    you are going to need a very friendly engineer but before that you are going to have to find out if you can register the car with that engine in it

    IF you can then you are going to have to do some work to the front end to hold it up with that great lump of iron sitting in the front end and then when you have done that it may probably never ever handle the way the car should as it will be a lead tipped arrow

    you are going to need a gearbox that is going to handle the 253

    you are in for a bit of work IF you can ever drive it legally

    Seriously, the 253 is a boat anchor. Heavier than a 304, 308 or 350, but with much less power, much less tuning potential and uses just as much fuel. You'd be crazy to use anything smaller than the 304.

    However, you'll find that it's very easy to do the conversion. From memory, all the Australian 253s have the trimatic pattern block. If you get a bigger one, make sure that it has the trimatic pattern block.

    Then, get a 604 transmission extension housing, output shaft and speedo drive gears. Fit this to the back of the V8 trimatic. The 604 only has three planetary gears on the output shaft whereas the V8 ones have 4, so it won't be quite as strong, but it will do the trick.

    Engine mounts should be fairly straightforward. Modified XN engine mounts should be pretty close to the money on the V8 engine, otherwise a simple adaptor plate should have it in the right spot. You have about an inch movement in the diff and tailshaft if neccessary, more so if you have the swinging diff setup (pre 1984 505). Remember that in the pug, unlike in a holden, the engine mounts are only taking the weight of the engine and gyroscopic precession, not the reactive torque from the rear axle. They don't need to be heavily engineered.

    The rest of it is just connecting all the usual stuff - exhaust, cooling, electricals, fuel lines, accellerator and choke cables, etc.

    If you want to make it a manual though, you're up for a lot more heartache.

    The biggest problem though, is dealing with all that extra weight over the front axle. The 505's strong point is it's poise and balance, and you're going to seriously compromise both of them. It would be much easier, and nearly as effective, to just go out and buy a VB commodore. Then stick a Pug 2 litre in it

    Wouldn't the Rover 3.5l V8 be a more practical option? From memory it's lighter, smaller and pretty well bullet proof. I know that the 253 is a tough unit, but as mentioned previously they weigh a lot.

    Whilst the 253 rumble would be nice, what about a Jap V6, or even a 1UZF-E Lexus V8? They're also bullet proof and fairly cheap (under $1500 as a half cut if you do your homework), in particular the Lexus V8 is very light in relation to it's size, and a dead easy 200kw.

    I say the SR20DET is a better option (even though i'm not a turbo entusiast), since it keeps the whole thing compact and light, provides plenty of punch, and it's actually been done before (as reported on this very forum!). :p

    The car will retain it's french handling, carry over some japanese reliability and parts availability, provide a very simple tuning platform, be perfectly road legal, and go like stink.

    I'd love to see the look on ricer's faces as a 505 went pissing by them from the lights, BOV a flutterin'.

    It's the gift that keeps on giving! I've found that the 505 is an easily controlled drift car too, provided that sufficient power is available.

    A CA18DET is also a really good option. Cheaper than an SR, but still very strong and reliable, and smaller externally.

    Bowie, I'll PM you next week sometime, as the 505 will be back in Newcastle for good, along with myself.

    Speak with an engineer first on what they will certify

    Cost a mate $1500 in engineers fees to power up his Commodore.
    Nothing really, the crate engine from USA cost $24,000

    They will need to inspect at each stage of the project

    Have fun, deep pockets are required

    Alternatively, you could buy a used engine from someone on this website (or Pugwreck) and rebuild it. SRs have a pretty simple engine. And possibly yours is not as stuffed as you think it is.....strip it down and see.

    why on earth would anyone use a 253 ..... My old CX2400 was faster than 253 slugomatics in commonbores. If your going to the effort of an engine swap.... lookup chev crate motor on ebay. Or if your feeling wealthy, find an old commonbore with an LS series motor in it .... being all alloy there probably not hugely heavier than the existing motor.

    forget the rover v8 .... next to the 253 there probably one of the most gutless v8's ever made .... fuel consumption is spectacular for something that makes so little power. I have two of them here at the moment. If one died I'd go looking for a battered old rover with a small block chev or modern GM engine fitted, and move the conversion kit with V8 into mine.

    Oh Yeah, the one thing the rover v8 has going for it is the sound ...... it's almost worth feeding it silly amounts of fuel just to listen to the tunes it plays

    if you are keen to go ancient technology though .....

    Peugeot 504/505 engine swaps have been proposed and discussed on this forum plenty of times. The general consensus is the best options are:
    604/605 V6 Easiest conversion, would drop straight in. May have to relocate battery. Not hugely powerful without modifications.
    Lexus V8 Easy to source, plenty of power, modern and LIGHT (alloy) V8.
    Mazda 13B Rotary It's been done atleast once. Anybody know what happened to it?

    As for me, I opted to keep the Peugeot motor...

    Edit: I just wised up to the fact that this is a really dead thread.

    Don't knock "forklifts" and don't ever forget the Coventry climax engine. I suspect the CC engines were well before your time.

    However you might remember Sir Jack Brabham who drove open wheeler race cars in 1962, 1963, 1964 and 1965, both of Brabham and Lotus origins powered with much modified Coventry climax forklift/ fire pump engines.

    And don't forget that the venerable R12 engine was used in some bobcats!

    Agree with the verdict on the 253. My Dad had a Commodore with one in it; what a load of rubbish that engine was.
