want to replace my 12.8v to a bigger 8.v what are my limits.

[sam13]

right fellers got a few questions for you all in my new corsa project there is a 1.2 8v in it and i want to upgrade it to something bigger that is also an 8v \'\'so you cant tell the difference if you get what i mean\'\' right well according to the corsa book a 1.2 8v will do 0-60 in around 19secs and a 1.4 8v \'single point injection\' will do it in 13sec which is quite a difference but i was wondering weather you can get a 1.6 single point injection which would be even better as i doint really want to change my full wiring loom. when i get engine i will be taking head off having it skimed and i will port poilsh it etc before i put it in and also if i replace it with another 8v engine out of a nova corsa astra etc will they all be stright forwards fits. or if they dont do a 1.6 single point injection would i be able to convert it to one by changing the manifolds\'

my car also has power steering so the p/s pump could also be a problem.

thanks fellers sam

i was gna ask sumthing like this, would an SRI engine fit straight into my ar without any loom changes?

[sam13]

if you have a muti point injection but if you have single point you will have to change your loom!!

[markymicro]

If you upgrade to twin carbs i dont thing you have to the loom i think?

[sam13]

i think im gona get a 1.4 single point and skim the head and polish the ports and paint it up just make it look smart.

thanks fopr you help marky btw hoe is your super tunes 1.2 8v comein on you got the super charger on??

[gareth_towler]

why not just geta 2.0 8v from a vaux cav ???

[markymicro]

Coming along nicley only got to put the charger on then it\'s all done!

[sam13]

i would put a 2ltr 8v out of a cav in it but the engine looks different and then could get cought out lol were as from the 1.2-1.6 they all look the same rli.

glad to hear you engine is all done marky is it alredy in the car?

[markymicro]

No not yet am fabricating the shell befor i put the engine back in.back to what you where saying! but dont forget the engine codes are differant unless you grind them off BUT if the police pull you and they see the codes have been grindered off they will inpound it as the will think it\'s a ringer!! but the code on my engine say c12nz and that says it\'s a 1.2 but it is 1.4 supercharged engine see what am getting at?

[chrisdaman]

what are carburettors? i dont understand what they do, they replace the fuel injection dont they? they increase power dont they?

[markymicro]

Yea you are wright! It\'s just a differante way of mixing the fuel with the air. they are a good bit of kit av got a set on my engine can get up to 25bhp so realy good for performance[br]I got mine off ebay for £160 including p&p not a bad price!!

[chrisdaman]

awesome, cos i want alot of performance without getting raped on my insurance, so engine conversion out of the way, i get paid next week from my 2nd job so that will go towards the carbs, what do i need to look for? and brands, or model types etc

[markymicro]

you need Solex carbs or webbers dont forget you will also need to change the inlet manifold it will be pricey!

not exactly mate,the 1.6 8v looks the same as a 2.0 8v

nly the 1,2 an 1.4 look the same

on the 1.6 upwards they have that little box on the head with the pipe coming out

[sam13]

arrrrrr get ya you recon a 1.8 single point injection would fit stright in with messing around and cgaing loom as no1 seems to know??
cheers sam
