i have a standard 95m wrx(apart from forge dv which i was told should be the first thing to chuck!? ) it has 84k with good history
i would like a wee bit more SAFE power and reliability is a must!
but i dont know where to start!
advice please??
cheers
jaye

 

A nice full de-cat exahaust system would be a good starting point. Dont worry about the dump valve some people dont like them. Does'nt cause any harm to your car.

 

how much you got to spend?

 

sorry it does have a magnex style back box,rest of system is standard tho.
got mot next monday so after that.........byebye cat!
would a front mount intercooler be a good idea at the mo??

 

im not on a tight budget.........but i dont want to go mental for the hell of it.
its just going to be a gradual thing,dont want to touch engine internals.

 

could anyone tell me the best oil to use?? was told 5/30 fully syn??

 

Hi, I'd go for a cold air induction kit and remap (in that order) for now and maybe a new exhaust system/catless up-pipe if your budget can stretch to it. If you can afford all of that I'd leave the remap until everything else is done.

I wouldn't consider the FMIC while you're still running a standard turbo as your standard I/C should cope with your current set-up.

 

Have a rolling road session before you start modding to pick up any problems with fuelling etc costs about £50.
Car should be running about 260ps but that was when it was new so a few horses may have been lost.
Standard internals can handle 300bhp and the turbo can handle 1.1bar boost easily (td05 can handle upto 1.4-1.5 bar but you did say you wanted reliabilty

 

Dont bother with an induction kit, you will lose power due to it sucking in cold air! You will only need to replace the original airbox if you fit a front mount intercooler.
Yes the standard TD05 handle 1.5bar BUT only if you have a full decat exhaust and a better intercooler to lower the inlet temp.

Realistically what you should be looking to do is,
Full decat exhaust.
Decent panel filter, i.e green, K&N etc (Not and ind kit)
Walbro 255l fuel pump.
Aftermarket ecu i.e Link, Gems, Apexi power FC, Hydra, etc

You should see around 280-290 bhp with these mods

The limiting factor will be the intercooler which wont handle over 290 bhp.
So if your wanting more than that, then you will have to get a front mount and replace the airbox

 

do you mean warm air

 

The biggest single cost is going to be the ECU. ESL do a mappable plug in chip that uses the standard ECU,which costs £600 fittted/maped.This is the cheapest option,but no worse for it. Before fitting,change the exhaust,and fit a panel filter.An uprated fuel pump is always nice for piece of mind. While your having the ECU mapped,fit a set of 440cc injectorsand later map sensor,and you'll be good for 300-330bhp.
As far as frount mount's go, their not needed until your into the 300+ range. The standard intercooler is restrictive after this point,and charge temps will start to rise.
Also,at this level your into gearbox death territory!

 

thanks for all the advice guys!.......i got in contact with a mate today who advised me 2 go for the uprated fuel pump,pannel filter,decat and bleed valve..................do i really need to mess with ecu??

 

You could fit a plug and play chip from polar performance,with the decat,filter ect will give you 285bhp ish. This will up the boost,make your car safe to run on UK fuel if it's an import,de-limit it too.The chips easy to fit,and cost £125-£150. I've got one,for the time being,till i go for the ESL ECU. It made a nice difference.You won't need a bleed valve,im not keen on them as they can cause damage.

 

great! that sounds like my best option..........chip,decat,fillter,fuel pump...............should i expect 285 from this??...........think my car is 246 at mo??

 

**** the bleed valve.
Fuel pump (maybe even a adjustable fuel pressure regulator if you can afford one) as the stock ones can be overpowered by fitting a newer/better fuel pump.
Don't get too hung up about power figures ,the driveability of the car on the road is more important imo.
whilst increasing the power is good a quick check of your brkaes may be in order as there are 2 pots which aren't too good

 

[QUOTE=Marx Mcrae;8000818]Dont bother with an induction kit, you will lose power due to it sucking in cold air!


Errrrrm....why would you lose power sucking in cold air? Cold air is denser and will therefore burn more fuel, that's why you have a mass air flow sensor to measure the flow and temperature of the inducted air so the ECU can adjust the fuelling accordingly. Also, if cold air reduced the engine power why do charged cars have intercoolers?

I had a cold air induction kit fitted to mine and it increased the power noticeably.

 

im not to botherd about power figures,i just like to get the best out of my car whatever i drive and as you say "driveability" is the most important thing.
but yes the brakes are shocking! had one of the front calipers off today,bottom slider was stuck!

 

A good susension set up will help get what power you have at the moment to the road.
Have a quick look in the 'suspension' section

911 and dunx seem to be 2 guys who give good advice on suspension upgrades (911 has a seriously quick hillclimb car ,think he posted some vids of it as well)
