726bhp and 616lbft on PUMP fuel, with full boost by 4500. Not bad for a 2.1 litre... - Page 2 - Drifting forum

Que "the picture of stavs black sierra " and "why did i sell it speech"

Far to much money in YB's for most people to get near!

I can if you want?
Does this engine have the patented Cosworth cassette head gasket system?

Or i could just pull out the Mazworx S15 trump card and we can keep talking? Or we could go down the cost vs power argument? Or i could go into how a standard SR20 in Polo's S14 does 450hp?

Very respectable power figure though! Especially for a piece of shit ford engine.: thumbs:

i do recall stav mentioning he had one in the past, but am curious as to why he got rid if they are that good

superclarkey · 17-07-2008, 10:05

nice altho it looks as tho the power graph was done on a etchascetch lol

That is mighty power delivery for its size

Not being a massive FORD person my self, i'm guessing the YB runs a long stroke compared to the SR20, ?

Lead_foot · 17-07-2008, 10:18

Nope, IIRC standard YB's have a 91mm bore and 77mm stroke. What makes you guess that they run a longer stroke compared to the SR20?

PhatBob · 17-07-2008, 10:23

Hey! Lets have the Low vs High compression discussion again too

What sort of compression was that running Stav? I'm gonna take a wild guess in the low 7's

Lead_foot · 17-07-2008, 10:27

IIRC 7.9-1 but looking to raise it to 8.5-1

superclarkey · 17-07-2008, 10:30

because when i first looked at the post, i thought it was 726 ft lbs lol, i.e higher torque then power.. but i just misread it on an epic level.

Funny thread! Come on Stavros, lets have some comebacks

7.0:1?

Pah, if he was running nearer to 9:1 he turbo would come in earlier and he would be able to run naaaaazzzz and beat Dom's FD in a street race.

Yeah, if Fords get you so moist, and you 'love drifting, hate the scene', how come you've got a JDM-tyte-only import complete with one of the most pointless engine conversions possible?

No idea what you mean on the 1st one.

Whats the Mazworx S15 then?

Cost versus power? Go on, fire away.

Stock Cossie YBs will do 450bhp no problem too. Unlike SR20s though the stock inlet and exhaust manifolds can do it too.
Hell, if its a RS500 the stock turbo can do it too.
Can an SR20s? Nope.
And unlike SR20s, stock YB crank and rods will happily do 700bhp

What you on about?

I have a Chaser as i've always wanted one for donkeys years, before there was any in the UK. It has a RB as they chose to do it, not me, and its a bargain.

And I havent a Cossie anymore as I sold mine (after believing all the Jap bollocks hype) and cant afford another to the spec of mine as it would cost me about 8k.

Never said they the best engine, tho just about the best 2litre (well, on par with the 4G63).
If I had to build any engine it'd be a Ford Windsor V8 or similar, cheap, easy, strong.

superclarkey · 17-07-2008, 16:10

Love the way people kinda miss the point of the thead lol.

Imho, and thats it my opinion, just because an engine "can" make a amount of power on stock internals don't make it safe to do so, i mean the whole you can't run over 400bhp on a stock sr20, we ran 420bhp on a stock one without headgasket, now on the dyno it did go upto 450bhp, but i wouldn't leave it there, infact we sold the engine because i knew it was a ticking time bomb.

Sr20 will last all day long every day at 300-325whp allday long, as you go over that the engine will last but it needs rebuilds, its normaly down to not changing the oil ect and looking after it.

i mean i could pull the pipe off the actuator and make 500bhp for a few good mins..

hashiriya · 17-07-2008, 16:27

Does it really matter which is "better"?

there are a million ways you could compare the two motors and i don't think you can conclude that either is best in every aspect.

Whats important is that it is capable of doing what it's designed to. both are good engines and have different characteristics and it's a case of choosing what works best for your final objective.

Lead_foot · 17-07-2008, 16:29

I think the Mazworx S15 is some jumped up full spec drag car. Which is irrelavent as this engine is in a proper road car (used everyday, full leather trim, OAP pilot, ect)

Stavros · 17-07-2008, 16:44

The whole point of this thread was two interesting things...

Powerband (ie massive torque right from the midrange, no peaky crock of crap like most 2litres).

Mega power on PUMP fuel (ie over 350bhp per litre with fuel you buy from your local Shell station), as most 2litres with decent power are on race gas due to how they speced.

Nowt else.

And yeah, YBs are much shorter stroke than SRs.
In fact they much shorter stroke than even RB26s, at just 76mm, so the old arguments of RBs and SRs having poor torque due to short stroke is wrong.

If that was the case, in future leave out comments like this

And we will all bask in the glory of the YB's power band instead of parking yourself firmly in the YB camp and igniting a YB vs SR debate on a mainly jap performance populated forum.

I do admit the power coming out of that engine is impressive. What mods are on the car?

Stavros · 17-07-2008, 17:10

The comment was because everyone seems to swear by the SR20 like its the most amazing thing ever, even tho barring Polos it mostly been either race fuel or terrible powerbands.

Stock looking RWD Saff Cossie with full leather interior, driven by an OAP.

TKO600 box, proper diff, proper suspension, etc.

This car, tho this is a little out of date now-

Of all the people i know, the only people i know with engines in 1000 bits are cossie YB owners lol

All my mates i know who have SR20's running the same power are fine.

Id own a SR20 over a YB any day of the week, just because everyone i have known with a YB has blown it to bits lol
