how to get more HPs from a turbo eclipse 95 GST??

[chiquirichapara]

hello

i have a 91 non turbo laser, but i bought a 95 GST eclipse i was sick of the lack of power of the non turbo engine..
i have a lot of quiestions since is my first turbo car.
let me said first the im from guatemala so if my spelling is not to good please sorry.
i want to buy the full catback exhaust system 3" with the down pipe (here in guatemala i dont have problem withemission control), now the car is at this moment stock the only things the car came where a turbo timer and a blow off valve.
i bought on ebay an air intake system (the one near the turbo) but where i can buy the one near the manifold???
i mention this because this mods help me a lot on the non turbo engine.
Know my question is besides this what else can i do to gain more hp.
i saw on ebay a 16g turbo with a turbo manifold, but do i need a bigger intercooler?, do i have do make mods on the interior of the engine? how much psi can i go whit out blowing the engine??


thanks very much for your time!!

Welcome To Extreme PSI
Forced Performance Turbochargers

Forced performance.net you can get a FP manifold for a good price. I think they are $275. Do not buy a cheap 16g turbo. You need to buy a MHI 16g turbo (MHI = Mitsubishi).
You can run a 16g turbo and use the stock intercooler depending on your boost level. If you are are on stock injectors, I wouldn't go more than 14psi.
Here is a breakdown of what some simple mods that will get you more hp:
MHI small, big or evoIII 16g turbo
Downpipe/catback 3"
Turbo manifold. Port the stock one or get a fp manifold. Everything depends on your budget.
Change out the o2 housing. Megan racing or ssautochrome have some on ebay that can be had for cheap
Boost gauge is a MUST
Then after that you can get some 550,650,or 680cc injectors AND an apex safc 1,2 or neo. Then you can up the boost to 20-24psi.

thanks for the info!!!
whats a FP manifold???
the 16g turbo kit with a turbo header cost $600.00 its that cheap for a turbo??
whats an apex safc??
do i need a boost controller on the 16g turbo for 20-24psi?? do i need to do anything on the interior of the motor for the kind of boost??

All your questions and more can be answered with a few minutes of searching.
Anyways an FP manifold is the exhaust manifold that forced performance makes.
Is the turbo kit you are speaking of off ebay? If so there is a good chance that it is a knockoff and not an actual MHI (mitsubishi) 16g. Also most of the tubular manifolds sold on ebay are of cheap quality that crack easily.
You will need a boost controller to raise the boost anything over stock levels.

 

[Gamble97]

Oh you said something by the turbo I thought you mean manifold. Anyway manifold is the header on a turbo car. This is the fp manifold. It's not needed but it gives good gains

This is the safc.
Apexi SAFC Air Flow Converter from AlamoMotorsports
They are inexpensive tuning devices to compensate for your a/f ratio.

I don't know what the stock boost wastegate is on a 16g, I'm assuming 14ish lbs. So to run more you would need a boost controller.
I bought my turbo from Welcome To Extreme PSI They have some really good prices.

These are the megan/ssautochrome o2 housings.

The 3 turbos are at the bottom of this page:

Also if you do decide to get a 16g turbo you will need an install kit to connect the oil line, and intercooler piping etc etc. They are not "cheap" This is one of the kits that has everything you need

So my other suggestion would be a fp t28 turbo.
Forced Performance Turbochargers: DSM FP Big 28 Turbo
It's a badass turbo and a good upgrade for 95-99 eclipses. I don't think you really have to change much at all. You should be able to use the stock oil return, the stock oil feed (which I would replace with a ss oil feed anyway) and you don't need the pipe to connect to the intercooler, it should just line up just like the stock turbo.
Also what makes these better than the 16g is that they don't spike as high in boost as the 16gs. These turbos are good for some high 11second passes.
I would recommend this turbo.


Another thing that everyone and their mothers do on their eclipse/talons is to upgrade the stock fuel pump. The stock pump is terrible. A walbro 190 and a install kit will be good enough.
Forced Performance Turbochargers: Fuel System
Just be careful installing it, make sure you have less than 1/4 tank of gas so you don't spill anything and try to not bend or kink any lines because they can bend easily.

Here is a stainless steel oil feed line for the turbo

That should be enough for now.

Check out www.dejontool.com or ebay for some hard intercooler piping.
eBay Motors: GREDDY INTERCOOLER PIPE PIPING KIT ECLIPSE TALON DSM 2G (item 170235627530 end time Sep-30-08 20:33:08 PDT)

index used to carry some, but I haven't seen any lately. Also you will want a new blow off valve. A stock blow off valve from a 1g eclipse or a greddy type rs can be found for cheap and are better than stock. But like I said it all depends on how much you want to spend.
There are better blow off valves, but these are some cheaper ones that work well.

well ebay 16g's arent really good a real 16g turbo will run anywhere from $535-$600 depending on where you get it. If you are wanting an intake manifold you have have to tune the car or you will run on lack of power by what kind of air and fuel the computer is reading. as for exhaust well to me exhaust is exhaust i think its all the same pipe just different sizes but i would go for megan racing its good exhaust for the buck. If your wanting power there is alot of options for dsm's but its all in your budget too. this is what i would do.

Since you have a 2g these are the mods i would do.

Real evo 3 16g with install kit dont forget it or Big T-28 turbo
AFC or DSMlink or some kind of tuning software depending up on how much power you wanna run.
for fuel 550 or 650 cc injectors will do with a walbro 255LPH fuel pump
Exhaust i would do 3" megan racing unless there other exhaust out there that cheaper and good.
manuel boost controller and boost gauge.
intercooler piping or go with a front mount.
You wouldnt need an intakemanifold unless your going to make alot of power so your stock is for about 300-350 hp.

 

[Gamble97]

FYI, I've had really bad luck with megan downpipes. They never fit right. To get it to fit right you need a evo3 o2 housing.

 

[chiquirichapara]

thanks to all for your replies!!!
since im from guatemala i have to ship from US all the parts you all have recommended, because here its very hard!! maybe i could find somo evo III parts here.
do i need to replace the upper intercooler piping, if i change it for a front mount???
what happens if after changing the stock muffler for a catback exhaust 3" i change the stock injectors to 650cc and the fuel pump, with the stock turbo and turbo header still on the car??

 

[Gamble97]

I have to make this quick. You can not change injectors without having something to adjust for the fuel, like dsmlink or an safc.
EvoIII parts would be good upgrades if you can find them. The turbo manifold (which you call the turbo header) the evoIII o2 housing, the intake manifold, the throttle body and maybe some others.
Depending on the front mount intercooler (fmic) yes you will need to change it. You can get an obx or ssac or something off ebay for cheap that comes with all new pipes.
You can change the exhaust and downpipe and leave the stock turbo on, however it will boost like 20psi (22psi in my case) and the turbo will not live very long unless you take it easy on her or get a boost controller to lower the boost.

All of these performance mods are great, but you still have to remember about all of the maintaince. More power is going to put a greater strain on your engine, so keeping everything in working condition will make you get the most from your upgrades.

which of this turbos is better??
GT-35R or the SBR GT-14???

Whow! Slow down there! The GT35R and the GT14 are awesome...but way more than you'll be needing anytime soon.

To support at 35R you'd need a lot more than bolt on mods, that's where you start upgrading the bottom end, beefing it up to take the immense pressure that turbo shoves in those cylinders.

I'd recommend an Evo III Big 16g. You'll get plenty of power without needing to rebuild the engine yet. Just make sure you have all of the supporting mods

-Walbro 255lph
-A set of Evo III 550cc Injectors are a good cheap option
-A FMIC, I'd recommend SSAutoChrome. They're cheap and work better than a lot of GReddy's
-An SAFC of some sort, or a GM MAFT to compensate for the larger injectors
-A boost gauge of some sort, just make sure you get one that reads in LBS not bar...biggest mistake I made...ugh.
-And it would be really good to get a Wideband o2 sensor of some sort.
-Manual or Electronic Boost Controller, I'd recommend the manual, I had a lot of issues with boost creep on my GReddy Profec B
-A 1g Blow Off Valve (BOV) There's a really cool mod you can do...Dodge Garage Mod I believe? Could be wrong, but that's what's going on my car next.

Can't really think of anything else to support a 16g...anyone else care to add to my list?

always keep in mind the website vfaq.com there is alot of good material on that site

thank for that, i was searching for info and those two turbos pop out, now what do you think on the 20g turbo.
my goal for the car is to be a daily driver and on the weakends take it to the track, so i want the bigger turbo with out rebuilding the engine (just bolt on mods)

 

[JusMX141]

I'm a fan of the 20G. It's a rather durable bolt-on turbo upgrade (doesn't require oil and coolant line modifications like a Garrett), although some folks don't like the price which is why they choose the Evo III 16G over the 20G.

New, the 20G will cost $300-$400 more than the 16G; which leads many guys to buy something a little bigger for less money (i.e., Garrett 50/60 trim T3 Hybrids, Holset HX35, etc.).

 

[Gamble97]

The T28 will suit you perfect I think.

 

[oVaBoost]

t-28 would work very good on your car so will a evo3 16 anything bigger you would have to upgrade alot of things like fuel, some kind of tuning software, ect and it wouldnt be as reliable.
