Wow, this is looking way better than I thought! Nice runners, smooth corners, looks MUCH better then the standard manifold :D

Defenitly going to look into this after I'm back from holiday, this HAS to make a difference :)

Thanks for posting the photo's so quickly Vocky :)

Will the ECU still bolt to the new manifold? Or does that need to find a new home?

Cheers,

Mark

totally agree, it looks designed for performance rather than economy :D

I'm going to make a mounting bracket which will use the three mountings on the 2.4 manifold.

been busy this afternoon, made the adaptor plate for my 68mm tb :D

your astra engine spec will love this manifold, don't you wish we could of bought this years ago :LOL:
Sure do :(, but TBH I'm surprised our American cousins have taken so long to try this, considering the availability of all the L850 family :?

the 2.4 engine only came out in 2006 and then someone had to figure out it fitted :roll:

2.0sc tb adaptor flange fitted

2.0sc throttle body fitted, I've refitted the vacuum takeoff to the sc tb

I decided to turn the tb so the butterfly opens with the flow from the inlet pipework

how much hp do u think this will give on a standard engine?

seems to be a worthwhile and relatively cheap mod

I'm not sure, but the design is performance biased (about time too GM :LOL: )

the venom manifold which costs $1000 claims about 5-10 bhp and the 2.4 design looks almost identical dunno..


what do you think notsure.gif

I think the 2.4 looks better :eek:

just whipped off the inlet manifold from my vx.

well happy :D

my ported 2.4 is a perfect port match to my ported head thumbup

my ported 2.2 inlet was a couple of mm smaller on the outlet ports compared to the head inlet ports :roll:

so this proves the 2.4 has bigger runners all the way through :D

found a major problem :cry:

the usa cars have a different alternator to the european cars and the result is our alternator is in the way by about 10mm :(

So I spent many hours trying to figure out a way to make it fit :roll:

first I tried modifying the alternator end plate, but the inlet still hit the alternator :(

acdn.z22se.com_userpix_13_IMGP1280_1.jpg


then I removed the plastic end cap and bolted the +12v cable directly to the alternator and fitted a seperate suppressor/capacitor.
[the plastic end cap houses an inbuilt suppressor/capacitor and a spacer for the +12v cable]

acdn.z22se.com_userpix_13_IMGP1282_1.jpg


so finally the 2.4 inlet manifold is now bolted on my vx220

acdn.z22se.com_userpix_13_IMGP1284_1.jpg


So the list of things that need modifying gets longer

1, alternator - remove end cap and fit a suppressor/capacitor [done]
2, replace servo vacuum hose - longer/ larger diameter piece required [done]
3, replace servo vacuum hose one way valve - to match new hose
4, ecu mounting - make a couple of brackets
5, dip stick tube - make a bracket
6, egr - remove pipe and fit a blanking plate to head [done]

Looks great mate 8)

Where have you mounted the ECU notsure.gif

:)

thanx, it was hard work leaning into a vx220 for five hours :roll:

I have since reconnected the ecu in the original position, but it will require some brackets, nothing fancy :LOL:

I will post pics when they're made :)
