Can some people but in more techinal terms etc how far ahead of it's time the YB was and what was so good about it.

I am talking to this lad who is saying he can appreciate the Cosworth for what it wa setc but the engine is not all that. I know he is wrong but need some techinal jargon to shut him up something i am not to good at.

I am no blinkered cossie owner what wont take his answer i have had jap cars etc but always return to cossies.

So a little help would be appreciated thanks

Ginge !

they where 4pot cars that delivered just under 400bhp on the standard engine internals

they also are fucking heavy and take 3 people to carry into a first floor flat

Ginge !

also came with steel rods and crank as standard and was the best 16v engine of its time and took 10 years for a better 16v 2.0 engine to enter

they skyline was also a better standard engine,,,,, and it PISSES on a cossie even though it weighs more than the moon

IMHO the YB wasnt particuarly ahead of its time.

What is was though (even by modern standards) was built to a standard not a price.

Steel crank
Steel Rods
Very strong pistons
Fantastic exhaust manifold design despite the expense of making it.



I believe that an engineer at ford at that time had pictures of one of the accountants sucking off a goat.

There comes to a point in the project where the engineers submit what they want, and then the accounts turn round and say "you cant have that" and do stuff like put rods in an Evo that cant really take 400bhp, let alone the 600bhp+ that the cossie ones from far earlier can, at this point the engineer pulled out the picture of the accountant sucking off a goat, and threatened to go public with it, the accountant then just signed off what the engineer actually wanted for once.

YB - 1985
XE - 1987

Ten years can really fly, as quickly as in 2 years sometimes it would appear

I was mulling over a way to answer this politely when chip popped in and did a better job than i had actually come up with anyway...

Perfect answer IMO.

Ginge !

so a xe can do 400bhp with no internal mods ???

dont they also suffer oil surge issues on track too i once heard

so im not that wrong it would appear

though the xe IS a very good engine that can take more abuse out the box than a cossie engine can

SapphyMike

dont know about the power, but cant any car suffer oil surge problems on a track?

thats like saying wearing a read jump suit infront of a bull "might" make it chase you and want to beat next weeks shit out of you?

Ginge !

sorry just asked a few people about the xe engine as im thinking about building a corsa for a cheep toy with a xe and was told that they have surge issues when used hard on track

thats why i also asked,,,, wanted to get some info in a cheeky way

Tank Mike

i think what he means its, your much more likely to ge t oil serge from an xe than a yb which i can see to be true after talking to a guy with a 2l nova track toy

SapphyMike

A cossie will get surge if cornered hard. gravity etc is such a bitch

Billabong

The YB's biggest claim to fame was it was first to break the 100 BHP per litre, for a road car. As already said, it was over engineered, which meant it was relatively easy/cheap to tune.

A couple of choice quotes for him:

Stavros

Just some more info to help the "ginges totally wrong" game...

GTST skylines weigh same as saffs, and R32GTR skylines weigh less than late spec EscCossies, so not quite the moon...

PS- i can think of lots of 4pot engines that can do 400bhp on stock internals. wouldnt say they have as strong internals as a YB, but sure can easy enough do 400+

Martin-Hadland

iTrader: (2)

So what do R32 GTR's weigh then? R33's are 1600kg +

Stavros

Early R32GTRs like mine are 1430kg, late ones with the crash protection in the doors are 50kg heavier.

IIRC Gaybird said late spec EscCos with the extra crash protection etc are 1500kg+

Ginge !

im totally wrong ?

what engine can do 400bhp from a stock engine,,,, where the bottom end can take more and the limit is the head flow

id like to know this ?


thats a 2.0 4 pot with standard cams and just extras bolted onto the "service" engine back in 1986 ?

intrested why people dont tune these asmuch if they did ?

Billabong

From the GTR forum.

EsCos kerbweight was 1275kg (full fluids, full fuel tank). Can't remember the late EsCos kerbweight, but don't think it amounted to over 200kg extra? And IIRC, Mike's figures were from a weighing session with his car.

rabmc

Good read this , some intresting facts

Martin-Hadland

iTrader: (2)

I weighed a customers small turbo (but converted to 550hp) Escos and even with a huuuuge stereo, big brakes etc it weighed in at 1386kg

Stavros

Before 1986 isnt that common, but a LOT sooner than 10yrs later mate like you was saying, tons of engines.

Like said, dont make em stronger, but dont mean they cant and dont do it.

Off the top of my head tho I can think of.

FJ20ET. 1983, and is a lot more commonly tuned in other parts of the world than Cossies.

XU8T 1985? Only 1.8 too.

Im sure there tons more, but they the 1st 2 i can think of.

The world doesnt revolve around UK tuning, thankfully.

Then what exactly is your mate appreciating then? As the whole point of a cosworth IS the engine. Sounds to me like he is trying to wind you up mate.

nilrem

i suppose it was the cossies and lancias that paved the way for scoobies and evo's... and you can still get a cosworth to the levels of those cars today...

Ginge !

this car was a REAL ahead of its time motor !!!

look at the date it was designed and made too !!!

Mike Rainbird

It might weigh that with you in it, but certainly not with me in it .

My car was a tad over 1400kg with full tank of fuel, and a 20kg parcel shelf .

Mine weighs under 1400kg in "track" spec (parcel shelf and spare wheel removed) .

The YB wasn't terribly ahead of its time, as it was built on (specially selected) Pinto blocks which even then had been around for ages.

Twin cams and 16 valves were already found in the Triumph Dolomite Sprint, but as already said, the YB was built for a purpose (to make sure Rover didn't win any more touring car races) and thus to a standard, and not to a price.

Ginge, ive killed two cossie motors on the road due to oil surge, and no XE motors on track, hope that helps

Why do you think so many people have "big winged sumps" on their YB?

Its only when running very sticky tyres the XE's tend to suffer on track, where as you can kill a YB on nangkangs

Stavros

and counless other cars, it was 1986 not 1966

JonnyBravo

Ginge- I'll sort you out with a proper sump for a xe if u like

You'll need to wait 3 months for it though

Well statistically I had to post something that wasnt bollocks one day if I kept trying

HERE IS A FACT FOR YOUR MATE

Cosworth sourced the alloy for the cylinder head from the finest
metals,which were religiously tested for the best quality

Mario Illen who did some of the design on the ybb and ybc
heads went and started Illmor,with another Cosworth Employee
Illmor seemed to do quite well with some poncy firm called
Mclaren and Mercedes,they won the Formula 1 World Championship
if i remember,which wasn't the same as winning the British Rally
Championship and the BTCC in a 3dr sierra as Cosworth did
