    C24se xe head conversion.

    There isn't a lot of info this side of the pond regarding xe conversions. Holden (Vauxhall) here have a rwd ute with the sohc 2.4 and 5 speed in the Holden rodeo. C24se

    I am considering using this platform with an xe head and a set of 45's or tb's.

    Has anyone any experience with this bottom end conversion? I have tried the search function but not come up with much.

    Is it a straight bolt on?
    Any mods or different parts that need sourcing? Cambelt tensioner etc? Oil and water ways.
    Can I use the standard bottom end to begin with.
    Rough estimate of power on standard cams?

    They are about 10 yrs old now so starting to see more in the wreckers yards. On paper it seems like a very economical alternative.

    Thanks in advance,

    Shaun

    No worries Graham. Apparently some of the Irish lads were using the bottom ends for strokers. They found them in forklifts or something. They are a basically a long stroke big bore version of the xe, same family engine, only with sohc.

    Might just need to pick up a bottom end and jump right in.

    Fancy a change after near 20yrs of pintos.

    I did have a good look into this and it keeps coming back on my radar... Really, I cant see why no one here is doing it????

    Complete 2.4se engines can be had for under the equivalent of 100 pounds.

    C20xe holden calibra heads are few and far between however we have plenty of the ecotech versions on astras which would suffice.

    The local wrecker allows you to take a head from one engine and the bottom end from another and only charges you the full engine price so I figure I can get a xe headed 2.4 stroker for under 100 pounds.

    The 2.4se is already rwd, has a rear sump and the 5 speed gearbox will only set you back another 100 pounds.

    Throw on some spare 45's, fab up and exhaust and you should have the basis for a pretty stout engine.

    Bore size is fairly common so finding some pistons and rods wont be a problem should you need to upgrade.

    All I need to do is find some cams.

    There doesn't seem to be much for the xe over here.
    Anyone know where I can find a 2nd hand set to suit?? Otherwise where to shop, Profile? Cost?

    So the question is, what would I be expecting from a 2.4xe, using standard cams, lightly ported ecotec head, 45's and an exhaust? About 170-200hp?

    Not a bad outcome for well under 500 pounds.

    Re: C24se xe head conversion.

    OK so it is going to happen. however it will be slowly over the next couple of years.

    Just over a year ago I managed to be in the right place at the right time to buy a really nice, almost rust free escort from an old man who had put down a deposit on a new car. MK2, 2 litre auto shell. Pretty much the most sort after non RS mk2. He had tried to trade in his trusty mk2 however the dealer wasn't interested in such an old car??? So I got it for a steal!!! Anyway, since I first posted this query, I have been keeping my eye out for redblocks however they are few and far between here in Australia, only coming out in one model car for a very short run. Finally, after 2 years of searching, this morning I found one a a wreckers a Holden Calibra, 4x4 turbo, fitted with the C20let and 6 speed manual. A quick drive out, fingers crossed and found the car pretty much intact, only with a broken rocker cover. Several hours later and several skun knuckles, I now have the elusive (in OZ anyway) twincam head.

    Going to be a steep learning curve as there is little to know info here, but now the build can really start.

    The head is a GM Coscast head and looks to be in exceptional condition. A steal at only $80AUD and I pulled it form a running car. (I have a feeling finding a rocker cover will cost me way more than the head).

    So now I've got the head, got online and also just bought the rwd 5speed gearbox that mates to the C24se!

    Now to chase down a bottom end for the 2.4, a rocker cover and maybe even lash out and get some uprated NA cams.

    I already have a spare pair of 45's and/or also some GSXR throttle bodies if I decide to go that way.



    Here's a pic of the escort......

    For a big cc XE the engine to get hold of is the frontera 2.2 bottom end.

    Why the c22se and not the C24se? My plan is for a 2.4 on a budget.

    I believe the c24 is a totally different block. I’ve done a few with the long stroke Frontera 2.2 bottom end, although mostly I’ve only ever used the crank.

    Well I haven't given up and still slowly collecting parts. This was never going to be a short term project.

    I've now picked up a complete rwd c24se engine so the swap is on.

    As mentioned, I already had the matching 5speed, and I managed to track down a rocker cover for the redtop. It cost me as much as the cylinder head!!!
    Found an alloy tarmac kit (still need rear spoiler), a weld in cage, 5 link kit and a hilux diff for the rear.

    Looks like the cams are going to cost me more than the rest or the engine put together.

    I'll get some pics up later.
