Uno Turbo - Build Thread!

Hi there guys

Note been here for a while, but back in the Uno fold!

So, here is what i brought, a Uno 60 with a Punto GT engine conversion.

I wasn't really looking for an Uno again, however this was absoultey mint! Never seen a welder, been waxoled religiously, was just too good to pass up...

Anyway, here are a few of pics of from the previous owner.

Pre conversion

and a pic of the engine and conversion, nice low mile 33k engine and box from a crashed GT.

33k miles


Few pics showing how clean the chassis leg's were!

And a few of the pics of how i brought it..

IMG_4290

IMG_4288

IMG_4289

IMG_4291


When i brought it, it had a few issues i wanted to sort, firstly a really unstable idle, and a few bits that i wanted to re-do to my spec. Firstly the fuel system...

This was how it come

IMG_4374

IMG_4350


Firstly, i got a Metal Mk2 Uno Turbo fuel rail rather than the plastic GT one.

IMG_4380

IMG_4372


So, cut off the fittings and TIG welded some AN6 Fittings on

IMG_4381

IMG_4445



I also changed out all the lines to 8mm nylon front to back

IMG_4457


Next i needed to make up a mount for the FPR

IMG_4450

IMG_4452


Next up made up the lines and fitted

IMG_4462

IMG_4862

IMG_4864

IMG_4778


At the fuel tank end i replaced the original turbo tank with a baffled tank. The days of an undertank fuel pump are gone what with the invent of high flowing in-tank pumps

Old tank

IMG_4569

Old vs new pump

IMG_4570

And fitted

IMG_4587

Next up was sorting a pet hate of mine, bad wiring...

Stuff like this

IMG_4373

IMG_4377

IMG_4376


A few before and afters:

IMG_4389

IMG_4388

and after

IMG_4392

Drivers side

Before

IMG_4446

After

IMG_4447


Next up was the engine loom, i wanted to clean up the engine bay, move the ECU and relays into the car and make it look clearner

Here was the loom before

IMG_4395

IMG_4396


Making a template of the original loom

IMG_4478

Mid making

All new wires

IMG_4482 (Medium)


And done, lovely MIL spec connectors

IMG_4624

IMG_4625

IMG_4626

ECU, Relays, Fuses, and Bar sensor moved into the car.

This was the location when i brought the car.

21231651_10155750779106133_4228195100090642726_n

And after, tucked under the dash.

IMG_4610

IMG_4611

IMG_4612


Sorted a few other bits such as this massive leak..

IMG_4384

And cut and welded smooth

IMG_4387

Also fitted central locking

IMG_4645


IMG_4650

IMG_4646


Next up was sorting the lack of any kind of ducting on the intercooler and oil cooler, seen the difference a well ducted design could make on my Supra so figured i would fabricate some up.

Before, you can see the gaps all around where the air would escape

IMG_4659

IMG_4660

TIG'd up some ducts from aluminium

IMG_4667

IMG_4669

IMG_4668

Oil cooler

IMG_4688

IMG_4685


New ducts and stainless hardware

IMG_4689

IMG_4691

IMG_4690


IMG_4693

Much better, now the cooler will do something!

IMG_4779


Next up i wanted to make an AFM mount as it was just floating about, so...

IMG_4707

Picks up on original mounts

IMG_4709


Also made up a cable mount

IMG_4714

Also TIG'd up some new boost pipes to replace the original mishmash, also changed the filter to a stock air filter housing

Before

IMG_4288

Making the new pipes up

IMG_4698

ICV Spout

IMG_4700

Swage the ends

IMG_4703

IMG_4701


Fitted and done

IMG_4705

IMG_4706

IMG_4771

IMG_4775

IMG_4778

IMG_4777


Last job was fitting a light grill i got from italy along with Mk2 Sideskirts

IMG_4718


Next a nice simple thing, getting rid of my old knob as it was a bit blue for me..

IMG_5249

Nice little carbon number to replace it

IMG_5251


Next up was to put a proper Turbo boot on, this is the one that come with the car, looked great but prefered the turbo look

IMG_5385

Weight of the stock metal boot

IMG_5387

Weight of the new fibreglass turbo boot

IMG_5388

And fitted

IMG_5389

IMG_5403

Much better!

Next up was fitting my new boost controller, using the original clock location

IMG_5404

IMG_5407

IMG_5410

Perfect fit!

I still wanted the original digital dash boost gauge to work, so i used the original MAP from the Uno Turbo ECu with a 5V step down power source mounted to the back of the clocks

IMG_5455

Cut down

IMG_5456


And fitted

IMG_5482

IMG_5483


Next thing to replace was the original black carpet with a red turbo item

IMG_5437

Stripped out and cleaned the floor and protected

IMG_5438

IMG_5440

IMG_5441

IMG_5443

IMG_5445

IMG_5446


Above you can see the original sills, the previous owner regularly waxoyld it and you can tell... no rust!

Now thats a carpet!

777B7CDF-CDB2-4ADE-AE3A-96D24E52882F

While fitting the carpet i decided to add the turbo door and rear cards along with electric windows.

This is how the cards were before...

IMG_5562

First up was putting relays in each door, made up a little aluminium mount

IMG_5586


All fitted and wired up

IMG_5559


Turbo door cards, electric motors and rear cards fitted

IMG_5594

IMG_5597

IMG_5596

IMG_5598

IMG_5599


And also fit my new clutch slave as the old one started leaking.. new braided stainless line too...

IMG_5535

IMG_5538

IMG_5471

First the Speedo stopped working! Looks like the original Sharp optical sensor had started to break down

IMG_5613

So replaced with a modern sensor, was very tricky!

image1

Next up was a wheel change, got some Strada 14" Speedlines

IMG_5876

IMG_5875

This is how they come back

CF8F002E-745E-4518-938B-E3B708DCDA21

IMG_6094

Next up was to change the rad, i want a 50/50 split with the intercooler. I looked at a few options but in the end went with a 4 core 60mm thick Civic radiator.
So, here goes...

Stock rad

IMG_5946

As the radiator was rotated 90 degrees i needed to split the radiator flow path, so gap cut

IMG_5975

Plate slid into the gap

IMG_5976

Welded up

IMG_5980

Temp switch bung welded in

DF934471-16FE-4D3E-80BD-D6D6CB60A458

Mount added to top to connect to slam pannel

BCEBC23B-880A-44EB-B9C1-AAC557611DE2

Bottom rad hose fits perfect

IMG_5991

Top rad hose needs some work

IMG_5992

Made a custom top alloy rad hose and added an outlet to the top of the rad

IMG_6123

As the rad was moved right to the passenger side i needed some very small trimming and wanted to push all the air through the rad

Trimmed up

IMG_5993

TIG welded in place

IMG_5998

ground back

IMG_5997

Primered

IMG_6002

and painted

IMG_6018

Radiator wiring done, all contained so a direct plug in connection

IMG_6116

And all completed!

IMG_6136

IMG_6133

IMG_6132

IMG_6131

Here you can see the area left for the intercooler

IMG_6139

Last mod was a little anti social...

Welded a T into the downpipe

IMG_6049

Welded in

IMG_6058

and fitted

IMG_6061

And done

thumbnail_image2

thumbnail_image1

First up was changing the rear bumper to a nice Mk2 one..



Then i had to take a look at the brakes, they were pulling to one side and really needed a stomp to get them to work...

Soon found out why! Pad's were welded in place with rust!

IMG_6359

IMG_6363

Stripped the brakes off cleaner re-painted and new pads

IMG_6358

Much better

IMG_6403

Then i fabricated a new clutch pot as the old ones look nasty

Old

IMG_6341

New with AN4 Lines

IMG_6353

IMG_6354

Next up i wanted to improve the OE airbox as the pipe sizes are tiny and i will eventually be doubling the power

So fabricated this alloy case and s2000 paper filter with ducted inlet from behind the light. This way i get lots of cool fresh air and it allows the engine to breath

IMG_6453

Here you can see the large 3" inlet pipe to the sealed airbox, little perspex window is to make sure nothing gets trapped in the box, 4 bolts allow quick removal and changing of the filter. This

all fits in the stock battery tray so no mods to the shell needed.

IMG_7195


So with the new airbox in place i now had to find somewhere to fit a battrey. Didn't want it miles away in the boot and no way was i mounting it inside the car. A few years ago a cell went down in

an old car i had and started pumping acid into the cabin of the car... not a great experience...

So here is where the batt was, where the air filter now lives..

IMG_7078

Then i thought, there is some space below the battery tray!

So...

Here is the replacment

IMG_7073

IMG_7072

New mount i made

IMG_6857

IMG_6859

New location

IMG_6861

IMG_6862

painted and foam to protect the batt

IMG_7070

IMG_7071

In place

IMG_7075

And new leads fitted!

The leads are all stock Jaguar parts for the battery and required no mods, i also get the benifit of a fuse which the Uno never had. The only change was crimping new terminals onto the Uno starter

leads

Looks OE too

IMG_7071

IMG_7077

So next up i wanted to make a bonnet lifter rather than using the stay all the time

Simple plate that slides into the reinforced section of bonnet to spread the load

IMG_7008

Then a mount bolts onto that

IMG_7010

Here you can see the parts

IMG_7003

The long part bolts in the original airbox mount holes so no holes need to be drilled

The ram is from a Mk4 Golf Bonnet

IMG_7012

Another small mod was finishing the rad setup, i had made a temp top hose out of alloy

IMG_7080

Howver my new AN20 fittings arrived so i welded threaded bungs onto the rad and thermostat and made the new hose

Big!

IMG_6584

IMG_7125

IMG_7127

With the theme of AN fittings i also wanted to make a catch can

So made this tank, here is the inside showing the deflection plates and twin filters

IMG_6778

Fitting welded to the original breather

IMG_6781

Bolts where to the OE air box went so no holes (theme starting here lol)
You can see the drain at the base

IMG_7011

Made the lines

IMG_7189

IMG_7191

IMG_7190

Next on the list is the header tank, hate the big plastic OE one shown here

IMG_6453

So been trying to learn some CAD, made these 2 files over a few evenings

IMG_6570

IMG_6612

Sent them off to a chap with a 5Axis CNC Machine

And these come back

IMG_6822

Fabricated a tank and welded it all up with AN fittings

IMG_6845

IMG_6846

IMG_7079

Last item which is still a work in process is the inlet manifold

Currently my car has the stock Mk2/PGT type

Here is an old pic:

IMG_6131

So, i wanted the better looking Mk1 Manifold but they have a really old odd fuel injector setup, also no spot for a ICV and just need modernising in gerneral

So a stock old Mk1 Manifold

IMG_6366

Here you can see the old style angled injector mounts

IMG_6367

First job was to smooth them out and remove the old mounts

IMG_6406

Both sides done

IMG_6407

Next i tackled the throttle itself. It has no location for a Punto GT TPS and with my future power goals i decided to go for a 57mm (i think) Coupe 20V Turbo throttle body

So, cut off the original

Here you can see the coupe size vs stock!

IMG_6409

IMG_6466

Needs a bit more taking off the stock manifold

IMG_6467

Machined some more out

IMG_6469

IMG_6471

Then welded the new coupe TB flange and also new injector bungs for modern style injectors

IMG_7103

IMG_7113

Started mocking up the rail also, needed some more work to get it bang level but needed to get the holes in place first

IMG_7128

Next up was the throttle cable, needed a new mount for it and i also wanted to suppot the inlet manifold like stock

Made this mount

IMG_7187

Goes here

IMG_7192

and has a step for supporting the manifold

IMG_7193


Test fit

IMG_7179

Quite a bit still to do on the manifold but nearly there... The reason the TPS is facing up is due to the ICV height. Normally the ICV would be straight up but there is no space under the bonnet

hence the TB rotation.

Right next up was adding the PGT Heatshield to the Mk1 manifold

IMG_7209

IMG_7210

IMG_7213

That should help

IMG_7214

Next drilled and tapped the servo fititng to take an AN fitting

IMG_7243

IMG_7244

And test fitted the fuel rail mounts i had designed, these pick up on the original inlet manifold


IMG_7352

IMG_7398

Also designed a new rocker cover

IMG_7399

All that was left was to paint everything up and refit!

IMG_7460

IMG_7464

IMG_7465

IMG_7466

IMG_7467

652486C4-C40C-4300-8FEC-9021A35FD379

IMG_7470

IMG_7471

All was going well!

Then...

IMG_7580

IMG_7591

Seems when the previous owner changed the headgasket the front row of bolts were either left loose or backed off! The bolts were spinning when i removed them!

New Payne Gasket and Bolts

IMG_7660

Also took the checked the cam while it was all apart, and it seems one of the lobes were worn

IMG_7633

So i purchased a new Kent Fast Road Cam!

117715408_1184049468637512_2615549677328085204_n

117644035_618733512107272_4780055688313382112_n

Clearances

117818616_343312560169637_4734051037393991324_n

Meausring old shims

IMG_7654

Working out shim sizes

117843743_349823576419308_4090216532369945941_n

New cam in and covered in assembly lube

117744902_921643884998886_8818175929095699843_n

Engine was really clean!

IMG_7659

All back togther

IMG_7466

Back to daily duties!
