Mr2 + 3 weeks ownership then piston melts thread!

ahhhh cool, hers is off the road atm isn't it? remember reading she had problems over on the TB forums

bearings went, so engines out and shes collecting parts for the rebuild, shes already running HKS pistons and Eagle rods so just oil pump, water pump, bearings etc etc

Do the mr2 turbos not suffer after a bottom end failure? A fair few of the Jap tub stuff does which is why i ask

It happens but not a common problem. Largely down to how well its being serviced. More common is for the ringlands to fail.

as Adam said its more commonly ringland failure as per my thread thats what went on mine,

the turbos have a slight weekness due to the ceramic insides, the celica jap imports are ceramic also, although the celica gt4 uk models have steel shaft etc. this is whats just gone on mine.

also bought this new toy, wont be fitted and mapped until after the trackday thou

Useful info about the UK gt4 didn't know that.

What turbo is that and what sort of power you expecting from it?

T05 16g with blitz downpipe hoping for around about 350+bhp with a smoother graph

the ct20b run out of puff at about 5-6000rpm and this should just pull straight through

and the lord said let there be boost!

good work!

working again

so got it working and running and set the boost up to 1.1bar and BANG!

the shaft snapped and the exhaust compressor wheel went missing again! this was yesterday

so today i missed my trackday

feel really gutted, i have one day holiday booked today and that was today was really looking forward to it

spent today stripping it back down and the oil ways are free so im confused

Oh dear bad times mate! Something definitely doesn't sound right with it!

i cant make sense of it, my actuator was leaking so thats one theory the other is just two bad turbos

Gutted for you mate

bloody hell, was this Stacey's turbo?

seems very odd, did it go while hammering it or just regular driving?

its Staceys turbo

i hit full boost 3 times and it went bang

If you ever needed an example of bad luck this is it!

Hope you get sorted and running with the new turbo soon mate.

weekend ill have it with 0 bar and itll sit for 2 weeks then itll be dropped off to be mapped again to 1.5 bar, but ill be restricted by the injectors

Was talking to my dad about this last night. Have you got cooling ok (oil or water....whichever the 2 uses), just wondering whether the turbos were overheating and breaking?

They are both water and oil cooled on the 2. I guess an oil line could get blocked.

oil way was clear so was water, they werent overheating as didnt get hot enough when they went,

fitted the td05 although the braided oil feed was leaking so its had to go off to a hydrolic place to get a new one made up with 2 Banjo bolts rather than the compression fitting that was leaking.

following some notchy gear movement i ordered some upgrades from tim and this is what i found


so tight and round bushes. . . no


replacement done



not driven it yet as been pottering around in the mx5 while ive been working on that. so will see how it goes

Well dropped her off Friday night for mapping on Monday
She sleeps with a nice cars






It's also handy my mapper is also One of me best mates so we had long chats about the car while at snett on Sunday watching the mini migs race

Mapped with the toggle switch done

Set it up so when on my High Map a Green Light comes on the dash to make me aware that im not on Eco

Map 1 - 340bhp @ 1.3 bar
Map 2 - 300bhp @ 0.8 bar
Map 3 - 223bhp @ 0.6 bar

all can be changed via a toggle switch as i drive

Injectors are maxed so that would be next thing, mapper recons i may see 380bhp with larger injectors

Has some extra things on map 1 including dumping some fuel on the overrun to keep the pistons cool in engine cooling, also either retard or advance the ignition i cant remember to increase engine breaking, all sorted for track conditions

Good work mate![u]

Is that an Emerald 3D ECU??

Nice figures.

Emerald K6 Ecu mate,

Emerald K3 also had the ability to do the 3 maps thou

Nice bet it must drop some good pops/bands during map 1 overrun?

find out, havent picked it up yet

he had a tiny bit of work to do in the midrange and was going to play a bit more to increase spool time today thats why i didnt get print offs

Couple of crates of Stella + 2 boxs of cigars =

Good deal for that stuff!

Ill give you 3 crates of Stella and 3 boxes of cigars for the above lol

Nicely done, when you said you were trading in Stella I didn't realise how little!

Update clean the bay up with some powdercoating and painting

then resealed the sump as it had a small oil leak! bloody thing wish they just made a gasket instead of having to just gum it up! but that fixed it.

then figured out my car idles funny and stuff due to the fuel relay, Mr2 due to the large injectors i imagine. run 9v to the fuel pump on idel then its up to 12v when you put your foot down, which was a minor issue with aftermarket ECU but is all sorted know any maybe even more power. being mapped again atm to suit the constant feed of the power to the fuel pump.

bigger injectors and fuel rail still sitting on the side

50/50 if im gunna sell it atm.

pics of clean/painted bay

during

after

That looks really smart mate!

so new exhaust which means i know have 3 in total at the moment,

Mongoose, trying to get my dB down so i can use it on track

got it for £46 and a 10min drive to collect. listed on ebay as "Mr2 Spares" lol bad description win

not got a pic of the exsact one but its this style.

been trying to ask people on here what dB they run but noone replies



other plans include tidying up some wiring on the car, new fuel pressure regulator and a 3 bar map sensor.

also some winter mainteance, new coolant, repair a tiny oil leak (maybe put on smoke machine), repair/new dump valve, check all suspension etc.

maybe buy coilovers at some point

How much was the ECU mate?
