    I have a 4ac sprinter and i dont want to spend $1500 on a 4age when i would only get 85kw at the fly wheel. for about $700 i could get a cam grind, shave the head, port the head and get a weber on the 4ac and it would probably be making close to 85 kw any way does anyone think its worth it.

    the turbo setup is good coz u can then sell it to a fellow 86 owner that wants revenge on their 4ac, u can sell the whole kit so they get everything they need whilst u throw whats left of your 4ac into the river

    I dont want a turbo setup because the engine will blow too quickly and i couldnt be bothered setting it all up i still think a 4ac with work would be chep and fairly good i can slide ok with a stock 4ac so one with some work i think would be good.

    lawsons lasted like 6 months and had 96km-ish if your going to do head work and shit, throw in another 200 and have a tought turbo 4ac all you have to do is chuck a thick headgasket in it and a turbo kit rather than wasting money redoing a 4ac head, theres stuff al shelf products available for it, i have researched it dude ... id go the turbo setup or the GE

    4ac's have stupidly low compression.. whack a turbo on it, thrash the balls off it, then buy another 4ac,, whck the same turbo setup on it, thrash the balls off,,, etc. etc

    4ac's are homo, not worth working seriously...

    whith a 4age in a adm sprinter do you have to get it complied and if i was to get a defect would i have to pull it out to get my car off defect or do they allow the 4age conversion.

    i dont think you would have to in SA anyway.. its the same engine capacity..
    my mate had a 2.2l in his datto 1600, he regoed that, now it has an SR20DET, he regoed that no worries coz he actually dsropped down in engine size..

    depends on what you want to do with the car..?

    also they are about 65hp in trandard form, that was 20 odd years ago when it rolled out of the factory.

    no you wont be getting anywhere near 85kw with what you have mentioned. im building a budget N/A 4ac and im aiming for about 80hp. thats with full rebuilt bottem end, higher comp pistons, twin sidedrafts, big cam, shaved head, thin copper gasket, porting, valve springs etc.

    if you want everyday turn key reliability then put a 32/36 webber on it and save for a 4age. if you havnt alreday, do suspension and brakes while you wait/have fun
