Why are there not full frame or at least hybrid turbo options and more robust custom tuning options for the 2.0T Giulia after a good 2 years? I'm finding it rather annoying that nothing has came to the market with these with such an easy turbo location for replacements and easy ecu to deal with similar to continental simos ecus. Even the downpipe options are sparse and it's only 2 bends with a funky turbine flange. This engine is after all fully forged; crank, rods, pistons with oil squirters which could easily support 500whp/450wtq with proper calibration/fueling.
Lack of bigger turbos and tuning. Discuss.

Ive been talking to one of my friends in the volvo community. He manufactures hybrid turbo's for the S60 and S60R platform and wants to get in to ours as well. I'll be sending him a core this week for him to disassemble and work his magic. The idea here is once we have a proof of concept and I can run it on a local dyno for real numbers he will offer the conversion service to the community for those interested.
I would be interested for sure.
Yeah 400whp is a farfetch for our turbo..I’m good with 360-380hp
Yeah, the first step is to get him the core for inspection. He has to measure both housings and see what he can machine to fit inside of it. The goal is to produce a product that looks identical to the oem turbo so if a dealer looked at the car there would be no easy way to tell that it was modified. Our goal is to find a combination that will get 400whp out of it but might not be possible. I'm confident he can work is magic to at least squeeze as much power out of the oem unit as possible.
I would like to state that users would likely need a high flow or cat-less down pipe to get the full potential.
I all measure... there is No option to put sth bigger.

Silly question, I can see the borg hot side if I zoom in.
Are you running a adapter plate for the exhaust manifold?
Adapter is done engine is fine, we are waiting for tune.

He's done a lot of nice work in the Volvo community, i'm sure we can at least come up with something to squeeze more power out of it. My friend says that the core is popular among other brands and it shouldn't be to difficult to modify but that he would need to seen it in person before making any promises's.
Going aftermarket like Kozak is always an option but I'm looking for something to keep my warranty intact but pump out as much power as possible.
Awesome, I'm interested to see how it will hold up. The 2.0L K20 blocks from honda can make 450whp all day long and some people have even squeezed 600hp out of stock blocks. I'm sure RPM might be a limiting factor with our 2.0L multiair but it will still be interesting to see what kinda power it will make.
I wondered how you were getting electronic wastegate to work or figured out how to bypass it. Interesting.
All is done, and working [emoji846] wastagte is from stock turbo

What about low end torque and turbo spool up? More power is great but if it is not usable except in a long straight line, it is pretty much not usable to me at all.
Also some effort to get a California executive order would be great, preferably for a high flow cat + hybrid turbo + 91 octane (R+M/2) tune combination. I certainly would pay a premium for a smog legal setup.

Spool up would still be fast. We aren't changing a lot here, there's only so much space we have to work with in the stock turbo shell. Sure we can do a bit of machining and swapping wheels but this isn't a radically big change. It helps these units are already a divided style setup for quick spooling times.
In theory the tubo will look the same as OEM so Cali tech can stare at it all day long and never be able to tell its been modified internally.

What is done? You cannot gain a lot of power at sea level unless you have a tune that will allow more boost.
You can gain a lot of power at high elevation without a tune, largely because the turbo cannot keep up at high elevations. I can only get 14PSI (about 1atm) boost at 3000 meters elevation at the redline, meaning I barely get 200chp.
If you tune for more boost there is risk that expensive components like the high-tech plastic intake tube will fail from the increased heat and pressure.

The OEM turbo can produce about 10PSI boost at freeway speed in 8th (1800RPM engine speed) at least at sea level. That makes the car nice on long/relaxed drives as it minimizes shifting and maximizes fuel economy. Would a hybrid turbo still manage similar performance?

But then you have not told us anything either.
I'd need to put it on a dyno to see how it spools at cruise. I'm not the turbo expert however with the hybrid but it should be similar +/- >2lbs
On the topic of fuel economy, under A mode isnt the car limited to 5lbs of boost?
