just had my 04 sti ppp mapped with ported wrapped headers, custom u/p 3"decat d/p, colder grade plugs, k&n panel filter and on v-power. dont get me wrong car feels superb but would of liked the figure around 365 but never mind.

 

I know what you are saying mate but its really what the car feels like to drive, thats the important bit not what the figures say.

 

that sounds pretty normal for a standard turbo, doesn't it?

 

That is a good torque figure, the power might be slightly low but it's the torque that makes the car fun to drive

 

With those mods, you'd need a JDM to achieve those figures.

 

What made you think you'd get more?

 

Probably someone on Scoobynet !

 

after my experiance with my 03 sti and what ive done with mine to what sort of figures ive had,your power figures seem really good to say what mods you got.ide be happy with that.

 

In another thread on here, a guy got 340hp/330Lbft with just a remap on a bog std stippp with no mods.
The ppp headers, sports cat etc must be good enough anyway then?

Good torque figure in relation to the BHP. Mines a similar spec and made 286 Bhp @ the wheels. Mines still running the Prodrive Sports CAT though

 

Is it that the torque isn't sustained for long enough which is giving the below expected BHP?

 

Next decision is who do I phone to remap my bog std 03 stippp to 330hp ish?

Xtreme scoobs ?
jollygreenmonster?
Mocom?
etc...

Mocom M8, your gonna need a few Mods to get to 330 Though IMO. Ported headers, CAI is always a good way to go

 

286 at the wheels would be fine.

 

Have a look at the Spec on mine Dave, all work has been carried out by Zak & Luke @ Mocom

 

dont get me wrong the car is a real hoot to drive now and i suppose figures are for the pub. the outcome was 343 allowing a 22% loss. shame about the loss.....411bhp would of been nice lol.

 

You should achieve that figure with just the PPP exhaust and the re-map?

I think those figures are very good, with the torque being slightly above normal for those mods.

 

Mocom'd

<<<<< VMS

At the OP, those figures sound good ! The nice torque result will make that BHP much more useable

 

Not in my experience u don't. I'm happy with what i've got now and appreicate i could get more by Decatting the downpipe but can't be arsed with the hassle come MOT time. As for the PPP Exhaust that was one of the first things i ditched as i found it to be restrictive and by changing it the turbo spooled up quicker and smoother

I've got a 3" Exhaust in mind, along with maybe some GTSPEC 2 Headers, and ultimately a MD321H, that should see me up to around the 400 Bhp mark at the flywheel. That should suit me just fine

 

365 on standard turbo????????

managed 350 with my vf35

 

decat, induction kit and a remap on the sti should see roughly 330bhp. but bear in mind the figures people say you will acheive from a remap are always best guess cos every car is different.

i know of a classic uk that once decatted and remapped wouldn't run more than 245bhp, same map on another car ran high 250's without even tweeking it

 

iirc the 04 sti doesn't have a VF35, possibly a VF28..?

My vf35 is running somewhere around 340-350, but that's definitely the top end..

Still the op's figures are bang on average with torque slightly higher, as already pointed out..

 

35 jase

 

easy one ZEN ....

 

hmmm... now I've read stuff about those MD321H turbos oh dear

dipster

 

so what would be needed to get up to, say..370-380 im guessing fmic and turbo. would the 565cc injectors be ok?

 

I'm no expert-try the techy forum-but I'm sure a new turbo for starters.

 

I'd say just change the turbo to something bigger, and remap, that's all.

 

so not to drastic then really, what about the standard air box would that cope.
