Help!

[Paul]

Roughly how much should i pay to have a Piper 272 cam with cam housing, modded head (work already carried out on head), webber twin choke carb with inlet manifold fitted and set up?

I have a standard 1.4SR with K & N and straight through exhaust , what BHP should i be pushing?

I've been told by various companies ?200 cheapest to set up on RR and have it fitted. And also I will be pushing inbetween 100BHP and 130BHP.

I thought 130 was bit high.

[wisewood]

130 is high but achievable so you never know.

[Paul]

Could i safely bore out the cylinders too to around a 1600 or does it weaken them too much?

Im looking at getting them bored out too when i have everything else done.

[courtenaynova]

Mikey Oxford is squeeeeeeeeeeeeezing about 140 from a B+ head with AST2 cam and 1650cc bottom end.

GET THEM CARBS SET UP U MOOOOOOOOOOOOSE!

:D

[Cheese]

Think the most you can bore it to is about another 50cc, but not 100% sure on that! :?
Fit all the parts yourself, then get it setup at the RR, easily done in a day, even if your not sure what your doing. Just follow the Haynes manual! :D

[Jim]

I don't think you'd be able to bore your 1400 to 1600. There wouldn't be enough stroke in the pistons to give you a proper 1600 feel. - might want to check this with someone that knows more about engines.

Piper come in 270 and then 285. the 272 cam would have to be a reprofiled cam from the 270. Go for a 285 cam if you can get hold of one.

I assume the ?200 to set it up doesnt include the parts? Including all the parts, for a proper job with the engine in good condition your looking at about ?1000 - ?1500 I'd have thought.

If you can, get a Performance Exhaust manifold, a 4-2-1 is best. Magnex do a good manifold, but the welding is prone to cracking, so watch out for that.

I'd research it a bit more and try and source some parts yourself. I'd get a B+ head direct from blydenstein (roughly ?500), a 285 cam (roughly ?250), Twin 40 Carbs and ancillaries can be picked up from anywhere between ?200-?500 depending on condition. MC or CP could fit all the components for you and then you'd need to take it to somewhere reputable like "Velos" to get it all set up.

It's expensive work, but "you get what you pay for".

Jim

P.S. You're current car setup should be putting out around 75BHP. A straight through exhaust and K&N Air filter don't do a lot to increase power unfortunatley.

[Stuart]

umm mr mike has only got 125BHP at the fly lol

not the 140 you think

[Dan]

cambs right, i have same mods but lightened and balanced also (no power gain). as said mike ran 125bhp but i ran 140bhp on same rollers back in the summer so it is possible.

[locky]

I thought the 1600 block and the 1400 block was the same, but different head, and stroked out by 8mm iirc!
not 100% sure what that means, but i don't think you need 2 get the cylinders bored out!!!!! :roll:
change the bottom end for a 1600 ne1?

[Jim]

change the bottom end for a 1600 ne1?

I would have thought this would be the most sensible and cheapest option.

Jim

[mikeoxford]

umm mr mike has only got 125BHP at the fly lol

not the 140 you think

*coughs at rob*

i went to velos to get my carbs setup, so why do i need them doing again?

i COULD have squeezed 130 MAYBE out of the rollers if it were on a good run according to velos. and i DID achieve 125.

i had a splutter on my BHP graph. but my torque graph kept rising and rising in a straight line and didnt drop off.

i need different size jets *possibly* that on the day velos didnt have i dont think. but apart from that i could be looking at 130 bhp max.

i need to change my gearbox final drive DESPERATELY as its holding me back loads. i must have the longest ratio cavalier gearbox going!

[mikeoxford]

change the bottom end for a 1600 ne1?

Jim

ive got a 1600 bottom end if your intrested.......?

dont want much for it. just refuse to send it the scrap yard

[Paul]

Right i picked up the carb and inlet from the breakers webber 32/34 thing for ?40.

BOugh cam and follweres etc of Will novanutter,

Bought modded head of will, gas flowed or summit im prob getting confused here but i think he sed work woz dun by CP?? But prolly not.

Iv been qouted ?200 to get this lot fitted and set up, so im going with that. If i have the 1600 bottom end of u mike, how much BHP gain should i get, how much extra do u reckon this wud be to get it put on and set up, and also most importantly will petrol costs go up.

Im gonna struggle a bit on the 1400, if 1600 drinks it like a beast i wont go for that!

Cheers Paul

PS mike have u got a 1600 bottom end on urs and wots it like for petrol, i know u got t40s but does the botom end make it a lot worse?

[wisewood]

i thought mikes was a 1600 8v now?

[Paul]

i dunno i ju guessed at the 1600 bottom end coz it woz still 1600 sr in his features?

ur probs rite andy.

Nebody kno anyone with a 1600 bottom end, or cud sum1 tell me what petrol will be like with 1600 bottom end?

[Will]

paul the bottem end can be overbored to 1480cc

standard is 1389cc for 1.4

1.6 bottem end u have in effect got a 1600 engine code, group 11 insurance and the company i helped u get insurance with wotn touch you.

i think with the mods you are doing u will belooking at 90-100bhp at the fly depends where u go, some places will jsut tell u wot u want to hear

i had 90hp and was happy with and as it will be your 1st car etc id be happy with that as well...........

the piper cam u have off me is 270 or 275 i cant remember, its a good cam, 285 might possibly be lumpy and annoying for a 1st everyday car etc etc!!

head was flowed by cp a year back, it was skimmed at an engineers in northampton as well so it gave a nice tight seal when it all came together.....

will

[Barn]

surely if u bore it out like that u will need new pistons?

paul....i wouldn't be too concerned about fuel consumption coz surely the cam is gunna make it drink petrol like a bitch anyway?

atb :+:

p.s am i right to say u aint driving yet? not meaning to insult ur driving or anything but with this work the car should be well nippy when its done, so my advice...take it easy. i found hell of a difference when I jumped out of my instructors F**d KA 1.3 ( lmao ) and started driving my 1.4SR which only has K&N and exhaust.
just a thought mate

[Jim]

Mike has a 1600 bottom end, has done for some time now. It's actually bored out to 1650cc though.

Fuel consumption wont be that bad.

Someone mentioned your not even driving yet? Ermm, had I known that I would have said "Get yourself a 1.2". I'm sorry to sound like an old man, but the engine you are planning on getting is going to be very fast compared to anything you've driven before (unless you happen to do some sort of circuit racing, in which case I'll shut up). Also, Insurance will kill you, god knows how you plan on insuring it all, even with a 1.4, a 1.6 would be very expensive. Another thing, whats the rush with getting a load of power straight away?

Anyway, It's your car, your money, so I'm going to leave you to it, just do us all a favour and be careful. We dont want to see posts of your sweet looking car on the back of a recovery truck after you put it in a ditch :|

Jim

P.S. The Piper 285 cam isn't as lumpy as people think, just turn up your idle a little bit and it'll be fine :roll:

[Barn]

Someone mentioned your not even driving yet?

^^^^^^ post above mate, lol

[Paul]

I aint drivin yet, iv been driving cars for ages tho of the road. drove sum of me mates cars whioch are quite rapid like a 1.6 mk2 golf that was rapid. 1.8 16v focus, im gonna drive carefully wudnt want to write my beast off.

Im gonna jus go for carb cam and head, which should see 90BHP at the fly, 65BHP at the wheels. That will be quick enough, jus as long as i can keep up wiv all my mates in dis it'll be fine.


1.6 16v escort si, fieasta zetec-s, pug 206 1.4??

[Jim]

Someone mentioned your not even driving yet?

^^^^^^ post above mate, lol

It was a rhetorical question :roll: :P

Jim

[Barn]

It was a rhetorical question :roll: :P

Jim
I wasn't answering the question itself, u said 'someone' so I was just sayin that someone was me mate :?

paul...not sure how u would get on against them cars mate?i aint really got the same problem, most of my mates got like 1.2s n stuff so obviously i p*ss over em. ones got a 1.4 Nova Flair but that is ssssslow compared to my SR.

anyways, all the best
