SUBARU-STI-2005

Has any new age sti 2003 to 2005 gone pop? How often or is that a rare issue

I've had 5 Imprezas ( one API 330 classic and 4 new age inc a 400 bhp bug sti ) and have had 4 evo's ( 2 x 8 MR's and 2 FQ IX's, all tuned to 400 / 400 ).

I love both Marques to be honest, the Later evo's don't need a lot of money spending on them to get 400 and make fantastically quick A to B cars running that much power.

My bug sti needed a lot more money spending on it to get the same power, but the delivery was completely different, mainly due to the Aps sr40 which was laggy low down it when it came on boost it used to feel incredible. This was 7/8 years ago when 400 bhp wasn't so common as it is now.

I bought my 2nd to last IX of Dr John Banks and the way he had set it up was incredible. It used to come on boost so early that it almost felt naturally aspirated, no discernable lag whatsoever, a tribute to Mivec & Johns mapping.

I prefer the handling on a Evo 8/9 but the Imprezas have the better 6 speed box and I'll always love the flat four noise, and with equal length headers the noise my sti used to make was phenomenal.

I would happily have a well sorted spec c or jdm sti as my next car when I return to the Uk, but would just as happily have a well sorted IX.

Hi rajaman thanks for the feedback so it seems like the evo 9 comes on boost earlier and delivers the power in a smooother way handleing better as oppose to the subaru which will deliver in a more raw powerfull way and boost a bit later better sound and with less better handleing?

Is there much difference in boost times then? Where does an Evo 7/8/9 hit full boost?

I can't see it being that much quicker than a jdm TS version surely? I've had a play with a couple of evo's and ain't come across one that's had the upper hand yet

On another note my buddy bought an Evo 4 last night, I honestly thought it was broke when I got in it don't get me wrong it goes well enough but the feel of the car don't equate to what the clock is showing you if you follow my drift its running standard boost but honestly didn't impress me, no way on earth could I go back to .7 bar of boost or what ever it is

Evo 4s are very fragile. If its a standard Evo 4 engine then they don't like a lot of boost. Much more than 1 bar he might be saying hello to a rod. And they suffer from crank walk.

Kezzo80

My Evo 8 hit full boost circa 3500 IIRC. My Evo 9 slightly earlier with the Mivec.

Yea done a bit of research in to the Evo 4, had a good look around it, tried checking for float on the crank by hand it felt sturdy, he's not planning on running massive boost but yea ur right they are fragile lol, my other mates spat a rod as soon as he turned the boost up, he's well aware of what can happen if he pushes too far

And my jdm hits 2bar of boost by 3300rpm so not alot in it then, and that's on a lm450, so if it was a smaller turbo it be quicker again, I personally don't think there is a great deal between the 2 IMHO

RA Dunk

That's quite impressive for a 450 capable turbo..

In all fairness to it bud it does rev well, If I decide to get an engine built then im seriously debating a 2.5 bottom end with a LM500 standard position turbo rather than having the extra cost of rotating etc, looking at how well mine performs and comes on to boost I'm guessing with that setup and a little head work done its going to achieve 500+ with good low down spool from the extra punch the 2.5 offers, the only thing that I keep coming back to is running a 2.5 bottom end at that power level, yes it can be done but its costly, so do I go the tried and tested 2.1 route, I would be buying all the parts bit by bit to fund it anyway ideally I would like to go 2.5 but its all going to boil down to cost and the reliability l will have given my funds, but I bet it would go rather well done right

So what can a later Evo engine take on standard internals? Are they as robust as the newage motors in the scoobs?

Also want to know this

2bar on an OEM Scoob engine and a GT30 type turbo..... you like living close to the edge!?

It's been dialled down Shaun after listening to yourself and Mr Rawle, I knew myself it was probably a tad high it at 1.8bar and tails off to 1.6, was certainly entertaining at 2 bar tho

Comparing those two models (both are practical, cheap to run, have excellent steering/brakes/chassis/diffs/suspension out the box), there is very little in it except the following IMHO:

Subaru 6 speed is stronger than the Evo 6 speed, but the 2005 UK STi has horrible gear ratios. Evo 5 speed (look at the 9GT) is strong, but is short geared for a car you'd use to cruise at speed. Replacing my Evo 6 speed was much cheaper than replacing or repairing my Subaru 6 speed.

Evo more expensive to buy, but much cheaper to tune to 400 BHP and has a much better power band. Single scroll 2 litre Subaru engines spool the same turbos so much later than in line fours, it is just a bad design and I would never own another as a performance proposition. Moving to Evo engines afterwards was a revelation for me. They tune so easily and are so knock resistant, the 4G63 is an absolute god of an engine except for its sound. The only thing good about a single scroll EJ207 is the sound.

My Evo 6 only Stage 1 mods, Fuel Pump, Full 3" Exhaust, Apexi Induction kit,AVCR Boost Controller, Mapped by RC Developments + Greddy Intercooler.

That would sometimes hit 1.84 boost on a cold night but the high limit was 1.7.
standard turbo and injectors. Biggest difference was the weight of the cars.

I also had exeddy twin plate clutch which allowed the power down better.

The cars are very much the same, They were bread to rally and in the same era really.

The new Evo's are heavy and new age Scoobys heavy, and both will upgrade to stage 1 at about the same power.

Honestly people there is nothing between em, Scooby feels better at handling but Evo feels a little more responsive on boost!

Love em both but if I had the coice and could afford it. Bayside Blue R34 GTR all the way!

My Evo IX that Rajaman bought (nice to hear from you Ray!) spooled to 1.7 bar at 2500 RPM. It held that boost to 6000 RPM. Absolutely incredible engine. I treated it like I did my Subaru engines, it held together and made power everywhere. The Subaru engines did neither.

That's pretty dam good John, impressive stuff, what turbo do they run on the 9? What was done to the car and what power can the stock turbo cope with comfy?

Is it simply the usual mods i.e exhaust, map filter to reach the 400 marker? I gather it is which is where the savings take place over the scoob, as your in to turbo, injector, fmic (possibly, where as they come standard on the Evo) pump etc so can see where the savings come in to play, but that said its mainly a turbo swap on the newage Sti to reach the realms off 400 give or take, the tmic works pretty well up to there from what I can see, injectors are there or there abouts, but then again a decent turbo second hand to get to 400 is a fair old wedge

Kezzo80

The IXs run a TD05 16G. I don't know a great deal about them other than they were ubiquitously known as the 80series! They are cracking little turbos that could easily do 420 hp with supporting mods. Not bad for a standard Mitsu turbo.

Kezzo80

Exhaust, filter, 3 port solenoid, 255 fuel pump n decent remap was all that was needed for close to 400 hp and maxed 560 injectors!

Mine made 390 at stage 1 mapped by Andy Fox.

being an ex evo owner i can tell you both cars are very good its down to personal preference, the evo doesnt seem to have the disease of lexarse lights and stickers so in my opinion has a far better image.

both great cars and as an mlr member i have posted

Very similar cars as has already been mentioned, and no, they don't drive themselves as many Subaru owners love to mention. Try lifting off when the AYC is doing its thing and see what happens

I loved my EVO and regret selling it, so much so I'm on the hunt for another as we speak..

john banks

As Kezzo80 says really. Mine had full 3" exhaust, fuel pump, AVC-R, remap, airbox lid mod and I hit the fuel pressure regulator with a hammer to get another 0.5 bar fuel pressure to give me a bit more headroom on the injectors. It isn't just the cost of the turbo to get 400 BHP that concerns me, it is the responsiveness, even when you stir the gearbox. Compare a 400 BHP Evo in 2nd gear at 3000-3500 RPM with a Subaru of similar power and you'll see what I mean. Are you really going to change down to 1st?

+1 on lifting off whilst ayc is doing what it does! Would shock a few no doubt. Which Evo you looking for? I've had my 7 since just before Christmas now and I love it

Kezzo80

I miss my Evo 9, but I really am looking forward to buying an Impreza

I missed out on a nice Reims Blue V1 which was advertised on MLR only last week, I didn't have the time to travel to Leeds to view it....I'm looking for V1, V11 or an V111, depending on spec

Cool, I wanted an 8mr originally but when I went to view this one less than 5 minutes from my house it was so clean and has extensive history for a price I couldn't turn down. There's days where I think I should have held out for an 8 but then think how rare the 7's are and remind myself how good a car I've got lol

Just been following a similar post on MLR, seems Imprezas are a load of common rubbish and not to be tolerated at any price! I quite liked mine till I read this
