8psi-laughed upon

[eldiabloz13]

if i wanted a beater i would have got one. Real driving? im not guna be rallying or anything i just want a turbo car that is respectibol. If i wanted power i would have got a 5.0 mustang if i wanted handeling i would have got a volvo. I have 4 wheel disk brakes already on there so im good.Now its a fwd so i dont have to worry about handeling to much......i just want a turbo car that isnt a joke and does what it needs to. C'mon how much problems can a turbo gs be.......list them if there really is so many

 

[DSMcrazy3]

Huh, 16 with a highly stressed motor that wasn't designed to be turbocharged. I see many mechanical failures in your future

Funny, I know a 15 yr. old that can run circles around me, and pretty much EVERYONE i know..But most can't so your point still stands..

[eldiabloz13]

exactly......see eveyone thinks its a big joke when a 16 year old comes im and wants his gs to hold 15 psi......im not going to be running that but maybe 13. Im just saying i think custom pistons and rods will hold 15psi.Also i still need to know if i can take gst or gsx pistons and rods and put them in the block........but are they bigger then the cylinder or smaller.....in other words will they need to be bored before they will fit. thanks guys!!!

 

[hystericfox]

like.......?valves and springs right?

All that is going to do is let the motor rev higher without floating the valves. If they think 8 pounds is pathetic, they should have seen my buddy's civic hatch that put down 320hp at 6 pounds. He was running race gas and his timing curve was ridiculous, though. The pressure that the turbo puts out isn't as important as the airflow. If you use a turbo that flows as much air (in CFM) at 8 pounds as a smaller turbo that flows the same amount at 20 pounds, its going to be nicer to the turbo and motor, and put out close to the same power. If they're laughing at you because they think your boost is too low, just show them compressor maps and flowrates, compare efficiency and watch them shrink away because daddy can't buy them knowledge. As for the internals, it would probably be a good idea to rebuild the bottom end to handle the extra cylinder pressure from the turbo anyway. Less chance for disaster.

No pistons and rods from a turbo 4G63 will not work in your 420A, Check out Howell automotive for rods and pistons for your non turbo. Or you can get them direct from hahnracecraft as well. And stick with 8.8:1 pistons, you don't want to run any higher compression then that with a turbo.

 

[DsmKid98GST]

I really think you should re-read what i posted. Its alot easier said than done bud. Id say milk this car and save your money. Otherwise make that bottom end strong as hell and drop 2-3g in it for a turbo kit / custom kit. Research Research and more Research will give you all the information you need. Good luck and keep posting those questions you have and keep us updated.

 

[ddavisaf]

Just remember that you can build your bottom end to bullet proof. But your head will just blow up instead. It's a good idea to worry about the block and cylinder head, not just one or the other.

 

[eldiabloz13]

right guys.....im just going to turbo what i have. I just want turbo rods and pistons because i have 115k on mine right now and i think putten 8psi on them will screw them up and i dont want that. So im going to be getting new rods and pistons anyways why not have them turbo.Now I always thought the compression ratio defined if there turbo or not. But its really what there made out of right?I just figured since i get turbo rods and pistons i could run higher boost like 13's and shiz.That and the fact that people think 8 psi is nothen and needed to know what result it really could give.thanks to all for the help. keep it coming if you wish

 

[hystericfox]

If you drop the compression you can run higher boost, yes. And what are these "turbo rods and pistons" you speak of? The compression has nothing to do with whether they're "turbo" pistons. Some people run high-compression and still use forced induction, while most prefer to have lower compression and run more boost. The thing to watch is how how they're made. Forged internals are stronger, but more expensive than cast.

 

[eldiabloz13]

hahn racecraft.....and what kind of pistons do i need to run 13 psi then.

 

[tylerk]

If your goal is only to get your boost gauge to X PSI, then you have the wrong goal.

If you just want a number to impress stupid people, why not just finagle your boost gauge to give the reading you want instead of an accurate reading?

In fact, you can probably skip the turbo altogether then and just install the gauge. You don't even need to hook it up to anything. Just move the needle to 15 PSI and leave it there.

Alright so you still seem a little confused, so let me help you out a little, pistons and rods fom a turbo Talon or Eclipse will not work in your car. And there is no turbo rods and pistons or non turbo rods and pistons, they're all the same, its just the strength of them and what particular motor they are made for.
First I want you to go to this page and read the entire page top to bottom
http://hahnracecraft.com/auto/eclipse/eclipse.htm
HAHN makes just about the best turbo kits for your car, now I want you to realize you won't be running the exact 1/4 mile times they ran in their car (they have alot of experience driving and it'll take some practice before you become the expert they are).
Now I want you to read this page
http://hahnracecraft.com/auto/tech/dev.htm
Now you know more about turboing your car now I'll show you what you need for your engine, read this page
http://hahnracecraft.com/auto/engine/components.htm
These are about the most important pages for what you want to learn, make sure to read almost every page on their site that related to The Talon/eclipse, read the stuff on fuel, ignitions, clutches, And even the exhausts. It'll really familiarize you with turboing your car and what all it will include, then decide what you really want and need, Then if you feel comfortable and have the money go ahead and call them and see about ordering a Stage II kit, along with whatever else you might need or want, and what different things you might want them to change in the kit, maybe you want the match their stage III which isn't offered for sale yet, but they'll sell you all the components seperately,
Then go ahead and install it once you get it and be amazed at the power increase. Its a respectable way to go, but its more expensive then just buying an already turboed eclipse or talon, its more work (maybe), and you still won't be the fastest, but you'll beat the guy in the stock wrx or even modified honda. Sorry this was so long but I hope it helped ya out a bit, I had a non turbo Talon and was planning the same thing as you. So I know what you're trying to do and hope you go ahead and do it. Instead of caving like me and buying a turbo Talon.

 

[eldiabloz13]

how come it dosent give me prices.Ihave to call and give them the part number? and as for the guage thing its a good idea but they will want to see it in action/look at the set up and see no turbo would be embarassing but i like it.

 

[tylerk]

and as for the guage thing its a good idea but they will want to see it in action/look at the set up and see no turbo would be embarassing but i like it.

Just point at the alternator and say "there's the turbo, it's a JDM Mitsubishi 80G," they won't know the difference.

 

[eldiabloz13]

AHHHHH hahaha ill try that out.

Read around a little bit. All their prices are just in one place:

It seems like you're a little confused on the physics going on in the engine. Stronger pistons & rods aren't going to do a thing to prevent knock & detonation from increasing boost on a high compression engine without seriously increasing octane. You'll need to drop the compression with the JE 8.8:1 pistons from Hahn to allow higher boost as well as upgrade your fuel system to handle the increased airflow or you'll be running lean with high EGTs when you turn up the boost. Needless to say you're going to have to spend a big chunk of cash anyway, so just get the Hahn stage 3 kit (stage 2 + pistons, rods, injectors, PowerFuel module). That'll cost you around $3-4k uninstalled.

 

[eldiabloz13]

I know the dimension of turboing a car. I know that it takes more then pistons and rods. Thanks anyways for the help though. I just need new pistons and rods mine as well get ones that can handle turbo. Then squeez a little more psi out of the deal.

 

[sciroccosven]

Well for starters, you are asking how much boost I can run and what kind of compression do I need to run. Boost is only relative to your turbo. What compression do you need??? There is no way of knowing. You could run 13lbs of boost stock if you used a turbo from an old jetta eco diesel engine and if you had (providing you can find a way to even spool it) a garrett gt60 5 lbs would be meltdisneyworld for you. Say you went with a 14g turbo and had moderate boost. Then what?? How do you fuel it?? How do you control the fuel??? How do you aplly the new power that you have?? What happens when you have too much traction and you start breaking axles??? what happens when your clutch gives out because its designed for a 140hp motor?? You will need an intercooler, your going to need a boost gauge, your going to need a turbo, your going to need a manifold, you going to need a large fuel pump, larger injectors, you going to need a new clutch eventually, your going to want to get wider, stickier tires, your going to need to upgrade your suspension to deal with the weight of all the new parts you have installed, your suspension wont handle well with stickier tires stock, your going to need to upgrade your breaking system with all the speed you have added to your car, not to mention the grip and handling potential. I think you can see where this will lead. I would definitely stop and think before i spend a measly $800.00 bucks. Not trying to be mean but there is alot you have not taking into consideration. well there are my two pennies, spend them however you would like.

let me make it easy for you........when someone open a thread its good to check there car profiles first. You will get a good idea of what there dealing with and why there questions may seem weird sometimes. Now for everyone this is what i have, a smic,t-25 turbo,190 walbro fuel pump,manifold and ic pipes are yet to be made, injectors are 450cc, ECU i need to buy,down pipe....well....ill probly custom make that.How big is a stock exhaust for a gs and how big is a stock exhaust for a gst/gsx(pipe wise).Im getten a safc but i mine as well get e-manage b/c its 40 more and its way better. So there you go guys.

 

[totaleclipse_05]

you are going to need a lot more than that to make your car run reliably. thats only the basics. you need to research more on this topic if this is the route you are taking.

EDIT: 8psi is not laughable for an eclipse nt. that will give it over 250 hp most likely if you are using a fmic.

 

[eldiabloz13]

yeh i know its the basics but im goen basic untill its all in then im going to go back over it and fix what other problems come up......ps check you pms you'll have one from me. what about for a stock 2g smic. How much HP?

 

[out there]

there's a local dude with a stock (cam, intake mani, internals, etc), SOHC, turbo civic...
262whp/214trq on 10 psi and has run a best 1/4 of 11.92@113
it's all about airflow and skill, not boost pressure.

 

[speedy13]

Gs going fast worked his ass off so you wouldn't have to start this thread .use it

http://dsmtuners.com/forums/showthread.php?t=181134

It can be done.you can buy already made manifold and downpipe from ebay.good luck and please,build this car for yourself,not what other people will say or think about you.FTW.

Well... I don't know how they could think you're a joke?...

......420a's have better compression blocks then a gst or x
But don't forget about the rest of the necessary supporting mods.
like.......?valves and springs right?
ETC.!

Oh and I guess all of the almighty “Gearheads” in your area would eat this car alive , I mean since it runs 8PSI and all, http://www.suprastore.com/sinturconkit.html

I waited almost a year before I even posted here because I studied the forums, everyday, answering the questions that had been answered before. I mean just do your research, If you would study all of the differences then you would know the differences between the two engines and that it’s not just as simple as bolting on a turbo like so many people think it is. Next time don’t come in with the same attitude as all the people in your town, when you ask a question do it knowledgably, not like you know all there is to know.
And no this doesn’t mean I know everything there is to know either.
Now do your homework [DSM studying that is] before you get any dessert [turbo]!
