hey was flipping through the speed mag to see where they got it wrong with the new skyline and saw (to my amazement) that the new 2.5L boxer engine in the new wrx to come out in the next couple years or whenever claims to be able to acclelerate from 0-100km/h in 4.1 seconds and 0-160km/h in 10.4 seconds. CMON NOW, REALLLY!!! who are they taking on the ferrari enzo and mclaren F1. Now the they say the enzo goes from 0-100 in like 3.3 or 3.6 seconds or something and its powered by a bloody formula 1 stlye engine. So are subaru trying to say that with 0.5L more capacity, another 150nm of torgue or something that the thing can accelerate that fast??? I still think its :bs!: as i cant believe it until i see it i guess. AND who was driving it to get a claimed time like those? PLUS wat time will nissan claim with the new gtr as their new engine is like factory 470hp with 568nm of torque and wateva else, will it do 3second flat 0-100. CMON now really...

Tell me if there is any truth to this subaru claim and feel free to point out any errors i have made as i would like to hear any feedback from u guys

The 2.5 in THAT car sure as hell better be an all new motor as the USDM STi is already 2.5l and doesn't have a 0-100k figure like that?!?!?!

If anyone wants info on the 2.5L conversion, I suggest they read Fast Fours, join rexnet.com.au and speak to Damo who at last count, had imported 50+ 2.5L short motors from the USDM STi into Aus.

As far as i'm aware, the 2.5L in this UK sti is 1. More powerful and 2. based on the Spec-C. Which means that it is a LOT lighter then it's american counterpart. I believe most American magazines have got high 4's for their STI. Car and Driver magazine recorded a 4.6 and 13.2sec 1/4mile. Light car+powerful engine+AWD equals extremely quick 0-100km/h, but the top end of these cars aren't as great, same as 60-100km/h roll on acceleration etc.

if the article in Q is the UK tuner's STi Type 25, that is indeed based on a JDM STi Type-RA Spec-C (currently the quickest factory car in Japan, competition inc. Evos, GT-Rs, NSX-Rs, etc). Converted with the JDM 2.5 as mentioned above, would be an awesome combo. JDM and the rest of the world for now are sticking with the 2.0 boxer, which is a higher revving engine, feels more race-car like in my own opinion. The Type-25 has been reviewed by a few UK mags, very worthwhile read.

I know a GT-R with 1bar boost, full exhaust system and good tyres can do 0-100 in the low 4 second mark.

my friend got a 300kw@wheel R33 GTR

full house 2.7L tomei engine

STOCK turbo running 1.4 bar <- not blow YET

R compound tyre

and did 4 - low 4

The times could be right, but to be honest I don't know of any offical test times for the EJ25T. But do I know JDM EJ20T makes more power then the US EJ25T and the 2L still has plenty left too. Goes to show how far 2L turbo engines have come since.

The STI Spec C is no doubt a very quick car, about 2 version back now with the bug eye look...quicker due to weight reduction.

The STi S202 based on the Spec C is even more quicker with alittle more power and alittle lighter than the Spec C. Now this is a special car with only 400 built.

Also the UK Prodrive STi version isn't faster then the Evo FQ300 just yet, AUTOCAR did a massive speed and brake test late last year and the FQ300 was still a good second quicker down the quarter.

Not a very good scan but you can make out the 0-100mph-0 test times. The time break down are as follows: 0-60, 0-100 and 100-0. The FQ300 does well to clock a 4.42s (0-60mph) and a 11.99s (0-100mph); while the Prodrive STi clocks a 5.08s (0-60mph) and 13.17s (0-100mph). Both cars were tuned to 304ps or 300hp, thus the meaning of the FQ300 name. Though I still can't believe the FQ300 clocked such a quick times considering the JDM version does mid-low 13sec quarters and has more ponies...strange...must have been a very ideal day. Never doubt these cars they are now even quicker!!!

As far as i'm aware, the 2.5L in this UK sti is 1.

They might be quick to 100 but to only run a 13.2 over the 1/4 mile looks like subaru have worked to make the car get to 100 quick but after that its nothing special. No where near supercar territory there if it can only pull a 13.2 1/4.

I have and have watched the BMI with the spec C wrx and it is damn fast on the track but wouldnt be a good dailydriver with all the stuff they left out to make it lighter.

    • Oh dear. The panel beating needs to be done before the filler work. Do you have a photo of the dent before you started? Hard enough to not flex and only hit the high spots?  What do you mean it was just temporary? 
    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
