Hello all after some advice on tunning. I got an 04 wrx and got a couple of quid to spend on it what would everyone recommend. Not gonna do it all at once but want to buy some tidy gear so wont have to replace it in the future. All ready got a forge dump valve, pipercross indution kit and magnex stainless exhaust from cat back 3" pipe. What else can i do to get my bhp up and my fuel bills to rocket. Some names of parts and prices (roughly) would be a big help

 

We need a budget in order to advise

 

a huge budgets at that as well

 

ok i got £500 to spend at the moment then about £500 in september and then £1000 around xmas. could get more at a push depending on options would like 400 bhp idealy Dont have to do it all at once would like to do it in stages thanks guys.

 

400 bhp will cost you a lot more than 2 grand.

this is just off the top of my head...

in no particular order..
injectors,
Turbo,
Clutch,
FPR,
Fuel pump,
Remap,
Intake,
sports cat or decat,
headers,

and possibly,
Gearbox,
Brakes,
Suspension,
Engine upgrade (pistons, rods etc)

and there will be more.

 

To get a reliable 400bhp with 'all' the necessary items for a powerful and safe car, then budget for £10,000.00 minimum.

 

What is acheiveable given his budget, then?

I'm guessing his car is standard, like mine.

I would prefer to leave the engine alone and just concentrate on braking and handling. My budget is the same.

 

Mines at 401.3 hp & 368 lbs and cost me £2000.00 in modes and £500.00 in mapping fees
You just have to hunt the bargains out

 

£10,000 wow i can get a re map for £350 been asking round. what else would you suggest on this budget then. Whats on your scooby then to give me some idea of what to buy? cheers

 

Al99 has covered pretty much everything. An uprated gearbox that will last longer than five minutes will set you back £2000 for a 6 speed or £3000 for a ppg kit, before fitting. A turbo that will make a genuine 400bhp will cost £1200. See how the bills start racking up. Then you have got brakes, suspension, clutch, exhaust etc etc.

I dont doubt you could do it for less, if you buy second hand parts and fit it yourself.

 

Id go full decat exhaust , TD05-16g Turbo , Walbro fuel pump and Ecutek map.

Id also use a fuel pressure regulator or even better fit a set of STi pink injectors. I reckon that would make a nice car and not very expensive really.

ok cheers lads very helpful shall start saving

 

neil: click on "view my scooby" next to this post. Made 353 bhp / 354lbft.

If I was doing things again, I'd:

* get a hybrid td04 turbo off andy forrest
* decat up-pipe
* ppp sports cat
* decat centre
* panel filter
* fuel pressure regulator
* fuel pump
* any 2.5" backbox (i personally like the ppp one)
* remap

That should hopefully break the 300bhp barrier, not be massively expensive and have oodles of low down torque.

 

I,v got a 53 wrx ppp and the mods on my car to get it up to 356.9 bhp and331lbft are:

walbro fuel pump
ful decat (up pipe down pipe)
af TD05 18g turbo
sti tmic
550 injectors
ngk plugs
gt spec headers
green panel filter
Andy Forrest remap

 

thanks for all the adivce lads couple of things whats the difference between a hybird td04 turbo and a af td05 18g turbo? is the walbro the best fuel pump to get? whats an sti tmic? thanks aslo found someone local who can remap he used to race impreza's and now he's got a garage landed.

 

The Hybrid TD04 is a good bit smaller then the 18g and should get you to 300bhp or just under. With an 18g turbo your wrx gearbox may not last as long as you would like but then again there are plenty doing it but to be safe id keep it at around 310 - 320 Which would be a 16g at sensible boost. The newage STI intercooler is more efficient then the others but for 300 ish bhp your own one should be fine IMO.

 

nice one mate
