Gday guys, I have a few questions that I need answers to. My celica is a 1986 celica sx. It has a '3s-ge' engine, but I went to 3 different aut stores, and none seemed to give me the correct spark plug leads, the leads these shops gave me were all too long! is there any chance this is not a stock engine? I would have no clue, so I will upload some pix at the bottom if thats ok. I would like to buy a new valve cover gasket set, but when I type in the specs for this car on the internet, I keep getting told that I need to buy a lhs and rhs valve cover gasket, but this valve cover has a single gasket (looks exactly like the 3s-gte gasket), so what should I do? I would like to replace the head gasket, piston rings, valve cover gasket and a few other little things, but I am confused as to what parts I need, because it seems everything I am getting given for this car wont fit it.... Also, are there any aftermarket cams that will fit this engine? call me crazy, but I would like that little extra grunt with some upgraded cams as I will also be upgrading the intake and exhaust. Thanks alot for any help you guys can give me, cheers.
you're having those problems because you have a 2nd gen 3s-ge valve cover or head on the 1st gen 3s-ge. the 1st gen 3s-ge does have TWO valve cover gaskets as shown here: this is the normal 3s-ge covers in our car:
Other way around I'd reckon - they've put a Gen2 head on a Gen1 block, though from the O2 sensor position it appears to be running the Gen1 headers? Bizzarro... Mayb they just put the cam cover from a Gen2 on for lols or something?
Thanks for the help guys. The spark plug leads I got for this car ldidnt fit, so I doubt they have just put on another valve cover so im guessing, for anything to do with my engine, I have to look under celica st182 3s-ge?
I would agree everything on that engine looks to be gen 1 1986-1989 with the exception of the valve cover, close to the 88-89 All Trac (3sgte) valve cover but not quite the same. We can actually narrow the engine down to an 86-87 3sge since the exhaust manifold has an O2 sensor on it. The valve cover looks like its from an AE86 ??? don't know what that is....but I'm sure some of you do
i studied your picture some more and i'm 99% sure that you have the 2nd gen 3sge (at least the head) made to run with the 1st gen 3sge electronics/intake/exhaust if you look at the casting of your head just under the valve cover in front and just above the exhaust heat shield you'll see circled, two bolt holes. those are for the ACIS intake manifold for the 2nd gen 3sge as shown here: so your head and valve cover at least is from a st182. with intake/exhaust/egr/electronics from a st162 3sge
Nice detective work eNtrax :thumbsup: So small-port head with intake and exhaust from big-port head - how well does the car run, lincellusion?
another abortion job of fitting a gen2 engine with gen1 manifold. i'll tell you how it runs, gutless until 4400rpm when the TVIS opens, that is if its operational. it's such a mismatch fitting the tvis butterflies on the gen2 na head. it drastically strangles it when the TVIS butterflies are shut, and even when they're open you have the divider of the 2 small tvis runners blocking flow right in the middle of the port. i'll get pics if you all need to see. it's the 4th one i've come across. the good news is that you can fit any 3s cam advertised for the gen2 3sgte motor.
Thanks for all the help guys. Yes, the car runs surprisingly well for an 86 model 4cyl car with 220000kms, but I strongly agree, its only at hogher revs that you really feel something. I do think this car would have either this gen2 engine, or atleast the gen2 head. If this is the case, and I want to replace head gasket and piston rings, what should I search for that? I dont want to end up with parts not fitting my half apart car ;( so you saying I can get any 3sgte upgraded cam (without going crazy) and it will fit fine?
not all 3s cams, you need ones specified for the gen2 (3sgte or gte) but not gen3, unless you want to change to shim under buckets or shimless. the gen1-3 GE all pretty much have the same head CC so get pistons to suit which ever compression ratio you want. gen1 is 9:1, gen2 10:1 gen3 10.3:1 or get a set of wossner forged pistons for 12:1....LOL
I wont need pistons, just new rings. Ive taken the head off the car, ots sad too see how much chemical gasket has replaced the proper gaskets ;( who ever rebuilt this engine obviously wanted it to be cheeeeeap! So for things like gasket sets, piston rings etc should I be searching for a 3sgte gasket set not a 3sge set? Same for piston rings, would the 3sge rings fit fine? Cheers
Heres how tvis lines up on the acis head. The butterflies won't even completely open unless you port the head.
you could always go like rev and get the lower intake mani (gen 2) and do an itb setup....i think wossner makes like a 13.2 c/r piston aswell? lol
any 3s piston rings should be fine. gasket set you need gen2 3s, the only difference between 3sgte and 3sge would be the intake manifold gaskets. are you going to fit the gen2 3sge manifold? i highly recommend you do. fit a 0.8mm cometic HG for the gen2 3s.
