Wooo Hoooo!!! Australia into round 2 this morning cheers - Simon

Gidday Pete, sorry to hear about the pain. . . . Im thinking of pulling out my block in a couple of weekends, can I rely on you for a hand? you'll be better by then wont you? Seriously though, hope everything goes well, us Ozzies are thinking of you! Cheers - Simon

The boys are probably right with the bent stub axle, but if that pans out, I had a similar problem with one of my rears and it turned out to be an out-of-round tyre. Replaced it, and problem fixed. It would be easy to spot, just put the wheel on a balancer and you should be able to see the problem. cheers - Simon

Thanks Dave and Davy, I'm definately going to get the alignment played with, and have to play with my front strut towers, so will soften off the front inserts. Im running about 2 degrees negative on the back at the moment so I'll get that reduced and drop the rear tyre pressure a bit. At the moment my boost is set with a pneumatic valve that adds pressure to the top of the diaphragm. . .I hope to have time to add another valve and switch it with a gas solenoid so that I can run 17psi (its been dyno'd up to that) I normally run 15psi. These cold evenings will help a bit too Id guess. Thanks very much for you help - Much appreciate it and will tell you how I go. cheers - Simon

Hi all, Our club is thinking of going to a strip near us and I was thinking of having a go. Its running on street tyres and presently the alignment is setup more for track work than street or dragging. I wont be changing the tyres, but might get time to get it in to be aligned differently. What I need is some tips on setting up the car and what to do on the night. My car is turbo'd and running an LSD any tips would be appreciated - thanks Zbuild

230rwkw (308hp), 15psi, L28, Motec computer, highway cruising with wife in car 28-30mpg - wife out of car - scarey

When I had mine done, they balanced crank, rods, pistons in one session, then they dowelled the flywheel and balanced it separately then they bolted on the pressure plate and balanced the flywheel/pressureplate assembly together. Because of the dowelling the pressure plate can only go on one way. cheers - Simon

BPR6EIX Iridiums - I run between 15 and 17psi and really like these. They are a bit more pricey here in OZ but I see you guys in the states can get them for around $6.87us each. . . I saw them at http://www.clubplug.net/index.html here they are more like $20aus ($14us) cheers - Simon

Where is the popping noise coming from? is it down around the headers that you have just installed? Did you use a new gasket when you installed them? The popping noise could be exhaust gas leaking past the headers and if its leaking you may also be sucking air in past the gasket into your inlet manifold. If you are sucking air in, you engine will be running way lean, hence the problem. First you need to figure out where that noise is coming from and fix that up. Once that's fixed, if it still wont run, look elsewhere. In this process, did you remove the cap from the distributor or the leads from the cap. . . .if so. . .you may have them on in the wrong order. good luck - Simon

When I built mine I heard near the outlet of the turbo

It is a very common head straightening process. One of the reasons they do it is that if you machine it in its present state (bent) you combustion chamber volumes will vary quite considerably from the edges to the middle. It would be the reverse of cc'ing your head is that de-cc cheers - Simon

Gidday 280zforce if Ive done it right there are 2 pics, the working bits of the breather are a bit hard to see, but at the bottom front corner of the tank are 2 pipes, one goes to the return valve (the second pic) and the other goes to the breather from the block. inside the top half of the tank is a cage holding stainless steel wool to separate out the oil vapour which then runs back down to the sump. cheers - Simon

I run both my block breather and my tappet cover breather to a catch can and at the bottom of the catch can Ive got a drain with a one-way valve back into the sump. At the top of the catch can is a series of filtered holes that let the can breath to the atmosphere. I did this because I heard that if you use a PVC valve it can draw oil vapour back into your engine which can cause detonation in a highly boosted engine. I run 15psi & 17psi with a TO4. cheers - Simon

Gidday again Dennis, what sort of money did it cost to have your diff sorted? mine is seriously lashy and I think my 'limited' slip isn't as limited as it used to be Cheers simon

PS Dennis, talk to Stewart Wilkins about gear boxes too, I know he can fit the likes of skyline boxes behind the L Series engines. I run a Sylvia Turbo box behind mine. . they have wider gears and mine has taken a fair caning without too much complaint cheers again
