FD #6 "build" - combining two cars into one
i have been quite busy the last couple months.
i finished my SC300 / 1jz VVTi swap a few months prior, tracked it, and decided it wasnt worth the extra investment to make it "fun" (5spd swap and torsen LSD). i decided to sell this vehicle (it still hasnt sold) and get another FD.
i recently reconnected with an old friend who owned a 94 salvage title MB touring for 4-5 years, and he had purchased it from my childhood friend (basically my brother). back in ~2004 my childhood friend and his dad purchased an off-shelf Atkins 3mm engine (with new housings, NEW irons, lots of new parts) and installed it into the salvage car along with a powerFC and datalogit. i inquired about buying this old car i'd been familiar with since about 2004, and i ended up buying it. the shell was in pretty rough shape, but it had this very good powertrain, decent (complete) 94 interior, good tan seats, and many other sellable parts i wasnt interested in keeping (glass roof, greddy FMIC, EBC, etc.)
so, knowing the powertrain was good in this salvage title car, i wanted to "start over" with a clean title roller, which i discovered here https://www.rx7club.com/3rd-generati...oller-1102723/ and noticed that jim thompson had already locked it in and beat me to it!! so, i talked to jim a bit (great guy, btw), and i ended up buying the roller from him (complete exterior, dash, plus a few interior parts, stock wheels, etc.) for a good price.
this roller is a black on black base model, which i wanted particularly for the hard top. 7-8 years ago i had a base model FD that literally weighed 2660 on the scale with 1/4 tank of gas. i wanted to get back to this lighter weight, more headroom RX7. black isn't my first choice, but it's good.
i've taken a lot of extra time to make sure things are as clean as they can be without being extremely time consuming, and i am pleased with the results. i also ended up having to do some fixing, of the heater box for example, which had a broken heater air mix door, which you'll see in the pictures.
summary of what i've done so far:
swapped over front harness (total pain in the ***, btw)
swapped over engine/trans
swapped over front subframe and suspension
swapped over ac blower
swapped over AC evap
fixed heater/mix box
swapped over heater/mix box
swapped over door handles
swapped over steering rack and lock cylinder
pressure washed new (used) black carpet
installed carpet
soda blasted pedals and various engine bay tubes/brackets
swapped over pedals (clutch, brake, throttle)
swapped over tubes/brackets in engine bay
what's left to do: (i'll be posting pictures of all this in the next couple weeks)
install differential (new axle seals installed)
install low mileage axles
install PPF
install new brakes
install interior (headliner, 1/4 panels, door panels, bins, rear plastics)
install door/hatch weather stripping
install fenders
install powerFC and attempt first start up after all this work
so, on to the pictures, which are in somewhat chronological order, but not exactly.
salvage title car when i got it home
some strange stuff on the salvage car (aftermarket carpet installed on top of tan carpet which was left only in the front 1/2 of the cabin)
bolts missing from dash mount points

more work from last night, (installing diff, powerplant frame, axles, and driveshaft)
nice pic of how clean this car is
i had to lift the diff with my floor jack because i was working alone.
floor jack didnt get it QUITE high enough to slide the diff mount bolts through, so i had to add a 2x4 to get it into place
axles in
all complete (except i can't find the damn driveshaft bolts!)

Base model car looks super clean underneath alright..... what's up with those toe links though? Yikes.
Dude, if I don't see pics of Jeffy in this thread soon I'm going to lock this thread down

i repaired my door trim piece that rides along the bottom of my window. well, i didn't "repair" it, but i modded it to keep it in place...
reman calipers (front) installed
new brake lines (front) installed
new rotors installed (rear)
shifter turret installed
shifter installed with new rubber
filled trans and diff with fresh mobil 1 synthetic gear oil. this new "gravity" way of gear oil filling was much easier. i should have tried this years ago.

update here:
I've had an electrical issue with the gauge cluster (bright light indicator staying on constantly, oil pressure gauge not working but pegging top and bottom with the lights on and off, charge signal not being sent to the alternator, warning lights not lighting up at KEY ON... etc.) so I pulled the dash and have been doing some troubleshooting while I've had enough energy.
I got sick about 2 weeks ago with two issues and have had very little energy, waiting for a test to figure out the second issue, but I am almost healed! I had enough energy the last two nights to troubleshoot some wires. I also wanted to verify that each harness (dash, firewall, and front) is 1994, which they are. that's good news.
so here's where i'm at:
dash back out
missing the small harness that connects this little green wire plug to the fuse box and dome light area. luckily i'm getting one from jim Thompson Monday.
this end plugs into the fuse box
and here's a pic of some wire tracing I've been doing. all wiring appears to be correct on the car, and it's looking like something is wrong with the gauge cluster.

Pics and more info on your Lexus SC build? Is it black?
My first build was a black SC. Pics of it in my thread (if you didn't already see) -- SC400 V8 Twin-turbo 6-spd, GS4 diff w/Tomei LSD, etc.

mine was a 99 sc300 i got and built to be a track car, but at the time didnt realize how prohibitively expensive the R154s (and even w58!) and supra LSDs have become... i tracked the car and was bored, so i decided to sell it and build an RX7 instead of sinking money into a LSD and 5spd swap for the lexus.

it was basically a stock soarer 1jz VVTI engine that was in great shape and was super quiet.

also, rx7 update: i swapped clusters with a friend's 93, and all wiring issues went away. SO MUCH TIME AND THINKING WASTED, but at least i know now
i'm going to attempt to combine two clusters into one.
a friend is donating one with a bad speedo unit. does anyone know how much the speedo/odo circuit has to do with the other functions of the cluster? i would hate to swap my speedo/odo into this different cluster just do find out my speedo/odo circuit is what was grounding out... at that point i guess i could use the wrong mileage speedo/odo unit and just swap the gauge faces to my 94.

well i havent updated in awhile. i had a health issue and was out of commission for a few weeks, but i'm back!!!
i left off with the electrical issue that ended up being a short on the gauge cluster flexi circuit board.
i picked up with starting a custom VMIC setup. i'm again going with a "value" setup that i think will actually work pretty damn well. i found some ebay sellers selling copies of the CX racing "rx7 vmic radiator". i picked one up for $170, and it is decent.
the radiator has brackets and threads to use the stock fans (but mounted on the "back" of the radiator) but as you may guess, being a $170 radiator, the brackets don't quite line up. they weren't very far off, so i was able to alter them and the fan decently, but it did require some work.
i then had to position the radiator and make some brackets to mount it. i think they turned out pretty well.

i've always had difficulty keeping IATs down at the track (i do plan on tracking this car) so i wanted to do something on this car to address that. because i'm on the stock twins i decided to go with the CX racing cold and intake box (aluminum copy of the M2 intake box). $300 on amazon.
as you can imagine, again, the quality isn't amazing, but decent. the bottom intake area wouldn't work with my custom radiator setup, so i had to alter that with my saw, and i got it to fit pretty well with the new setup. this box will be pulling air from the middle of the "V" and i think it will work very nicely. the piping included with the kit (including the small 90* 2 bolt flange pipe for the primary turbo) fit very nicely.
here it is mounted up and altered, and you can check out my sweet lack-of-intercooler loop until i mock up the intercooler portion. i'll be tackling that this weekend.
^i'll be using the generic SMIC upgrade intercooler we've all seen around (XS power i think made a lot of these) flipped over into a V setup. the main reason i'm using this is because of the size. i have 18.5" to work with (including 51R battery and intake box).
i also had to purchase two small K&N air filters to go with the intake, $30 each. i dont have any pics of them so far. K&N RD-0720

another update from some wiring work tonight:
for some reason a previous owner of my donor car hard-wired the passenger side headlight motor to the front harness: *I don't know*
but each wire was soldered (and brittle) and electrical taped.
knowing i'd never be able to find the correct mazda plug without (probably) buying at least a headlight motor, I decided to use my own connector.
and got it tucked away fairly well away from harm and destruction

I love your "budget" builds mostly because I had the same mentality as you. Order a cheap part knowing it does 95% of the function for less cost, but requires a little more fab work than the normal rx7 guy.
I am waiting for the single turbo build as soon as those twins start puking oil

Thanks! The main issue with VMICs is the cost of all the fab work. The coolers aren't much different. If you can make your own "kits" for things like this you can save a lot of money. I've been able to do quite a bit with my projects without having a welder, but I can handle quite a bit of cutting and bending in my garage. In this case I was able to buy a pre-made intercooler and cold air box. I simply had to make some brackets and do some alteration/cutting.
These are 99 twins with about 20k miles on them, actually functioning sequentially, so you may be waiting awhile!
theres a better chance of me going single because I'm bored
