just thought i'd share this with you guys... totally gutted!!
car has been mechanically faultless for the past 3 years.. and then suddenly a piston goes...
was on the way back from the wales motor show - after winnng a trophy for the sound off... cossie comes up behind me flashing his lights..
so i did the decent thing by droppping down a few cogs... i should have thought twice - as afterwards i found out this guy is running about 500bhp.
anyway got home and the car wasn't feeling right...
i has a feeling something big was wrong - but was in denial...
anyway did the compression test and hey presto and there is a piston gone!
plus side is - there is no plus side really!!
should have car back this week - also chucking in a exedy paddle clutch and flywheel - ported inlet manifold, motul oil and pitwork oil filter.

anyone had similar problems??

Was it your WR1?

Was it your third piston which went by any chance?, my last engine had scoring on the piston liner on third piston due to running lean when running high boost pressure resulting in temperature increase Usual fault with differential fuel pressure from first to last piston across the fuel rail due to having a partial blockage within fuel filter. Eventually the water pump failed which actually was the final straw and the engine packed in.

Guess it should have been mapped for uk fuel

osaka

not sure which piston it was.. have not seen it yet.. should be ready tomorrow or monday.
the car is a 93 wrx import... just one of those things... i was not running excessive boost.
whats done is done.... just gonna have to take it easy for a while now - run it in... new clutch on it as well.
just miss the sound of it...

the wr1 just came out of the workshop yesterday with a few toys on it
gfb pulleys
gfb shortshifter - very short indeed
blitz boost controller sbc1 colour
whiteline suspension uprated bits such as anti lift kit, diff support etc etc etc
basically everything whiteline do for the car..
now it feels like your in an f1 car - it's so stiff and handle so well.

I had the same happen to me except I lost all power due to ahole the size of a twenty pence piece. It was caused by a dodgy Maf sensor, Just had a very slight misfire @3K, I

f I was was you I would swap the MAF, and put a knocklink on while you are there!!!

Another blown motor

Yes, twice

osaka

i done the maf sensor - will do the knock link for sure. just never got round to it before.

How much did the MAF sensor cost u for the 93 wrx? Might need 1 for mine as its started missing a bit. Gonna change the plugs first and see how i get on. Would CVC supply it?, had probs with them in the past due to it being an "Import"....run away, run away!

osaka

your better off getting a maf of grade a subaru - cheaper...
my car is still in limp mode after resetting ecu - need to get the codes. i think the knock sensor may need replacing!!

Russ71

I'll take your word for it, it's all very confusing to me, just to let you know those bulbs work great, cheers mate I'll be a regular customer now, no more Halfrauds for me I hope your car feels better soon.

I'm starting to hear of Subaru owners swapping their standard Subaru mafs for Nissan 300ZX items. As supposedly stronger and good for air flows for cars running over 400 BHP. I found a 300zx maf on the Nissian forum for sale at 80 pounds and wiring instructions have been post under general on scoobynet. I'm looking possibly of convering myself but waiting for a someone to try it out first!, so Taylor tell me how you get on.

tay05

Cheers Jon. I'm hoping the problem is just gonna be the plugs, just bought a set of NGK PFR 7B's to replace the old 6B's and gapped them down to 0.5, these will be going in on the wk end, hopefully this will clear the misfire. From what i've heard the early MAF's are supposed to be bullet proof so if it isn't the plugs i'm guessing the coil packs.

I know Bev (jamesWRXRA) is having the same problem at the moment and finding the route cause a bit of a frustration. He is also suffering from boost spiking which only happens now and again in 5th gear.

I've had both problem overs the years.

Failing maf, will make it run lumpy and be all over the place whilst idiling, blown Maf will force limp mode.

Also had a misfire a couple of years ago turned out to be a cracked spark plug,

jamesbWRXRA

Frustrating! Tell me about it . I can't wait for the car to be fixed and back to running like the car i originally bought. Finally found the water leak its a watercooler pipe which runs under the turbo. Quoted 69.99 plus vat for a new pipe! Someone will be having a go at welding it me thinks. Hopefully getting it repaired next weekend. After that its up to Ace motorsport i think to find out why the car is running like a dog.

Tay does ur car feel like it judders slightly when u come off the accelerator. Also car kangaroos like hell in the morning sometimes when cold. My car is also hitting 1.1bar with the standard ecu and it should be o.7bar. Which is resulting in either fuel cut or a boost spike . Either of which is very scary when it happens on overtake. Also feels hesitant and jerky around town.

As you can tell not having much fun with the car at the mo . Need to sort out all the running problems so that i can get back on the rollercoaster and catch Jon up lol. When all this is sorted i'll be in touch if u don't mind tay for some advice abouting fitting a front mount as i think this will be my next project if i ever get this car to run properly.

James

Hey James, nice to hear from you, if u ever want any advice about the front mount don't be afraid to ask. Having some probs myself at the mo, although nothing major still bloody annoying....clutch is about to be changed as its startin to slip under high power, tho just through the age of it, this is on my floor waiting to go in with a lightened flywheel fom API. The miss is not too bad, either caused by tired coil packs or plugs, either way Andy F says gappin the plugs to .5 should solve this...no probs idleing so guessing its not the MAF, other than that the car is running like a dream.
Taylor.

jamesbWRXRA

Hi Tay . Nice one mate . It probably won't be 4 a while but could certainly do with some advice as the job on your car looks good. The same usual suspects on my car . Could be maf. Could be coil packs. I think my spark plugs are also gapped incorrectly so hopefully i can get them changed next weekend. When this is sorted i need to get somebody to run a diagnostics to find the problem.
