im thinking of increasing the cc of my metro turbo pistons to 16cc if i did what sort of psi would they take? i am running an intercooler the size of my clubman grill.

also im running a Kent 276 cam atm (obv too lumpy) and ive got a spare mini sport fast road ca2 knocking around, i was thinking of droppin this in with some 1.5 rollers?

advice would be great

cheers eden

hi there, i doubt you could get 16cc in there, on the standard metro pistons,

if you were to place 28cc in the combustion chamber that would be easy a service which i provide. this would give you a compression of 8.5:1 that togeather with a good intercooler and is good for power figures of around 160 bhp ish at around 16 psi of boost, if the rest of the engine ie gearbox clutch etc ...... will stand it.

i would ditch the 1.5 rockers on forced induction engines and my cam choice is phase 2 from avonbar or kent 266 or swifttunes SW5 the choice is yours

hope this helps

thanks benross, so wat sort of pressure wil the turbo pistons take. Ive got a low comp head but im unsure of the figures until i pull it apart in a few weeks

Van has the above config BENROSS mentions and we've regularly been pumping 12-15psi through it and plan on putting more in there!

If something is worth doing, it's worth doing half of.

wuithout knowing your compression ratio its impossible to say what they will take, and naturally it all depends how well its all set up.

so rule of thumb more cc more psi

lower compression ratio - more psi.
Higher compression ratio - less psi.

wats the adverage head mod in cc? I think mines around 15

Ahh the old dislexic line. Writing gd instead of good is not dislexia, it's lazy.

why no 1.5 rockers on forced induction engines ???

You can use them but some cam's are recommended to be used with 1.3 ratio rockers. The Phase 2 is one such cam I believe.

I reckon something like a Kent 266 or SW5 and 1.5's would be a good combo however.

If something is worth doing, it's worth doing half of.

i think i might give my minisport cam ago, not got much too loose

Are you reading anything people say?

The minisport CA2 is apparently similar to an MG metro cam.

im just trying to keep costs down, so unless i come across a cheap cam i dont realy want to buy one.

next question, ae 21268 any good?
