Ok guys I need to advice Say I have a 1997 eclipse GST and I want to make it faster then most cars on the road in my surrounding towns but don't want it to be balls fast like 600 HP. What kinds of parts would you suggest getting. To explain myself further I just want a car that can run pretty fast quarters. And I need a turbo that is really quick with less lag that I can run anywher from 10-15 PSI. I know this sounds a little retarded LOL. But I want a car that if like anyone wanted to race me id probably beat if that makes any sense. and im not sure what parts are compabable with what. And im wanting to find a blow off valve that sounds badass. Im trying to reach about 300-350 HP. I pretty much want a race that is faster in acceleration then in top speed. And I need to know what I need to upgrade for my car to be able to handle 300-350 HP. If anyone can help that would be great :D :dsm:
 
Stock 1G turbo can handle from 10-15 PSI. Get a o2 with a dump on it to make the turbo spool a little quicker. Go with a 2 1/2" or 3" turbo back exhaust, medium size FMIC. Do a little weight reduction. Just to get started.
 
Stock 14b can hold upwards of 22psi so...that right there is about for 300+ on a fwd, and fmic are over rated. Maybe at 22psi you would need a little something bigger. I run 15psi everyday on my evo316g on the stock side mount without any problems.
 
I think you need to start using the search function. Read all FAQs, Frequently Asked Questions, and the 2g upgrade path in the tech section. That should answer all of the predictable questions you will ask.

If im not running like a 600 Hp car I don't need to get upgraded pistons and push rods cams and all that do I? or would it be smart to get new ones with engiene rebuild?
 
disregarding turbo longevity, just unhook the wastegate deal from your vac line and let it run full spool if you want to get the most out of that guy. There are guys making really good times with stock turbos if you know whats going on (or get lucky). Get a fmic as stated above, get a logger and watch your knock retard and go from there. Boost controller is also a good idea depending on what you want (as well as for the future keep in mind).

Thanks for the help.
 
i would say get a better clutch, just so you know there are no push rods on a 4g63, it cool your learning and thats what counts. i would get a bigger fuel pump say 190lph, b=mbc, med fmic, hard intake pipe, better air filter, 2 1/2" exhaust and a 14b turbo. with those you should be rolling out pretty strong:thumb:
 
I say do all maintenance first, all belts, plugs, wires, oil change etc. I would also go with a 16g as 14b's are 14+ years old now. Get some evo 560cc injectors, evo fuel pump and an AFC and logger or dsmlink. This way you have room to grow also if you ever wanted more power. Is that whp or crank hp you're talking about by the way?
 
The 16G will take longer to spool than then 14B. Plus for what he wants the stock turbo will be more than enough. As stated above though do the maintenance and get a new clutch. As for the FMIC, that is up to you, I like the PR FMIC.

22psi is NOT close to the heat of 15 psi. Way more heat. I noticed a sharp difference at 15 psi going from the weenie, tiny, poorly overrated stock sidemount with its poor location and size to a 24 by 9 by 2.5 inch fmic. Try it. You'll see the same. Not only does the stock sidemount cool poorly after stock flow levels, it becomes a choking point quickly at anything close to his horsepower goal as well.

The stock turbo does NOT! allow him to reach his goal of 300-350whp. The 14b with an upgraded turbine housing is possible. More than some have done this with a STOCK 14b from a 1g car. A small 16g is probably best. The ideal turbo would be the 14b with the 7 cm^2 16g turbine housing. Smallest turbo that will support 325ish hp. So the fastest spool possible is there.

550s-650s
SAFC
Intercooler or water injection
14b to small 16g
stock piping
stock maf
walbro 190 or 255 fuel pump
Thats about it

If done well, this setup is VERY "sleeper".

No one in their right mind turns the boost up without a boost gauge. Since the stock gauge doesn't read boost. It reads an guess as to what the boost is from the ecu. And no one attempts to run these mods with out logging their results to see if there even close to a tune that is worthy of the potential of these mods.

Do you plan on racing one of these? Or are you planning on buying one? You have an n/t car in your profile.

Don't race on the street. Get a slip and dare some one to match it when they get the nerve to call you out. Tell them "you'll give them every benenfit to run there best. So show a slip that's btter than this." Please don't kill or mame people for the sake of vanity. A 'real man' gives anyone the opportunity to bring there best. At the strip that can be done.

This is probly the route I am taking with my car.
 
How much of a difference would the SUPER BIG Side mount Intercooler from Dejon make compared to the stock SMIC?
 
I dont plan on getting a fmic. I will run meth injection to get my results.
 
So, you have a 97 N/T and a 97 GST?
Just to make sure, I'm confident that you know that they have different engines and a mitsu turbo will not bolt onto a 420a N/T engine.

If you really do have a GST, I agree with Matt. I daily drive mine and run a 14b, in the past I've used both 6cm and 7cm turbine housings. There is a big difference there. The biggest difference though will be when you start tuning and raising boost. The 14b really comes alive at 18-20psi, but don't try it without fuel mods and something to tune with.
 
550s-650s: what is this?
SAFC: I have no clue what this is
Intercooler or water injection
14b to small 16g : Huh?
stock piping : I nkow what this is
stock maf : I know what this is
walbro 190 or 255 fuel pump : I know what this is
Thats about it

If done well, this setup is VERY "sleeper".

Is that a list of all the things I need to get and what is "sleeper" ????

Your best bet is to read up on these as much as you can. Type into the search those words and this site will help you understand in as much detail as you can handle, bar none! Study installation and tuning of these elements, too. Or find a reputable shop if you have the money to spend.
 
Reading is half the learning. I'm new to the scene too but have done all maintenance and upgrade myself thus far. I spend about 2 hours a day on average for the last 8 months reading these forums to learn as much as possible. I have much to learn still.
 
550s-650s: what is this?
Fuel injector size, measured in cubic centimeters per minute.
SAFC: I have no clue what this is
Apexi's Super AirFlow Convertor. Modifys the amount of air the ecu "sees" going into the engine. This allows using bigger injectors to deliver the same amount of fuel, allows more peak airflow to occur before fuel cut happens, and as a side effect advances ignition timing because the ecu "sees" less load. Must be used with a datalogger to ensure a good tune.
Intercooler or water injection
An intercooler is simpler to maintain and all you should ever need with the power level you are looking for.
14b to small 16g : Huh?
The 14b turbo is the stock turbo on 1G 5 speed cars. The various versions of the 16G turbos were used on the mitsubishi evolutions, the "small 16G" was used on the Evo I.

Already covered, but I think of a sleeper as a car nobody would ever expect to be fast, one that doesn't show any signs of serious modifications.

You need to do a LOT of research before you start buying parts. This site is loaded with all the info you'll need.
