I'm considering selling the 91 polished and chromed 91 vh valve covers. I can't use them since I'll be running 94 heads and even though the valve covers look alike, they aren't compatible. They were polished by the best in town and the polish job literally looks like chrome. You've seen them in some of my earlier pics.

Anyone interested please drop me an email at [email protected]

I will send more pics on request.

You should probably link this thread in the Q45 forum. Lots of VH geeks in there looking for different stuff for their Q's.

So are you saying you can fit top feed injectors and those rails under the standard manifold? I hope so!!!!!!!!!!

On the passenger-side bank, yeah. All I had to do is chop a small aluminum nipple off the underside of the spider.

Now, on the driver's side bank, you can expect some trouble since the spider dips down where the throttle body bolts up to .

Here are some pics of the valve covers.

Tecni....awesome work. I'm following this one closely.

Is that a Mazworx transmission adapter? My bellhousing is with them right now but I'm afraid it might not work.

Yeah its from Mazworx. Why do you think it won't work?

Not meaning to clog up your thread, but my starter sits in a different location than on the Z32s. Instead of bolting in through the side, mine comes in through the front and there's an arch in the bellhousing to clear the starter. The part that Mazworx machines is going to interfere with the starter arch, but I'm not sure by how much....

It might be as simple as trimming the adapter slightly and using 5 of the 6 bolts to mount the adapter to the VH. Just not sure how much custom work Mazworx is wanting to do.

I had actually bought a VH starter which sits where yours does and infiniti was nice enough to swap it out for a J30 starter which is exactly the same as the 300zx so that it bolts up to the tranny instead.

Why don't you just get a 300zx starter and forget about your old starter?I had to trim the adapter a bit and I lost a mounting point but 5 screws is enough.

Nice work man. By the quality of your work, you must do this stuff for a living. Do you work in an Orlando performance shop?

I think what Tmorgan is saying is that his transmission doesn't have the option for mounting a starter to it. The pathy starter bolts to the engine on the VG just like the VH. I fink...

If that's the case then the only two things he should be worried about is getting a VH starter and making sure it works on the 300zx flywheel. The tranny adapter is still going to need some trimming.

VH starter probably won't mesh with the Z32 flywheel. The teeth of the flywheel are curved in one direction and I don't believe a front mounted starter will mesh with a rear mounted starter flywheel and vise versa.

Now... you may be able to make it work with Mettler's custom flywheel. Its specifically designed to work with the VH.

Quick update:-20 AN fitting welded to the front of the Thermostat housing. This eliminates the radiator fill cap, PCV vlave and distribution block.

On this pic I was just polishing up on my UMMM... polishing skills. Now I remember why I pay so much to get stuff polished! Coz its a pain in the @$$.

I have done this and it is a real mission to fill the engine with water/coolant. It air locks and I've found I have to remove top rad hose and fill engine from there. I'm going to refit a filling cap in a similar place to solve the problem.

yeah that's because your radiator sits lower than the top of of your motor. If I encounter a problem, I'll just put it back on.

I had to chop off my fill neck to make clearance for the hood the other day and was wondering how it would affect the whole air lock thing. I think if I have to have some kind of bleeder it would probably be just a piece of alum tube with a bolt in it for bleeding the air out. It's going to be close though so I guess we'll see.

Newayz that's one smooth build. You've still got a long road ahead of you but the end result will be well worth the hard work!

I plan to drill and tap a hole on top of the thermistat houseing and install a 1/4 "t-bar" bleeder screw. we use them on heating systems at work.

you may not even need to add a bleeder in...you can use a vaccum system to pull coolant in, but a bleeder still should be fitted..this is how they bleed muranos now since the radiator is lower than the heads.i have the air lock issue with my motor because the radiator sits lower than my head does but the bleeder is the highest point and when using a coolant funnel im able to get almost all of the air out.

Somebody requested a pic showing the inside of the runners. Here's a look:

Ah, I forgot about those things. I used to work at my uncles shop and the mech had one of those. One of the most useful tools in the shop!

Something like this one:

No, my radiator is higher than the engine. The engine is about 50 to 100mm lower than the radiator and th cap is a little bit higher again. The problem is it airlocks and before the thermostat open it start creating steam and blowing water out.

Couldn't you bleed it through one of the temp sensors?

Log style manifolds for now. I don't want to get too crazy (IE equal length) and end up with something that wont fit. Flow won't fe the greatest but it will definitely do the job.
