My ones a facelift jdm.Wrx Sti clutch kit through Wingers.The mufflers are for a bp model,so will probably just get the front pipe modded as its rubbing on a cross member and most of the weight of both mufflers is hanging on one rear exhaust mount causing vibration when on boost.Will do the mufflers at a later date when I do the tgv deletes.

Got all my parts together today for my Legacy,Sti clutch kit,front axles,suspension bushes,pitch rod and Sti quad outlet mufflers.

FlatironsTuning.All about heat wrap,ceramic coating and reflective heat tape.
I’ve used hpc coating on a Gc8 Rage steel exhaust system,downpipe,center and Sti muffler.Sold the Sti hpc coated muffler to a clubsub member.Used heat wrap on stainless downpipes.Never had after market headers.

In reality those are issues synonymous with almost all EJ engines regardless of size besides a select few.
Chances are the new 2.4 will share similar issue’s if it’s based on the FA20 the way the 2.5 was based on the EJ20.
They are considerably thicker walled which will help but the considerably longer stroke than the EJ’s means higher piston speeds which will again limit max rpm with the larger bore.
Then again, Subaru might have actually sorted their S*** out and bless us with a solid stock engine finally
Will have to see if Subaru rights all it’s wrongs with block,bore wall strength.Longer stroke says better torque.Smaller piston diameter then 2.5 says lighter piston with less inertia.Hopefully the Subaru R&D guys know what they are doing.

Yea nothing bolt on works but once going rotated there’s no extra hassle over a STI besides swapping out side feed rails.
Somewhat kicking myself for not doing the same. They’re not such bad engines once the stock pistons are replaced.
There’s a lot of problems with the 2.5 engines,bad heads,pistons and bore flex.Expensive to remedy with a flawed block,thin bore walls and big diameter pistons.The 2.5 engine was made popular in the US because they have rubbish gas and wanted decent power/torque outputs for bragging and moving there heavier late model cars.

Yea have seen that Welly one. Was tuned by Prestige. Was a bit of a major from the looks of things to pay for someone to guess their way through it from scratch. Super annoying the Haltech one only works for prefacelift, guess it’s down to them only bothering for Supergramps.
No harder than STI’s for turbo upgrades if going to a real sized one. Axles aren’t super weak. Heaps of people putting big power through them. Just can’t continually thrash on them and expect them to last. Shock loading them through S*** gear changes or launches are the only reason they’ll fail.
If putting a Sti turbo on a twin scroll legacy was that easy I’d have one sitting in my car now.Luxury of hindsight,I should have brought the US version with the 2.5 single scroll turbo,only I think the 2.5 engine is a dog.Subaru are bringing out a new 2.4 block (FA24 94mm bore x 86 mm stroke 2387 cc chain driven) which should remedy most of the 2.5 failings.

running with a tyre like the R888 will this allow me to be in the same class for superlap next year or is this when you have to step up to the big boy class (not ready for that) haha
You will trash a good set of road tyres on the track and trash a good set of track tyres on the road.The road tyres discussed eg. RE003 and PS4’s are mid range performance road tyres,made for everyday weather conditions,must have decent wear,ride well and be relatively quiet on our shitty NZ roads.I used cheap Yokahama’s (can’t remember which type,I sold a set 16” rays te37 mags with Yokohama tyres to ginganinga) as they did the job and I didn’t care if I wrecked them.
Would you play a game of rugby in dress shoes and go out to town in your rugby boots.

Then its not really a good test at all, I mean the RE003 and Pilot sports are prob the best-rated tires out there from the Hot Hatch guys. I can speak volumes for the PS3's they were amazing on the track.
Didn’t say it was a good test.Personally I don’t rate the RE003’s.I’ve owned a few sets of these on different Subaru’s.The PS2,3 and 4’s are way better.I’ve had all three models of the PS on different Subaru’s.Currently have the PS4’s on my Legacy and Outback.Swapped out the new PS3’s on my Legacy for the PS4’s.

Back on track for chucking a piggyback Link in. Up until now i’ve been jumping between a prefacelift 2.0gt manual and a facelift 2.5gt manual, neither are quite right but better than nothing at all to a point.
So, i’m wondering if someone has a JDM BL/BP facelift service manual or even a NZ new 2.0gt one?
Only really need it to confirm pin number associations as there is some difference in the one’s i’m currently using.
I’ve seen a facelift legacy with a piggyback link,Sti inlet manifold and fmic done by a company in Wellington. Haltech do a plug and play computer for the pre facelift legacy.I looked at doing this last year and most of the issues were canbus,the dash information,lack of easy turbo upgrades and weak axles/cv’s.As you know I’ve given up on modifying my facelift nz new jdm legacy for this reason.I’ll keep this car jdm with Sti mufflers,Arc tmic upgrade and a v7 Sti shortblock.
Except for the 89-02 legacy’s,the engines have always been a pain to modify.Years ago I did a motec single turbo conversion to a 94 RS.Thats one car I wish I had never sold.

Hi all,
I have had some quotes and the tyre shop has recommended for the track & street to provide good grip & wear I should go for the RE003's or Nitto Invo?
They both are the same price for a set also, there is some good feedback in here for the re003 however has anyone had experience with the Nito tyres?
Check out May issue ‘MOTOR’ car mag for 11 x tyre test.Includes Nitto Invo but no Bridgestone or Michelin’s.

Yea did read that.
Just the way they made the effort of saying each at the top makes it a bit less clear, like they are $250 each but must be purchased as a pair
Seems too cheap for 2 Brembo sized slotted and drilled rotors. Wouldn’t even get blanks from a reputable brand for that price.
I reckon they are as good as the znoelli discs that I have used on different Subaru’s over the years.
-
Yes,sold as pair’s.I replaced my Outback calipers with my calipers off my bl Legacy.I used Subtech’s Nakamoto discs and pads.Great combo for the money.Brembo conversion on the bl uses dba t3 alloy hats front and t2 rear,endless pads.wanted the t3 rears but they weren’t available at the time.I’d rate the dba t2 discs as average for the price.

I ran Falken FK 452s on my Legnum VR4. Were 19 inch wheels and tyres were 225/19/35. That combo with bilstein shocks was sheer brilliance. Handled like it was on rails. Did wear out pretty quick though. May have only got like 10k on em.
My version 8 STI came with re003s. They were a 215/17/45 if I remember correctly. Handling was amazing. Very very predictable and responsive. Had so much confidence driving with them on. Wheels were Westport forged 17s I think.
Then switched to Rota 18x9s on Michellin Pilot Sport 3s 225/18/40. I personally found that combo a bit weird. Couldn't really feel the road as well, wasn't as predictable and didn't have a lot of confidence at the limit.
The current 2011 STI has re003s in a 245/18/40 config (if I remember correctly). Feels great and predictable again.
Lots of options and opinions with this one aye! Going off my experience I'd recommend re003s. Thats just me though
Your ps3 225’s may have been a bit stretched on the 9” rims...

I’ve had Bridgestone re711’s on a gc8,can’t really comment on tyres I haven’t driven on.The s02’s were the old model.Replaced them with s03’s,didn’t like them.I looked at the ps4s,softer sidewalls,softer compound and way more expensive then the ps4.

A front pair of Bridgestone RE002’s and 003’s would last me just over 10,000-12,000 K’s.The last decent road tyres Bridgestone made were the so2’s.Changed to Michelin pilot sport 2,3 and 4’s.Way better k’s out of the Michelin’s,quieter,better grip,turn in and great in the wet.Had a new set of 3’s on my Legacy,as soon as the 4’s arrived I swapped them out.The first shipment of pilot sport 4’s were a softer compound and had less writing on the sidewalls.The NZ tyres have a harder rubber compound.I have the 4’s also on my Outback.

Shout out to Gareth and the guys at Subtech.Picked up my Outback 3.0R with the calipers off my bl b spec fitted.Used there new range of discs and ceramic pads.First impressions are good.I’ve used Znoelli for over 10 years and Mintex.Using Dba and Endless on the bl.

Using it initially with the factory twin scroll vf45.
-
Anyone here installed a Process West tmic to a twin scroll 2.0L?
-
PBMS 19.8 psi 715nm
TT 18.0 psi 385 nm
Car went onto PBMS Dyno three times for reflash after car lost tune.No knocking,or fault codes.TT found the passenger side exhaust avcs was playing up.The winding in the oil solenoid valve motor had a break.
Regarding boost and power output,car runs turbo back 2.5” decat exhaust with factory mufflers.Possibly shows how inefficient the factory tmic is.
-
No leak,just a small turbo running out of puff.Yeah,the efr turbos are nice.Was looking at the 6258 twin scroll,vf36 on steroids.Spoke to a guy in the States,mentioned that if you don’t like turbo whine this is not the turbo for you.

Custom up-pipe/downpipe or are you just going to change to STI headers?
If you're going the custom option, seems like a shitload of $ to spend to make 200kw.
I’ll use my factory headers.200-210 kw atw and max torque kicking in just after 3000-3500 rpm makes for a great practical road car.Vf45 is pretty much maxed out at 18 psi,full boost starts at 2800 rpm and stays flat to 5200 rpm and tapers off. Has been tuned running 19.8 psi,torque comes in harder but boost tapers off earlier.Computer would not hold tune.My thoughts are that the vf45 turbo is working outside it’s efficiency range above 18 psi,9.5 compression and tmic.Power for both tunes 185 kw atw on different dyno’s.
Don’t forget the Legacy short block starts to get unreliable at 200 kw atw and the heads run out of flow at 240-250 kw atw.

I was told that the flywheel and pressure plate was the same size for 230 or 240mm clutch plate and that the 230mm plate was used in the Legacy to allow more clutch slip for the heavier car and driver.
