This is the first of the upgrade path videos that I will be doing. Trying to stop you spending money on things that are either not needed or total garbage.

[@Crimsonxdecay]

Thank you for making this video. I've been trying to upgrade my 05 wrx to get over 300hp. Just couldn't ever find a proper list of upgrades in the way that you did. subbed.

[@racedynamix]

Cool.. My pleasure. Let me know if need any help 👍

[@Crimsonxdecay]

@@racedynamix Thank you, I certainly will brother.

[@Sean-f1j3k]

I had a 2005 wrx 300 was told it had 260 bhp. In my humble opinion it felt like enough power for the clutch, breaks, suspension. Great car loved it.

[@racedynamix]

Yeah balance is key 😎

[@DevinBenson-h5t]

Awesome video! I have to pull my motor for head gaskets in my 04 wrx and I will also be doing these mods along with the Grimmspeed intake and catless up-pipe

[@racedynamix]

👍. Thank you 🙏

[@gabrielttenroc2906]

I’m excited to see what my bugeye makes! Mod list: Billet 16g 1000cc injectors 340lph fuel pump Mac 3port APS 70mm cast air intake AP Cast 3in turbo inlet Sti intercooler 3in exhaust Stock manifold WORX bov 2 core radiator 38mm ewg E-Tune

[@racedynamix]

All depends on the quality of the turbo and the e tune. Billetb16g is normally 350bhp tops. Don't know why you would put 1000cc injectors in there though... 550cc sti pinks would be plenty

[@brasher12a]

Good content, I think a lot of tuners concentrate on the final HP figure and dyno graph but can fail at the setup part of the tune that covers 98% of driving, MAF and Injector scaling are often barely touched, relying on closed loop control to do the grunt work. This leaves a car that drives rubbish at low speeds and can cause unnecessary stress on the engine. You would be amazed the amount of "tunes" with an intake that still have MAF scaling left completely alone. I'd love to see more videos of the philosophy between AFR targets and ignition timing. We have a slightly different tuning philosophy here in Australia with our fuel and more climate (ie HOT!) so it's not unusual to tune around 11.5-6 AFR but timing is less aggressive. Keep up the good videos!

[@racedynamix]

Thanks a lot and a big hello to Oz. There is always that 3 way tug of war between boost, fueling and ignition.. I will see whether I can pull a video idea together for it to demonstrate the different ways to get to potentially the same end result. I have seen a multitude of shocking 'maps' too. 😂

[@MrGreenperil]

Great result and exactly what we got on the red scoob you mapped with the same mods.👍

[@racedynamix]

😁 Cool

[@MrGreenperil]

And my I add still going strong Duncan 👌

[@WRXkas]

This is exactly how I have my wrx 05 wagon rigged... With vf35 we made 320. - Stock clutch is enough so it dosn't put too much strian on the 5sp - 5sp clutch plates by kien, to help strengthen the gearbox (im still debating whether it has helped but I believe so). - colder sparkplugs - Koyorad radiator, keeps coolant temps down better than stock rad. - Godspeed J discs & pads - whiteline swaybars & endlinks These are the other extras I would recommend and made a big difference all round.. since the upgrades iv put on 35000 miles with some trackdays. But maintenance has had to be more frequent.

[@racedynamix]

Nice set up 😎

[@rev-you1975]

Excellent. Great video. Forester Sg9 next please. Much appreciated.

[@racedynamix]

My test mule is an SG9 sti.. But will be doing an XT very soon 👍

[@TheRZBM]

Glad to see you pop up on KZbin, always hear your name on the forums and Facebook groups. I've got a V9 JDM STI and always wondered about remapping options. Had it a few years and still running stock tune and Shell 99. I don't care about power numbers just want it safe and reliable. Is it worth remapping? Some say they are fine on stock tune as long as on good fuel whereas others say it should be remapped for UK fuel but then they always seem to get a bump in power over 300hp which I am not fussed about if it might harm reliability. Cheers!

[@racedynamix]

Thanks mate. If it is reliability then I could give it a check up and amend if risky.. Or push it higher without affecting reliability as would be custom tuned for UK fuel rather than hoping its OK 👍 fb message me or text 👍

[@johnorr2241]

How safe would this engine be after these mods and this much power, provided it was driven carefully and not abused?

[@racedynamix]

No reason why it won't live that way for many years like lots of these that I have done to this level over the past 17 yrs 😎

[@LTgytis]

Hello, I'm glad You shared a video of the technical part! I have a question: What ignition timing You are getting at MBT and what fuel you used?

[@racedynamix]

Hi.. I go into much more detail on the stage 1 remap video but if you want LOTS more detail then join in the Academy and all the info is in there plus extra live streams, videos and discord group 👍

[@Mr_Jingles_147]

Would be good to explain that "lean" bit some more. Loads of people adding air related mods, decat, fmic, induction kit etc with zero fuel compensation or mapping that claim the magical 300 brake bruv innit, when we both know its more like 180-200bhp and playing the det can symphony of tinnitus!

[@racedynamix]

All coming Stu🙏 A special '10 reasons why your engine will blow up' video coming soon 🤣

[@Jjm2024-u3t]

Do you not have to go down the route of forging, for a bigger turbo on these?

[@racedynamix]

Not really..depends on how big a turbo you want to fit. The std engine will cope with 350bhp normally. Some customers are running std engine over 400bhp

[@jchalmers28jc18]

Where you based about add like your to check mines and adjust if needed. Ave got all the mods you said and big brembo breaks . Been told 320bhp feels fast but really fuel smelly maybe running rich

[@javieraguilar1615]

Great video thank you. Question, is this on a stock clutch n flywheel? Or wat would u recommend for that set up?

[@racedynamix]

Yes, this was on the std clutch and flywheel. If in good condition they will cope with the power. If they didn't then an exrdy organic would be a good shout 👍

[@johncole5203]

Hi Duncan. If you were running a front mount set up instead would you still target low 11's for afr or go mid to high 10's afr?

[@racedynamix]

Hi. Thanks. The fmic would allow me to run it marginally leaner if anything as the air charge would be colder and it would also mean more ignition timing could be added. But there are many ways to make power and on the dyno it is so much easier to see what actually works.

[@johncole5203]

Thank you for the reply Duncan. I look forward to seeing more of your videos.

Hi, I have a sf5 stb sti forester. 2001, it is an auto currently but I'm going to do the manual swap 5 speed swap. The link g4 is an option for me as I would love to tune it. My Mod wish list so far, Turbo back exhaust decat. Performance fuel pump Vf28 hybrid or vf34 hybrid whichever I can find. Spec c sti intercooler Pink injectors Aet water meth kit Fuji parallel fuel rail kit with regulator. Cylinder 4 cooling mod. Link g4 + ecu Every single suspension component will be upgraded, brakes done and tyres also My main aim is useable power to have fun in, quick spool maybe around 350ish. I am more than willing to pay the appropriate freight, is there any mods you'd recommend that would benefit the car? Thank you

[@Jonny5ox]

@@racedynamix I'm based near colchester, essex. I'm looking to get lots of parts together and build it, I've spent alot of time researching parts that would benefit the car and once everything's fitted, I was hoping I could get you to tune it if possible. Would those particular mods be a good option in your view? I would like to drive it for a bit as an auto before manual swap, if I put turbo on and few other mods to compliment that could my car be re flashed and tuned by yourself on the stock ecu with the auto box on car? I would then do link g4 or similar with manual conversion and tuned with you again

[@marcospanoyannis8875]

Hi ,also have a 2005 wrx and thinking of doing the same mods ,would the stock clutch and gearbox handle this power

[@racedynamix]

It should assuming they are in good condition. :)

[@kingkobra247]

What sort of power would you get with all these same mods to a 2.0 wrx but without the sti turbo? I've heard the TD04 stock turbos can take 300hp. is it possible?

[@racedynamix]

Hi. normally they do around 290 but on rare occasions I have seen over 300Bhp but it is rare

[@kingkobra247]

Is it safe at 290? Or would the turbo be likely to blow out at that power level. Thnx.

Hi 2002 wrx srock engine 218 .stock fuel systems . Sport cat vf34 turbo . What is realistic... 250-60? Or do I abselotly teed a better fuel system with a vf34.

[@racedynamix]

Hi. The std injectors will flow enough for around 310bhp assuming you fuel pump is good and working and run on good quality fuel. What octane/ron fuel do you have available? 260 seems very low.. Even with 93 octane fuel I would expect closer to 300 without injector change.

[@tdro98]

@@racedynamix Thanks I didn't know what to aim for , I have taken over a project from someone else and don't have the finances to upgrade the fuel system yet... Will the original engine Hold anything more than 7000 rpm? And would there be any point with a vf34 In terms of boost pressure, if the engine could Handle it

[@racedynamix]

@@tdro98 peak power would be around 6200 so no point revving beyond 6800 which is the std rev limit even if the engine was strong enough to cope with it.. (which it isn't) Just needs setting up nicely and will be good

Out of interest what power could you push the standard turbo to with the other 5 mods you mentioned?

I will be doing that exact thing in a video very soon... You wouldn't need to upgrade the injectors and the intercooler upgrade wouldn't be absolutely needed.. Not wanting to reveal the punchline from the video but 280-300 is normal
