Well everyone finally got the misfire sorted (coilpacks) and the wrx is running great, but what engine (power) mods would you do next its a jdm impreza wrx 93, and has had a full engine rebuild and full decat and apexi exhaust bailey dump valve, upgraded brakes on the way and is at 1.1/1.2 boost and just had a service???

 

Budget? Forged? Power aim?

 

Earn money, bin the Bov!

 

+1 bailey notoriously bad valves ive heard ? get standard recirc on there or forge motorsports ? has it been mapped yet ?

 

£1700 spent on the engine but not sure have bill and work somewhere no map as yet and what wrong with the dv

 

Its a Baileys, its just bad.

 

300-350 ??

 

1700 seems very cheap for a rebuild ? but if you want 300+ then a new turbo ,fuel pump,bigger injectors are needed . and panel filter /induction kit .

its brand new ****

 

baileys seem to create issues rather than solve them, id lose it personally

 

Sounds like a standard rebuild, the parts alone for a forged rebuild would set you back nearly 1500 quid, so you need a new ecu and get the car mapped, 320bhp nice and safe for now

Will just be a STD rebuild, not that expensive anymore.

the 93 WRX has the TD05 turbo which is more than capable of 300bhp, so I would do injectors, fuel pump, panel flter and remap although you may well be pushing the limiations of the tiny WRX intercooler

Ditch the Dump valve, they are toilet..... just money for a noise and the bailey ones are notorious for giving bad running problems, they stick open and all sorts.... sell it or send it back!

Out of curiosity how are you running 1.2 bar on a std ECU without a remap? you got a bleed valve fitted?

 

Omg - don't mention bleed valves! Please tell me you haven't had a 1700 rebuild and fitted a bleed. That aside are you still not running the engine in?

as said bin the baileys. mine kept sticking open and dumping boost. got a forge and its been spot on ever since.

 

I know man, one way ticket to an empty bank for ever!

 

cheers lad just what boost the gauge is showing in 5th

 

If it's not been remapped mate and it is already running 1.2bar then you are in for a world of excitment when the colder weather sets in....... If you like being slammed in to walls!!

the Fuel cut on the STD ECU is 1.25bar I think so when the temp drops you'll creep in to that for sure and boom there it is, fuel cut........ that's providing the boost gauge is reading accurate, it could be wildly optomistic LOL

 

right! what would you advice in my prob its my first sub and i want to enjoy her for a while????

 

to be honest I would ditch the BOV, and ask someone if they can lend you a boost gauge, just to make sure yours is actually accurate..... if it is accurate I would try and find out why it is running so high on boost, the std WRX runs at .8bar IIRC and will creep up slightly after a decat but it won't be anything like .4bar increase....

Are you sure the previous owner didn't have it remapped ?

 

nope the last owners didnt look after her at all so ????

 

Like I say, beg, borrow, steal someone elses boost gauge and make sure yours is right and get it booked in for a remap sooner rather than later or you'll be another £1700 lighter mate!

 

i am nearly sure it works was in my last car and the boost was worked off it but at 1.1-1.2 is that dangerous seen motors (Subs) at 1.6 boost??

 

You will have seen imprezas at 1.6 bar frequently, but they all had stronger engines than you've got and they were MAPPED for it...... anything that significantly alters the air flow in to the engine or the gas flow out of the engine needs to be mapped for, it's that simple mate.

Any dipstick can raise the boost on the car with a bleed valve but that is just daft, it's the clever mappers on here that do all the trick work behind the Boost raise that keep the car safe, like altering timing, fueling, checking for knock at the higher boost etc etc.....

Unfortunately the impreza isn't like a Ford where you can just chuck mods at it and it will run seemingly fine forever, it HAS to have mods catered for mate or you are going to blow it to bits.

If a car that should be running .8bar is running 1.2 bar you no one knows why, this isn't a good thing....
