Whats my next step in advancing my sti

[Caleb 895/1000]

Ok so basicly im after a list of what i should do next, so far i have a V4 sti with...

Hdi electronic boost controller

VF22

FMIC

Standard ecu

Walbro 500hp fuel pump (not installed... can i install with out new ecu?)

Full exhaust 3" (by memory)

Tial 38mm external wastegate.

So pretty limited upgrades. I want what will get me the best gains at the cheapest... But dont mind saving up either for say a link...

Oh and if i had a link and a tune what is the average gains you get? More than 30kw?

And 1 more question... What is the advantage of a link to a chipped ecu? Will a link deliver more power... Im only wanting about 250-270kw maybe more depending on money etc etc

[off2harrys]

If you mean 250-270kwatw ul need a new turbo,injectors,pump n def a new ecu thn prob a 6speed sooner or later

[nt_a_foz]

For 1 you wont get 250-270kw out of the vf22. Max youl get is 230kw or there abouts.

If i was you id go for a link, youl get the best power possible out of that setup in the safest way, youl get rid of your AFM which is prone to problems as we all know. I personally wouldnt run a chipped ecu on something like a STI.

Link will develop more power and in a safer way plus when you change stuff on the setup its easy to retune it to suit.

Factory ecu you might be around 170-180kw at the wheels and with a link you should get 220-230kw or there abouts.

Ok so link would be my 1st upgrade before i start looking at twisted turbo set ups and shit? How much would that set me back roughly? Just a plug in not a complete wire in

[nt_a_foz]

Plugin G4 retail for about $1700-1800, then you need a airtemp sensor which is around $150, road tune if its not going straight on a dyno which can be $300 odd. Then dyno tune can be anywhere from $500- $9696959 depending on how many problems they have.

Link will make it safe for what ever mods you do if you get it retuned accordingly.

You can probably twist it and flip it but as seen in another thread AFM can have a bit of a hissy fit if your running the factory ecu and make it idle ruff etc.

[Caleb 895/1000]

OK and the difference between a g3 and a g4?

Im not real keen on a dyno aye... Been told they can do some serious damage to your car?

[Drunkenmonkey]

dont bother trying to push more power then as more power mean less reliable, its not the dyno that blows it its either the tune wrong, or the motor cant handle the power

[Caleb 895/1000]

ok i think ill settle for around 230kw

haha the dyno damages your car? its the driver that fucks it up.....

no mechanical sympathy is the demise of most subarus on this forum to be honest.

[nt_a_foz]

The dyno will mean you get a safe tune, if the tuner knows what hes doing i doubt its any worse than you sitting on redline in 5th gear thrashing the tits off it caues that sure aint good for it either.

'If you want good power nad it to be done properly put it on a dyno otherwise dont bother.

install the fuel pump it will not effect the tune.

The most cost effective upgrades is ecu and injectors. That will get you arround 230kw.

Standard engine ? How many km's

[Caleb 895/1000]

Yea 60 odd

[Guest]

The km's are pretty low - these engines have a knack of dieing over 100,000km.

What boost do you run to the redline ?

[Caleb 895/1000]

11psi 95% of the time and 18psi the other 5%

[Caleb 895/1000]

That was on rebuild tho... 183 on the body
