Have a rb25det neo and have purched Tomei Poncams 260degree 9,15mm lift.

And Tomei valve springs type B with Retainers for the intake side why not for the exhaust side aswell??

And do I have to shims the lifters if so How do I do? Any pics?

What is the part number for the springs you have purchased?

Do you have the equipment to change the springs and is the head on the block or off it?

I'm pretty sure that number suits R33 RB25DET, Not Neo.

Correct me if I'm wrong.

Also I don't think springs are required for a 9.15mm lift upgrade on a Neo either.

The springs suits rb25det with solid lifers and I have that stock on my neo so I think it will fitt??

OK but how do I now if I have to shims or not?

These springs will NOT suit your application, they are designed by tomei to work with the solid lifter conversion for an r33 RB25DET not a neo, and honestly your better off spending your money on a set on i think its performance valve springs.. much cheaper and work just as well if not better, the yen is shit and anything from japan is stupidly expensive at the moment.

Exactly what Cartman said.

These springs are for the 33 RB25DET with solid lifter conversion. They do not suit Neo.

What part number did you get for the camshafts?

i had a solid conversion kit and it included the same springs with only one side of retainers.

You should stay with the hydraulic lifters and save the hassle.

its a neo you dingis . how can he stay with hydraulic lifters if he never had them in the first place?

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
