Gs to Gs-t

[xdsmx]

Hey guys, im new to the dsm world.
I got a 1997 Gs, i wanna convert it to a Gs-t im sure theres a bunch of threads on how to do this, I just couldn't find what i was looking for.

I picked up a big 16g TD05 turbo, and im gunna run it with a 28"x 15" godspeed intercooler.

Also my head gasket blew last week, I was wondering what size the standard gasket is, and how much bigger i need to go to try and run 10-12 psi out of stock engine without upgrading pistons and others etc.

Ive been looking at turbo headers online since mine are rusted out and i want to find one that fits my turbo and engine perfectly.

Amazon.com: 95-99 Mitsubishi Eclipse DSM Turbo Manifold: Automotive

this is the one i was looking at. but i didnt know which way i could go.

basically i just need help to find out how thick of a head gasket to run, and what kind of headers/turbo manifold/downpipe to use. im stuck here, and im not looking to spend a whole lot of money

that turbo looks like a fake ebay so dont expect alot from it, just google how to turbo a 420a and all im sure you will find alot of info, if your talking about dropping in a 4g63 well i would say forget it unless you can weld and do custom fab.

here is a few googled links.

Does that have an adjustable waste gate actuator on it? If so your looking at an ebay special.

Also, are you wanting to Put in a 4g63 engine? Or turbo the 420a? If so your gonna need to fab a lot of stuff, and yourprobably gonna want to drop your CR to 8.5:1 though, I believe with a good tune running the turbo on 9.0:1 will be fine.

 

[xdsmx]

no i wanna keep the 420a engine, and yeah it was all cheap stuff but its only temporary for me anyways.
moneys tight, but i just want a little extra juice out of my car.

and i do believe its adjustable.

is it possible to run like a 2-3mm head gasket to lower the cr down enough to run 12 psi?

Get an MLS headgasket. That manifold is for a 4g63. You need one for a 420a, they are for sale on ebay.

^^ It may not be pretty but thats probably what you'll have to settle for.

You might have to make a custom downpipe(im not sure on that), but as far as i know you do. I dont know for sure as far as handling boost so like the other guys said refer to a how to boost a 420a. Google will find it for you.

Stop what you're doing. Stop buying parts right now before you buy a bunch of stuff you're not going to be able to use.

You do know you have a Chrysler 420a engine, correct? And that the turbo DSM's have Mitsubishi 4g63's? If you want to make your car into a GST, then you need to swap engines, which should run you a couple thousand dollars. If you just want to make a GS that's turbocharged, then you need to read a few threads in the 420a forums on how to do so. A turbo-kit is going to be the easiest way to do this, but if you want to piece together your own kit, then that's your choice.

You're either going to get crappy parts for cheap or nice parts for some cash. Mod your car the correct way with the correct parts one time. Don't do it with cheap parts many times over. The 16g you got is an ebay version, which probably won't last terribly long, even if you get it to mate up to anything else you buy for your car.

Also, keep in mind that just putting a turbo and manifold on your car isn't going to make your engine happy. You'll need additional fuel modifications to compensate for the 12psi you want to run, which is pretty high for that motor without any other modifications. To control that fuel, you'll need gauges, tuning and datalogging materials, etc. etc.

In other words, you can slap a turbo on your car and run 12psi all you want, but you'll spend the next few weeks picking up the shrapnel all over the highway. Read, research, and do things the right way first.

haha i do know my cars the 420a and its the same engine as in the neons and other sorts.

i do understand i got some shitty parts, but i can handle that.

i screwed up when i first got the car, because i was told it was a gs-t.
and obviously i should of known better, i didnt know anything about eclipses at the time.

if i lower the cr with a thick head gasket and run just a little boost i should be fine right?

 

[MrBoxx]

No, I don't think that's going to cut it. I think you'll need to get all the fuel modifications and tuning capability, as well as the intake, exhaust, downpipe, O2 housing, turbo, and manifold all squared away as well. Like I said, there's more to it than just putting the turbo physically on the car. Lowering the compression ratio is a start to running boost, but it's nowhere near the only thing you have to do.

 

[kamikazi]

to do it and run it efficently i would buy a complete kit it will run u anywhere from 1500 to 3000 but honestly bro id sell it and buy a gs-t out right i found mine for 1300 dollars had wheels outta alignment and a sputter under boost i changed the plugs and had it alligned and she runs beautifully just keep looking bro u should find one in time

 

[necrotopsy]

things like this make me sad...

stop modding your car right now. just stop. you obviously DID NO RESEARCH before you started buying crappy stuff. "oh i want to turbo my car, lets buy a turbo! W0O0o0o0o0!"

guess what, your turbo is going to be useless unless you make a custom manifold. whay do you ask? because that turbo has a mitsu style flange, and all the manifolds for the 420a (that i've ever seen) are T3 style.

your engine will handle 8 psi on the stock internals for about 30k miles (more if you don't go into boost often). and that's assuming your engine has perfect compression across all cylinders.

you have a blown head gasket now and you want to started forcing more air into, yeah that sounds smart. you should fix all the problems with your car before you start thinking about how to make it go faster.

as a smart person once said about performance cars:
Cheap - Reliable - Fast

pick two because you can't have all three.
cheap and reliable = it wont be fast
fast and reliable = it wont be cheap
reliable and fast = it wont be cheap.

even if you bought a good turbo t3 style turbo, a good manifold, you'll still need upgraded fuel lines, upgraded fuel pump, fpr, a bov, a boost controller, a way to tune it, bigger injectors, among other things.

to go turbo IT ISN"T CHEAP. so throw your small budget out the window, or don't go turbo.

nuff said.

 

[TSI from Hell]

Do not turbo a car on a budget. PERIOD. If you're on a budget and absolutely want a turbo car find a GS-T or a GSX and do the maintenance and enjoy. I know it's not what you want to hear, but it's how it goes. You'll end up with a hacked up piece a sh!t that nobody will want, not even you and thats all wasted time and effort for fvckall. So please, again, save yourself the headache and learn from more experienced member. Good Luck!

 

[DSMReviver]

bud, sound like its alot of work. the turbo exhaust manifold you got to make, i believe there are non that will work with 16g turbo(for your GS). you might be better off with a t3/t4 set up which you could buy exhaust manifold for your car.

Head gasket can be standard one form factory, but i would advised you to get ARP's head studs to prevent head lift.

Good luck man, keep us up dated.

 

[DSM1G90]

..trade your GS in for a GS-T, or a GSX .. be the cheapest route since the factory got it right the first time ..

 

[TotalEclipse21]

I had a 420a and wanted a little more power. I upgraded from non-turbo neon to turbo neon. =) Honestly, buying a turbo car is a lot cheaper and takes less time than making one. If you don't upgrade internals, electronics, fuel or intake to handle +8 psi then you still won't be as fast as a stock 4g63.

 

[necrotopsy]

^^ that's not true. you will be faster than a stock 4g63 with a stock turbo'd 420a (tuned right). assuming both drivers are of equal experience and skill.

but while you've already dropped 2k into your car, the 4g63 guy hasn't done anything. so you're already way behind.
also to throw that out there the record HP for the 420a last time i seen was 718 WHP. isn't the 4g63 somewhere in the thousand range? maybe even 1200? so yeah the 4g63 is a much better engine if you want high HP for cheaper.

How to: Turbo your 420A on a budget - Team-2G Mitsubishi Forum

Watsup man, I noticed the link that you posted about the "not so pretty but what you need" turbo manifold and checked it out and I was wondering if that's all you would need to put an all put together (not fake) turbo on a GS and would that really work out better and resist more pressure than some "pretty" headers like what that guy was looking at. Just looking for some advice.

 

[xdsmx]

okay thanks for the help guys.

but first of all, i already explained im new to the dsm world.
so id appreciate a little more knowledge than cutting me down, if i knew how to do this i never would of posted this, right?

okay so i cant accomplish my goals right now.
im just gunna fix the head gasket for right now, and even if i cant find a turbo manifold to fit my turbo and engine, i got a a guy who can weld and do custom fab, so thats no big deal.

and yes i know its a shitty turbo, but it was given to me from a friend, and i did buy a 4g63 intercooler but my buddy has the machine to bend my pipes and get it all to fit.

i just wanted to know if i had to go through all the extra bs to turbo it.

and ive been lookin around for gsx's and gst's and all of them ive looked at were mere pieces of sh*t, my car is super clean, not a ding or dent, perfect interior, neons under the car and inside it, and it came with a rediculous system and 20inch chrome rims, and was in my budget.
