Axe-Hammer

Hey guys, this is my first post and I'm sure this has probably been asked a lot on here, but every thread i read just seems to turn into an opinions thread with no real fact.

Right, Ive narrowed my next purchase down to a hawkeye sti or an evo IX. I don't want any opinions on that but i prefer the looks of the scooby but performance wise the Evo has it.

So basically what i wanna know is, what will it take, and how much will it take to get the 2.5 into similar performance areas? i.e 0-60 around the 4's and near on 400bhp?

Its going to be an everyday car, and i have no problem adding a front mount and new turbo if need be, aslong as it remains fun to drive and not laggy.
Sorry for the essay, hope one of you guys can help out.

Free flowing 3" Exhaust (£500-900) and ecu remap (£500-600) will get you close,about 350-370bhp?

Plenty to take on the evo 9

You may also want Prodrive springs (£240 plus fitting), Walbro fuel pump (£75) and uprated pads (Pagids for about £250 all round iirc). From what I can gather uprated intercooler & plugs aren't required if no turbo change (perhaps others will correct me).

I've been looking into this too. Think I'll prob end up spending £2 to £2.5k as I'll get a garage I know through Andy F to do the work. Not fussy about colour as long as it's black. Would prob powder coat the gold wheels though !

Thats just the answer i was looking for, what is the limit of the 2.5 as far as bhp and torque go? Is 400 about it?

Im just wondering if i will need to forge it if i decided one day that i want more. How much extra will forging the engine cost?

Cheers guys.

And yeah, i gathered i might need to give the suspension and brakes a little helping hand, do the prodrive springs make that much of a difference?

Standard Internals 400bhp is tops (with any kind of chance it will not grenade in 5k)

If you're eventually wanting more, then maybe look at a JDM 2.0 and mod that

Re the prodrive springs, well, they were a huge improvement on my WRX. I've heard that they improve the STi quite a bit too (although would have thought it was firm enough?). Maybe someone with Prodrive springs on their Sti will comment?

From what I've been able to acsertain, with the std turbo you're looking at anything from 340/360 to 360/390 (bhp & ft/lb), depending on mods and how conservative the map is/who the mapper is. To get nore you need and TD05 20g, or even an MD321, which is big bucks (ie engine work)!

scooby L

I donlt think the Prodrive setup is any firmer than the Standard STI springs.. but (well on the blobs anyway) they increased the ride comfort as well as decreasing "choppyness".. plus the ride height's 30mm lower

To be honest i think around the 400 mark is all i'll ever need because i don't have any real plans to do track work or anything, just a nice fun road car that i can use everyday and can compete with anything on "my private roads" that i might encounter.

Once a decent flowing exhaust is fitted, do the 2.5's have the trademark Scooby burble? My brother had an unmolested blobeye sti and it lacked it on tickover i think.

Its easier & far cheaper to get an Evo 9 to 400bhp plus than a Hawkeye Sti. But if your happy with approx 370 bhp & similar torque levels then go with the Scooby. But if you'v want to go to 400bhp & beyond & want to spend less money doing it, then the Evo is more cost effective in that respect.

Shaun

Don't get too hung up about 400bhp EVO's. Most of the figures quoted are based on some weird and wonderful wheel to flywheel calculation. 400bhp at the fly on an evo, relates to around 310 at the wheels. This wheels figure on a Subaru would relate to around 380bhp at the fly.

In essence, if you are comparing peak bhp..... then a scoob with 380bhp at the fly would be actually putting down the same kind of power as a reputed EVO at 400bhp would.

Ah well thats settles it, go & get a Scooby!! New things you learn everyday on Scoobynet. ps...that means my 345bhp/385>ft/lb Spec C will eat a FQ360 for breakfast Shaun!!

Axe-Hammer

Cheers for that Shaun, but isnt an evo running the same power as an impreza quicker?

Shaun

Is it?

scooby L

All the UK cars (2L & 2.5L) have the burble... they just need an exhaust to release it!

an evo 9 is easy to tune if you got a fq320 all you would need is a downpipe an decat and a bigger pipe from the airbox to the turbo then get it geekmapped to 1.8 bar 400bhp plus no probs i hear they will run 450 at 2bar, i love scoobs but the cheap tunning on the evo shouldn't be overlooked!

Axe-Hammer

From what I've read (and this is only reading) the Evo is quicker. On paper the STI is slower than a similar specced Evo.

Let's avoid the out and out Scooby v Evo thread!

Axe-Hammer

Indeed, so basically, with about £3k spent on the STI i can have a car just under 400bhp, with good torque, and uprated suspension and braking.

Sounds good to me, i really do much prefer the look of the scooby.

Cheers for your input guys.

To me a 400bhp Evo is nothing like a 380ish Impreza.

The Evo just feels like it has a Civic turbo motor bolted in with AWD, revs up quick, but just no where near as torquey as the Impreza feels.

Just much prefer the way the Impreza uses it power as opposed to the Evo.

I've had Evo's and Impreza's of all ages, and that is what swings me back to the Impreza everytime.

andythejock01wrx

Have driven an Evo VIII. To be fair, with it's twin scroll turbo, it seemed plenty torquey and low down at that.

3k should get you there easily (torque wise) mine is 390 with only straight through exhaust, remap and airfilter but around 330 hp .... but every car is different!!

Burble wise the 2.5 is not as burbley???... as the 2.0 don't ask me why it's just not and that includes mine with a 4.5" pipe and no cats .... but it still fkin roars!!

Enjoy whatever you decide both nice cars ...

I have a stage 1 2.5 STI (exhaust and plugs) that is running 360/390. Like you I thought the Evo IX FQ360 must be quicker as it is lighter, but I proved myself wrong against a mates car. His was a standard FQ360 though. A few mods and it is a beast.

I personally prefer the looks of the Evo but the insurance and servicing costs put me off.

Both cracking cars, you can't go wrong. I think you will find a stage 1 2.5 STI is more than enough car for the road. If you want a track machine then Evo or more heavily modded 2.0 JDM STI.

Axe-Hammer

Thanks again guys, My heart is now fully Impreza devoted after talking to a few other guys today, although my choice of Impreza is not so clear cut, I'm going to save that for another thread!

andythejock01wrx

Hey Mikkel, tell us about your race with the 360!

Was there much difference? Could you simply be a better driver than your pal (no modesty now!! ).
