If you want to make changes, there is no need to email or call us beforehand, just place the order with the standard kit the way you want it, and then call us right after you place the order and ask us to modify the order in the cart. We can then refund you or bill you for the difference needed. Thanks.

  • Cody
    the title says this top end rebuild kit is for the SRT4 and 95-99 Neon 2.4 swap. Are the cams that come with it for the Neon SRT-4 or 1st gen neon?
    1 Answer
    • customer service rep
      This listing is for 2.4 engines. If you have a 95-99 Neon with a 2.4 swap and want 2.0 cams we can substitute for you, simply place an order for this kit and call us afterwards to switch to 2.0 cams, no problem.

    Hello I currently have the S256 borg Warner set up that I purchased from you guys and it's amazing. I put down 400 horsepower to the wheels and about 410 torque I have a custom DiabloSport predicator tune that has a 93 octane tune, I'll be going to be swiching to a e85 tune I have a shop that has custom tune for me I was looking to do the crane 16 with eagles rods is this a good setup for me to increase horsepower or should I do the bottom end setup first?
    1 Answer
    • customer service rep
      We would definitely recommend building the bottom end first, as the stock rods/pistons are god only to about 430 wheel hp. So, by you beefing up the bottom end with stronger pistons and rods, you'll be able to make more power, more reliably.

    Just wandering if I can stick with 750 injectors for the zeta 2.8? Also, will the stock bottom end hold up to the power of that turbo?
    1 Answer
    • customer service rep
      The Zeta 2.8 is designed to make 400-500 hp. 750CC injectors have a ceiling of around high 300 hp, and the stock engine really cant take more than about 430 wheel hp. So, if you really want to use the Zeta 2.8 properly you need 1000 cc injectors and a built motor.

    Do I have to order the retainers separate to run the stage 3 cams?
    1 Answer
    • customer service rep
      What you MUST have to run cams, is stronger valve springs. Those come with this kit. Retainers are nice to have, but optional and not required.
  • Cody
    does this kit come with new head bolts?
    1 Answer
    • Customer Service Rep
      Head bolts are not included, so you can choose if you want oem bolts, or ARP head bolts.
  • Brady
    Will I gain horsepower with this kit if I choose the stage 3 cams? If so, how much?
    1 Answer
    • Customer Service Rep
      If you have a big turbo, cams like the stage 3 could give you an additional 35 horsepower or more near redline.
  • Brady
    Does this come with Crower cams or Brian Crower?

      Crower.
  • cory
    Does this kit come with spring retainers and if so what kind and is there anything else needed to complete the head besides valve cover and head bolts?
    1 Answer
    • Customer Service Rep
      No these do not come with retainers. Normally you reuse your factory ones, or if you want you can get aftermarket ones from us. The only parts that are not included in regards to a absolute complete rebuild would be retainers, valves, head bolts (or studs) and valve seals.
  • Lindsay
    Is it possible to get this kit with the Rhodes lifters and the 2.7L followers?
    1 Answer
    • Customer Service Rep
      Sure, for any changes to this kit, its best to order it through our website and then call us shortly afterwards for us to modify the order.
  • Austin
    Would a stage three cam (either or) have any interference issues with a 8.5:1 compression ratio? And if so what would you recommend, keep the 8.0:1 ratio or change cams?
    1 Answer
    • Customer Service Rep
      We have never heard of any interference issues any lower compression (8.0:1 up to 9.0:1) pistons with big cams ever. Of course, when you are assembling a motor with big cams its best to check clearance just to be safe.
  • Noe
    Do the springs come with retainers
    1 Answer
    • Customer Service Rep
      When changing your valve springs, you can reuse your stock retainers. Or if you want an upgrade, you can get aftermarket chromoly or titanium retainers. But neither the chromoly or titanium retainers are in this kit as this is a base kit.
  • David a
    I wanna go with stage 2 cams which has more of an aggressive sound Brian crower or crower cam
    1 Answer
    • Customer Service Rep
      Crower cams have a more aggressive cam lope sound if you are comparing same stage cams between Crower and Brian Crower.
  • Kody Stone
    Hey guys, I was curious, does this kit come with valve guides? I know it does not include retainers, valves, head bolts, and valve seals but I could not find any mention to the guides.
    1 Answer
    • Customer Service Rep
      Valve guides are not included in this kit and are sold separately.
