I've been a little apprehensive to even post this topic in the first place, fearing 'search noob!' responses. :) I have searched and tried to find the answer I'm looking for, but have had little luck. For one, I'm not really sure what to search for. But anyway, as the topic says I'm looking to get about 215 whp with ideally as broad of powerband as possible on minimal mods. What I currently have/planned (some parts aren't installed yet/bought yet):

-T25

-Stock SMIC
-Hard UICP, LICP
-Hard intake pipe (haven't bought yet)
-K&N Cone Filter
-Greddy BOV
-Stock 2g TB, Intake Manifold

-Stock 2g exhaust manifold
-Ported Evo III O2
-2.5/3" DP (haven't bought yet)
-No catback (haven't removed the 3" on there now yet)

-Stock Fuel system

-DSMLink v2
-WB O2 sensor (haven't bought yet)
-Boost, etc gauges

I think that's about it. I appreciate any input. Thanks.

Edit: 2g AWD btw.
 
You could also put an exhaust on it if you dont already have one, confused by your post. Buy a boost controller and raise the boost up a little bit. I would say ~15 lbs or so. Oh and if you are going to get that BOV and intake pipe, make sure to recirculate.

Start with free mods:

1: Hack Aircan and Intake Area
2: Clean Throttle Body
3: Verify that WOT is 100%
4: Check IC outlet Pipe for Corrosion
5: Open up the Fender Liner
6: Clean the Intercooler
7: Remove the BCS Restrictor
8: Check Base Timing
9: Valve Cover Vent Breather
10: Pressure Test the Intake

After the free mods, start with the following

(275-300 hp)

1: Manual Boost Guage
2: Intake Pipe and Filter
3: Boost Controller
4: O2 Sensor Housing
5: High Flow Downpipe
6: High Flow Cat/Straight Pipe
7: Cat-back Exhaust System
8: Fuel Pump
9: Intercooler Piping
 
You can't get anywhere near 300whp from a T25 force fed, it just can not flow enough air to support that. My car dynoed at 219 wheel on a T25 GST about 2 weeks ago, 75 degrees ambient in Michigan, high humidity. Yours will be a bit harder to do since yours is a AWD but you should be able to get fairly close.

My setup is:
-Megan O2 housing
-3" O2 back (catless)
-Boost controller (15 psi)
-Intake with K&N filter
-Hard UICP (Dave brode and Dejon for the 2 pieces, 1g bov)
-Greddy FMIC
-190 walbro
-550 FIC injectors
-SAFC tune with a logger and wide band

You should be at your goal or very close to it with similar mods. Make sure you have no boost leaks and your maintenance is up to date before you do mods though. Good luck!

I didnt mean to say that just those mods would support up to 300 hp without a turbo and injectors. I should of rephrased that a little.
 
Buy a supra smic for 75 bucks. If you're not planning on taking the car any further don't spend 500 on link just buy an AFC1 for 120 bucks. Wideband is great though, well worth what you'll pay for it.

Other than that port the fuck out of your O2 and manifold.


Evo injectors can be found for about 100 bucks if you look hard enough, so can a Walbro pump. Also, pick up a logger to monitor fuel trims etc...


For like 500 bucks you'll be ballin.

How are any of these free mods.... Only number is a "mod"

Your focusing on 1g's anyways...


This has got to be bench racing....

Sounds like he's asking for suggestions. Not that all of these have been covered a million times before and this is a super repost to the max. :chair:

I beg to differ to an extent.... He says he doesnt even have some of these parts yet.... Thats like saying how do I get 500whp, I have an AWD car... Whats next...:p

If you cant get 200 or 210 whp out of a turbo-charged car, you shouldnt own a turbo-charged car...
 
Trust me, there are many factory turbo cars that can't hit 200whp (mazdaspeed protege, 90's turbo legacies, etc.). The fact that he's trying to do this on a stock turbo is the main limiting factor on a DSM though. OP, as I said, if you use a similar mod list to what I said and your engine is in good condition then you should be able to meet your power goals. And to respond to what Gamble said, I've always been curious about the effects of cams on a T25. I think 264s might actually make a very good addition to the turbo, it can't hurt to try.

I guess I should've included more information in my first post. I just didn't want to start off too long winded. The car is being set-up for road racing, in particular NASA's Performance Touring class (I have a build thread going on here). Basically, classing is points based as in every mod is assessed points (ex- boost controller is 4 points, non-OEM brake calipers are 2 points, etc). Every 20 points moves the car up a class. Furthermore each class has a maximum weight/power ratio. My target weight and class limits me to approx 210 awhp. I didn't just randomly make that number up. :)

That said, I'm looking to make only as much power as I can without 'sacrificing' points that I could use elsewhere (tires, suspension, etc.) I'm also stuck with the t25 as any aftermarket turbo requires automatic dyno-reclassing.

You could also put an exhaust on it if you dont already have one, confused by your post. Buy a boost controller and raise the boost up a little bit. I would say ~15 lbs or so. Oh and if you are going to get that BOV and intake pipe, make sure to recirculate.

Sorry for the confusion, I do already have a 3" catback (not sure of brand off the top of my head). I just figured I could ditch it in favor of weight savings. As it will be a track car, I don't really care about noise too much (some tracks do have db limits).

Boost controller is a big 4 points, but looks like it will probably be a necessity. I already have the BOV recirculated. The parts I don't yet have are the ones indicated in parenthesizes in my original post. The others I already have.

force feed, he wants 210awhp, not 210 chp.
True. I'm looking for 210ish at the wheels. I know what the stock ratings are. :)

Dude, slap a 14b on there and some evo injectors and you can do like 250hp easy.
I would love to just throw a 14b on there instead of the pos t25, but I can't as I (tried) to explain in this post. Hope it makes sense.

I've read all the upgrade paths. And as your post shows they're set-up for a much higher goal than I'm looking for. Not to mention most of what is listed has already been done.

You can't get anywhere near 300whp from a T25 force fed, it just can not flow enough air to support that. My car dynoed at 219 wheel on a T25 GST about 2 weeks ago, 75 degrees ambient in Michigan, high humidity.

Thanks for this post. I tried to find past posts with these types of numbers with a mod list, but wasn't having much luck.
As for my build, pretty much any fuel related mod cost (fuel rail, injectors, pump, etc) is 2 points. So if I touch one part of the system, I'll probably just go all out on the rest of it since I'll be taking points anyway.

Dude, put some cams and a evo3 intake manifold and evo3 turbo manifold on there. See how far you can get out of the t25 hp wise.
Sounds fun. :) ...To try to show my perspective a bit, intake manifold is 1 point, cams are 6 points and exhaust manifold is 2 points. I would be willing to pick up a $500 SMIM over a $100 exhaust manifold if it were going to show similar gains due to how the point system works.

I'm not saying that the intake would be worth more, just using it as an example.

Buy a supra smic for 75 bucks. If you're not planning on taking the car any further don't spend 500 on link just buy an AFC1 for 120 bucks. Wideband is great though, well worth what you'll pay for it.

I already have Link.

I see where you're coming from, but it's been hard to find what I'm looking for as far as information goes, considering the direction most DSMers take their cars is different than myself. Normally I'm all about going overkill on things, but I don't want to take points unless I absolutely need to in order to meet my goals. I hope this makes sense as well.

Sounds like he's asking for suggestions. Not that all of these have been covered a million times before and this is a super repost to the max. :chair:
Probably true, but most people aren't limited to what power they can make.

lol. It's not like that, I swear. :eek:

Anyway, I appreciate all the replies and hope that I may have cleared somethings up in this post. Thanks.
 
OP, theres a very easy way to avoid the boost controller points. Take the little pill out of the BCS, on my car (with 3" turbo back) this gave the exact same result as a Joe P. MBC.

For your intercooler, you honestly should be ok running the stock IC under 2 condition:
1) You have the factory ducting in place. The ducts are CRUCIAL to having the maximum efficiency for any intercooler
2) You run less than 15 psi on your T25. I've logged air temperatures (at tb with a gm sensor) at various boost levels on my T25 and let me tell you, past about 14-15 psi, the efficiency drops like a rock and your intake temps will sky rocket. You might not see this with a logger since the output is from the measured air temp at the intake (by your maf) but trust me, its insane.

For the intake manifold, you should be more than ok with an oem one. You might get some use out of a cyclone one or a slightly worked on oem one (you can try extrude honing, I've heard of people having good results with these) but honestly, the stock one should serve you just fine.

What is this point system?
If you fart while driving, does that count as a point?

OOOO I see how the point system works now.
No. Just double checked. I think that's on the list of no-points mods. :)

I think that might count the same as just running a boost controller. The wording reads:
15) Aftermarket boost controller or modification/alteration of OEM vacuum lines that serve to
function as a boost controller +4
Yeah, I don't have the stock smic ducting, but was planning on making some for that, my radiator and oil cooler. As for the intake, I figured that the stock one should be good enough. I was just saying that I would rather take a lesser points mod over a greater one even with a higher cost. Thanks again for the input.

Edit: Although the Cyclone may serve nicely to maximize the power band. Ideally I would just have a flat horsepower curve from like 2500 rpm to redline. :)
 
Horsepower will dip as you go above 5000, its just a matter of fact when dealing with a T25. You can make very good torque though, most likely 220+ in the lower rpm range after spool (which will be almost instantaneous anyways).

For the boost controller thing, they say an "alteration of OEM vacuum lines". You wouldn't really be modifying any vacuum lines, this more applies to how people get more boost out of FD's I think. Its only cheating if they catch you, right? ;)

For your intake, one thing you can do is to break the weird jb-weld like stuff by the bov recirc pipe and pull it out. Do a angle cut on that tube to make it exactly even with the inside of the pipe. I did this with a dremel with two heads: one cutting disk and a grinding wheel. Glob some JB back on it, stick in the hole and let it dry. Looks completely stock and you open up a major restriction in the OEM intake. With a good drop in filter or cone filter+maf adaptor, you should see 90% of gains you could get with a full aftermarket intake.
