what mods am i missing?

[peter535]

hey i have a 97 eclipse gst ,my mods so far are 3'exhaust , mbc , air intake , bov , intercooler , uicp , walbro 255 , afpr , boost gauge , wideband , act 2100 and flywheel.
so my next upgrade will be a turbo i was thiking of getting a 50 trim i just wanted to know what else im gonna need for the turbo i know i need injectors (650 cc?)and an safc. also what turbo do u guys recommend for a fwd car?
how much hp should i expect with this setup?

I would get a logger, dsm link or dsmap (not to knowledge'd with dsmap this) with dsm link youll have the ability to change you injectors by typing it in to the laptop, and you wont have to rechip it later. Get a set of 650(though on a 50 trim they wont be enough)750+ or bigger or 1000-1150cc injectors.

I had a 50 trim it was nice, on my awd i would break traction in 2nd, you being front drive, youll enjoy no traction till 3rd.

50 trim is good for 350-550 or so hp, its all about the mods done and the tune and condition of motor.

A clutch and lsd would be nice.

Yea if your going to go with a 50 trim then you should get 750's, and if you cant afford link then get a safc,keydiver ecu, and a datalogger. You might over power the clutch but i would wait and see.

Dsmlink should be your next mod. Its expensive but well worth it.

Injectors and DSMlink. As for a turbo, it just depends on how much money you want to spend. I've personally had good results with SBR, FP, & MHI turbochargers. I currently have an SBR turbo. I'll let you know about HP numbers when I get to the dyno.

I had a 50 trim with most of the mods you have now with 550cc injectors (yes I know a little small) I loved it. The 50 trim is such a beast of a turbo. Not too sure what kind of turbo it actually was... Ill have to find that out since I sold it last summer.

Look at the mods in my profile. There are a few parts in my mod list that are not needed but help make the car faster. I should be a little over 400whp with my mods.

I'm maxing out 550's on a small 16g. If you are going to push your turbo, I'm pretty sure you'll be needing more than 650's.

I'm assuming you're still running stock 2g stuff? Like the intake manifold, throttle body, cams, and turbo?

Here's what I would do: Get DSMLink, and learn how to use it to tune your car. You've already got a lot of mods that aren't necessary for the T-25, but the good thing is that you don't need to buy them to upgrade the turbo. Use DSMLink and see how much you can improve the car.

Hell, while you're at it, throw on a 1g TB. Not sure how much that'll help with the T-25 but you won't want to run the stock 2g TB with a bigger turbo. It's a pretty cheap upgrade, as well. Then I'd buy the injectors and get them dialed in. If you set the injectors up and get them running good, you won't have to make any changes to the dead time or global fuel settings in DSMLink when you do upgrade the turbo.

Then I'd probably do the turbo, followed closely with cams (and cam gears). Cams will help overcome most of the flow limitations of the 2g head and intake manifold. It's a little hard for me to recommend doing the cams before the turbo since the T-25 can't even keep up with a stock 2g engine.

A 50 trim can max out 750's if completely built.

 

[peter535]

thanks for all the info guys but do u really think clutch wont last? its the act 2100

 

[silver bullit]

Depends on mileage and condition.

 

[1992awdlaser]

It won't last if you get traction. Since you are fwd it might last a little while.

 

[peter535]

brand new its getting installed next week

 

[rarson]

I would probably buy the 2600 pressure plate and use that instead.

 

[peter535]

i can get 750cc even before i install the turbo?

 

[SnowBird]

A good set of rubber. Maybe some street legal slicks.

 

[mndsm1]

i can get 750cc even before i install the turbo?

i wouldnt put them in until u actually get everything your going to be putting into the car. your car can actually run a little funny if you do without a tune. definitely get dsmlink and something to log with. i personally would maybe do a intake manifold or somethin with a bigger throttle body

so if i get an safc the install the injectors and tune the car will i notice a difference in power?
like would it be worth it to pay some one to tune my car without the turbo and then when i get the turbo re tune it

 

[1992awdlaser]

You can put whatever size injectors you want on a car even if it is stock as long as you have something to control them like dsmlink.

Edit: You are going to have a hard time tuning 750's with a safc. I would get a chip for the injectors and then you caqn use the safc for fine adjustments.

 

[rarson]

Yeah, you can get the 750's or whatever injectors you want before you get the turbo. But I wouldn't get them until you have DSMLink, or some other programmable ECU to dial them in properly. They'll still work fine with the T-25 once you've adjusted for them, they'll just be operating at a lower duty cycle.

As far as an intake manifold goes, I think that's wasted money with stock cams. Definitely also a waste with a T-25. That's why I suggested the 1g TB as a cheap upgrade. 60mm is about the same size as most IC piping, so it'll be fine for a 50-trim (the stock 52mm though is ridiculous... 8mm really does make a difference!).

 

[rarson]

The problem with solutions like the AFC is you're just hacking the airflow signal. What you really want to do is adjust the injector firing time, because the aftermarket injectors aren't going to fire at exactly the same moment as the stock ones do.

DSMLink lets you adjust for this by changing the injector dead time. You also get a global fuel slider which changes the amount of fuel delivered. So if you know that you're using 750cc injectors and the stockers are 450cc, then it's a simple ratio to figure out what percentage the difference is, and there you go... you're getting exactly the same amount of fuel at the same time as the stock injectors, and still using the stock fuel and ignition maps (adjusting airflow with a S-AFC also changes the amount of timing you're getting, so if you lean the car out, you're also increasing the timing).
