Question Best bang-for-buck mods (not just cheap)?

I never thought it would happen, but the mod bug has bit me just a bit since getting my WRX.

I've done the intake silencer removal, and the K&N drop in filter. (Thanks Jorge, but didn't do the airbox hack. Did the rubber elbow air intake tho.)

I want a streetable reliable car. Don't need a 12 sec. drag racer. But a little more power never hurt!

Until I can do the research and get the knowledge to wisely spend real bucks on chips and such, what would you suggest? Give pros and cons. Not to be duplicating the earlier "cheap mods" thread, I'm looking at value for money spent, not just cheap. Say, under $500 for now.

Not a hardcore gearhead, but not totally clueless. Can do some DIY.

Yes, I have done a search!

One thing I've been considering: an MBC like the Dawes. Yes, I know I need at least boost and EGT gauges to set it properly and not ruin the engine.

Also considering a few books: Building Horsepower, Modern Engine Tuning, Maximum Boost. Someone mentioned a book called Training WRX (?). Where do you get that - small publisher I'd imagine.

Training WRX you can get from Mastro Subaru (www.mastrowrx.com). It's an MRT book and they sold it to me for 12.95. It's worth it, especially the suspension chapters.

Bruce you already know what to do

Air filter

MBC

Boost gauge

EGT gauge

Shifter bushings (Kartboy / Cusco)
Id just do the bushings and keep the stock shifter.

Keep in mind that its not the higher overall boost u need. Its higher boost in first and second gear that makes biggest difference. Wakes the car right up even with stock boost levels.

Thats what i did and im VERY happy with the results.
I picked up about a half second, about 2 tenths in my sixty footers, and almost 5mph with just those mods. Way worth the few hundred bucks it cost me.

15psi in first and its a whole new car.

Under $5oo and you too can have a 13 second suby

I am not very knowledgable about mods but that book sounds like it might be a good investment for me.

Just a question, but how would a boost gauge effect your power??

It just shows you how much boost you are using.

Under $500 good mods would include exhaust, (some catbacks are around $500), new air cleaner.

Blitz has an exhuast and air cleaner for the WRX, dyno tested the cleaner added 11HP and the Exhaust added 13HP. These were gains that were to the wheels. See the new SuperStreet for their Project WRX.

If you can, get a boost controller, that will help alot!!

You might think about getting a Unichip from TurboXS.

www.turboxs.com
http://www.turboxs.com/turboxs_2002_...ge_1_hp_vs.htm

It`s similar to what Brandon was talking about, but better. Do a few searches and you`ll see what it`s capable of.
Mark from TurboXS is awesome. Give him a call and tell him what you are looking for.

TurboXS Customer Service 1-877-231-3235

I love mine and have been driving with it for almost 7k miles and I`ve never had a problem.

Bruce I ran 13.9 with my setup already and spent about $3oo. You WILL NOT run 13.9 with a cat back and an air filter, i promise you that.

A Unichip is $700... a bit over the $5oo ballpark you were talking about but it is otherwise a great mod.

Scooby14 what have you run with a cat back and a filter so far?

I don't have these mods on my car, I was just suggesting them due to the fact that SuperStreet is building a WRX. I'm not disputing the mods that you have, just making some suggestions!!

Right, sorry about that. I missed the $500 limit. It is definitely worth the extra $200.

A chip could well be in the future, but as noted it's too expensive for now. She Who Must Be Obeyed has a lot to say about expenditures, and we have sunk a truckload of $$ into an addition to the house. It was a miracle that I could buy the Scooby!

As a latecomer/newbie to modding, I want also to do some research and get some knowledge before spending for major mods. Lurking here and on the WRX board has helped a lot. I want to do DIY modsn for now, not just for economy, but to learn - without blowing the engine.

Maybe I should have mentioned that what got me thinking of this thread was a discussion here about exhausts. Someone said that there were better places to put your money than an exhaust as far as performance went, on a value basis. (Sound is another matter, of course). So it got me thinking. Especially since, like many other relative newbies, an exhaust seems like a good first mod if only for the looks and sound. But a turboback is as much or more than a good chip.

Anyway, now that I have over 5k on the car, the stock exhaust seems to have gotten more assertive sounding! I'm told that it's not my imagination.

Enough of my free-associating. Keep the ideas coming!

Hmm I was just wondering how in the world does a boost and EGT gauge make your car faster? I don't know that's just beyond me, then again maybe I'm just stupid? LOL please respond back I'd like to hear your theory.

I think an exaust is the next step beyond what i have done so far. If money wasnt a concern id probably get a chip. but i can deffinatly do without for now. Im probably going to leave it at that till next spring. Im happy with it now.

I bet you will be satisfied with just the mbc and filter

You disconnect the factory EBC and therefore have to actually know how much boost your car is running. If you can monitor the boost level without a gauge, more power to ya, put the 55 bucks or so into somethin else.


Once you install the boost gauge you might notice that in stock trim the car runs about 9psi in first and second gear and about 13psi in 3rd 4th and 5th. It also bleeds off about 2psi above 6000rpm in every gear. giving you 7-8psi in the top of 1st and second. weak at best.

Once you set an MBC right you can get the car to make 13psi in all gears. It also comes into boost quicker than stock and holds it till the rev limiter. That alone makes the car much quicker.

Ask anyone that has done these mods

A boost gauge is pretty much required

.... at least thats my theory

Scooby14 I was just wondering if you were referring to the Blitz Nurspec exhaust muffler/piping? Because just for that it's listed at $440 dollars and that makes me wonder how much the full turbo back is going to be.

V6. Just wondering but what exactly have you done to your car/specifics? And how much have you spent?

Hmmmm yeah I know what you're saying, because a boost control can you give you that much more punch. Being able to control how much boost/at what rpms/and which gear will greatly improve your performance concidering how stock settings have to be on the stingier side. But that still doesn't answer my question of how a "boost gauge" gives you any power. That simply is the readout of the PSI being put out from the turbo.

You need a boost gauge with a MBC. Period. It in NO WAY SHAPE OR FORM gives you any more power. I never said that. You must have one with a MBC tho. That was my point.

I have an MBC, a boost gauge, a Uni air filter and an ILP shifter w/ kartboy bushings. I ran a 13.95, 96.53mph. I spent about $300

Blitz & 5Zigen are currently doing there part for the WRX. Blitz has a new boost controller called the SBC-id, and Stainless steal axle back & cat back exhaust. 5Zigen will also have a cat back exhaust end of next week. JIC Magic and Zeal are coming out with US spec full coil over systems in about 3 weeks. Already Endless has brake pads and brake upgrades for the WRX as well.

PM if you are interested in I-Club discount pricing.

Thanks!

I agree with what you are saying about the MBC and the boost gauge, just didn't see that you had posted the fact you had a MBC. I know you don't get anymore HP or power out of it, just get to contol the boost level for the gears that you need them for. I also wanted to put my .02 in about the exhaust and the LM air cleaner that blitz has done to the project car.

And yes, I am refering to the Nur SPEC cat back....they dyno'd it with 13HP gain.

Not bad.

I'm partial to the up pipe as a early mod, as it removes the cat closest to the motor and turbo, is cheap, and can't be seen by prying eyes. Its fairly cheap too. While its not really a power mod, it does pave the way to much better performance once other mods are done.

If one was to modify the exhaust and intake airflow how does the computer know that? Wouldn’t it be better to invest in a programmable computer before the other stuff? I am new to tuning computerized cars so someone enlighten me please.

for your budget, I'd go with v6's list or tires. MBC is the best bang for the buck power mod (set it and be happy). I run a Hallman and have not had a problem for over 6k miles.

here is why, cat-back is your whole $500 budget and you get minimal gains and later on finding a downpipe that fits or the same vendor that is willing to sell you just the downpipe is a pain. Up-pipe will be your whole entire budget also, up-pipe ~250, install ~ 200 again minimal gains. if you are going to touch your exhaust, save a bit and get the up-pipe and turbo back at the same time. don't waste your money on a catback.

if you are gonna start modding you need gauges, period.

Question Best Boost Gauge, EGT gauge?

I think I'm going to go for the mods V6 suggests. I've already got the turbo back 3" exhaust and I've an A/F ratio gauge as well. My questions are: What are choices for boost gauge and EGT gauges? I wonder if the single, gauge from Subaruparts.com which is installed on the steering column cover is the best for the money, also, what are the numbers that I should look for in the EGT gauge? Could I get by without the EGT gauge? I'm positive that without a boost gauge it is totally impractical to install the MBC, but I don't know about the EGT. For instance, would I have to have another bung welded somewhere in the exhaust system? I don't know where this EGT gauge would get it's signal.
Please forgive my asking, but I would not even beging to know how to do a search to specifically answer these questions.

Thanks,

Manuel

Apexi/Greddy/Blitz and HKS are what most people go for. Defi also makes a nice guage set up. I would stay away from Autometer as they are not the best units. You can "get by" without most guages, but the more information you have the better off you will be. The A/F guages are not very accurate unless you have sprung $1k or more for a wideband O2 unit. The EGT give you a little information as to what your A/F mixture really is. If it starts reading high your fuel system is most likely dropping out, and detonation and more problems are right behind. Guages are absolutely worth it when you begin modifying, and a boost and EGT are priority.
