Don't forget your turbo exits to 5" on the hot side so you will need a reducer. :)

Oh wow, thanks Man! I was going to have to draw those to be able to program them, Now I can just work on CAM side of things...
I recognized the oil pedestal one and the other ones seems like its the bolt pattern from the BRE mani with a round hole for my throttle...am I correct? Thanks a million! Chris |

Like I said you're going to have to check up on the dimensions first before you cut anything. Oil pedestal is correct although you should probably weld some fittings directly onto to the iron base instead as it's a very very tight fit with the transmission line there(PITA). No the second plate is actually the MAF base(which is dimension correct) to weld to the filter intake. Trust me you do need the damn MAF, not only because you are using the stock tb but because without it the alternator doesn't charge the battery correctly(only like 10-11volts)/pretty fcuked up right? That was a bitch to find out!!! Is there anything else you need?
I will post some pics of the CAM process as well as the cutting...:) Chris |

Here is modeling for the other side...
The plan is to taper all 3 diameters into the 3.5" throttle hole from the other side and then make a cut that encompasses the areas where they meet so the flow is not disrupted through there. It isn't very clear in the simulation but it will make sense when you see the finished part. Cheers! Here is the drawing of the "common areas" between the RX-8 throttle and the 3 butterflies from the BRE throttle. Attachment 718146 We begin by tapering in the diameters Attachment 718147 Attachment 718148 Chamfer the backside profile... Attachment 718149 Attachment 718150 And then cut the common areas...

Just thinking maybe you should have opened up the intake manifold and removed all the separators since you're now going to use a single tb(PITA)?
|
Looking good!
Would love to see a ball mill in there though :nod: |
lots of work. would it be easier to have swapped chassis than motors?

not really, isn't that the point of a swap?
I'm putting more work into this than what is needed because I want to... It's part of the fun. I couldve done the swap with way less work but why? C

Put an hour or so into the Alternator pulley. I decided that I wanted to keep it in the stock location, from here, moving it forward is the only option. I settled on making an adapter bracket/spacer to move the Alternator fwd so it can be turned with the front crank pulley instead of the rear one as is stock. The only problem then would be that the front pulley is 19% bigger than the rear one which would mean the alternator would overspin so I started working on a 20% larger alternator pulley to slow it down to stock levels. Of course, while Im at it, I will mill a rotor shape into the front of it :D

Ok...at first when I was reading this thread it was looking like the average guy's RX8 conversion...then you busted out the CAD and water-jet cutting machine (don't know the real name...lol) and now I'm feeling ummm....betrayed lol. It doesn't mean I'm not in awe of the work...because I am...and I can't wait to see how this turns out!

where do you work mate ? I think you have some of my new favorite tools !!

Chris pulley came out great! If you ever make any in the stock size with the rotor then count me in for one! |
great build bro!

Decided to polish the face of the rotor on the pulley...the pics don't do it justice, had to put a pen in the picture for it to be noticed but it looks like a mirror in person. Has great contrast with the rest of the machined surfaces...:)

I finally got around to making the two holes for the Wastegates and tacking them on to check fitment. Now I need to verify everything fits in the engine bay and then pull everything out and finish welding the down pipe and the wastegate flanges.

Threw everything back in the car to check for wastegate and downpipe fitment and found that the wastegates were fine but the downpipe would be a bit of a problem. Essentially, I got it in there but it would be so close to everything that it would be nothing to but headaches and vibrating noises so I made marks in the problem areas and I pulled the DP off and "compressed" some of the areas in my big vise. The result is at least 1/2" of clearance everywhere and not so much loss in flow :)
In the process I also noticed that moving the alternator forward to use the front pulley while keeping in its general oem location would cause the front belt to interfere with the waterpump pulley...this means I will probably have to throw the alternator over to the driver's side (as in the last picture) regardless of my desire to keep it in the middle of the engine.

Worked on the wastegate Dump today...I still want to recirculate it back into the exhaust but for now will just dump it mid way. I am unsure if I will be able to package a reroute into the exhaust somewhere so this will work for now. I would like to add that that flex pipe, which is a necessary evil with this setup, is the hardest thing I have ever had to weld...it just wanted to melt away so the welds aren't pretty at all...Im just happy it sealed...lol I couldn't use a regular flexible section due to the available space.
