Jesse888 Forged/stroker turbo ek9


Update,
Running repairs and bucket seat install.
 
I've got some cheap stuff on the sump. Seems to do the trick ok.
 
Much awaited update on page 1.
3rd post shows the engine failure.

Now onto ring trip!
I'm sure you've all heard the news about the engine, well I'll start from the beginning of the trip and come to it.
Got to the ring with little fuss, first two laps where wet(first lap was torrential)
3rd lap(first dry lap) was great to feel the cars extra power and exploiting this power was fun to say the least. lap-time was only an 8:40 due to it being the first dry lap. Learning the new power, braking real early and coasting far too much where the reasons behind such a slow lap. I was also getting stuck between 3rd and 4th for a lot of the corners and not really sure which gear to be in, this would have been fixed with more laps/experience in the car.
4th lap,
Got caught into abit of a battle with 2 caterhams and an e46 m3. I let the caterhams through when I should have really just powered away from them and then the m3 caught us up on traffic so let him through. They then continued to get in the way the whole lap. Was massive fun though following them through the twisty sections.
This lap was 8:51, slowing down for caterhams to pass, then getting slowed down towards the end.
Video once it's uploaded!

Ok so lap number 5!
Was getting into it alittle more by now and was ready to start braking later and not coasting etc, came out of the cones to start the lap 2nd through to 5th gear full power down into the first corner around 110-115mph, check rear veiw for any faster cars jumping down the inside and just see blue smoke everywhere!
Yep disaster had struck! No warning, no odd noises or vibrations just blue smoke and a lose of power.
Managed to pull the car into the old pit exit and push it back up into the old pit section to get recovered. Opened the bonnet and oil is everywhere! At this time I'm thinking ****, must be a hole in the block or something. Turns out the turbo/pistons energy essentially pressurised the crank case and this spat oil out of the breather system and all over the underside of the bonnet/engine bay.


Adac then refused to bring the car back home on the grounds that they think it's only worth 800-1000euros. After along time telling the lady in the phone it's worth atleast 6k she just kept laughing at me and refusing to allow me to prove it to her. She then said that she refuses to discus the situation any further and put the phone down on me.

So if you've got Adac and your car is an ek9/dc2 or anything they aren't likely to know what it is don't bother with Adac.
Now this meant that I had to et the car home, so me and dad borrowed a trailer and headed back to collect the car from the hotel.

Still looks beasty even on a trailer!


Stripped the head off and was greeted with this.



Now, I'm sure a lot of you are dying to say "I told you so" about boosting a b16b for track work. But after afew pictures and a convo with romain he thinks I've had an injector failure more than the engine can't handle the boost.
The only cylinder with damage to it is cylinder 3, the others aren't damaged to this extent and there are zero signs of detonation on any cylinder.
So the feeling ATM is injector 3 either stopped firing or atleast stop flowing fully and this caused cylinder 3 to run lean and subsiquently run very hot.
The piston clearly expanded and started scraping the bore and obviously melted the piston.

That ain't bad, all you need is a re bore with oversized pistons and you'll be good to go again :nice: .
 
That's the idea mate, looking to out some forged pistons in and ask romain if he thinks I need anything else.
I don't want power(what I have is perfect) I just want reliability lap after lap.
 
You'll be needing custom pistons then if you want to keep it a b16b. The other option is the B18c route. I like the B16b personally.....
 
Yeah I'd like to keep it b16b if I can. But if the costs out way my preference then so be it.
Wouldn't a set of say forged b16a pistons work? Just lowering the compression slightly or am I missing something?
Take it they don't make a forged b16b piston? I haven't even looked into it properly yet but I have plenty of time before I actually start buying parts.
 
How about using a stock b18c4 for that power goal?
 
I want to keep a type r engine tbh. I don't like the c4 option and would rather rebuild my 16b.
 
The b18c4 seems to be a good engine to boost, seen quite a few builds using them.

Is one of the reasons why I don't want to use one, is alittle boring following the crowd don't you think?
Not saying a 16b has never been boosted before you just don't see it often.

I'm sure this engine would have lasted a decent while if it wasn't for the injector, pretty sure even a forged piston couldn't handle an injector failure for too long.
You can put the engines into "power goal" catagories but even the b16b can handle sustained 250hp as I proved at Bedford. The engine saw 137mph in 5th every lap and stayed strong at the ring until the above failure. Guess what I'm saying is I could have had a c4, this still would have happened.

damn man, I've only just seen this. Didn't realise until your post in another thread, forget to read page one on builds that update this way. Really feeling for you man, was only joking about first one to blow their engine you plonker! Whats the plan now? Least its not a complete failure, could of been a lot worse I guess.
 
Forged is the plan now mate, got plenty of options but looking like rods and pistons ATM.
 
I'll get them out today and take pics.

I wouldnt use B16a pistons as they'll lower the compression too much. Personally, I'd just use a set of YCP or Nippon cast pistons. They're stronger than OEM. It's up to you though...
