Looks like you've taken a hole punch to the inside!

 

I'd be nervous of any tailgaters. :lol:

anything behind the rear part of the roll cage and rear suspension pickup points isn't really required in this case :).

You actually can cut everything from the rear of the suspension out to save weight as its not needed as long as you have a good weld in cage. I have a Harry Hockley Suzuki Swift rally car and it went for a HH lightening experience. Was like a long haired boy going in the Army and coming out bald :lol: The doors and all rear sound so tinney as everything has been cut out, literally, as the cage gives everthing the strength.

Today I bit the bullet and mad some progress. Once the thing was on its wheels, we'd had to catch up on our race car stuff and that continued through the season. Out of it's parking place now:

Rich wanted one of Colin's spherical jointed gear linkage set ups, rather than the original cables. because one of the lever on the box works in reverse of the BE box, it was designed for, Colin made a lovely pivot lever, which sadly is out of this pic, but the bellcrank on the subframe is visible in all it's chunky glory:

OctBlog03.JPG

 

How it's looking currently inside the car:

OctBlog04.JPG

 

I'll be cracking on with the wiring shortly, but I wanted to get the engine sorted out first. It had been smoking a little in the 309 and I suspected old/hardened stem seals; also running it often without filters, meant some valve seat recession was likely, so a head rebuild seemed prudent. On removing the head, the cylinder bores looked in really good shape. The bores are fibre reinforced alloy in this engine and very durable. No signs of scuffing or ridging, which is good.

Most of the engines I've been doing recently are Peugeot TU and XU, so very familiar. As soon as I get a Honda head on the bench, the sheer quality of the castings and machining is immediately apparent! This is Honda tech of 1991 really, but Peugeot still haven't caught it up! The ladder plates overthe cams serve to greatly improve the valve train stiffness and hence precision. They also carry the shower lubrication of the cams and followers:

OctBlog05.JPG

 

With the cams removed you can see the VTEC assembly on the right of this pic (the other side is removed, making the valves/springs visible:

OctBlog06.JPG

 

There's three cam followers per cylinder as you can see. The outer two operate the valves normally, from mild cam lobes. On this head, they pivot on a large shaft (on the left of these), the cam operates on the polished pads and opens the valves (on the right of this pic) at about 1.55:1 ratio (1.55mm valve lift = 1mm cam lift).

The middle rocker follows the VTEC cam lobe, but is normally just floating on a spring fitted beneath it (lost motion assembly). When the VTEC solenoid is activated, by oil pressure down the shaft, two pins lock the three lobes per cylinder together, so both valves open according to the VTEC cam lobe, which is wilder than the other lobes and overrides them. Dead simple really, but incredibly cleverly executed and unbelievably reliable in standard form!

If you're really eagle eyed, you'll notice this head has doiuble valve springs as standard (as do most DOHC VTEC engines).

 

Back when a Type-R really was something special, (ahem), the red cam cover indicated that the engine employed a number of specific improvements, that raised it above the rest of the engine range. Most notably, the ports would be hand finished. As far as I'm aware, the Accord was the last production TR engine to have this. CTR engines are just machined. On this head, it's only the throat blending that has been done by hand and it would appear, only on the inlet side, but it's one of those little reminders of how much passion the engineers that created it had!

Once stripped,the head seems much simpler and you can see where the "lost motion" spring sits in this pic:

There's alot of bits come out of it!

Considering the old theory, the less you put in, the less things to go wrong, its a really incredible thing to get your head around. Thanks for the pics :ph34r:

Nice to see an update on the car! Lets hope its not as long a gap till the next one :ph34r:

 

Also nice to know how the VTEC finally works, always wondered really and pictures speak thousands as one might say.

Maybe I should combine my 2.2 Prelude (when I eventually get around to doing something to it!) and my 309 :)

 

Car looks awesome. Can't wait to see it finished
