after posting a pic of my RX-4s together in my introduction thread, I thought I should give a little background on the rally car.
I got it fairly complete with a siezed RX-7 12A (dropped an apex which jammed between the rotor and housing) and burnt out clutch (tried to tow start with siezed engine) for a little wheeling and dealing, fitted up an old 13B I had in the shed from another deal.
been doing a little more work to it in the last couple weeks, now has my 48 IDA fitted, as well as a falcon alternator complete with charge cabling and fusible link box, and I finally got around to fitting some Bosch electronic ignition coils to replace the standard resistor coils they were using with the S2 electronic ignition (wrong coils), also fitted a 16" DC thermofan, but still need to rewire the ignition feed to tidy it up and finish wiring the thermo to start automatically.
it is still a work in progress, and I'll try to get some pics up of it soon, as of now the spec list reads like this:
1973 S1 (12A) RX-4 sedan
BODY:
bolt in 1/2 cage, seem welded and reinforced suspension mounts
SUSPENSION AND BRAKES:
all standard as far as I can tell.
DRIVELINE:
lightweight flywheel
sprung centre button clutch
S1 RX-7 gearbox (noisy, but awesome gearshift)
locked stock diff
ENGINE:
RX-4 type 13B, suspect E.P.
48 IDA weber
S2 electronic ignition with magna coils
2" short primary extractors into 2.5" system with single resonator and rotaflow style muffler
EXTRAS:
ford 80A alternator and EF falcon main fusible link box with modified wiring to suit
16" DC thermofan
twin alternator belts
TO DO:
reoplace LH headlight assembly
fabricate oil catch can and cold air induction with pod filter
bigger wheels and tyres
replace gearbox (anyone got a 121/RX-5 box they dont need??)
fit lower diff ratio (have 4.44 but would be nice to find a 4.8 from an old E1300)
I mioght not be able to get her out until next season as there are only a couple races left, but when I do I'll try to get some footage.
