but could you tell me what is the point of having the the restrictor pill fitted on the bottom pipe for the resinator

 

The restrictor works kind of like a 'bleed', the air bled from the BCS has to bleed at a certain rate so it acts on the BCS. ie if no restitor fitted the air just 'falls' down the pipe and the BCS feels no back pressure, if restrictor fitted air pressure backs up to the BCS before being 'forced' thru the restrictor which then allows the BCS to operate as Subaru intended. Where the air goes after it is bled is not really a concern, either back into the system or to atmosphere

 

b13bat you are a little fountain of knowlage every subaru owner should have a b13bat cheers pal

 

iv got the ristrictor pill out of one of the pipes i borrowed but it apears to be to small for the bottom pipe of the boost solinoid

 

would it make any diffrence if i put a smaller pipe on the bottom pipe so i can get the restrictor pill in

 

bttt

 

also the car does not seem to spool up till later on about 3 and a half

 

bttt

 

Thankyou for that, you are welcome to any help i can give Iam


No, it should not make a difference as long as the pill is in place Now i'm not 100% sure on this but, i think not having the pill fitted will effect the spool time Someone will pick me up if that is not the case

 

i put the pill in but it has made no diffrence iv changed some of the pipes but still again stiil no difrence

 

This sounds like you are running wastegate boost pressure. When this happened on my bugeye it was the boost solenoid that was knackered. See if you can find someone who can loan oyu one to test it, they can be had cheap enough second-hand. Also, the spring on your wastegate could be worn and not holding the boost. This is apparently a common problem on classics, so a new wastegate might be the order of the day.

 

cheers for the imput but i have changed the boost solinoid from scoobysmiffs car and i fitted a difrent turbo the other night so that should rule out the wastegate ,steven

 

Right, i have just re-rear the thread, and in post #1 you say

Also in post #1 you say

Which thinking about it (bear in mind that it's 05.30 and ive just got in from work ) tells me that the problem could lay with the install of the engine
You've had 2 different BCS's and 2 different turbos on, with i assume 2 different wastegates and actuators, so the BCS, turbo and wastegate assy have been petty much ruled out
So as

and all the suggestions in this thread have failed to resolve it, it may be time to check you wired and plumbed everything correctly after the engine change, or take to a specilist and have it checked

 

that might be a good idea ill get on it today or tommorow

 

still no hope for me

 

There's always hope, i hope, otherways i'm ****'d As mentioned in post #20, you could disconnect the pipe from the wastegate and go for a 'very' controlled drive just to make sure the turbo is boosting
Disconnect the pipe from the wastegate actuator and see if it boosts up, but be very very carefull, no foot to the floor, just watch the boost gauge and dont go over 1 bar, this will eliminate the turbo being at fault

 

i was speaking with harvy smith and he said in the early jap imports wrx with 3 port boost solinoids i would not have a restrictor b13bat

 

i witl try that today b13bat and ill let you no how i get on

 

Mate,

I had the very same problem with my old 93 wrx. Every week for about 30mins it would only boost to 0.5bar, then somehow it would boost back to 0.8bar of its own accord???

I changed the ecu, boost solonoid (with pipes), turbo, all the pressure sensors, afm, O2 sensor.......and basically everything associated with boost control.

Still did it until I fitted a Polar performance ecu chip (takes boost from 0.8 to 1.1bar and adjusts the fuelling)

After fitting the chip it never did it again and ran perfectly for 12mths then I sold it and the new owner has had no probs either.

Go onto the General technical page, in the search field type in '0.5bar boost...' should come up with my thread

 

cheers buddy im going to get it remapped once i get a fmic and some 440"s so who nows maby that will sort me out

 

right iv taken the actuator hose off like people have said but still no diffrence just made my dv sound louder??????

 

No more than 0.5 bar boost with the actuator pipe disconnected

Dont really know where to go from there mate, sorry

 

thats me just going to nip down the garage and get 5 litters a petrol and a box of matches now lol still cant pin it down to anything to many sleepless nights thought i would have got boost without actuator conected

 

yepeeee finally got just under one bar of boost, went through ecu reset again may i ad and was running better just a quick question tho once you reset your ecu does the car take tim to remember its setting cause at the start it wasnt getting 0.9 bar untill just after 6k revs but as i drove the car longer i started getting about a bar at 5 1/2 anybody

 

Well thank **** for that Your Ecu does learn but only as far as advancing/retarding ignition.
Pleased you have it sorted

 

b13bat you are a star and thanks for sticking with me do you mind if i stick you on my friends list

 

Not at all squire, you're welcome

 

glad it's working mate, just tried ringing..

 

hey sorry for bringing this up again but its a recent thread

i replied on page 1 - i had this problem all of a sudden but it sorted itself out a day or two later

after a few weeks of normal operation its back to 0.5 bar



im not sure how to reset ecu can anyone point me in right direction ? and it wont **** anything up will it doing this ?

im also gonna plug the black n green plugs under dash first to read any faults there maybe

thanks

 

its ok i have consulted the almighty Scoobypedia over on SIDC

see im not lazy
