Any of these still available? Got an intermittent connection somewhere, only item not swapped out is the Brian/Todd chip carrier. No chip needed, just the carrier. Thanks much - Barry

Ok, picked up the motor, out of a 1996 Chev van; paid $750 as a running engine. Pulled it apart yesterday, had the correct head casting numbers for the Vortec heads - see www.mortec.com for the numbers. Also turned out to have four bolt mains - *very* nice! Off to the machine shop for...

Just blew my third engine. Can anyone steer me to info on putting a SBC into a Sy? Found some pix of the German twin turbo conversion, not much info. Really want to keep this truck, but stressing this lil' 4.3 to get good numbers - 11.5@117mph - is getting just too tedious. Need a bigger...

I recently PM'd BG in frustration, asking him to impart some sage wisdom on the black art of engine tuning. Been working on this thing for almost three years, every mod except headers - best I could ever do was 12.3 at 107mph. The real meat of his reply was real simple: >Don't *think* about...

I seem to be getting some odd results when trying to tune to a specific AFR via a wideband oxy sensor. Same boost levels, same RPMs give different AFRs - is this normal, or is something FUBAR'ed w/ my setup? For example, I'm after an AFR of 12.2 by adjusting F30 & F77 tables: 3500 RPMs, 3rd...

I'm really gettin' frustrated in obtaining the "rock solid" boost control that some folks calim to have. Built motor, all the goodies except headers; turbo is hybrid, stock center section, Mitsu 14cm turbine, Garrett TE60 compressor; cam, heads, etc. Tried Deltagate, HKS, both in crossover...

Got a problem w/ an externally mounted fuel pump, wonder if any of you guys who run these can help. Pump is mounted inside the frame rail near the front of the tank - so the suction hose is 3' long or so to an added rear sump on the tank. Alls well until I punch it in first gear - then the FP...

What sort of numbers are you guys seeing with respect to boost control in a 1/4 mile run? Like, max during shifts or TC lockup, sags during 3rd & 4th wind out, etc. Interested in comparing integral WGs w/ aftermarket units. Thanks much.

Got the lower A arm completely detatched (replacing ball joints & inner bushings), but the arm, torsion bar & "porkchop" appear to be fused into a single piece. Any special tools or tricks to separate them? GM manual just says, "remove....."... :(

Is there any delay built into the code relative to stepping the WG solenoid to higher or lower values? Reason I ask is, even w/ the delays set to zero (in the data accessable to Promgrammer), I see only one WG boost correction step per ALDL frame, which occurs roughly every 100ms. Seems to me...

At 03A3 & 4 - is this an "engine saving" parameter? IOW, does the fueling stop right NOW, or is there a lean, detonation-prone stage while shutoff is occuring?? Thanks - Barry - Sy#26 Bangor, MI

Anybody know if the driver semiconductor in our ECMs will drive TWO WG solenoids? Thanks - Barry - Sy#26 Bangor, MI

Finally believe I've gotten the most out of a 40# chip; my goal was to get some good (& safe) performance out of this size injector, mainly because "nobody has a good 40# chip". Build is: 1991 ported Vortecs Isky 252/257 cam TE60 / Mitsu 14cm, WG by Chan to 1.43"; 20psi set pressure Base FP =...

Picked up what I was told was the ZQ8 box. This one, on the bench, goes 3 1/4 turns from lock to lock. Haven't got the stocker off yet to compare. Thought the 12.7:1 box was a hair over 2 turns L/L. What have I got here??? Thanks - Barry

Any tricks or tips on a DIY poly bushing install here? Just snapped a 1/2" bolt trying to remove the spring bushing with a big socket & washers. How about the bushing in the frame for the shackle? Man, that bolt flew aways when she snapped! Thanks - Barry

Mended my broke tranny w/ BH's & GB's help. Thanks much, guys! New problem --- What / when do your hear a bad rod and what is the sound like? Got a rattly sound, more like a muffler w/ loose baffles on gentle acelleration & right after getting off the throttle. Made a WOT run, got a few...

Ok, here are the actual, measured figures on the stock SyTy cam. Cam used had =~ 70k miles on it, well maintained engine. Figures are average of 3 readings, probably +/- 1° or better. I/O: @ .006" @.050" Max open: @ 108° ATDC = 0.230" 10° BTDC 18° ATDC Duration: @...

Any experience to share regarding either of these? As in overall quality, plug access, etc. Its time to add that last bit to my Sy, trying to decide on which make to use. Thanks - Barry Sy#26 Bangor, MI
