thinking of running a lsvtec with PR3 pistons, and milling about 20 thou off the haed, this will give about 12:1 CR

will there be piston to valve clearance issues with biggish cams, like Toda B's?

cheers for any input

 

r u going 2 clay it or plastigage if u want 12 run ctr take some material out smooth the dome out and u can still make 12:1 easy without milling and a 3 layer mls gasket

 

yeah, will be claying it for sure, just wanted to know if anyone has tried this combo and whether there was an issue with using big cams and a milled head...

 

dave...wat computer u going to use with these setup??

 

u could machine valve reliefs on the pistons to make them bigger but it should b fine i am using skunk 2

 

will just be startign off with a VAFC + chipped PR3 ecu, worked fine for my B20VTEC...

the higher compression might mean i will have to go with Hondata... but that is a longer term goal...

i think i will just clay the pistons before assembly and if required, i will cut the reliefs...

thanks all

 

hmm, i know that after milling 25 thousandths you'll run into problems with ctr cams. so with toda bs? be careful. clay check
