The Draw-thru setup (9/13/04) Here we have finally successfully turbocharged an AMC six cylinder using the "draw-thru" method. What you see to the left is everything it takes to make the turbo work. Notice the overhead exhaust. With some pretty exotic fabrications, we were able to make an adapter plate to hang the turbocharger right off of the exhaust manifold. However, in doing so the turbo must be mounted backwards in order to give clearance to the steering column. Thus, you must come up with some really wacky way to get the exhaust moving in the right direction. Besides all that mumbo-jumbo it looks really cool going over the valve cover. |
| To provide ample fuel/air mixture at boost, and Holley 500 2 barrel was used. The stock fuel pump works fine with this setup. To regulate boost, we installed an IMPCO TC2 Turbocharger Boost Control Regulator with an 8 pound spring. After we got a boost gauge hooked up, we found that the regulator did a very poor job of regulating, as the manifold pressure would sometimes reach pressure as high as 15psi(g). There's not much we could do about that except pay attention while you drive it. I need a different rear end. There is way too much motor there for one tire and it gets cooked. And no, it could not possibly be the way I drive. | |
The Blow-thru setup (9/28/04) Right now the car is being driven with all the stock stuff. Yeah I'm ashamed to say this but I'm running around town with a little ol' one barrel on that dude. I drive my '76 Kawasaki every chance I get, but as my only mode of transportation for this winter I needed the Gremlin to be very reliable... even if it means I have to go slower than the speed limit on the highway. |

We experimented with this idea early on in development of our turbo kit. As you can see in the picture to the right, we made a carb hat capable of pressurization. In this scenario, the turbo would still be mounted onto the exhaust manifold. Now here is our really cool idea: we are going build a 258 with a 4.0l head with oversized intake/exhaust valves and use the 4.0l manifolds with the 258 block and crank. We will put a larger lift cam in there to utilize the greater head flow. This will allow us to put more air through the motor, in turn allowing more boost. Also for this mod, we hope to be able to bring the turbocharger to the opposite side of the engine it is on now by plumbing the exhaust underneath the oil pan and |

| up. This will make it easier to do the plumbing from the compressor housing to the carburetor, the oil piping to and from the turbo, and it will also be right up there over the valve cover were it will still look cool. Okay, actually the main reason we want to move the turbocharger to the other side is because we have this really cool conic air filter that we found and it would just be really super neat to use it on something. | |
