        Finally came back to town. Had a solid 2 days to work. Bolted everything back on. Oil cooler on, intercooler on, fuel, electric, fresh gas and cranked it. Nothing. Took a solid 30 minutes to figure out why it wasn't turning on. Many thanks to Otis for spending the time out of his weekend to troubleshoot with me. Tested for spark, tested injectors with test light, double checked everything. Turns out fuel out is at the FPR. Switch fuel lines and fired her up. Didn't have much tim ego hang out, ran straight to miami for the FSU-UM game. I'll be down in a week to finish everything up. Here's some pics.

            so mechanically car seems to be 99% done. I did a lot of cutting of the front valence to be able to fit the intercooler. All that needs to be done is headlights and bumper.

            Alignment is done , new steering wheel is on and every nut and bolt is double checked.

            Problem right now is engine and the hesitating. The engine fires right up and idles well, maybe a little low because it will easily die. When I drive it seems as if it has no power and hesitates, i also heard a misfire.

            Im attaching pictures of the bay and of my fuse box. it seems there are 2 fuses missing when I compare it to how the other ones look. The car ran fine before the way it was.

            Also my O2 sensor was not in when I got the car...just dangling from the chassis. I wonder if all the dirt and oil it picked up over time is making it not read right now. ...also confused why engine ran fine without it before?

            I attached another picture of a connector I have no idea where ego connect.













            hard to see but theres a black connector there just hanging out of the wheel well.

                    Could be a few things.
                    What are the AFR's at idle and when it bogs ?
                    Could be a vacuum leak. Best way to diagnose is with a OBD1 code reader to see what fault codes it getting.

                            A lot of progress. I will post more pics over next couple days. Gauges done and working.
                            Interior getting cleaned up, reassembled and front valence and bumper finally on.

                            Looks like at idle my AFR is around 13. and quickly leans out past 16 and boggles and stalls.

                            Doing troubleshooting now.

                            First redoing the vacuum lines as I set them up incorrectly so my boost gauge is barely getting a reading. Right now I'm running boost gauge BOV and wategate off one tap and quickly learned thats no good. Will tap manifold to have semerate vacuum line for waste gate. Then will run a tap for BOV and boost gauge.

                            Have to wait till monday to get access to an obdi scanner.

                            If anyone has any ideas why I'm idling so lean please shoot.

                            also finally wrapped DP.

                              Why not have the BPV near the turbo before the intercooler so you don't need that long recirculating hose.

                                Lol I should/will probably switch that up. I figured it would save room on the passenger side of the car but there is plenty
