Just curious, how long have you been running a single turbo setup, how much power are you making, how manytimes and/or how often do you need to rebuild, etc. Just a matter of curiousity.

 

The car is a lot more reliable. My air intake temperatures are a lot lower than with twin turbos, my water temps are a lot lower and more stable as well, and also the car can take a lot more abuse on the track before it gets hot.

I would definitely recommend going single over upgraded twins to someone who is planning on keeping their FD for a long time provided that the car is properly tuned

 

 

 

so in general, a single turbo at 17 psi with pump gas is more reliable than a stock tiwn turbo at 15 psi right? also, how long will the turbo last before it should be rebuilt or replaced?

 

17 psi is pushing the envelope and asking for a motor rebuild. I would never push 17psi unless I was using at least 100 octane. On pump gas the most I would push is 15psi. It's really not a good comparison to compare stock twins at 15 and a single at 17. At the same amount of boost, the single turbo will last longer, put out more power, and also be more reliable and run lower all around temperatures.

 

more reliable than twins becuase of the heat that twins produce, more space in the engine bay, lots more power!!!

 

I love my single turbo setup!

It makes 400rwhp on pump fuel all day every day. I get good fuel economy and its a pisser to drive!

Wouldn't have it any other way

 

I think the comparison you might want to consider is two cars making the same power (360RWHP for instance), but one has a single. Assuming the details are sorted out, the car should be more reliable with a single.

Single single single...

1. Lower temps - very hot topic for rotaries!
2. Simplier and less to break - important!
3. More power!
4. No "boost bump" at 4500 rpm to make that edgy corner damn right scarey!
5. It is cool!

rock solid, easily adjustable with avc-r

7 psi avcr off
10 psi setting a
15 psi setting b

every time! no more boost leak vac hose issues!!!

 

I am pretty much amazed every day I drive my car, with single turbo.

I have 566bhp or around 485rwhp in full street trim (pump gas, road exhaust, air filter etc). (In your language "dyno jet") and average 22mpg city driving.

It is my daily driver and have had it in this set up for over 3 years, Only had to overhaul the Turbo once due to my stupidity (I insulated the exhaust housing and manifold "bad idea !!!").

Aside from this, the engine has been totally reliable.
