got my 03 STI GL JDM Twin Scroll for a few weeks now.... already needing more power ....

should i go for a induction kit or a panel filter?? (i am getting it mapped)

my plans are :

STI panel filter or APS CAI
Walbro fuel pump
3'' Decat twin scroll downpipe with Heat wraped
3'' Fujitsubo Cat back exhaust
ECUTEK3 remap
upgrade 7s plugs ??

what else do i need??


what should all this mods give me?? will this give me more low down torque ??

many thanks

That's Kevs evening sorted lol

Have a read through the Newage Modification Articles HERE as it may answer a number of other questions and also give some other information.

But in essence....

Performance Panel Filter
Uprated Actuator
3 Port Boost Solenoid
3" de cat exhaust
Remap
Fuel Pump (if one already on car is not man enough)

As Gordon Ramsey says "Done!"

I acheived a tad under 370bhp and 350lbft with the above mods on straight Optimax, running decent boost.

Regards,
Shaun.

shaun, briefly, why was the actuator changed and for what purpose did doing that serve?

~DrEaM~

thanks webmaster

do i have to use a Uprated Actuator to achive those bhp and torque?
if so where can i get them on the net??

ex-webby

The standard actuator is too soft and found it did not hold the higher boost up the later stages of mid and top end rev range (you can try jacking the duty cycle really high, but even that does not have the same effect as an actuator with a higher "crack" pressure for sustained boost). If you want to hold the boost, you will need an uprated actuator.

Neilo

what is the actuator cracking pressure on your uprated one now?

IIRC your running around 1.7bar peak is that right?

ex-webby

I can't remember..... I think it was about 1.2bar.

Max peak is just under 1.8bar (weather dependant) and holds 1.6ish in the mid range to 1.3 at the red line (if I remember correctly on this turbo). 1bar at 2500rpm ish and full hoof at 3100rpm ish in 6th.

DrEam,
For information the above info (directly above) is not on the standard turbo though. (flaming edited again lol) But the power figures I quoted initially are.

Neilo

thanks thats cool, mine cracks at 1.25 bar and i was hoping to run about 1.6 so thats sounds perfect.

ex-webby

What power you hoping for mate? I bet you cant wait to get it mapped...... hope it goes well for you.

~DrEaM~

okay where can i get the Uprated Actuator from?

thanks

I got mine from PowerStation.

~DrEaM~

thanks... shaun.. so will i be able to get let say 355+bhp with the standard Actuator ?? and did you use some 8s plugs?? or standard 7s ?

Neilo

hell yeah!

similar to the new T25 all being well, so about 410 would be nice, it certainly feels a lot nicer even now. Im certainly going to be giving it every chance anyway, a 10% meth mix to get some decent advance out of the engine, as my current map was deliberately very flat for the initial use with nitrous. Which i now no longer have, so can run much more now

gearbox shredder hopefully

sorry ~Dream~, didnt mean to hijack!

Neil,


DrEaM,
350bhp is possible on the standard actuator (if it's a good 'un). Standard plugs, even now.

I have 355 with a zorst,filter,3 port and remap... NEED more now tho...

I cant remember what I have



You should get close to Spec's car with the standard turbo. His one will be a little bit higher that you should expect as the C's have a better inlet tract and a roller bearing core to the turbo.

Its still damn nice though.

Hell, I'd like some of that!

I acutally spoke to one of the NGK guys at autosport this year asking what would be a good replacement for the spark plugs in my car, he basically said they aint worth changing as they are pretty damn good
Not sure how far you can take them though....

Tony:

PS where did you get the uprated actuator from Shaun?

Tony as earlier, shaun said he got it from powerstation.

hopefully i will find out what the max bhp of a hybrid twin scroll is next week as i have made a few more changes to the car and will be going for a tweak, apart from aftermarket headers there is nothing more i can do to the car for the remap !!

ex-webby

You could get 600+bhp from a twin scroll if you wanted.

i dont think anyone makes a twin scroll turbo that big ??? it would of been fun to try one as i wouldnt of had to spend all my cash on a garret

SPEN555

How? By running two VF36/37's

Neilo

nah just a standard one and a 200 shot of nos itll only be 600 for about...oooh.....2 seconds, but itll get there

You wanna a bet!
