EP71 turbo restoration project

[Ep71T]

So this is how it begins . It's an unknown mileage chassis and engine project. The chassis is a ep70 2 door 1.0 which at some time in its life was converted to a starlet turbo with an 2e-fte telu? I don't know.. i call it 2e-t

I bought boua couple of months ago and it has been great fun. 

It has been running ok with a little hunt at idle.. and one coolant leak after another .

The brakes where a mess.. so the decision was taken to stop driving it and restore it .

[Ep71T]

I started with the interior to check the condition of the floor etc.. 

So as I take parts out of the car I discover more things to repair . It's ok it's all part of this game. 

Found a decent rust hole at the driver's footwell and a smaller one at the passengers .

I will repair the rust spots and I also plan the strengthen the unibody if I can. I cleaned the area with the rust and used an air saw to trim it. 

Now off to find some 1mm sheetmetal to make a patch for it .

Keep us updated

[Ep71T]

So I managed to find a fender instead of a piece of sheet metal and went all out forging on it 

This is the piece that came out after a lot of hammering . 

And this is the floor with a couple of rivets . 

[Ep71T]

I will weld everything up when I am done with the interior and unibody mods 

Next in order is to remove the wire harnesses out to repair and put them in order. 

[Ep71T]

So this is how it is right now

The rear sheetmetal needs some sorting out.. 

[Ep71T]

Now I need to tear down and inspect the little Godzilla . 

I was surprised how fast it came out 

 

[Ep71T]

The tear down and inspection began.

Looks good so far. Nothing major . I have to measure bores and inspect the cylinder head.

[Ep71T]

First crack lol.. ct9

2nd third fourth ....

All four have cracks between intake and exhaust valve seats

And after soda blasting it for a better view of the crack lol...

[Ep71T]

So I took of the valve seats for a better view of the crack. 

It didn't look any better... so I was tempted to send it of for weld repair but I found a N/A cylinder head in very good shape. 

So who can spot the differences with the turbo head? 

 

[Stu]

Might pay to cc those chambers and work out the difference in compression.  The stock turbo is quite low compression anyway so alittle bump up would be good, just not too much.

[Ep71T]

Thats what i though too.. 

I will use the N/A cam as it has more lift on the big intake valve whereas the Turbo cam does that on the small intake valve. .. 

Now I have to find out what to do with the brand new ct12b I stumbled on.. It looks enormous compared to the ct9 I have..

Is that from a 2jz? Some of those variants have a larger AR exhaust housing so will be very laggy, might pay to compare against the stock unit.

[Ep71T]

That's from 1kz 3.0l diesel

[Stu]

Ah right, I forgot about those ones.  I'd just check out that exhaust housing size compared to the old unit. 

[Ep71T]

It's big..  don't know if it's worth any effort.

I did notice the cartridge is the same.. 

[Ep71T]

Happy new Year All

[Ep71T]

Back to action. 

Valve cover went for a bath on my old dishwasher along with some motor mounts and other parts for a cleanup.  

if you have an old dishwasher try it out.!

I decided to do away with the red turbo logo.. Black on black is my theme.

 

[Ep71T]

Anyone knows where to find the valve cover gasket ? It has a stop production  from Toyota and no aftermarket luck so far. I made one up for now from a 1zr engine and crazy glue 

 

 

[Ep71T]

So what do you think about stitch welding ? Now the car is stripped down I could stitch it a bit.

Which areas do you recommend? Strut towers? Frame rails ? 

[Calum122]

Cam cover looks great!

 

I always use the home parts washer

[Ep71T]

So its time for an Update. 

 

Fast forward 6 months   I have not lost faith yet !!!

The engine is temporarily fitted to figure out turbo location . 

The radiator support was cut and made removable !

The engine bay was cleaned and sprayed where needed .

The radiator was nicely tucked in on the radiator support and as far left as possible. 

 

 

I used the recipe for bigger brakes found on Epic TMC's channel 

So In my version I Used the Opel Astra 256 rotors but machined the hub instead of the rotor and got some single pot Celica TS calipers. 

Fit is awesome .. will see in the future how they perform.  

 

With white you see the part that hat to go .

Sorry for the delayed posts guys..

I left off Nov before Covid19 and now I have already 5k km on the car and some track testing done.

So from the picture mind the ugly blue coolant hoses , I made a chargecooler and used a hybrid coolant recirculation pump and a radiator from Auris Hybrid.

How did you fit the turbo? Was it a straight fit or did it need changes?

Loving this, really quality work very tidy.
