just noticed that when trying to go on boost it whistles. and nothing happens. and after i release the gas pedal i can hear popping noise i think it cames from exhaust pipe. the boost gauge show 1 bar of boost but it feels like something is holding the car... maybe need a new fuel pump? anyone got any ideas of what can be wrong?

Have you got a BOV fitted ?
If so, it is probably leaking.
It will also cause overfueling when it blows off and that will make the excess petrol burn in the exhaust causing a popping noise on the overrun.
Could be the mother of all boost leaks? pressure test the pipework from compressor housing exit to throttle body and trigger bottle spray soapy water over the joints and pipe work and can test bov/dump valve at same time if got 1,
more spec on the car could help,as in stock ecu and fuel pump? (need a walbro 255 even if stock spec car imo) still on wing mount cooler? etc,wmic rot and crack and leak like crazy, the whistle could well be the boost leaking from somewhere?
No bov at all. But it sounds likebit has got one when changing the gear or lifting foot of the throttle. Well as far as i know the fuel pump is stock. It has got big ass intercooler in the feont if the car and aftermarket induction. And i think thars it when it comes to moods.
pretty much stg 1 mods with no fuelpump i think you need to check for boost leaks and then get a walbro fuelpump without a doubt. Running lean at 1bar boost isnt good!
it wont run long either before melting pistons.
Check your cas is not dodgy and set on 15° too.
we set the timing at 15 and it was a little over to the left so checked cambelt and thats all correct!
Well i need to change the actuator now to less boost. What can i set it at? And also now the car iddles funny as well. Goes up and down and uo and down. And the car runs funny as well. Like it gets more booat for few secends and it stoops.
sounds like boost leak! You can adjust the actuator for less boost, should only be running .6-.7 with out the upgrade fuelpump and some colder plugs NGK BCPR7ES are what you want.
Well its pain in the ass to adjust it ehh.
shouldnt be to difficult mate! just have to fiddle with it bit of trial and error!
Twang the 'c' clip of wastegate arm (don't loose the clip) and hold shaft with mole grips at the end of the thread if needed,lock nut undone should move easy if not on the wastegate lever,bit fiddly but do-ableOriginally Posted by blackss13
Ehh. Im about to give up on it m8.had enough of this s13.
think most of us have had moments like that lol
Yeah that was me 5 yrs ago,my 1st job was pull the cylinder head off and replace inlet valves to get the compression back,Its worth the agro tho,when they work ok they are nice cars,leave it for a bit if causing you grief mate?,don't sound that bad to fix just need bit of time to go through it checking stuff
well i need to see what wrong with it then decide if i want to continue to work on it or just give up and go back to my em1...
Found that boost leak today...got it fixed temporary as im off to amsterdam in the morning so the only thing to do as i come back is to get few hose clips from halfords and put them on as 2 of the ones i got are broken. Walbro fuel pump and new spark plugs will be instaled so hope that it all will be running good.
Sounds like a good plan,glad you stuck with it,with the boost leaks fixed and the other bits fitted it will be a different car to drive
Well yeah. Hope it will be worth it. But it sucks that im away till 2nd without my s13. But will enjoy it when back home
Mine made a slight whistle when my turbo gasket was gone,
Check the bolts are right aswell, mine where proper loose.
