im getting a stainlees steel exhaust with twin dtm pipes on either side. now id like advice on which air filter people recommend for a 1990 na 300zx.

 

Also im interested in buying the na JWT ecu thats up for sale in the for sale forum.

Is the JWT ecu worth $340 and is it any good? and which air filter should i go for.

Ive been told that with exhaust/filter/ecu i could go from 230hp to about 250hp is that true?

 

thx

Those hp estimates sound reasonable. In terms of which filter, you honestly won't be able to tell the difference between them once it's fitted. If I were you I'd go for the cheapest you can find - maybe a second hand one from a TT ?

 

$340 isn't overly cheap but you've got less choice with an NA - it's a difficult to advise on chips for NA as so few of us (if any) have any experience of them.
