Differences in 3SGEs?

[RS13]

Hi guys,

A mate of mine is looking to replace his '91 ST182 3SGE with a '96 Curren 3SGE, due to it having considerably less kms.

Are there any major differences between the two 3SGEs? I'm sure they must have changed something between the two, and if they have, (say, manifolds etc), would his older bits transfer to the new engine?

Or would it just be easier to keep looking for a direct ST182 replacement?

And on that note, does anyone know whereabouts would be best to try in Christchurch that may have one for less than $500ish?

Cheers!

The biggest difference is the placment of the oil filter to start with, its located down on a differnt pan assembly as apposed to between the alternator area..

If you want you can see on my website some photos of a 3sge from a Toyota Curren and you can see instantly that difference..

Aside from that im intrested myself to know regarding block differences between the 2 as well as between the 3sge and 3sgte.

That first one looks like a BEAMS motor, and I don't think they were in the 96 Currens?
I *think* they had the Gen3 3SGE, which had about 20hp more than the Gen2, and they're still MAP sensor.
I can't imagine there being too much difference. The intake manifold is different though, so vacuum lines might plumb in in different places but I don't imagine it being a major.

Doesn't look like too much different I guess. He just wants to get it back on the road, cheaply.. I doubt he'd want to mess around adapting stuff to fit.

they are a different block, have VERY different sumps, VERY different heads, different manifolds, different electrics and different plumbing.

You could do it provided you use all the ECU and loom from the 3rd gen engine (curren) otherwise I wouldn't even ATTEMPT to go there. There is NO WAY the manifolds etc from the 2nd gen motor can be bolted to the third gen engine.

a 2nd gen 3SGE will normally set you back around $600+gst from a dismantler with a 3 month warranty. 3rd gen motor around $750-850+gst.

Awesome, thanks man.

I have fittewd 3 or 4 Gen 3 engines into SW20's and from experience it would be best to get a complete motor to avoid all the screwing around as almost everything is different between these 2 engines.

Things you will need(tihs is what I can remember)

Front pipe from the exhaust
Water pipe tree out the back of the head
All mounting brackets (You may be able to modify your alternator bracket and use your original one but if its a round plug type I wouldn't bother as they're getting hard to come by)
Intake hoses as the throttle bodies are different
ECU
Loom
Distributor.

There is probably more but its been a while

Good luck anyway

ANyone know the physcial differences between them as far as blocks and heads etc go, not the "bolt ons" im havving some issues wit boost + gen 3 3sge and im trying to accertain if the motor its self is causing the issues.

[Rob]

The head is taller on the gen 3, not sure about the block?

[Adydas]

the head from a gen2 3sgte and a gen3 3sge were about the same so i dont know how that works..

[Rob]

Maybe its just the boss's for the brackets to bolt on that were different then. I remember slotting a hole to go from the engine mounting bracket on the front of the block to the boss on the side of the head.

Also just remembered that you cannot run the gen 2 computer because the Gen 3 has no adjustment on the throttle body for idle so irt will idle high. I tried all different IAC valves and had the same problem
