Hey,
I'm new to the site so lets see if this works out good.  I
have a '95 Eclipse RS and have just started pulling the motor
out to start the build up.  Does anyone know who builds custom
turbo kits?  I do mean custom, I have been considering whether
a twin turbo kit could be made for this car.  The way I've
been planning out how everything will fit, it seems to work, I
just need some help from a shop that knows a lot to see if it
can be done.  I'm located around the Boston area so any
company locally would be best.  I hope to have it be a 500hp
daily driver with the occasional up in boost to about 600hp
for a race weekend.  Let me know what you think, and on
average what do you out there think a custom kit like this
would cost to produce? 
Thanks,
Phil

So, um, why do you think you need twin turbo?

I just think it's a setup you don't see too much with a 4 cylinder, especially an eclipse na.

LOL!! That just made my day!!

HAHAHHAHAAHA That was one of the best replies I have EVAR seen!

Twin Turbo 4 cyl... what the hell would be the point of that???

And how you would even fit 2 turbo's in that engine bay I dont know, I can barely fit one custom manifold and big turby.

I just needed some civilized people just to give me a name of a company, but I guess I'll do it without anyones help on here. I just thought this was the best place to find help considering your all 2gnt owners; but if you don't want to help a fellow 2gnt owner then I would appreciate it if you just kept your wise-ass remarks out of this thread.
Thanks

first off i'm no kid get ur facts straight. and all i really wanted were comments like totaleclipse just gave; he gave a nice respectable answer not like other kid who called me a retard. so if you honestly want respect you gotta earn it first. Thanks total eclipse for the input.

ok her we go and try and keep up
first off go buy Maximum Boost by Corky Bell
read it all then continue reading

first off true twin turbos (2 of the same size) is stupid for a 4 cylinder
(chapter 3: selecting the turbocharger pg 37)

still want to? then your talking sequential turbocharging
one turbo provides power in the low range and then at a predetermined boost stage a bypas opens and begins to spool the larger turbo therefore by the time the smaller turbos blades are about to go supersonic the larger turbo has reached the crossover and can take over the power requirements.

BMW has it on there 535d, Opel has one for a 4 cyl
3rd gen Mazda RX-7 FD's and Mark IV Toyota Supra's use a variation of this and operate in sequential mode with 2 EQUALY sized turbos instead of the more common parallel mode where both turbos spool at the same time.
http://en.wikipedia.org/wiki/Twin-turbo
http://www.lextreme.com/sqtt.html

Cheaper alternative is geting a hold of a Variable Geometry Turbocharger from a 2006 Porsche 911 (997) and making that fit and work

is it possible to do on a 420A? theoretically yes
now for the obstacles

1. manifold design
how do you mount 2 turbos and essentially 3 wastegates?

2. Turbo sizing
you are gonna go Psycho looking at compressor maps and sizing charts id be suprised if your eyes dont start bleeding.
this is the core of the sequential turbo sucess
to big initial and it wount be as efficient as a small single turbo, too small secondary and it will weez out where a larger single will keep going.

3. tuning
stand alone only and able to control between 2 and 3 wastegates for the various stages
$$$$$ for the dyno time required to get these to there full potential

4. Room
this is an ENTIRELY custom job everything is gonna have to be hand fit and fabed up once you figure out how it all works. then you have to figure out how you fit it all in there

just so ya dont think im all bad news, ill leave you with the pics that can get you started if time, money, patience, and the smarts to pull it off

Ahhhh Priceless . . .
eclipse982nrRST "its actually lightish red"
RoninEclipse2G "yeah, they already have a color for that... it's called PINK"

Ok since the majority says to go single, I think thats what i'll do. What turbo/size do you think I should go with to achieve the power that I'm looking for? And how hard are custom manifolds to come by, because the way i want it is the intake side facing the left toward the p/s, and also above the manifold, not below.

Yah listen to Mike he is very knowledgable and he custom makes almost everything on his car himself.

Definately do your research on the turbo first. I would recommend a BB turbo myself. Plus your goal of 500 daily and 600 track would not be achieved by turboing solely. Plus a lot of poeple don't really get much above the 400's with this platform.

Just really, really take your time and research NOW...you will definately thank yourself later.

Yeah, I don't plan on turboing the motor soon, probably more during the winter. Right now I just want to build up the motor so I know it will be able to handle the power that I am looking for. The reason I wanted the intake side facing the p/s was because I have planned to custom fit the greddy 4-row and since the inlet side is on the left it would be the most efficient place to direct it. As for mounting the turbo above or below, i suppose it doesn't really matter to me as long i get the most out of the system. What internals do you all think I should run with the power that I want out of it, since that is the first thing I am going to do.
Thanks again,
Phil

Also with the amount of power you are trying to achieve I would recommend 60mm TB, and a fully P&P intake mani and head. Also a nice 5 angle and some Crower 2's will be in order. You also might want to think about Howell's 2.2 setup.

Good luck!

thanks a lot mike and aggression, those sites are really good and have a ton of info. do you think i should just use a standard bore size or increase it? I really have a lot of research to do...
Thanks again,

hey do you know if that callies 2.2 stroker crank is any good? I also finally pulled my motor and trans out today; I can't wait for the strip tomorrow!

KISS (words to live by)
Keep It Simple Stupid

and like these guys said use the search button

do some reasearch 600 hp daily driven thats A JOKE RIGHT. there is a guy posting about his drag 420a with 30k into it shooting for that range.

you dont like getting flamed. we dont like answering dumb questions.
hmm there is a answer somewhere.

stop asking dumb questions

Im guessing you dont have a staff serving you 24/7.
(hint) you dont have one here either.

We will build you bigger and stronger

Sometimes, i want to beat my head against a wall when people talk about 4 cyl tt engines. Doesn't make sense. Isn't practical. I got asked by this retard who lives two houses down if I had "the twin turbo eclipse because of the hump in the hood". My brother gloats about how he's going to build a crx with twin turbos.....retarded.


About the stroker crank, howell says you'll have to bore 60 thou over to get true 2.2L displacement. Yeah, callies cranks are good. Scat makes crankshafts for our cars i believe and they are far from shit like the name implies.

So you want a balls deep racecar with 500-600hp to the front wheels that you'll drive daily? Why? What sense does it make to even shoot that high for a daily driver. A front wheel drive daily driver that when finished, will cost more than a turbo supra or FD Rx7 in near-mint condition. I guess what i'm trying to say is start small and keep your goals progressive. Stick to one easily obtainable goal and work from there.

Think realistically or you'll be sorely dissapointed. While you're gutting out this eclipse of yours, do you have something else to drive? Will this project have proper funding to meet your REAL goals before you lose interest? Start asking yourself questions and use google to find the answers you cant.

Goodnight sweetheart...yes its time to go...bum bum bum bum bum...good night sweetheart yes I am one little a$$hole......bum bum bum bum....

as you can see from before the twin turbo idea has been done with; and like i just state it was just an idea. I am currently driving an RX300 for a D.D. and make roughly $1400 a month to help me in my build. and if I'm not mistaken i believe Howell says that you only need to bore 40 over in order to achieve the 2.2L, the stripping has already begun, everything is pretty much out of the car. I was currently at the junkyard and found an eclipse with rear discs so I'll probably be doing that conversion within the next couple of days. Motor is completely stripped, I'm just having a little trouble removing the oil pump gear to get the crank out, but hopefully I'll have it out by this weekend. And I will be ordering the crank from Howell alone within the next week, and hopefully the rods, bearings and pistons, by the mid of September from either SlowBoyRacing or ExileRacing. Well that's pretty much it for now.

Goodnight sweetheart...yes its time to go...bum bum bum bum bum...good night sweetheart yes I am one little a$$hole......bum bum bum bum....

It would be pretty cool to see someone twin charge a 2gnt, pull off something like the old crazy group B rally cars with turbos feeding superchargers, 500+ horses out of a 1.8 litre Audi. of course it's financially stupid and totally useless, but it'd be fun.

realistically 300 horsepower is about all that's useable on the street in a FWD car unless you make the rear suspension so stiff that it feels like someone is kidney punching you VERY hard. otherwise you just burn off tires. there are limits to what a car can make use of and still maintain any kind of civility. I've been in some 250-300 horse FWD cars, VERY FUN! I've been in 400+ horse FWD cars, you had to play with the throttle and clutch soooo much to keep the tires from spinning it was highly aggrivating, not fun at all. 300 horses is plenty to catch any corvette asshat way off guard and put a huge smile on your face
