Guys,

I am looking for some advice.

I am planning my next Fuel Injected engine, and after having tried both a centrally mounted plenum and ITBs on mt trusty old 1835cc, I am ready to move one step up the performace stage

So the engine in question is a 2110 oxyboxer, and the plan is to turbo-charge it. Therefore I will not go overboard with hugely expensive heads etc, so my plan was to use "stock" CB 044 heads, and for intake system, a German plenum and TB.

The basic idea here is to bake a "bullet proof" bottom end (hence the oxy), and cheap, off-the-shelf heads, and then "compensate" with boost when the extra power is needed. In order to keep the off-boost driveability (this will go into my daily driver '62 Ghia) I am aiming for 40x35.5 valves.

So to the question:

Will the old trusty CB end castings do the trick, or do I need to use the (newer?) so-called "high flow injection end pieces" ? The price difference is quite significant, so I am wondering if anyone could shed some light on this issue before I make up my mind.

IMO... I think you'll be fine with the standard CB EFI end castings..

X2.

The standard ones work fine

Thanks, guys, then I have a plan

Does anybody by accident have an extra pair lying around?

I've got a German plenum but no end castings.

are you thinking of making some from stock endcastings?

I already have the German plenum, just the end castings I am after.

I might consider making a set of a pair of stock end castings, but I would like to have a set of the CB ones to have a closer look at anyways There is always something to learn by looking at other people's work

indeed there is!

Turbo Bob runs this set-up. He would be a good person to talk to:

Go with ITBs. I've had both, and I would never consider any setup with conjoined intake runners again.
