From way back in my Honda days, TBs were bored out as big as you could go at the inlet side, but still retained some taper to the outlet side to help with air velocity. A bigger plate was included as part of the work too.

Very interested to see how this project turns out. Thanks for giving it a shot.

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.

man wanna see some results so bad

AZ is MIA?

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

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, 09:30 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.

Yeah, that's too much effort for a difference you'd need lab equipment to notice.

He's making overflow tanks :-)

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

edub370 · 03-07-2014, 10:28 AM

so basically, if i send my tb's and plenum to z1, they will port them out just like that?
