hey am new to the forum. I currently have a celica gt4 (st205) with 320bhp. Im gonna get a new car next year and its between a few. Ive always wanted a scooby so id get the hawkeye or blobeye sti, preferably in white. I will only get a uk spec as i want the rumble. Now is it possible to get 400bhp without pushing the internals and whats involved in this? my other choice is an evo 8 and they can have 400bhp without pushing the internals, but id prefer a scooby. Mainly for the sound lol. Thanks for the info

 

HI mate, welcome!

newage sti engines are good for 450bhp

get yaself a turbo like an MD321T
walbro fuel pump
3"decatted exhaust
650cc injectors and a remap and you should be there but it is quite pricey

but before you do that, get your scooby decat it and get the fuel pump, give it a remao and enjoy, im sure that'll cure your needs for a while, 330ish bhp plus launch control = fun

 

weather it be uk or jdm you will get the same rumble with a big exhaust

 

i'll have to disagree with that, my brother has a nur spec on his jdm blob and it doesnot have a rumble, i can get a video up if you wish when i get home

it sounds like a motorbike

 

found this vid on my phone, this is only taking it to 6.5kish but you get the idea, even more motorbike sound at 8k.

ignore the begining..

it only lasts a few seconds - 7 -15secs or sumat

 

thanks for the info and the warm welcome. How much is quite pricey lol? if i was going to go for that 450bhpish? and is that all that would be needed what you stated before? no need for forging or anything else? thanks

 

Have a look at my Spec mate, click the link under my name. I'm running 430bhp and haven't forged the engine yet.

 

On a uk 06 onwards (hawkeye) your pushing the limits at 400bhp, and most would have updated and gone forged by then, the 2ltr is better for strenght out of the box for 400bhp.
As for the burble, if that is all your buying the car for, get a classic vw beetle, they burble far better than a scoob and it restricts you from the best cars out there which are twin scroll/equal length manifold
ALL uk turbo'd cars have unequal length manifolds, JDM's from the 2003 model year (STI's) are equal length.

Tony

 

Like Tony says, the hawkeye 2.5 engine could be fragile at that level. However, it has the added benefit of higher torque over the 2.0 litre and make a better road car.
Eggys' list of mods are spot on, but also consider an oil cooler and possibly an FMIC.

White cars are almost entirely JDM, so it'll be a 2.0 model that "shouldn't" need the internals upgraded.

 

as for price

650cc injectors.. millenium racer on here should be able tog et you them for 165

3" decat up to £140

3" cat back exhaust.. up to £350 for something like a nur spec

MD321T is about £1600 i think (over 400)
MD321H which is slight smaller £1200ish? (touching 400)

probs cheaper second hand if you can find one..

erm probs end up needing a clutch soon after that dpending how you drive, so allocate £500 ish for helix organis clutch or the like.

walbro fuel pump can be bought from harvey on here or lateral performance for £70ish pound

open source remap from racedynamix £350

you may need a 3 port boost solinoid so that can be up to another £80 but the mapper will tell you if its needed.

so as you can see the turbo is the pricey bit.. if its more of a track car then a road car , invest in a front mount too

there is a slightly cheaper route which i am going which is using the VF48 turbo from the hatchback STi.. that will get me between 380-400bhp

turbo cost me £280 which is a bargain

not many people ahve mapped them so not many are using this turbo yet..

but i think i'll be happy once it gets mapped at this power level.

note though this turbo is rare as rocking horse ****.. but cannon fodder on here as just sold his car and did have this turbo and supporting mods.. which he may be selling soon.. worth pming him?

hopefully find a car with basic mods done already i.e. pump 3" decatted exhaust and remap so at the 320ish level already..

and then al you relaly need is 650cc injectors and a turbo plus another remap which is what i will be doing at insurance renewal

then just wait for the clutch to go lol

 

Clutch wise......mine lasted a year at 430/375, and have just replaced it this week with a twin plate.

 

right thx for the info. I definetely wouldnt want to lose the rumble, can i get an uprated turbo that will give me 400+ and not lose the boxer rumble? or is that not possible? nd do the twinscroll turbos have a huge advantage or is it just slightly less lag? Does a single scroll/unequal headers have any advantages to equal/twinscroll? thanks for the info

 

i think that any scooby over 400 bhp on standard internals is only a matter of time before it goes bang how long tho would be anyones guess as some are luck and some are not, forged is safer plus lots of other things need to be looked at like clutch / gearbox and so on as standard will not last long

getting to 400 bhp is the easy part anything over that and its money and work

 

Tick,tick,tick,tick,tick . lol
D'oh!!!!

Eddy has it pretty much spot on in terms of the mods that would see you.
My clutch gave out at 411bhp / 375lbft.

TMIC can take 400+ but to be on the safe side I'd go FMIC to start with if I had to do it all over again.

Another word of advice.........Simtek & JollyGreenMonster!!!!


Steve

 

right id be happy at 400bhp that would be just what i wanted i wouldnt want to push the engine plus there wouldnt be much on the road that could keep up with a 400bhp scoob. So for this id need, decat, exhaust, bigger injectors, fuel pump, new turbo and a remap. Now can i keep the same unequal headers and get a turbo lyk the MD321H or something similair to get 400bhp so i can keep the rumble? thanks again

 

all as you said but with a md321h or a md321t and yes unequal headers

 

thanks alot mate good to know i can have tht amount of power and keep the rumble the same. much appreciated.

 

Most re-map'd diesels will give you a scare...

Even at 400 bhp.

Got to be honest agree with Dunx. A Passat by me has 270bhp & 430lbft ,even some of your hot hatches like the VXR Corsa can be mapped silly power. Take into account power to weight etc.

I had a Toyota Starlet scare moment in my scoob when I was running 330bhp . The Starlet had something silly like 260 or 280bhp. Big power in a tin can = BIG FUN.

Can't see why bother getting new injectors. Just add a FPR and make sure it's mapped safe.

Turbo wise, I'd go for the MD321-H for spool and power. It's rated to 400bhp but can make more.

The MD321T would be an over kill for your needs but depends if your thinking future proof in which case the T is great.
