Alright today sucks, from the top.
So I go out to the shop today because today is startup day for the GSX. Finished up some minor things, fluids, connections, DEAD battery, Well we plug in the laptop to the megasquirt, calibrate wideband & after a few tries, she fires up & runs decent runs for about 10 min. then I change the oil. make minor changes to ignition & tighten lug nuts & take her out for a spin. We ease the car for about 10 min or so, slightly boostin a little to hear the new FP3052 spooling, WOW ball bearing is alot different than a standard wet bearing turbo. anywho... sounds great. Since the car has not ran in 3 months I had drained the fuel. SO I FILL it up with 93, which is $2.85 a gallon. when leaving I gas the car to see what I am boosting as, the tial wastegate has a 15psi spring. So I boost 13psi, the open dump wastegate opens & DAMN its loud. well I am loving the car, so we decide to install the boost controller. Well after installing it I turn the boost to 19psi. DAMN it pulls really hard, the the laptop dies. We have no idea what the duty cycle is or AFR. So we head home to charge the laptop, well on the way 2 miles away, I get on it for a long pull from 3 to 4th, middle of 4th WOT its pulling really hard, then I only have half that power, I let off & smoke is everywhere. & it's missing badly. so I limp it home I pull in the the shop raise the hood & it looks like a 3 ft N20 purge coming out of me valve cover breather with 2 qts of oil all over the left side of the engine. serious blowby. the results are 3 broken pistons. The cause: the 450cc injectors were in, not the 720cc, & I know I was a 85percent duty cycle @ 13psi, so yeah 19 psi I def. ran out of fuel.
NOTE TO ALL, Take your time & monitor EVERYTHING, laptop dies, CHARGE IT, don't boost untill you know your not maxing out injectors
& have the correct AFR
So now I am in serious need of pistons & rods jE pistons & Eagle rods is what I need,std. or .020 over 7.8.1CR to 9.0.1CR for a 1990 6bolt If anyone knows anyone I am willing to buy trade, whatever it takes, I need to have the car running in a week & a half.
