Dirt cheap gen 3 3SGE: To buy or not to buy?

    So I have been eyeing this motor for some time now. The price finally dropped to something reasonable, so I am really tempted to buy it.

    Pros:
    "Built"
    HKS Cams
    It's a gen 3 3SGE
    Lets just say that it's a lot cheaper than eBay prices. ;)

    Cons:
    No wiring harness
    No ECU
    No manifold

    Anyone know if I could somehow use my old gen1 3SGE parts so that I won't have to source another wiring harness? (Or if I have to source the missing things, what other costs would I have to keep in mind?)
    Since the previous previous owner claims that it's built, would that mean that I would need a piggyback/standalone ECU?
    Mostly looking for a way to get all the needed parts without breaking my budget...

    Thanks! :)

    How cheap is cheap?

    Honestly the motor is nothing without the harness & ECU.

    I have an extra ECU for that motor. Harnesses are actually easier to come by than you think.

    My questions are these:

    Other than the cams, what does he mean by "built"?

    Which mani is missing?

    What is your budget?


    I've done this swap so I know what you can get away with and what you can't. Based on your budget I can tell you if you can make this happen or not.

    You won't want a standalone because it's costly and won't provide you with much, if any, benefit. You need the ECU and the harness to get started. Look on mr2oc.com for the harness; you'll likely find one.

    That was what I was hoping you wouldn't say. lol
    $500 w/ a RWD oil pan and pickup. (The prior owner's intention was to shove the motor into a RA65 Celica; current owner waned to put it in an AE86)
    Hopefully, I could get it without the RWD parts for even less.

    Nice! :D

    That is why I put quotes for built. lol
    The owner that worked on it claimed that he built it, but he deleted the description in his ad after selling it.
    The new owner says that "the previous owner claims that the motor was refreshed" so I'm not really sure what to think here. Lol

    I think the exhaust and intake mani are missing? Seller didn't say specifically.
    Here's a pic from the current ad:

    How it sat 2 years ago when it belonged to the other person:

    As for my budget, the ideal would be to spend less than $1K to get it in. (not including motor cost)
    I would like to put it in myself to save on labor cost.

    Thanks a bunch for the advice everybody. :)
    Hope this works out... As many of you know, I've been looking for a motor swap for ages now. lol

    If I were you and I bought it, I'd be pulling it apart and finding out what's actually inside (and that it hasn't been put together by a monkey with a hammer) before it went anywhere near the car. I dare say from the pic provided with the current ad that that's all you get. Will $1000 on top of the purchase price even cover buying an intake, exhaust, sump, loom and ECU? There also doesn't seem to be any ancilliaries, are the Gen1 bits that you already have (alternator, power steering pump, air-con compressor, starter, etc) straight bolt-on's? For my mind, you'd be basically up for a whole 'nother motor anyway just to get the rest of the bits you need, I'd save up a bit longer and just buy one with everything already there, the lower pain amount should offset the higher cost amount, you don't want to get it the wrong way around..

    Thanks for the input.
    In the case that the motor swap becomes too difficult/costly for me, do you think I would be able to rebuild my old 3SGE using parts from this one? I mean, they are the same motor, so most parts should be interchangeable right?

    gen 1 to gen 3 is quite a different engine, if anything, seldom parts would be interchangable, not most.

    But I'll say one thing...

    ITB fucking wins hard :) I rode in a mr2 with a 20v swap that had ITB's and holy shit did that thing scream when the RPM's got high.

    I saw some of your posts on that 4AG site and based on the questions you're asking the guy, you don't want this engine. You're asking an RA65 owner how much work it will be to modify it for use in a ST162......like that guy knows. The silly thing is that you are the ST162 owner so you should know what it will take to put an S engine in an S chassis. You should also know that it is missing so many parts you need that it isn't worth looking into if you have only a grand.

    i would buy it, if it does indeed have HKS cams inside then they're worth $500 anyway.

    if you do buy it i wouldn't open the motor, just get a professional to do a leak down test on the motor, also put a bore scope camera down each spark plug well into the comb chamber, it'll give you a good indication if they have std pistons in there or not, aslo will show if there is any unusual bore wear/scrapes etc.. if that comes up sweet then you have a winner.

    to fit to an st162 you'll need an aftermarket ecu really, esp if they have fitted higher comp pistons (gen3 is 10.3:1 over the gen1 9:1 anyway) coupled with possible cams and a better flowing head i don't recommend running it of a gen1 ecu.

    you'd need to hunt down a gen3 fwd/mr2 sump(or maybe just the bottom pressed oil pan section and pickup.) and if you found a caldina intake manifold it'd be quite similar to the gen1 3sge throttle body position.

    No, it's not. The gen4 3s-gte intake manifold is shorter than the gen1 3sge and also has a different angle to the throttle body coming off the manifold. I don't think the 3sge manifold will even bolt to the caldina intake manifold honestly.

    It'll bolt. The intake bolt pattern should be the same (unlike the varying exhaust bolt patterns), but there would be lots of machining needed to match the ports.

    As far as the $500 worth of HKS cams goes, I'd wager they won't be included. Why would anyone leave in a removable part that they can sell separately? Like I said before, this engine really isn't meant for anyone on this forum. There isn't anyone here who has the means to dump shit tons of cash into making that FWD again. Just too many missing parts.

    If you want an engine take r2's lol. But that engine is missing too much.

    when i said "similar" i meant in a side feed orientation and towards the back of the engine bay, instead of over the cam covers and above the coolant nack like the NA mani or centre feede like the turbo manif.

    gen3 and caldina 3sgte gen 3.5 have the same intake and exh port/mani spacing etc.
     
  17. just_ace

    just_ace Well-Known Member

    true, he prob only meant HKS cam gears, not cams themselves.

    as per last post, the caldina mani will bolt straight to the gen3 na head.

    gen 1/2 can can not physically bolt up to the gen3/3.5 on intake or exh.

    Not to doubt you about that, but are you absolutely sure that's correct? I could have sworn I've seen 3rd Gen motors use the 1st Gen intake mani to better facilitate FMIC use......could've sworn I've seen it......

    they use gen1 mani's on gen2 3sgte for fmic.

    pic of gen3 intake gasket on tvis plates. outer holes don't line up and port matching is way off.
    [​IMG]
    even worse port matching just using the manifold minus the tvis

    i have seen in the past an adapter to fit a gen3 manifold to gen2 head in a way to remove tvis and have a gen3 60mm TB.

    people with gen3 will use the caldina mani to better facilitate FMIC fitment
