I continued that back stateside and until recently always raced 13B RX7's, 4G63 DSM's, and of course, those odd 73 and 74 German Capri's with the 2.0 Pinto engine. In fact because I did so well building powerful 4G63's, a Mustang guy I raced regularly against ended up trading that for a Evo X (and then a year later I ironically got a LS3 Camaro and started modifying that). So I'm no stranger to Japanese imports.
All those engines STILL revved better than this stock FA20...until maybe recently:
Going on the assumption that Toyota employs some timing retard function or low octane table from knock sensor input and assuming the dealer's "free tank of gas" was 87 and not 93, I disconnected the battery early yesterday morning until lunchtime when the wife wanted to take the FRS for a spin. The motor definitely feels a whole lot more responsive, but I'll reserve judgement for a couple hundred miles. Also, it seems like the oil is a 1/2 quart or more high, so until I pull that out, I'm a bit reluctant to rev this much past 6k.
I did order a Perrin crank pulley, but I'm still not so sure how I'm going to sell the wife on the idea of a lightweight flywheel/clutch assembly. I might be able to slip one in when I put a full exhaust on, then just claim preventative maintenance "since the car was in the air"  |
Okay, so it is okay to run crank pulleys by themselves, so that wasn't clear in my original post, however there will inevitably be additional vibration transmitted to the crank, how much you would have to ask Perrin. It is ALWAYS in your best interest to balance the crank from vibrations as it could lead to main bearing wear, I suggested the flywheel, however that may or may not correct the issue, as the weight may still be off (does that make sense?). Anyways, wait until you have atleast 1k on the engine as my engine feels completely different know, than it did when I bought it.
