. also, check to see if the MAP sensor is bad (also, if it has one). i dont know very much about Mazdas.... just throwing out ideas...

I would think that you might have a restriction of some kind. I have seen exhaust pipes that are 2 layer and the inner layer can collapse and the outside look ok. I know on my chevele if I have the choke on about half way and try to pull away the engine wont go over about 3000 rpm. If I open the choke it will rev right up. If the engine wont flow enough air it wont rev up.
