A Few words on the Cosworth engine from
www.burtonpower.com
An incredibly famous engine, the Cosworth YB Turbo actually began life in 1984 as a N/A Cosworth YAA concept. However, the turbo version was launched in the 1986, 3 door Sierra with 204bhp. The infamous RS500 version of the same car followed in 1987 with 225bhp, a bigger T4 turbo, eight injectors (only four connected) and an engine designation of YBD.
Perhaps the most plentiful Sierra, the Sapphire hit the roads between 1988-89 with a 4x4 version being produced from 1990-92. The engine was subsequently available in two versions for this latter car - The YBJ, which incorporated many of the RS500 motorsport type revisions, plus the green cam covered YBG, meant for the US emissions sensitive market. This had three cats, closed loop lambda control and ran on 95 octane unleaded.
Finally the Escort Cosworth took over from 1992 with the big turbo YBT engine, featuring a T34 and four wheel drive, whilst the series came to a halt with the introduction of the T25, small turbo Escort between 1994-96. This also featured Ford EEC IV management, with wasted spark ignition, twin coils, a different series of injectors and a unique black cam cover.
The most common engine is the original YBB (3 dr and 2wd Sapphire), which can be easily tuned with chip and turbo modifications to increase the boost level. However, the 4x4 head is the ideal base since the early type has less water jackets and is susceptible to blowing head gaskets with serious hikes in boost.
To begin with, you’ll need to upgrade the actuator to -31 (dash 31) type and upgrade the management chip to increase the fuel and boost level too - this will typically be to around 270/280bhp. We would recommend that you also fit a good stainless exhaust such as our Mongoose range, plus a K&N filter.
After that stage, you need to swap the injectors for 803s - commonly known as Dark Greens. To this you’ll need a different chip again, plus a 3-BAR MAP sensor to up the boost to 19 PSI (1.3 BAR) resulting in approximately 320-330bhp.
Beyond this level, we’d recommend fitting a Group A or multi-shim head gasket and for extra security in high-boost applications, and an ARP stud and nut kit.
However, around this level, the standard Garrett T3 turbo will have reached its limit although there are now several paths to take in turbo choice. These though are always a trade off between turbo lag and driveability - hence why going straight to a T4 isn’t always a good move. Popular choice is to fit an Escort T34 or a hybrid T3 along with a larger intercooler. T38’s are also available although these aren’t an off-the-shelf Garrett unit and are seen more as a hybrid. You should see power potential with this to around 460bhp, whilst the T34 will give you power to around 380bhp.
At this point - and especially if you want to use a T4 with power potential to the touring car levels of 540bhp - the engine needs to be purpose-built to suit. The reason is you’ll need extra head work in terms of porting, different cams (although BD14s are the limit on the street), lower compression ratios and long stud conversion. The trick is making the most of the unit whilst producing power without huge amounts of lag. Once you get to this stage, we can advise you on the best way forward, depending on the type of engine you have.
A different route, and still popular way to tune the YB, is to return it to the original N/A application, which involves raising the compression. For this, we stock Accralite forged pistons to increase the ratio to as much as 12.5:1 although they can be machined to lower the CR since they have raised crowns for this purpose.
On top of this modification, the head needs the ports seriously opening out and for ultimate horsepower applications, larger valves installed. The cams too need swapping for non-turbo profiles although they aren’t designed to work with the standard YB hydraulic lifters and therefore need converting to solid lifter type.
The bottom end is fine for this type of aspiration since the rods and crank are both steel. We would recommend however, that the rod bolts are upgraded for high-revving applications. For ultimate power though, we also stock steel H-section rods. Lastly, you will need to swap the turbo inlet manifold for a twin DCOE type allowing either 45/48 side draughts or throttle body fuel injection. In this form, you should be able to achieve in excess of 225bhp+. - ยานยนต์และพาหนะ
Your not out your comfort zone your upto speed. This engine built is one of the best things on TH-cam your background is kicking in well done Adam.
Thanks Richard
500bhp is a bit ambitious without forged pistons and rods also the block will need long studding maybe a chat with lee at barum engines maybe have oil jets put in the block also that spray the underside of the pistons
Well said! I forgot all about the oil jets my friend! At 500bhp will defo need the ARP long studding, forged pistons and a full blue print! I'm sure there is also an oil pick up pipe that needs to clear one of the big end studs, as it's very tight on the 4x4 engine. In all honesty I wish him every success, but if he ignores the advice, it's his hard earned money and time going down the drain.
Adam and his mrs and the Bairn on bean skin and crumb so he can finish his cosworth engine 😂😂😂
Desperate times Peter 😂
When I had my engine built and mapped by Ahmed bayjoo he told me to keep the standard flywheel, gives more “throw” and in turn helps with torque
@@Adam151082 as long as that cossie engine gets sorted everything will be worth it man ha
Lol ... money well spent tho !
Fair play to you Adam. That's definitely a ballsy move to take on a job like that. I wish you all the best.
This is a major project Adam, looking forward to this build. It's always great getting new shiney parts delivered. 👍
Great vid Adam, been following the cossie build and love it, but this engine build series is epic so far..... it’s going to be a monster 👍👍
Awesome work Adam, looking really good. I always loom forward to see what you're upto. Cheers Mate.
good on you adam you got yourself well on the way to that 500bhp rwd cossie what a machine that will be i cant wait for this engine to be rebuilt so we can hear it running
Seems like a lot of people underestimated you, that rocker cover was bang on. Colour popped nicely
Good job on the rocker cover, u get a good feeling when u do it yourself.
Adam cannot wait for this to be done! Good work matey 😊👍❤️
Real life real geezer real cars well done Adam proud to watch ya keep up da good vids
Cheers fella 👍🏼
@@Adam151082 true mate love watching
Quickly becoming my favourite car youtube been watching alot of your old videos great content
Looking forward to seeing this engine being put together. Will be some machine. Nice work mate
Nice nice adam, love watching the process
Really enjoying this series Adam 👍🏻👍🏻😎
You need a long stud conversion and some decent rods for 500bhp. Depending on compression ratio and the boost you will be running it will lift the head. 400bhp is cutting it fine
Great video , lots of nice parts 👍👍love it
Brave man, fessing up to your spending with the mrs having access to ya videos 🙈🤣
Nice one mate, enjoying this one... go hard 👌
I'm not a Ford fan, I've never been interested in Cosworth engines and I have no idea how I ended up watching your channel. You're doing great and it's really been interesting watching your videos, I look forward to seeing how the car and engine progress.
Exciting, keep going lad 👍
Assume you know about the arp long stud and nut kit? Apparently if you don't bother with it on high power builds, the head bolts can pull on the threads causing high spots in the block and subsequent head gasket failure. Look forward to the next video.
You need to talk to Lee at Barum Engines
Get the long studs done and machine the pistons to the deck height.
Guessing you aren’t having uprated rods as well ?
Are you having the long stud conversion?
Great vids always like to watch
Your a good presenter
Adam. It was me you were talking to at the traffic lights earlier.
I must have come across as a right nutter. I was a bit excited 😂.
Adam is as nice a guy in the flesh as he appears in his videos.
Thanks for giving me a few minutes of your time while the lights were on Red.
The car is looking class!
Haha. Hey Jonny. Hope you had a good train in the gym 💪🏼
Good on ya mate for giving it a go.
Love the rocker cover you have done a good job on it
I have heard of some liners cracking in these cosworth blocks if bored out too much so I would just double check to make sure there is still enough material left in to run big power
Awesome content Adam, 👍👍👍
Sending Velveeta from America! Nice update, thank you.
Hi Adam very entertaining,especially in the engine shop,he knew his stuff, see if you can video your build in Timelapse with the machining
Mahle are wicked pistons. Your GMT 2 is also wicked!
Great video Adam, as always 👍
What are u doing with it when it's done, putting it in the 3 door?
Nice 1 Adam 👀👍👍
Now then Adam. I always love to watch your videos ❤ but you say Hiya fellas well what about us 90's car crazed girls 😊
It'll be worth all the investment Adam!Great content 👌
Some lovely engine kit there.
Subbed. For no other reason than "I'm going to rebuild a £5000 cosworth engine myself" followed by "I think it's called a gudgeon pin or summink". 😂 Madlad.
Hi Adam. I've just started watching your channel and thoroughly enjoying it. Nice to get the tour of the engine rebuild shop in the last video. The parts list looks solid. Do the new pistons have offset gudgeons? I think Cosworth changed to offset in the later years to prevent piston slap. Usually not a problem until higher mileage and cold starting. Regarding that flywheel, I hope you don''t mind me saying it but I really advise to stick with a 7kg weight minimum. Turbo's like to have something to push against (flywheel) and you may find the new engine will smoke tyres instead of putting the power to the road. Cheers!
Nice flywheel. I have the 900nm billet clutch kit with flywheel from them. They are the way to go when big hp.
Don’t forget to add the rocker cover costs aswell Adam
Is the weight loss on the flywheel from the machined out holes
Loving the build so far
Great vid again. I’m wanting to buy another cossie. Had 2 back in the day one on an E reg with chrome engine that was a real pig. Anyway at the moment I have nowhere to keep it. Wouldn’t dare leave it outside on the road all night
Can’t wait to see it finished are you putting it in the cozzie you bought from Scotland ?
💪🏽🇬🇧👍🏽 new to this channel , brilliance
Adam, make sure you get the pistons, Conrods, crank, & flywheel balanced you won't regret it no matter what anyone says.
This is epic 🤩
Adam make sure you replace cam shaft bearings , cam spacers and rubber o ring which goes on the bearing housing . I made this mistake by only replacing cam seals and it turns out the rubber o ring had perished slightly and was still leaking oil when put back together. Cam spacers had slightly worn too which didn't help. Bought all these parts from graham goode and the didnt cost much . I hope you don't think I'm telling you what to do mate but I learned the hard way . Love your channel buddy I'm always Checking and waiting for your next video . I am in ireland and have a 350 bhp sierra sapphire , flint grey so if you are ever in ireland on vacation and want to make a short video hit me up . Keep up the great vids bubby , all the best .
Shown them cam seals on last video when at the engine shop. We’re brittle
Ant mac partling pet haha
Awesome haul man, it seems like Christmas again 😮lol 😊
Adam - Most Cosworth parts are very expensive. I had a Cosworth Vega and the only weak spots were the aluminum block ( GM cock up) and the injection (another GM.....). Both were easily fixed.......pressed in sleeves and Weber DCOE carbs and manifold. Don't spend all your beer money on parts! LOL Keep the Faith, Tom P.S. You'll really like the lightened flywheel.......that engine will rev like a chainsaw! LOL
I would advise having the crank, clutch balanced mate, as well as the rods and pistons.
Will you have the block long studded , who will you get to balance the crank/clutch/con rods etc ,
I said it before I’ll say it again. That rocker cover looks ace … well worth some cheesy beans … 👍
I think your doing amazing job
Anyone has any tins of beans 😂 Adam you are a legend mate 👍 why I love you're channel pal ✌️ but bet that engine will be given the beans😮stay safe mate
Are you considering upgrading the conrods Adam?
Send it to barum engines in Bristol. He's the man for this job. Got a TH-cam channel too. Nice fella and works old skool. Well know Cossie engine builders
What's your plans with engine when rebuilt are you keeping it for one of your cars and selling one on just wondering
Were the pistons specced for your correct compression ratio for your 500bhp? Do the gudgeon pins have a wall thickness designed for thr power tou are aiming for? Im not sure what guidelines you are following for a reliable 500bhp pump fuel cossie engine. Cheers
daft question but would you swap the big Ben on your wrist for a cav
2:04 in Canada we call that a wrist pin.
Money well spent I'd say Adam 👍🏻
Hi Adam I’m surprised your missus hasn’t made you live in the garage after that spend lol, cheesy beans more like brown sauce sandwiches for you mate 😂. With that power do you know if the original con rods will be up to it? , be sure to get your crankshaft/ flywheel and clutch balanced together before you build it up. 👍🏻
Make sure to gap the rings proper Adam, if you throw them in without checking or probably opening them up for more boost disaster will strike mate. Might not be a bad idea to get Gordon to gap the rings tbh, vital the top ring isn't to tight mate.
I feel a cosworth escort build on the way ✌️🇬🇧
Nice job on the cover if it's high temp paint often it needs to bake on so be warey of the time it sits or the paint might start lifting off 😢
Hi Adam, we buy Lidl own brand tinned sausage and beans for 59p a pop, try 'em they're really nice.
Hi Adam your skimming the cyl head is the head gasket standard or thicker the holes or notches on the head gasket will tell you ..if you fit a standard the pistons will hit the head .. gudging pins go through pistons
😂
I went for the acl bearings when built mine up and the apr bolt’s and stud kit and a bigger oil pump sold now wonder how it’s held up built in my garage 🤔😂
Nice watch
Act clutch for that flywheel 👍.
Have the piston ring gaps been checked already?
What car is it going in Adam 2 door or the Saph or something totally different ???
Hey dude what were your machinists costs for the rebore ect?
It's so cool watching this build Adam love seeing what u have bought & how it's all coming together don't worry about food just keep building mate 😀
Adam you can't be rocking a Rolex asking people to send money for beans 😆
Are each piston balanced?
had a ttv flywheel on my gti6 certainly made it rev faster a good upgrade on any performance car had issue with starter not lining up after fitting it , had to space it out from the bell housing as ring gear on flywheel wasn't in same position as previous one.....just saying. hope that .5 oversize is enough to remove scratches in bore as must remember its .25 either side of the bore to make .5 which is fuck all if its a scratch that your finger nail can feel.
I suggest before you rebuild this engine there a video about major engine faults on these old engines you be very surprised how many faults these engines have worth a look for piece of mind
Are you going to put this in the 3 door? you going to make it four wheel drive?
Adam how far from Whitley bay?
Burum engines do the long stud conversion there on TH-cam
Wicked video mate what a legend you are build this engine and I will take you out for a jacket spud and cheese,Beans meal mate as long as you pick me up in the car this engine will be in haha
Engine shop didn’t charge to polish crank and the other bits and bobs he did?
What you going to put it in when it’s finished mate ?
Light flywheel will give less engine braking not more 👍🏻
Is it going in the sapphire
Adam how much was the guy to check out the engine.
Pot noodles are good may be go into growing your own veg
Some nice bits and pieces 😊
👍
I watch alot of racing channels mate, what many of them do is to grind the ends of the piston rings allowing a 2000th of a mm gap when fully seated, check youtube for this as it seems to gain HP.
Search youtube for (How To Properly Gap Piston Rings).
th-cam.com/video/uAguO3EPzcI/w-d-xo.html
Forged pistons and Conrods are a must for 500bhp in these engines
i think he asking a bit much out of standards parts . pushes 500bhp that lasts 1 day on the dyno .boom
👍👌
Nice Rolex 👌
Taking weight off rotation is the best thing you could do for an engine
What about the labour? You forgot to mention
If you do go for better rods speak to mar motorsport bridgeway rods half the price of arrow ect on par spec wise tested well over 500
Nice Rolex by the way. Which one is it?
Without race fuel or some sort of E70+ those pistons will have very short lives at 350-400hp, nvm dreams of 500.
2 Cossies a Cossie engine being built and a Rolex, and you want us to have a whip aroumd so you can have some cheesey beans 😅
