3sge 3d gen swap help Options

[mi645]

So I have a 99 stock Celica gt I just got a 3d gen 3sge with full wiring uncut I was wondering web I swap this motor do I need to sauter or slice and wire anything or it all bolts in even the wiring?
Also do we use the oem 5sfe fuse box or the new 3sge fuse box?
I'm currently tuning up the motor new timing belt water pump etc.
Motor came with exhaust manifold but no b pipe does the stock 5sfe
Exhaust manifold bolt on? Just for temporary use?
Any advice from anyone please Ive been googling and searching threads but found nothing for 3d gen swap not beams.
What do I have to modify? Do I need to convert a fuel filter or bracket? The fuel lines are uncut on the motor I got only thing seems to be cut is the shifter cables and axels

my advise, sell that engine and swap in a V6. you are in Kalifornia and it will never pass SMOG.

advise #2, read the stickies, all your questions have been answered 100 times before

[mi645]

Id like the v6 swap but I got this for waaaaaaaaaaay cheaper.
Also I have a smog person I'm
Not worried too much also I'm keeping my 5s in case

there is no stickies for 3rd gen 3sge swap only beams. even beams swaps are not stickied you have to dig around. you have to read 3sgte swap threads is what he means. most of your answers concerning basics are there.

its only 20hp difference... and it has easy modification to gain that 20hp anyway.
if u can find me a v6 completed harness with lsd trans and everything included for 400 bucks then ok u got me thinking if not then no thanks lol.

As with any JDM(RHD) motor into your USDM(LHD) celicas, from what I've seen other members do, you need to:
extend the wiring harness to reach the hole in the firewall or
make or use another hole

I'm not 100% sure about the 5sfe exhaust manifold fitting the 3S-GE head in terms of bolt pattern and also clearance under the sump


Have a look at KAOS and czwalga project threads. The 3S-GE swap is pretty close to the beams, but with the need for the white 9,000rpm cluster or modded cluster, but would suggest getting the black 9,000rpm cluster for yours.

I used my stock cluster without a problem.


Harness needs to be extended about 2-3 feet. Around 60 or so wires. My harness was cut, so I pretty much merged a 5sfe and 3sge harness together taking what i need from where. I've made 3 different b-pipes, and broke them all. Damn skid plate is bubbled and keeps coming up and cracking it.

oh man that wiring looks scary! my harness isn't cut so it still needs to be extended? how can I extend it? which wires exactly which part and where should I get the materials? sorry im not a wiring guy lol.
thank you guys! I really appreciate it!.
so the fuel lines also hook up to gt fuel filter?

[Smaay]

im all for doing something different, but i just dont see the gains worth all the work involved. but good luck, A dyno before and after would be really appreciated

[Rusty]

how is it something different? 3sge, beams and 3sgte all came on the ST20# celicas.

[mi645]

Damned the hydraulic tensioner is a pain... Anyways while I was impacting off the cam gears they moved a tooth both to the left web I put the belt back together do I have to worry about the timing or a tooth might not even matter? Since they both moved a tooth back

[czwalga]

The harness has to be extended. There's 6 or 7 connectors where the ECU goes to. 4 go to the ECU the others go to the body connectors. So yeah the harness does kinda have to be extended to go down there. Yeah you could do something crazy to not half to extend all of it, but that would be harder on the brain than just extending the harness.

The part you have to be concerned about is the fuse box area... even if its not cut I doubt everything just snaps together perfectly. Buy the green book for our cars on ebay for the electrical manuals. It's like $20. Well worth it, won't tell you everything because it doesnt have 3sge info in it but you can piece it together.


Wiring doesnt scare me though, and the toyota books have the best electrical schematics i've seen. Nice and colored.

Set the timing, start from scratch. Even one tooth it may not idle.

not over here, hence different. we ONLY got 5S-FE or 7A-FE

[mi645]

ok wll the problem is the motor wasn't set to tdc when the timing belt was removed but it was timed. now is it possible to put the belt back on then set the crank to tdc and the cam obviously will spin with It but it will be a tooth off and then adjust the cam timing? or even a tooth off and the motor will make contact with the piston and valve? hand spun not crank the motor.

[kurt95gt]

If you don't want to take the time to reset your timing the right way now that you threw it off by at least a tooth you might as well scrap the whole project because this shows how much effort you really wanna put into it

[mi645]

I believe u miss understood what I was asking...
I was asking whats the best way to reset the timing...
geeze lol

[czwalga]

A tooth off wont cause cause valve damage. I'm pretty sure the 3sge is a non-inteference engine. BEAMS may be interference, but not the 3rd gen. So no matter what happens your engine should not kill itself.


Just take the belt off and follow the normal timing belt install procedure.

[mi645]

oh I tho it was interference why thank you. that makes thigns much simpler.

5S-FE exhaust manifold will not fit. Had the same problem with my 3S that it only came with the manifold and no B-pipe. Had to get one custom made.

Checked my timing belt replacement guide and the 1st and 2nd gen 3S-GE are non-interference, so one would be led to believe that'd be the case for the 3rd gen as well.
