Re installing engine and switching to non sequential

So pretty soon I am going to remove the engine and do a full rebuild and clean up the engine bay etc...
And I was wondering if while I had the engine out is it worth redoing the vacuum lines for a non sequential turbo set up or shall I just put it back to the sequential twin turbo set up. I plan to switch to a single turbo in the near future is that helps. Thanks😃...

if it were me I'd go straight into the single turbo conversion while you've taken the trouble to pull the engine out
There's an article that goes over the installation process here: Triple-R: GT35R Single Turbo Conversion Install
I'm sure there are others. But that's just the decision that makes sense to me personally.

My vote for single too. Get Efr turbo if you can. Efrs are awesome, if not, get bw sxe line. Good luck.

400-450 hp may be "moderate" by today's standards but that's definitely single turbo territory for an FD. I've heard of twins reaching this range, but rarely, and what you don't want is to spend the time and money on this rebuild only to have it overheat. You'll definitely want a standalone ECU, you might've known that already, but it can't hurt to mention. Be sure to research for as much info as you can.

Like mr "Fc" said, 400-450whp with twins? Beter spend that money wisely and go to build section to look what awaits you my friend. Mine is single with all the suporting mods at 13psi i get 330whp dynodynamics dyno with no water incjection.

I'm not wanting to go higher horsepower now I'm going to do that in the future after I save up a bit more I was just wanting to know if it's worth going non sequential due to simplicity with all the vacuum lines now while I have the engine out

Refer to the links Sgtblue sent. I read them myself before this reply and if you don't need to make the big power just yet it does have it's fair share of advantages. The articles in question tell it better than I can.

Sweet I'll do this But can this be done on the stock ecu or Is it worth just getting a stand alone ecu for later on when I go single turbo?

The instructions from Rotary Resurrection detail steps that can be done to run non sequential on the stock ECU, so from what I understand it isn't a necessity. So whether you want to buy it now or later is up to you.
