    Default NEED ADVICE, PRETTY NEWB

    hey guys,

    well let me intro myself, my names Gorgi. i live in the act.


    ok, well i can get or am going to get an australian spec Sprinter that has a gze conversion with a vl LSD diff and a w55 box in the car..

    my main goal is to try and get the car down to 900kg if i can and about 150 kw,

    now i plan on getting the car and doing a compression test and dyno to see where im sitting and if it happily makes 120 kw atm or even 110 i was thinking of leaving the engine and working with the body



    anyway i sorta need some direction. should i do the engine first or last?? should i put the car on a diet??
    is 150kw with complete forge bottom going to be reliable?? is turbo or SC more reliable??


    is there an issue with the w55 in this car. it does 100km/h at about 3.5k revs. is this a little bad? what diff ratio would this give me now??


    and if anyone would know the weight of an aussie spec sprinter or have a spec sheet on it i would greatly appreciate it.


    well if anyone has any ideas or input pls help or throw in ur 2 cents from ur experience and help me out please

    thanks heaps guys !

    Welcome.

    The easiest way to get power out of the gze engine is to remove the supercharger and bolt on a turbo... A few of the guys in canberra have done this with great success. Turbo has it's own challenges... running on a stock gze ecu can be done, but I personally don't recommend it.

    Also stop concentrating on how many killawasps your car has, worry about the power delivery and what it is like to drive. You want something responsive and fun, not something that makes its peak power at 6000rpm.

    Have a look through some of the build threads to get ideas.

    4.1 diff gears sit a little lower than that, i'd say you have 4.3's.

    nothing wrong with a w55, rebuild kits are cheap and they are relatively easy to source if you do blow one.

    dont touch the bottom end, 4agze bottom ends are pretty stout.

    A turbo'ed 4AGZE at 150kw is monster reliable PROVIDED THINGS ARE DONE RIGHT. Don't worry about anything fancy if you're after that sort of power, just make sure you do the work properly and sort out all the details.

    Getting it down to a realistic 900kg is quite a big ask, though you can just go as far as you feel like with it. Every bit helps, but you also need to keep the car in a useable state.

    as said before they weigh 960kg or so stock so thats alot of weight to lose, i striped the deadener on my floor in my ke and weighed it at 15kg then there isnt a huge amount of weight in door cards roof lining etc if you want to go that far. I personally like having interior haha and you dont want to start taking things away that are structural you will come to regret that oneday if involved in an incident.

    Why this 900kg number? It's not really something people usually focus on for street or mild track cars....

    What will the car be used for?


    Do the basics for weight removal, but I wouldn't waste your time trying to do any more than that..... You will get better results if you put that time into the motor......
    Stuff around trying to lose 80kg = really not that much performance gain for a street car
    Have better motor - Big performance gains

    Re; Motor - To easily achieve the power figure you want, a turbo would be the best and cheapest option. Reliable too if tuned and maintained... It's not too pricey these days to go turbo. The GZE bottom ends love it, turbos can be cheap for that power (Like the T25G of S13 SR20's)), and are pretty simple to setup..... An Aftermarket ECU will cost you, but is worth every penny for all future mods etc..... 150kw is very fun in an AE86


    The gearbox W5* is good. keep it.
