1987 Ford Sierra RS 500 Cosworth from UK and Ireland - Comments

300bhp is no where near the limit of a honda engine, that was just a turbo running at 5.6 psi.

Read the whole lot before commenting please not just last few entries.

It may not be the limit for a honda engine in general, But for a VTEC? Maybe near it, the whole point of VTEC's are to have good power and economy, and arn't realy made for high pressure turbo charging. But cars like the cossie arn't really thinking about economy, they are a tough engine ment for power only.

Ye I know that, but with a turbo you don't lose VTEC you can still rev to 9000 rpm, but have the turbo pull from about 4500 revs (on my turbo anyway) all the way through to the limiter. 700hp honda vtec turbo's are not hard to find just less of them about due to the cost. with the turbo and manifold, lower compression pistons, bigger injectors, uprated fuel pump and piggy back ecu for fuel control pretty much the basics for turning it into a turbo car it works out quite expensive. but the actual block is very strong and responds well to forced induction, I've seen civic turbo's running 35psi of boost and even 1 running at 42psi...that 1 prob didn't last long, but then again not many engines would at that pressure.

I would take the cossie engine anyday of the week!

I believe the cossie producng the most bhp came from Sweden and it was producing about 750bhp. I read this in Fast Ford mag years ago.

It was also coloured in the old touring car colours.

Looked sweet and went like absolute stink.

To the Honda loving guy >If you feel so passionately about Honda's then why don't you just go to a forum dedicated to Honda's?

I know people have the right to air their opinions, but your continous baiting of the Cossie is wearing thin and is getting repetitive.

I don't own an RS 500 but a modded Sapphire Cossie pushing 380bhp which is enough for me! lol.

Plus get your facts right about the S2000!! Made me laugh! It's a 2 ltr! yea right!

2.2 is the correct engine size as per Honda's website!

'2.2 is the correct engine size as per Honda's website!'

Wrong! It's a 2.0 Litre, always has been.

The UK Honda S2000 is a 2 litre. I think you're looking at Honda.com. Having said that I'm a massive fan of the Cosworth engine. It may be old and a bit heavy, but it's a hard act to follow!

Omg another silly person thinking the s2000 is a 2.2.

The S2000 engine came in two variants of size depending on year and continent you live in.

When it first came out it WAS a 2 ltr engine, but they did then introduce a 2.2 a couple of years later.

Hope this solves this issue.

Still would rather have a Cossie lump tho!!!

Thank you.

2.0 16 valve NA honda 237bhp

vs

2.0 16 valve TURBO ford 225bhp.

Rather have the honda thanks.

The UK S2000 still IS a 2 litre, and always has been.

Only when you rev the nuts off it, the torque figures for the S2000 are only 150 lb ft (no turbo you see). And the cossie, like most turbos has a torque reading similar to the BHP reading, about 220 lb ft. Its torque that counts when it comes to acceleration and pulling power.

Torque shmorque, if torque is what matters then diesels would be king of the road!

Really odd debate this, both are superb engines, one is best 4 pot na engine in a roadcar ever and the other is the best turbo 4 pot engine in a road car ever, they cannot be compared really.

I wish more manufacturers would put engines of this quality into road cars, modern hot hatches are barely tunable compared to the old school Cossie.

And the S2000 has always been a 2.0 in the UK, but in other markets it changed to a 2.2 a few years ago.

No not really, diesels have high torque, but no BHP, petrol turbos have both good torque and BHP, VTEC's have high BHP, but no torque.

High bhp and no torque... just like a F1 car then.
