S5 turbo short block vs. S5 na short block.
 

So I finally got my S5 motor over here from Redmond. I had planned on a large streetport and rebuild then putting the shortblock in the GSL-SE, however upon closer inspection, the housings are S5 TURBO housings (4 port.) I am wondering if I can just swap over the end plates to 6PI, or is the whole motor different? I know the turbos have a lower compression, and the high compression NA is what I am after. What will this effect and how?:scratch:
Thanks, Robert.

You will want to change the rotors, front cover, all Irons. :(

yeah basically it would be better for you to use everything from the GSL-SE motor or use the t2 and do an s5 t2 conversion

well if you need to get rid of that engine, please PM me. (or any of the housings/plates)

OK so I am now looking for an NA S5 shortblock within MAZDA spec, in trade for this S5 TURBO shortblock. I will post it up in the FS WTB section.
THANKS GUYS!
