Twin turbo? [Merged 11-6]

[dsmclipse97]

So for the third time since i have owned an eclipse (ive owned two), some random person has come up to me and asked if i had "the twin turbo model" eclipse. Of course, i laughed, cried and shook my head all in one motion. But this time it got me thinking. Is it actually possible to make a twin turboed DSM? I know its not practical. I know it would cost a TON. I know it most likely wouldnt fit. But i would still love to hear from you guys, is there any remote possibility of someone doing this to their DSM? And if not, why do people keep asking about the phantom "twin turbo eclipse." What in gods name makes people think they made eclipses with two turbos. Actually, same question applies to the infamous "V-6 DSM" that i am repeatedly asked about. Dont flame i know its a dumb question(s).

People think they are twin turboed because of the power in it. I met people who thought there turbo was a v-6 because no 4 cylinder can have that much power. It has been done and its not efficient at all. Just search for it and you will find pics. I think a shop did a twin turbo 14b and the car made more power with a 16g.

Youd have two cylinders per turbo, thats retarded. No offense.

id do the same thing, laugh so hard that id cry... Then after telling them they are a retard I would slap them. I have heard of this before though. I think people hear something and they think its true. Not practical like the other dude said two cylinders per turbo wouldnt be very fast.

From what I've read, the engine is just too small. I think it said in Corky Bell's Maximum Boost that under 188ci motor its too inefficient to twin turbo.

Having 2 cylinders per turbo wouldnt be the way to do it IMO. You would have a better go at it if u took the Supra method as i will call it. Put both your turbos basically one after the other. You would of course need a built motor, 2.4 preferably because of the torque it would produce. I would take, say a 16g for my first turbo to kick in first and do most of the power. Then like the Supra the 2nd turbo would kick in around 4000RPM's. This way your not acually twin turbo until your motor gets a good ways into its powerband.

Im no car genius but thats like the way to do it. Having 2 cylinders trying to spool up 1 turbo each seems pointless to me. Imagine driving your car with only 3 of the spark plug wires attacted. It feels like a DX Civic could rape ## ass from a roll . So u can only imagine 2.

wow. i didnt think it could actually be done. thanks for the posts

none taken. I also think its quite retarded. What 20psi GST was saying does make sort of sense. Im sure there is some silly ass reason why that cant be done either.

 

[MyBeatGSX]

There really isn't a reason why it can't be done, it's just probably not worth the effort. If you can come up with an easy way to route exhaust through 1 turbo at low RPM and both turbos at high RPM, then by all means go for it. Running them sequential is the only way to get a benefit (as already stated). That's if you get one at all. Like Glliw said, under a certain motor size, 1 turbo is the most efficient way to do it.

Sequential is such a complex setup that it really isn't worth the hastle or money, unless you are just trying to be different. I'm sure it would turn heads if done correctly though.

The supra twin turbo which is a 3.0L is only 183ci. I would say the supra is pretty efficient with two turbos.

 

[20psi_GST]

If u notice all the high HP Supra's are single turbo. Its much more efficient to make more power out of big turbo then it is for 2 smaller ones. You could put 2 big ones but the car just couldnt take it. Hell even the big turbo supras making 1300HP+ need a fricken shot of nitrous to get it goin.

The supra twin turbo which is a 3.0L is only 183ci. I would say the supra is pretty efficient with two turbos.

It is very efficient but look at the two turbos on them (not sure what sizes they are) And put a single turbo of EQUAL size as both of them combined and see what kinda power it makes. I would guess it would make close to 400 to the crank instead of the 320

 

[TrboANTsi]

last year when i first got my DSM i was searching EBAY and someone was selling a TT setup. Im not even joking it was a custom mani with 2 turbos on it i fergot what kind it looked interesting to say the least. but its definetly cramped.

I dont think so. just a single turbo of the same size would not be able to flow anywhere near enough air for a v-6. Not even close. The 1400whp supras are only efficient if your looking for maximum horsepower. Like you said, a shot of nitrous to get them going. anyone thats looking for a high horsepower streetable car and not a drag only monster would stay with the twin turbos. i was simply stating that there are cars with less displacement than 188ci doing very well on twin turbos

Edit: sorry i misread your post. same size as both COMBINED. thought u meant just one of the turbos. thought you were retarded but it looks like im just illiterate

One variable AR turbo.

One variable AR turbo.

ftw!

Let me know when those become available to normal consumers. The new 911 has one (2?) and makes peak boost at like 1,900rpm and still makes a rediculous about of power. Sounds good to me. K03 spool with T4 flow.

I cant wait to see how expensive they are.

 

[nightspeed87]

single big turbos seem to be more efficent, especially if you dont have a V style engine with two exhaust manifolds.

Theres a guy with a red 96 2g driven around who goes to my school who has twin turbo.
I didnt believe him and thought he was an idiot when he mentioned it but when he popped his hood, yup sure was twin turbo. One turbo sitting right in front of the other I guess to help the other. I looked at it as a waste of time and money, and more to break.

He said he liked it so i dont know, seemed ackward, but it definitly can be done. Just not practical, the only reason youd do something like that to your dsm would be just to say you did it. I shouldve asked the guy if I could go for a ride with him to compare his to how mines felt, since he claims hes running 26lbs.

And to answer you second question, the only v6 turbo DSM that I've ever heard of is on a 3000GT if I remember correctly.

Please dont put our cars down by calling a heavy rock 3000GT a DSM. They are not DSM's. Thanks.

 

[v2ner]

It's been provin time and time again that TT is for bigger engines and a better low to mid range power. Single is for the high end.

 

[JayRolla]

Or single all the way. I know a guy with a TT supra and another with a RX-7 TT. Both have been converted to single turbo and they are rocket ships.

 

[v2ner]

Yea, that's why drag racers go single.

Yup. And I think it might be time for another merge.

there is a twin turbo 3g, hell if you do enough searching on the 3g fourms theres a write up I believe it's a v6 model, running two t3/t4, even on the v6 he made less power then a single turbo.
