I also matched the upper and lower manifolds with the dremel and sandpaper.

The HR upper manifold (or M370) is a mess inside. The molded halves weren't meeting up correctly inside the runners. Turbulence was almost certainly reduced after I smoothed everything out, but I have no dynos to prove anything.

One thing to look out for when installing just the upper manifold:
There is room for the upper manifold to move around in relation to the lower manifold due sloppy tolerances in the bolts and holes that line up the two manifolds. This could cause a less than optimal flow. So if you're anal about it like I am, your best bet is to remove the upper and lower manifolds and match them. Then make a note of how they need to be attached to avoid a kink in the flow. There is probably an ~2 mm movement possible between the upper an lower manifolds on my Z. It might not matter, but I feel better knowing that everything now functions like one continuous runner with no kinks or sharp angles.

Makes sense. What AZ should do it gasket match the items. That way you're way oversized on the parts so that 2mm wiggle room shouldn't matter.

So a lot of work needs to be done. You can see lips, edges, and gasket marks where a good 1/8" of porting can be done to gasket match. Over all I think a lot of flow can be increased here.

As for the work getting done I'm not sure its going to be AZ. I still cannot get a response from him. I have a call out to someone else. I'll report back with what cost might run.

AZ is MIA?

He's making overflow tanks :-)

He asked me what aluminum I'd like a few days ago, lol

Very odd, since he pretty much lived here while he was trying to drum up business for his overflow tank.

I see him online everyday but no response to several pms. I did just get one from them but it doesn't look good.

Maxbore.com throttle body boring service and repair quoted me $99 per TB.

Can Extrudehone work with the composite upper manifold?

I've always heard "No" because the compounds used will just gall up the plastic.

Frankly I'm gonna send my spare plenum + 300 bucks to Z1 and call it a win, rather than spending a lot of time and money trying to do it cheaper.

I figure if I see obvious defects on the lower, I will take it somewhere local and get it matched to the plenum, that paired with the bored TBs should get me 10hp or so at least, then I'm officially "done" on N/A mods.

Is there enough room between the lower manifold and the head for a phenolic gasket? I haven't had one apart yet.

I'm sure you could accommodate it, especially if you remove the engine cover.

To what end tho?

Chuck33079 · 03-07-2014, 08:30 AM

Just to keep any heat out of the lower manifold. I have no doubt it would help things on the theory level, but it probably falls into the same category as deleting the throttle body coolant lines- helpful in theory, unnoticable in practice.

Oh I misread, between the head and the lower mani. Probably not unless you milled the flange.
