Got My Manifold (thanks Coupe72001 )

[harvo]

So yeah I got another manifold (stamped E30) for the Holley. It still needs an adapter but is a nicer lookin piece of kit then the one on the motor now.

What I need to know is when you guys change carby's/extractors what of the associated gear can be chucked in the leftovers pile and what needs to be kept connected?

I would like to remove as much shit as I can to tidy up the engine bay

Can this pipe coming out of the block to exhaust be deleted

The 20mm one with the smaller one off the side?

What else can go?

Also need a longer acclerator cable if anyone knows of anything useful?

Cheers Dan

This is the new manifold and adapter so far

so shiny

Harvo, those are crank breathers. For years on my L28 I've just had a breather/filter (K&N) on the end of the 20mm one and the smaller of the two venting to atmosphere.

Having looked at a bunch of Jap Nostalgia mags, it seems that everyone has a different idea about what to to with the crank breather; I've seen it blocked off with a welsh plug, connected with a hose to the rocker cover breather and finally allowed to vent to atmosphere via a filter. I'm with Ricky on this one, a little K and N filter tucked out of harm's way seems like the way to go.

As soon as I get my car back (this weekend) from the carby tuners I'll post some engine bay pics for you to compare with; as I have deleted as much as possible from my engine! No air con, power steer, EFI, ECU, AFM... it's pretty much bare bones.

Once again; it's great to see such an interesting project coming along.

very good explanation here...

Alrighty, thanks guys I'm slowly getting it sorted.

This is why I asked about the crank breather, the supercharger inlet is a tight fit on all sides.

So, If I cut the crank breather off a little closer to the block (removing the smaller vent hose all together) and plumb that to my crude little catch can will that remove the need for the PCV valve?

and if I go down this path, what then do I need to do with the fuel tank vent which is connected to the small crank case vent via this valve that also goes to the air filter housing.

Thanks again for your help, I'm all for leaving stuff as is (if it ain't broke), but most of this stuff will be redundant once the new manifold/Holley goes on.

so.....I tried fitting the new manifold but it's fouling on the old exhaust manifold heat exchanger, so I'm going to need to get a set of extractors I think.

Not having much luck finding a set for the Datto, just wondering if anything else will work, patrol/240/260/280z? anything else? I'm sure I've read that the z's won't work.

Cheers Dan

R30 extractors fit a treat. Most of my exhaust is R30 - you only run into problems around halfshafts/rear muffler.

I suspect that 240K extractors will fit, but maybe pointing in a bit of a strange angle under the car.

Also regarding the previous posts about what to do with the crank/rocker breathers, I was informed at the NDSOC show and shine if I want to do a sprint or hill climb in my car (and God knows I do) I will need to plumb both those guys into a canister or catch can of at least 1L capacity like your awesome Red Bull set up.

[coupe72001]

Oh yeah - don't try the Z stuff. Patrol, not too sure.

[harvo]

Ahh, thankyou good sir.

The patrol stuff looks to come down fairly sharply then sweep back, same basket as the z stuff i think.

As for my catch can, It came with my old KE70 turbo wagon and was replaced asap cause it was just to hectic for the car. It'll do for now untill I can make a new one.

Time to go shopping
