Hi

Do I need to remove the restrictor pill when fitting a manual boost controller

rb5 stu

No.

mbright81

That's a nice simple answer. I thought mbc took over from the restrictor. Thank you

mbright81

I genuinely thought after all the research I've done today I was asking a question I knew the answer to.

restrictor pill? ive bypassed my solenoid because it mullered and lets my scooby boost to abour 1.6 bar which then hits fuel cut in 3rd 4th and 5th.

Have u just run a pipe from turbo to wastegate?

XDevil666

Manual boost controller?

Ok I'm just sitting here waiting for you to post the engine rebuild thread

Don't be a div, don't install those cheap nasty things, do it right and get your car mapped

You bodge your boost your fueling is going to be way out

XDevil666

Lol, and your still running that? Ok gonna be 2 engine rebuild threads soon

***** sake if you guys can't afford simple mods and tunes why buy the cars in the first place!!

mbright81

Thanks for your response. I've been looking into this all day and I posted a thread earlier that had some useful responses.

Basically I bought my 97 with a decat midpipe and I've had to replaced the headers and up pipe because they were leaking badly.

After doing this Ive been overboosting in the higher gears.

I know that a remap is the perfect solution but on these models they can't be remapped unless you spend ££££s

I'm interested in a mbc only to control the overboost situation. Not to be silly with it.

I'm convinced the restrictor pill should be removed but can't find a definitive answer

the older cars are so cheap new owners with a fiver spare buy them and chuck all sorts of unmapped crap on them blow them to bits and fill facebook pages about how unreliable "scooby's" are.
when the real reason the explode is due to the new owners lack of finances and knowledge to tune them correctly.

What you are trying to do is cut corners and bodge your mods on

In affect what your doing is blue tacking something which should be screwed on

The restrictor pill shouldnt be removed

But anyway you carry on the way your going and enjoy the short life span of your block

XDevil666

There are some fruit loops on those Facebook groups!!

Really is embarrassing reading most of the posts

mbright81

How can my block be at risk if I keep the boost level standard?

If it stops my overboost surely it's not a bad solution

I'm grateful for your response. Please don't get me wrong

XDevil666

You just changed your manifold, put decatted exhaust on, obviously your boost lines aren't right as your hitting your boost cut offs

Manual boost controllers are aweful at holding a controlled boost also

And how do you know what the manual boost controller should be set at?

Right now all your fuelling will be out, ask any mapper on here they will tell you the same

Don't follow Facebook groups or anyone modding on tight budgets, you will be advised very wrong

I can see your logic with what you're suggesting. Main reason being even tho you're trying to regulate the boost the ecu can't see what's happening. Yes it may be boosting correctly but if something else gives out or goes to pot the ecu can't determine the boost and restrict it for a better word if it needed to, so your "correct" boost may not be correct in that instance.

mbright81

I don't believe in facebook so don't worry about that.

I have a boost gauge so I can see what I'd be setting it at.

I see where your coming from about the fueling. I was just looking for a fix that didn't mean buying an ecu.

Thanks for your help

mbright81

You have the same ring as devil666. There's no cure for overboost without remap.

Thanks for your response.

no doubt hundreds of half arsed bodges available and one correct cure.
the thing is you have a performance car so why compromise its performance and reliability by doing something stupid??

mbright81

I hear you. Money talks and bull**** blows up on the way to tesco.
I love this car. F**kin expensive though

i got a esl'd ecu for 220 , need the board taking out and installing in my ecu then remapping from there 300 so 520 + tank feul so well say 600 once ive bought lunch, got a garage of mods ive collected up over time, its not like youve got to spend 1000s in one lump, get the car running standard spec get a second hand cat for what ? 50£?give it a service, get it running healthy and just run it like that until youve all the bits and get it mapped it will transform the car

Essex

Probably should have mentioned this so all the keyboard warriors didn't jump out of their prams, I have a piggy back system which is currently being mapped to compensate for all mods including raised boost and a couple bits to be added later in the week

id get back in your pram, some of us have seen newbs like yourself come and go and blow up old imprezas and dream of building drift cars and other such fast and furious crap

ever thought some of the comments are from experience??

That sounds like s good plan. When pay day comes round I'm planning to change oil, filters, and plugs. I've got a cat and the donut gasket but I need to get a different back box cos its a 3 inch.

One step at a time I suppose

i think esl new installed and mapped from a dealer/mapper is 575, iwas planning on self mapping but cant fully understand it so leaving it for a pro , thats why i bought a second hand esl'd ecu

Essex

if you say mate, newb? think not, been working on cars for the best part of 10 years, some built by myself include a 600bhp mr2, 700bhp evo 7 just to name 2, so before you slate, get your facts right.

plus judging by your comment you didnt read my post completely and missed the part about having a piggy back set up with mapping to compensate

Essex

i couldnt agree more, if your unsure let a professional do it. heard good things about the esl but never used one myself

i can imagine you have built many amazing motors and thats why you trundle around in a 1997 wrx

It's pretty much all already been said. Unmapped mods will gain little and ruin performance often ending in tears.

However if its just to get you by until you map (this should be sooner rather then later) you need to drive your car like miss daisy. I.e. slowly accelerating using a small amount of throttle not going above 3000rpm. You are then keeping your car from boosting and hopefully won't ruin it. You can however for example have a load of boost at 2500rpm if you are in a high gear and load is great ie trying to accelerate up hill in fifth at say 40mph. Not something you should do anyway but just an example of how you can end up with potentially damaging boost even driving carefully.

You can just plum turbo nipple straight to wastegate actuator. Then you will have about .5bar boost limited by the spring pressure. That is another half measure of safety but you really need a map...

Essex

na im not running it lol i put a boost controller in after the solenoid and turned it down so rather than the 1.6 bar it would let it run its only pushing 0.9

Essex

i happen to like the classic which is why i have one lol if i wanted a newer impreza i would have one lol
