What is the difference in the ITR block and the GSR block....anything signifacantly different that would stop me from buying the GSR block and poutting an ITR head on it??

 

slightly higher compression pistons, lighter connecting rods and the stock ITR's crankshaft was made wtih some kind of heavy duty steel and was also semi balanced. The b18c1 isn't a terrible block, it came with oil squirters to cool down the pistons and a block girdle. If you can find a cheap c5 block go with that, but a c1 is fine and is gonna be cheaper.

 

right but could i just buy a C1 block and put an itr head on it ??

 

you could, but would have lower compression

 

ya you could if you wanted to, its basically a b16 head with a slight port and polish job, better cams, lightweight valves, single port intake manifold, and i think a 62mm throttle body. It all depends on what your lookind for, if you want to turbo it, Nitrous, or your goin naturally aspirated.

 

not if u change the pistons right??

 

i want to turbo it

 

hum this is a pickle, it would be cheaper to buy a c1 block and put a itr head on it, the compression would be lower and a little better for your turbo. Do what you want man, you could also buy a complete b18b longblock and spend the extra money from the swap on a nice turbo kit


edit: what are you driving now???

 

i could change the compression though with different pistions right??

 

ya you could, you could buy forged pistons that would either lower your compression or higher it. But with forged pistons it would be a good idea to buy better rods too
