restrictor pill

hi just a quick question if this isnt fitted what could occur just carnt find one in the pipe from the solenoied to the wastegate actuater and mine is not boosting as it should ie very laggy

depends wat year car urs is, if early classic it will have a 3 port solenoid so no restrictor needed, wat boost you getting, you may have it piped up wrong to solenoid

Andy

alright mate it boost is 0.9 just not boosting till 4000rpm mate only found out that this was case when rolling roaded last week mate

it is an early classic with 3 port clean it all out and blown the lines out from the solenoied mate

i am on back shift next week were are you located mate cos might just like your opinion on this mate

cos my next thing is scrap the front mount which was already on it when i bought car it only got 194bhp on the day

The restrictor pill is in the outlet pipe( bottom one) on the standard 3 port solenoid setup, it keeps the boost down as apposed to keeping it high on the 2 port.

around 0.9 bar boost sounds about right for a z4 ecu that you have fitted.

194 bhp is very low, should be around 260-270 with the mods you have.

2.0 + TD05 + front mount is a receipe for lag to be honest mate, a front mount in my opinion only becomes beneficial over 360bhp.

that may be the case johnny mate that was me next thing to take off and but tmic back on cheers for all the help and finn for tuesday night over the garage and johnny mine has a 7d ecu hope this doesnt make the difference

7d is a uk ecu not an import, is yours a uk car?

yep it is mate thought that was there difference but had slight doubt there

honestly never seen one in the outlet pipe as this is 5mm bore, ive fitted loads of early classic engines back in and usually renew the pipes and they boost fine

theres ya problem regarding lag, a tdo4 is gunna struggle like mad with a front mount, bit lyk trying to inflate a bouncy castle with a hand pump, ie get neewere fast

i read on scooby pedia i think that the 3 ports have one in the pipe ging to wastegate actuator as i say i no very little but willing to listen and learn you both been in impreza for along time like i say could just be intercooler hope so

i think its td05 mate

a uk classic has tdo4, also the ecu youve just mentioned is to run a tdo4 and rated at around 214bhp

ok thanks mate this is a bitsa car mate as i bought it and havent done any thing myself if i have td05 what ecu would manage that better would that be the z4 mate cos if it is might buy one for the time being before i get either simteck or apexi early next year

a doubt it has a tdo5 on as engine wont last long running a 05 with an ecu mapped for a tdo4, i cant really advise wats best for you to do until you know what turbo it is fella

Andy

how do i tell mate is there an easy way cheers for taking your time to help

cheers mate thanks for your help and if i need to were are you located mate

Howa Andy, are you having an off day?

It's a pre 96 uk classic, it has a td05 as standard, and the restrictor is in the pipe that goes from the bottom of the 3 port solenoid to the plastic resonator box (that the nipple always snaps off).

To be honest I have only seen the restrictor in the WRX's, never had a uk pre 96 classic to bits.

lol, yes it will have a tdo5 was thinkin summit else, jonny hes on about a pill in the pipe from solenoid to actuator, defo nee pill in there but sumtimes the bottom pipe has one in

like a told you on tuesday, FMIC are shite..

yes over 400+bhp where u need too get the intake temps down.. are wen FMIC is good (still not what i personally would have)

jonesy a will have a TMIC which will fit your car.

it will feel a totally different car with TMIC on, believe me

finn how much for a top mount then mate i think i will have to eliminate this issue and hope it works bud i am starting to understand why u think this so yes gives a price and will have one i thinks cheers everyone for your help.
