when i asked in the n/a part i was asked "why i wanted to make my car into a racecar" because i want bigger cams

Dont listen to them. Cams are a personal thing some people love big cams, some people hate 'em. If you like the sound of an engine with bigger cams in it, then for an n/a engine with the mods your car alrady has on it, cams and tuning to suit are a logical step.

^^ agreed

its just proving a little hard too find cams to go in the r34 non turbo at the moment all i can seem to find is the ones for turbo.

Im not 100% sure on this but you might find your best bet is to go with r33 rb25det cams, and change the cam angle sensor drive in the front of the cam to suit your r34 cam angle sensor. Im pretty sure r34 turbo are solid cam, where as non turbo is hydraulic, so for simplicity if you stay with hydraulic cams from other rb25 engines, other than the cam angle sensor i think they should fit straight in (any one feel free to tell me if i've over looked something else). Im not sure what the assembled height of the valve spring on the non turbo neo is like compared to the turbo rb25, i wouldn't think it could possibly be any worse, so valve springs should to be able to be sorted one way or another.

If you add adjustable cam wheels, then the fact that they are "turbo cams" really should not matter, as long as the lift and duration are relatively larger than standard. Whoever tunes the car will be able to adjust the lobe seperation to suit n/a application with the cam wheels. For all intents and purposes, lobe seperation is the biggest difference between n/a cams and turbo cams, so with adjustable cam wheels, this is not such an issue.

Hope that helps, but like i said dont quote me on this. Im going on memory for all of it, and i may have overlooked something. But it would be a good place to start

      R33 GTR lift points for hoist

      By sunsetR33 · Posted

      Hi all. I am aware there is lots of discussions about jacking points, where to lift the car and what not. But as usual just a lot of "in my opinion" and nothing definitive, and everyone does it in a different way. I want to hear from some experienced people on which points on the car it's okay/safe/recommended to lift the car using a four point hoist/lift. I will attach some images of my underbody. Sills are largely okayish, the driver side jacking point is pretty mangled though and it looks like the underfloor is slightly pushed in too, but I might be wrong. In the German Skyline forum, the consensus is to use the sidemember chassis rails in the front and the rear subframe? bushing in the rear. I know the manual says to never use the sidemember for loading but lots of folk do it and it was definitely done on my car too as they are slightly bent too. Based on the images, what points do I use to not make the already present damage worse? I'd use wood or rubber blocks to spread the load across a bigger area of course.

      Ticking Sound On Idle - Rb25

      By MBS206 · Posted

      Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.

      Ticking Sound On Idle - Rb25

      By GTSBoy · Posted

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers
