Found a  nice option for replacing those urethane spacers. 1" aluminum spacers by 'QA1'. Got them through Summit racing. I'm going to get the struts assembled in the next week or so. Need ball joints! Get those bits in and I can pop them in the car!

I'm junking my previous MR2, parts will be transferred to this one though. The front and rear motor mounts have urethane inserts, they're moving to the new car. The HKS exhaust will find a new home in the new car. The speedo cable as well. Next few weeks.

And for the new parts! I decided to give these a shot. T3, Techno Toy Tuning camber plates. The plates look pretty good! Then they had an offering of some upper perches that have thrust bearings to reduce the friction when turning. seems like a good concept, let's see how they do.
pic 1 camber plates
pic 2 the upper perches. 1 set has been 'exploded' to show the various parts. the washer closest the perch goes into the perch as a load bearing surface, it's harder than the aluminum. Then the thrust bearing and upper washer.

On with the plans and related parts.
I have my struts out of a previous car. Need to clean them up and do a few little things. The GC springs came with a sleeve that was a tad short, so at the highest setting the car was 2 1/2" lower than stock. Either I need to use a weld on perch or get a longer sleeve. I was using a urethane bushing to gat a bit more height. The bushing did well enough though.
Pic 1 the struts as they are now
pic 2 the sleeves can be about an inch longer
pic 3 the urethane bushing, strut bushing from a VW Cabriolet, 1987.

Thank you for joining and for posting. Really cool stuff you've got going on! I will check out your build threads in a bit-

Mid 14-sec at > 13 psi? Need more rear tires?

No, it needs better breathing on the exhaust side.   A cheap header, crushed exhaust bends, 6 feet of pipe between the head and the turbo, a catalytic converter and a street muffler all add up to high exhaust backpressure.  I have already had to upgrade my valvesprings because backpressure was opening my exhaust valves.  HP peaks at 6000 rpm, instead of 7600 or so where the 20v should.  I'm convinced it's because of backpressure.  Midrange is pretty good. :)

I'm not going to upgrade it because it is quick enough, quiet and would just break parts with more power.

Wow,  I think this thread was made just for me.

Here's a pic of my twincharged, 20 valve 4ag AE86,

Here's a pic or two of of my compound turbo 1JZ AE86.

Yes, twincharging works...  I get boost in the white car as soon as the supercharger kicks on at 75% throttle, and then the turbo spools up extremely quickly when the supercharger is on.  The datalogs show 19 psi at 4000 rpm

It runs mid-14 second 1/4 mile times, and is only 1/2 second slower than the 1JZ car when it had stock turbos.

The blue car runs, but has not been to a track with the big turbos yet.  When the car was almost finished, both tracks by me closed.  I had nowhere to run it.  One has opened up again, so I'm working on it again.  More electronic stuff to do, eventually it will get to a track.

I'm hoping to get boost from the small turbo at low speeds, then both at high speed.

If that doesn't work, there's a nitrous bottle in the trunk.
