Yeah cheers guys.. One opinion I've been given is 24psi.. But I don't see how that could be the case as long as the spring tension etc is right and you aren't revving it stupidly high you shouldn't get any valve float (which seems to be the issue with these heads throwing shims),

Also I could probably find it somewhere but does anyone know what the biggest cams you can go without losing the vct

Poncams but why are you doing cams anyway? Usually a lot of other priorities for the dollar.

The motor. Once assembled will have I beam rods, wiseco pistons, good oil pump etc. Head will have springs and retainers. +my current gt35 or bigger and all the other bolt ons that go with it. Was just thinking cams may be a good idea while it's going together.

Yeah while its getting bolted together would be the best time to do it or at least get the head relieved so you can do it later, it was some thing I forgot about and am kicking myself now

What cams are you looking at and what head are going to use

Hey guys I have gone ahead with this neo30 build. Instead of starting a new thread I'll just ask in this one.

Have just setup the timing belt with one idler and a tensioner (one above water pump). All the marks line up pretty well. Is it worth while getting an Adjustable cam-gear for the exhaust side?

I'll be keeping VCT so guessing I dont need anything for inlet side

(Standard cams to start with)

Cheers

Ian

I have a spare VCT ring (good for dialing in cams on 30's) for the intake side if you would like to purchase. Apparently they have about 4 deg of movement.

If it was me id do 260 type b poncams/ neo head/Precision 6466 T4 /e85, comp in the low 9's

the only trans that won't explode would be a glide or a Th400.

thats a combo id sell to a customer wanting the best of both worlds

Id prefer a neo head over a 26 head as it would come up quicker on a torque converter due to inlet manifold design

and i bet it would make more power under the curve making it a better street proposition

its a better street deal all round

Need to run into the 8s to even start to justify a 26 head

cheers

I've already got the 35/40 from my sohc setup (it's a VL) and a re401a auto. I Got the manifold with a heap of parts and it has t3 flange so later I'll upgrade the turbo and manifold or just get flange changed. I plan on putting some type b poncams in it but would just like to see the difference from std cams.

Close to 9:1 comp

Specs of motor

Spool I beams

Wiseco pistons

Asr 8.5l sump

Arp main and head studs

N1 oil pump with billet gears and crank collar

Cpc plenum

Steam pipe manifold

Standard head besides springs and retainers

Ross balancer

    • Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf

    • People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.
    • What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
