that plug is an EGT sensor i believe, but im not positive so hopefully someone else will chime in on that.

its a temp sensor for the cat. you can leave it unplugged, it wont throw a code for it.

Just a few pics to coincide with my last update...

Are there any pics/videos of things anyone would like ,e to cover to make my experiences here more like a how-to?

I would still change the timing belt / tensioner / pulleys. Presure2's car had ~34k & mine had ~55k and they both crapped out (they were both '95 I believe). Do it while the motor's out. I'm still waiting on a tensioner from tcbparts.co.uk because lithia toyota didn't have any in stock (mr2 guys grabbed 'em up)

yea deffo do the timing belt and NEW tensior while the engine is out...i tried to do it once with it in the car, and never again...lol, now i have it worked out where i change out my timing belt whenever i do a clutch job !!!!

Does anyone here know where I could find the repair manual for my model engine? I'm considering rebuilding the whole damn thing. I don't know how many miles are on the engine because the shop i bought it from sold the gauges before I bought it, and none of them could "remember". Its guaranteed under 60k, but I like facts...not guarantees. The motor itself is very clean inside and out so I'm willing to believe that promise, but with a rebuild I'll know for sure.

*UPDATE*

Well I got several things done today. I started tearing into the wiring on the st205 frame so that I could teach myself where/what the wires that are involved in the conversion to the 5s need to go. I learned a lot! When I'm done I'll try to make a really detailed how-to on the wiring. I also removed the transmission from the engine. Doesn't seem like much, but both are equally time consuming.








Can anyone tell me what sensor this is in the last pic? It was hanging right under where the radiator used to go.

its a temp sensor for the JDM climate control

*UPDATE*

Can anyone say long block????

i cant wait to do what you are doing.

good luck with the rebuild and hopefully you wont have to machine anything and get oversize parts.

PM me your email...I'll send you the pdf repair manual for the 3SGTE and a few wiring diagrams and pinouts that may be useful

Not to threadjack and hopefully not off-post, but im surprised this website dosent have the repair manuals up in a sticky or something....Would be great if someone could host them on this site...i cant because im at a work computer and i dont have access to a computer than would provide the means to do it

I'm not sure it's possible to post the pdf in a thread, but I'm not entirely sure....I was able to find them online, and other members on here...thank you nammer!, are able to post them.

Another update....I'm sure you guys are tired of this! Trust me...I'll slow down once I'm having to save for all the stuff that I'm going to need!

We tore down the engine today, about the only thing left in it are the pistons, crank, and rods. The head has been removed for machining/reworking. The crank will be removed for polishing and balancing, the rods will be left alone, and the pistons will be replaced with 86.5 Wiseco's. Head is going to have a multi-angle valve job done, new engle springs, ats cam gears, and arp hardware.

The head gasket, combustion chambers, and bottom end are all in beautiful condition.

Can't Wait!

Ingenious way to remove a crank pulley (That bolt was reeeelly tight)



Here are a few pics of the bottom end. It was spotless.

no problem..hope it somewhat helps!

Here is the big question. Would anyone happen to have a vacuum diagram of a wrc motor? It all looks like spaghetti to me.

Disassembled the rest of the block today. Everything came out clean and looks great. Wish I knew the miles....must have been very low.

oil squirters. I didn't know the 3s came with those... do they all have em or just the wrc's?

All 3sgte came with oil squirters.
