Btw, I drive a 1.9 Peugeot 205. Not quite the same as the Impreza, but not a bad car at all.
Sorry to have to ask 'for my dad'. I know how juvenille that looks.
Thanks for any replies.

100 bhp..

hmm..

cant remember if you said a year... either way your aiming for circa 350bhp...

I would... (not taking into account what you have allready)

New Fuel Pump (std is ****)
New Injectors 540cc or >
Decent AirFilter
Decent intercooler Either TMIC or FMIC
Decent exhaust + D/Pipe + Up-Pipe + Porting the Headers / Manifold
Possibly Hybrid turbo
Lots of boost...
Custom ecu remap from ecutek or a Link replacement ecu... or a little board from someone else

David
Ps pissed so not much usefull advice..

Put Nos on it

I'd agree with what David says above, a rough idea of costs would be:

New Fuel Pump (std is ****) £150 ish
New Injectors 540cc or > around £500 (though there is a group buy going on somewhere on here for about £350 I think)
Decent AirFilter £50-100 for a filter, £75-200 for an induction kit
Decent intercooler Either TMIC or FMIC TMIC about £500 FMIC upto £1200
Decent exhaust + D/Pipe + Up-Pipe + Porting the Headers / Manifold complete exhaust £500-£1000, porting quite cheap, esp. if you do it yourself
Possibly Hybrid turbo ££££ loads
Lots of boost...
Custom ecu remap from ecutek or a Link replacement ecu... or a little board from someone else £500-£1500 depending how far you go

I've taken my MY94 WRX from 240 to 330 bhp doing most of the above (induction kit, full exhaust, FMIC, Power Engineering ECU Remap, 550 injectors).

100 bhp will not be that cheap. If he wants a bit more power this can be done for a few thousand

Obvious ones are:

Full decat exhaust (may be best to get a high flow Cat for MOT)
Air filter (not Blitz as they have been known to knacker turbo's - I was one of the ones that suffered!)
Link Ecu, 3 port boost solenoid
Or you could opt for a fuel and boost controller like a HKS - very basic devices that dont give the true potential of the car
Octane Booster on every fill up

This lot should be good for about 60bhp

The Fuel pump is fine. Whilst changing mine improved flow there was nothing much wrong with it and it would have probably coped with the additional 100 bhp

As far as injectors go, yes these will max out, but should be 'reasonably' ok for about a 60 bhp rise - they will max out potentially a little above 6000 rpm, but this will be marginal on say 60bhp gains

Turbo's - the standard one is good for a fair bit more power, whilst a restriction, it can cope for a fair increase. If you want a Hybrid they can be modified by Turbo Dynamics but you will suffer from higher lag, there is always a trade off between power and lag on the turbo........

NOS is a very bad idea, the pistons will not last very long and could go immediately (a big gamble - you may be fine - but you may not) anyway NOS does not really do much for your torque (the real power you feel)

steve McCulloch

I should have a little more than 360bhp at the next Well Lane Meet

But hey, I'm just a novice..........

Of course I should have said that the 60bhp would be real gains - whilst I can get 360bhp at Well Lane, this always is an overstatement, compared to others - I would say you can take the Well Lane number and subtract about 20bhp to give a more realistic figures, compared to say PE or PStation

David_Wallis

Sorry dont agree.. Ill try and back that up with some evidence...

Also got a cd with a few test tracks on that I'll bring to well lane if your going.

David

I guess I'm speaking from 'sti' experience - is the UK fuel pump different?

the sti one in my car, would probably be fine to 400bhp, but then why take the risk when the replacements are fairly cheap and take about 10 minutes to change (that is if your boot is not full of stereo gear and amp boards, etc, then add about another 1hr!

Will be good to see your car... 350bhp should be interesting!. Might have similar power to mine then?

David_Wallis

Hopefully... just sourcing some new injectors..

David

Ahl

Thanks for those replies.
He certainly wouldnt use NOS as he wants the constant power and isnt a drag racer!

He'd probably fit most of the bits himself as he's an engineer and was a motor mechanic a long time ago.
Do induction kits really make that much difference on imprezas? He's a skeptical old sod & I dont think he'd want the exhaust/induction noise to be too loud!
Can anyone recommend a few good internet/mail order companies?

You won't get near 100bhp extra on your current turbo without seriously stressing it. If you want to go beyond 300bhp you'll almost certainly need a bigger turbo and a better intercooler wouldn't be a bad idea either.

Ahl

Do you have a scoob yourself Saxo Boy?

LG John

Do ideed, MY99 with scoobysport back-box (soon to be full system) TEC3 with a dawes calling the shots on boost control. I know of similarly set up cars that are good for between 270-80bhp but I'm told its difficult to go much further with the 99/00 TDO4L (hope thats the right name for it) turbo. Quite simply its too small and runs out of puff, my boost drops a fair bit towards the redline but the big turbo boys hold full puff till the limiter.

Trout...

Sti experience - the fuel pump was crap.

Fine on the road or rollers - however anything over about 300bhp on my car on track and EGTs were impossible to control - WHY? Because there was no fuel over 1 bar of boost.

New pump, hey presto car runs tickety-boo on track, and I can have whatever boost and EGT I like.

For others who don't have EGT - they probably would never have noticed, until the turbo/car/piston melted.

Trout

David_Wallis

Was running on 3 Cylinders a cunning ploy to reduce egt's???

steve McCulloch

Wonder why you got no fuel above 1 bar of boost?

Oh techincal wizard, how can you tell through exhaust gas temparatures?

I have not taken mine on the track so I'm not too concerned

Took the Cosworth on track(only for a jolly) but that had an uprated pump as the standard one has to be replaced almost immediately you tinker with the bhp

(Stage one was I think the chip, 3 bar actuator, fuel injectors and fuel pump) but I may be wrong perhaps some of those were for a stage 2.......

The percentage utilisation of the 740cc injectors went from about 75% at max boost to about 66% with the new fuel pump.. which means it does make some difference - but nothing that I was too stressed out about - must have been in sheep mode again (like a couple of years ago with airfilters like Blitz then HKS.. cos the Blitz one destroys turbos)

You can get about an extra 60BHP out of the VF28 - dont know about the UK specced turbos - thought that Rich Wild was running a std turbo - I may be wrong through
In fact I thought that the TDO5 was capable up to 400bhp - were did I read that.......

Ahl

Ok, ok, thanks for all the suggestions, although my puny little mind has problems comprehending all these ideas!

I spoke to him about the Prodrive Powerpack etc, but he'd rather save ££££ and do it himself if possible.

From the above, what (in your opinion) are the cheapest, easiest methods to increase the power? (Possibly by doing the work yourself.)

Thanks again.

LG John

Dawes Device (£35) and a boost gauge will allow you to crank the boost up to about 1.15bar (well actually much more but fuel cut will have a say) nice and safely (standard car = 0.8bar IIRC). This alone will make the car feel a lot faster and will slightly improve the actual performance. If you then get a full exhaust system (about £6-700) it'll be faster still and much lounder However, to go above 1.21 bar of boost you'll need some method of getting rid of the standard ECU fuel cut - there are a number of ways to do this.

LG John

I used to have a VTS and posted on here for a while before getting the scooby. People know me this way so the name stays

Pug 205 driver eh, tisk! I remember I raced a 205 1.9 GTI at crail and really looked forward to what I believe would be a dead heat. I asked the guy if it was standard like mine and he said, 'oh yeah' He then flew past with big loud zorts rasping away ......git!

Jamie a JW racing sells the dawes device if I remember correctly.

Thanks very much.

My 1.9 205 is standard at the moment, but it wont be long before it has an mi16 or a good tuning! In fact, an mi16 205 has more power to weight than a standard scooby turbo! (Loses out on the torque though!)

Anyway, I look forward to ****ting myself even more, after my dad has fitted all these bits to his car!

Ahl

Hi, im absolutely brand new to this forum...but ive got a good question to ask.

My dad has a 1999 Impreza turbo which is standard apart from Prodrive suspension, wheels & gearshift. He'd like to add another 100bhp to it, but would like to know the easiest, cheapest & most reliable ways of doing this! Ive already suggested boost controllers, a decent chip, decat pipes, big exhausts, but I dont have any experience of these cars at all to be honest!

What would you suggest?

[Edited by Ahl - 9/10/2002 12:05:06 AM]

HELLOM8

Adding 100 bhp will cost if done right with new bits and could hurt the cars reliability.
It might be an idea to go for the Prodrive Performance pack or a power pack powerengineering or just a Tek 2 ECU and other bits for around 250ish BHP.




[Edited by HELLOM8 - 9/10/2002 9:05:05 AM]

Ahl

Thanks mate...where would be a good place to procure such a device?
I dont know which subaru parts dealers to trust you see!

And just curious, but why is your name Saxo boy? As a peugeot 205 driver, saxo's are almost my natural enemy!
