Team Arctic - Project Polar Bear
The Storey Goes . . . .

One that was a young lad who had a lovely Starlet that never broke and he loved it to pieces, then one day he saw an MR2 for sale and fell in love with it and decided that an MR2 would be his next car to keep with the Toyota. . . and eventually he bought the one he fell in love with as it came back up for sale.

The car has some plans not many, the main plan is to enjoy!

Turbo Timer,
Dual Exit Exhaust,
Charge Cooler/Uprated Intercooler,

spent 12 hours yesterday and half hour today, had to stop because i dont have the correct size torque bits

im quiete proud as someone who works out the cost of building and organising building conrtacts i have no training etc, ive never tried anything like this before. I mean its been fun and im learning but bugger do i get really stressed sometimes :lol

i know whats taken so long would take some people about 2 hours but there you go learning is a curve. . . also ive labbed in bags all my bolts and hoses so i dont forget where i get on :lol

anyway BEFORE


ATM

I GIVE YOU HEAD

nice and healthy




er Pistons another matter :evil




Piston 1

Piston 2

Piston 3


AND Piston 2



as you can see the Piston has a chunck missing but the bore seems good.

Next is to remove the piston and check if the bore is as good as it looks, if it is regular sized forged Pistons.

and then my xmas present from me to me

had a little pull apart today, main hold up was i need a torque gun for the bottom pulley

my old clutch



not sure why my crank has a S on it?


bottom pulley has a few notches out of it? and my bolt is a tad chewed? can i just use any old bolt of the same size? and do you think i need a new pulley?

and the reason for all of this? the piston

whacked out the micrometer today

Piston Diameters. Summary: All within 0.001" (0.0254mm) of manufacturers measured specification. ~ Perfect!

Piston No.1 Critical dimension: Taken at 0.5" (12.7mm) from base of skirt (i.e. bottom of piston.)
3.3925" (86.1695mm) This is exactly the dimention that the manufacturers report states.

Base = 3.3935" (86.1949mm)
Mid. = 3.391" (86.1314mm)
Top. = 3.358" (85.2932mm)

Piston No. 2 Critical dimension: Taken at 0.5" (12.7mm) from base of skirt (i.e. bottom of piston.)
3.393" (86.1822mm) So only 0.0005" (0.0127mm) larger than spec. i.e. ~ virtually nothing!

Base = 3.394" (85.207mm)
Mid. = 3.391" (86.1314mm)
Top = 3.357" (85.2678mm)

Piston No. 3 Critical dimension: Taken at 0.5" (12.7mm) from base of skirt (i.e. bottom of piston.)
3.393" (86.1822mm) So only 0.0005" (0.0127mm) larger than spec. i.e. ~ virtually nothing!

Base = 3.3925" (86.1949mm)
Mid. = 3.391" (86.1314mm)
Top = 3.358" (85.2932mm)

Piston No.4 Critical dimension: Taken at 0.5" (12.7mm) from base of skirt (i.e. bottom of piston.)
3.3935" (86.1949mm) So only 0.001" (0.0254mm) larger than spec. i.e. ~ again, nothing!

Base = 3.3925" (86.1949mm)
Mid. = 3.3905" (86.1187mm)
Top = 3.3575" (85.2805mm)




Update of some painting

Subframe painted


Injector & other items


Rocker Cover with new oil cap

) )


THEN IT WAS BUILD TIME











few random pics

i went last night to my friends workshop where the Emerald K6 ECU is being installed and is to be mapped and it was deminstrated that the car runs

This is how she sleeps tonight atm


The engine has been rebuilt to its full potential

the car is hitting about 16psi but doesnt hold so i have to adjust the actuator on the turbo

the car has been mapped on the Emerald Stand Alone ECU and works lovely

anywho graphs do the speaking



and how she will sleep from know on in her new home

pictures since the rebuild




more progress ongoing and ill see you on track

(sorry for the pic heavy dump if you dont like )

Quote :

Driving home from shell and it broke

Goes without saying really lol. Was a good read.

So apart from the charge cooler, pistons & rods the engine is standard? Im impresssed with 325bhp from the emerald ECU. You say its only running 16psi? Im running around 17psi now but without a re-map so you know what im thinking lol.

Where did that piece of piston go, and how the hell did it not damage any valves, i think god is on your side.

good write up, looking forward to seeing more of this thread

some of the piston was still held on the rings and came out the piston the rest was burns off,

the head was rebuild but the valves were kept.

i also did the balljoints last week and got all the Geo set up so she is lovely know, back on Dyno tommrow to do some tweaks to the cold start on the map

tbh i have loads more pics and there are some minor bits missing from the story such as an oil leak but that was fixed etc

Plans are single exit Apexi Hayabusa exhaust within next few weeks and also a new TB Developments downpipe.

Future plans are Toms Rear Bumper (picking up tonight) , Skirts (undecided), border bonnet (at a mates) and border front.


any questions please ask.

I love this car the right car in the right colour with the right wheels epic thread nuff said

Interesting, after my 205CC is fitted ill be down the RR see what its running. Im guessing around 290ish @ 1.2 bar so if it comes back healthy l might be tempted to ask the question reguarding having a stand alone and re-map in the future.

lovely car mate, i must admit...a little bit comes out when I see forged pistons

oh and yeah I want a standalone

also picked this up friday

Looking forward to the completed pics

wont be for a while yet, got it cos it was a local bargain so snapped it up.

target is toms rear (got), toms skirts, border bonnet (black) (need to collect from mate) and border front bumper.

then may powdercoat wheels black or green or something not sure yet

changed plugs at the weekend and got rid of a minor misfire as one of the plugs had cracked

also

picked this up on the net for £60!!!!

so fitting at the weekend,

Apexi Habusa + Bung





also bought some slim nuts and helemet which i have sat here.

Wow... what Db is that exhaust suppose to run!?

That Habusa is a bargain!!

christ 60 quid, you lucky git!

as said though can't wait to see the bumper on, saw that up for sale on IMOC.

Great looking mr2, i think it needs a TRD air feed or whatever its called 8-)

A toms scoop? Dont like them myself though tbh.

Think they are abit Marmite me personally I think they ruin the lines of the car

Yes thats what i was talking about, well im more function over form so...
We cant all like the same right?

exactly world would be a boring place if we all had the same ideas/opinions

i dont like them, dont mind the bomex ones on a kitted car

anywho it arrived




the dB on this exhaust is suppose to be mad loud, but i have a bung and wire wool so going to do some test over the next few days.

also watching a HKS Silent Exhaust i may pick up if it goes for the right price.

any pics of the apexi fitted mate?(not on your car I know) curious to see what the look like as I've only seen pics of them off the car.

if your planning to do trackdays quite often then the HKS would get my vote.

trackday is booked for 2 weeks time mate

get a pic of it fitted tomorrow

ooooo where you going?

Wheres it booked mate

Bedford Autodrome guys

this was my saturday morning -

so here is a before picture



heres a during



and after




i then i removed this


then it was this



do admit that i prefer the dep two looks, but the sound of the Apexi is awesome, then with the bung it really is quiet

happy with it then...must admit the single exit looks more JDM if you know what I mean, Trust me mate you don't want to admit owning a Departure 2 on here I made that mistake lol

Ah this is why I want a single exit for my mr2.

Looking good mate

went to bens work today just to balance my wheels and put the new nuts on. . .

found out that 2 of my sliders had seized so after some work they were fixed,

then after washing ben convinced me to polish it here are the results (also a new sticker)

Clean

Enjoy Bedford!

Very clean. Love it mate!

and the next day the turbo went bang and the car turned into a smoke screen,

so 1 week to locate turbo or get mine rebuilt lol

Car looks good! Shame about the turbo...perfect opportunity for a larger one though...every cloud has a silver lining hey!

i wont be able to get one in a week i dont think, the only turbos atm are big ones which would need bigger injectors etc so your talking £1000s really and i cba

also there 500-600bhp turbos, engine will take it but i wont. id kill myself

so its either ct20b a hybrid or if a cheap Garrett GT28 comes up ill have that

seems like im going to borrow a ct20b off a friend for the track day

and most likely to send off my ct20b to be rebuilt with a steel centre rather than ceramic, may change compressor etc but think itll be mega £££ so prob wont bother

Bad luck with the turbo, at least you've been able to borrow one for the trackday. Looks mint in the pics, really like it!

Bad timing for the turbo to let go but lucky your being saved by a mate.

Since you have a forged engine to take the extra power it would be ideal if a used larger turbo kit came up for sale.

took the turbo off today and cant understand whats wrong with it

looks perfect

gutted it went mate, it's going to come to all of us at some point!

dunno where it went lol!

went to Staceys last night and removed her turbo

so my passanger seat is powered by a ct20b atm
