I Have Purchased 2 mazda rx7 GTXs 90 models
And I noticed first that the ecu would only let me rev to 7.500 rpm in 2nd gear and lower. but in 3rd gear it revved all the eay to 8000 clean.
So ive done some engine work to both and put on stage 2 turbos.
and i was at exactly 378 ps for both . with fresh oil.
however after doing some serious drifting on the autumn ring and some tight races,
I can only get 359 ps with fresh oil out of the one ive abused.
SO after all that redlineing ive lost 29ps
It would cost a fortune to get that in mods.
Treat you engine well and dont overrev for too long folks.
PS i just got lucky and found a used Shuichi Shigeno Version AE86.
doestn start redlineing till over 10.000 rpm
and with only 20.000odd kms its nearly new
however i did pay 3.800.000 yen . A rare Find.
