Guess this is now a 'build/project' rather than my ride.

For those of you that haven't seen it, here's my car.

I've used this car as my daily hack for almost three years now, with weekend autotest events with the local car club and the occasional track day, and recently tried my hand at sprinting.

The car was brilliant, never let me down no matter how much **** I threw at it, and I loved it. My friends sometimes commented that I was 'long overdue a breakdown' without the amount of abuse it simply lapped up. Well sadly that day came in mid Novemeber last year, where in my early morning daze on the wa to work I mistook my car for a yacht and drove it straight into a flood, which promptly shot straight up my crappy AEM intake and filled cylinders 1 and 4 with water and hydrolocked the engine.

After having it towed out of the water I removed the plugs, pumped the water out and tried to restart it, only to find that it span over the same whether the plugs were in or not. Sounded like a major loss of compression...

Straight on EK9.org, found a B16B for sale with a good rebuilt spec at a good price from J700OCK and promptly purchased it after a brief chat with John and Will at RDT to confirm the rebuild. Week or so later the engine arrives in a bulletproof package at the local garage, mechanic makes lots of rude noises about just how well John and packed it. He did tell me to check it out, I was impressed. :clap:

Left at the garage for a week or so, by this point the temperatures are down below zero and my choice not to attempt to swap the engine on my parents driveway (with half my toolkit lost to the ether) is paying massive dividends. Get a call to say the swap is complete after sourcing a stock OBD2a EK9 ECU to run the engine along with a new OEM EK9 friction plate and energy suspension poly engine mount inserts. Pick the keys up on my way home from work and run the car up and down the road to check it runs properly. It runs sweet, really really sweet. The mechinc commented how suprised he was when it fired up on the first turn of the crank, guess these sort of jobs are usually riddled with problems.

I drive home and return later to pick up the car. Warm it up and take it for its first drive, once it is warmed up I give it a proper push up through the revs, there's no difference from the B16A until 6200rpm, then it all goes a bit batshit and the thing pulls like crazy until it slams into the limiter, begging to go further. Liking this then... Annoyingly I only get that one thrash in and it starts snowing. No bother, only a few flakes and it's the Isle of Wight, it doesn't snow here. Wrong, it snowed, properly, whilst I'm out on my maiden voyage in the middle of nowhere. Luckily, although grip is low she's perfectly controllable, the Spoons are lapping up the uneven surfaces with ease. Ease the car home, a few corners from home I see the brand new Citreon C3 understeer off the road into a wall. ****, nothing I can do I'm already commited to the corner by this point, so I stupidly pull the handbrake and the car executes a massive broadside drift into the corner, plant the throttle and it pulls round clearing the striken Citreon by a few feet as the driver looks on in annoyance. That was ****ing lucky! :shocked:

Anyway, new engine is settled in and all is good for a few months. The car club is in it's off season for tarmac events so I don't get to try out the new engine until about Feburary. First event comes round and the car feels good, absolutely rips in the top of the rev range and managing to hold some decent times down. Only when someone comes over and asks me if I have shares in Castrol do I twig something is wrong. Apparently it is smoking, really heavily on the throttle, thick blue smoke. Sure enough I do another run and check the RVM to see a cloud of blue behind me.

Cut the day short on seeing this and limped the car home suspected knackered piston rings. A compression test shows all cylinders producing 200psi, which kind of rules out the piston rings. I learn that a blocked PCV could cause the same issues, so pull it out, clean it out with carb cleaner and the problem appears to go away. All fine for a few months more...

Roll on 10th April, IOWCC gets invited by FDMC to the Dimanche Sprint at Farnborough's Rushmoor Arena. Despite a regular attendance of 50-60 cars at IOWCC events, there were only four takers for Dimanche, most likely due to the costs of getting a license, the safety kit you need and the costs of travelling to the mainland for essentiall 6 minutes of driving. None the less, four 'visionaries' from IOWCC sign up, a Mk1 Escort RS2000 rally car, a VX220, an MX5 and myself.

We make good time up from the 5am boat to Rushmoor, (with me finding out my car does infact have a JDM 112 mph limiter still in place, much to my annoyance) and get signed on and scrutineered and set out the deckchairs overlooking the arena. Unlike IOWCC events, every driver was given a number had had to run as close as possible to order, so we await out turns and head out. I've swapped some A048s onto the front wheels for this, putting the AD08s on the rear and softening up the rear bar to try and compensate for the increased oversteer.

The practice runs are good, I'm missing apexes all over the shop having never run the course before, but still managing to put in fast times within class, and managing to beat the VX220 is the bain of my life at IOWCC events. Feeling pretty good about how the day would I go I head out for the first timed run, and screw up a corner exit losing me about half a second. Never mind, three more to nail it in. Start up the car for the second timed run, and as I reverse it out of our makeshift paddock, there it is, the death rattle. It's silent at idle, runs as sweet as it ever has, but hit 2k rpm and the bottom end knocks like a skeleton having a wank in a biscuit tin. Game over.

Here she is on her last run:

Get the car towed out of the event and down the road about 2 miles, borrowed an AA card and pretended to be my mate and arranged recovery. When the bloke arrived, obviously asked what I was doing up on the mainland from the IOW, I nonchalantly say I am up visting friends for the weekend and the engine has packed up. He starts hooking up the car to the dolly to tow me home, and all is going well until he asks me to open the boot so he can hand the tailer lights and numberplate. Open the hatch to reveal a boot full of racing tyres, jacks, tools, oils and a helmet. Busted!

Luckily, the guy just laughs, he knows full well what I've been up to but reassures me that it's OK, the AA recover from trackdays. Really I think he just wanted to come to IOW...:naughty:

Caar goes back to the garage that fitted the block for diagnosis, few hours later and sure enough, some knackered bearing shells are removed. Luckily the failure was caught very early and there is no damage to anything, some new shells should sort it. Considering the car burnt a litre of oil in the drive up to and including three runs at the sprint, I am fairly sure the rings need replacing, unfortunately this bumps the cost of the rebuild right up, and with an imminent house move on the cards I arrange to have the car stored at a mates barn out in the coutryside.
 
So, history of the skip out of the way, roll on two months to this weekend. Settled in the new pad which luckily has a large driveway and a garage, so I'm all set for a DIY rebuild this time.

I'm pretty crap at taking pictures as I am working, so these will be sparse but I'll remember to take some when I can.

So, job started.

Tomorrow I need to split the box and start stripping down the engine...
 
I really like this car and that it gets used for competition. Are you rebuilding the 16B or going B18
 
Very nice write up mate looking forward for updates lovely car all the best mate

I have some plans but I don't tend to discuss them too much, tends to have a habit of making the end goals not materialise IME! I'll leave it as; I'll be rebuilding this bottom end, and it may grow in capacity. ;)

I did consider stripping it out, but it puts me in the modified classes at sprints and I don't want to roll with the big boys!

Fixed. :)

Good stuff Kozy
So would this be #3? Or a rebuild of #2?

Haha, yes, I will mix it up with them in the future, but not until I start winning stuff in the road going classes. That Dimanche sprint had an ex Nissan works F2 rally car running in the modified class, that is not the sort of thing I want to be competing against! :eek:

This will be a rebuild of engine #2, I am not expecting any damage though, it should only need new bearings and rings, but what's the fun of a standard rebuild eh? ;)

shame you had bad luck with the engine.

nice to see your getting stuck into the work yourself :)

Yea 'bout time I got my hands dirty! I only went to the garage last time due to the time of year and weather conditions, turned out to be a wise choice!

Got the box off today and half mounted the engine to the stand, could only find two bolt long enough to hold it on though so can't properly start stripping the engine until I've sourced some and released the crane. Gearbox, clutch and flywheel all came off with minimal fuss. :)

I am impressed with the fact that all 10 of my knuckles have escaped completely unscathed this weekend. A first for me... :D

Great work! Looking forward to seeing it progress! You should keep the "Flinstone" engine in :p
 
Slow progress on this as I have two OU courses pulling my attention at the moment.

Got the oily bits out...

And the offending item, big end number 4:

Piston rings all looked fine, but I'm not entirely sure what to look for if I'm honest. They didn't fall to bits, which I think is a good thing...
 
some light reading there! glad to see your getting stuck in and getting it sorted! :blinx:
 
the B series engine book is a bible :nice:

the 'modern engine tuning' book in the middle is showing some serious age with a MK2 golf kr16v mechanical injection engine on the front cover :lol:
 
Indeed, but it makes the black one look like an iPhone... :D

I need to get a crank pulley removal tool, anyone know where's cheapest? Seen one for about £20 on Motorsport-tools so far.
 
Right so I've been having a think about what to do with this, and I really can't make up my mind.

My options are:

Rebuild the B16B back to factory specs. Spunk money on the gearbox, new synros, bearings and a 3/4/5 gearkit with a long 1st. The gearbox needs attention, but this option does depend on the 16B internals being given the all clear by the machine shop.

Rebuild the B16B with B18C internals. Rebuild gearbox with new syncros and bearings. Buying unknown bottom end parts is risky.

Rebuild the B16B to 85mm bore with Darton sleeves + B18C crank and sod the gearbox. Again, buying an unknown crank, plus generally a risky build...

Eventually, end goal would be a 2 litre B16B with the gearkit and a longer final drive. No way I can get that done before the cut off date in November though so really it's going to be one of the above options.

I'm swaying towards the first option for now, then build a new bottom end next year and mate it with a 4.05 final.
 
Id go with option 3. Your gonna need to rebuild the b16b either way, so Id rebuild it better just now, then when youv got coin again, do the gearbox.
 
I'd sorely love to, it would be an immense engine, but I think the sleeved block is probably a tall order TBH, looking at nigh on £1k to do the block, then need custom pistons, mappable ECU etc on top of all that. I don't really think I can do it before December.
