hmmm. Thanks.

Id still be making off though. cheaper than a full c5 swap.

 

Post up the price quotes, that'll give us a better idea as to what would be the best option. The turn around time, and having a C5 block sounds pretty appetizing

 

a ITR block iwth a SiR would be a killer combo. i think you should do it.

 

build the c5 block and put the b16 head on it. thats what i would do remmy

 

if my compression calculators are correct (im too lazy to do it by hand) then you will yield a lower compression if you use a GSR instead of an ITR. a lot less. as in the GSR is 9.78:1 and with the ITR its 10.8:1. the GSR/SiR would be a better combo for boost.
