got my hands on a FC3S Silicon Radiator hose kit for $495.00 but because the rad is too thick, it needed cutting to fit properly. Next step rearend bushings, I find i putting it off too long, also stepping up to the thicker Series 5 rear sway bar.

ok so finally decided to work on my rear end. The goal was to poly fill some of the existing bushings and also install what we had remaining from the Protane Bushing kit which was the rear C-Arm bushing.

First thing was to drop the entire rearend, so that's remove the exhaust, driveshaft, rear shocks and the main bolts

Image

Image

We did not want to drain any brake fluid so just tied the rear caliper to the shock. So first, we replaced the front diff mount which was busted clean (guess tooo much burnouts :oops: :oops: ) . What we realized is that once the two main diff mounts are weak, the front diff mount will tear. So we got our hands on liquid urethane (thanks to miggy 8-) ) and filled these mounts also the mounts holding the rear end.

Image

Next we changed out the rear C-Arm Bushing to one from my Protane poly kit.

(Oh I sell these Protane FC3S RX-7 bushing kits - $1300.00 so if anybody want)

When we were done, left the liquid urethane to dry for a day and put the rear end back up with the new Series 5 rear sway bar. Will take pics of that later.

NEXT : Time to make the girl kinda sexy......... :D :D

Really interested in this specific part of your build.

Should help me understand a weird issue that's been hard to pinpoint

Check sumn, you ever changed your lateral link bars?

I changed back bushings and still hearing some squeaking, put it on a ramp and checked and seems like the lateral link joints is the issue

You have?

The links come complete or separated?

Not trying to spam the thread :) just that the rear end work really relevant right now :)

Can't guarantee they are good

All of the suspension being addressed is next priority in the list

I wondered about the link bar rubbers but hadn't completely ruled out the shocks

It's a weird squeaking...very annoying

Will jack it up soon and verify

ok ppl by surprise, and I was not even looking for it I got the legendary Knight Sports RF320 Turbo. Now if you remember I have the Knight Sports 4-beat ECU that works at .9 bar (12.7psi). This turbo is MADE for this ECU and set at .9!! i even removed my boost controller, don't need it anymore. the car is crazy and i think i good with the power output. NOW
I ready to do body work, I only putting it off yes!

The turbo was a direct bolt in with just the turbo intake piping had to do over to 2.75" from 2" because of the larger compressor wheel and housing.

Looks like the car going to be a T&T knight sports car lol 8-)

absolutely stunning....loving the KS turbo and matching ecu combo!


what rear struts and springs are you using? my sa22c has fc turboII ir suspension grafted on and the front is converted as well to fc. fronts have tein adjustable coils and rear has fixed height, damper adjustable ohlins shock+springs. i want to upgrade as well and your direction seems to be as good as i'd aim for. need to make the suspension faster than the car!

Well it's Tokico Illuminas and Intrax lowering springs. The problem with putting FC suspension on a SA is the weight of the car is too light for the shocks you bounce around a lot plus even with the coilovers you don get good camber adjustment.

If I had to do a FB/SA I would use first gen Tokico HP or Illumina with a good lowering spring (racing beat etc.) with the RE-SPEED hub adaptors to use FC brakes. They have for the front and rear. They used to have for only GSL-SE but now I believe you can get for GSL as well.

Using a Glowshift pod that fits directly in a DIN (deck space) i fit the 3 where the AC vents were facing slightly right towards me.
