Mark And Duncans R32 Build

[Beer Baron]

yeah it's easy to go nuts on the parts. i'm guilty of a lot of crap i probably don't need but is 'nice' to have. yep, I reckon anythnig under 400rwkw head studs aren't really a neccesity, cam cap studs, well as long as they are good or new, and are installed and torqued in the correct order then there is little chance of anything going wrong with them. the only times i've seen dramas with them is when they are being installed or removed improperly. i've also seen dramas with people installing head studs then having problems due to them not being installed correctly, with studs bottoming out etc. which is why I wouldn't go there unless there is going to be some really serious power and boost to come. over the years as prices on gear came down I guess people just were inclined to fit more serious stuff 'just in case'...

Same thats all i can find - but not really cheap

Prices for them?

Same

i got them for $230 delivered

cams in this head are fairly sizable, 270/280deg 10.8lift

Tiger some wives have their own lappy's and surf in here while hubby cooks dinner.

haha actually some of us have wives who race in r35 GTRs while leaving their hubby at home/work paying the bills

still trying to work out if its a good deal or not?

What's the plan for this weekend? I'm not home til Friday night so can't do any pickups, but the weekend is free. Saturday is better.

not looking good mate....will try to turn a spanner or 2 on sunday

What are you guys using for cam cap bearing studs/bolts?

standard of course. don't forget our budget (ie 0). standard head bolts, standard main bolts, standard cam caps. and all second hand not new. if the motor blows due to failure in one of them someone can tell us "I told you so". otherwise we can just keep saving money where possible

[BezerkR32]

wtf would you need cam cap studs? if you have a cam trying to push through the caps you have serious problems

I stayed out of this one, but I'm glad that someone else has piped in on the need for cam caps studs. Sounds to me like the biggest waste of money that you can put in your engine.

Let's just have a look at the mechanics of the whole thing, the force on the caps comes from the cams and the valve springs only. Under compression the valves are closed and the load is absorbed completely through the valve seals and thus the head bolts/studs.

Springs are inconsequential, even if you have heavier springs, they are not exerting much more force than factory.

So you've left with rotational force of the cams, which is only a product of the weight of the cams and the rpm. I don't know what the weight differece between aftermarket cams and standard is, but it can't be much and even if you are over reving it's unlikely that you will be doing more than 10k rpm (stupidity to be doing this much anyway) so at most a 25% increase.

Take all this into account and you are nowhere near factory tolerance. Add to the fact that studs or bolts and screwed into an aluminum head and it's easy to see that the cam cap bolts are not the weakest part of the chain anyway.

But hey, if you want to spend $230 on bolts, I'll discount them to $229.95 and just head down to Bunnings for some high tensile bolts. I'll even engrave them with whatever Jap brand name you want so that it has the bling factor hidden under the cam covers.

I'll take two sets

Good price, where from?

All the other bolts etc have been upgraded in this motor, so another couple of hundred wont hurt. Even if its not 100% needed, ill be straight above 400rwkw and i dont want it to let go again

I don't think it let go last time due to cam cap stud failure though....

still if you want it, buy it. but we did try to tell you!

No worries, since you didn't specify a brand I'll make them TomJuKS, the new ultimate Kanzai brand!

dan from elite racing got them for me (erd.com.au)

Nope, better pistons and new ECU for this one

This one will have a fair bit more power though

I am still having nightmares about those roads in the wet!!

[giant]

cams studs seem like BS to me too, unless there were other issues or super valve spring pressures on the nose of the lobe! ( coil bind maybe)

[Roy]

meh...anything but "crate" motors from your local japanese wrecker for $400 is overkill

Yeah i tried to think of something good, but i failed.

Re the rear cradle mods I can say it works, as we did to The Slot Car and I went to Wakey last Sat after completing both front and rear geometry changes, by raising pivot points, which raises roll centre, did a PB of 1 min 4.65 which was .8 sec faster than previous 1 min 5.4 when I had done rear pivot points and partial front, and best prior to that was 1 min 6.18 with a few other changes but the main one was raised roll centre. Car is a lot more predictable and flat in corners and does not slide or pitch like it used to, and much safer and easier to drive. Dunc and Mark you will love it.

How do you find the Tein RA vs the Bilsteins? Better? Worse?

Also, how much for a modified rear cradle for a GTSt/GTR, including fresh arms? I wouldnt mind re-co'ing the rear end in my car with all fresh arms, fresh wheel bearings etc. Also need to find a way to replace the rod end off the HICAS as mine are stuffed and Nissan want $400 odd for replacement ball joints. Its not so much the money, but surely there is a better, perhaps more durable way????

[haw001]

Thanks John, can't wait to give it a go. The bushes have been removed and I'm going to weld plates top and bottom to make the joints completely solid.

[haw001]

Roy, I've got a better option for removing hicas entirely. I should have it together tomorrow and Ill post some pictures.

Hey Roy, not cheap although if you grind your cradle bushes flush it raises everything about 25mm as mentioned as long as clearance to chassis is ok, which on R32 GTS-T is ? BTW I noticed no added vibration, although I expected to as locks the cradle to chassis with no bush. We also made a custom lighter Chrome Molly upper control arm in rear like R33/34 type have, as it does not need to go around the shock like Z32 and R32 have, which Nissan realised and lighter. The front upper are custom pivoting models which don't wear out or bend as they don't bind.

Re struts I have tried various spring rates, Tein RA, D2 ( waste of time) HKS, Tein Flex, Tein RE, Bilstein and now actually half and half as in Billy's in rear as abit softer than the Tein for Wakey. Hard to pic although I am now looking at what I think is the ultimate for the price range and that is Brillstein PSS9 adjustable shock version. They have huge range of adjustment
