79280zx

I just bought a set of 4 16x8.25 xxr 553 +2 offset. I mounted 245-50-16 rear and 225-50-16 front(falken ziex ze950) The rears are perfect without modification. The fronts will need about a 5-10mm spacer for clearance between rubber and strut. The rim fit ok with about 1mm clearance before mounting tires to rims. I mounted wheels to vehicle with about 1/8" washers behind the wheel and they fit nicely as well. Should not have any clearance issues. They also look perfect and i would recommend them to all 280zx owners trying to get away from the cookie cutters. Total price for rims and tires was under $800. Edit-washers used as spacers were for test fit purposes only, do not use washers as spacers while driving.

thanks grumpy, the info from edelbrock will definately help me understand their carbs more. I think im going to invest in an a/f meter to help me diagnos this problem. Wish me luck. Luke

Hi all, i have an annoying problem and im not sure where to start diagnosing. i have a 79 zx w/ 88 sbc tbi block and heads(home ported). its got an edelbrock perfomer intake and 1405 carb vacuum sec. 700r4 w/ 2400 stall. after it warms up i get a terrible stumble about 10 feet off the line when i stomp it. it occurs right around 2500-3200,its like hitting a wall... my car pulls hard for a half a second and then missfires badly. i had the stock 1200 stall converter in the car for a while and had it "tuned" and it ran fine, as long as i didnt try to stomp it from a dead stop, as it would sputter/stutter just the same it does, but at a lower rpm. it seems to only do this once its warmed up a while. Could super hot intake air be the cause? or is my fuel boiling in the bowls? im not much of a carb tuner. Maybe the accel pump running out too soon causing lean sputter? the car pulls great once past this point, but i want to roast my tires soooo bad sometimes,(as we all do at times) and its so irritating because i just get vvrroompopperuuewapfjdda... i wish i could record the noise as im sure its some no brainer for someone with more knowledge. any advice? the pump shot is in the middle hole. should i try a diff hole? i dont want to do anything detrimental to my engine.
