On MY06 STI Im looking @ getting a little bit more from it , as it stands now

K&N typoon cold air induction kit
3" decat stainless exaust system
Tech 3 re-map
Ported turbo
346bhp/375lb


Now without going "to far" what would you do next ? I dont want to be replacing engine parts @ the mo but is there anything that can do done to add a little more

Opinions please

 

You could get a boost controller with gear specific boost profiling to get you more HP in the lower gears. It won't add to the headline figures but should make it quicker.

 

Small upgrade - headers

 

Thank for the quick replys guy's ...

Jay could you recommend one ? Just had a look around & loads to pick from but is there any to stay away from ?

@ Varboy , thought of this but would need a re-map when fitted + equal or un-equal ? what would be the best ?

 

Isn't 06 STI twin scroll? I thought the OE twin scroll headers were really good.

Re booster controller my choice is the Apexi AVCR, but that to compliment the ECU I have. Best ask your mapper

 

No mate not twin scroll ( well 99.9% it isnt lol )
Dont want to go back to where it was mapped TBH as it's a long way from here + not happy with other things that happend there ( another story )

Cheers Jay

 

Apexi AVCR still the best one imho.. allowing as Jay says gear dependant duty.. basically there is less load in the lower gears so the duty can be added to make target boost in the lower gears.. and you have a gearbox that can take it too

Thank for that info Simon , but am i right saying this could give more lower end ? IE: beeter for a 1/4 mile run etc.... ? also is it a single din unit ?
And were can i get 1 from lol cheers guy's

 

it is smaller than a single din.. well thinner..

yes.. better for 1/4 as you get full boost in the lower gears etc..

 

You could, of course go the other way and go the suspension route, going for a strut brace, lowering springs and rear drop links to sharpen up the handling a little more?

 

yep or brakes!

 

Best value for money mod I have done so far is a set of Harvey Smith ported headers and matched up-pipe. There is torque lower down and everywhere else and it is freer at the top. On a run it may be using less fuel and it is certainly more willing to go even on a whisper of throttle.

 

take the rear wing off!!!! lol

 

ALK.

 

Sorry guy's i only posted engine mods .... Drop links / brake's etc.. have been done already

Thanks for the replys again .... still not sure now where to go

Looking like headers or boost controller , headers would mean a map tweek tho hummmm

May go for the B/C now & wait untill summer when i can do injectors & headers @ the same time ... oh & likein the sound of the MD321H aswell



Oh BTW steve , would takein the rear wing off work then maybe paint it red

 

lol @ paint it red

 

If you are fitting headers, you might as well fit a bigger turbo as well to see 400 bhp (+) and you will need a re-map for sure.... I am later this year when it's drier and warmer...

DunxC

 

Why not get it remapped again anyway? those figures seem quite conservative for the mods list ?

 

I will be getting a map but car'nt see the point in doing it after the headers have been fitted then again ( when the cash is there ) if i go down the MD321 route so looking for something to add now untill i free a little cash These cars eat some much cash!!!!! but ya gotta love em

RR printout......

 

Oh BTW steve , would takein the rear wing off work then maybe paint it red

it might reduce drag, but painting it red is probably not going to do anything for your cause, especially if you paint it as badly as i did mine last year!!!lol

 

Apexi AVCR on order from flat4 thank guys

 

Yea Thanks guy's my bank balance as just dropped a bit
