Yes im toying with the prospects of adding a turbo to a 100hp. Has it been done by anyone!?
 
1.4 T-jet is the way to go, been done many time

There is a conversion kit

Not worked out any figures for the 1.4 16v

The 1.2 60hp is limited by the sort duration low lift cam, already high compression and stock ECU

A modest 10% max approximately

Most of the time your diving around between the 20-40 bhp mark uping it to 22-44 isn't going to be noticeable

I had the 60 and 69hp versions at the same time, they drove the same except right at the rev limit

Turbo charging and super charging has been done, seeing the cost involved and no Dyno print outs, I suspect the result were disappointing and only done for YouTube views

There's also the mini Supercharger that could be adapted!?:censored:

Thats not even a bar my T4 goes to 12 psi and thats a Diesel. I dont really know anything about Superchargers apart from they work better low down.

Im all ears if someone wants to elaborte.

To me low down is were you want the power coming in. Some sort of Boost control would be a must. I wonder how much metal is on the standard 1.4 Piston top. Because it could be skimmed, or reworked. Maybe even the fiat 500 1.4 Abarth pistons might go in?
 
Turbo and mechanical superchargers run low compression pistons because "normal" compression will cause the ECU to cut power to avoid the engine blowing holes through its pistons.

Diesels inject fuel into the hot compressed air. A turbo releases engine potential that can never happen with normal aspiration. A turbo diesel will often have a lower mechanical CR than a normal aspirated. It allows more boost to be used. But the CR difference is less than you'll see in petrol engines.

Im not after mega Bhp. Im after a nice low down punch up to 70 miles an hour. Not much point having anything more these days with the amount of cameras around. :censored:
 
Has anyone done a Fiat coupe 20V? :censored:
Not as far as I am aware

The dash gets the rpm, engine coolant, milage check from the ECU through the body computer

the reason the 1.4 tjet from the bravo (up to 330 bhp tuned) works nicely is they talk the same network protocols, so you can keep the same dash, and it has the same bolt hold for the engine mounts

Going a different route your left with sorting the milage. The ECU, body computer and dash have to match, rpm, temperature which are all sent from the ECU via the body computer to the dash,, mounts, gear selector drive shafts on


Nothing unsurmountable, given enough time money and skill

Multijet puntos used to be drag raced at over 500hp
 
You can't turbo or supercharge the standard 1.4 to make any noticeable difference, regardless of what YouTubers say, the compression ratio is too high

The compressed fuel and air will ignite before the spark

It's right at the border line of being possible if it had direct injection, and very careful tuning, but even then gains would be very limited

Fiat put in a stronger better balance crank, stronger flywheel bolts, different cans, better cooling, lower compression

Engine parts are expensive, I like rebuilding engines, but haven't done one for decades, just the pistons, rods and rings are over a grand, it makes more sense to swap the engine, your old engine is worth £300-700 if it's running okay

My Engine and Gearbox, have 106000 miles. Passed the Mot with good emissions. Gears work Lovely and drives lovely. Think ill definately be doing the Tjet(y)
 
I like building engines as well i rebuilt my Renault 5 Gordini turbo engine 3 times :rolleyes: Before i stuck a standard gordini in it. Use to take up my weekends. My Axgt Mk1 had the Saxo VTS 16v init and that was fun.
 
Follow this guy on facebook


He developed the interface everyone is now using

He also very kindly post the instructions on GitHub for everyone to use free of charge

If your good at electronics it's possible to hard wire your own, but a suggest purchasing an adaptor as it plug an play

A multijet would make a good project car, the 1.3 has been swapped for a highly tuned 1.9 @ 500 BHP on the drag strip in other fiat models, I haven't seen a panda done, remap 1.3 with the 1.7 turbo unit fitted is as far as I have seen anyone go with the panda

But as long as it full of clean oil 300nm would be a more sensible upper limit for a daily driver

And puts it on a par with the standard rs cosworth

... A turbo diesel will often have a lower mechanical CR than a normal aspirated.....
I find that difficult to believe, normally aspirated typically ~9:1 typical diesel ~20:1 seems odd that these values could be swapped around. Could you elaborate further with a real example of mainstream passenger vehicle? I may be wrong, (I've been wrong before).

Compression ratio of none turbo VW is 23:1

The TDI version of the same engine is 19:1

Pre ignition is not a problem here with a diesel as you are only compressing air, nothing to ignite untill the diesel is add later, but cylinder pressure are, it's reduced to limit the chance of engine damage and blown head gaskets

petrol is completely different your compressing fuel and air

If the compression ratio is to high the fuel and air will self ignite before the spark



And will quickly melt the pistons

There's several way round this, low the compression ratio, inject water, change the fuel

The 1.4 16v engine is not a good candidate to add a turbo to, the 1.4 tjet was a completely redesigned.

Right starting to make sense now. But if you had your own ECU couldn't you compress air then inject mixture!? Just saying like.
This is why my Gordini used to blow up it was a wet carb suck through. Some days you'd forget yourself and over do it! There was a pinking Knock form the engine then boom Masses of thick grey smoke out the back :censored:

However id like a nice reliable 150bhp ish! The Car is already a Go Kart! Tuned for low down punch!

A two stage map would be good wired to the Sport button so in normal its Shopping trolley trip mode and in Sport complete Panadmonium! :unsure:

Another thought but i dont know the ratio's is would the 1.4 100hp box fit. My VTS, AXGT had a 1360gt box on it.

It's not a direct injection engine

Petrol is injected into the inlet port, it's then pulled into the cylinder via the downwards intake stroke, before being compressed

Yes you can add a turbo, as per YouTube videos, but the boost will be so small you will not notice the difference from the driving seat, except physiologically hearing the turbo and dump valve, maybe

Yes you can run a new ECU, inject a 50/50 Water/methanol, add Oil spray piston cooling, pay for Dyno tuning, in the end, it will cost more, and be less effective


Than getting a reliable torque increase from 128Nm @ 4500 RPM to 206 @ 2250 an noticeable difference just from swapping a 1.4 16V to a 1.4 tjet

Plus you will have a better base for any further engine upgrades
 
T-Jet swap is definitely a more sensible option if you absolutely must have more power. But... you lose the 6-speed gearbox (it can barely handle the 100hp engine), and the whole character of the car is changed (I've driven both, and they both have their own merits, but I honestly prefer a factory-spec 100hp for B-road driving).
TBH, I would prefer to build one out of a 1.1, 1.2 or 1.3 Panda and keep the 100hp as a 100hp.

The biggest problem i have found looking at a few T-Jet swapped cars is the amount of heat going on under the bonnet.
(And the "interesting" methods of getting an intercooler of suitable size and flow in the limited space available)

My son's (slightly stalled at the moment) T-Jet swap is going the Pandapter route, using suspension parts from a 595 into a 100hp shell. As part of the build process we ended up with a second T-Jet engine and I may do a lower-tech version into a 2010 Active Eco which has a broken gearbox, damaged wiring loom and some paint/lacquer problems, but a totally solid body.
There's something rather appealing about a "bog-standard" looking Panda with 3 or 4 times the power it should have. Although I guess the wheels will give it away (can't see 185hp through 155/80R13 tyres being a sensible idea)

@Cinq999 on here has a modified 1.3

And is used a daily driver


Of course you could go real stupid with a highly modded 1.9 400-500hp



But that's a whole different ball game
