Jackson Racing doesn't recommend changing the cams.integra123 said:Which cams would everyone say be better for the JRSC? My motor is fully built..fully ported and polished head, 10:5:1 compression, forged bottom end.
All motor it makes 189 hp and 145 ftlbs on a dynapack.
Im going to boost it with a JRSC and wondering if I should leave the 404 in there or swap it out for a JG 301 cams. What do you guys think??
lift 445 intake 434 exhaust
duration 299 intake 291 exhaust
JG 301 spec
lift 417 intake 408 exhaust
duration 274 intake 250 exhaust
With the test they did (not after-market cams though) used ITR cams on gsr and gsr on ITR, they lost power.
I was planning on getting the CROWER 62402T-2 for the non-vtec model.
They are made for turbo and Superchager set-ups.
They have less of a duration 203intake and 203 exhaust but a much higher lift 469 intake and 460 exhaust.
I am still not sure on what I will do yet. I will be increasing my boost by 2psi and adding hondata s200 this year. Next year forge the engine and then I'll decide about cams after alot of research!!!
