Question for you guys, like an idiot I added the FM Coil Bracket adapter that does not fit the VVT engine because of the VVT line. Has anyone simply modified the VVT line to use AN lines instead of the hard lines? That way I could relocate the VVT line out of the way, and use the pretty FM coil bracket.

But good news is I've decided to just bite the bullet and go with a COP system from Fab9 (or LS coils). Might as well just do it right anyways. Also the VVT motor is in the car on Blackbird Fabworx Drop Mounts. Took about 30 minutes to drop in. Also with the help of Greg @ Thecarpassionchannel I created a new injection harness with the VVT power + signal pigtail built in. I think it turned out really well and looks better than OEM tbh.

I've got a few PM's saying the same thing. That certainly seems to be the prevailing wisdom around here (that LS coils are way better). Is there a main benefit of LS coils over the Fab9 system for low boost (less than 12 PSI) setups?
*Edit* Maybe it's better that I just figure out a way to mount my old ignition system. Get the car running as-is and then figure out an ignition solution.

So after doing some research, I'm gonna hold off on ignition for now. I'll be cutting, drilling and tapping the VVT ports for a 1/8 NPT to -4AN line so that I can move the VVT line where ever I want as seen here: https://www.miataturbo.net/build-thr...5/#post1437790
This seems to be a good idea for those not wanting to mess with the ignition system but they don't want some wonky homemade coil bracket. I'll DIY an LS coil setup if I run into ignition problems down the line.
*EDIT* The best thing about this place is people will call out your stupid ideas. I need to be called a dumbass, and people do that here on the daily. That's why I love this place.

So what are you guys using for exhaust setups? I've decided to go with a 01-05 Racing Beat Header (since I'm doing a Rotrex install down the line) with a 90-97 Yonaka cat-back. I currently have a test pipe for a 90-93 but obviously that won't bolt up to the 01-05 Racing Beat header. Should I simply take it to an exhaust shop and say "hey, please connect these pipes without cutting the flanges off?" Does anyone else have a more elegant solution?

From OBD2, 1.8L's, VTPS, ABS in more cars, Torsen LSD's, better synchro's in the 5-spds, much better aero, better tophats that increase travel etc. I could go on and on. There's just a huge list of improvements that makes the early cars objectively worse. But like all stupid folks, the lure of a cheap price and the thought that it will be easy to change all that won me over.

When I did my swap, I still had the stock 1.6 exhaust on the car, so I was essentially starting from scratch.
To save some $$ at swap time, I used the stock VVT header and downpipe, and fabricated from there back with a 2.5" pipe, universal cat, resonator, and muffler. Got most of it from Summit, and it wasn't overly expensive. I recently obtained an NB2 Racing Beat header which bolted right up to my 'NB' exhaust...

Tis a sad day indeed. Attempted my first start: Car cranks but does not fire. Composite log attached. I have sync counter loses.
Lots of variables at stake here. Car's been sitting for weeks. It's cold, I'm on full E85, and the battery could be low on power (on a trickle charger right now)
