Yes the thread is "Nissan Heritage Collection - Sunny TS Cup specs" which also means 30 year old tech that makes many wonder not just myself but as Feral did also in a conversation, what could have been if the A series was continuously developed without restrictions. Its no dream just adoration.

As for my threads, I dont mind peeps posting something to help with the elusive workings of Mazda headed A series but I didnt want a newb asking can you use the ca18de rods, or can you sleeve an A series, or just use the whole Mazda engine as you have put on the other thread on the Mazda headed A series. You just cant accept that some people think differently and are driven by different goals.

Also I am not comparing carbed to efi "alone" that is your tunnel vision interpretation once again. Yet by now Im not surprised you cant accept that an A series with todays tech cannot make more hp compared to what was done 30 years ago. I had this conversation with Feral on the same subject of the Sunny TS Cup cars, nothing off subject just adoration again for the Marque and general interest. He believed it was possible.

On the carb vs efi you just stated, a carb no matter the size cannot match the fuel delivery/accuracy of todays efi which makes more torque under the curve definitely way more important than max hp.

The dubious figure you labelled A12grunt for the 170hp at 8000rpm he posted, Do you know if its a later incarnation eg. an improved later build where they found some extra power with improved flow, pistons and or combustion chamber design or even a sprint build/tune for shorter tracks just for getting pole position? or is it a misprint or error? Did they use the same dyno? different fuel for that year/race/series/sponsor leaving more room for higher compression? why not just say its a confusing figure just in case or do you have concrete information to disprove it?
