Must be senility setting in. I have this solid but apparently incorrect memory of Honda putting ultracapcitors in the Insight, and that was part of keeping it light.

Stupid brain

Friends and family threw me a surprise graduation party today. I was genuinely surprised too! Had quite a good time!

Yea that's what I thought, no one has used ultracapacitors yet, Li FePO has only recently become standard, and they're talking about ultracapacitors only recently.

I'm starting to wonder what can be done to the stock 1ZZ motor in the MR-S...afterall, it's got the same displacement as the 2ZZ, and the rod stroke ratio is a healthy ~1.6. I'd imagine that no one gives a crap about that motor though, so upgraded parts would be hard to get :/ Maybe force feeding it to ~200Nm should do the trick?

I believe TRD made a SC for it. But my memory's not having a good run today...

I think they did, but I wonder if a SC is DIYable...buying the compressor and shit is pretty cheap, and maybe I'm wrong but I think machining chunks of aluminum to make brackets and stuff isn't too hard?

At any rate, that 6900rpm rev limit on the 1ZZ is unacceptable and needs to go up :P I imagine new rods would really hurt the wallet though :/

Say, how hard is it to rebuild an engine anyways? I saw someone doing it in a Youtube video sped up, in their garage...

Little to none, going to AUTOx this weekend, HPDE after that, then time attack. I'm just trying to find out what kind of spring rates and sways my car will feel neutral on. Right now I'm fighting understeer... and the only solution I know of is a bigger rear swaybar. Front is 26mm, Rear is 17m... my weight distribution is roughly 60/40.

Do you think, having a massive sore is a good excuse not go to work?

prob not LMAO

Leave it more or less stock for the time being, but upgrade the brake pads, lines and fluids before you go to the track. If you feel a burning desire to throw money at your suspension right now, get an adjustable rear sway bar.

The important thing is going to be getting enough experience to be able to reliably troubleshoot your setup. First and foremost you need to know where you're understeering; Corner entrance, a quarter of the way in, mid corner, a quarter of the way out or corner exit, and on what types of corner; hairpins, sweepers, decreasing radius, increasing radius, etc. All of which are going to have different solutions which will need to be considered in conjunction with the way the car is behaving on the rest of the track; Is it stable under braking? Through that high speed chicane? etc. Everything effects everything else and no one setup will be perfect on every part of a track, much less every part of every track.

Anyway, step one is go out there and drive the damned thing.

Typical response for some asking help with suspension tuning. It understeers EVERYWHERE. A 20mm swaybar should have been a factory accessory. You must understand, I know how the car feels and that's why I am concerned about tracking it. The only burning desire I have is not wasting money on a 20mm when I really need a 24mm. Like I said before, I am looking for a neutral setup, not a perfect setup.

I know that driving the car around a track isn't magically going to help me understand what spring rates my car needs either. I dont know why anyone without track experience asking for help with suspension always gets shot down. Do you have any track experience with a FWD double wishbone?

btw; brakes are being done this weekend. I'm well aware of their limitations.

Hm... some local guy is selling RWD GF8... VERY tempting

So much hype this past weekend leaving so much disappointment to all.

It's not, if you know what you're doing. The difficulty from a DIY perspective is access to a mill and/or lathe plus all the tooling. If you have a LOT of time, patience and attention to detail, you can substitute a drill press, bandsaw and files for a mill. But after one time, you'll never want to do it again...

This has been a source of endless frustration for me over the past 3 years.

Trolling through Netflix last night looking for a comedian to watch. Ran across Sinbad's Afros and Bellbottoms" special from HBO circa 1993. My 15 year old was literally ROFL from it.
Some of it was a bit dated (references to Rodney King) but I had forgotten how funny Sinbad could be. Reminded me of a more "hip" Bill Cosby, hillarious and relatively family friendly.

Very bad VHS-DVD transfer (even the credits had the VHS stutter thing going) but worth a revisit. Be patient through the opening vignette though, it was pretty lame. Once the actual standup part starts its much better.
