Waste of time?

*Hopefully* getting a new engine for the 205 this week. Its a 50k miles 1360 TU lump from an SPi 106. This means i'll have to swap the camshafts to make it go proper like. I was thinking, as the engine will be apart is it worth slipping a new camshaft in (say a 284degree kent cam) to make things more interesting, or will it just make the car run like a complete turd. The other option is a 270 but i'm not sure how different that actually is from a standard one (anyone know - google has failed me!). If i did swap them would i also be needing new followers, springs, caps as well? And will the standard 32/34 Solex carb be up to the job (maybe a nice big weber is needed :)).

The other (cheaper) option is to just to swap the cams and put in some competition valve springs. ATM the car will only rev to about 6500 before the valves start getting angry. Peak power isnt produced till 6400, so i'm sure it should be revving to around 7000. I've blamed this on a tired engine - do you reckon new springs will help here (ie make valve bounce start later) or maybe the newer springs from the 106 will do?

Thats enough of my ramblings, so any advice about improving the engine whilst its out will be appreciated (particularly Matt is he's about).

Loading thread data ...

get some 1300cc rallye parts, that should do the trick (very similar engine afaik)

Indeed a very similar engine 1294 8v TU vs 1360 8v TU, but i wouldnt be surprised if the engine is the same internally. Externally it has Twin carbs (205 version) or MPi (106 version). Twin carbs are ruled out by MSA regs for road rallying, and i think the MPi is as well - and if not it would be too much work for little gain, probably easier just to get a 106 - incidentally i know of one for £1500 (damn lack of spare cash!). Not too mention how rare (and therefore expensive) the Rallye parts are

Suits me :) Seriously though, i thought i would look into it as i would have the engine out and the head in biits.

Personnally i might be inclinded to pop the head on the new engine, check what its like, possibly have the valves out and lap them in with some fine paste, and whilst i was at it, take the requisit few thou off the head to get to 9.5-9.8:1 CR which should be fine on 95unleaded, possibly with abit of octane booster.

Install the XS cam but stop at that. I would be very wary at installing a used cam into a different used engine and expecting it to work as the maker intended. At the very least replace the followers and valve springs- especially as you say the valves are prone to bounce. I would personnally replace the cam with new as well. The piper 270 is close to stock but any more cam is going to push peak power up still further and for rallying you want a strong linear torque curve, especially if the 'box isn't overly close.

Cheers for the advice. Once i move house this weekend, i will be able to check my finances and decide exactly what i can afford to do. And the box is very close as standard!

But its like group 10 or 11 or something, whereas the 205 XS is lower.

buts its fairly rare, and puts out a lot of power (for a 1.3). I'd imagine it'd be higher than the XS and i'm paying anough for that!

Hi carl, me again .. we have spoken before. I modified my citroen axgt, which has the same 1360cc engine but the car is lighter its sister car, the pug 205. Kit includes: Twin cold air feeds from under the front bumper to the solex twin choke carb, thats fitted with k and n filter and both carb jets are 8 percent larger than stock. (No more, no less ... 8 percent). Big bore scorpion exhaust (good job i'm a welder).

285 degree original billet kent cam with new rockers ... this was carefully timed to 102/102 degrees with true piston top dead centre. (I did all the usual valve grinding/decoking/head skimming/etc).

Just for good measure, i fitted a new clutch and a lower ratio pug xs gearbox.

The car is MENTAL ... much quicker to 120mph then my bmw 730i and bmw 525e .... although it reaches 7000rpm at 128mph!!! (0-60mph in 7 secs, 0-100mph in 19secs). Its as fast as the new astra turbo, mucho fun!!!

Alas, my dream seven series bmw came along, so bought it ... and the 'lil citroen will be up for sale soon. Keep watching the adverts in max power magazine!!

i doubt that very much

max power? well that says it all really.

Not really. the guy has beemers and an AX. I would expect the 7 series to make it into Marques of disinction, (maybe at the bottom end), but the AX GT should go into MP.

You target the advert at the type of person most likely to buy it. And he won't be a company director, unless he does motorsport at weekends.

Hello again How did it run with the 285 in it? Its still gonna be used as my daily driver, so dont wanna make it a complete bitch low down. Do you know the specs of the original cam? The next one down is a 270, and i wouldnt be surprised if that was roughly what it has now.

Already got that ;)

Havent read that for quite a few years :) But if you have any spare parts laying about, then let us know!
