  1. If you were running stock boost before this turbo change then you have turbo injectors because you'd have leaned out with NA injectors. When was the last time your injectors were cleaned? Have you checked each for proper function?
  2. Ok, so stock turbo injectors. If you haven't raised the boost to much more than 10 psi you're ok with the stock injectors. The wideband sensor and controller need to be tested.
  3. You failed to specify what engine the stock injectors are for. If for an NA engine then yes, you need bigger injectors. If for a turbo engine then that isn't your problem. Have you gotten an msq from someone with a basic turbo setup and tried it?
  4. If it will work with solid lifters then it looks to be pretty close to the "C" cam and would work well... Not so sure it would work with the hydro lifters - that lift figure is a big bump and not much more duration to tame it...
  5. That would be .443 lift and 212° @ .050 lift, total duration of 260°...and whatever the radius of the base circle was reduced by is what you would add to the lash pads thickness. That is the way Schneider derives their figure for their hydraulic grind that MSA now sells. Did he keep the same opening rate/ramp angles as original? If so it's probably too steep for non-hydraulic lifters. The amount of lift might be too much for hydraulic lifters. If in fact he kept the same ramp angles as original then I'd say that cam is useless.
  6. You're probably gonna be better off with getting one of the Isky cams that have been documented on this site because of the hydraulic profile. BTW - what are the specs on the regrind that Delta did and what lash pads did they say to use?
  7. Actually a bit self serving on my part - I want to know if someone CAN Regrind a turbo P90a cam with a bit more duration and a bit higher lift that will work. I'm only looking for peak power at 5800 rpm and max rpm ~6k.
  8. You can probably get away with a bit more duration but not much more lift. He will have to tell you what thickness of lash pads to use to make up for the smaller base circle.
  9. If a lobe is bad you probably can't regrind the cam.
  10. You need another stock P90a cam or use timeserts to use a mechanical cam. The best of those would be the "c" cam used in the 260's, but you might have problems w/ internal and external oiling.
  11. I believe the ZXT distributor uses an optical sensor.
  12. I think I would go with a stock square port exhaust manifold that you match the ports to gasket with and go from there after ceramic coating it. If you want to go for max power equal length headers are ok, but I've seen tests on turbo cars and using cast exhaust manifold weren't much of a liability and provided better low end.
  13. Take it to a muffler shop and have them install two v-band clamps...
