You could just fit a fuel pressure regulator, fuel pump and up the boost but this method will sap power as it hideously over fuels.  This is the cheapo method of doing it but it very hit and miss type of tuning technique if you dont have the appropriate tools and monitoring equipment to do the job.  People who do this are only after kudos for parts fitted , oooohhh its got a reg, pump and flamer kit so it must be over 300, when it hits the rollers a rather dissappointing figure is achieved

AndyAdonis, your car comes with a TD05 16g turbo as std the UK 2000 comes with a TD04, i can fart more air than a TD04 can flow.   Dinna ask me i know absoloutly hee haw about these things.

Nos puts a strain on a std clutch due to the sudden impact loadings of the NOS activating.   Installed wrongly it turns your combustion chamber into an oxy-acetelyne gas torch and melt those std pistons pretty quickly.

Best advice BigDavie would be talk to someone who has got 300 before on a similer car and take it from there.

AND DONT CUT CORNERS as it will come back to bite your bum later in a big way

The chav way is to fit a flamer kit, graphics and a huge wing on the back and make it look as if it has 300hp....IMHO

The proper way is to understand the fuelling needs, the cooling needs and its breathing needs.  Spend the proper money and get the proper parts fitted and then take it too GOD for him to write a nice safe program for all the new bits to sing in harmony

REMEMBER THIS GRUNTER!! YADA YADA YADA

you really do need to get over people having more than you and get shot of that big CHIP on your shoulder!!!!

Have a nice day!!

that's a bit harsh ricey. 

No wonder why folk are scared of posting on the forum.

someone asks a legit question, gets 2 answers, discussion develops

quite amicably and you jump in with a comment like that and no one

contributes to the thread for 9 hours, tho i suspect there have been

several views since you posted that sarcy comment. 

It seems like you are the making it personal and that you are the one with the chip on your shoulder.

yes, nos will give you more bhp.

a bigger turbo will also give you more bhp.

both answers are correct.

can't you accept that there are different views.....

can't you just let this grudge against the squirrel go??

the whole damn community knows that you both have vastly different opinions on anything / everything relating to scoobies [:@]

imy

ps - sorry bigdavie for hijacking your thread [:o] back to more bhp....... more power [:D]

imy sorry to say its grant that starts all the time.

he has always got to bring people into it what ever the post is about.

But some people just choose to ignore what he say's because this is something thats should not be on the fourms.

i sorry davie [:D]

yeah im gonna do that claire but need to watch the pennies as since ive got this car all ive done is throw money at it lmao !! been lookin at a turbo and think i'm gonna get it !! not told the mrs yet tho !!

Glad to hear it Davie sorry didnt get a chance to meet u on sat with wullie but my hangover took its toll How is the turbo timer?

Claire

Ps Said hello to your car at some point when i was out last friday night LOL

Squirrels way seems to work. A fuel pump and reg wont increase power on its own but make it easier to up power safely reducing the chance of running lean. A tdo5 is prob a good bet with a remap. A sti5 or 6 top mount is good enough for up to 350 and cheaper , easier to fit than a front mount. If 300 is your limit pump, reg, tdo5, sti 5/6 top mount and a remap should give you a safe and reliable 300. This can be fitted a bit at a time when funds allow. If your planning more at a later stage then fitting a front mount is prob a good idea.

ahhh the demon drink lmao im just about to get stuck into some md 20/20 the now !!!!

the turbo timer is fantastic the look on a guys face as i stopped at the garage and went in with the engine still running was great !!

and i think my car (suzie)said hello back btw lol !!

I am quite happy for Ricey to call my car a sh*thole, me a grunter thats a waste of space with a chip on my shoulder and i do not reply to his direct insults on the forum.  I kept my reply to his direct insults by PM and being the waste of space with a chip on my shoulder, i thought this would be the best way to communicate to keep the grievence off the public forum but i have never recieved a PM in return (unless you count publishing all my PM's on the forum and telling the boss that the bad Squirrel is sending me nasty PM's)

May be a waste of space with a chip on my shoulder that drives a sh*thole but i have given Davie advice that will see him to his requested goal with a healthy degree of reliability.  I will stand by that advice as it has seen me and a few others ok with thier pursuit for power.

If i want advice on graphics for my car then i know where to go!

If i want advice on interior trim and how not to do it, i know where to go!.

If i want to hideously overfuel my car to the point of losing power i know where to go!

After Davie fits the pump, regulator and intercooler to his car, what pressure do you reckon he should set the regulator to, what Air to Fuel Ratio should be aimed for and what would you use to measure this AFR?

This is not a Stalinist regime where my opinion will be dictated to me like some sort of military dictatorship

I think chav cars with graphics, flamer kits, neons and humungous alloys are the best thing ever

"Heard that about AVA too which can upto double your power in one run."

Excellent! Not too far away from me, so i'd be pretty chuffed at having the first proven 1000bhp Impreza! [:D][;)]

Back on topic.....

Plenty ways to swing a cat to get 300bhp.

I wouldn't bother with a fuel pressure regulator at that level. One of the reasons for changing the regulator is to accomodate for injectors which are too small.

With the '99 cars having 440cc injectors, these can cope with 300 bhp even with the std regulator. Same with the fuel pump. It should be fine at that level providing both items are in good condition and not tired.

Don't get me wrong, changing the fuel pump and regulator is a good thing cause you're future proofing your mods and also providing more headroom or leeway should the std parts turn out to be marginal in their limits but not strictly necessary imo.

I ran 300 bhp back somewhere around early 2000 and it wasn't common then to have aftermarket pumps and regulators as you see banded about now.

I think, in bigdavies case though, he won't stop at 300.... [:D] the bug bites you, so as an insurance policy if you like, it might be better to buy these two components.

As for turbo, you can pick up a VF23 for peanuts compared to the TD05, though the TD05 is the better bet because it can be rebuilt cheaply enough and also modified for future power upgrades whereas the VF series are limited in these respects.

Intercooler? Again for that level i wouldn't bother with a front mount. I only say that cause the thread starter mentions he's on a budget. The std top mount intercooler has its' limitations, mainly heatsoak and so most people want something different to get rid of that, but does it matter in the real world?

Yes, you'll get heatsoak by driving in traffic and the temps will build up under bonnet but out on the open road with plenty cooling air feeding into the scoop, heatsoak isn't an issue.

The last quote sounds very true to me.

UPDATE !!!!!!!!!!!!

right i now have a walbro 255 lph fuel pump on its way !!

and have also secured a new tmic that should be up to the job !!: )

now where do i get an fpr ?? will an fse valve thingy do ??

Posted

and also to you dougster the greatest respect back

but as i have said to you before mate i prefer askin and gettin real answers from real people !!

How far do you intend to tune your car?

If you've got an oldish Impreza which has done a few miles, it might have been a good thing to buy a new pump and an uprated one at that cause they're cheap to buy, but imo for 300bhp, your tmic may be better than your std one (again depends on what year of car), but you'll still suffer from heatsoak when in traffic.

Fuel pressure reg? Still don't think you'll need it if you have 440's. Worthwhile if you've got 380's in though ( <MY99 ).

Not trying to put you off, far from it, you spend what you like on your car. I just reckon that for 300bhp (depending what model) it's not really necessary to buy some the stuff that's seen as a common "must have" first purchase when tuning the car. Future proofing, yes... but if that's all where you want to be (300bhpand no more)then if i were doing it all again, i wouldn't bother.

 

Despite my opinion, to answer your question on fpr, some people have problems with the FSE. I had one and never had any real issues with it.

The only thing i would say about putting your new pump and future regulator in, is that you will need to budget for your car to be re-mapped as the fuelling will be different if it's not set up correctly. One thing you don't want is too rich a mixture in any area of the rev band (vacuum and on boost) as this will lead to bore wash which thins your oil out and accelerates wear on your engine. Conversely, too lean a mixture will cause rough running, higher temps and the definite risk of detonation.

If you don't want to re-map the car, then you'll have to make sure you run enough boost to get your mixture right i.e. not too rich and also enough octane in the fuel, so that you don't suffer from detonation. To do this you'll need a good AFR meter to check on fuelling and some form of det monitoring like a set of DIY det cans to listen for detonation. (Easy and cheap to do)

The FSE regulator to get if that's what your buying is a 1:1 regulator, not the 1.7:1 rising rate regulator.
