Subaru Impreza 5D 1.5R


Recommended Posts

It's not advisable to mess around with the ECU now especially when the car is still so new.

 

Few years back, there was a batch of N.A. subaru cars, affecting both the Imprezas and Foresters with a under-performing ECU mapping. At slow speed, the car will stop accelerating momentarily even you gassed it, afterwhich it will surge forward. M.I. was in denial of the problem but subsequently a new ECU mapping was re-programmed as the cars returned for routine servicing. Those who couldn't wait, spent unnecessary money to re-tune, add piggyback ..etc.

 

Damn... that really sounds like my car.. sometime floor the acceleration already also move very slowly, then will suddenly surge forward. But then this is already the 2nd year for my model.. any problems should have been resolved?

 

Anyway, can anyone here give me a brief lesson on the type of exhaust for cars... eg what can we change? For example, for bikes, I know we can either change the end can for better sound but not much increase in BHP or change to full system for better BHP and need to tune.

 

For car exhaust is it the same concept? Like mufflers and full system?

Technically they work the same way but for model cars it is more complex because of the catalytic converters.

 

The most effective way to regain some power is to either get a high flow cat or remove the cat. One is expensive but legal, the other is cheap but harms the environment. Your call :)

 

Go to the M.I. at TP, they have a very nice muffler for your car. :p

Don't go to the showroom. Go to the cashier where owners pay for their servicing. Looking at the cashiers, the muffler is right behind you, price about SGD1,600.

hmm i think u mind abt ur low end alot...

 

lets see " will exos and drop-in improve" = yes abit...

 

de-meow exos on auto = abit

 

lighten ur car by removing junks, not stage 2/3 pls = abit

 

not fetching anyone = ALOT! :lol:

 

ok la jokes aside, tuning will still be best if it's done on a relatively new vehicle after run in as compared to 2-3 yr old car with lets say 50k above mileage. mainly is becoz the car parts are all NEW! so lesser worries on after tuning side effects as compared to the older cars where some are replaced with new, while some is still old etc etc... tuner will also feel safer working with a new car or a car where they know the condition well enuff to do a full tuning limit on the vehicle.

 

And for now ur list is short... it will be good to last u for 1yr or maybe abit more then u will start damaging ur wallet again :lol:

 

But if u intend to tune, dun need the pivot thing la imho.. tell the tuner u wan ur fc and some improvement on the low end and from there u work out with him. But always remind urself abt the purpose of the vehicle, so u wun end up losing a big hole when u selling off.

Hi guys, saw the exos specially built for Subaru 1.5R AT. It's called Syms & it's semi flow. Like the earlier post, AT cars need the back pressure to run smoothly unlike MT cars. I was wondering & if anyone has any clues on what improvement does a semi flow exos like Syms would provide? I'm driving a Subaru 1.5R AT & I have to agree the pick up is really sluggish.

 

But I've recently went to kl and tried the car at speeds of 160-170km/h. I can say the car is incredibly stable like as if I was driving a continental car. Even a Japanese 2.0 car that I drove is not as good as Subaru 1.5R handling. So rest assured that handling and safety for this particular car is above average of most jap cars.

 

Back to the topic of Syms exos, can anyone with the expertise on exos give a clue on what improvement would I gain if I were to install it. I'm in a dillema on choosing between Tanabe(a straight thru exos) versus Syms(a semi flow exos). While many have said that Tanabe will make me lose on low end, they also say that Syms won't make lose low end. But the question is, what improvement can Syms give?

 

Some even suggested that I change to Tanabe and also change to CAI to compensate the low end. Do you think this will work?

 

So now it's whether I should get Syms( which I have no idea what improvement it'll give) or get Tanabe exos with CAI to compensate low end. I hope you guys can help me diffuse this dillema and giveme a rough idea on what is what.

 

Please do reply, I'll appreciate any comments/feedback/suggestions.

 

Thank you

CAI will not compensate in ur case.... that exos need to match with upgrading some of the fuel system parts.

 

ur fc will definately be gone case..

 

Full straight

rex injectors

rex pump

drop-in filter

remove spare tire and junk at ur boot

tune it leaner

lightweight rims

 

these shld can feel some difference before u start to tear away ur all ur water tanks engine.

If you start having all these mods, not only your FC is gone case, engine reliability also gone case.

 

Even with all the money in the world, the performance improvement is still limited simply because the engine is only 1.5litre. As the saying goes "there is no replacement for displacement"

 

If you want a fast car, start with a fast car.

I have to agree with you. 1.5 litre car can't give much thought when it comes to performance. Best is to enjoy the ride and exploit whatever ability the car has to our advantage.

 

Thanks for your feedback guys.

Humans can be stubborn when all has been said about the limits of a car. They would still go install exos, de-meow, CAI... And I fall into that category of humans. Hehehehe....:angel:

anyway, Ian, where did you fix the meter gauges in your car? Any recommendation? Went to Silent at Commonwealth... large selection but kinda expensive... any other reliable place? :)

 

i got it done up at Car Beauty at Eunos Industrial Park such gauge are costy imo but of cos i am using Pro Sport fr Taiwan not Defi which definately cost times more.. well once in a while there are forumers in e scooby forum letting off their used gauges at reasonable price. Back to e qns wht kinda brand n gauges u are lookin at?

 

My advice if u wan something tht look neat n diff well perhaps u might wan to consider this below:

http://image.nengun.com/catalogue/primary/nengun-0662-00-defi-defi-link_display.jpg *PLACE IT ON THE CENTRE OF UR FRONT DASHBOARD OR ON THE TOP RIGHT CORNER OF UR WINDSCREEN NEXT TO UR PILLAR

*PLACE IT UNDER THE IU UNIT NICE AND NEAT (CAN GET FR CLARKEWAN)
