Well, it's been 4 and a half years since I rebuilt the engine and ever since, it has taken the abuse I've given it like a champ. High EGTs and 87 octane fuel was the order of the day. It took it like a man. Compression was perfect across the board, and everything else was good to go. Well, you know how they say that you shouldn't have sexy time in your car because it jinxes it? Well, I think that actually is true, because before breaking a piston the first time, my car was the place of some love encounters with my girlfriend, LOL. It can't be coincidence that it broke again after I disrespected it with my current girlfriend. Blown tires and some other things happened before, too.
Anyway, the last straw that broke the camel's back was a 15 PSI test run after tuning it with the eManage. We were gonna take it to the dyno to tune it at that boost level, so we needed to test if the engine would hold or if it would blow like a grenade. Too bad I forgot I had moose piss 91 octane watered fuel from a gas station I never go to, but I had to this time because I was running low. I thought I had Shell 93 and well, nothing made a sound. I nailed it from a dead stop, it just roasted tires with the 17s, put our heads against the headrest, and then coolant was all over the windshield when I let go the gas. Good times. The auto tranny is holding well. No signs of slippage or anything. I ordered a Cometic headgasket and should be here this week. This engine can sure take some punishment. I need to up the boost to see if a rod gives up before a piston. I need an excuse to install the Belfab rods and some other pistons I found. -------------------- |

Well, I started working on the car yesterday at 11PM and finished at 3PM just cleaning things up and what not. I was up for 27 hours. Only ate McDonald's for breakfast. I slap on the new turbo and now the car is smoking like crazy...just like with the old, broken turbo. The turbo is laggy but not as much as I expected. It's quiet, though. The car vomited a lot of oil out of the PCV one time, and that was it. I checked and the engine is not broken, so it must be the turbo needing a rebuild. If it's not the turbo, I'm sorry to say it but I'm done with the 7A-FTE. I proved that it would hold over 200 WHP and the auto tranny would hold. I did never test the limits of the engine, but whatever. I'm focused on making real power now. My buddy hooked me up with...um...a swap. Yeah, I said I would never swap, but the pressure is ridiculous. Everybody around here is fast now. If you run 11s, you're slow. I have my ZX-10R for the speed cravings, but I miss good power in a car. The 7A-FE proved to be reliable when turbocharged. I'm ready to move on to something bigger. I'll probably take it to the dyno again but I'm done with this engine. I'm ready for something better and that spending money on it is worth it. This is an economy engine. What I can get out of a 3S-GTE with a big turbo and stock internals, I have to swap forged internals, get a beefy tranny with the 7A-FTE, AND still be stuck at that power limit while the 3S-GTE is just starting to make power.
