My never been done before 84
Well before everybody screams in horror. I always wanted a 1st gen. (had a FC since 91). I picked up a 84 s for a $100 with very dead engine.
Yes that is a WC T5 out of a v8 camaro..
And before you all go ape crazy.. Mazda does not make 12a rotor housing anymore.. Don't get me wrong I love rotary engines. I just did not see the point of re-building an engine that only one manufacture makes parts for just stopped production.
Since it is a v6 (GM 4.3 that has been "modified") it fits really well.
Right mount
Left Mount
Cross member modified and powered coated.

Decided to paint the block black.. chevy orange just looked fugly.
From this pic you can see how only the water pump and harmonic balancer is just barley forward of the axle canter line.
The upper plenum will be modified. The throttle body will be rotated 180° angled down from the thermostat housing 5° and angled to the right 10°. This will give me ample clearance with out modifying the hood..
Fuel system. an-6 feed and return, a-1000 -6 pressure regulator, Bosch 0580254910 195L/Hr at 3.0bar (130 @ 5bar). Fram G3727 Fuel filter, very common on 90's+ Gm autos, Earls 991955 16x1.5mm (saginaw fitting) to an -6 for the G3727 filter, Russell 640913 12mm to an-6 banjo fitting for fuel pump, Various -6 / -8 fittings, stock fuel pump mount (it will be modified to mount the hi pressure pump)
-8 push loc hose, -6 push lock hose (Aeroquip)

The GLS rear axle that was modified. Not in pics is the 3.636 Ring and pinion that I got out of a early 80's 626 5sd car.
All cleaned up and Painted. Third link mount added. Panhard mount and cross brace, upper mounts cut off. Lower mounting points dropped down 7/8". Stock spring mounts cut off and replaced with moser 5" spring perches.
Cleaned and painted brake backing plates with new axle bearings/retainers.
Third link box welded in with 18ga sheet metal, primed, seam sealed, painted and under coated.
From under the car
The pre-emptive rust abatement. This is a very common rust area on 1st gens. I had no signs of rust until I removed the reinforcement plates from the wheel wells.
Reinforcement plate welded back in. Primed, still needs seam sealer,paint and truck bead coating.

Exhaust header flanges, 3/8" thick cut with a plasma cutter.
Bolted up to a spare cylinder head.
Merge collectors from Cone Engineering (do a web search for them, they have a ton of stuff)
Exhaust system is 1 5/8" x 36" headers collected to 2 1/4". The duel 2 1/4" will be merged into a single 3" after the transmission. Magnaflow 5"x11" with a 22" case. I don't want it to be to loud.
I have a lot more pics. just click on any one and it will take you to my webshots..

Thanks for the positive comments. More love for keeping an FB alive here then other forums.
I forgot to mention that the area under the wheel well reinforcement plates was primed with rustoleum cold galvanization primer (It welds through really well). The white primer is Rustoleum clean metal primer.

Now w/ 12A SP
iTrader: (3)
Though seeing a 13b would be great, the 4.3 looks to fit in the fb engine bay pretty well, almost where the 12a sits. Your fab skills are great as well so it looks great too. I thinks its great you went v6 instead of small block, oughta save some weight on that and just on outward appearance it looks like you've done some work. if you don't mind me asking what do you have done I see efi and intake, how about, cam, roller rockers, valves, compression? Forgive me if it's been answered but, my curiosity is getting the best of me on how you've speced this power plant. Pretty creative though I must say.

The engine is built for a very strong mid range iirc 2,000 to 5,800 rpm and will nose over at about 6,400. The T5 trans is out of a v8 camaro IIRC 2.95 1st and a .63 5th, combined with the 3.636 Ring and pinion is a good match for the rpm/power..

I just looked up some specs when I ran it on a dyno with a 650 holley 4150 and a marine points distributer 16° at idle 32° by 3,400rpm.
max torque was 342 ft/lb @ 4520rpm Max Hp was 334 @ 5,800rpm fell to 323 by 6,500
funny thing is it was making 315ft/lb @2,200rpm.. and a 152hp by 2,500rpm..
It had non optimal small 1.5" headers on the dyno. I don't know if I will gain any more hp with EFI but throttle response should improve as well as drive-ability.

82, 83, 88, 82 RX-7again!
Awesome job with that car - I am thinking I have parts to redo my 12a but I really do question whether I want to go with a 4 or 6 with more power, better support (parts) and gas mileage (ha, i don't care about mpg - 3K miles in 6 years).
Best of luck with that beast.
