You know you own a Dastun when your missus stands at the window wishing you paid as much attention going over her body as you do the Datsuns.

The UD balancer will slow the water pump down but it won't be slow enough to effect the coolant system. Also stops cavitation at high rpm. I don't think millions of LS owners would run them if they were crap. I'm interested about the PTV clearance issue you had with that cam. Was the cam advanced? Or was the cylinder head shaved for a higher compression? I'm thinking more of a 228-230 cam now, with less than 0.600 lift, something that retains standard lifters and pulls from 2500-6500ish.

Hi, I'm looking at upgrading the cam in my standard 2001' LS1 (in my 240Z). I dont mind going something big as this is just my weekend car and not a daily driver. Maybe 232/234 or 238/240 etc. Apart from the cam this engine will have ported and polished 241 heads with about 20th shaved, 25% UD balancer, ARP head, cam, balancer and bolts, LS6 injectors, ported factory throttle body, LS6 manifold. My questions to the LS gurus are a follows: What size cam or rpm limit can still have the standard lifters? At what size cam do you require solid lifters? At what point does the LS1/6 run into piston to valve clearance issues? I know I will need new pushrods but I will measure the gap once the heads are installed, I already have PAC1218 springs. I'm sure I will have more Q's but that its for now. Thanks in advance.

Certainly mate. I sent you a PM. I dont have a link for you, but google or youtube HSVSUX. Its a New Zealand based circuit racing sedan (Holden VL Commdore) with a tricked up Jatco behind an RB30ET. Cheers

I finally bit the bullet and got some Rota Grid Drifts. Running 16" x 8" +10 with 225 Dunlop Formula R semi slicks on them. I think I'm in love with my car now.

Here's my LS1

Yeah mate these are still for sale. I sent you an email. Cheers

Mine are just blocked off.

The black Rotas are much better than the bright orange.........in my opinion.

Yeah it would be. I do have coil overs but any height adjustment I can gain above the top hat increases my strut travel. The added camber and castor would have been nice too. Aftermarket looks easier.

I cant seem to find a place that just sells the pillow balls or something similar. Usually they are inside a big housing or a rod end.

And can you buy pillow balls separately if you were building your own strut top and wanted to incorporate one. Thanks for your help.

How are the mono balls or pillow balls secured on the strut tops?

What do you mean exactly. The factory strut top bearing will still sit inside that cup allowing rotation of the top spring perch.

I've cut open one of these and heated up the rubber so it popped out. I'm doing this for the purpose of investigating how I can: 1. Modify them as a non adjustable strut top with added camber and castor. 2. Shorten the strut top itself to gain some extra strut travel at the same (lowered) ride height as before.

Ahhhh, I comprehendo now.

Are talking about the strut top bearing? Perhaps that is more of a bearing issue, as in the strut top is loading up the top of the strut tube during turning rather than the bearing taking the load. Those ones mentioned above are a good price but I'd like to know what people think of the contour camber plates (fourth one down).

FYI, after a couple of requests, I've found a supplier of a softer spring that can be used as a stage II shift kit (for those too scared of the stage III) PM me if interested.

LS1 injectors are supposed to run at 60psi but if you're blowing hoses at 80psi then there is a weak point there (hose wise) that I would be fixing. I would take a punt here and say you've got a vacuum hose hooked up to the reg when you shouldnt have. NA LS1's run a constant fuel pressure where as other models run variable. Most regs have a vacuum port to hook your manifold pressure up to but in your case you dont need it.

I've got all the parts I need for my stage 1 upgrades ;D (I've been playing too much GT5) LS6 manifold LS6 injectors I've ported and polished my throttle body to 78mm, and will port manifold to suit. PAC 1218 valve springs (rev limter here we come) Removing fuel rail Throttle body off LS1 manifold off LS1 on left, LS6 on right. Waiting for the LS6 manifold installation Well the LS6 manifold has been installed but after also installing the LS6 injectors, I was advised to wait until it gets a tune otherwise they'd run too rich, so the LS1 injectors went back in. I think the seat-of-the-pants-o-meter has picked up some improvement in the top end just by changing the manifold. I ported the entry to manifold as well as spare throttle body which required me to make up a new 78mm throttle blade as the factory size is 75mm. I haven't installed this bigger throttle body yet. Well I havent done too much to this since the last update. I raced it at a local go kart track and split the steering rack bushes, but had lots of fun. Here is a quick vid I took on a 0-200kph (0-120mph) run. I count 0-200km/hr (0-120mph) in 12 seconds, does that sound right. What would that equate to on the 1/4 mile do you think?
