Quote from: shaunwil;702566Another answer is the 2nd gen cooler will go into the 1st gen in front of the radiator. Good condition ones are hard to find though !

Thanks, I\'ll just get a generic oil cooler to put in if I don\'t drop on a Mazda one.

Quote from: captainbizzaro;702488I think I\'m right in saying that later 12A blocks had different exhaust ports as a noise reduction measure.

Also-are you certain that all your blocks came out of RX7\'s?

Consensus of opinion seems to be that the inserts differed between engines due to emissions. Why engines for the UK market would have vary from each other though I can\'t work out. Fair enough if UK engines were different from say, US or Aus or JDM engines.
Noise reduction is another reason put forward and probably has some thing to do with it.
The 12a engines are now so old that it\'s very difficult to trace their origin.

Make sure you get one of large enough cooling capacity. The 2nd gen cooler is big.

The original Elford conversion used the s1 and s2 factory oil cooler so as long as I get one that\'s similar to that, I should be ok....I think!

dont worry about the extra exhaust ports i had an elford kit on my s3 and it was fine, dump the etl ignition control guff and get a 12a turbo dizzy, i got mine from Tim at rx motors, it was a lot more reliable, the draw through carb is ace, no lag!

cheers for that...
if i dump the Elford control module, how do I prevent detonation which is the function of the ETL electronics. I read that the module limits the revs and knocks out the trailing plugs if the wastegate fails to limit the boost.
Does the 12A turbo dizzy do that automatically?
I\'m trying to get my head around the wiring side of things...

i struggled to find much tec info on the etl module, the 12a turbo dizzy retards the ignition by 5 degrees of the top of my head and the wiring is non existant as the dizzy is mechanical and vac based. i ran between 6psi (stock) and 14 psi (mega fun) but that required other upgrades. i found some of the etl stuff over complicated and simplified it.

depends if you wanna keep it origional i guess? but im just saying what worked for me.

as for the boost cut im not sure, i just had a discretly mounted boost gauge to moniter it myself, again simpler.

i will try to find some pics and reference stuff.

Cheers Ollie, any pics or info would be a fantastic help. I\'m more concerned about reliability than originality, if that means losing the ETL module, so be it.

give that a go, some info, some pics.

the velocity stack on the carb made a big difference, really responsive.

just watch your oil temps, i had a trubo 2 oil cooler and with a prolonged beating the oil temp would creep up, as the turbo is oil cooled.

i found ducting some high pressure air to the heat shunt made a difference.

FOR OLLIE:-
Just off post for a minute,sure Ian won\'t mind. Would you be able to let me know what happened to your 1st Gen Borque? Was it scrapped? I think I know the Reg and colour of the car you had but I would like to know for definite to make sure it\'s in the right place on my Register. i.e scrapped and not running on somewhere.

You can mail me on dgnock at btopenworld dot com

Thanks Dave.

one of these would be a nice touch if:
a) I could find one
b) swap out the km/h speedo for mp/h

A factory built-in boost gauge out of a 12a Savanna Turbo
I didn\'t know there was such a thing.

Now one of those would be great on your conversion, youve gotta get one. Ive never seen one before is it an aftermarket job or was it original for the jap market?
You only need the rev counter.
