Is200 1999 Engine Replacement

[abidali786]

Hi.

Im looking replace the standard engine with a toyota avensis 2.0 vvti engine. Purley for mpg reasons.

Has this been done before?

[noby76]

not sure if you are joking right?? have you actually considered buying the 'real deal' (Avensis)? IS's are mounted longitudinally so not sure if the chasis is designed to take the avenisis engine without some modification. will also involve new ecu, wiring, gearbox and the list goes on.. do you really want to take this on?? if you doing an engine swap then might as well fit the GS430 V8 in there and LPG it. . maybe easier to buy a diesel Audi, BMW ??

Cheers for the reply. It was just a thought I had to increase mpg.

Never heard of anybody doing that....

Seems a hell of a lot of effort for mpg gain and so much work would have to go into it. There's no way it's a straight swap, All avensis engines are 4 cylinder for a start and mounted completely differently.

:) If your going for a full out engine swap go for a cosworth 4 pot. Would be easier than fitting an engine from an avensis.

Would love to see a sierra/escort cosworth engine in an IS. :)

This would be the perfect combination! the only thing letting down the Sierra and Escort cossies was the car it went into :shutit:

I agree. May as well just get a Avensis, they are really good cars and surprisingly as well equipped as a IS

used to be ford man and still like fords.. cossie engines are masterpiece but why bother when Toyota has the Altezza? which is effectively an IS and has one of the best racy 4 pot engines? its effectively two engines in one. keep it under 6000 rpm and will drive and consume mpg like any 2 litre avensis. keep it between 6 - 8000 rpm and you have a light racing engine.. tbh abidali you better off with an Altezza 4 pot. which means you get to have the same chassis with a 4 cylinder economy/race engine..which ever one you want at a given time.. :winky:

[Mr.Rudus]

if its mpg concern Abid, you rather go for a Toyota avensis 2.0 litre vvti cdx auto, 150bhp, leathers, 6 disc cd changer, the works.

its as good as the IS without the name lexus. .

avensis aprrox 40 mpg combined

IS approx. 28 mpg combined

hope I have helped the confusion out for you -

Yes but can you tune an altezza 4 pot to 500+bhp and have 4 wheel drive as well?? But in the real world, you are right the 4 pot altezza engine is the best of both.

[noby76]

if the op wanted 500bhp he could still have it with the Altezza engine in GTE spec.. but mpg was his sole reason for wanting the 4 pot Avensis engine! tbh honest I actually wont mind a high revving 4 pot Altezza my self ..petrol still aint cheap these days..

@Abidali

if rear wheel drive is not an issue have you considered the I-VTEC Saloon Accords in Executive trim? they are fully spec'd and in honesty looks better than an Avensis in my opinion. I have been looking at those in the 2.4 litre spec but as mpg is on top of your list then a 2.0 will do the job nicely with mid to high 30's mpg on the combined cycle. Accords are very well built cars and no one laughs at Honda drivers..
