What turbo upgrades have you done?

[Kalle]

Please write here if you have done a turbo upgrade!

State the full name of the new turbos and what modifications that had to be done! A quick review on how the upgrade affected the performance is also appreciated!

Off topic, sorry, but you know you asked me to change your name.......you have forgotten to change your car info

[Kalle]

Has no-one changed their turbos??

[BraindG]

There a few that have done some light work to the turbos.. zentac is currently converting to a single turbo.. but no large scale work has ever been done...

The best you will get at the moment, I think, but Zentacs single conversion is becoming interesting reading!

That's an old link...
I've changed my turbos to pair of TD04L-13T. I won't be running more than 0,5-0,6 bar of boost until I have all of the "suporting" mods in there.

... I won't be running more than 0,5-0,6 bar of boost until I have all of the "suporting" mods in there.

Even by accident?

Even by accident?

Yeah... sh*t happens ... but no, boost didn't do any harm to my last engine.

It was a spun bearing, caused by oil contamination... due to a "human factor" actually. Guys that were putting my engine back after an accident didn't feel like checking the oil pan for debris left over from a damaged head cover...

I'd have thought you could get any of the TD04 range of turbos on to the car, so 9b's 13G's, 15G's right up to 19T's.

The issue would be physical space i'd have thought and having enough fuel to support them.

Cheers,

Ben.

So aren't all TD04's external dimensions the same??

[bradc]

Ben, while you probably can, to fit a TD04 onto our cars you would need to get manifolds, downpipes and a ton of oil and water lines made up, the stock ones just won't work.

You can use stock manifolds.
Downpipes... well, what you really need are those parts coming of the turbo exhaust sides and down to downpipes.
Oil and coolant lines to turbos - stock lines will work with some modifications.

So in a prefect world of course you would need custom made manifolds, new downpipes and 4 oil lines plus 4 water lines, but...

PS: I advice you get an oil filter relocation/movement kit.

Off topic ... just had a run with Kawasaki ZXR750

We stopped at the light, my car and two bikes (second one had a FZR something sign on it), two people were sitting on a 750. I asked him "How fast is your bike from a stop?" His reply was - "Wanna chek it out?"... Sure! Well they lost the start and didn't catch up until I eased off at the next light ...

Bike driver was kinda disappointed... all three of them actually...

- "What've you got in there?"
- "2,5 Twin Turbo"
- "If I was alone - would take you out..."

Well, I guess they were kinda late - cause they took off and didn't hear me reply "Next time you are going to ride this thing alone I won't be running only 0,6 bar of boost" .

Hell, I love this car!

PS: We just had adjusted fueling with the help of LM-1 and Ultimate... 0,6 bar does feel good now!!!

What's you 0-60 and 0-100 Valmes? Any 1/4's recorded with your latest setup?

[valmes]

Apexi RSM today recorded 5.30 sec 0-100 kph (~4,96 sec 0-60mph) and 13,74 sec 400 meters (13,81 1/4 miles). I didn't push the car, just wanted to know how well it goes without making too much effort on the drivers side... so I probably did a lot better with bikes since it felt more important at the moment! Yesterday, I was with my friend in the car (both me and my friend are 105 kg ) and slightly up the hill - RSM recorded 14,08.

I know those are not the results to be proud of, but were done with boost holding around 0,6 bar to redline.

[Nick Mann]

They are very good times for 0.6 bar! Surely if you are running 0.6 bar then the only advantage over smaller turbos is the efficiency? Has the fuelling changed much with the turbos? Have you/when will you set it all up for higher boost?

[Wodjno]

Sounds impressiive Valmes

0.6bar and sub 6 sec 0-60's Is that about 8psi ? So not far off standard boost clocking more than 1 sec quicker to 60mph.
0.6 bar held to the red line isn't that impressive Well not for 2 x TD04's .. I reckon they would hold 1.6Bar to the Redline Whether your engine would aswell isn't a different story

Maybe i shall carry on and put on my TD04HL's..

No, I think you misunderstood me

I am running wastegate actuator pressure... or stock boost! So holding 6 bars to red line is not a limitation of turbos (well, I will tell you more on the subject when the time comes... there is a bigger misunderstanding in all of this - don't blame me... later. I will explain it later... ). They can hold 1,6-1,7 bar to redline, but I haven't got my hands on Apexi AVC-R yet (I bought it and now waiting for it to be delivered). Already got Grex oil cooler/movement kit, Exedy EVO 7/8 metalaceramic Twin Plate clutch kit (pressure plate and flywheel included), waiting for my third (duh... I managed to brake two intercoolers so far) intercooler and a Hybrid datalogger cable from US, as well as LC-1 WB cable... right now I am using friends LM-1 to tune. BTW, Just replaced my broken Blitz Blow off with HKS SSQV - its loud, but I like it!

Hopefully I am getting last bits over the next week and will start putting everything together...
Yes of course I have altered the fueling… that would be a crime, not to.. when you have LM-1 attached to e-manage Ultimate sitting in a Turbo car

[Kieran]

I can't get my head around turbos at the moment. Or, more specifically, how you "size" a turbo to an engine. But I did spot these. So, would someone be gentle with me and tell me if these are any good?!

Kieran ! I think thats pretty much like what we have on our cars now

But i could be wrong !!
