looking into getting my car above the 300bhp mark in the new year possably and i was wondering if a grand is enough to do it with, already got a turbo back decat exhaust,sti panel filter and walbro fuel pump fitted and mapped using ecutek.

Assuming new/minty used

Decat Uppipe £100 (for torque !)
3 Port Boost Solenoid £50ish
VF35 - £250ish
STi Injectors - £250ish
STi Top Mount/tray/scoop - £350ish
Labour - 4hrs ish - £200
Map £150-300
Proper fluids, no halfords shyte !

Potentially if you find some bargains. but do it properly.

Personally I would aim for a genuine* 280 with good torque, save money and gear box.

Are you good with your hands??

Labour can be saved as nothing there isn't impossible to do with a set of tools

you have the sti scoop i believe. the undertray can be modded easily to fit the sti top mount.
You can pick up sti pink 2nd hand for £120
Sti top mount 120-180
decat up pipe 40 (bargains are defo out there) not not get the flexi joint ones
map 300
VF35 is a good turbo

£1000 is defo possible mate

you wont need to worry about box or engine at the 325/300 mark imo.

ye i have the STi scoop fitted now,wish i was confident enough to fit the rest of the things my self, i think the 3 port and top mount may be do-able but as for the turbo and up-pipe ide have to have it fitted. my mate is a very good mechanic though (team subaru driver at sso and totb)

im already running 273/270 so as far as going for 280 i think a grand is a touch steep for 7bhp

you both have suggested the vf35, is that they way to go over the vf34

Full Decat or Sportscat exhaust from turbo back 2.5 or 3” bore.
Decat uppipe Pre turbo
Walbro 255 l/hr uprated fuel pump
K+N panel filter
Ecutek Custom ECU recalibration
Twin boost set up for high/low power switchable in-car
vf34 turbo
High Flow multi spray fuel injectors 550cc (380cc as std)
Uprated turbo to intercooler 'Y' pipe
NGK PFR 7B uprated spark plugs

taken from andy,fs website this little lot will go nice on the road and save your clutch and gearbox and power wise around 320/330 as for the gearbox lasting depends on how you treat it ie, track or so

Wouldn't cost a grand though and the torque would be worth it easily !

powerwrx

iTrader: (11)

is the uprated Y pipe really needed, not bothered about the twin boost set up, the rest seem reasonable enough to get hold of. as ive stated some of the above i alredy have so that will keep the cost down although he recommends the vf34

powerwrx

iTrader: (11)

how would i go about getting a genuine 280 with good torque, what would be needed

playtime

iTrader: (1)

i wouldn,t bother with the y-pipe your standard one will take 330 no probs

your standard turbo will get you to 280/280 i have driven a remapped wrx with the turbo standard turbo and it really is excellent here try this

iTrader: (41)

I *in bold mate

Definitely do the STi intercooler though (which has it's own Y pipe) for increased flow and torque. You will be surprised at the benefits of the uppipe decat too !

powerwrx

iTrader: (11)

fairenough...are we talking a noticable gain from the figures i already have

53

iTrader: (41)

Yes.

DaveBeck

iTrader: (12)

IMO dont bother doing it unless you up the turbo. you WILL regret not going for the bigger turbo at the time. Granted you can do it at a later date but then you would have paid 2 remaps.

Im talking from experience mate as i started out on a remap td04, then the vf35, then td05 18g now i have a 2.5 built lump on a 20g. remap next month on 20%E85.

Really wish i had missed the in between bits and gone big straight away as i would be alot richer lol but its something you learn from modding

VF35 will spool earlier than the VF34 but the 34 has more top end grunt. plus its roller bearing(34)
I would go 35 only because of cost.

35's can be picked up for 200 on ebay while the 34 hold their money well.

Not sure who your usual mapper is but defo worth having a chat and explaining your plans.

New oil and plugs is a good idea to while your there as mentioned.

53WRX is right but imo you will regret not getting the turbo

HTH

powerwrx

iTrader: (11)

yeah i know what your saying, ill probably regret not getting a turbo, then ill more than likley want one after a few months.

JGM is my chosen mapper so with any luck he will put his 2 pence worth in at some point

53

iTrader: (41)

^If you can afford it defo do the turbo, but what I like to suggest makes the very best of what you have already at minimal cost. Basically, in terms of intercoolers, turbos and injectors, the more scope you give your mapper in terms of charge temps, boost and fuel the more your gonna get. But more importantly, as we are all more sophisticated than hunting headline figures, increasing exhaust flow and intercooler size will allow increases in torque and BHP throughout the map which is fundamentally where you will see 'noticeable gains'.

iTrader: (41)

Simon will see you alright Will probably recommend the VF35 or 16g but he'll give you a realistic idea of whats possible without changing the turbo too

powerwrx

iTrader: (11)

very true

powerwrx

iTrader: (11)

thanks for your input guys...ill have a chat with simon as he already knows my car and see what he reccomends (within my budget that is)

DaveBeck

iTrader: (12)

Simon has done all my maps. Knows exactly what to do to get the most out and be safe.

Good hands indeed

keep us informed mate

powerwrx

iTrader: (11)

will do, like i say though it wont be till next year before i start moding again..

A ran a very good 340bhp & 340lbft in my old wrx with the following parts.

Full 3"milltek decat system
Walbro 255 fuel pump
Ngk 7b plugs
K&N panel filter
Air flow delete elbow
VF34 from Andy forrest
STI up pipe
STI tmic
STI scoop & undertray
STI 550 pink injectors
Ecutek Custom ECU recalibration
Twin boost set up for high/low power switchable in-car .

This makes a great fast road car although i think at this sort of power you'll be on the clutch & gearbox limits.

But then again i done a 1/4 mile drag day in mine done 10 runs with no probs & the best run was 13sec at 105mph and that was without luanching the car.

powerwrx

iTrader: (11)

sounds good to me although ide probably go for a little less maybe have it mapped to 300-310 rather than go all out for as much as it can handle..ide prefer a bit less and a safe engine

Wulsey

iTrader: (1)

That was running at a safe 1.5 bar of boost & Andy F always maps on the safe side & has a good past record for being kind on the engine.

Wulsey

iTrader: (1)

A mate of mine has his bugeye wrx running 300bhp & 315lbft with all the mods listed above apart from the turbo & injectors.

So if your looking for these sort of figures you might not need to go for the turbo & injectors.

But the best bet would be to speak to Simon at JGM & see what he says.

powerwrx

iTrader: (11)

really...i wasnt aware that the standard turbo was caperble of that sort of power

DaveBeck

iTrader: (12)

TD04 cant make 300bhp

Andy Forrest TD04H is cappable i believe but stock turbo defo cant

Wulsey

iTrader: (1)

The car was mapped by wallace performance and at the last rolling road day your club had at DASTEK it produced 300bhp, i was there & saw it for my own eyes.

My old wrx ran 283bhp with the decat exhaust, fuel pump, 7b's, k&n panel filter, and stage 1 map from Andy F the same day.

DaveBeck

iTrader: (12)

Surrey?

Sorry mate not calling you a liar. never heard of one making that power and been told by mappers/tuners its impossible

Wulsey

iTrader: (1)

sorry mate that was ment to read our club (ayrshirescoobs.com) .

I was always lend to believe this too, but then again whos to say the rollers were reading right.

DaveBeck

iTrader: (12)

I wouldnt mind going to them rollers lol
