I have non-seq stock twins and I will pretty much buy a T78 within the next few weeks. Most people stick with the twins for "fun" on the street. This "fun" is quick spool time and more power down low.
My question is this....If I already have non-seq, the turbos hit together around the 3800 range, that's acting like a single anyway? Isn't it?? I would just benefit from the T78 since I was told I could have full boost by around 4100rpm.
This "fun" on the street is lost once the car was changed over to non-seq. If I am gonna feel boost, I might as well have the boost hit hard! I know they can bring in full boost only a few hundred rpm higher that stock, and in a rotary that's no time at all.
This isn't another stock twins versus single thread, I would just like to know whether I would ever look back after going T78 and think "What a waste of time and money"!
Any input or experience would be greatly appreciated.

 

There are few single turbo owners who WANT to go back to stock turbos. Most single turbo owners elect to go BIGGER single turbo vs. returning to stock. There are however a few die hard stock turbo guys out there.

Just depends on what you want out of the car. You can't have it all...

 

IT's also a question of how much power you want, and what your level of "full boost" is since that's all relative. When you reach your full boost setting is all dependant on what your setting is and your porting.

 

thats exactly true. this is why non seq is totally retarded. it ruins the car. you are waiting as long as a big single for boost and when you get it its ***** power.
you'll love the single. its hard to describe it. even at 0-3 psi the car moves quickly with a single that size.

remember dont underestimate the cost of the single turbo setup. it is very expensive to do it right

 

so whats the closest single turbo that compares to the stock twins.meaning what single will spool up the fastest? Ive heard something about a gt 35/40 but not much else.dont get me wrong I love the twins.but once something goes wrong with the sequential control system its hell trying to figure out what went wrong.
I figured maybe having a good mid sized turbo would perform much better.

 

rx-6 is the closest. I have the 35r(35/40) and it spools incredibly quick with my street port. I had 15 psi by 3500 or 3600 rpm. Fun as hell to drive on the street, but still enough power for more spirited driving.

Riiight.

Tell that to Kevin Wyum. When's the last time you ran a 10-second quarter mile, even with a single turbo?

 

Ya but honestly, for quarter mile purposes you're leaving the line over 6000 anyway, so whether or not it is non-s or seq should not matter? No?
The motor is street ported by KD and when I bought this car, I bought it for the handling and looks. BUT, once I felt boost(and mind you this only makes 340rwhp, so it's nothing crazy), I got addicted. I thought..."This is incredible, it revs like a 2 stroke!".
And now, honestly, I want to beat every car I can. I want this thing to be the fastest I can get it to go, still having fun on the street. That's why I was told the T78 by everyone. I want to run high 10's and still be able to corner and cruise.
And that's why I thought...well the non-seq setup is like being single, with the small boost of stock flowing turbos anyway, so why not make the jump?
To me....nothing feels as good as huge power. No cornering, braking, drifting, feels as good as incredible pulling. But that's just me.

 

you could always consider the gt40r as well if it's in your price range since it should be able to create the same amount of power as a t-78 with a bit quicker spool.

 

jim I will never run 10s because I dont have a racung suspension and I dont care about the 1/4 mile that much
I may go once after my car is done to see but if I get wheel hop at all I'll just leave. It's not worth it to ruin my nice car

your comment about kevins car means nothing because his twins wont last long at that high boost and getting into 10s requires amazing launches which would never happen on the street. For around town I didn't like non seq much it was too smooth and very very late spool I had to always downshift to even pass a car in traffic

 

That was in response to the comment on "***** power". ***** power doesn't get you into the 10s @ 12x mph.

If a non-sequential car is set up properly, full boost (14-15 psi) should come between 3,000-3,200 rpm. The people who have done the "poor man's" non-sequential conversion (often without removing the catalytic converters) have given the conversion a black eye with their "reviews" of poor boost response. With the gates removed and exhaust manifolds ported, boost rises VERY quickly on a non-sequential car, and mid-range power is significantly increased over a sequential car.

Past the transition point, however, a non-sequential car and sequential car with identical mods should be relatively even in power.
