I have modded my car with new FMIC, SIP and a Blueflame exhaust. But this story is about my new turbo

Last year after attending a track day I saw that the turbo started to smoke a little bit. I went to my mechanic and we both realised that it was time to change turbo.

So what do you buy?? Many people on fccuk buy a Garrett GT28R or RS but I didn´t want to modifiy the exhast too much so that idea kind of disappeared rather quickly

After that I decided to upgrade the original turbo to a GTiR. I was about to contact a local turbo company here in Göteborg when a guy at the Swedish Fiat forum said that he was about to install a Mitsubishi 16T on his Fiat Coupé 20V Turbo LE. I asked him if that was possible. Yes the man who build the turbocharger changes the flange to a T25 so that it can sit on the exhaust manifold. Damn that sounds so good
I then talked to some people (at Volvo Car Corp.) and all said that the Mitsubishi turbo is quit nice. The turbo has slide bearing so if the bearing will break it´s easy to change it. I just thought that the 16T was too small for my project. I went to the company that builds the turbochargers and found out that a 19T should solve all my problems. After a while I made up my mind and ordered a 19T with a T25 flange.

So this week I picked up the turbocharger . It´s TD04-19T (it´s installed in Volvo V70R AWD if you didn´t know) and it has a 360 degrees slide bearing. I only have to cut the end of the downpipe and weld on a new flange. I will install the new turbo in April. In the beginning I will use the standard ECU and GM EBV, FPR and a Gtec2. After a RR session and if everything is okay, I will install a GReddy Profec B spec II EBC. I will then turn up the boost

I hope I can reach 320-330 hp

Interesting, it may be the perspective in the last picture but it does look wide. Hopefully it will fit nicely

Nice project. The actuator looks enormous!

any chance of having the specs of this turbo and its diagrams?
wtf is that slanted cover on the compressor side
oil and water cooled or just oil?

I hope I can use the heat shield after installation

I will get a compressor map and specs for the turbo. Just wait a day or two
Volvo use the plate for mounting the Blow Off Valve.
The turbo is oil and water cooled.

Its what most people with T5s upgrade to as its a simple bolt on to the standard manifold, only things that need to be changed is the downpipe and a remap.

You should be able to achieve 300bhp fairly easily.

Us T5 lot are trying to get away from the Mitsi turbo and in to the Garrett BB T3 flanged turbos' lol.

And I try to get away from Garrett BlackBeast

Hi Fredrik,

Nice to see that you have taken one step further ..., in never ending game .

Yes, with the -19T you will get easily that 300 - 320 bhp out of the engine. I'm not 100% sure, but is it the same turbo than Saito / Italy sells as "SC300" for Coupe.

You will need to change the wastegate actuator placing, because like that it won't fit. The gearbox housing is too close to that, GT28R turbos with original actuators have the same problem.

Keep us posted with the new project .

Here are a bunch of flowmaps for different turbos including the TD04 19t

Thanks for all tips and comments

The first small problem has arrived
Yesterday I held the turbo at the right position. Me and my mechanic saw that the wastegate touches the engine. So we need to make a new bracket and relocate the wastegate.

Today there is a new wastegate installed on the T19 but it´s too hard. I will reuse the original wastegate from TB28, so I can use the ECU + EBV for boost control. Do anyone think there will be a problem?

as per the last thread I started on wastegates and actuators, I'd guess if the leverage is similar, hence similar power is needed to operate the wastegate, shouldn't be a problem...

Hey Freddan, sounds interesting...

so if you have to cut the DP and weld a new flange onto it (which diameter and flange type btw), what is the benefit of it as opposed to the Garretts ???

apart from that, what do you pay for a 19T - are they cheaper than the GTs ??

Greetz Jochen

looks like a nice turbo, good operating range from the look of the flow map and a slightly higher efficiency than the garret. looks like a good choice to me so far, i hope you dont have too much of a problem fitting it.

Hi Jochen,
The turbine outlet is 2.5". I will use this flange see pic here . The downpipe is 2.75". Hopefully the exhaust gases can escape pretty fast
Compared with the GT28RS it should spool up better and hold boost better at the top. But I will only know for sure after I have visited the RR

My turbo was a cheaper alternative than a GT28RS.



Thank you! Let´s hope for the best.

just been comparing the 19T compressor map with the map for my GT2871

observations:

The surge line is broadly equal
the efficiency island of the 19t is lower, but about the same legth (19T runs from 0.4 bar to 1.4 bar - 2871 runs from 0.6 bar to 1.6 bar)
19T looks to be more efficient - it will *almost* move 40lb/min at about 1.4 bar at max efficiency - 2871 is off its efficiency island to move 40lb
dead centre of the efficiency island for the 19T is 30lb @ 1 bar - 2871 is about 28lb @ 1.2 bar

My only worry is that the 19T appear to be a smaller turbo - the turbine revs are much higher at any given boost pressure (eg 1.1 bar - 19T is running at 130,000rpm, 2871 is running at 103,000rpm)

My guess is that this turbo will give very good torque figures and will spool up nicely, but I wonder if its better suited to a bigger engine that will shift more air

I'll be very interested to hear the results

Freddan - are you 100% sure the exhaust will fit on the end? I replaced my turbo the other week and it was pretty tight in there.

100% procent sure

On the T5, I dont think anyone runs higher than 1.4bar with the 19T, in the UK at least. Not sure what the swedes do. 99% of those that upgrade to the 19T have come from either a 15G or a 16T turbo, their usual comment is that the 19T feels laggy.

Ive been driven around in 2 T5s with a 19T and a GT2871R and id choose the Garrett over the 19T any day. Whether it was the difference between the 19T havinga 2.5ltr engine compared to the GT that had a 2.3 I dont know, or the mapping, but the GT28 felt more powerfull and was a league above the 19T.

Small update

The car is in the garage now. Jippi!!
Can anyone see a turbo??

The old turbo was not in top condition . Now I know why it was smoking.
Turbine housing

Here is a pic of my SIP:
Wooooosch, says the air when it passes the air flow meter

I will also change oil and oil filter. I will use Agip Racing 10w-60. Best oil in the world

Bet you cant wait freddan

The fun of changing a turbo

Ben

Here are some more pics from the installation

19T in place

Wastegate actuator

SIP and dumpvalve back in right position

Finally - downpipe with new flange

Tomorrow we will start the engine

Good work

Looks like a very stock installation, and hopfully it looks
like the heatseild will fit without haking it

Ben

Today we started the engine. No oil or water leakage so everything is perfect . No blue smoke either

I will drive the car tomorrow and start to see how the turbo charges. I have made one change from my to do list. I´m not using the wastegate from the TB2810 turbo. We wanted to test the wastegate that came with the turbo. It´s a little bit stronger and opens at 1 bar (TB2810 opens at 0.6 bar). I let you know how it behave

The heat shield fits perfect. From the outside you can´t see that the engine has a new turbo. Just the way I want it

Okay so finally everything is working

We (I and my mechanic) had some problems with the boost pressure. So we took of the pipe for the wastegate actuator and stiffen the wastegate rod and went out on the road. The turbo boosted like crazy . At least now we knew it worked. So back in the garage and hook up the EBV and out again on the road. Now the pressure went up to 1.5 Bar and something else happened. The clutch slipped Damn! So now I need to install a better clutch if I want to use high pressure. After the second run my mechanic loosen the wastegate rod a little bit and we tested it once again. This time it hit 1.3 Bar and no slip

Next tuning step will be an adjustable FPR and RR session. Can´t wait....

Sounds good. How is spool up and how low in the rev range do you get boost?

I haven´t checked so much. I have 1 bar at 3000 rpm (4th gear), 1.3 bar at 3500 rpm (+/- 200 rpm). I will check it more properly after the RR.
This week I will install a FPR and head to the RR next week. I post result a.s.a.p.

New Malpassi 1:1.2 installed. At first I was thinking about a 1:1.4 but changed my mind and went for the smaller one. I will fine tune it at RR next week.

Is it vacation here or what??

Well yesterday I was at the RR place and everything is working okay now. I will soon post results in the RR section
