Default So after a year of research finally getting my turbo in!

Ok, so I've had my Begi-S kit sitting around for about 8 months and just now getting to it. It took me a while to get all the parts I needed and doing searches like a madman to figure out the best way to do things.

So I got the Begi-S with a mild steel separated-gas downpipe. Upgraded to a Garrett 2560 turbo. I'm running Megasquirt and an ebay intercooler so I didn't order the fuel riser or crossover pipe so saved some money there.

I installed my M-Tuned dual feed fuel rail along with the RX7 Hi-imp 550cc injectors-this went very smoothly once I found the right fittings at the parts stores, the rail is a nice piece and install was a snap. I ended up just using 90 barbed fittings with fuel injection hose clamps and T-ing off the existing fuel feed line. No leaks! I used the yellow Teflon tape on the fittings that is supposedly fuel-resistant so we’ll see.

So, I upgraded MegaSquirt to the Hi-Res code and adjusted for the new injectors and wired up my GM AIT sensor and it fired up just fine! I do have an issue with the reading on my AEM Uego wideband not being the same as what is displayed in MegaTune and I know there is a number you can adjust in the Lamda Sensor file I think it is so I'll need to get that sorted out but my datalogs show the same reading as what is on the AEM gauge so I'm assuming everything is ok-I just can't go by what the MT gauge says. Hopefully I can get that fixed.

The Begi kit fit fine for me, getting the stock downpipe clamp off was a bitch though-broke one transmission bolt that was seized, ended up having to hacksaw the rusty bolt holding the clamp on and beating it off the rest of the way with a long piece of metal stock and a 5 lb mini sledge hammer. All I can say is to PB Blaster all of the bolts ahead of time-I did, but I missed a few. Anyway, once I got all the stock junk off I just followed the Begi instructions and it was pretty easy. No fitment issues that I know of! Hopefully the engine won’t move around too much since I installed Mazdaspeed Comp mounts (well I did the one on the hot side and left the stock one on the cold side because it looked like a bear to get up in there-already removed the intake manifold brace for better access to the oil filter). Will probably rebuild the engine next winter (or as long as the stock engine lasts on turbo-I have 160k miles!) so figured I would just swap out the other mount then.

I still have some work left to do-need another 45 degree silicone coupler (on order) to complete the intercooler piping and then hook up the BOV and recirculating system. Still need to make a new undertray and also put some sheet metal inside the front end to direct airflow through the radiator. Also plan to build a heatshield to separate the brake booster area and intake filter from the turbo area. Will post more pics when all of that is done! While I’m waiting for that, I’ll be setting up the .msq I want to start out and then street tune it. Looking forward to getting this thing on the road!

oh, the wires running across the engine bay are for my fans-I have them temporarily hooked up to run when the car is on but still need to sort out where to hook them up permanently so Megasquirt controls them.
