want one now

want one now

I'm not selling it yet

if it goes well I might keep it and leave the itb's

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

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

That part number doesnt come up on the uk dealers system....bugger

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

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

your astra engine spec will love this manifold, don't you wish we could of bought this years ago

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:

some more pics

spot the difference notsure.gif

removed brackets :roll:

standard gasket and MAP sensor fitted

 

[vocky]

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

What's the adaptor made off vocky looks like MDF notsure.gif

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 )

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

 

[blue se2]

Defo think the 2.4 looks neater can't wait to hear what ya think when its fitted so pull ya finger out lol.

just whipped off the inlet manifold from my vx.

well happy

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

 

[luna_s]

nice

think ill start trying to get one now then heh

 

[vocky]

found a major problem

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

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]

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

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

I will post pics when they're made
