Ok, so Cory from MP is building another 2.4 normally aspirated motor to swap into a first gen.
We are building new 2.4 10.5:1 compression pistons in a asymetrical design that will have minimal piston skirts to reduce drag and weight.
Also for fun, we plan on testing out different intake and exhaust manifolds. One of the manifolds we are going to test out, is the GEMA (Global engine manufacturing alliance between Chrysler, Mitsubishi, and Hyundai) intake manifold from a 2.4 from 2007-2013. This intake manifold is found on Patriots, Compasses, Avengers, Calibers and other Chryslers 2.0/2.4’s.
This intake manifold has plastic construction, nice smooth runners, large tb bore, and active intake manifold shutters to improve lower end power.
This manifold is HUGE, and it will be a challenge to make it fit in the first gen engine bay and clear the starter and fans.
But, it will be an interesting experiment. The first thing we’ll need to do, is make an adapter plate that bolts to the 2.4 NA 1995-2001 cylinder head. We’ll do this by taking an older intake manifold, chopping it off at the runners, and then custom cnc machining a plate to weld onto the oem intake manifold. Then the GEMA manifold will bolt to that.
Then, after that, the challenge will be to make the active shutters work, and test different rpm ranges to see when its best to have them open and closed. We imagine its best for closed shutters on lower end, and open at mid and top end.
Anyways, onto pictures.
This shows the backside and the shutters blocking the passage for lower end.
Here is a 95-01 NA 2.0/2.4 intake manifold Hondata heatshield gasket showing the similarity of the ports.
Nice smooth runners, tb opening on driver side, and large tb opening. Great for NA use!
More details to come!
