I have read quite about it, right now I have intake, full 3" exhaust with muffled midpipe, FMIC, and Power FC. My primary turbo is only getting about .60 bar boost by 4500rpm, so I figure by going non sequential, I can't get too much worse response, at 5500rpm the car hits .8bar and pulls strong all the way (my WG duty cycles have been played around with a lot and are maxed out right now without getting boost creep). I have heard if its working fine, don't do it, but I am putting down a good amount of power now and the sudden power at 4500rpm already scares me a bit, and it could get nasty when I auto-x the car (spent my 4 years racing with a spec miata...). How hard is it to do and how easy is it to mess up going non sequential? Also is the wastegate on the stock twins external or internal? If it is external how hard would it be to vent them to the atmosphere, I am probably gonna to port it soon. Also now that I have a midpipe, I dont have to do emissions, what stuff can I remove from the engine bay?

 

When I did non-sequentials I went from having fuul boost at 2500rpms to 5000rpms. I then did some porting and got it down to 4500rpms. Something to think about if you want to do it. Good for drag racing, I think you'll get too much lag for autox

 

the non seq is really easy there are only about 7 lines total and 3 of them were already there because of seq.
If you want to do it the full way its still pretty easy.

wg is internal and to port it you have to remove the turbos

you can remove the rats nest, airpump, egr, acv all the emissions crap and get greddy pulleys

lots of questions man!
