Can you take a measurement on the Volt fans? Just the shrouded portion, not all the extra bracket stuff, please.

I considered getting Volt fans, but the 600w C7Z fan is also a spal brushless and only like $220 brand new OE Delco on rock auto. It's about an inch thicker than my dual Contour fans.

I will get some measurements this weekend.  :)

Also, this was easier than I expected.  My goal for Sunday night was to have the engine/trans out.  I'm well ahead of that schedule..

So. Cool.


Ever since Craig did his swap, it's been in high on the desirable swaps list. Progressing nicely dude!

Modified the subframe for C6 poly engine mounts:







And, mocked up on the subframe:







And mocked up in the engine bay.  The engine angle is off slightly here, but is sorted out now.  I've got a start on the cardboard based CAD, once that's done, I'll draw them up in CAD (computer style) then get them laser cut, then bent/welded/painted.   The concept on the mounts is to set them up with the engine as far forward and low as possible, then I can shim up/slide it back as needed.

Excuse me but you literally just get to bolt the engine into the car with the factory subframe?  That's awesome!

That really is amazing that it drops in so well.
Granted, there's a long way to go, but that just looks like such a great fit. 8)

Well, sorta.  Haha.

I had to hack a crossbar out of the subframe.   The nice thing is Aston cast the subframe in two pieces and welded in aluminum tube across them to make the subframe.  I'm able to cut out the tube without going all the way back to the cast, meaning I get to weld the new bracing to aluminum tube, not nasty oil soaked cast aluminum.

The factory crossbar is 3/16" (err, 5 mm) 80mm x 40mm or so tubing in the area I cut off.   The dry sump oil pan is too deep too far forward to clear it.   So I'm going to put in a piece of 1/2" aluminum and plate the open ends.   I'll also have to clearance the subframe for the driver side header and a little bit for the dry sump lines, but not too bad.   Here's the piece I'm using to reinforce the subframe;  I just drew it up quickly in CAD and am having it cut by SendCutSend.  I could do it myself, but for their prices, it's only slightly more than me buying the aluminum, and much less work.



Beyond that, I had to drill out the factory Aston engine mount holes slightly to fit the C6 mounts (those are from Hinson Motorsports, funnily enough) and clearance one area by about 1/8" to fit them.   The OEM engine mounts from Aston would have worked, but they're huge, and fluid filled, and expensive.   Also not particularly firm, so these should be a good all around balance.  Beyond that, I'm just making the actual pieces from the block to mount, which will be very similar to the Ronin pieces for an FC swap.

Fitment is TIGHT front/rear and side/side.   I need to make sure my alternator will fit, or find an alternate solution, as it's very close to the strut tower.   The crank pulley is spaced exactly one "I can fit a belt through this tiny gap" away from the rack, and I have to pull the factory sound deadening off the firewall to clear the rearmost cylinder head/rocker cover, but it will clear.   The rest is pretty easy to deal with, and there is sufficient room up/down to clear.  It should fit the larger supercharger lid as well, which I do plan to add eventually.

The transmission will require cutting a crossbar out of the rear subframe.  It will fit with it in place, but will SUCK to install/remove.  So I'll cut that out and put some interlocking tube clamps for a rollbar in place so that I can easily add/remove the car when I need to service things.   The torque tube should "just fit" in the tunnel, but I do need to shorten it, and do a bunch of clearancing on the transmission side to tuck it in tightly.

I'm planning to keep the diff and trans coolers, pull the factory trans cooler out of the Aston, and put in smaller coolers side by side in the same spot, one for the diff, and one for the transmission.   Since they have pumps installed from GM, it seems a waste not to use them.

On the engine, I obviously have the dry sump stuff, which I'm running to a Peterson dry sump tank, and probably a custom catch can/vent system.   For oil cooling I'm ditching the stock stuff, and using an Improved Racing thermostatic unit in its place, as it's vasty more compact.   I'll put a big oil cooler up front, along with all of the other coolers (radiator, AC condenser, supercharger heat exchanger, power steering cooler).   There is a lot of real estate up front for coolers, at least compared to what I'm used to with RX7s and the Mustang.  Probably 18-24" total front/rear.   My intention is to go AN fittings for all of it, mostly for future servicing.   I can keep the factory power steering cooler, so that's something.  LOL

Got a chance at lunch to draw up the mounts.   My process is:

1. Make flanges out of paper (it's easier to use a dirty finger to mark the holes/edges)
2. Make mounts out of cardboard (transfer flanges from step 1 to these)
3. Set mounts flat with a good ruler for reference (I design in metric, so I use a metric ruler).
4. Take pictures with straight on aspect ratio (your iPhone can help with this)
5. Import into Fusion as a canvas.
6. Scale canvas based on reference.
7. Sketch around design.  Adjust known references (bolt hole sizes, bolt patterns).
8. Extrude/adjust as needed.
9. Export sketch as DXF for laser cutting.
10. Bend/cut/weld as needed.

In the first picture you can see my reference canvas.   In the second, the parts with the canvas hidden.   The little "rectangles" are cuts for bending points.  Once I bend it all up, I'll weld those in.   These will be 1/4" plate, and they do have reinforcements that I don't have pictures of yet.  :)

I am surprised you draw in metric,  I work with a bunch of toolmakers so we design everything in inches.  are you going to gusset the mounts?

I got into the habit from doing 3d printing, where a lot of stuff was metric, now it's just habit.

I do have gussets being made.   This is what they look like.  There are 2x per mount.

Looking good Blake.

I don't do anything that sophisticated, but I really should get used to using metric for everything.
It really is simpler, and if I can get it in my head to always use it, it should simplify things too.

The nice thing about putting DRO's on my lathe and mill is they have metric modes too.
I just need to replace all my indicators with metric.  $$$$

I work for a British company with Old School American machinists so I am constantly converting between the two units of measure.   I prefer metric but I still model in SI.

So, I've hit my first issue (knew there would be at least a few).

My alternator doesn't fit.   The strut tower conflicts with it.

Immediate solution is to buy the Holley accessory drive.  Well, a few pieces, I already had the power steering bits.  This will replace the water pump and put the alternator where the AC was.  It reverses rotation for the water pump, allowing me to re-route the belt and delete the "high point" factory alternator location (which is where Holley puts the AC).

I'm fairly sure the AC won't fit there either, but maybe... (it won't, but I'd like to lie to myself).   ASSuming it doesn't fit, I can hack up the Holley pump to delete the AC bracketing from the water pump, put the alternator in the low position, and just find a spot to stick the AC compressor.

9. Export sketch as DXF for laser cutting.
10. Bend/cut/weld as needed.

Any reason you wouldn't have SCS do the bending, too? Or do you have a decent bending setup. Anything above 1/8" I start to struggle with.

I wish we worked in metric, I'm sick of fractions.
