    just wondering are 3s-gte engines simple enough to convert to rwd and are they a good way to go instead of say a sr20 conversion

    I'd pick a 3s for a few reasons:
    I don't like Datsuns
    I don't like sr20 heads
    Keepin it in the family
    from looking, not from experience... 3s internals look better.

    But that's just me.

    its not cheaper than an sr. not even close. you would never do a 3sgte unless you had a lot of hooks up for cheap fab work, as everything is custom.

    there are no versions of the engine that are cheap/easy to rwd.

    i just posted on HR about this, ill dig it up and post it here.

    it is a tricky conversion. while you will have close to double the power of a 20v. it will cost you twice as much. and take a lot longer.



    there are basically 3 types of 3sgte.

    all of them come from cars with transversely mounted engines. (fwd,4wd,mr)

    so in every case, the intake, exhuast, and sump need re working, plus all the plumbing. also distributor/cas placement will need to be looked at.


    gen1/2. these are considered somewhat fragile by some. but realistically, the the power they are happy to produce reliably is a lot of power for an ae86. they are also quite cheap. the factory ecu's on most of these engines uses an afm, which is in practical terms is something to avoid. these motors can use 2s rwd (corona) sumps with a few mods. so that part of the equation is comparatively easy.

    gen3/3.5 are a lot better motor in every way. the later caldina engines also use coil on plug with a crank trigger. meaning there is no prob with the dizzy at the rear of the head fouling the firewall.

    the sump though is much more complex, ive seen the stock one modified, and also BEAMS 3s ones used also. still youre looking at greater expense here compared to the gen1/2.

    all 3sgte engines also have a common problem in that the stock flywheel isnt really too handy for rwd. the teeth on the ring gear are beveled the wrong way, and there is no provision for a spigot bearing.

    compatible rwd box/bell combos do not position the input shaft close enough to the engine just to put a spigot bearing in the crank, if needs to be in the flywheel.

    then you will need a custom intake. probably a custom ex' mani, custom piping too hook up your radiator (and a decent sized one) custom end mounts, custom tail shaft, custom gearbox x member, custom IC piping.

    makes an sr very seriously worth considering if youre really thinking you need 2L turbo power.

    that said, you dont need 2l turbo power Smile

    i wouldnt expect many places to quote you less than 10k drive in drive out.

    A few of the guys in Altezzaclub have turbo'd their 3SGE Slydar. Should be plenty of advice on there.
