can somebody please direct me to a writeup of everything involved in converting to non-seq twins? my turbo control actuator has been stubborn for some time now and my turbos are leaking oil faster everyday, and i want to find out a little more about the "dark side" before fully investing in a regular sequential rebuild/replacement. thanks in advance.

 

oh boy... GOING FOR THE WIN!!!

thats all i have to say. please help me still.

 

There's a guy on the forum named Brian Goble that has a lot of info about the switchover - not sure what the website is though - not hard to find. Also, I think Max Cooper has something on that too. Good luck.

here is another

1. Wired turbo control door open and removed actuator rod from door mechanism.
2. Removed lines/plugged lines to charge control.
3. Removed charge relief and capped hole and vacuum line (I have since put it back on, but didn’t hook it back to the vacuum line.
4. Wastegate: Left the direct pressure line (with restrictor) in place.
Removed/capped the line that went to the solenoid.
5. Pre-control: History.
6. Installed down-pipe.

just use the search function on the top of the page.....i know this qestion has been asked about a million times. i am sure you will find all the ifo you need after doing search.

 

thanks for the responses. i have checked out the sites, and the project doesnt seem as involved as i thought it might be. is there anything else to look out for that rob or scuderiaciriani's writeups dont cover?

and for all of you guys running non-sequential right now, how do you like/dislike it in comparison to stock seqential twins? do you notice significantly more lag or any other downsides (ie rougher idle, etc.)? and if you had the choice to go back to stock seq twins, would you?

i really appreciate all of your excellent feedback.

 

Um . . . the project WILL BE every bit as involved as it sounds. There is plenty to do . . . it just depends on how much time you have and how good you are will tools. I am pretty good with the wrench and it still took some time to complete . . not to mention I had to deal with unexpected studs breaking. (ok no jokes about my "brock stud"!) I like it to some degree . . . it is very smooth and you have power for what feels like forever, but you need to downshift a little more to pick up power immediately. No more easy 5th gear passes at 2500 rpm. Now once you get up to around 3000 to 3500 rpms you regain that easy 5th gear pass. Oh yeah, I don't have a new IC yet, but I highly recommend having this mod if you are thinking about non-sequetial because it will really help spool-up and lag.

 

no more seq heads out there? i know you are out there. please share your feelings about the conversion. or would you rather have kept your sequential setup?
