              Not pictured, breaking two piston rings and even breaking the shitty wrinkle band ring compressor, buying a tapered ring compressor, getting the wrong main bearings, getting the wrong clutch and pressure plate, lugging the head, block, and crankshaft to different shops in the back of my G35 Coupe, and getting my hands greasy af for like 10 weekends straight.

                          I will be running Motronic 1.3 with the 173 ECU and an Sssquid tune. The tune is stage 2, 91 octane, M50 green top injectors.

                          I'm shooting for about 200 bhp to start, but plan on changing things incrementally later. After I'm sure the setup is solid, the car has passed smog, and my wallet feels heavier than usual will I start changing externals.

                          Long tube headers and ITBs are on the want list. Hoping for 200whp all said and done.

                            Thank you!

                            Feel free! It's been a learning experience for sure.

                              I'm betting it'll make more than 200whp if the tune is optimized for your specs. It'll be interesting to see where it ends up.

                                I really think so too. No need to get caught up in numbers at this point, though. So long as it sounds bitchin, and embarrasses my roommate's 2017 BRZ ;D
