I can't remember which site I read this on. I'm turning up allsorts looking for the RML information I need lol. i saved these pics the other day and meant to stick them up here.

Obviously we know the reason that they reversed the head on the CX20XE, lower intake temps and a slight ram air affect. It seems this was the third and final evoloution of the engine in terms of STW spec.

Below is the first gen. With a large pipe used to feed the throttle bodies. This was binned as the friction of the air in the pipe actually made it hotter than if it was fed directly from the bay as standard.

Below is the second generation, and has asnwered a question I have often wondered. The head is still in the standard rotation, but there is the addition of a huge CF plenum for a more direct air feed. Which was a lot better.

This is where the crazy 'over the gearbox' style exhaust manifold comes from. I forget who has one on here? I recall there being discussion as to whether it would be of benefit though.

It seems that it didn't make much if any difference, and it's only purpose was to allow the engine to be lowered in the bay so with the CF intake fitted the bonnet would still close. lol


...well I find it interesting. :thumb:

Tis interesting. Forgot the guys name (sorry), who owns that welsh exhaust place who has/had the turbo over the gearbox.

Gareth from WCC? Has he not moved the tubo there for space reasons though?

I'm tempted to say it's Bigs who has the Cav STW manifold.

Ahh yeah bigs has one too, for the wide arch.

And it may of been space reasons, makes sence really.

colonchin! So all these people with cold air feeds are probably making the air hotter.

Tut, people will be raising their bonnets next to make things cooler!

Maybe not, swindon were flowing enough air for 290ish bhp remember, that's more friction.

Bigs manifold will still be insane, "not much difference" will be compared to a previous swindon design, although with exhausts it's like black magic matching it to engines, sometimes it just doesn't work without the crows beak in with the cams and half a frogs leg in the intake lol

The pre crazy manifold reminds me of a Hotshot mild steel job or is it the BTB you get for Vauxhalls?

IMO the one pictured isn't that flash as at this stage, 93/94? The money being polughed into these cars wasn't astronomical.

Compare that to 2000 (iirc) when they ran the night race and the headlights were supposedly three grand. lol

bigs manifold seems to sit quite high off the gearbox?


Maybe I'm missing something here, but reversing a cylinder head doesn't seem like that much hassle? lol

All you are really changing is the cam positions, valves and ports?

Surely they would have opened the valves right up so then exhaust/inlet valves could go wherever, same for the ports?

As the basic cast of the head is fairly symmetrical. Ignoring the belts - which don't affect this anyway. There is the distributor cam drive but I guess that's out of the window with the ST setup.

Is there much more to it?

*having a discussion with MK999 via MSN about this now. I have seen modified heads that have the cam cover the corrct way but the exhaust/inlet on the 'wrong' side, albeit not Vauxhalls. As the one on page one is clearly rotated 180* and makes me look an even bigger n00b. lol

*Clarification. lol

Blind leading the blind really, took me a minute to figure out if they had to run the engine backwards to get it to work lol

All I know is they can't rotate the block.

Maybe I'll just look at the pretty pics in awe. lol

I have reasons lol. Been ill. Now I await confirmation of the correct gauge steel to come in stock at my suppliers.

Sorry mate. :( lol

I have the Volvo hub/strut adaption to keep me ticking over though.

In the true spirit of the internet I have said some stupid stuff on this page lol.

The main being I was picturing an engine without a gearbox, so the flywheel was forgotten about in one thought process.

Just thought I'd pwn myself before someone else does. lol

Are there any graphs or figures for the various stages of development or is that generally unknown.

the main gains from the reversed head as a better exhaust route... the "ram air" was a mild benefit for a while but not the reason the reversing was done.

Considering the fitment of that exhaust BIGS has I would sell it to someone running a ex racer and buy Giles's manifold off him which will fit as long as he dry sumps it
