I'm sure this must have been asked a 1000 times already. But ho hum, what would an internet discussion board be without discussions?

Anyhow happy for someone to point me to a thread with the answers in it.


I've got a '99 UK spec Turbo 2000. I think officially rated at something like 215bhp.

I know Subaru UK offered the PPP kits which I think managed 237bhp and the JDM WRX's of the same period were rated at 280PS/276bhp. So I'm assuming that the gearbox, turbo and engine internals can at least handle a bit more.


So without wanting to go crazy with the cash or build a track day monster, what options are there for a bit more pep from a T2000? Links or specific info very welcome.

Thanks.

 

Best route for you.

Full stainless exhaust system using either a de-cat down pipe or sports cat downpipe.
HRC 255 fuel pump.
New panel filter, something like a cosworth or green.
3 port boost solenoid.
New plugs, ngkpfr7b
A fresh oil and filter change.
ECUtek remap by a reputable mapper.

Your car will make roughly 280bhp with similar torque and will feel completely transformed.
Most expensive part (and the most important) is the mapping, that alone is circa £550.
The fuel pump is just a safety measure and cost roughly £50. Second hand exhaust maybe £250, second hand boost solenoid roughly £20. Then panel filter at I'd guess £40.

 

Forged pistons were found in the STI. Also the Jap cars used different turbos, hence the ability to make more power.

 

Thanks. Anyone you can recommend for mapping? I'm in Bucks, but don't mind driving a little way.

 

Zen is in Northamptonshire

 

I would get a better top mount inter cooler too

 

Any you can suggest? I'm not up on Impreza tuning parts or firms, so any links to retailers of these bits would be most welcome.

 

Classic Sti one is a easy swap or if you got the know how a sti8 top mount

Few firms do alloy top mounts too

 

A Newage WRX IC secondhand is cheap easy fit. Fit a VF28/29 turbo and you'll get some good figures over the TD turbo thats fitted.

Beef up the clutch and fit some classic STi injectors.As its a 14 year old car things like the suspension, brakes, ARBs, bushes etc will be tired, so if you are upgrading power to get the full effect you need to be able to use it.

 

Whats your budget ?

Your intercooler and injectors are man enough to max out your current turbo.

 

classic on a td04 is gonna be more like 260 ish, may get a bit more, but 280 is on the higher side of results.

i pushed mine to 340, but not before blowing up the gearbox at 280ftlb and lots of supporting mods like oil cooler, aftermarket ecu, etc etc

 

What's the max anyone pushed a uk bottom end too ?

 

Modding a standard Turbo 2000 to 300bhp is going to cost quite a bit, and to be honest will only be as quick as a standard STi of the same year!! classic STi's can be had for very little money nowdays, would you rather save the money and put towards a STi, unless you are really attached to your turbo 2000.

If not then 300bhp shopping list below based on 2nd hand parts that Ive bought in the past etc:

Decat Downpipe £100-200
Exhaust system(full decat, midesction and backbox) £150-300
Ecutek remap £500
New intercooler (FMIC from e-bay £200) or 2nd hand newage WRX £50-£100
VF23 turbo from a classic STi £100-150
Uprated fuel pump £80-90 (new)

If your going for a FMIC the budget for a new induction kit for around £70-80 and aftermarket re-circ valve(dump valve) which can be anything upto £100

Looking min around a £1000 for 300bhp!!!

 

260bhp is right at the lower end, most make over 270 and ive even seen one break 290.
But, thats dyno figures for you. A car may make 260 at one place and then run 280 at another.
Most important thing is drivabilty and a well mapped 04 equipped car can be alot of fun for a newbie.

My advice would be to start off steady, a few tweaks and changes and see how you go. The list I put up is pretty much stage one mods, nice and basic, not too expensive and will really improve your car.

 

Haven't really got a budget in mind. It's just had a new clutch a month or so ago. But the bottom end has started knocking. So motor is coming out to fix/sort it out. I had been toying with selling it before the engine knocking. But if I'm going to spend to fix it, I might as well pep it up a bit as it'll have to be a keeper for a while at least to justify the cost. It's also far too tidy to scrap or break.

I know an STI would be a better platform to build off of. I looked at these a couple of years ago, but the money didn't work out for it. This T2000 turned up at a very good price from someone I know and has owned it for a good number of years. Suspension and brakes are all fine on it and its been mostly main dealer maintained.

 

What engine spec you going for ??

 

I don't think it's worth it.

By the time you've spent that money you could have a decent STI, for what it's going to cost to fix and mod yours.

Sometimes it's better not to get attached to these things, as they make no sense what so ever and throwing £3k plus at one is actually madness, especially when you can just flog yours as is for £500 and then throw £3.5k at an STI and end up in a much better place.

But it's your money so i'm happy.

 

Not really sure, want to wait and see what it looks like when we open it up. If I'm honest I'm not really wanting to drop a huge sum on it. I love the car, but it's primary purpose is a 4 door family car, I have other cars for going fast/being used just for fun.

Also I suspect in reality a '99 T2000 is really only worth £1500-2000 on a good day, and maybe only just over a grand on a bad day. And it's still depreciating.

I just can't justify spanking a huge sum of money on an engine rebuild. I did speak with a recommended Subaru engine rebuilder, but very quickly for even a standard spec we were talking well over £1000 for a rebuild. Sadly the car isn't worth it.


That said, I'm open to suggestions. If I'm going to commit to keeping the car for a while yet, I don't mind spending more on bits that are worthwhile. Are you able to recommend a spec to build the engine too and approx costings?

 

My suggestion is bin it, or if your good with the spanners bolt on a secondhand bottom end and sell it, you may get £500 more that way, but it's going to cost you at least £500 to do that, with engine and new gaskets and that's not fancy parts, or new belts and oil and water pumps,oil modine, oil, filters and coolant.

It all adds up buddy, i've rebuilt mine after the bottom end went, as cheaply as possible using a lot of secondhand parts, did the lot my self and it still cost me around £800 all in.

 

If you want to modify your classic turbo 2000 do it, but as stated its not cheap. My classic is running 300ish bhp with equal torque and it cost me over 4k not including the cost of the car when I bought it 7 years ago (people spend more again). But as has been mentioned in hindsight I would of hung on for a classic sti but I saw the standard turbo 2000 and fell in love with it. 300bhp in a road used classic is plenty enough and it feels rapid but like most I have decided to sell my classic (after I tidy her up a bit) and buy a newer wrx sti or wrx sti jdm and start all over again just can't decide what to buy? But it's whatever you fancy doing and most of the guys on here will advise you on what to do but don't rush into it ask any advice you want and most on here will give you a good response and plenty of help.
