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

Huge thanks to Gordon from Engine Services for letting me video inside his workshop. I really enjoyed watching him work fellas 😊👍🏼
That is one knowledgeable guy right there
Properly interesting that one Adam . Just my opinion my friend but I'd say 400 450 tops mate is a lot you know for a rear wheel drive cozzie ya knas Adam , ya talking 175 + mph and getting that much power down will be tricky ya don't Wana write it off do ya lmao . 4-450 is enough to frighten yasel ma mate I know haha , and enough to see most fast cars off too.
Old school people who know what they are talking about (Both of you!)
Yep, me too! Very interesting and informative! 👍 Nice collection of old skool calendars too! 😂
A propa gadge doing a propa job.
This is a master class from Gordon what a knowledgeable modest gentleman,they just don’t make them like that anymore 👌
No it's not.
Hi everybody, David Vizard here. I enjoyed this video which showed a lot of useful stuff for resurrecting a YB Cosworth. During 1989 I was a consultant engineer to Mountune Racing Engines and Kent Cams. Built several of these engines for production saloons which culminated in a 277 hp build that ran just under standard boost and utilized all standard parts and just ran away from the competition. It outpower the typical (and winning) Mountune motors which at 244 hp outpowered everyone else's. If any of you want to learn advanced engine building then you will definity want to check out 'PowerTec 10' on TH-cam. You won't be disappointed as this channel reveal speed secrets that are sometimes not even know by the worlds top engine builders and designer.
DV
The word ‘legend’ doesn’t do you justice David. I spent hundreds of hours reading your articles in ‘car @ car conversions’ . Also HT racing were very good with pintos, they were in ‘fast car’ magazine a lot in the early 90’s
I've always liked watching a man that knows what he's doing working with confidence in his knowledge in front of his customer and able to explain precisely what and why he's doing. Most guys don't like being watched by the customer but doing it in front of a camera is confidence, I think you'll be happy with the results of his work. 👍
Gordon is a proper Engineer, very rare breed these days.
Fecking legend. Doesn’t need any extra work. Just loves working on cosworth’s
Gordon is a walking Cosworth engine encyclopaedia. You're in safe hands there.
The worst thing you can do is machine work when it's not needed... This guy is spot on...
Could watch guys like this for hours. Used to love going round a old boy’s workshop I knew who was just the same and would make anything from scratch after mugging over it with a cuppa tea first.
True craftsman at work .. and the satisfying noise of the micrometer is pure precision . well done that man 😁
Gordon is a true gent looking forward to watching the progress
Aside from the total engine mastery in this video, it's an absolute delight to hear the English language be spoken as it should.
Im from newcastle, this bloke knows his shit, best video in a long time for me
Wealth of experience this is the kind of guy you want rebuilding your engine, true engineer was pleasure watching him never seen this side of a build before in such detail.
Good stuff great content
Thumbs up to Gordon for letting you in and going through it all and allowing us to come along for the experience. All bang on info.
The fact that it built up that much dirt on the outside before ever being opened up is a testament to Cosworth excellence.
A breath of fresh air to see a master at work.
What a fantastic engineer Gordon is. Men like him are a dying breed & should be enjoyed while there here. A true craftsman. Fantastic work brother. Looking forward to part two Adam 👍
Used to take heads for skimming and blocks round to a very similar engineering workshop years ago. Not so many of them around nowadays. This really reminds me of the old ways things were done and it’s great to see a master of his craft at work.
Gordon is a legend. A master of his craft
This was amazing! Such a knowledgeable chap and so pleased he was happy to be filmed.
Had a few transit engines sorted from Gordon, he’s a top bloke and knows his stuff 👌
Much better than the Linford videos. Gordon is the real deal and did a fantastic job on my engine 👌🏼
I'm not a mechanic but I enjoyed this. Explanations were complete and clear.
One of your best videos that nan knows his stuff.
This video taught me I know absolutely nothing about engines 😅 big respect to this guy you don't learn that stuff overnight , amazing work !
Gordon is like a Jedi master of engine blocks.
What a nice guy Gordon is to show you his trade and know how. Top man.
Shame all these type of people/firms and their knowledge are disappearing now.
Getting increasingly difficult to get work like this done now and nice to see a proper engineer at work.
Love this. Nothing like watching a proper mechanic at work and especially on a cossie engine
Damn, when this craftsman goes into retirement, all this knowledge, all this experience, will be lost, like tears in the rain (to quote Roy from "Blade Runner")
This guy's experience oozes out of him, experience is priceless! Also........boobs everywhere is a real 90's workshop 😬
Im an actual motor engineer of some 35 years experience.
I worked as a technician at BP Chemicals oil and fuel testing.
We built 'test engines' measuring components before and after test.
Our test micrometers and scales were calibrated every time before use.
All measuring was done in a room at 20 degrees C.
I rebuilt, balanced, ported and polished my Buick engine. aka. I did the work.
I went with steel crown pistons.
Bored out the block and put a liner in. A cylinder had a crack in one of the bores.
Awesome having access to a fully kitted out machine shop.
The only thing I didnt do was spray the car. I can spray but its nasty.
Adam. As an engineer/machinist. You should have been able to do this work yourself without too much headache. All you'd need is the specs.
Gordon’s knowledge is next level top bloke
This guy has integrity! Not doing it for the TH-cam just because he loves it 👍👌
This series on your engine re build and re manufacture is great content,could watch it all day 👍🏻
Brilliant to see a man who knows his trade!
proper old school engineer, with a proper set of calendars on the wall, good man
Nice to see the engineer letting you see what he's doing with your engine, top bloke
this old boy knows his onions ,few and far between these days
A wealth of knowledge built up over the years
How nice of him to put a pic of your saph on the wall!
keeping abreast of the times i heard...
Gordon is a proper geeza
Skill like that will sadly get lost .
Well, Gordon's an amazing fellow. Good choice of engineer!
Proper old school engineer, watched every second of that, superb mate
My God, how you videos have jumped up in production. Video editing and quality, true craftsmen and experts being brought in to help you along the way. This is really top notch stuff!
Thankfully, none of that nonsense, irritating child music in the background anymore. You're flying Adam, a real pleasure to watch!
Like his special short handled ball-pien with the anti-shock/anti-vibration handle @ 23:37 for removing cam drive pulleys!!! Also, looks like no half-moons on the back of that head for the cam's bore, so only really special special, if any, line boring for this one. Also, also, it's a really nice valve spring compressor, so probably has a good spring checker too, but didn't let on!
Wow that guy knows his onions such knowledge is only gained with time and experience!!
Love to spend a few days at that shop just watching and learning a few bits.. !! Cant go far wrong with a YB cossie either.. Unless its come out of a rally car lol..
I was told by a very respected engine builder that the journals should always be polished in the same direction as the crank spins.
Well that 45 minutes went by in the blink of an eye! A thoroughly enjoyable watch 👍 It was that compelling that when I read other people's comments about calendars, I thought 'Calendars?, what calendars...?!' 🙄
its great to see this type of workmanship still in action so cracking job being done by Gordon fair play to him. Its been great to watch and can't wait to see the rebuild of the glorious Cosworth Engine.
A true master @ engines...shows he's a proper old school in his work ethics etc
I wondered why the car kept appearing and I’ve just cottoned on after 38mins 😂😂😂
I was wondering too...until i saw your comment....double D,s and all that stuff...lol
Great vid , love his cossy posters
Started watching and couldn't pull myself away. Great stuff.
Engine services is a great place, I've been there many times over the years with motorcycle 2 stroke barrels getting re bored or honed.
Love the photo of the saph on the wall, hes loves his sierras
the photos behind the saph were much better...
That was wonderful to watch, that guy (Gordon) is an artist.
Brilliant bloke, he sorted a Rover v8 for me many years ago! top job....
Superb. Ex manual machinist tech here to.. superb timing I was trying to say to a few younger techs they need to learn imperial I got the scolded look 😂 From them, it's no hard I had to learn it. Born in the year of decimalisation. To be honest machining in imperial size down to a thou or grinding to tenths of thou is much better than the metric equivalent.
When you have sooooo much work to do........and dont need social media..👍👍👍
top man.. and we love the calendars.....

44:44 Wahay 🤣
Howay man...well spotted 😂😂
All the right questions asked, worth his weight in gold that bloke. Toppa vid mate
Sorry got to say this a second time Your guy building the engine !!!! wow top marks
Soon as he said we don’t use helicoils realised he was worth his weight in gold
Dude knows his stuff
Glad you went with Engine services, always top quality work and these kinds of business are important to support
are they at dunston next to ford parts

Best blog I've seen for years
Good on Gordon 👍🏻 if there’s any young people maybe still at school watching and you’re undecided what career to choose please give engineering a serious thought👌🏻
Total respect to Gordon...I haven't got a clue about car mechanics but this is quality.
Great to see a master at work.
Now that is a very knowledgeable engineer,I could watch him work there on the YB for hours.Excellent video Adam and I look forward to seeing more of Gordon doing his magic on your engine.
Absolutely brilliant, Gordon's a proper job 👌
Please make sure you continue his interaction with the build Adam 😎😎😎
A pinto with beefy crank and a nice cozzie head, 5 grand jesus, what are we talking 200,300 horsepower must be love❤
Gordon the engine king 👑
I wish you the best bro im really enjoying your content especially lately keep up the good work proper old school TH-cam i love it mate hope your channel continue to grow you deserve it
I imagine if Gordon and Paul linfoot got together they could built an evil cosworth 💯👌
They already have 😂😂😂
@@Kevin-cs4eg learn something new every day 👍
Love to watch an old school engineer in a well used workshop, top work.
Great to see someone who actually knows what they're doing with a engine. Just seen Lee from barum engines gap some piston rings at 0.007" total. Guy is a liability
You must have been in your element there Adam, nothing better than watching a hands on engineer at work.
love these type of shops, our local guy died a couple of years back who i have used for 30 plus years . their experience cannot be replaced and to have one show you is a privilege. its mad the cost of engines most of it is time and if you want it done right it takes time which equals money . buy the right parts and your engine will be good , cut corners and you will pay for your bad judgement
Great stuff good to see someone like Gordon explain stuff
I love listening to these old skool engine builders and engineers all day. Its fantastic how much you can learn from them and the wealth of knowledge.
What a good video could listen to Gordon all day
A joy to watch a guy who knows what he’s talking about. More vids of Gordon please
Probably one of the best videos you have done
Thank you Adam. Such a pleasure to see a master at work!
More Gordon! He's a pro. Thanks for the video.
Excellent video with clear explanations to all aspects from Gordon. Nice to watch.
Brilliant to watch skilled tradesmen 👍❤️
Loving the new content, it's like ASMR therapy! Your enthusiasm is infections. Definitely helping with my mental health! Wishing you all the best.
I absolutely loved this video. Such a genuine bloke who really knows his job inside and out
Master Gordon!!
Great video!!! A master at work showing every bit of knowledge he's learnt over the decades of engine machining and building
Thank you very much Gorden from OZ
Cracking vid. Gordon's knowledge is gold. Lucky man having him let you in and getting to see the process 👍
That honing oil container looks 30 years old. Love it
How reassuring to have such an experienced builder/engineer go through your engine. Loved this video 👍
Great video... what a pleasure to listen and follow someone so knowledgeable on the cossie engine
