This is the set up i am planning and i just want to know what the max BHP and Torque i am likely to get from it.

MY99 UK Turbo

Standard Internals
FE TD05
Full 2.5" Decat Turbo Back
Apexi Power FC
Apexi AVC-R
Knocklink
Boost, AFR, Oil Pressere & Oil Temp Gauges

Maybe

Sti Intercooler

Is it worth while getting the sti v5/v6 intercooler for my car i have heard they are a straight swap but there are mixed reviews to whether they greatly improve cooling over the standard item

At a guess - 300/300 @ 1.2Bar

The intercooler is the same, but if you can get hold of the aluminium STi manifold underneath that's well worth it. Grade A will do you one for £75.

Without changes to the exhaust manifolds you'll be lucky to get past a genuine 280bhp. Personally i'd recommend the VF34 turbo, but from what i've heard, the TD05 is adequate.

John Banks comment

"Sounds good for a VF34, but you should do better with a FE TD05. Try one, you might like it, and you'd never consider a VF again except perhaps the twin scroll versions or VF35 if you needed quicker spool up. And then if you get bored of it put a 20G compressor and cover on it and you'll get 121 mph traps like I was on this turbo."

So you reckon i get the sti intercooler manifold and a set of headers (would have to be unequal).

What sort of BHP/Torque figures would i be lookin at (Reliably) ???

I want around 330 bhp

MAFFA

On a MY95UK with a 3" decat, dump valve, induction & a 15.5psi scoobyecu chip I pulled 311.5BHP with around 275lb ft

Wonder if this'll start the "that's not possible" argument again? LOL

Oh & yes it was running 380 injectors

MAFFA

Andy.F

Of course it's possible (on some rollers )

Andy

heple1983

So does the setup i mention look like its capable of 330bhp

TelBoy

Nope, not in my opinion and experience.

TelBoy

Yes, get the manifold and some headers. You say "have" to be unequal - is that to preserve the engine noise? If so you'll sacrifice about 10bhp, but you should then get over 300 comfortably, on an accurate rolling road. Although i have to say, i'm not too familiar with the exact capability of the Apexi unit and controller - mine's a much more basic Unichip and Dawes, but with all the other bits and pieces, on 330 injectors, still makes 325/320 on Optimax and NF. Having a target in mind is all well and good, but apart from pub talk is it really that important? Any Scoob over a genuine 300 is plenty quick enough for most people...

No its not.

STi5/6 intercoooler was designed for a 276bhp car (+safety margin)

MY99/00 uk intercooler was designed for a 215bhp car (+safety margin)

Everything is built to a price.

Dont think you'll get a true 330bhp with that spec.

Here is what is going on mine:

FE-TD05
Gruppe-s V2 Headers & uppipe
3" Straight through turbo-back exhaust
STi7 Intercooler + Scoop
Exedy Organic Clutch
ACT Prolight Flywheel (4.2kgs)
STi Panel Filter
Airbox mod
HKS SSQV
Walbro 255 Fuel Pump
FSE Fuel Pressure Reg
3-port solenoid
Tek3 or Apexi
std 440s

Knocklink
Lambdalink
Blitz Boost Gauge

Will be running it on Optimax and NF.

I would be happy/lucky to get a true 330bhp on mine.

You may need to consider injectors, fuel pump/reg, breathing. You'll also need an uprated clutch.

you'll need a lot more on that spec sheet to run 1.2bar safely.

as a minimum I would also include walboro fuel pump and uprated regulator.
next up would be a good filter.


its all in the mapping

heple1983

Cheers lads thats a big help.

I dint think i was gonna make 330bhp just wanted to see if i could.

But at least i now know what i need :

FE TD05
Aftermarket Headers
STI 6 Intercooler
Fuel Pump & Regulator
Air Filter
Turbo Back Exhaust
Apexi Power FC
Apexi AVC-R
Knocklink
Boost, AFR, Oil Pressere & Oil Temp Gauges
Injectors (Although Not Sure if i need them (Not sure whats on my car))

Cheers for the help!!!

MY99 UK Turbo has 440c injectors

Rule of thumb is c. 5cc per hp => ( 4 * 440 * 0.85 IDC ) / 5 = 299 hp

heple1983

So they'll pretty much be on there limit then??

What are the STI ones capable of - i've seen a few sets on ebay

stevebt

iTrader: (8)

your car will be fine on 440 injectors mine was i only changed to bigger injectors when i went with a bigger turbo the intercooler is the thing that will ruin that setup as it will keep your power down

heple1983

What intercooler would you recommend then ??

Andy.F

Sti 7 onwards for circa £200 or a hybrid frontmount around £500.
The AVC-R, although a 'nice to have' is not essential for this power level, It can however result in a faster car on the road if the in-gear compensations are properly set up.
The Apexi Power FC is more than capable of controlling the boost on a 99 car.
The 440's at uprated fuel pressure will keep up with anything a td05 can flow.

Andy

Is the STI 7 Intercooler a straight swap??

And will i need a bigger scoop ??

Aztec Performance Ltd

iTrader: (234)

It requires some work to fit. Can knock against the bulkhead also (noisey)....ask stevebt. And yes you will need a bigger scoop

Bob

TelBoy

Bob,

I'm happy to be told otherwise, but apart from core configuration, these two intercoolers are identical, save for the silver coat of paint. I'd be interested to hear what you know about them to be sure they're different. They certainly don't perform any differently.

heple1983

Right so am i best stickin with my standard intercooler or gettin the STI 5/6 Intercooler???

TelBoy

If you want *real* improvements in intercooler efficiency, you'll need STi7/8, or FMIC.

In my own opinion, changing for a 5/6 isn't worth the expense and hassle. What i would recommend though, is an intercooler splitter on the bonnet air scoop - that definitely seemed to help, especially on warmer days.

heple1983

Also would getting my headers ported be enough or will i be better with aftermarket headers???

Am only looking to break the 300bhp barrier am not gonna be after crazy power

Delboy2

Ported headers and up-pipe would be good enough for breaking 300hp

Cheers

re: tmic....
with experience
stiV is better than uk99 because as Tel points out the core configuration is better.
They also utilise an alloy Y section and a better quality samco type elbow.

re: headers
ported will be good for a bit more torque and maybe a touch more power, tubular will be good for a decent torque rise but at about 5k rpm upwards.
ported headers keep the power band at a sensible level.

heple1983

Cheers lads thanks for all the help!!!

Knowledge is power - In this case literally

Aztec Performance Ltd

Dont know the exact tech differences but I do recall some of the techies recommending the STI5/6 over the MY99/00. If you look closely, the size of the top tank is different.

Also people have achieved more power using the sti5/6 i/c over the my99/00

I would be happy to run 320-330bhp on an STi5/6 i/c, whereas I wouldn't be happy to do so on a std my99/00 ic.
