Remapping Higher Mileage Cars - Worth the Risk?
Is it worth it? If you add another 50+ bhp then it's bound to put more stress on components. I've got a 2001 WRX (85,000 miles) that has been really looked after, serviced every 6000 miles or so without fail from new and while the extra power is tempting me towards getting it done, I wouldn't want to sacrifice reliability. Is this a reasonable concern or would most of you just go ahead and get it done?
I'm not concerned about things like brakes, tyre wear occurring quicker, more fuel being used etc but I am concerned about destroying the engine!
Any thoughts would be good, thanks.
P.S - Car is standard apart from a decat exhaust and K&N Air Filter.

Mostly depends on more factors,but usually is if its maintained well,if serviced too is done on time,but mostly if its healthy enough.
I would recommend ask your nearest Subaru specialist for check(AFR,det and compression),if you car pass this i would say why not..

Oh btw I forgot to mention the mileage it's 85,000

Bug WRX left the factory well crippled power wise so as not to get anywhere near STi territory.......a well looked after car with those miles should handle it with ease.

I drove a 53 reg standard STI a little while back and that certainly seemed to accelerate quite a bit faster so it would be nice if it could feel similar to that, not that it's boring atm!

Mines at nearly 100k, just had vf30 ect fitted and going really well at the moment. I did have a specialist check it over first, did compression test.
I also put a full cambelt kit and oil pump on as a precaution before hand, cambelt was due soon anyway.

TD04 on your car can be mapped to 265 BHP with filter / sportscat (280 at a stretch) which brings it into STi territory. Opensource mapping will be a breeze.
STi's can be mapped with ease to 330 BHP which reflects the kit......engine / drivetrain / brakes etc on the STi.

My previous classic had 128k on it ,when i bought it ,but it had full sevice history. After a few subtle mods and a different turbo it went from 215 bhp std to 316 bhp.,and maintained it for 10k after that,and drove without a hitch. If you think that a prodrive ecu on your car, can take the power up to 240 -250 bhp std ,then 50bhp+ should not be a problem if car has been well maintained.

Also bear in mind wear and tear is partially proportional to how long the engine spends at wide open throttle under maximum load where stresses and wear are at their highest.
For example a 500bhp engine that spends its life tootling at 50mph all day and only sees the redline once a month could last an eternity. As part throttle cruising probably only needs 60bhp so during this type of use, wear and tear is almost non-existant.
But a 350bhp engine using the same components that is regulaly ragged every weekend may only last 50,000miles, because its stressed alot more regulaly, and hence wears quicker.

Choose your mapper carefully, a friend of mine recently found out a £300 OS remap turned into a £3k rebuild, car had 47K on it.
I used the same mapper (JGM)to map both of the cars i have owned one is excess of 400bhp, although the engine is no longer in my car its still going strong and about to be mapped again in the new car.
There seems to be an influx of OS mappers and only 2 years ago some where paying the more experianced mappers to map their cars. Go Figure lol.

85000 isnt that high a mileage tbh - if well looked after it will go for years and years even at a higher power level. Mapped lots of bug wrxs with over 100K
Agree with 71/200 - choose your mapper wisely
