    sounds interesting.

    Not sure if it can be done or not sorry! A few questions I would raise is would it be worth it? Bearing in mind how easy it would be to drop a C20LET in and also how tunable the C20LET is. Are the mounting points the same as the calibra lump? Is the turbo situated in a place that you will have space for in the engine bay of the astra?

    Interesting project as like you say it would be very different, but I know from experiance that different costs money compared to a tried and tested option

    I will look forward to seeing what people come up with on this.

    I have a mate with a SAAB and he wanted to change his engine for the turbo engine as he has owned vauxhalls before and knows how easy it is.

    He has been advised to sell his car and buy a turbo SAAB, it is not as easy.

    Plus, SAAB bits cost more to buy. Thats why he buys vauxhall brake discs and pads!!

    The Vauxhall brake discs on the Z20LET cars have SAAB part numbers and logos on them, so you can't get better than genuine SAAB from Vauxhall at a discounted price!!

    The Saab had a 'low blow' turbo if I remember rightly, so that it was more torquier low down, but this will be at the expense of 'tuneability'

    To be honest, for the hassle of fitting a LET into a MK3 now I would sell it and get a nice clean Cav or Cally Turbo that has not been meddled with, then tune it up. The 4WD system makes for a better overall package and will be cheaper to insure than declaring an engine swapped MK3 1.6

    Swapping the engine could be possable, but the costs like the other guys say could be expensive. the saab 900 from 93 L i believe?... uses a revised mk3 cavalier chassis so alot of the components should be interchangable. Its all GM so it could be done. But the engines are of very diferent tune i think, such as the low blow turbo, the turbo gets used alot more often and at lower pressures to create a much more torquier and drivable engine, where as the C20LET Vauxhall engines wer designed for the sportier of the brands, hence the cavalier and calibra turbo's, which were marketed as powerfull vehicles. I dont know much else about it but i though i'd write in anyway. I'd go for the Vauxhall Engine..... Its cheaper, i think its more powerfull and there has been thousand of people tuning it for years now. The BTCC Cavaliers even had the head of the engine the opposite way around to aid cooling and ram air into the carbon induction system. A friend of mine is trying that now in a tigra!! So... theres alot that can be done with that lol.

    it was just a idea as my mate has a saab 900 turbo and where possibley putting a 2.3 turbo in there in the year.

    im still considering going the mantzel route on my astra and keeping it but it needs to be in a fit condtion first as its got a few little niggles

    but the saab has calibra subframes and basically all vauxhall parts

    All well and good steve but unless vxl's 4x4 system is kept in tip top condition it goes wrong and is crap, even tyre depth's make a difference.

    I would never buy a vxl 4x4 system(well if i was breaking the car i might).
    Cant Think of Anything Funny To Say
