Decided to get my car mot'd today as it's been sitting for 8 months now & this is perfect weather for it!

It's a 93 wrx import, got a full de-cat, apexi ecu, front mount cooler, td06 turbo (I think can't remember) otherwise pretty much standard.

Problem is when it comes on
boost around 3k it backs off
Like it's over boosting or lacking fuel?

I'll be honest I don't know nothing about these so I won't pretend to, I bought it on a whim last year as it was a nice car for money but need to sell it now. It passed it's Mot today no problems, so just that to sort on it now?

Thanks

 

More likely its got a TD05 fitted mate... likely to be a 16g standard unit, still good for c350bhp though.

What happens when it 'backs off' mate?? Who mapped the car and what boost has it been mapped to?? Do you have the Apexi Power FC hand held commander unit??

My mate had a simular problem with his, the boost pipe under the intercooler had cracked, quite a common problem with the early ones. Might be worth pulling it off and checking the pipe and gasket, its a plastic Y peice iirc

 

Not sure who mapped it but it's got a monitor on the dash that I've never touched & I know you can adjust the boost etc but it was fine before I parked it up, always does it around 3k in any gear

 

Yea, my first port of call would be to check all boost hoses... 3k rpm is around the point that the TD05 will be hitting peak boost.

My bet is either The MAF is shot or the boost controller on the drivers wing under the bonnet is blocked.

If you checked those, try the coil packs

 

P.S Want to sell the front mount or apexi before you shunt it on?
Can supply either a std ecu of top mount intercooler to replace them?

 

Got 330mm ap 4 pots too !?

 

Tempting on the brakes! But i've just bought some 296mm Subaru 4 pots!

Intrested in the ECU or intercooler though........

 

Will consider putting it back to standard as it's got a mint carbon fibre bonnet that a few people have asked about

 

ill take the brakes for the right price and replace with subaru 4 pots and mintex high performance pads ( and i dont mean 1144's or 1155's )

 

What pads do you use with the subaru 4 pots ginge?

Was planning on using the godspeed grooved disk with the godspeed kevlar pads?

 

mine are non road legal and aint the best when cold if im honest BUT DO NOT EVER FADE !!!,,,,, need to upgrade the rears though as the ABS gets confused easy

think they are called D2 compound, they are part of them racing pad range,,,,,, oh and they eat brake discs,,,,,,,, and i mean EAT them

 

Cheers mate, ill have a look about.

You still after a box? DCCD any good?

 

NOW someone has a DCCD box,,,,,,,,, how much but i have already got a box,,,,,but if the price and all that pmsl

 

Think he want 500 for it
Its from a type r my mate is breaking.
For that thou, it includes the lot! rear diff,DCCD ecu, dash, box the lot
Might get it myself but not sure on it fitting my 96WRX

 

sounds like maf sensor

 

you take the back of the box off and it will fit, piss easy tbh

 

What prop would i use? would the type r one fit?
Thought it might be shorter with the r being a coupe?

 

Is there anyway of checking it's the maf without buying another??

 

The first thing to do is check the fault codes. The early Impreza's did not give as much problems with the MAF as the 98 to 00 models. There are 2 black and 2 green connectors near the steering column under the dash. Connect these together and put the ignition on. Count the flash codes, long flash 10's, short flash 1's. Let me know what the numbers are, and I will tell you what to do next.

Its just the shell thats different mate, the actual chassis is the same length.

Nice of you to offer John.

Faulty MAF on a 93 will show up fault code 23 and it's done as described as above.
