87 UK N/A 2nd gen differences?

[ninjasx]

My 87 N/A`s inlet manifold doesn`t look like any of the ones in the downloadable manuals or the haynes manual, does it have a 6 ports? if so where is the actuator?
is there an manual for the Uk cars as there seem to be quite a few differences:confused:
thanks

the EU-Version of 1987 N/A look like on the pic below. (soory for a bad quality)

Thanks and REgards

i have a north american spec car and it looks nothing like that .i dont have a distributer just 4 coils if you guys want that set up i can send you what you need including ecu.

[bill shurvinton]

Yup confused me until recently. The US went to full coil per plug setup whilst the UK stayed with a Dizzy.

We also escaped from cats for longer.

DO YOU HAVE THE 6 PORT ENGINES IN YOUR SECOND GENS BACK HOME  BECAUSE THAT ENGINE REALLY LOOKS DIFFRENT

[bill shurvinton]

Yup.

Actually not quite... As the emissions were not as strict on Euro cars the aux ports were butterflies in the manifold not sleeves and were actuated by inlet vac not exhaust back pressure.

HEY BILL DID THEY HAVE 4 PORT NA ENGINES IN THERE SECOND GENS IF SO COULD YOU FIND ME ONE.

[bill shurvinton]

If you mean 4 port 13B these were only available in turbo form.

I have a 9.4:1 13B 4-port in the westfield but this was imported from the USA. These are very rare in the UK.

Turbo 2 blocks with 9.4 or 9.7 rotors in make very good NA power plants though. Should be plentiful with you.

[ninjasx]

so is there any need for the air pump at all? no cats so no emissions test,not needed to open 5th and 6th ports?? can i ditch it without problems?

[wirepounder]

I STRIPED EVERY THING OF MY ENGINE TO DO WITH EMISIONS AND I MEAN EVERYTHING I EVEN PUT A T2 FUEL PUMP IN THEY SAY YOU LOSE TORQUE WHEN REMOVING 5TH AND 6 TH PORTS BUT I COULD NOT NOTICE IT I FOUND THAT THE CAR DIDNT LIKEIT WHEN IT  WAS NOT WARMED UP BUT I THINK THATS DUE TO A BIGGER FUEL PUMP.SOME MORE SIDE EFFECTS ARE BIG FLAMES WHEN SHIFTING AT HIGH RPM;S

I don\'t know exaclty, but I think the AUS N/A was a 4 port version.

In australia they do have many more of the NA 4-ports but these were not from RX7s. They had the US style 6-ports as I recently sold a UK LIM to someone.
