Is it worth changing from TT to single turbo?
Hey everyone I'm relativity new here and i was wondering IS it actually worth spending oodles of cash changing my Rx7 from twin turbo to single? iv read in other places that the twin turbo setup is not the best and they work better from a single?

I can tell you to go and get a Big turbo,2 thousand dollar ecu and a 6 thousand dollar Paint job with Flames..but do you NEED it,or want it?

If it ain't broke don't fix it. So if your car is running fine don't "upgrade" to single turbo and risk taking your car down. The point of owning your car is to drive it and enjoy it so just do that until your at a point where it's either not enjoyable anymore or not able to be enjoyed lol. Just my opinion.

REVO tune twin turbo or BNR stage 3 Twin turbo upgrade.....
Ok Twin turbo sequential is very complicated becouse of rat nest, but imho is one of the good and bad thing of the FD...
I love the rpm range coverage of the stock (or upgraded stock twins), and it's a thing that NONE single turbo can do...
Imho if your target is 300-340 HP you can stay with upgraded twin turbo sequential and you have a faster car (on the track or mountai course) then single turbo....if you want more then 360-400 HP, hten go single all the way....
If you want a simple (LOT) engine bay and less trouble with hoses..go single...
personally i NEVER change my stock twins (2001 JDM) with a single turbo setup...but near me there are only mountain course then.....
And in 2 month I buy REVO tune complite twin turbo system

The sequential twin system was designed about 25 yrs ago, and run by a 8 bit ECU. It was clever and cutting edge back in the day. Produced instant 6 cylinder-like power low in the rev range and brought a big grin to your face when the secondary came on-line. Technology has advanced in both turbo design and management. Today with a decent standalone ECU, something like the GT35r and supporting mods you can have your cake and eat it too in some respects. The system will be vastly simpler, more efficient, produce less heat but with more power...and with (as I understand it) nearly zero lag...as the sequential twins of yester-year.
BUT it will cost you. In addition to have supporting cooling and fuel (larger pump and injectors) modifications and standalone in place, you'll have some money in the purchase of said system with manifold, wg, exhaust etc. There will be oil lines to run and a host of other small but important modifications. And installation if you're not up to it.
I have no idea how this would effect emissions if you have that to deal with.
To the extent you're able, you can choose to improve on the stock sequential system by adding a standalone, removing emissions, cooling modifications and and simplifying things as much as possible. You won't have dyno numbers to brag about, but it's a fun car and generally reliable. Or spend the bigger bucks and go single.
FWIW I'm still running the stock sequential twins.

So, what's your point? Only Series 6 was ever imported to North America, for three model years 93 to 95. Regardless, it has little to do with the OP's question.
And similarly the later twins were were re-designed for more efficiency and capable of only slightly more power at stock boost levels. They were still journal bearings and suffered from (essentially) the same complicated sequential system and other short-comings as the originals. IMO, there's little reason to retro-fit the S8 turbos, ECU and incidentals into a S6 car with the alternatives out there.

I ran the stock sequential twin turbo setup on my car for 4 years and I have had a GT35R single turbo for almost 3 years now. Both have been reliable and unreliable and I love them both for different reasons.
I would say, ride/drive in someones car that has a single turbo and decide for yourself. Just keep in mind, it's not just as simple as buying a single turbo kit. You have to have the supporting modifications, such as upgrading the clutch, the fuel pump, the fuel injectors/rails, the ignition system, the ECU/tuning, and usually even more.
Fast, cheap, reliable -> You can only pick two.

In the interest of being balanced on the argument....even keeping the sequential twins with a PFC and a State that isn't obsessed with emissions testing, you can remove that equipment on the FD. Doing so will reduce the number of solenoids, vacuum lines and check valves by about half. It also produces some "extra room", especially when the air pump is removed.

my friends do the same crap cuz their parents pay their bills and they can afford crazy mods for their cars. I'm 23 and I pay my own way, so my fantasy mod list is further away than i hoped.
There is a good amount of untapped potential in the stock twin turbo if you tune other engine interals the right way.
