posted a link on Keiths' thread too, as said on there this flies in the face of everything I've read\experienced...although I have no idea if there is a difference between the wrx RA and wrx sti boxes, I assumed as they were both close ratio boxes they uprated variants...?
If you are will to loose the car as a road car, and have it as a dedicated track car, that is one way of keeping cost down imo, if you want to have a 10 sec road car, its gonna cost more cause you will need more power to move the weight..
Dedicated Track gc8 Type R
Strip it, and i mean strip it, everything must go. When your done stripping it then start cutting it, again if its not holding you the engine and box or wheels in place it needs to go
Ditch all the Glass, Fibre glass doors and Boot lid, bla bla bla...
Then if you can get down to 1000kg or bit less Do like Andy F and refuse to eat for 6 months... and you may sneak another few kg off, then probably 500-550hp could do a high 10 in the right hands.
2.1 or 2.35... gt30 or 35...syvecs, 5spd ppg etc etc cheapest way is lightness.. all imo of course

Be carefull drag racing can take over your life,
is it running 10s thats important or doing it in a scooby? and im talking as someone whos thrown away 40/50K on high hp scoobys, over a few years of madness,
if you dont beleive this stuff can addict you ask John Bradshaw he started out with a street skyline now has the fastest jap engined car in the country by miles, and a conciderrably smaller wallet,
The need for speed is a never ending quest, Drag racers are NEVER satisfied,
theres a standard joke in the pits, how do you make a small fortune out of drag racing??? Start with a big one..
that about sums it up.....
I personaly wiish id never gone to santa pod 20 yrs ago and i truly wish id never heard of the place..............

Yea i know the feeling sometimes i wish i never liked cars at all, and was just like the other guys that are happy and content in there mondeos or vectras etc etc. and loved jogging as a hobby or something...
There is no such thing as a target with cars, it always starts out as a target and ends up as a stepping stone..
Want 11, achieve it, want high 10s, achieve it and low 10s is only this or that away, acheve that and high 9s is only another few grand away..
I started with standard uk 97 turbo, and loved it, the v6 STI with ecutek and exhaust and loved it, then type r with 380, then type r with 420, then a 6spd was added, now i have a 2.35 motor sitting in a box that has cost more than a whole car, a build thats dragged over 2yrs now...never ending fookn story

I'm used to all this guys, i've been modding cars for years, just the wrong ones.
Running 10's isnt that important to me, this wasnt designed to be a project thread, just an advice thread about what people have done, what to avoid and the best/easiest way to achieve that benchmark "fast n furious" 10 second car.
My impreza is a toy, nothing more. I have another car for work so the impreza is purely for enjoyment. I've done the Nurburgring in it and will attend some meets like Japshow later this summer.
I know that the light at the end of the tunnel can never be reached. When I went to the Ring last year in my 200bhp Mazda my goal was a sub 10 min lap, which I failed to do as I spun it at 90mph and did a 10.15
This year in the Impreza I set myself the same goal but had only had the car a month so was still getting used to the (lack of) brakes and the crappy suspension set-up. I managed 1 dry lap all weekend, and did a 9m 29s. Now you'd think i'd be happy with that, erm nope! Was already sizing up brake upgrades, coilovers and weight reduction on the drive home, in search of a sub 9 next year. So the goalposts have moved once more, and I understand the work/costs etc involved.
As my car is a toy I can go whichever way I want with it, budget permitting. I dont have a huge disposable income, so I tend to do things slowly as time/funds allow, making slight improvement each time. Its a long journey, but fun, and thats what this is all about

if you want a road race or track day car, and for an occational blast up the track at santa pod then great, you have a car that will do that and if your conservative with your mods it wont cost an arm and leg
if however its the 1/4 mile thing and you realy secretly want to run 10s or even 11s then im affraid to say on this forum But as much as ill get ragged for saying it a scooby is a bad choice,
im talking here with some authourity about what scooby engines cost to get to the 600 hp mark and how long they last once you get them there (if their driven hard on a daily basis)
and as an FIA pro class racer and 20 year addict i know a thing or two about transmitions/chassis requirements for a quick car,
you can boast all the hp you want, without the right chasssis set up youll go nowhere,
just because they start life with more horsepower than most other cars you can buy for similar money, they cost a lot more to make powerfull and reliable,
scoobys handling is better suited to track work with a few tweaks.
ok good luck

Tbh you're right. A lot cheaper to mod an evo than a scoob. A lot. Plus they have the benefit of cast iron blocks.
Will never be as much fun though and they just dont handle like a scoob.
So pick your poison as it is going to cost you the same, whichever brand you pick

in fact id probably pick the scooby but if we are talking street legal fun cars with similar engines id take a cossie mk1 or 2 escort, with the right bits they can be killer on the dragstrip ( i know an escort shell is an arm and leg but the rest is prety painless i know a 600 hp scooby from zen or tracktive is 20K iv had them both) or the 6 pot toyotas making 1000 hp is relativly easy and the motor is real strong,
you can ultimatly do what you like and there are fast scoobys on the strip but they are usualy company project cars not for mere mortals,
Good luck with whatever you chose

How long will big end bearings last on this level? My engine needs a rebuild and I'm probably going for 500 bhp but don't have much confidence in these engines anymore and don't think it will be worth it in the end. My car is only a toy and don't see many miles but don't feel like changing big end bearings every year.

I had a standard newage sti engine with version 3 sti heads, run 523bhp for over 10k miles and still going strong when I stripped the car.

you could run a 10 on a standard newage sti engine in a classic with arround 450bhp
i got down to 11.06 1/4 mile last year in my full trim type r with standard newage sti engine, top mount intercooler, 6 speed gearbox sc42 twin scroll with 450bhp on e85

Bigarf's 650 bhp monster has run for 18 months without missing a beat. More than can be said of the clutch
When checked recently it made the same power now as it did on it's first full power map once run-in.

You might not be after that ("a lot of ££"), but that is what it takes and its almost impossible to get a reliable 10 second impreza. Eventually, pushing a car that hard something will go bang.
Dont jump into it just because you've had a nice weekend at TOTB and it looks like fun. Trust me, if you do you'll regret it.
Listen to people who have been there, seen it, done it. These cars are expensive and there is no way round it. If you take a month/two and have a look around, read up on these cars project threads, talk to people who know what it takes etc etc and still want to do it then go for it.
The fact you need to ask (And honestly, no disrespect intended) what it takes, to me means this is a bit of a knee jerk reaction to a great weekend, and we all understand that. Its probably what got a lot of us interested. Just some friendly advice mate.
Spec wise, Mikee is running a 2.1 stroker & billet GT30 and has managed 9.66 1/4. But he is an experienced pilot and the car itself has had some serious R&D done to it. It weighs less than 1000kg.
Many others are using 2.35's with various turbo's, billet 35 being a favourite. These are doing 9 and 10 second 1/4's.
Thats not to say it cant be done on a budget because it can but you need to understand that even on a tight budget you'll be looking at between £15k - £25k depending on spec. If you cant do the work/build of the car yourself you can add a lot more on top of that in labour.
Building a car like these is a lobour of love but they can also be a real PITA. Nothing fits as most parts are aftermarket/specialised. Everything needs brakets/supports/parts fabricating to make them fit. And so on and so forth.
Plenty of helpful people around that will be willing to have a natter so I'd take advantage of that before you jump in.
Good luck whatever you decide.

Wise words above, read and of the established project threads for an idea on whats actually involved in building a big bhp car.
