Would an SPi cam be okay in a turbo engine? I'm looking at between 5 and 10 psi. I was also wondering if an A-series -0.010 at both mains and big ends crank would be okay too.

Thanks in advance,

Will

Hi,

Can't see why not

The MG metro cam used to be a favourite among the turbo guys...

Cheers  :proud:

Cheers Bat, so would you say get a metro cam but that the crank should be fine to use?

The 10/10 crank should be fine providing you are not going for 150hp

 

The SPi cam is a bit short on inlet timing and has extended exhaust timing

 

MG metro cams are good, but in fairly short supply, the MS evolution001 is not far off the MG, its new and value for money when compared to a 2nd hand MG cam which has done how many revs...a MD266 or the milder 256 could also be useful for the road

Thank you! I'll do a bit of research on the cam

Hi,

You don't want anything wild as it will just take longer to spool up the turbo.

As you're pushing the air in rather than hoping the engine will suck it in, the cam can be one with low overlap.

Cheers  :proud:

Pretty sure the spi cam is the same spec ad the standard metro turbo cam.
