First off let me say Hi, I came across this thread while surfing the web for who is doing what to the Regal thus far, sadly to say not to many besides tuning readily available.
I also use to own a HHR SS with a BNR 2871GT turbo upgrade and making 390whp on E30 blend and 375 whp on 93 Octane. Tuned by Vince at Trifecta.
The dynograph above is Vince @ Trifecta's, he is the owner of Trifecta performance and personally owns a 2011 Regal CXL T.
Everything he has told me is the engine is de-tuned and on top of that I've been looking over the factory Buick stuff, it is small stuff all around.
I will be getting this tune in the coming weeks, but first I'm upgrading my UICP and LICP using LNF parts. You would also need a LNF turbo compressor housing bolt on tip as the stock buick regal plastic UICP bolts straight to the housing.
The factory stuff is about half the size of the factory LNF stock stuff.
For the UICP I'm going to use the LNF stock rubber pieces along with a Dejon UICP piece.
For the LICP I'm using a LNF LICP.
I'm also upgrading the stock Buick IC which measures in at a tiny 26 x 14.25 x 1.25 which is roughly 463 cu in.
The intercooler I'm looking at is of the same build but measures in at 25 x 12 x 3 for 900 cu in.
I've also looked at LHU engine pics online and to my surprise the LHU down pipe is using a LNF flange for the DP to turbo, good news is I have my old LNF catless SS DP sitting here, bad news is I'm going to have to have the DP custom made. But I have the flanges and will have the stocker with me so they can bend the shape I need.
Later on I will be upgrading the stock Buick Regal turbo to my BNR 2871GT unit and running a BOV with MAF relocate like I did on my HHR SS.
Who needs a 270 hp FWD GS when you can have a 300-350 whp 2011 Buick Regal AWD T
