ok well im building my rb26 head and have ordered tomei 10.8mm lift cams with tomei type a springs, im just wondering how good the standard rb26 valve spring retainers are, if anyone has had problems with them failing or if i need to upgrade them. or wat upgraded ones are good to use. last thing i want is for it to drop a valve. cheers liam

Get the titanium retainers as well mate with the extra pressure of the upgraded valve springs you will split the standard retainers and i got the tomei type b valve springs and they come with the retainers.

Are the type B's, a dual spring? Apparently, any cams with more than 10.50mm of lift require dual springs for a bit of added insurance incase of valve bounce.

i believe there is type C also, these are a duel spring and come with a set of reinforced retainers these are going in to my forged build and are costing me about $1100

just get the supertech set up. double springs titanium retainers and good for 13mm lift. about 600 deliverd

+2

Went from another performance spring manufacture to super tech and literally went from 480rwhp too 596 rwhp.

Back to back with nothing else changed but the tune to suit th new springs that would actually work over 22 psi

Old post, saves starting a new one

Il prob be changing my valve springs when I do my cams, I see a lot of brands like Brian Crower, hks, greddy etc that come without retainers, are the stock ones good enough for these replacement single valave springs?

Only looking at running poncams around 9.1lift

Still running standard valves but with new valve guides, seats etc

To much seat pressure is not good. You need to know what it is you want first. Then build around that.

I dont see a need for so much lift. 10.5 and higher.

In short ro much seat pressure just loads up everything in line with to much stress.

Thats just my to cents.

But I guess I should have asked you what are your hp goal. Sorry

Most proberbly go type r poncams so around 250x9.1 lift,,,nothing extreme

Won't be going double valve springs as there no need for my choice of cams, just wanted to know if standard retainers will be fine with upgraded single valve springs

Ok I got my cams now looking into valve springs

When do you need to run a titanium retainer?

How much is too much seat pressure? Is 80-90lbs seat pressure closed and about 180-190lbs open too much?

Will be running around 26-28psi boost and rev to 8200rpm

We have had GReddy springs with stock everything for years. 264 and a 272 with 9.7 lift. Used to rev it to 9500 and havent seen an issue after about 8000klms. Most of its life its spent on the dyno or the drag strip so its not being babied at all. We run 25psi apart from when its being driven to and from the dyno or drag strip ;)

      Slimline sub on the rear parcel shelf is doable. Pioneer TS-WX140DA is only 70mm high.

      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.

      Misfire/stalling issues

      Easiest way to know is to break out the multimeter and measure it when cold, then measure all the resistances again once it gets hot enough to misfire. Both the original ignitor and the J Replace version. Factory service manual will have the spec for the terminal measurements.

      Yes that sounds right. Cars currently in the shop for the engine work. Will need to remeasure .. but yes I think I must be targeting 45cm from fender.
