Fresh member with stupid questions! please help

Obviously a LOUD free flowing exhaust is part of the fun of an FD .......... I think the over run sound I get on my HKS when lifting off warrants owning the car alone.

I fitted a racing downpipe, a straight middle section and a big rear box with a standard ECU and shortly after my car was backfiring like crazy with no power when trying to boot it and I guess running short on fuel ......... nasty ....... at the time I and the guys at Jap Village  ( whom I bought the car off ) couldn\'t figure what was wrong and we fitted a smaller exhaust which didn\'t change it ( strangely enough ) .......... fitted an PFC and job done.

On the subject of oil in the induction system, I used to loose about a ½ litre verey 20 minutes in to the system on track ..... always thought this kept the turbos lubricated :spank  but must be a bit of a fire hazard ........ I now have a catch tank and a further overflow bottle which has sorted it.

As neil said, i wouldnt go for more than filters and cat-back exhaust on a stock ECU. I personally dont like air filters anyway..much prefer the standard airbox and im not a fan of loud exhausts either on a rex... i much prefer the way they sound on the stock exhaust or the mazdaspeed exhaust...have tried both and they sounded far nicer than the apexi hayabusa which my rz used to wear and the blitz nur spec which the white car used to wear....and dont even get me started on the trust what came with the purple car!

You can\'t beat the stock airbox. it draws cold air from outside the bay and the filter stays cleaner for longer. Only problem is, it\'s bloody huge. I used to have twin K&N induction filters on mine but i replaced them with a stock box, much quiter, much cheaper and more efficient

Yes I had the same thing with my little renault 5 turb, The original air box is effectively like a baby ram air!
 
I have never seen a standard Rex box in the flesh however, from photos they do look "Hu ha Mungus ley" massive!!!
 
My Mrs is in the Rex tonight so no photos yet! Unless you would like to see a lovely red 106 1.1? ibut ts not a normal 1.1 its a look Plus (ding dong) LoL. My everyday motor! bless :InLove

Hooray! Another vote for the stock air box!

The main problem I see with aftermarket kits are that they draw HOT air from the engine bay. The stock box draws from the front of the car.

... and another vote for the stock airbox. With an K&N in my case, and a Racing Beat duct to increase the airflow at speed.

Personally I don\'t like noisy induction kits anyway, plus the fact that you get the hot air that\'s potentially been through an FMIC and the radiator into the engine as Martiny says.

...and when you\'re stationery, its going to draw hot air directly from around the turbos and exhaust!
