What Gen of 3s-gte engine Photos

It is a 3S-GTE. Maybe a Gen 2/Gen 3 hybrid. Not all of them had a Toyota logo on the valve cover. Here is my Gen 2 valve cover on the top photo. Ignore the COP...that is an upgrade. Your valve cover looks like my Gen 3 with the raised cam area. It has a distributor with standard plug wires. My Gen4 is different with stock COP (2nd pic), oil filter is in a different spot, etc. That downpipe has some serious battle scars. The issue is that all the components on that engine look Gen2 with a Gen3 valve cover to me. It does not look to have EGR. If I had to guess, I say it is a late Gen2 motor (around 93-94) from Japan. My 91-92 cars are early Gen2 motors.

Early Gen 2


Gen 4

OK so longer list:
Toyota Gen3 3S-GTE
Turbosmart boost controller
Weird intercooler pipes, maybe off to a W2A or runs down into the Celica bumper?
There's a lot lot lot that I don't like seeing here. Lots of important parts are just hanging or look not-hooked-up. Does this engine run?
Misaligned throttle cable


Are these mounted to anything?



Emissions stuff bypassed (not such a big deal, charcoal canister, etc hookups)


Catch can not mounted to anything? I think this gen is supposed to drain back to the block somewhere as well. Also factory bypass valve (BOV) just open-air instead of recirculating or filtered


Exhaust manifold and turbo both missing heat shields


Downpipe welds are weird and awful. Also is it touching the fan?


Intake fixin' to fall out of the turbo at the coupler

See this plate under my valve cover breather tube? That is an EGR block-off plate. Does your head have one? Is there even a hole? My JDM heads do not have a hole for an EGR.





See this oil filter location? It is way different than a Gen2. Where is yours?


There are 2 things to take away from my Gen2 block. 1. The oil cooler and filter go where that red tape on the block is placed. 2. When you talk about 7 bolt or 9 bolt, it is just the exhaust manifold. The head is drilled and tapped for either. In this pic, you can see a 7 bolt manifold with unused stud locations in the head.

Ok ok, everyone 😊 thanks for the reply's so far.

Car does drive runs but does have an exhaust leak from down pipe and manifold , surprise, surprise

I understand that the engine is hack job but that's why I'm here, ( swapped 3s-gte in an Gen 7 Celica vs swapped in Gen 6, etc... is different I think)

Would like to repair, make things better.

A couple more pictures

Ok, plan was to clean up wiring, mount loose components etc.. fix oil leaks , distributor oring, oil cooler orings, dipstick o-ring.

Would parts from a gen 3 be OK to order from in your opinion?

Exhaust manifold gasket gen 3 also ?

Plan was to get manifold machined or sand down flat if needed and install new studs and figuire out new down pipe

Thanks

Take off the intake and exhaust manifolds and take a picture. It sounds like that is your plan anyway. The intake ports on a Gen2 are different than a Gen3. The exhaust ports are lower (closer to the deck) on a Gen3 than a Gen2 as well. Unfortunately, I do not have a picture of all the heads side by side.

Here is a link to a youtube channel that I watch. You might get some of your answers here. They have a lot of 3S-GTE info.

Gen2 Intake ports are large and more rectangular.

Took off exhaust manifold.

From google, this motor now looks to be a 1994-1999 JDM 3S-GTE 3rd gen. MR2

Lots of clean up and new seals etc...
Time to order parts!
