This is a $1000 junkyard motor with forged internals that, unmodified, makes 160+ hp out of the box. With bolt on OEM turbo or super options you can go straight to 300 whp territory. The VVT on both intake and exhaust cams allow awesome torque at low RPM, which you won't see in your mild BP build.
Mainly though, I like tinkering and swapping and fabricating. Throwing money at a BP motor is much less fun than figuring out new ways to put square pegs in round holes.

A guy in SoCal built me a harness from 8-foot MS3Pro flying leads. He turned it around in a couple days and it's pretty tidy. He does a lot of ecotec and other GM harnesses. I'm running (by running I mean, plan on running, when it is running) full standalone with a MS3Pro EVO. I did that for turbo power, but it's an option either way. It didn't come out cheap though, it was in the $7xx range IIRC, plus the ECU and leads from DIY.

I'm currently working on removing any wires not needed for the ecotec to run while retaining all of my cluster / combination switch functions. Kind of in the middle of street car and racecar grey area that never ends well.

The setup from Swap Specialties did not include a tachometer out from the ECU. A bit of web searching seemed to indicate that it was as simple as adding a few wires...
On the GM E67 ECM, you can get a tach signal from pin 25 on the J1 (blue) connector. pin 24 is a pull up resistor to make it useful for most tach-driven devices. I ordered some pins (Molex MX64 33467 Series Female Unsealed Terminal 0334670005, Cable Range 20 18 ga (0.50 0.80 mm2)) and added them to the J1 connector, then connected the wires together and to the Traqmate tach input, and it works perfectly. I checked the tune to make sure "crank" type RPM output is enabled - it won't work if the tune is set to serial or frequency engine speed output.

I had issues with gaskets exploding and bolts loosening at the exhaust flange during the shakedown

So I replaced the flange with a vband

A bunch of oil plumbing. I put a bypass adapter in the block, and routed the oil to two parallel oil coolers, then through a remote filter, teed to an accusump. This was $600 in AN fittings alone.

The car ran great! It's right at home in ST5 - On Maxxis I run 2400 lbs at 162 whp, and on Hoosiers run 2465lbs or so. The Ecotec is pretty good on track. The low end torque really helps pull away from corners.
