pdeuce2985 haha I did have one of the best tuners tune it on the west coast. Also quality parts I would say and driving habits.

Blue STI absolutely man. Mine is stock with Cobb stage 1. For now....

Blue STI where did you get tuned at ? Yimi sport snail performance?

Snailperformance? Near Auburn

@@TheMrFlyBoy18 When you casually do pulls here n there, it'll last. Track it multiple days, boom.

Ya hes one of the best we have in Norcal

This car is blown up by now

Let me guess. Bains tuning?

FYI you dont need to drive like a jackass to blow a ej 257 Engine or Another of the other Subaru Engines either. Use google and se how many jackasses there are according to you. Wrx Engines are a whole other thing, they are reliable compared to STI´s.

Mattias Andersson trust me I see your side. I’ve worked with these cars daily for over 9 years. Maintenance and driving style play a huge roll in reliability. No matter if there bone stock or modified.

Mac Sti and I have owned one STI of each generation since 2002, and are now On my fifth. You have right, drivingstyle can make a huge difference in of the engine shall survive or not. But there are many cases there The ej 257 has broken, even without it has be driven bad. Both my Engines broken during the brake in time, With others words i drove carfully and followed the brake in procedure, but they broke anyway. One with ringland failure and one with a spun bearing. I got both times a New engine On The warranty without problem.. Subaru has kind of approved that they have Made a less reliable engine With The fact that they never refuse to get it on warranty.

Every engine blows bruh lol

Wrx are awesome to man. Good best to leave stock. Thanks for watching

@@BlueSTI No worries. I always watch. My 2017 base model i purchased in 2018 out here @irvine carfax out here in Ca. I hope the new,WRX and STI are good looking and fuel efficient. I hope subaru doesn't screw up the body style. Subies forever.

@@paulmarsdensr1095 ya I know man I'm hoping they're a good increase in power and look like the concept car

Subway Gaming Wouldnt need a fmic for that but it helps. Also ethanol blend if better for keeping knock down but please change the oil much more often than normal if rinning an ethanol blend. Lile every 2500 miles often lol

Sounds like a $10,000 investment

mosnin 7.62x54 thanks

@@BlueSTI can I get an update please?

@@bighitmayfield646 check out my newer videos for an update

I know plenty of 400+ who guys on stock blocks without any issues. its all in the tune and maintenance. all EJs don't blow up.

DeeJaySirWill Sure, but over time. Seals will leak, rings will wear, and you keep dumping all that boost into that motor which isnt designed to handle in stock form. Something WILL give. Nothing lasts forever. A built engine with the strongest pistons won't last forever. I work on jet engines. They don't last forever.

true but any EJ that is driven hard going at least 60k is a win Imo. lol

OCTurboJoe Some guys put a larger turbo on and run lower boost to make the same peak hp but higher in the rpm range for less time. The result is more reliability as the lower boost is easier on the pistons and moving the power curve higher up puts less strain on rotating components. Still wouldnt go over 340hp/tq on a stock Ej block lol. Just a waiting game at that point...

@@mrpsd590 Don't be That Guy. great nickname.

dragonlee1000 dam sorry. Sucks can happen anytime

rvidal0001 Sorry to hear that man... I miss the rumble from my boxer so much. I had a single exit titanium exhaust catless. It was awesome, but I plan on going iag stage 2 block next. Hopefully it will hold up better.

rvidal0001 Let me know how it works out for you. Are you on Mass Subaru or any other subie groups on Facebook?

rvidal0001 Ok man I will try to friend you. I subbed to your channel

@rvidal0001 hows it holding up?

I have a video of doing a drive by but with the EWG you don't hear the spool anymore lol cause it's so loud

Research bruh. Better to get as many things done as possible at one time to save money on labor and tuning.

Me, Myself & STI dont cheap out on fueling

Build the block first. Trust me. Yes you may get away with it, but in time it will fail. Bolt on’s is fine but make sure you find a quality shop. I recommend Metro Performance of SoCal. Over 30+ years of experience. Also, get on e85 with all of the supporting mods ASAP. It is less prone to pre ignition (knock). And if you plan to go over 350 to 375, build the block. 350 is pushing the stock turbo anyway so that will be your limiting factor. Another way to save money if you don’t plan on doing this work yourself, is to do it all at once. Most shops charge 1500 to 2500 to pull a block. So do it 1 time and get it all over with when you build it. Get away from uel header too. Yeah the rumble blah blah blah, but 1 you will get more top end gains and quicker turbo spool. And 2, with UEL header, the cylinder heads will be at different temps due to the shorter piping on one side. Not an immediate issue, but head gasket failure can result. Lastly, do your research. Find what parts are quality and other setups people are running. Forums are a great place as people have experienced things and can advise you.

aSUBIEnamedSTELLA thank you I appreciate the response! I am in south florida so I will look into reputable shops down here.

Me, Myself & STI you will most likely go to Rev Works.

I'm a real owner. Been like this for 51k miles 3 years

@@jandroredjunebrlue8574 no I have a Cobb fmic now. Way better than a tmic

Catless and no it won't pass

Never blew the motor but got bored with it and knowing a 13-15k motor build was needed soon wasn't something I wanted to do so I traded it in for a new Tacoma.

aSUBIEnamedSTELLA it's still the stock block. Ya I'd like to do the heads once I get it built

I need to do that to

It was doing great but I traded it in for a Tacoma

Dog dog true it’s just matter of time You must forge the motor to be reliable Why these guys don’t get it It’s hit and miss

Did you service it every 5000kms?

Ok well pay up then cause its almost at 60k miles now running awesome

@@BlueSTI do you have dyno numbers? I put 90k miles on my 2015 sti launch edition (flex) on a stock engine other then cat back and base ap tune. The first engine blew up (ringlands) at 50k the second engine messed up at 90k thought ringlands but it was a bent valve. so i bought a iag stage 3 short block. Its being put in right now. You should make a video on how you drive ur car and what oil and how often you change ur oil.

@@whocares5188 ya I have the dyno numbers. 413whp on 91 and 450whp on e85. Damn that sucks your motor blew up twice. Ya it sucks this happens to alot. It's my daily so I dont drive it like a race car but couple times a day i do WOT.

It's been like this for 52k miles on the stock motor. Lol I've had anxiety about it blowing up for 3 years lol. I been saving to get the motor built or just trade the car in all together actually

@@BlueSTI what car would you buy if you sell it?.

The intercooler doesn't make noise

Hunter S it's been like this for 48k Miles still running hella good. Ya I know its pushing my luck. I am saving to get it built

I own a 2017 WRX and was going to upgrade to an 2019 STI but after doing research on the EJ 25 I changed my mind. I still going to get rid of my WRX and go type R I don't want to rebuild and engine right after the warranty is out

@@PreparationdobleH Why would you have to rebuild the motor when warranty is out? That's the dumbest shit I've ever heard lol. Like as soon as the warranty is out the motor will need done lol, what

@@PreparationdobleH pretty sure the 2019 sti are getting stronger pistons from what I've read. You could also wait because the new sti could be getting the fa engine...either 2.0 with more output than the wrx or a 2.4.

Lol I got rid of it. I have the COBB FMIC now. Gained another 25 WHP just switching to a front mount over the grimspeed. The grimspeed intercooler still got heat soaked bad in the summer. I wish I went with a front mount in the first place

Its the aem one and the 3/8

At least 12k in performance mods not including a built motor. Luckily my motor has been ok stock so just performance mods with tunes and installs at leat 12-14k. Ya they get hot asf with a tmic when I ran the front mount the temps were alot lower. I'm sure also a better radiator would help. Ya I'm scared to man better to buy something that can handle the power I think.

Yeah the 8mm grimspeed ones

Yep

Check out my Instagram and I'll send you my dyno graph.

Full torque is at 4kish rpm

Now I'm making 413whp on 91 octane since I added a FMIC and equal length header

Way more than stock thats for sure!

You just have to take it off when you need to smog. put stock one on to pass smog then take it off and put on your downpipe. It's a hassel

@@BlueSTI did you have to do that with your iag aos also? i wish i would have gotten the cobb unit, they have a carb number.

I have a 17 sti. Just wondering if u still ran the stock block.

pabauza I run the stock block no issues so far but wouldn’t mind it

jonathan rodriguez snail performance. Travis is one of the best tuners we have on the west. He's in Auburn California.

Different heads though

No you need the support mods and a tune for that, upgraded fuel pump, injectors, fuel sensor, etc

Lol I had to Google that. 495 feet

Yep I'm way over on the limit

They already busted that myth. Watch the videos from IAG, the pistons and rings are still cheap.

@@colorado_koolaid2625 the RA block is the most reliable version of the Ej257 ever made from factory, aside from the S209 block. my 2020 sti is making 452whp on e77 at around 22 psi fp green turbo. stock block and transmission, stock clutch. obviously the clutch is a different story, but power-wise the block can take a beating, and i daily my sti. ive seen some guys running 500whp+ on their stock ra blocks reliably, granted that they dont beat on it 5 times a day. you just need go have the right supporting mods, reliable and good tune, and dont drive it like you stole it. i like the ra block opposed to any older ej257 blocks due to their thicker piston rings and hypereutectic pistons.

Yes still have it look at my more recent videos more performance parts been installed. Mileage sucks on a sti and even worse now. 10mpg on e85 and 14mpg on 91 octane

Good, sounds vise , i hope it last for you to, but unfortunetely i have some bad experience of the ej257. The ej 207 is much more reliable stock.I had own one of every generation of STI´s from 2002 , so i´m on my 4: th now. My STI is 2016 MY. The 2015+ STI are really handle much better than the older ones, and the steering feel is superior to the older ones. 600 whp would be cool, but i recomend you to get a frontmount ic then,othervise the performance gonna be quite short, if you push it it probbaly gonna get heatsoaked pretty fast, but i know you know that..:)

Mattias Andersson ya I been wanting to get a front mount now. Do you think I'd see some power gains from a fmic with my setup?

Yeah, i definitely do, and much more continiously Power , without heatsoak in lower speeds and stops in the traffic.The limit for a aftermarket top mount is about 450 whp i think, power over that you should have a frontmount...both for a gain in Power and much more temrature stable when you push it, without droping in the Power cause the IAT temp Rising....
