New and standard
 

I've read this forum a lot but i wanted to ask what to do.
My rx7 is standard with 72000 km and 9000 km on the engine, i want to buy a Blitz Nur Spec R exhaust an open air filter and a bov. What else do i have to change, the ecu or just a boostcontroller ?
I don't want to run lean.

judging by your sig id say your running pretty rich and are fine without a ECU for now....

Either/or would work. If you plan on more mods and higher boost in the future, go for the EMS.

EMS ???
More mods like an aftermarket intercooler ?
I want to make it more reliable so it needs better cooling.

And TpCpLaYa that sig of me is from the apex drift rx-7. :D

thanks already

your getting a blitz filter? cause theirs and hks absolutely blow. its unimaginably how much dirt and crap they let go through the filter. go with apexi or k&n. id give u the site to prove this (did tests) but i cant find it.

Ok thanks for the info :bigthumb: , maybe i will buy a carbon airbox.
