hello fellas, i have been reading lots of previous threads and doing searches on subarus and getting myself all confused!lol (its not hard!) Basically I want about 270 bhp from an MY99/00. I understand it is achievable with exhaust/filter/chip. Please could someone list me EVERYTHING i would need. I have heard about different chips/boost controllers/dump valves/maf sensors/knocklinks/all sorts of crazt things! In an ideal world what would i need to run 270bhp with stable boost + safely! inc any gauges etc which are compulsary in your eyes!
Thanks in advance!
Paul

 

A complete de-decat exhaust,A panel air filter(green or k&n) and an ecutek remap will see you to around 270ish.

As for gauges i think I'd like to have a knocklink on any car with modifications but there really all optional.

 

heres my mods whih i have run 273bhp and 265lb/ft torque which i was run on sva imports rollers

decat downpipe
centre decat
ninja backbox
apexi induction kit
dawes device running about 17psi
samco hoses
hks dump valve

knock link
boost gauge

 

am i right in saying the dawes device is a manual boost controller? if so, do u not have to upgrade the ecu in any way? whats the max boost u can run on a standard ecu with exhaust and filter with increased boost using a dawes?

depends what ecu your car has as they have different fuel cut levels (on the earlier cars anyway).
I personally wouldnt run a car at additional boost (by using a dawes or other kind of boost controller) on the standard ecu for prolonged periods of time as the fuelling will probably be running lean at the top end.
A remap will be the safest way of increasing boost, probably smoother power delivery and also probably better economy as well. (along with the other supporting mods, decat exhaust etc)

 

so if u change the ecu, do u still need a dawes type device? is this just to make sure u retain high boost type thing?

 

Uprate your fuel pump as well as the ECU will demand more fuel. I am about to upgrade my WRX 01 UK with a Ecutek, fuel pump. Already have WR Sport bb and HKS Hybrid panel. Hoping for plus of 250 bhp at Powerstation, they recommend the fuel pump upgrade.

Your on the rollercoaster now!!!!

 

if you have an aftermarket ecu like the power fc then it will be mapped to your car, this means it will have custom fuel and boost maps so you have the correct fuelling for the boost levels that you run, so no real need for a dawes device imho, although some people do still use them even with an aftermarket ecu

 

so far then....exhaust/panel filter/ ecu (apexi pfc/ecu tek) and fuel pump ? then a knocklink if i want and a boost gauge?

 

Thats about it,The ecu is the big factor.Which one to go for ecutek re-map of existing ecu or apexi. I'd have a word with Andy.f as he does both systems so can probably tell you whats best for you car.

 

thanks mate

 

so your moving over to the darkside then Clarkie!!!!!

 

knock link i would say is a big must ! it will tell you if your getting any det! you do not need a remap if you go for a decat! the remap is to make sure your getting your max out of each part more safely

 

yes fred i am mate!lol

i want to increase the boost too tho mate so wouldnt i need ecu? how do ppl get to 270bhp, is that mainly due to increasing the boost pressure?

 

renaults and scoobys are different ball games Clarkie

you spend £4K on a renault you get 210bhp

you spend £4K on a scoob, and i'd guess you be over 300bhp

 

i no mate lol. i have just been reading a thread from a while back with a clio and a saab i think it was racing, and turned into a massive argument about CS and SNet!

 

If you had the car mapped using ecutek, they increase the boost safely , So you would either need to buy a new ecu or have your exsisting ecu mapped, or you could use a manual boost controller, But getting your car mapped will also bring out the best in your mods to your car, and buy far the best mod you can have done to your scooby.

My previous car was a MY00 turbo 2000 had the following mods done to the engine and was running over 300+bhp,

VF23 Turbo
APS Intercooler
Uprated fuel pump
550cc injectors
full Decat
Panel filter
Dump Valve
EcuTek remap

Didnt cost much to get that sort of power, think I spent about £2k, bought most of the stuff in the for sales section on here.

 

is ecu tek a piggy back or stand alone ecu?

 

Ecutek is the original ecu reflashed with new data and then adjusted to give your car the best and safest performance possible for any modifications you might have.
So its not a piggy back nor a replacment ecu

 

If you fit the Apexi power FC you can use the CEL light to monitor det,
that will save you around £150.00.

the power fc is that the portable commander thing? do i need the apexi ecu for this then i take it? all these diffent products, im getting all confused!haha

 

the power fc is the ecu man fc meaning full computer, the commander is the portable commander
