New GSX (sold 340 WHP WRX) What to do on a DSM to get 275-300 WHP?

[Aecannon]

Okay I just sold my 02 WRX that delivered 340 to the ground (built it myself , I got a GSX now, love the AWD action but the DSM styling is MUCH better... SO what do I need to get to about 275 to 300 to the ground? You guys tell me which....

Turbo (prefer about 3k spool-up time)
Intake (forget looks, I want the power)
Exhaust (you guys know a good turbo-back (the best))
Fuel Upgrades (need to be controlled by.....(look down))
Plug n Play engine Management (piggy back fuel/timing, any staged upgrades with matching turbo/fuel/intake/exhaust like WRX tuners did?)...forget safc, itr doesnt controll timing
Intercooler kits (Front mount)
Straight pipe
Clutch
Anything else you guys would reccomend would be appreciated. By the way, what are the stock internals able to handle (33k on my engine)? What is the stock turbo's limits and efficiency range? Here's what I don't want to do...Detonate and blow this engine, have high EGT's and melt parts, basically take the wrong route...So before I even touch the boost, bolt on an intake/exhaust/turbo/injectors I wanna know what the pro's (you guys) have to say about all this. Im sure the big boys on this forum know the best route to take to get 275-300 WHP to the ground safely and reliably. Thanks guys, look forward to hearing your opinions. Nice to be a DSM guy. Man these things are sexy....

Check out the tuning guide, they've got the best of the best for each catagory you're looking for. I'd go in this order..

Boost Guage
BOV
MBC
Intake
Wheels and Tires (17x7, 17x8 18x8)
Exhaust (Cat and Catback)
Downpipe
New Turbo
New Exhaust Manifold
New Fuel Injectors
New Fuel Pump w/ rewire
New Intercooler w/ pipes
Computer management

I'm a DSM noob, but that's my schedule so far so take it however you will..

ANyone know of a good performance shop in the DC area? DOnt say new again....they suck sooooo bad. (I know I used to work there)

you should be able to get 275whp just off of the stock T2small turbo.

For fuel and engine management get the DSMlink, www.dsmlink.com
You must buy a 95 EPROM computer for this tho, your 99 computer will not work. go read up on it tho, theres nothin that even compares.

 

[red91tsiawd]

t28 turbo, decent intercooler, 3 inch exhaust, k&n filter, 1g bov, good intercooler pipes, 550cc injectors (rc's are cheapest and work fine), and a apexi afc

 

[GSX4LIFE]

I would of course put a boost guage on it first. from there hear is my list, at your request, for what you think you may want.

MBC: Extreme XBC
Turbo: AGP T28(Or wait for the L1R)
FMIC: Victory performance. (I like this one now, because it gives you the piping all the way up to the TB. Just buy a 1G CBV, and your set.)

Exhaust: DSM performance 3" Eliminater DP, with test pipe ore high flow cat. Thermal cat back.

Intake: 3" dejan tool w/ any conical filter.
Fuel: Walbro 225hp pump, dsm performance 650s, SAFC, and some sort of regulator.(prbly a charged air on a 1G rail)

Wheels: Get TE37s if you can afford them
Tires: I like the BFG GForce KDs

Drivetrain: ACT2600, or CM2500 clutch, B&M short shifte, Simborski bushings, Extreme stiff shift kit.


Thats all I can think of right now. Oh BTW, get a pocketlogger. Forget O2s, forget EGTs. Timing is the only way to tune IMO.

This is my personal view at a combo that could make decent power. There are many other combos that will do the same.

 

[DSMTurboEclipse]

ditch the stock turbo and stock BOV for sure, i'd suggest you read the tuning guide. it helped me out alot too. good luck

 

[DSMu4ia]

Turbo:

16g (small, just port the exhaust housing a bit).

Intercooling/Intake:

IRC 2g Race Kit with piping matched to whatever (1g) BOV you chose. Get their J-pipe if going with the 16g above. K+N Intake, 3" Dejon Intake Pipe with Reducing Coupler.

Exhaust:

2.5" 02 dump, 3" turbo back.

Motor Work:

Stock 2g motor/head/cams/intake mani. is fine.

Fuel:

660's, DSMlink, Supra Pump, Buschur Bolt on AFPR

Porting, etc:

Ported 2g exhaust manifold.

Gauges:

Boost, EGT, Oil Pressure, Water Temp.

Drivetrain:

ACT2600, 2g clutch disc (OEM), Center Diff Upgrade (Speed Design).

That's all you really need to have 300whp reliable on pump gas.

To get it to the ground, add your choice of suspension.

Should be able to get right around 106mph traps with ease on pump gas, and upwards of 110mph on pump gas. Should see a hair over 110mph on race gas, but it depends how brave you are with tuning.

Expect a 12-second pump gas car.

Your welcome.

your joking right?

 

[got traction?]

hey look its the fastest floor in sanford gracing this board. What dustin you dont believe 275whp is capable with a t25?

 

[TSi92]

o2's is almost worthless but EGT is a must.

I have no experience with this shop, have just seen them because I was looking for shops in MD, but Extreme Motorsports looks like they know what they're doing. www.extrememotorsports.com

i thought 18"s were bad for a 'go' car....

no, if you have all the supporting mods, it can be done. Ask larryd. But then you put a bigger turbo on and you'll make WAY more power.

 

[STARION]

you asked about performance shops around here......MachV (specific to DSMs and WRXs) is in arlington, or maybe its on the falls church side of the border; either way, they are close and good. There is also CDE motorsports (never dealt with them), there is Vertex in springfield (I wouldn't buy anything from them besides a gauge or something). Then in maryland you got Extreme motorsports (DSM specific).

Fortunately this is a pretty good area for us DSM guys. Hope this helps, glad to see another local DSM guy, maybe I will run into you sometime.

I agree! 275 crank hp might be possible, but not at the wheels. I dynoed my old T-25 at 220 whp with supporting mods. If it was 275 whp that would translate into about 320 crank hp. Theres a big difference between whp and crank hp.

Correct! If the 18" wheel and tire combo is heavy which most are, then it will hurt performance. Every pound of weight that is taken off of a rotating mass is equal to about 8 pounds of weight being taken off of the car else where. The same principle stands for lightened fywheels also.

hmm... what a concept! K, here's another question... what if you do have 18"s and slap on say some 16"s on the front (which are of course lighter)... would that help any? Im almost sure it would... but will it make a big difference or will the 18"s on back still screw it up?

Yeah... I would tend to think that it would help since the front wheels are the ones that are doing the work anyways. If you had some really light weight 18" wheels then it wouldn't really matter. The only thing that would be out of spec would be your speed odometer, because of the circumference of the wheel and tire combo. You could probably get it recalibrated though. I currently use 16x7 Konig Villains with 225/50R16 Nitto 555R drag radials. This set up seems to work pretty well with my FP ported Big28.

ask me what.. aint no way your gonna make 275whp on a T25 without nitrous.. I made 222whp with every bolt on except the FMIC at 23lbs of boost.

T-25 @ 23lbs of boost, no wonder why.

 

[larryd]

yeah it made a wopping like 15more hp at 23lbs then it did at 15lbs.. but the torque difference was like 60-70ft/lbs.. pretty neat stuff.

Maybe the HP on his sheet wasn't WHP? 275 might be close if it's not WHP we're talking about....
