10 ways your Subaru EJ engine will BLOW UP 

🤣🤣 They have a sixth sense too 😉🤣

Definitely do 🤣

Absolutely 👍👌

Thanks mate. Number 10 is just so true 🙏

I have really been enjoying making them.. Love that you are enjoying them and finding useful 👌. Thank you for watching 🙏

Thank you very much 🤣🙏

That's very kind of you.. Thank you 🙏

Thank you so much Thomas 🙏

Thanks Chris.. Anything there that could have helped you? Or shall I do a special for you? 🤔🤣

@@racedynamix Ha ha, I knew about most of them except number 10 so busy saving a pot of money :-)

🙏👍

Thanks buddy 😁😁

Thank you Christopher. 🙏

@@racedynamix funny enough, my car has a sh!t map on it at the moment after a forged build. It has a fuel stubble at 1900rpm and cold start idle issue. Where the rev needle jumps up and down a little. Richard O'Donovan at Zen has looked at the map and isn't impressed, had det at 3/4 throttle and was running rich. So Rich pulled back timing so it was safe to drive home. It's booked in to see him this week, as he couldn't tweek it to make run any better, last week. He believes it could be a maf issue and is also attaching a sensor to my downpipe for proper A/F readings whilst mapping. He is having my car for a week testing everything. Any tips or advice from your experience would be greatly appreciated.

@@christopheredwards357 Richard is a great guy and I am sure will look after your car well. What yr/model is your car?

@@racedynamix 2018 Subaru WRX STI

Lol. Don't do that 👍

@@racedynamix can't see me ever selling it! Apart from running costs, it's the perfect car that does everything well.

@@FozzieSTIlife totally agree. They are going up in value too so a great investment too 😎

Yeah they are truly epic if looked after 😎

Thank you very much 🙏 Oil.. A good fully synthetic 10/40 or 10/50 👍 No plans for Norwich at the moment.. But possibly to around Cambridge soon 👍

@@racedynamix Cambridge would be perfect as well, will keep an eye on your calendar 😀

Lol.. Glad you liked it 😁👍🙏

Trying desperately hard not to say goodday.. Damn I failed 😁 Oil surge.. Unless you can fit a proper baffled sump (not the baffle plate) or dry sump then it is always a tightrope.. Slightly overfill the oil and check after each track session. If you can have a oil pressure gauge ideally mounted on window pillar so you can see it in your eye line around long corners.. I guess most tracks there are clockwise too. Lift if you start seeing it drop mid long corner. Fuel surge.. Solution is swirl pot and external pump. Aside from that keeping it above 1/2 tank solves it but the car is slower 😢 I hope you stick around.. I will be doing some track focused vids soon as my background of time attack taught me loads on that. (expensive lessons 😱)

@@racedynamix thanks for the swift reply! I'm sure the more stick around the more my questions will be answered, so I've got nothing to worry about 👍

Indeed 👍🙏

Subscribing to your channel very informative 👍

Would you recommend keeping my car 100 percent stock for reliability or do I need to do anything to my wrx sti 2015?

Can't go wrong with Deisel maps.. More boost, more fuel.. Done 🤣 Zero skill involved 👍

@@racedynamix and a James Bond style smoke screen lol

@@bunsofsteeeel 🤣

If the car is mapped for 99 and you run it on 99 then octane boosters is just a waste of money. Only exception being for a track day where a bit of extra safety isn't a bad thing 👍 imo of course

Absolutely 🤣👍

Why do you think it is crank case pressure? Have you ruled out compression issues or turbo?

@@racedynamix just fit a new vf43 as TD04 gave up the goose, so figured its blow by or oil getting pushed through to intake

It depends on the short block tbh.. Some of the closed deck classic engines need machining to accept the later stronger cranks. A spare engine is always a good thing then it doesn't matter what happens to the main engine 🤣 Its a good learning experience to put it together too 👍

@@racedynamix the spare i have is open deck, think im going to strip it down and may fork out to have it pinned or closed deck inserts when i have the block cleaned up, Current motor is using more oil than id like so be getting on with that sooner rather than later i think

@@traz1123 pinned would be my suggestion 👍

@@racedynamixcould you do a video on the different types of ej engine such as closed decked and open deck and what the advantages and disadvantages aswell as some block modifications you would recommend? Such as pinning and inserts

Hi. It's not something we get here in the UK tbh. It has some really good features but like all US software now it is limited by the green speed initiative to what can be disabled etc

Easy ... the same reasons I have had them for 23 yrs now. They get in your soul. No other car does. :)

​@@racedynamixmy BMW friends are trying to convince me to replace that soul 😢

@@zro.tolerance resist 😁

I also have a 2006 sti . Have to be on top with maintenance. Not like my 98 Honda prelude

Thanks.. I've only uploaded since the start of 2023 😁 and I'm the yoyrub8guy 😂😂

Hi Nick. The 17 plate is still a weak engine but if it were mine I would wait til it needs forging before doing it. The std engine should be able to cope with whatever the std turbo can produce. If you plan on changing the pistons at some point though it won't come as too much of a shock to you 👍

@racedynamix I don't want much out of it really, I've come to the age where I just want a clean car with a bit of power. 330-350 is plenty for road use. I do love a front mount tho so I'll probably will go for one, plus a intake then ill give you shout for a map. I just get nervous with the 2.5L. So expensive to forge it 😫

@@Nicks_Sti it can be but essentially it is just pistons that are needed so not that expensive in the grand scheme of things.

That's weird.. Is it showing empty on both sides of the dipstick? I have seen a big difference in levels on the twin scroll sump like yours.

@@racedynamix yesterday I drove to warm up and then let it sit for 5 minutes and both side of the dipstick showed empty. I let it sit for 7 hours and checked and both sides were still empty, so I added 1.5 quarts and it was between the low and high dots. I let it sit overnight and checked again this morning and it showed the same between low and high dots. I drove to work and it sat for 8 hours and I just checked and it's now above and over the high dot. I wiped the dipstick and reinserted and it's still above and over the high dot. We've owned dozens of cars over the years and never had issues reading a dipstick, so hard for this car.

Based in Bournemouth UK but travel to various dynos in the UK.. Mainly across the south 👍

Hi.. Thanks for the comment.. The manual is really useful and often ignored 👍 I'm not sure I agree re thicker oil, I find 15/50 to be the best for my race engines personally and that certain makes seemed to vanish.. Notably castrol Magnatec. But it is a largely superstitious subject and one that it is really hard to test in real world conditions so as to make recommendations to a wider audience... I will try though 👍

🤣 Just take it easy 😁😉

Yes they should. You can tell that just by the sound of the engine when turning it over. It kind of skips a beat on turnover.

@@racedynamix I know this is kind of imposeble to answer but the car had a vf34 turbo swap and replaced pistons and rods in 2018 in ones garage . Ben driving un tuned since. (Not by me) Watt do you think is damaged cylinder wall. Pistons or pistons rings. And depending the damage will it be worth working on ( believe it a 205 open deck) I have got another 205 “for now” a part of me wanted to rebuild upgrade and put the original in at some point . Even it is kind of silly if it is open deck..

@@tdro98 my guess would be ringlands had gone and the chunks of the ringland have scored the bores. Use a rebuild as a learning experience and it is worthwhile but it won't ever be a strong engine regardless of what trick bits you put in it tbh

I agree. I personally don't trust stealership anymore.

Lol yeah.. Too long 🤣

You know it 😂😂

It's true though for definite 🤣👍

@@racedynamix that's it I'm opening another savings account just to scare the EJ gremlins away 😂😂
