MultiAir vs TJet in the Big Turbo Abarth 124 Spider

Today we talk about converting the Abarth 124 to run a TJet engine just like the European Abarth 500. This should fix it all.

The two rods go into cyl 1 and 2. They are there to line up all the pistons at the same height. The two round plug pieces go into the side of the cam box. They slide into slots in the cam shafts to hold and line them up. YOU CANNOT FIT THE ONE FOR THE EXHAUST CAMSHAFT WITH THE TURBO ON! Intake side fits in fine. Also have a look at he intake manifold as the tjet ones have a purge valve For evap underneath. Also if you are thinking about doing cams do it before you put the cam box on, they slide out from the side which in the 124 it will be on the firewall so it will have to come back off just to swap the cams!

[@PistonsAndPetrol]

Cunny Funt pinned. That’s straight useful. Thanks mate. 👍

[@SantarelliPuncake]

Pistons & Petrol I am pretty sure that the cams come out from the back side of the cam box. I maybe be wrong we haven’t done it as of yet in the next few weeks we will be pulling cams out of a tjet but until then I won’t know the answer I’m sure there are people in the community that will know for sure!

[@aurick861]

@@SantarelliPuncake They will slide out to the front of the engine. You still need access to the back to undo the two gearwheels bolts. The cams won't slide out unless the box is off the car ...the valvess would push up on the tappers into the cams and would block the cams from coming out. I've just donee the camshaft replacement a few weeks ago on my T-jet. Thee two cam locking plugs get used togeether wheen tightening the bolts for the gearwheels, aafter that they will be timed together, so only one (intake side) is used when installing on to the engine.

[@abarthcorsa3493]

I’m glad someone is doing this because it’s something I’m seriously considering in the future. I just love the euro engines

[@pfacka]

As far as I understand why Fiat developed Multiair was to get some of the properties of direct injection to enhance emission control and fuel economy. Fiat lately sells almost exclusively economy cars so another not less significant objective was to cut cost. Multiair head is suprisingly cheaper to manufacture than dual cam phasors plus they did not have to deal with high pressure fuel pump, expensive injectors and carbon build up issues (Mini/VW TSI). Kind of brilliant, but not what and enthusiast is looking for. Not to say that these circumstances did not yield some other interesting properties, but it is not what they were meant to do. That said I'm amazed how far you guys were able take these engines.

[@keithwittman4741]

Your Fiat 1.4t projects are on a level like a race team or Carl Shelby to Ford !

[@PistonsAndPetrol]

Keith Wittman thanks!

[@Shoffty]

I can't wait for you guys to put this on! I've thought about doing a T-Jet swap in the future and if everything you guys are doing goes well, I'll have to do it!

[@davidelliott5843]

Fiat have always been very modular. They upgrade components of existing designs and are often backwards compatible. The pins are to set the pistons at 50% stroke. Then you can whizz the cams around as much as you like with no worries.

[@DanHowardOG]

I AM TOTALLY ON BOARD!!!!! Just about to put my dart into storage for the winter so I hope your project goes well so in the spring I can start my own T-jet swap. subscribed and watching attentively!

[@Future5305]

My ideas are speed holes and aa racing stripe. More importantly, I noticed the new hat....I'm not sold on it.

[@IanNubbit]

See. My thing is Multi-Air sounds soooooooo good. The amazing exhaust sounds that it creates is so much better then the T-Jet. I can't imagine loosing the Multi-Air sounds

[@PistonsAndPetrol]

The tjet sounds much better.

[@dobbydabz516]

Pistons & Petrol in my op that’s not true multi air sounds better

[@dobbydabz516]

Pistons & Petrol and it’s popular opinion that ma sounds better than any 4 cyl

[@Azzurra2k]

Man i dig it, Finally the bulges on the hood will match the amount of camshafts haha

[@MrMaxDelux]

Hey... It would cool with a duo tone color, dark bottom white/ grey roof. Ultraleggera rims in bronsch color. NOS, haven't seen that for a long time. No backseat, roolbar, and... Interior like a old classic Mercedes

[@Mara941]

What do you think about Fiat Tipo 2017 1.4 T-Jet 120hp engine? planning to buy one

[@denissarvari7629]

I have a alfa mito 1.4 155 tjet, wanted to put n/a punto cams in it. Hope you will try it. Happy to see tjet project.

[@LorenzoClara97]

1.2 16v or 1.4 16v from the panda 100hp are all an upgrade

[@davidelliott5843]

Lorenzo Clara The Panda 100HP cries out for (at least) another 50bhp. Chocking on a turbo with ported head should do the job nicely.

[@truthwarrior2149]

First of all, thank you so much for the work that you're doing and the knowledge that you are spreading for the entire Fiat 124 community. My question is that you're first turbo swap seemingly went very smoothly and you were able to get some fairly decent horsepower out of that set up. What is different about this turbo swap it has made it so problematic? Is it that this engine in the white 124 is just a dog or is it simply because this is a substantially bigger Turbo and it would be problematic no matter what 124 you put it in?

[@PistonsAndPetrol]

LAW MAN something is blocking oil flow to the Multiair. Its covered in the video. The black car was a good engine and a simple, tried and true 1.4 setup. The white car’s engine was just a lemon from the start.

[@Nebbia_affaraccimiei]

should have asked to MTD in greece. they do all things multiair and Im sure they could have solved this..

[@PistonsAndPetrol]

Nebbia affaraccimiei no. They’re having the same issue with a Punto. I have been speaking with one of their customer. The Punto and 124 ECU’s are a bit different as are North American and European ECU calibrations. They’re not the same as a Punto. Besides, this is not a tuning issue.

[@Nebbia_affaraccimiei]

@@PistonsAndPetrol i never said it was a tuning issue just though they encountered the same problem before

[@PistonsAndPetrol]

Nebbia affaraccimiei I tried to buy a camshaft from them a while back and they wouldn’t sell one to me. They’re not worth my time.

[@operamatthew]

would love to see a t-jet conversion with a standalone. really make the platform worry free and simple.

[@J-Eagan]

Get the supercharger off the E55 AMG’s M113K and put that on your Mercedes

[@JNAMOTORSPORTS]

Did this car ever make 300whp? Or was it ever finished?

[@PistonsAndPetrol]

COVID happened and I haven't seen the car in 2 years because I live in Canada. It's sitting in the USA complete and waiting to be filmed.

[@miralemnermina142]

inb4 he swaps the 1.4t for a 2.0 20v turbo 5tech

[@miralemnermina142]

If I remember correctly those automatic transmissions were very slow and could be improved with some simple tweaks. 4.3 is a good engine but you need to do a lot to it to get a lot out of it. M103/M104 or a turbo OM606 would be far better but that thing ain't bad too. If I was you I would get nice exhaust (including headers) and maybe an ECU remap

[@peteskeet9443]

Very informative. Thank you!

[@jeremystager736]

interesting video. cant wait to see what comes of it.

[@zepts7970]

So will you rev it higher now?

[@PistonsAndPetrol]

Zepts yes 👍

[@diogo266]

You're gonna lose low and mid end torque, swapping to a t-jet head. Multiairs are way torquier. Either way, people in Europe have been porting the multiair bricks to allow for more flow.

[@keithwittman4741]

Right. As I am seeing, Fiat left a lot of growing room, for the future . They eraed on the sides of longevity and fuel economy. Just look at the stock tubro.

[@kidoctane]

I have both......and the real world difference is very little (these are light cars). l prefer my T-Jet over my MA

[@world_zikkurat]

I replaced the exhaust camshaft and got 1 bar 500 rpm early.

[@stevemiller2651]

It's all about the exhaust cam with the Multiair. Change to an uprated cam and these engines are very tunable without the need to force high boost onto them.

[@world_zikkurat]

@@stevemiller2651 I use t-jet

[@stevemiller2651]

@@world_zikkurat I guessed that was likely by your name 😉, I was just saying that the key to the Multiair is the cam 👍

[@joshuajacome8803]

Can someone please explain what practical benefits would swapping to the tjet head will provide? Sorry if it's a stupid question...

[@PistonsAndPetrol]

Joshua Jácome less moving parts which in simple terms allows for higher RPM operation and in the end, more power. Also, less moving parts is generally much more reliable.
