I have a standard(ish) 2001 WRX (newage) fitted with PPP, so should be around 265 at the mo.

I am looking for a way of increasing the bhp and wondered if a remap would be the way to go or would I need to look at getting a bigger turbo and uprating a few bits engine wise.

Any help and advice will be greatly appreciated

Thanks in advance

Dave

With the right Exhaust / intake, a remap is all you need to take you up to the 300 bhp

thats not what zen told me, think the turbo is good for around the 300 mark at a push but dont think it will last long

SSCJAY

I know of a my00 impreza running 295 bhp for the last 2 years with a TD04 (standard turbo) Prodrive exhaust & panel filter. Not saying Zen don't know their stuff but best to get a few opinions before knowing what can and can't be done.

ZEN Performance

It won't make 295hp on the rolling road I use!

Each to their own.

scooby51

Zen... what do you suggest??????

dogpole

a standard td04 will not make 295...... unless you've been to well lane!!

280 ish at a push with high temps

these are going to be my mods wrx04. new injectors, new sti topmount, new turbo not sure which to go for, new panel filter and 3" exhaust with prodrive sportscat downpipe , uprated fuel pump and remap. hoping that should do the trick

Sounds like a plan. Maybe a VF35 might suit your needs.

ZEN Performance

decat or sports cat exhaust, fuel pump, sti pink injectors (used) VF35 turbo (from newage uk sti) turbo (used), remap and optionally a good panel filter.

315hp easily with great spoolup and long term reliability.

I think with bhp figures you have to be very carefully that you don’t look for figures many companies show big figures on there rolling roads but thats not always a fair and equal playing field, lesson I learnt when shopping around was to talk to these companies and you will soon figure out the BS merchants from the knowledgeable ones,

and I ended up going with Zen, and I have never been on a rolling road so don’t know what BHP its pushing out but it drives so much better and uses less fuel with no reliability issues ( so far ) no need to check its speed I no its fast and so does the m3 I played with in MK today

james-wrx

Nice...........I am in similar situation have no idea of Hp but I do know how to devestate the new Audi TT !!!!!!! Along with every other car in MK!
Who gives a monkeys what the HP is it's the seat of tha pants that counts
My classic has a 2.2 L stroked engine (all forged) hybrid IHI turbo produces a bar of boost at 3k revs (max 1.2 bar) and I havent been overtaken since I have owned it, it does have a P1 box so 0-100mph is quick!
My mate owns "fearnsport" in Silverstone and he had it built, his words to me were that is a F******G quick car and he spends all day everyday playing with GT3 Rs Porsches and GT2 race cars !
His own car is a GT2 running 620 Hp and he still says the Scooby is rude !

robertdon777

As Zen says, turbo (second hand) IHI VF series (28,34 35 etc.) or TD05 FE with a panel filter/ fuel pump and map will all make 310bhp with good earlyish spool.

SSCJAY

I did see the dyno run, was at PE, uxbridge, was about 18 months ago, at the time my 04sti made 358 bhp on their dyno with stock turbo/ injectors with APS FMIC.

No BS here i'm Afraid

?????? WRX not a STI

ClintUK

i know you have newer car than me, but I thnk TD04 is almost the same spec on both and I heard a genuine 270bhp was all this is good for - it simply can not move the exhaust fast enough for more.

So I'm pretty sure you'll have to change your turbo for that, there are a few options depending how far you want to go and what characteristics of torque / power deliver you want.

Read my saga on TD04 hybrid

https://www.scoobynet.com/general-te...bs-305bhp.html

But over 270bhp - you'll need to look at fuel system as well as turbo, of course exhaust is a must and remap

st3v3

270-280 bhp on a standard TDO4 for the WRX and that will give you high ACT's.

scooby51

thanks for all your input guys

Zen - could you PM me a roundish figure if I was to just give you my car or would it be better to shop around, get the parts and then give you guys a bell???

Cheers again

Good advice and best thing to do, Vf35 is great turbo. My TD04 made 286bhp on the rollers at Powerstation. 300bhp would be really pushing things.

daddyscoob

Why ask a load of total strangers who for all you know might give you either bad advice cos they don't know better or bad advice to wind you up.

Speak to someone like David at API - a proper expert and not out to rip you off.
Easy peasy and the best advice.

Sorry SN'ters but you know the facts - a little knowledge is dangerous - speak to someone who knows

andythejock01wrx

Ideally you need the get an idea from the consensus of individuals who have the mods you are after, at the same time contacting a few of the best tuners in the market. One retailer may simply tell you what he or she sells !

Rudestickers

My TD04 pushes 296bhp ATW, great little turbo spools up quick and has been reliable for the past 34000 miles,

whats wrong with using the vf34 ??

A friend of mine has an 02 WRX running 357bhp/310lbs

Daddyscoob - stop hijacking my thread

If you havent got an answer then dont post. Thank you

The reason I'm asking is I have an idea of what needs doing and by asking fellow snetters, i'm confirming what needs to be done. If someone has gone about it a different way or used different parts to achieve a similar result, then it could be worthwhile exploring that route.

I've got a MY02 UK bugeye wrx with PPP made 260bhp the other day on powerstations rollers. I am looking for between 300 and 320bhp with similar torque so I have bought.

Stainless Headers with Up-pipe with Wrap
3" turbo back system with open neck downpipe (full decat)
STi Pink Injectors
Uprated Fuel pump (well will have it before it's mapped)
VF35 from an 02 STi

Obviously it will be remapped when it's all bolted on.

But im not sure if I was to go for an STi tmic as well, would it make much difference ? what do you guys think ?

p.s Sorry for the slight thread hi jack

For the year/model you wont see much passed 270-280 on a standard TD04, you can push harder but then internals on the MY99/00 engines have been known to let go beyond 1.2-1.3bar (pistons break), newer TD04's are slightly different, they "may" push more power but you need a hybrid for that really and in all honesty your still loosing out top end where a bigger turbo will carry on.
What you dont want to be caught up in is the 300+bhp competition, there is 300bhp and then there is 300bhp, both are 300bhp but one is quicker than the other, simple reason is that you have 2 ways of getting there, the one that gives you the most torque will give you the better performance, and that wont be the TD04.
(its about the delivery )

All those bits wont do anything for you if your still resticted by the turbo....
