lmao....
93redA,
A BOV is not going to increase any performance. The intake will increase performance. However, if you haven't installed a downpipe yet, that is the best bang for the buck performance increase (as well as reliability) modification to start with....

Why do people give advice on things they have no idea about??
The intake will not provide any significant improvements on your quarter mile time. Don't take my word for it, put it on and run till the car pukes, you'll see what I'm talking about. Better exhaust system will provide marginal improvement. Depending on your goal, lowering your drag time requires major increase in power and it's going to be costly.

intake does provide significant improvements....however you really need downpipe/catback to really get the full effect. intake/downpipe would be your best bet, rather than a BOV

RX7s have a speed density FI system (no flow measurement), so you can dump all the air you want without screwing up the mixture.
DSMs have a MAF sensor that measures flow, and will run rich if you dump some metered air.

If you run an open BOV instead of routing it back into the intake, it will richen the fuel between shifts. Now if you vent the BOV back to the factory location it will cause no effect, good or bad. But people that want that Psshst sound will actually run rich between shifts. That is what I remeber from my GSX days...since the MAP sensor does not recognize the BOV being open atmosphere it releases more fuel to compensate. So I feel he could be right...unless RX7's are not like DSM's and how they use the MAP sensors.

Thanks for pointing that out though.

save about 2k and get level 10 to "beef" up your auto and put a hurst shifter on it and you should be faster then a 5-speed... or atleast pretty close...
