I like the nerve gas idear but ........ What about putting another ignition coil under the seat connected to the recluctor coil with hidden kill switch, the faster they rev the more they buzz What about shorting out /blowing up the battery use lots of transistors or scrs to short it out What about just overload the battery so it will flatten quickly a stainlessteel exhaust might work, use the batt maybe melt part of the exhaust out would be very noisy to drive

Have been grinding, polishing and flow testing Had .070 machined off the head (just starting to cut into the bottom of the "nissan" logo now) Chamber vol 38.5cc to 39 cc approx 10.5:1 on the compression ratio i think it's my best guess http://smokingwheels.myphotoalbum.com/view_photo.php?set_albumName=MyEngine&id=head_polished_chamber_by_hand will have more info soon

we had traveled about 5 kms had to turn out of a drive way to get on the road the key was in and on so the indicators could work stuffed if i know what happend

I had a feeling that is was gonna be one of those days so i took the camera just incase. I was being towed home, cause it shot a one conrod cap thru the sump,another was in the sump also punched a nice hole in the side of the block, oh yes i was giving it heaps, a $650.00 bang. here is a pic to prove the keys where in it http://smokingwheels.myphotoalbum.com/view_photo.php?set_albumName=album01&id=3_on_the_move while being towed going arround a small corner the steering wheel lock up. here is the pick of what i did ,I jammed on the hanbrake almost instantly http://smokingwheels.myphotoalbum.com/view_photo.php?set_albumName=album01&id=6_at_least_the_handbrake_works_both_wheels here is the curb i mounted http://smokingwheels.myphotoalbum.com/view_photo.php?set_albumName=album01&id=5_The_start_of_handbrakie and the a skided to a stop and parked it http://smokingwheels.myphotoalbum.com/view_photo.php?set_albumName=album01&id=7_not_bad_parking_rear_wheel_skid_steer well it was one of those days

ive been looking at the megasquirt fuel injection system for my z. http://www.bgsoflex.com/megasquirt.html its in kit form so you have to build and tune the system. Also a LED Duty Cycle Meter for Fuel Injected Cars Part Number: KC5375 Automatically operate an extra fuel injector or fuel pump etc, when your fuel injector duty cycle reaches a preset level. http://www.volt.com.au/cgi-bin/browse.cgi?category=579&sc_add=888800046&ecomsvr=1034821010 there is more kits there to.

ok here are some graphs http://smokingwheels.myphotoalbum.com/view_album.php?set_albumName=2003

hey this is cool site ! i worked 180B head on L20b engine that ran on a timing curve like this http://us.f1f.yahoofs.com/bc/40c02149/bc/Mail+Attachments/gregs_engine_RPMDATA_12675_image001.gif?CCBzjkCBGKJtEK3t total useless past 3000 rpm with stock dizzy but used to go good with about 25 deg to much advance and never melted the pistons! and what a racket it used to make in the beging after bolting it down i nearly lifted the roof off the car port trying to start it then The big bang +flash of light split the mufflers open like they where wet paper bags it used to carbon up plugs in about 3 months ,heat range 12 i think i still have a few of them,the bearings in block lasted less than a year i later reduced the comp ratio 8 to 1 this brought the total advance back to 22 deg past 3000rpm. i felt my old engine at 8 to 1 comp had more power than the stock one im running now i also found that changing the L20 cam to a L18 cam made a slight diffrence the knocking was less with the same timing ,but no recorded values . here is a graph ,the top 2 points are real the rest a guess at best http://us.f1f.yahoofs.com/bc/40c02149/bc/Mail+Attachments/estamate_of_compression_ratio.bmp?CCbxkkCBUavaCqTh sorry this one is 2.1 meg my mate ......helped me toss the motor out but we didnt rip the head off :eek: im about to start work/recreate this strange thing again on a 4 cyc head in my bluebird which now has a notebook fitted to control the timing. this program has taken over 5 years to complete. i have data recording on accerelation figures on current motor eg 1st gear is about 13 to 14 rpm increase per pistion firing. the computer is not that fast only 200mhz but will run a 4 cyc near 10K rpm just ive got 3 inputs hooked up to change things like vac adv,temp, revlimiter. if my new one runs ok i will port the head on 280zx the same way. does anybody know how many deg overhead is on the L28 dissy? i need 55 to 60 deg to play with. can i disconnect the wiring to the dissy and redirect it to my computer or does the efi need this signal ? Any comments help Appreciated
