2.0 or 2.3 duratec

[brianmurray325hotmail.com]

i need a few more horses, only for the road. Should i go for the 2.0 or the 2.3 duratec. i'm thinking of a cosworth "crate engine" i'd like about 220bhp. Its going into my 2007 SV in place of the sigma 150bhp. Has anybody any advice/experience?

Just cams and throttle bodies should get you near your 220 bhp figure with a 2.0. Powertorque will sell you a tuner spec 2.0 engine for £1750 inc vat. The 2.3 will give you about 200 as it comes. Will the 2.3 go under the bonnet without having to fit a Raceline reduced height cam cover?

The 2.3 will go under the bonnet without the Raceline Cam Cover

I think the short answer is that it will depend on your style of driving. The 2.3 that I have in my CSR 260 has a really strong torque curve, and whilst it will rev to 7750, and easily too, it will, equally, drive fast and very nicely not exceeding 4500 -5500, and even drift along on a whiff of throttle at under 3krpm and pick up strongly for vital manoeuvres, such as overtaking, without having to drop a gear or two. I understand the 2.0 litre thrives on revs, though probably not as much as the older K series, but with less fear of grenading, as well as the dreaded head gasket probs.

 

All things being equal, I would probably plump for the driveability of the 2.3, but then again, I am becoming a bit of an old fart. 😔

The 2.3 will fit with the standard cam cover and standard engine mounts.

If the engine was for a S3 then it would be more of a decission but for an SV which is 600kg then the 2.3 is the one I would go for.

thanks lads...a bit to think about there, the 2.3 torque sounds appealing to me

Unless you want 7500+ rpm, 2.3 all the way. For road use especially.

Never tried a 2.3, but my 2.0 litre 175bhp Duratec Roadsport has bags of torque, pulling strongly from 1000 rpm in 5th if wanted, but equally revving strongly if you want to drop your boot in second and third gears.Of course it may be different with roller barrels and more bhp. Is fuel consumption of any interest in making your decision? - my SV does about 35 mpg.

I never let the revs fall below 1800, thats also when the green change down shift light comes on anyway. In 6th at just under 2k it pulls strongly, so if I'm feeling lazy I dont bother changing down.
