Unearthed a few Sy parts in my garage. Sold the Sy years ago so these need to go. US buyers only. PM box is almost full, feel free to email me at krusep@pacbell.net Stock turbo. Some of the fins look a little worn and one looked bent but it still spooled fine when removed. One stud on...

Bought this years ago, never opened the box. Truck is gone so this needs to disappear. Comes with a Fel-Pro gasket. $75shipped(OBO) to US addresses only.

Bought years ago from apeusa.com ($108 shipped in 2003). Still sitting in the original box and I still have the original receipt. Never installed. Note that the item numbers may not be what they currently recommend for the SyTy's (according to apeusa.com). Please review these p/n's before...

I purchased these for my Sy a while back, never used them. I opened the box just to snap the pictures. SM-AFR w/ DM-5 AFR gauge (black face). $250 shipped (US only).

The truck has been collecting dust for years and I'm not motivated enough to work on it anymore. It's time to get rid of it. I'm in Folsom, CA (95630). VIN# 1GDCT14Z5M8800122. The truck is in major need of a bath since it has been sitting in the garage for a while now. I have driven it 2-3...

I have this second set of wheels that I obviously don't need. Wheel are straight, a little curb rash but still in decent condition. Comes with center caps, locks w/ key and 15 lugs (5 short of a full set). Two front and two rear rims, Toyo Proxes tires which have minimal wear (if any) ...

I have an almost brand new 10n1 Ultimate for sale. Never got it working in my Sy but had another Syty'er install it in their rig to confirm that it works 100%. Chip burned for stock heads, cam, injectors, 3bar MAP, etc. $400 shipped (obo). Complete description can be seen here...

I bought the setup new many years ago (radar style) but had several bad EPROM burns in a row. Out of frustration, since I never got it working right, I just moved on to an Ostrich setup, Tunerpro, etc. w/ 50# injectors. Now that I'm still sitting on the Ultimate that I'm never going to use...

hey all, wrapping up my very lengthy upgrade (6mos) of swapping in a pt63, rpm a2a and new 50# injectors (i work very slow). finally got to fire it up today and it seemed to run fine (on jackstands). i noticed one of the injectors (frontmost on driver's side) was seeping a little gas from the...

i'm not sure if this is the right forum, but here goes. i need to pick up the manifold fitting to connect the sender for my autometer mech temp gauge. do we need the 3/8" or 5/16" version for our tranny lines? thanks, paul

installed my ultimate w/ 3bar map and have been dealing with a stalling problem (truck will die at idle when warmed up). i'm a rookie datamaster user but noticed that my afr tgt is 10.0. does this seem right? i looked at my stock chip dm files and it usually stays right around 14.7. fuel...

just installed my radar style ultimate (v7?) w/ 3bar map. everything seemed to have gone well, but when i fire it up ... the Ultimate displays T3-24 and i am not able to select any different modes. if i press both buttons at the same time i get the XXXX display followed by KEY? which tells me...

Okay guys, I went thru the basic troubleshooting procedures diagnosing why my 1 yr old Jabsco pump isn't powering up. FYI, The pump relay is hotwired. I check the fuse behind the alternator: 12VDC;Good I disconnect the 2 pin connector for the pump, check voltage: 12VDC;Good. So now it...

i have had a prob on my sy for a while where the brake pedal has been spongy and the brake light stays on. i have already rebuilt the master cylinder and it made absolutely no difference (i bled the brakes after the rebuild as well). i am no expert at brakes so maybe someone can chime in here...

i went to three different shops today to get my old bushings pressed out and get the ES pressed back in but none of then said they could do it? one shop said that they would have to torch out the rubber bushing then everything falls apart. another shop said they would just use some penetrating...

currently in the process of rebuilding the front end of my sy. since i have the front sway bar off, i figure i might as well upgrade the sway bar bushings. i got the ES p/n of 3.5186 off sytyauthority. can somebody tell me what this kit consists of? i just called summit and the guy thinks it...

took my sy to a local front end shop and they noted that my ball joints and tie rod ends are worn. the work order also said that the "right upper shaft bushings" are worn. is this another term for the upper control arm bushings or am i dumber than i think? thanks in advance, paul

i was taking a look under the sy and noticed that the front diff is not the original. it appears to be a used one since there is a "91" marking on it using the paint pen (or whatever they usually use at salvage yards to label their stuff). this makes me a little nervous now, are there any...

looking to replace a dead master cylinder for my 91 sy. checked the sytyauthority.net parts list but came up empty (either that or i'm blind). a gm p/n is preferred unless there is an adequate aftermarket stock replacement. thanx in advance. Paul
