Hi!

I have a Mazda Rx7 Turbo model 13B year 1991.
I\'ve just assembling another angine and now I\'m sending the car, but now I\'m working on mine.
I need a information:

for best performance is better to close this holes (I didn\'t know their name in english) :





or is better to leave them open?

thanks

Hi Fabrizio, and welcome to MRC sorry don\'t know the answer you are looking for either. But would like to repeat the lemster\'s congrat\'s on winning the best prize in football. What a good match to watch from an impartial stance, well done again.

I am travelling to Italy at the end of this month for a training course on the Italian EV liferafts. Should be good but will only be there a couple of days. You never know though I may spot you in the RX on my travels. Will keep my eye\'s on Rex alert.........best regards Leigh.

It\'s for emissions the air pump blows it into the exhaust sleeve via those holes makes no odds wether you block it or not to performance. no harm in blocking off but does effect emissions if you do.

Hi Fabrizio and welcome to the club i\'ll move this thread to the engine section you should get a better response then. It may also be worth you posting up a few more specs so people can advise you a bit more. ie what turbo is it stock or aftermarket what fuel, exhaust systems are you running and what sort of power are you looking for?
