While summer appears to be winding down as do the number of days that I’m willing to drive the car. It’s a double edged sword because the garage is still hot as hell but a fan helps.
So what has been going on? A lot of wiring,a lot of waiting for parts and time bending body panels. I decided to remake the firewall as the old one had a large hole from the factory miata fuse box. The new one is plain with minimal holes and several bc opponents mounted from the back side.
The wiring harnesses are all net new (minus the engine harness) and we’re made using txl wire and concentric twisting. My initial expectation was that it was hype but the results were true my magic! It is far more flexible than I ever expected. For connectors I went with deutch connectors besides for the fuel pump and fan (their connectors for 10GA was $$$)
The PDM install was next and I was able to get it mounted with space for the Hondata ecu. Wiring is a bit hectic but it should be fine and contained under the scuttle. One project that remains is an aluminum plate for the front of the dashboard to mount the wide and sensor and gauge cluster. With 2 rails for wiring management I am hopeful it will be easy to remove and install the scuttle without much fuss. As seems to be typical I have a whole host of ring terminals but none that are the right wire size or loop size..
I removed the body panels on the front,the scuttle, nose, hood, side panel, dashboard etc and then removed the exhaust exposing the engine.
Up next- we pulled the engine (Drain all of the fluids before ever pulling an engine..) and made a big mess. Shockingly it came out quite easily.
On the left- The ecotec engine. On the right- The Miata engine. (note the miata engine is on a pallet which lifts the height. The transmission on the ecotec is about 2″ shorter so the shifting location isn’t idea.
Anyone want a miata engine? I have a deal 🙂 94 Miata with about 80k on it.
Side by side View. Ecotec in the front.
New engine in.. Kinda! I had to cut out some trans tunnel bars. The engine is a bit wider and taller. Taller was expected. Wider not as much. There will need to be some modifications made to get this to work.. The fight isnt over!
After many months of collecting parts I believe I am finally in a position to start pulling the car apart in preparation for the engine swap. For those who haven’t seen or heard- I will be removing the Miata Engine and replacing it with a 2.0 GM Ecotec engine (with Turbocharger and direct injection..)
I will admit- I had a large amount of anxiety (and still do..) about pulling apart a car that was driving and running quite well. Especially not knowing if this new engine would fit or how many modifications are needed.
Starting with the seats, then the transmission tunnel, Radiator, scuttle and some sheet metal I started to pull off the covers and find things to remove- There certainly is no shortage.
The radiator was long overdue for a flushing, the seats had crap under them from 2010 and the questions continue. I also made the decision to remove the installed Halon Fire system and replace it with a single hand held unit in future. There are a few pounds I feel we can save!
Looking at all the wiring and I certainly think there is a good 40 or 50lbs of wiring that will be coming out of the already trimmed down harness
Mitch from Swap Time recently did a video about the harness. It is set to arrive on Wednesday of this week. Following that I will probably try find an hour or 2 to pull the engine this weekend and see if the new one fits!
There was a single show in 2018 left on the Calendar and foolishly I thought I would give it the royal treatment. I pulled many pieces off of the car, polished it with high speed buffers and turned my hands and face into a filthy mess.
Unfortunately the idea to wax the sheetmetal afterwards was a mistake. It left streaks and dulled the image. In future I wont be waxing the car… actually I have decided to wrap it after getting its new engine.
Surprisingly the trailer fenders really respond well to being polished. They shined like crazy! Who would have thought that a Galvanized boat trailer fender could look so good?
What started as a promising morning didn’t end very well. I pulled the motor mounts off of the engine and welded on the needed offset pieces. Things were going very well! (note the metal braces going forward is to prevent the engine from rocking)
Using the”custom bolts” needed for the flywheel I managed to get all 8 in place and hand tight. I’ll admit I don’t love that there is no locating pin on the flywheel because it allows all of the rotational torque to be transmitted through the bolts to the transmission.
This is what the bolt looks like. It’s an m11 -which isn’t something you can easily find and definitely not something Chevrolet dealers usually stock.
After hand tightening the bolts I grabbed the torque wrench and set to 20ft lbs I wanted to get everything started and check alignment.
The first bolt achieved 20lb fts but the next 2 appeared to strip out. At this point I stopped and removed all 8 bolts and inspected the damage.
Even though the bolts appear hardened they lost their threads quite easily. The crank was inspected and it is fine.
While not ideal I’ll give a few vendors a call on Monday and try sort it out. Unfortunately m11 is a very uncommon size so this won’t be easy
I placed an order in early May for a pcm wiring harness and flashed pcm. The company was Swap Specialties and Performance. ( http://swapspecialties.com ) Initially they told me 4 weeks turn around. As of this day it’s been roughly 13 weeks and they don’t answer their phone consistently (4 times in probably 40 calls) and when they have they told me “it’s being buttoned up and will go out Thursday”- but nothing has ever appeared. Then the story changed to “that person doesn’t work here anymore” but the line about it shipping on Thursday continues.
I finally filed a paypal case against them and not surprisingly they did not even reply to that. Thankfully Paypal was able to recover my money. ($730+). Their conduct was very poor and the multiple lies were not appreciated!
If nothing else I hope my frustration saves someone else the hassle. I will admit I don’t know what I will do next- this is a big setback.
