i have a 93 gsr and i baught ctr pistons.my qustion is will they fit,or will they hit the head.some say yes some say no.any help would be appreciated.

 

They'll drop into your bottom end just fine and this is a very common build... As for the piston to valve clearance, that all depends on the cams... There would be no reason to run some insanely big cams with high lift and lots of duration since your compression isn't that high... Something along the lines of CTR/ITR cams would be a better option for power and for piston-valve clearance... Without any milling of the block/head you should be fine at 0,0... If you are worried about cam advance/retard then clay the motor... Good Luck

 

yes they will fit and work but i suggest not to use the gsr head because it will ping or detonate due to cumbustion chamber and valve clearance from the head to the ctr piston might be dangerous

 

Pistons will work, and not hit the head. Your compression will not be extremely high because the 93 GSR uses a B16 head, not the later model P72 head with the smaller combustion chambers.

 

youre lookin at 11.3:1 compression good luck!

 

you'll be fine...its only OEM parts, not some insane full race spec. monster piston. just clay and check the clearances and you'll be straight.

 

the 93 GSr is the B17a, correct, I think the thread author should have clarified this, cause it may not be widely known.

Also, the b17a is just a factory stroked B16 block, correct folks?

i have a 'similar' setup on my hatch... will be tuning it with hondata s100 within a week or so. i set it up for road racing...
