piston choices!
Turbo Mini Forums

Ello everyone, have used the search function and looked at many different specs and seen quite a variation in choices of pistons!

For the spec i will be running, the Omega 10/11cc +20 pistons and the MiniSpares MEGA pistons both look good. I cant afford froged pistons unfortuantely :(

Im just starting to get all the bits to put the engine together now as im learning the art of saving haha, so im ready to get these pistons.

I hope to run 1293cc, standard crank/rods with adjustable boost from maybe 10-15psi, intercooled, decent rad, oil cooler etc. but am not sure on the boost front as it will be an everyday car! And eventually will get something like an avonbar modified chamber head.

Will the pistons i have mentioned be up for the job? If so what would be the better choice out of the two, or are there any other pistons that i should be looking at i.e makes and cc's etc.

I know the cc is important for the CR but im still not sure what i should be aiming for and need guidence of my 1st build!

Any help would be fantastic! Cheers again chaps,

Rich

Well - the omegas are lighter I believe - but the MEGA are available (easilly) individually, from any of the minispares locations.

I use the Mega - and will NOT (see below) continue to use them for some time yet, as they really are a cost-effective option.

Only my own personal preference.

Please see this topic for up-to-date info on the suitability of the minispares 'mega' range of pistons for turbo use:

i would say 15 psi is a ideal max level for every day car, that would mean about 8 psi for your normal boost level. using this method then you can see what cr you need, i would say around 8.8 to 1 would be ideal, you dont want to go to low cr if you are not going to run shed loads of boost as i will just eneding up going backwards before you go forwards if you get my drift.

mine is 9.4 to 1 runing 12 psi max and have 145 bannnans but is nice and lively at the bottom with a good fuel econamy.

but in my mind still a tad to high for my liking but like you need to save up and get a head of simon.

always looking for them bigger bunches of bannanas

Thanks for the info guys! Really helpfull! I think im going to get the omega's from MED

Those jets look really nifty too, thanks for that!
