Helooo,

As most of you won't know, I am fitting Leweys Uno Turbo Guy Croft spec engine into my Panda to make it somewhat faster.

Anyway I have a few questions you Uno guys may be able to help with.

I am building the engine from parts in boxes and so far just need a full gasket set and a set of standard pistons.

What is a good baseline boost setup? Should I run with a stock boost figure untill I can get to a RR and get things figured out?

Also what is the general rule for finding maximum safe boost? Do you just keep going untill you hear/find/see pre ignition?

Furthermore, I am in need of a turbo. The exhaust can mount a Garrett T25 turbo, but I'm a little concerned that due to the low weight of the Panda ( +/- 700kg) it will just have pure wheelspin off the line, so I'm thinking of something that boosts a little later on in the RPM range.

How do people here find their stock T25, I believe from a Saab or something? Not really looked into it properly.

Anyway, just a few thoughts. Any answers appreciated

Cheers

With a healthy engine and T2, the Panda it will be pretty quick!

Yes get it together, make sure its right and work from there. Consider the thought of "future proofing" the set-up once a base line is deduced with standard components.

By that i mean:

Quality air and coolant pipes
Braided oil and brake lines
Bigger brakes (Uno turbo i would first assume)

Some initial things to consider because power is not the issue, it's harnessing it that is the problem and is often overlooked!

Yeah someone also suggested the T2 turbo as an option due to it boosting a little later on than a T25, this is the first turbo car i've played with though so everything will have to be a bit of a learning curve as far as turbo choices and fittings go.

People dont seem so keen on giving Uno tuning tips! haha there must be an inner circle of knowledge

What turbo are you running? Actually, does your Uno have a spec list? I could do with looking at a few decent Uno builds.

Everything under the hood will be Samco hosing with the best routing possible. My intention is to get maximum cooling into the bay, so I'll be having a no grill, a giant FMIC in the bumper and various radiators for water and oil mounted in the bumper.

Yeah I have similar worries about brakes too. I will have to sort these things out as I encounter them though, hopefully I'll discover a full disk upgrade from another FIAT soon.

Its going to be an awesome car though, I can't wait to get it on a drag strip and lay waste to some expensive cars.

I have no idea about times though. 250 bhp in a 650kg car? Whats that like a 13 second 1/4 mile? Plus a bit of water methanol injection maybe even less.

The original 1,3 IHI Turbos are fine up to 1 bar.
ECU can manage boost pressure up to about 0.8 bar.

Above you will need additional fuel injection.
It can be triggered by the max boost protection switch.

I drove a 1,6 Turbo with brainless boost.
It´s like an explosion and not suitable for normal traffic.

See that the turbo matches engine volume.
Oversizing ist not recommended if the engine is not
tuned from intake to exhaust.

We take brakes from the Fiat "Palio Weekend" or "Doblo" 1.6/16 V
For a Panda the 48mm piston/240mm disc will be best.
the 54mm piston/ 257mm discs might not fit into 13" wheels

Hope you´re satisfied for now

LOL! a great way to describe it

Even just with boost cranked up to 1bar on the standard turbo and standard engine, it does come in very sharply. I have an electronic boost controller that I'd like to set up one day to tailor the way the boost starts, reduce the likelihood of wheelspin and probably save the gearbox/driveshafts from a great deal of stress.

For the standard-sized engine, a small turbo will boost earlier and, I think, be easier to tone down for smooth driveability AND fair power at the top end.

Yes, if you´re getting into it, there´s also fantastic options when you
replace the ECU with a KDFI or Megasqirt engine management.
You can run alcohol fuel and trigger water-alcohol injection and other cool stuff like that.
With a laptop or car-computer you can run different set-ups.
You can get rid of the primitive flow-meter and operate a breakerless ignition.
Nowadays there´s people here who sell these devices for only 200 €.
You´ll just have to do the wiring.
I plan to get into that topic next year since I drive a turbo for not to long jet.
If you want to get into it,start reading the MegaSquirt Forum.
Selling here KDFI

The engine is coming with a Cosworth Pectel T2 engine management system which controls 4 injectors, supports twin coil ingition, wastegate control and a few other things.

Im not even sure what exhaust flange this engine has haha It can either mount a T25 or a T2. They might even be the same, I have no idea!

According to the previous owner, the engine had been producing 220 bhp at 1.3 bar of boost. I am wanting an external wastegate setup for a few reasons. Mainly better boost control and the fact I can run a screamer pipe to the outside world

I'll have to get myself a T25, weld the internal wastegate flapper shut. You can buy a spacer which fits in between the exhaust flange and turbo flange that attaches an external wastegate flange to.

Has anyone had any experience of a similar setup before?

Thanks for the brake help though, I'll look into it

This is interesting. Not very often I hear about a Panda upgrade for the first time! We only have the Doblo here. Presume you are referring to earlier 2000 onwards models? Why do you particularly recommend them; do they easily fit on or are a straight swap?

Can confirm the 257 discs won't fit under 13" steel or alloy rims though unless you were using very extreme wheel spacing.

@ lewey
We discuss the brakes because they are bigger than the UNO Turbo brakes.
The thing is that these brakes fit "plug ans play".

I´m not sure about the 240 mm DOBLO brakes , you´ll have to see for yourself

The larger 257mm discs are reported to fit 13" wheels with 8 mm spacers.
But you´ll have to try that in particular.

Here are 54mm piston/ 257mm discs in 15" wheels.

I have a standard turbo and manifold for mk2 uno turbo if your interested? you dont need to upgrade the turbo for big power, 170bhp is achieveable with the standard unit, bigger turbo means more lag which is not fun

I have an exhaust manifold which can mount either a T2 or T25 turbo, I'll find out properly in the new year when i pick the engine up. I would like to achieve 250bhp from this engine.

Does anyone know a good place to get an entire engine gasket set?

Try ebay: http://shop.ebay.co.uk/?_from=R40&_...no+turbo+gasket+set&_sacat=See-All-Categories

Yeah I saw those on ebay. The one at the bottom looks the best but I dont know if its the right set, and cant see if it has valve stem seals.

All the other look like poor quality, e.g - no metal crush rings in the inlet gaskets.

The problem is finding a set that covers the bottom end and not just the head! And I need a set of pistons hahaha

Is he saying that these brakes are a direct, bolt on upgrade for the Panda? Not really fussed about wheel size as I think some 14" wheels are in order anyway, but if the Doblo van brakes fit straight on - im well chuffed!

Not sure if Fiat still do the full gasket kit still, or the bottom kit, but you could still get most bottom gaskets separately from Fiat a couple of years ago

Pistons may need to be second hand or aftermarket. they are the same bore as the mk1 but I think I remember seeing a picture on turbo collective showing that the crown height was different. didn't you get the oversize pistons from the trashed block thers much been said about using the mk1 block instead as people say it's stronger than MK2

I've got a set of MK2 Pistons, only done 40K before the block split,,, Let me know if you are interested? But it beats me why you bought this Job lot in the first place???

Charlie

Well its not really a job lot as such. More like a dismanted uno turbo engine - but with a brand new block and other things that make it quite special.

I bought it because I was getting bored of my current 16v engine and wanted something a lot faster in the Panda.

What do you rekon the cost of OEM pistons from Fiat are? I'm not too sure about secondhand pistons since I'm spending quite a few quid on this engine. I'll send you a PM later anyways

think people have said the o/s pistons are NLA from fiat but do check the std size and let us know

Correct me if I'm wrong mate, but the only things that are left from Nathans GC engine is a standard Crank and Rods??

And whats this about tolerances, before you edited you're last post?

Sorry, I was saying everything is measured and within tolerance, so it's a decent engine to tune.

Things left from the engine? Im not sure what you mean. Everything is there apart from pistons. I'm guessing the crank, rods and head parts are the same as before.
