hey so i was thinking its time i go non sequential. i have a 99 spec engine, soo i was just wondering if its any different from going non seq on an older spec 13b? i dont have the rats nest so im sure there are some differences.

if so anybody have a write up on going non seq on a 99 spec 13b?

 

You have the black box which all the vacuum lines go into to control the sequential system?

Does your sequential system work? Just curious why you want to switch if it works.

 

yep i have the blackbox! and im currently having boost issues....sometimes it boosts till 20 psi ...other times it stays at 10 but a very very slow 10psi....really bogs down.

i figured i might as well go non seq and simplify stuff to avoid future problems.

 

Do you have any pictures of the black box on the engine? I can't remember which vacuum hoses go to the ACV, pretty sure I can figure it out...just haven't really had time to look at it more closely.

 

hmm ill take a picture soon and post it. im in another city right now!

 

My car have some difference vaccum system than 93-95 us version so I want to switch to Non-Squential with a black box .Can anyone know details?also attach a black box workshop picture.may some guy have JDM older version need this.

 

mattchan, you're tha man! Do you have a bigger scan of those images?
