Wrx sti ra boost cutting out/power loss
 

Hi, my 95 wrx sti ra v2 keeps loosing boost and cutting out when you floor it. Have not had it that long, so do not know much about them, but has a boost guage usually boosts just over 1.0 bar (is this toomuch, is suposed to be standard) but dropps down to 0.5 and it jerks about a bit. Has done it the last 2 times i have driven it, the last time the engine cut out for a second too. Can anybody help, have i got a bad car or is it something stupid ive overlooked?

Thanks

James

have exactly the same problem with my type r , started happening as soon as i fitter a blitz sus induction kit (think its now over boosting) so ive ordered an apexi pfc ecu and will be getting a remap soon to hopefully sort it out....

My car is supposed to be standard, it has got a standard air box. Do you know what the standard boost is or how to tell it has been chipped? Or is there another reason it will be overboosting, it does feel like the ecu goes limp home though afterr the boost goes up.

not too sure what std boost is and still having problems with mine, if i find any thing ill let u know, also try checking ur boost pipes and and clips as they sometimes come loose which lead to sudden loss of boost under load....

let me know if u get it sorted m8..
good luck

Thanks mate, will do! Might have a trip to the local rolling road to see what they think!

i had exactly the same [problem with my v2 ra and it was the map sensor if you speak to scooby clinic they sell new age ones converted to fit classics i did this and never had a problem since

Thank you ginge2719! At last some actual practical advice, and a recommendation for an actual scoobie specialist nearish to my house!

Anyway, have changed the map sensor and solenoid from one out of big bin of marked solenoids (ebay advert says unused from japan direct parts), now it holds boost most of the time but still does the same fault! Think I've prob bought another shagged map sensor! I will be straight off to mansfield tomorrow morning! Plus its an awsome drive from manchester (glossop-->A624-->A623)!

Seriously, thanks ginge!!!

Have been to scoobie clinic, is amazing! Guys were really nice, watched an RB5 do a power run on the rollers and saw some amazing cars, inc 3 22B's! Have dropped my car off for them to sort it out, and get an alarm/turbo timer, service, an oil cooler and a remap to 99 Vpower. Cant wait to get it back!
