Fortunately d-serious blessed me with some extra gaskets when he was doing a production run. If you can’t figure anything else out, I can scan the gaskets with a ruler and maybe you can extrapolate the correct dimensions.
 
Wow, this thread brings up so many memories. I could have saved you a hell of a lot of time and effort but I stopped frequenting this site several years ago.

Im still here rocking my W2A intercooled JRSC setup in my CRX. Lots of custom parts involved.

i sold my spare D16 JRSC kit years ago on eBay for roughly $1200. Wish I would have taken the time to get a little more for it. Haven’t seen such a complete setup for sale in many many years.

Anyway, glad to see that there’s still some interest in this setup. Most people have long abandoned it and gone to turbo

Here are my dyno graphs. W2A intercooled JRSC D16A6. All internals, endyn head, yada yada yada. Mustang dyno. The AFRs weren’t completely dialed in at that point but now they are.

Yeah, I would have loved to see bigger numbers but the torque curve is great and the quaife LSD makes it a ton of fun to drive in a 2100lb CRX.

tune it leaner…somewhere in the 13’s and perhaps the 12’s at peak RPMs. You’ll make more power and if you’ve built a good det can and tuned the ignition tables correctly, there won’t be any issues.
 
Thanks for that clarification!!
I spent a lot of time reading your posts.

So were you able to use the stock crank pulley and alternator mount for your CRX install?
On an A6 you can and should use the stock crank pulley or a Z6 crank pulley. You should also use the OEM lower alternator bracket. I assume you know about the pulley spacing differences between the A6/Z6 and the Y7/Y8?

I use a Z6 crank pulley and I had a custom lower alternator bracket made that lowered the alternator down a bit. The custom W2A intercooler manifold that I use sits pretty darn close to the Denso A6 alternator so I had a customer bracket made. I could have used the stock lower alternator bracket but the alternator terminal would have been butted up against the bottom of the manifold and only insulated by the rubber cap.
 
The modified lower alternator bracket that came with the D16y7/y8 kits was simply a modified OEM lower bracket that was shaved to accommodate the offset of the 3-rib y7/y8 supercharger pulley. What you posted is not the modified OEM bracket.

The oil quantity for the 3rd generation Eaton M45 is 146ML. This info was provided to me via email by Thomas Stevens from Magnuson in October 2013.

Good write up though, I like that you are helping to spread this information.
