Any one miss the twins?
 
So I was wondering of anyone misses having twin turbos? I have a stock FD and I'm torn between going single or not...I like the response of twins but I'd love the boost of a single...so does any miss having twins?

No regrets; single was the single best thing I did ;)

I miss a running car.

Do not miss twins one bit. With a quick-spoolin turbo and ported motor, you can still have a very responsive car that is SO MUCH easier to work on! You can count the number of vacuum lines on one hand and so much less heat in the engine bay.

I'm trying making a similar decision at the moment too....As even if I do go single I'll have to retain all the emissions controls & airpump to pass emissions testing yearly..(Which limits my single options I believe)

A good working set of sequential twins is great fun on the small windy roads where I live. But just not quite enough power on the straits.....Hard decision :)

CCD 08-02-12 06:13 AM

Nope, single is much better!

i love the stock twins but want a little more,,, BNR stage 3s for me..!

MazdaSpeedDan 08-02-12 12:10 PM

Cant really say I miss em, they were fun, I never really got onto it with my FD that had twins before I sold it. But it was really quick.

RX7Zamboni 08-02-12 12:22 PM

I am looking for more boost out of my twins to and am thinking of going with the stage 3 bnrs

Supernaut 08-02-12 12:52 PM

I don't think twins have much more of a lead in terms of boost response anymore to make it worth the extra hassle. I think alot of people will tell you that a quick spooling single will boost as quick as the BNRs would.

Montego 08-02-12 02:42 PM

You mean my 300ish RWHP twins with forever oil leaks, vacuum leaks (sequential), laggy as heck (in nonseq form)? Oppossed to my 400ish RWHP, quick spooling single with no oil leaks, and no vacuum leaks?

yeah I don't miss them at all.

MazdaSpeedDan 08-02-12 03:16 PM

The sound my Borg Warner S336 makes while spooling up is simply amazing and I never got that with the twins.

dabigesii 08-02-12 05:04 PM

Don't miss them one bit, just make sure you get a proper tune. After that, maintenance on a single turbo car is so much easier and so much more room under the hood.

DriftDreamzSS 08-02-12 07:17 PM

Only when im a little nervous with a cop behind me, otherwise not one bit.

Amen, brother!

But to answer the OP...nope, do not miss the twins at all. After going though 3 sets...I'll never go back.

powerhour 08-02-12 09:26 PM

Hmm you guys really make it hard...haha I think I might have to go single, now time to save up a little and plan out what turbo I want haha, I do hate all the vacuum lines and clutter under the hood

I have windy roads where I live but lots of big straights too and lots of hills haha, I don't have emission where I live thank god! So it's all got to go haha

Haha awesome!

HadaVette 08-02-12 10:53 PM

Nope, still have 'em!

Sam Davidson 08-02-12 11:11 PM

Definitely can't wait to go single but i got a ways to go before that happens.

James Paventi 08-03-12 09:35 AM

Assuming that I didn't live in Cali, with its smog inspections, I would think about a single turbo ... but ...

I've owned two FDs now. I street ported and added a lightweight flywheel to the first one. I won't do either on this car. I like my smooth 720RPM idle, not worrying about stalling on a hot day when using A/C and ... it's a turbo car, the mass of the flywheel causes boost to rise faster ... this almost negates the benefit of a lighter flywheel. Wish I would have known all of this before I spent the money.

My point? Drive (or ride in) a single turbo car a bit. I drove a car (lived with it) with the above mods. They just aren't right for me. See what you think of a car that starts boosting at 4Kish. Definitely wouldn't work for me ... not in Los Angeles traffic.

:nod: After 13 years of daily driving all sorts of FDs I like the tiwns for running around town and having fun on the back roads but a single is a no brainer for track use.

ouch! My GT35R hits 10 psi by 3200 and 15psi by 3400-3500. Given that it pushes a heck of a lot more air than the twins, as soon as it starts building boost the car moves. And it's not laggy either when I'm past my boost threshold the full boost comes on real quick.

I took this vid for another member, it's not quality but it gets the point across. Anyway it's from a 3rd gear pull, drop the hammer at 0:02 wastegate opens at 0:03:



James Paventi 08-03-12 12:30 PM

Huh?! (In honor or what used to be below your avatar.) :)

10psi at 3200 is impressive. I hit 10psi at about 3000.

How's the ramp up to 10psi from a stop light? Does is happen all of a sudden from 3000 rpm on? I just looked over a log from this morning's tuning run in to work. If I floor the car in 2nd gear at 1500 rpm, my boost starts at 2100 and peaks at 3100. The ramp up is a fairly linear slope on my PFC chart.

Put another way, if I would like to accelerate briskly (not race) from a light I rev the engine to about 2000 and let the clutch out. The turbos are spinning enough at this point that response is nearly instant.

What's does your intake / exhaust look like? The limit in my setup is the stock cat.
