Hi,
how can I increase the BHP? MY99 UK Scoob, full decat exhaust,Tek2 and K&N panel filter fitted. RR 267 BHP 269LBS/FT Torque.I would like to get this upto 300,what is next FMIC,turbo or a remap?Any advice and rough costings would be very much appreciated.
Thanks
Merv

You might - if you're lucky - get close with a manifold. Stephen Done managed it with very similar to yours (in fact it's why the Tek software was developed in the first place 
) but just with a JUN (I think!) manifold. If you think 300 will do you, that seems to work well (you keep the fast spooling little turbo) - but it's a dead end then.
The turbo is the easiest route, although that will then require a remap as well. An FMIC is unlikely to be necessary, assuming your TMIC is in good nick with a larger turbo.
VF23 would be the traditional route, although others would say a TD05. But at this point you need to think a lot about where you might want to go - 300 now then turning to 350 shortly afterwards could change your choice of turbo!

Thanks lads,your right once I reach 300 I'll want 350. So if I was looking to up grade the turbo can the Tek2 be remapped or would I have to change the ECU?What about injectors and fuel pump if we are going to up the boost pressure?
Chrome what power your car running at with that turbo?

For 350, the standard injectors on the MY99 are fine, although it would be sensible to get a better fuel pump - 350 would be very much on the edge for the 440s (and you'd only want to be on the edge very briefly at that!).
The standard (ie Tek type) ECU is happy at that sort of power.

My recommendation would be a TD05 hybrid with front entry, uprated fuel pump and uprated fuel pressure regulator.
We've mapped 3 99s in this spec and they produce 337-343bhp.
You will also need to uprate the pipe from the turbo to intercooler, as this has burst on 2 of the 3, so we now insist this is also changed.
The car is very quick in this spec

Ross,
I have similar mods to yourself but have not run the car on a dyno. If you don't mind, could you tell me whose dyno you ran your car on and what boost you are running?
Cheers,
George.

The 440s can do 350 with a steady fuel pressure (uprated pump) & especially if an uprated regulator is fitted - can do wonders to the consistency of fuel flow (making mapping easier & far safer) and also increase 440s beyond their rated capacity, as the rated capacity is at a certain fuel pressure (3 bar?) so increase to 4 bar & you effectively increase the size of the injectors

Hi Ross.
Thanks for the info. That's great power and sensible boost too. Quite impressive. It gives me an idea at least of what power I roughly have.
You are right. We have two Optimax fuels here. The plain Optimax called "V Power" is 96 RON and the Super Optimax called "V Power racing 99+" is over 99 RON.
Prices are,
NUL 0.65Euros (0.45GBP)
SUL 0.74Euros (0.51GBP)
V Power 0.70Euros (0.48GBP)
V Power Racing 99+ 1.09Euros (0.75GBP)
As you can see there is a big big jump in price for V Power racing for Greece's standards of living.
This is why I sometimes think that Optimax in the UK may be 96RON. I think this because it is cheaper than SUL over there like it is in Greece. The 99+ Optimax here is much dearer than SUL.
Cheers,
George.

The latest cranks have cross drilled oil ways, which should help eliminate big end failure. As discussed in a recent thread though, meticulous servicing proceedures are required and no amount of additional oil feeds will stop a dry big end from becoming damaged.
Tuning to this sort of level has been around for some time, but now its possible with all of the standard ECUs safety features and compensation maps. Both Andy Tang and Top Cat were running around 350bhp from 97/98 cars, reliably and over a considerable time/mileage. John Banks has been running over 400bhp from his car.
The most we have taken a new age car to is 380bhp. This was a WRX. We have done a few STis to near this output, but most are at the 340 mark that the STi achieves so easily.
I drove a 340bhp 99 UK on Tuesday night. Manic, det free power that sees you charge round the right hand side of the speedo dial. The biggest danger seems to be to your license!!

Pete,
what's the best upgrade path for a completely standard MY01 together with approximate costs ? I want to achieve in the region of about 280 - 300 BHP but obviously prefer more torque or that punch in the back. Ultimately i'd prefer an STI but if my WRX can be upgraded so it's slightly quicker off the mark
it'll make that grin on my face even bigger
thanks,Jai

Hi Jai
EcuTek and our exhaust will achieve 285bhp and c270lb torque with safety. We have done a lot of 01-03 WRXs to this spec.
Its just not comparable to the standard car. 1 bar is achieved by 2600rpm (just over standard boost) and full boost (typically 1.25bar) from 2800 upwards. The standard car tails off dramatically after 5250 rpm but we hold good torque to around 6300. The difference in the power band means you need to change gear much less often, especially when blasting country lanes. The power is also very controllable and you don't get full boost/power unless you are asking for it. This makes the car a joy to drive on the limit.
I'm running a little bit more than this on my car (in the interests of science
) and even this has a good safety margin. 300bhp would be on the ragged edge of what the injectors could cope with and we don't want to push them that far, especially when they are so good at 285.
Price is £1899 inc, all fitted for the 01-02 WRX (includes new de cat up pipe) and £1598 inc on the 03 (no cat in the std up pipe). The work takes approx 6-7 hours on the 01-02 and 3-4 hours on the 03.

Hi Pete !
Definately interested in your proposal - i think i need to do some handling tweeks aswell - I know you do a leda suspension but would it really make that much difference ? I need to be convinced on spending £1k+ on a new suspension !
Can any further increases on torque be made past your quoted figure above ?
Does your price of £1899 include anything for the exhaust ? I find the standard exhaust does not do the car any justice and I want a more deeper flat 4 burble coming thru !
Thanks, Jai

Hi Jai
We can't improve on the torque figure with the standard turbo, whilst still retaining a good safety margin.
The price includes our full exhaust system and fitting.

Hi Merv
Just a small question for you M8.
How much are TD wanting for a VF34 turbo now, i was quoted a price a while back and seem's to differ from the price now.
Mail per profile if not wanting to go on line.
Cheers Dougie

Pete,
The 340bhp my99 you drove...was that figure achived using your exhaust/ecutek package plus an improved turbo?...plus a new fuel pump and regulator presumably?...and headers...just wondering on the costs to get to the 340 mark.

Hi Wrexy,
I ran the car on Clive Atthowe's Dyno. Peak boost was 17.5 psi @5500rpm tapering off to 15.3psi @6700rpm. I will put the chart up here if I get a chance later. Hope that helps.
Also, just out of interest I saw what looked like super Optimax in Athens last week. What RON is it??

Pete,
What are the main differences between the internals of the ST1 7-8 and the MY99?...with a MY99 handling this power I was wondering about its ability to withstand it! I was thinking about buting a STI8 or MY03 wrx (both with ppp fitted)...but now wondering if MY99 tuned to this sort of level would be more fun!..excluding warrantee issues...
Also...what would a STI8 push out if tuned to this sort of spec?
Cheers
