Not long after I decided on the fact I wanted a '66 Dart, I decided I want to do forced induction. I went back and forth between putting an SRT-4 engine in the Dart as opposed to the 5.7 hemi I was set on. Now that I've exhausted every avenue of research on the 2.4L turbo, I've decided against it and will stick with the hemi, the road I was already halfway down as is. That said, the hemi in an early a-body is a VERY tight fit, I have only one possibility for shorty headers (outside of custom), and it's not even confirmed they will fit. The SRT-8 jeep headers will fit with a big chunk cut out of my motor mount but I'm not really interested in paying such high prices for factory exhaust manifolds that don't even fit. So... The hemi complicates going forced induction in a couple of ways, it can either be an outrageously expensive roots or twin screw supercharger, or an impossible to route turbo. All that said, I'm starting to consider a rear mount turbo. Can anyone advise on this? I'm going to attach some images of some of the ideas I have. Don't make fun of me, I know they're crudely drawn. Most of these images are borrowed from members with similar (further along) builds as mine(Tincup, Rjsjea, etc.), or product images from various websites. I will be running megasquirt and want to utilize e85 with a flex fuel sensor.
These images were drawn before I looked at my engine today and confirmed that the hotside definitely will not be able to go up where I wanted to run it. both the oil filter, with 45* adapter or not, as well as the alternator are too far in the way and the shock tower is just too close to the engine to have any room. That really only leaves me the option of running the pipe under the passengers side steering rack boot and then up to the turbo which would be mounted into the inner fender somewhat at the top/front/side. I'll try and make a drawing to explain what I'm saying.
Image 1 shows the oil pan I intend to use, a jeep factory pan. Routing of driver's side exhaust to passenger's side via front under the pan up by the rack.
Image 2 is just a view of the shorty headers that *might* fit, maybe...
Image 3 is another view of the crossover pipe routed up on the passenger's side which won't fit. Imagine it run under (ground clearance is a concern) the passengers side steering boot and k-frame.
Image 4 is the y-pipe, also routed up but it kinda looks like it's headed to the steering boot anyhow, so much for 3-d drawing a y-pipe! :sad1:
Update:
Image 5 is an example of the routing of the hotside up to the inlet after passing under the steering rack.
Image 6 is the downpipe, looks to be like I can only fit about 3.5" at the very most here... Thinking this may be a problem...
Image 7 shows possible routing of the cold air intake...
