1980 Mazda RX7

[oldone]

And its powerplant,a conservative 230RWHP

[Tarka]

Aha, that explains why it sounded so nice as you rolled past us at the campsite on Saturday evening.

Have to say, all the cars you guys brought along were excellent. Really liked the little early 70s saloon (RX4?)

[MiniDan]

Thats fantastic

Was admiring it at the RR show on the Sunday ;D

Pity I didn't hear it going

[hongkongphooey]

Sweeeeet....i've seen that over on mazdarotaryclub.Mine's the white v plate series one gen one on there

[oldone]

Thank you so kindly for your comments.........ol 'Rusty' is not a show car but a 'go' car....had to move around slowly at RR as she can be noisey when woken up...as the BMW 330i and VW GTi drivers found out on the way to RR.... thank goodness she can move around on idle comfortably most of the time she is used mainly to test motors I build or run them in.......

Cool car, undecided about the wheels but that's just me. Just a warning, the link contains a few dots too many...

[oldone]

thanks bud,........when I put the Rx2 into storage,and needed wheels to put the 7 through MOT,I just swopped them and its become a permanant thing........got the period wheels,just have to clean and put new tyres on,then all will be sweet ;D

Its a habit of mine..........the dots..........that is............ ;D sorry................

Awesome motor in this sev. People just don't know what they're messing with! That is until you hoof it past them! ;D

[Lewis]

Loved the noise this made too - saw you rolling along in the morning at RR show, caught the characteristic 'brap, brap' coming

[Stiff]

Propper little pocket rockets these. And that engine looks fantastic!

[oldone]

thanks dude,the 1308cc can really get up and go if you dig your spurs in ;D

[Saru]

Nice!

I miss my 82 RX-7.

[oldone]

Been some time since I updated this thread,so here goes.

The brapper is in bits (nearly) So after I had finished porting a family members 12A intake,I was fully juiced and decided to start on the 'brappers' intake.The reason is that I could see where I had misjudged on the alignment of the ports on the gasket,not much but enough to pee me off As I was busy I also decided to change the flow angles inside the pipes don't know where I'm going with this idea,but if it works its going to be stonking Have not seen the intake ports for 2 years and I was quite surprised at their size Hoping to shake it all apart this weekend and letting the angle grinder fall on it ...................

[oldone]

Things never work out as planned.My motor is still in the car



however I have finished the IDA mods I've wanted to do for some time,the mods give me a few cc's more of fuel in the bowl.....








Will endevour to shake the motor out the car in the week and start some serious work.

[oldone]

So I shook the motor apart and found this



some very carbaned up rotors !!!!!!1

one very scored housing from an apex seal going silly on me



so had a few of RSA's finest beer




marked out and redid some porting














redid the exhaust ports




got some new apex seals




all cleaned up and ready for assembly



starting assembly



finished




in the car




made new extractors



Then onto the ida mods

redid the chokes,i.e. tapered machined them



made some more holes !!!



increased the supply holes



all done




in the car



sounding sweet ;D



Happiness !!!!!!!! Ready for the next RR meet

[oldone]

Increased the fuel chamber capacity in the IDA ;D

[qwerty]

Awesome!! Work!! I dunno what you've done.....but I'm sure you do! HAve really been fancying an FC RX-7 recently.....they seem soooo cheap! And I imagine are tuneable???

[Robinxr4i]
