  1. Hey H, while i am enjoying the fiat-ness of your posts as much as the next guy, do you think it might be time to rename the thread?
  2. Are you kidding? Sign me up please; been waiting for one of these for months..

    Love that exterior color; wish there were more of them on the west coast. Just splash some agua on Jorge; that should wake him up.. cue the dead parrot skit..
  4. LOL!! I told you; I wasn't kidding! The kawa frames, brakes, and suspension of that vintage were scary enough w/o too much HP to boot. Seriously, be careful!
  5. Before you move all your stuff in, we're gonna need a vid of you doing some donuts in that space, and don't tell us there's not room..
  6. Now that's a fun DD!! Is that 3.5" all the way back?
  7. Good job! So what was the no-start problem? Aren't dealers hilarious?!
  8. Very interested in specs, features, and price. That's very cool; will fit nicely in glove box or where ever..
  9. Good job! Best way to finish any TODO list!!
  10. Do you have any links showing this product? Sounds interesting..
  11. Yeah I looked for compatible stalks/parts on bmw/vw/audi/etc but didn't find anything; not saying it's not a possibility, just not one I ran across in my limited search.. Most other systems that I looked at use much lower resistance value pots than this circuit; makes sense as this would give you better noise immunity (though I haven't run into any issues so far). Inside the wiper relay assembly is an atmel U2640B chip which is the logic chip. It's a dedicated automotive wiper control. There's a comparable chip Temic U846B that i discovered out there that is more configurable than the U2640, but the only source for it I could find was alibaba so who knows what the quality is like.. it had different pinouts too. If you're going to go to that much bother you may as well create your own PLD..
  12. Most of you guys probably won't care about this, and it's not really a perf mod so this could be moved if this isn't the right spot for it... But one thing that's really missing on the 850 and '98 S/V70 cars IMO is a variable intermittent wiper control! Yeah I know, you can get a wiper relay from ipd and others where you can change the intermittent interval time but the UI is terrible; it's a PITA to change the intermittent time interval; you gotta get all jiggy with wiper switch to modify the time. Link for ipd relay http://www.ipdusa.com/products/5324/103226-adjustable-delay-intermittent-wiper-relay The last car i owned with a variable intermittent wiper control was a 2001 MY saturn L200; it just had a knob at the end of the wiper stalk that you twisted to get different time intervals. Very nice and easy to change interval times. I don't know about you guys but where i drive the rain/mist rate does not stay constant during my drive; and of course it changes with your speed too. So (barring rain sensors automatically controlling your wipers..) the knob is a very nice UI. So I dug into our wiper relays and did some reverse engineering. There's a RC network that controls the time interval and it's locked down to a 6 second interval. Actually I did more experimentation than engineering; I can get into more details if anyone is interested but suffice it to say I did figure out a nice mod to add variable intermittent wipers to our cars. Caveats: This mod will only allow you to vary the time interval between 4 and 16 to 17 seconds. I wanted to make it longer than that but that would require more extensive mods to the wiper relay. The mod is not plug and play. This was disappointing to discover. i calculated the max resistance necessary to be around 700K ohms IIRC from the U2640B data sheet (link inside below link) but on my 855 it actually came out to 370K. And on my wife's S70 it came out about 520K. I.e. you will have to tune each installation a bit. Couple more items I forgot about... when in delay mode above about 10s or so the wipers will park a bit higher than normal. Not a big deal; if you go from intermittent delay mode to off, just do a single wipe and they'll return to the normal park position. If in the max delay intermittent mode and you pull the stalk toward you to wash the windshield, the time that the wipers run after the wash will be extended. If this becomes an issue for you just turn the pot to the shorter time position and will return to normal operation. Here's a link to some pics illustrating the mod. I did it to both our cars now and it's one mod the Mrs definitely approves of! Basically there's a 200K resistor in your wiper relay. Remove it, and run two wires to a pot. You could install the pot in the dash for simplicity but it's very handy if you install it in the backside of the wiper switch; a small enough pot will actually fit. I twisted the two wires (to help noise immunity) and ran them up the left side of the steering column; be careful with your routing so they don't get pinched when the steering wheel is moved. I have an inline two pin connector to ease install. Like I said you may need to tune the resistance range a bit before finalizing the install. On my car the pot resistance range is 0-370K ohms but on the S70 it came out 100K - 520K range. I don't think it was because of different models; I think it's just because of the tolerances in the different relays. YMMV. I have a bunch of resistors I used for trimming but you could use trim pots too to make it quicker. The first pots I bought turned out to be junk (couldn't handle the soldering heat) but the part label in the pics worked well. Let me know if you questions. I can add more details later.. https://www.dropbox.com/sh/8cvhfgho63ekwk6/AABwqlK3J4BBTpv4bmYqoI-ia?dl=0 Oh yeah; getting the back off of the wiper switch can be a biaaaaatch; the bone tool and/or a thin dull blade screwdriver works well. Just go slow and heat may help too. I can draw up a simple schematic if that would help.
  13. RIP You going to frame that and hang it on the garage wall as a memoriaum..?
  14. Yeah sure, really.... (wink, wink, nudge, nudge.. know what I mean.. say no more..) Wait a sec.. bolts-on mods don't count..?!
  15. Holy crap dude!! It's been decades since I've seen one of these... you know what they called these back in the day? WidowMakers! Be careful man.. https://en.wikipedia.org/wiki/Kawasaki_triple
  16. Just to be AR, and FYI, the cams turn at half speed of the crank; not 2x (i.e. faster). But your point about listening for the cadence of the noise is still valid..
  17. I would think the bores being too loose and more likely to cause piston rock, which is always a concern anyway with short skirt pistons, would be more likely to cause skirts cracking. If the bores were too tight you would see scuffing/seize marks on the skirts and bores (aluminum melting from friction and moving from the piston to the cyl). H., did you see any abrasion marks on the skirts? What about the top of the pistons; any sign of mottling at all? This would be sign of pre-ignition or detonation, but may not see it on forged pistons. Did you have adaptive-knock turned off? Very interested in what (if anything) you hear back from wiseco.. some quick googling yielded this; seems this is certainly not the first time something like this has happened (is an old thread though) http://www.dsmtuners.com/threads/cracked-wiseco-piston-skirts.140790/ H; i just converted .03-.05mmm; that's about 0.0012" to 0.002"; that seems awfully tight for forged pistons of that size bore..! Are you sure that's correct? This is a good read too, and relevant: http://www.underhoodservice.com/getting-a-fix-on-piston-diagnosis-and-inspection/
  18. In addition to my email notifications not working (unless someone quotes my post), the emoticons are no longer available either. Again, is it just me? Tried both FF and IE browsers, same thing; click on the emoticon menu dialog and each emoticon dissolves to this display.. Update: did you guys do something? They are working now.. or are you just trying to make it look like...
  19. Do you think they'll warranty it...? http://www.wiseco.com/ReturnPolicy.aspx uh, probably not.. Hussein, give yourself time to think on this; obviously your call, but we'd all hate to see this legend of a car die.. {:^(
  20. You can fab your own out of 1/4" plexiglas; that's what I did. Sand it with it like 200 grit to get it to smooth, but matte, finish. Then paint with satin black; looks almost factory IMO. BTW I've seen others fit 3 gauges in that same single DIN space. https://www.dropbox.com/sh/3qgcehwq887wz3x/AAATPi3fXce5dzsw8-sJ08cCa?dl=0
  21. You buy a beater for couple of Gs; drive it while the XR is down, and then sell it once the XR is back on the road for what you paid for it (or more, since I'm sure you'll fix it up!).. what's to lose? couple of quick examples: http://newyork.craigslist.org/wch/cto/5223452773.html http://newyork.craigslist.org/wch/cto/5210299049.html
  22. Noooo!!! Why not just pick up a winter beater for cheap while the XR is down? Just a WAG but kinda sounds like #3 piston is cracked or something.. BTW: what CR pistons are you running? 9:1?
  23. Pretty f****** sweet!! Can't tell from here but what kind of electronics you got in there? A micro-controller proto board plus level-changing logic? BTW: how is it that you have any spare time?!
  24. Very nice! You guys that can weld like that frigging amaze me; very cool indeed.. Stock intake manifold? Temporary?
