Many thanks Mark..
Yes...got a little side tracked with the head....it was not originally in the plan, I just loved the look of it and figured I'd give it a crack...

PM replied too, thanks mate.

Thanks B.
Started to re-do the head a little last night....it's still a bit fat. Plus about 4mm too high. A mate gave me some real dimensions to go by.

Many thanks AzN 2NR ....
That IS a very kool clip, and yes, I have seen it before..always fun to watch again though....

Got some more done yesterday and this morning....
The head is finally taking shape, inlet runners/tubes are made, just need to add a bend to each..

Here is the stock motor set up (on the right) with my spare motor and new head.
Height difference is negligible, so I am really pleased I trimmed the thickness of it...


Exhaust port side.


Inlet side. I made 6 adaptors to bolt on here, they will be made to suit Webbers or a turbo...??


Closer look at the new water distribution holes. Flanges added and drilled for tiny bolts.


That's all for now...The rocker cover is shaping up nicely, maybe a pic or two later......
cheers

Love it Greg!

[stump]

Thanks Bill, she's almost done.....

Those funny looking things to the left will become my intake runners...
Just two hollow tubes, siamesed together at one end, then added a bend to each...


Overall view looking down on the head and cam cover...
The oil cap is from the kit, I just added a hole for it to sit in...may leave it with no glue...






That's it till I get those inlet runners sorted....still a work in progress...
cheers

Mmm, eye candy.

To be honest, I'll be sad when this is done, it's a pleasure to watch it come together.

Even the oil cap comes off. Reminds me of hiros r32 progress thread. :

Just one word for it.. WOW..

This is a very interesting and amazing project. I could learn alot from you in determination and patience. I like how you did the interior holes for weight savings. That will look very trick when it's all painted. I think you have more time in the engine then I have in any of my complete models. Great job you are doing. Fun to follow along.

Thanks so much Bill, Mark, Paul and quadzero..

Bill and Mark,
That's what has slowed me down I think....the thought of finishing....
Never fear....whatever ends up on the bench next......be prepared.........
Leaning very heavily towards the 1/12 RX-7.................................... It is just begging for some extra TLC....

[cinqster]

Lovely job...really enjoying your workmanship!

[scorpiopab]

just WOW.

Thank you John and Paul..

Been getting some bench time this weekend......
Also, had some requests to see how it looked in the engine bay......coming up down the page...

First I wanted to check the hood fit....not all that good. I had checked it briefly very early on, but never paid it too much attention.
The fit is horrible. The hood is warped slightly, but it makes a huge difference at all corners....some up, some down....I'll probably display it open.


Finally got the runners almost completed...just some final sanding and smoothing to go.....




The Weber/Solex carbs have had their mating surface "machined"..(trimmed with a #11 blade..)
Their flange was molded as one with the manifold flange, so I thinned it down.
Mocked up, they look right at home hanging off the head....


Not a huge amount of spare room in there...the rocker cover actually hits the hood as well, so I''m modifying the sump to allow it to sit lower...


And with the amount of time I've spent going over ALL the reference pics I have..the engine orientation did not hit me till I test fitted it....
It NEEDS to slant the opposite way.................DOH !

OLD motor set-up......


NEW motor set-up...........


I swapped engine mounts from side to side and cut the gearbox off and re-aligned it.
Sump/oil-pan modifications are progressing nicely...I'm adding "wings" to it to replicate a baffled high capacity unit.

More to come guys, thanks for watching..
cheers
Greg
