Hi all,

I just brought a year 2000 MR-S not long ago and found it the engine is really thirst for engine oil.
From my last oil change until now, about 3000km run, I have already top up another 4L of engine oil.
Currently, the engine oil is less than half in the engine oil check stick.
And I also having RPM dipped when my car came to stop from running.
Basically, it will drop to around 500rpm (car start jerking) and return back to around 1000rpm.
Sometimes during iding also, it will dipped to around 500rpm too..
I have since change my spark plug, battery and also clean MAF sensor, idling valve and throttle body.
Every time after I did something (the above mentioned), the RPM become better but the condition will return the same after some driving.
Currently, the mileage has more than 170000km on it.
Hence, I was wondering should overhaul my engine?
and how much roughly it will cost?

I'm also thinking to turbocharged my engine in a later stage if I overhaul the engine, so is it better if I just swap in 3sgte?

Please give some suggestion and idea.
Thank you.

1ZZ-FE engine? IF yes, then I dont have a MRS but just same spec engine. Mine was burning engine oil as well. Less than half
especially if I drive hard for few days. There is once almost no more engine oil. Engine oil was consumed even faster then.

When I thought of overhaul, I was too late but was being advised to do so about a year ago but then since the car still can drive didnt bother. End up gasket pecah and water went into the engine. Couldn't overhaul/rebuild but open up and checked, indeed my piston ring is no longer good condition which is why consume engine oil as well and other parts in the engine.

Best to overhaul if wanna keep same engine. Mine start to consume engine oil also around 180,000 mileage.

If u wan more power then go for a 2zzge swap, is more then enough for a light weight car. If u intend to keep stock then overhaul it n do it ASAP as the oil consume was serious to avoid more costly repair if u damage the internal.

Supra_fanatics,

Is ur engine come out white smoke when it consume a lot of engine oil?
Cos my mechanic friend told me, if piston ring spoilt, should have white smoke..
So just wondering if it could be no white smoke even the ring is spoilt..

I was quoted around 3K for overhaul at 1st depending on what's needed to Change as well later. Was just a rough figure given to me. Mine last time I seen once got white smoke but after that no more, so thought nothing wrong, but then my parts inside is more severe than I thought. But then could be because of the car overheating that melted some of it according to the workshop but piston rings is really bad. Since adi start consume so much oil might as well overhaul bro. If no problem wouldn't overhaul as well. unless unplanned for a better engine transplant than leave it until you have budget to change hehe! :biggrin:

Better than having more serious problem like day line bro mentioned.

Just checked at workshop today.. No leaking.. So confirm is burn oil..
Was quote RM1-2k for labour, parts should be around 3k plus for toyota ori parts.. Estimate roughly 5k plus altogether..
So I guess I should go for overhaul soon.

Ya is around that price...8K for 6-speed manual, + labour and etcs already cost close to RM10K
then later need to upgrade other things like brakes and etcs. At least 12K to be safe for 2zz
transplant.

Maybe swap 3sge if RM5K hehe! Can try ask around how much is 3sge/gte
I heard is around this price. Cheaper than 2zz

But I heard a lot of custom things need to be fabricated in order to swap 3sgte into MR-S.
And I also not sure which workshop would be experience in jb for this kind of swap..

That one not sure, got to find out and survey around if really intend for the transplant.
Maybe check MR-S forums or anything. Not so sure about that.

in there abouts (cost).

but its a whole different engine.

if you intend to turbo the mr-s, a low boost bump shd be ok, any more...well make sure there are spare 1zz engines :)


3SGTE is a beast engine, can easily handle more power. though the weight of the engine is a drawback on the mr-s.

There is one or two mr-s that been swapped for 3S in malaysia, 2zz mr-s about 6, 1 swapped k20a in JB. :)




your 1zz piston rings are toast (which is why the depletion of oil), it happens unfortunately. happened to me before, but on a higher milage. decided to opt for 2zz instead

Hi koolspyda,

Any idea where the 3S is swap?
Although 3s is much heavier, but with the power increase, I think the the weight increase is insignificant..
I'm more concern on the weight distribution since the weight will be more towards the rear.
Maybe the car will tends to be more oversteer?
