i need help about celica gt4 (ST205)

[Adydas]

How do you get 1l of water in ya car.

Oh a st205.. changes things dont it.

[Alex B]

maybe the w/a intercooler shat its self?

[Adydas]

That sounds most likely, i couldnt imagine it Sucking up that much water.

It says via the rain on the road tho, my guess may be a pod filter located in the front bumper or something to that effect.

Boost Plus air located via the front bumper with rain COULD do it.. but still 1l :O

[zzokojoa]

i was driving at about 70~80km per hour and foun the water on the road somewhere on my way up.
I decided to ignore it because I thought that it was a very little.
When I was passing that position, the water splashed upto the side mirror height and the tyres weresinked under the water about half or 1/3 of it I guess.

hrmm

Well my suggestion would be replacing the pistons with some oversized ones and getting the marks in the bore shaved out ( to fit the new pistons ) how ever that wont be cheap and might not work if the marks in the bore are huge.

best bet would be a new engine but finding a ST205 one wouldnt be to easy.. for that matter nor would a ST215 caldina one ( not that i regularly check out pick a part etc ).

All in All not going to be cheap or easy..

[zzokojoa]

my budget is about $6000

and is it possible to the st215 engine into the st205? caldina gtt

[Adydas]

You would need the ST215 ECU also i would imagine.. there for youd need a Manual one meaning hard ish to find etc.. I dare say its doable but
would be awfully expensive. And i wouldnt imagine overly to much gain.

Perhaps the motor would run on st205 ecu but id be suspect of that, plugs into ecu etc.. Anyone else know this?

fivebob should chime in here soon, as far as i know hes looked into it and its a big headache.

Should be able to rebuild for under 6k

[Adydas]

Thats what i was thinking, OR a SW20 Turbo engine maybe a easyer option? but yet again ecu etc may clash and cause issues

Id suggest Rebuild and or replace things.

[Sick Puppy]

Also, apparently the Caldina engine doesn't have the performance of the Celica, does it? I remember reading about it in some magazine or another that although basically the same running gear is used in both models, the engine management and internals are a bit different...

[sergei]

OK, if 1L (!!!!) gets into engine there would not be stractches but BENT CONRODS, PIECES OF THE BLOCK FLYING OFF. I've seen that sort of damage it take 1 sec in the lake to get a "hydrostatic shock".
Water cannot be compressed, in fact it is easier to bend conrods/cranshafts crack block then to compress water. Especially if car doing high rpm (not idle), driving (especially in manual), there is a lot of rotating and moving mass to stop and that energy has to go somewhere, and it goes in bending rods and breaking block.
UNLESS your mechanic is like many arround is full of BS and wants you to pay for his holyday, just because you got some water on electrics and car stalled (or similar cause).

[TRD Man]

sergei, you're quite right. Hydraulicking is not uncommon in rally cars racing through fords but I've not heard of too many cases on the road.
Is it possible that through hydraulicking it's broken the rings and scratched the bore or possibly even cracked a piston or two?
I would imagine you'd have to have been going through some pretty deep water with a reasonable amount of Welly up it to do that.
Most cases of hydraulicking I've seen simply end up with the engine stopping and needing to be drained of water.

Sounds about right. As I'm close by, I've given the guy a call and he's going to call me back tomorrow and we can hopefully work out exactly what has happened and ensure that he isn't being ripped off!

BTW, intake system on this car is stock standard. I just can't see how 1L of water would get sucked into the engine.

Gary you're my hero

to quickly answer the question at hand though, if you need to replace the engine then you can make do with using a short block out of an st185 or sw20 mr2. AFAIK there is no real difference in blocks between st205 or st185. A Caldina one will also work but I believe they're higher compression?

[GT4 20]

Given the (somewhat ambiguous) description, I've got my fingers crossed that it will be a simple case of a 0.5mm overbore with pistons to suit and the reassemble. Obviously depends on what these 'scratches' are like. may even be a quick hone? Who knows. At least I can get some .5 oversized ACL pistons dirt cheap if they are needed so he won't get copped by a mechanic's mark up

Finally got to the bottom of this issue....
A definate case of hydrolock. All 4 rods now resemble bananas and there are cracks in the piston skirts also, probably due to the excess stress from the gudgeon pin. Bores appear to be completely unmarked.
So, in short, it would appear that the following is required -
Replacement pistons
Replacement rods
Re-hone
Main shells

Given the potential for making quite a mess, I think that zzokojoa's engine has come off pretty light. Could have been a lot worse. Anyone have a set of good 3SGTE rods kicking around?
Gary

[Ako]

By some fluke, I do

[vvega]

i have a have a set of rods and a set of gen2 pistons

in fact i have a entire gen2 with a blown big end(shell did not spin so rod is not damaged)

Any word on how that much water, actually got in there?

[GT4 20]

Looks like a very deep 'puddle' + speed
