Struggling with all of this fitment, but I've been making some solid progress.

 

Slowly but surely making more progress on the exhaust. Finally found a use for the old s2k valve springs when mounting the muffler.

 

Getting ready to make all my AN lines this weekend. Here's a shitty diagram with all the fittings and adapters. If anyone needs part numbers for anything just let me know.

 

Just found googles version of visio (draw.io) and holy **** is it so much nicer to use.

 

I'm also in the process of designing the adapter from the s2000 driveshaft to the miata diff. Running through the analysis now for weight optimization. Currently at just under 4lbs in mild steel.

 

I wonder if an s2000 diff would fit in a miata msm carrier....then you could use a shortened s2k driveshaft and skip the adapter.

Bolt pattern is probably different.

 

Currently the driveshaft is 3" too short and the bolt patterns are vastly different as you can see. If I didn't have the OS Giken diff in the car currently, I'd probably try to swap in the s2k diff thats sitting on the floor although I'm not familiar with the msm carrier. Currently hoping to sell that though.

 

The MSM and s2k diffs share guts. So MSM axles would fit in an S2k diff.

 

Ah, I see. In that case, that could've driven placement of the trans and motor via driveshaft length instead of just where I wanted the trans.

 

While I decide between the cost of making a new driveshaft vs. having that adapter machined I found time to finish the muffler and downpipe. I should be finishing the wastegate mounting this weekend and the intercooler mounting over the weekend.

 

I wonder how loud this will be inside the car. I wonder how loud it'd be if you simply used a metal substrate cat as an exhaust. Tighter form factor. Ok, maybe
not radially.

I want twin scroll so bad. I want honda motor so bad. I want lots of things so bad.

 

I can only imagine this being loud for the passenger soooooo not my problem haha hopefully I can make a lot of progress this weekend and move on to wiring so I can start this thing.

 

Got the fender mounted up and it sticks out pretty far..... may or may not look okay.

 

Time to start bringing a tire sprayer for that right front tire...

 

It's finally ******* fits!!! I was able to make a quick fixture at home to place the wastegate flange and fit up at work. I'll have this all welded up tomorrow and I can move on to the intercooler mounting since that came in.

 

It was a pain in the *** to weld this and it warped just a little bit so a final adjustment after work today and the manifold will finally be complete. I will also be making some parts to mount the intercooler today.

 

Intercooler is all mounted up.

 

It's been a while since my last post, but I'm back working on the car after stepping away to run my LeMon's/ChumpCar teams first race in April. Just made the beefiest LS coil mount you've ever seen to mount them under the dash. I also decided to redo all my MS wiring instead of splicing in the s2k **** so I bought new MS 10' harnesses. I recently scored a BOV for cheap and picked up and EBC solenoid. Trying to get this finished up here soon!

 

A custom driveshaft was too expensive so I went the adapter route and had this made. Waiting to get it electroless nickel coated.

 

Just thought I'd give an update. I've had a bunch of issues reading in the cam and crank signals correctly with MS3x, but I think I finally figured it out after grinding some teeth off of the cam wheel. Intercooler pipes are done, they were super simple. The cadillac escalade radiator hose also came in clutch again for the upper hose. Just about ready to start it up. Also found some good stuff in the scrap bin for a front undertray/diffuser.
