Yeah, firewall "shelves" just need to be shaved a little bit for fuel filter and thermostat housing clearance.
Well that's not good for me. NASA TT4 rules do not allow firewall/floorpan modifications. That would require a "non-production" penalty in TTU-TT3, which at that point I would just K-swap it, as that also requires non-production penalty due to the tubular subframe.

I think one could make the argument that they aren't actually part of the firewall, and you don't have to cut them completely off, just do a little bit of shaving.

It's possible, but it has it's own set of fitment and engineering issues. And the engines are pretty pricey.

Those don't work with the Ecotec Miata kit. The forged cranks on the LSJ/LNF have a different bolt pattern, so the flywheel adapter doesn't work. They also have an oil/water cooler built into the block that interferes with the "shelves" on the miata, so you would have to trim them.

Pick a better engine then. The only attractive thing for racing with the ecotec swap is if you have some weird ruleset that allows cross platform engine swaps but allows you to do whatever you want with tune and boltons with the stock internals and turbo. Then the LNF being able to do 400/400 on e85 with the stock turbo makes it like the only good engine choice for that class.

This is my plan so far for mine.
I've see one with that trans in the car, it wasn't finished but it looked like the shifter was in the right spot.the motor was also mounted way back in the engine compartment.
We are long overdue for an update... Here's the rundown of what has happened thus far. (TLDR: Car got way faster)
After we got the motor in the first time, I discovered a massive leak coming from the oil pan. So, out it came, and Joe and I spent an afternoon pulling the motor back out and scraping RTV so we could attempt to re-seal the pan.
Next we realized that the motor may have actually spun backwards, so I had to check the timing. Lord, I don't know how many times I had to spin this thing around to get these marks to line up, but I was elated when they finally did. Not pictured: the bottom mark (it lines up, I promise).
The next step was to wire the thing up. I decided to push the easy button on this and bought a standalone harness from Alpha Fab in Michigan (great guys to deal with, btw). Ugh, what a mess of stuff.
But, now the fluids are added and she's ready to fire! Here's a short video of it running open header.
Once I knew it ran, it was time to clean up that rats nest of wire and hose. Oh, and get the exhaust work done too.
Next thing to tackle was mounting the GM E39 ECU. On the non-direct injection motors' ECU, this is pretty simple, as GM decided to give you some holes that you could run some screws through. On the E39, however, no such luck. 3D printer back to the rescue!
Yep, it's also held in with zip ties... I'll probably change that in the future.
Next came the bracket for the AFR gauge... also, you guessed it, 3D printed. It also holds 2 switches. One turns on the gauge/wide band O2.
The other switch turns on this...
The rear mounted MR-S power steering unit. I really tried to find a place up front for it, but it just wasn't going to happen. 10 extra credit points to whoever can guess what the mounting brackets are made of and how long those hydraulic hoses are. I thought it would make those eventual 275 A7s a lot easier to deal with on course. Joe thought I was just being a weenie.
Hose routing is super tight.
Swap is done. I need to get you guys some running and driving videos. Hopefully this winter is the time for aero.
Here's the results from last weekend's autocross. I managed to place 16th out of 80 raw, and just under 2 tenths out of first place in class.
No idea what the mounting brackets are made from but your lines are 11' 6". Does the MR-S pump not fit where the jack went like the volvo pump I used does?
I'll give somebody else a shot at the brackets, and you're short on the line length. The MR-S pump probably would have fit there, but I figured it would help my weight distribution a little more with that placement. I'll probably put the car on scales to optimize its location.
