[stock1g4g63]

And this needed to be brought back because?

because heheartturbo's.

I like the Saleen....But i'd take this over one. It actually holds the current World speed record for a production car.

Koneigsegg CC-R >*

Is that the back of an HKS blow off valve on the Saleen?? Looks like it...

This may sound stupid or not, but i want to twin turbo my eclipse. Ever been done?
Right now im running mods w/ a killer T28.

I WANT TWINS !

I know you all will say just get a bigger turbo and that will be better then twins... I KNOW
but I don't want to.

All I'm asking is what all would I need to put 2 - 14b's or 2 - 12a's on my eclipse.
I just happened to buy 2 - 14b's so i wanna put BOTH of them to use!

- - - ONLY THINGS I CAN THINK OF ARE - - -
a custom turbo manifold, (but how would i execute that?)
Dual out the exhaust or have a Y pipe into one...
2 downpipes...
Run the GM maf w/ trans.
i figured i could run the intercooler 2 into 1 --[||||||]<

Give me some insight before i do something stupid like this....

OR TALK ME OUT OF IT !

 

[sup3rfr3ak]

i guess first question would be do u even have the money to do this, also turbonetics would be a place to get a custom made turbo manifold, the exhaust is no biggie, but im no expert so the rest ill have to leave to the rest on this forum just my 02

 

[sup3rfr3ak]

i actually got to thinking about that i dont even think ull have room to do that, ull have to get likea custom exhaust manifold where the turbo's are maybe like on top and like fabricate ur hood or something ull also need 2 02 housings and i duno thats wierd idea

 

[snowmansdsm09]

i know its a weird idea but damn twin turbo eclipse just sounds good.

but your right about not having any room... i would have to use some little 12a's or something. still probably wouldnt have room.

i think that would be my biggest problem, space.

 

[sup3rfr3ak]

yea , i do wonder what kinda hp and flows u would get witha twin would be something to ask someone at turbonetics, ive heard of alot of people getting custom jobs like that from them

 

[sup3rfr3ak]

it would be neat to see 2 of those on a eclipse

first off youd need a custom manifold that is tubular. 2 exhaust ports into each turbo. one turbo would have to be in the stock location but a little to the pass side. the other turbo will be down farther to make room. that will be a task in itself.

then you will need a fitting off the oil filter housing that will have 2 outlets to send the oil to 2 turbo's.

then you will need to devise a way to make a Y line for the oil returns to go into the pan.

then you will need to make Y's for the water lines and returns.

and thats all theoretical, i dont even know if the pressures in the oil feed can run enough oil for 2 turbos.

then you gotta make piping to go from the turbos into the fmic(they make 2 in and 2 out fmic's) then make a Y after the fmic to go to the intake(short route also since youll be needing a maft setup)

then you can do a true dual exhaust but it will sound like ass, and wont work if you want to use a o2 sensor, since it will only be reading half(at least thats how i think itll work). youd need to make a downpipe that has a Y in it as early in the exhaust as possible, and stick the o2 at that point, dont want it too far downstream or the readings will suck. or you could do a wideband o2.

it would be a good project if you were a great welder and custom fabricator, and just did it for shits and giggles. cause its not gonna be a weekend project. it would be cool bragging rights to have a twin turbo eclipse, but it wont have the same performance as a single turbo thats double the size. im sure you know theres reasons the fastest supras have ditched the tt for a single big one.

i say if you got the time, ability and will, make it happen. take your time and do it right, nothing i like to see more than someone doing his own custom work and proving people wrong every step of the way.

Another guy did this a long time ago and two 14B's were slower than one 16G and spooled like crap. He didn't see full boost until 5000rpm and it made no power.

Basically it's a friggin stupid idea. Unless your a total ricer loser with nothing better to do but get "points" at car shows just leave it alone. If you acctually drive your car it's a really retarded idea.

Just consider two cylinders spooling up a 14B. On a 4 cyl it takes until 2200rpm to spool it with 4 cyl so make two cyl now do the job and it's gonna take like 5000+rpm to see any boost.

Check with Dough at http://www.ddynopower.com
I know that he had a twin turbo kit for the eclipse, not sure if he still has it

 

[snowmansdsm09]

yea your right... it being a 4cyl. would make it lag like crazy.
the money someone would spend doing that, they could put there car in 11's w/ single big turbo.
all the custom fab. and welding.

TWIN TURBO ECLIPSE - BAD IDEA !!

Someone else should try this, cuz I sure as hell am not.

[snowmansdsm09]

Thank You For Talkin Me Out Of That Mess !

 

[babyman0737]

Well what if all 4 cylinders fed both turbos? As in you had one turbo coming off the exhaust manifold, then one off that turbo (just using the spent flow from the previous turbo? You could have a tiny turbo first to spool quickly, then something larger downstream from it that lags a little more and picks up where the tiny one left off? Would that even work?

Learn how cars work, and for the love of DSMs, please, please search.

a couple days ago a local claimed that he used to have a twin turbo 95 gsx, well i had a hard day and instead of just nodding my head like i usually do when i hear things like this, i raised my bs flag, and then today he actually sent me pictures of his old car, i apologized and sucked it up, he was running twin t25's with custom oil setup custom ic, very custom idea, but he later dumped the idea and yielded higher gains with a big 16g, i still give him props

he would have had better luck with a T25/20G sequential...
man that thing had to have lag like a biatch running 2 cyl to a turbo, even a T25...

 

[eclipse13]

looks like it would be a pain to work on. That is awesome that he actually did it though.

 

[igopoopy]

still wasnt worth the money in the end

 

[TierNose]

props for creativity and for actually not being full of bs

 

[fulanititoo8198]

By any chance do you know if ever dyno'ed it or ran it?

 

[Defiant]

You'd need motorcycle turbines to make that worth the time. 1-liter isn't enough puff to drive a T-25 in a driveable fashion. Those spider-leg exhaust tubes are throwing away a good 15%.
