Just heard from the tuner... bad engine... think i might have to go 5s-gte...

[zoni]

so my 3s is burning oil and the tuner shop doesnt think the motor will hold up on the dyno for tuning. its in rough shape. they suggest i should find a 5sfe block and go the 5s-gte route... that might be nice but such a pain in the ass cause i thought it was all done... and now i dont have a place to work on the car or an engine hoist to take the motor out.

anyone have a 5s block gen 4??

[Mister_Perkins]

i have a 5s block for a 3rd gen. but its the same as the 4th gen. only difference is the displacement is different.

you should post this on http://www.toyotanation.com/forum/35-car-parts-trade-wanted-parts/

oh ........ zoni that is really bad news , my heart with you when you finish the 3s-gte swap with all that lost oh man

[chronoti]

5s-gte would be sick, wish the best to you man

[zoni]

thanks guys... i decided im gonna take the car home and pull the head off and get that to a machine shop for a head rebuild. then when i throw that back on, if it still smokes blue from oil, i might have to go the 5sgte route... but using the 3s crank too so it'd be 2.1L instead of 2.2 and more machining on the crank to fit the 3s rods.

Compression test? You beat the hell out of the engine or something?

[zoni]

no i got the engine imported from japan... dont know the history... but my guy said it looks bad inside.

[PtBaller]

Damn man sorry to hear =(
You need to get your car running so we can have a reunion its been too long my dude!

If you're going to go 5sgte, you're going to have no choice but to machine the crank.
Your valve reliefs will require that you use 3SGTE/5SGTE pistons, which will require you use 3S rods, which will require you to ground down your 5S crank. Unless you want to waste more money and a lot of time getting custom stuff, this is as simple as it's going to get. Well, as you said, you could use the #s crank, but you drop in displacement and defeats the purpose of getting the 2.2L.
People on MR2OC are always looking for 3S cranks so I would sell it there.
I would get a Gen 4 block from a junkyard and go from there.

for some reason, the tuner that is working on my car broke 3 3s blocks while doing his 800+ whp mr2 project... ended up with a 5s block and 3s rest of the stuff, and was OK.. he seems to think the 5s block is tougher than the 3s block. thats why i mentioned the 5sgte in the first post...

keep in mind, im not going for that kind of power... i want around 300 or so... so thats why im gonna try rebuilding the head first and sticking with the 3sgte setup.

[RichieRichJP]

If you're only going for that much power, just source a Gen 3 Camry block. Gen 4 blocks are just for the more serious ppl...
He is right though, the 5S block is tougher than the 3S because the cylinder walls are thicker, therefore, can handle more boost.

On a side note, the Gen 3 may require you to drill out those coolant passages (cost you more money). If you get a +98 5sfe block, you're almost guaranteed to have straight compatibility to the 3S head.

From what I understood of your original post, it sounds like bad rings. What I do not understand is why are you going to get the head rebuilt if that is not the problem? Do a compression test to figure what is really wrong. A compression test, if done correctly can tell you if it is the head, rings or both. A leak down test would also help.

[zoni]

thanks guys... yeah i think compression test is the first thing i'll end up doing...

and rich, yeah if i do go that route, i would go all out, get a 98+ 5s block and aim for like 4-500. and thats exactly what he told me about the walls being thicker. i guess while he was doing his he went through 2 regular 3s blocks then one sleeved and o-ringed and cracked a sleeve on #3 cylinder just like the regular blocks.. then got over 800hp on a 5s block.

[Mister_Perkins]

if you remove the head, why not just re-ring it while the head is off and replace the bottom end bearings? All you would need to do is get a portably honing bit and hone the cylinders out. The pistons will pull right up through the top of the motor... Just saying

[zoni]

excellent idea! i go have a hone and ring compressor i've never used......... haha!
