Well, since you're done ****ing around with this, make me my damn rear sway bar!

Awesome turbo for sure, however it's a $1600 turbo, and the EFR stuff has a much larger "foot print", and it may not fit in the space available.
The EFR turbos have a ported shroud compressor cover. That's why they don't surge. No such cover for the small T2 framed Garret turbos.
I'll look into it. Thank you for the suggestion.
Ha! I need to get back on that for sure, and I doubt it would be so damn irritating!Well, since you're done ****ing around with this, make me my damn rear sway bar!
I agree. In order to feel good about using this turbo I would need to upgrade all of them to the larger thrust collars and better thrust bearing. There's also cutting, welding, and porting of the waste gate that also has to be done. Then there's the surge....Paying an additional $800 to have a turbo which doesn't need rebuilt every few hundred miles seems like an easy decision. The fact the Borg will have more headroom and likely spool faster is just icing on the cake.

On paper, this turbo matched up beautifully, but the reality is it isn't. The problem with the EFRs for this application is two fold. First off, my goal was a sub $2,500 dollar turbo kit for the masses. If $1600 is just for turbo, I don't know how I can accomplish that. Secondly, they are enormous. I don't know if I could even get one in there.
If I had one to test fit with, and it actually fit, I'd be much more inclined to learn towards using that turbo for all benefits it has over the current choice.

These diagrams say otherwise. The EFR is almost 4" longer(98.9mm) and the comp cover is much larger in diameter.While I haven't seen a 6258 next to a 2056 I don't think it's too terribly much bigger. It's wider more than anything iirc... If you need more width just relocate the coolant reservoir over a bit and use some of that space. I know all of this is easier said than done but I've seen bigger turbos in smaller engine bays, just have to find the right position!opcorn:

Time would be far better spent on buying a z20ler from the U.K. and bolting that into the car.It's going to be an electrical nightmare...just saying. The 2L DI motors use a different ECM which likely (just speculation, but I've seen this go sideways on many other GM platforms) means the cluster, ABS, BCM, etc will not function correctly when paired. BUT, I'd GLADLY eat my own words and drop a 2L DI motor into my Sonic.
Might have to set it up where the E39/E39A ECMs run the engine (and a T76 for auto, same TCM we use but in a vastly different trans and therefore the OS/Calibration is different) then send the RPM/VSS/etc signals to the E78 to run the cluster/creature comforts. That's the route I'd take immediately, then sort out if the E39/E39A can run our cluster/creature comforts at a later date once it's running properly.
Happy to help with tuning knowledge/swap, just let me know.
