Orange is the new Bamboo Tan

I've passed the point of no return. The L16 has been pulled out of the 510.

 

 

 

I've given the L20B a fresh coat of paint and installed the flywheel and clutch. This is a lightened stock flywheel. There were conveniently located holes around the outside of the flywheel, from the balancing process. I was able to slide a screw into one of these holes and brace it against another screw that I put in the alignment dowel hole, to keep the flywheel from spinning around while i torqued down the bolts.

 

 

 

I've installed the new throwout bearing.

 

 

And slotted and painted the 510 engine mounts, so it can sit about 1/4" lower.

I got the L20B installed, with a little help from a couple of friends. It slid in fairly easy with the transmission jacked up as high as it would go (before hitting the transmission tunnel in the body). Turns out I have an adjustable clutch slave cylinder, which should make it easy dialing in the perfect clutch action...

The little plate was for reinforcing the flex plate on automatic transmission cars. It also is good to use with an aluminum flywheel to keep the bolts from digging into the aluminum.

It goes between the bolts and the flex plate or flywheel, not under. The raised part indexes into the flexplate but would not fit under a flywheel well. It seems to have been jammed into the seal here, likely a big part of the leak and goop fix...

Left... this part clips over the end of the crankshaft then the flexplate, then the spacer on the right then the bolts. The raised part on the left part accepts the nose of the torque converter and besides supporting it, also aligns it with crankshaft center line.

 

Not used on manual transmissions.

Adjustable clutch slave means you need the spring too. The fork will have a hole in it at the end where the spring attaches and there will be a hole in the slave too.

You will also need the correct slave cylinder for the spring to attach to if you don’t have that. Like so. 

and spring looks like so

I've taken the 510 out for a few test runs, after getting all the other peripheral equipment attached the to the L20B. It fired up without much trouble, after a few cranks and a shot of starting fluid(that was probably unnecessary, if I had been more patient). I posted the first-start video on the Ratsun facebook group, for anyone interested. Overall, I'm pretty happy with the engine swap. I tried to keep a realistic expectation on what an additional 15 horsepower would feel like, and it just about hits the mark. I was a little worried how the lightened flywheel would feel, but it's nicely responsive. At about 18 pounds, it seems to hit the sweet spot, in my opinion. It was a fun challenge figuring out how to plumb the coolant through the intake manifold and back to the water pump, along with the thermostat bypass coolant line. I purchased small diameter silicone hosing that worked well for this purpose.

 

 

During the install, I also hooked up new Voltage, Temp, and Pressure gauges, and mounted them under the dash.

Installing hood struts was one of the last projects that I wanted to finish before the wintertime slow down. FYI, these are 80 pound struts. If I were to do it again, I would get slightly lighter rated struts, like 70 or 75 pound.
